PUBLIC WORKS STATEMENT BY THE HON. J. G. COATES, MINISTER OF PUBLIC WORKS.

Mr. Speaker,— The various reports and accounts appended to this Statement will show that the total expenditure on railway, hydro-electric, road, bridge, and irrigation construction works during the past financial year has passed all previous records in the history of the Dominion. Expenditure of money need not necessarily have a proportionate result in completed works. If the cost of construction, materials, and labour, be high—as it was during the past financial year — -it follows that special effort must be made to increase the actual result from such outlay. A heavy expenditure has been incurred in the purchase of up-to-date labour-saving machinery, and this means my Department lias been able, despite the relatively high cost of materials and. labour, to produce the maximum result possible in the existing circumstances. The Public Works Statement of last year indicated a policy of concentration on particular works, rather than the diffusion of money and energy on many works. Concentration on works of particular importance means the application of all the financial, mechanical, and human resources of a construction. Department to the completion of these works so that they may soon, become revenue-producing and self-supporting. Diffusion of these resoiirces over a greater number of works inevitably means a lessened reproductive result, and, since interest and sinking fund on unproductive works must be .found'by the taxpayer, an increased capital cost of such works. That I was unable to cany into full effect the policy of concentration * previously outlined, is attributable solely to the effect in this country of the world-wide financial depression, and consequent unemployment. When unemployment became general throughout the Dominion it naturally became a matter of Government policy to assist as far as possible the alleviation of distress. Whatever steps may have been taken in past crises of a similar nature, the Government had no doubt that the true economic remedy was to provide employment in various localities on works of such a nature as would assist in the normal and profitable development of the country. It was accordingly decided to carry on with certain railway-construction works of secondary importance, which in other circumstances would have been closed down, for the time being. While, therefore, I regret to have to state that circumstances necessitated a temporary modification of the policy of concentration and maximum achievement, honourable members may rest assured that every pound devoted by the Government to the relief of unemployment has been expended on road and irrigation works of primary importance, and on railwayworks of not less than secondary importance.

It is of primary importance to the country as a whole that there should be no considerable measure of unemployment. Fortunately, there arc already indications of a return to more normal conditions, and as quickly as circumstances permit concentration on works of first importance will be continued. Such a policy is undoubtedly in the best interest not only of those work's selected for completion but those which will be temporarily deferred, for I have no doubt it will mean that they also will be completed at an earlier date, and at less cost, than would otherwise be the case. It rhay be of interest to honourable members for me to mention a few railway-works which have had special attention and which will continue to be pushed forward to completion or to a payable point. On the North Auckland line the Golden Stairs Tunnel has within the last few days been pierced through on the bottom heading. The heavy work referred to in my last Statement, between the railheads running north from Auckland and south from Whangarei, is now so far advanced that rails should be laid over the whole length, with the exception of a mile, by the end of the year ; and shortly thereafter the through connection of 130 miles of line will be made between Auckland and Whangarei. Owing, however, to the extremely unstable nature of the country in this locality, it will probably be many months before the formation can be brought to a condition of stability to enable the line to be worked by the Railways Department. On the East Coast Main Trunk line—Tauranga eastwards —good progress has been made ; while as to the westwards section, between Tauranga and Katikati, the Department is pushing ahead with the preparation of plans for work to enable the isolated section of over forty miles from Tauranga eastwards to be connected up with the general Working Railways system. I purpose inviting tenders for the construction of this twenty-two - mile section and to have the work completed, and through communication established, with the least possible delay. Unfortunately, the history of big constructional contracts in New Zealand has not been a satisfactory one, and in future, before letting a contract, the Government will have to be thoroughly satisfied that to do so will be in the best interests of the country. Many large works are in hand, and great progress is being made, but the completed results will come into next year's Statement. Work has been continued on a small scale on the Waipu Branch Railway ; nothing has been done on the Waikokowai or Waipa gravel-pit access lines. The Waihi line eastwards to Tauranga has not been suspended as intended, but, on the contrary, the large number of unemployed in the Auckland District has led to an increased number of men being placed on this section of railway. The Gisborne-Wairoa line has also been con inued as a relief work, and a considerable amount of work has been done on the Napier-Eskdale Section and beyond. The Tutira Section of the NapierWairoa line is one which I should like to have taken in hand vigorously and completed to a point where a branch off the main road would enable a large area of profitable country to be served, but I regret that the "ways and means available, after providing for liabilities of work already planned, have not permitted it. Two works of considerable importance which last year I indicated would be concentrated upon with a view to early completion were the Midland Railway and the Waikokopu line. Unfortunately, essential material for both of these works was lost in the wreck of the " Wiltshire ". some months ago, and the delay in obtaining duplicate supplies has to some extent affected the time of completion. Every effort is being made, however, to minimize this unavoidable delay. The good results that were anticipated from the use of modern mechanical construction plant have been fully realized, and are dealt with later. The most significant feature is a reduction in earthwork costs of 30 per cent. The large expenditure necessary for this plant has already been, mentioned. In addition, I might here state, in order to provide for unemployment, the number of men on construction-works generally has been very largely increased, with, the natural result that this year's expenditure exceeds last year's by over three millions. It may be as well to explain, however, that some of this expenditure will not be recurring. I refer particularly to the item " Additions to open lines," where an expenditure of £1,85(5,380 has occurred. This, however,

D.—l

represents principally a large purchase of rolling-stock to make up the shortage created during the war period. The Public Works Statement is primarily a report to Parliament of the operations of the past year, and a forecast of policy intentions of the ensuing year. It may, however, be of interest to honourable members if I take the opportunity of outlining, briefly, the achievement of the Department during the past ten years. During the period 1912-1922, £18,178,422 has been expended in public works. This amount does not include expenditure on additions to open lines, telegraph extension, immigration, workers' dwellings, or school buildings. For this sum we have had 235 miles 18 chains of railway completed and handed over to the Working Railways Department, while between forty and fifty miles have been brought to the stage of being used for public traffic under the direction of the Public Works Department, although not yet handed over. In addition, there is a very large mileage of formation over which, there is not yet traffic. Practically the whole of the hydro-electric work of the Department has been done since April, 1912. This includes the ultimate development of 16,000 horsepower at Coleridge, where very shortly there will be an actual development of 12,000 horse-power. The headworks for the whole 1(5,000 have been completed, and the reticulation for the disposal of the whole practically completed. In addition, the Government has purchased the Horahora power-station of 8,000 horse-power', constructed transmission-lines permitting the sale of the whole output, and has in hand the extension of both power-house and headworks. The preliminary development of 1,000 horse-power at Lake Waikaremoana has been constructed and will shortly be in commission. The development of 24,000 horsepower to supply Wellington and surrounding districts from Mangahao is in hand. These works have been vigorously prosecuted during the last two years. The constructional works necessary at Mangahao are very considerable, consisting of over two miles and a half of tunnel, three large concrete dams, three-quarters of a. mile of pressure pipe-line —part double and part quadruple— together with the necessary power-house, &c. The whole of this work is well advanced. A considerable amount of the material necessary for the hundreds of miles of transmission-fines is in hand, and erection has commenced. Complete surveys for the duplication of Lake Coleridge, and for development at Hawea-Wanaka, Teviot, Gowan, Aratiatia, Arapuni, and Hutt Rivers have been carried out. The detail plans in connection with Arapuni are well advanced, and an arrangement has already been made for the sale of a large portion of the power when available. Local-body proposals have been investigated, and approved or disapproved as circumstances required. An immense amount of roadwork has been carried out. Over 5,100 miles of road have been formed, and over 2,500 miles metalled. On these roads—not including small bridges and culverts — a length of 111,881 ft., or over twentyone miles, of bridges have been erected. Some of the bridges are of very considerable magnitude: three are between 950 ft. and I,oooft. long, two are 1,200 ft., while twenty-four are over 300 ft. Irrigation works involving over one hundred miles of water-races, sonic; of very large capacity, have been constructed. A number of concrete; dams were built. One of these is over 100 ft. high and holds 1,800,000,000 cubic; feet of water, enabling the irrigation of 20,000 acres of land to be effected. Other schemes, providing for the irrigation of many thousands of acres, have been investigated, and for some the survey is completed. During the whole of the war period, and since, the erection of public buildings has been deferred to as great an extent as possible, but nevertheless 283 Government buildings of various classes have been erected, including 131 post-offices. Irrigation provision, like hydro-electricity supply, is a matter upon which educational effort is necessary, even to the extent, in the general public interest, of undertakings which, for the time being, do not completely pay their way. Irrigation works are of a peculiar nature. They are very similar to development roads in that they enable settlement to take place and production to be effected, which would be impossible without the water-supply which they provide. It is, of course, desirable that in addition to paying their way they should also provide interest and sinking fund, but in this respect the call for repayment of interest should not be so strong as in the case of hydro-electric undertakings. If electric power is

D.—l

required and is not produced by hydraulic agency it can be produced in some other way, and the industry for which the power is required can still go on ; but in the case of irrigation works, if the water is not supplied, nothing can take its place, and land which might carry from three to five sheep to the acre must remain, tussocky waste, carrying less than one-tenth part of the stock ; and crops which can be grown most luxuriantly with water cannot be raised at all without it. For every acre irrigated the State as a whole gains in many ways. Although the total number of sheep in the dry counties surrounding the irrigated area decreased between 1914 and 1922 the numbers carried by the irrigated area actually doubled, the increase being progressive and keeping pace with the increasing sale of water. The increase in irrigation receipts ever since irrigation water was first made available has been sustained, and this year I am glad to say that there has been a substantial surplus of receipts over working-expenses and maintenance costs. But more has yet to be earned—and it can be earned —to recoup the State for its expenditure. EXPENDITURE. The total net expenditure under all votes and accounts appearing on the public-works estimates for the financial year ended 31st March, 1922, was £6,922,039. Of this sum £5,280,087 was expended out of the Public Works Fund, and the balance, £1,035,352, out of accounts which have their own ways and means and are quite separate from the Public Works Fund. A brief summary of this expenditure, as well as the total expenditure since the inception of the public-works policy to the 31st March last, is shown below in tabular form :—

RAILWAY-CONSTRUCTION. Only one section of completed railway (Clyde to Cromwell, 12 miles 34 chains in length) was handed over to the New Zealand Railways Department during the year, although other sections were in a sufficiently advanced state to permit of a goods and passenger service being maintained by my Department. The Mount-Matata Section, 40 miles in length, has been completed for several years, but owing to its isolation has not been taken over by the New Zealand. Railways Department. A regular service under Working Railways conditions, however, is in operation. The net expenditure on construction, maintenacc, and supervision for the financial year was £3,265,440, as follows : —• £ Construction, improvement, and maintenance of new lines 1,276,820 Additions to open new lines (rolling-stock, locomotives, &c.) 1,856,380 Railways Improvement Authorization Act 1914 Account . . 132,240 Total .. .. .. £3,265,440 * The following is a brief description of the work carried out during the year on the principal lines : — Kaihu Railway Extension. Formation, except a small portion of road approaches at Aranga and Donnelly's, is complete. Platelaying on the main line and at Aranga and Donnelly's stationyards has been finished. The final lifts of ballast have been completed except at the two station-yards. It is anticipated that this section, will be handed over this year. The concrete piers and abutments of the bridge at Donnelly's station-yard have been finished, and the steel girders erected. The bridges at 21 miles 24 chains and 22 miles 65 chains will be completed shortly. Passenger platforms and loading-banks have been constructed, cottage-sites cleared, and approaches made. Tenders will shortly be invited for the erection of station buildings and cottages, the Department supplying the timber from its mill at Whatoro. This section will be ready to transfer to the New Zealand Railways on completion of the bridges at 21 miles 24 chains and 22 miles 65 chains. Whangarei Branch. Oakleiqh Section. —The deviation at 7 miles 15 chains has been completed and the rails on either side connected. Ballasting has been finished and efficiently maintained. A temporary connection from the main line to the Portland Cement Company's quarry line has been used to enable cement - supplies being loaded direct into the Department's wagons. Tauraroa Section. —Work has been confined chiefly to removal of slips and maintenance. One large embankment at 9 miles 75 chains gave considerable trouble through subsidence, which necessitated drainage drives to reach the seat of trouble. The output of the Tauraroa crushing plant was over 21,000 yards. To provide increased quantities of ballast for the Main Trunk connection an auxiliary crusher has been installed, and fresh tenders have been invited for the further supply of stone for crushing purposes. Waiotira Section. —I referred in my last Statement to the treacherous nature of the country traversed by this line, and two deviations have been made to avoid dangerous ground. These deviations have proved satisfactory. A drainage drive was constructed in the bank at 17 miles 10 chains, which has prevented further subsidences. Throughout the whole section large drains are being made in the cuttings, pipes laid in them and covered with boulders to facilitate drainage and prevent upheaval of the line. The toes of slopes that slip will be protected with stone walls. It is confidently expected the line will become stablized by the end of the approaching summer. Platelaying on the deviations above referred to completes the linking-in of the main line from Portland to Waiotira.

D.—l

VII

The Tie tamping-machine has been used on this line with marked success. The ballast is tamped quickly, tightly, and evenly, thereby producing an even running-track, and minimizing the cost of maintenance —which has hitherto involved heavy and constant expenditure when hand-packed. A contract has been let for the girder spans of bridges from Portland to Waiotira. The goods traffic has been exceptionally heavy from Portland (cement and coal) and from Oakleigh, where a wharf gang had to be constantly employed discharging and loading cargo. Most of the traffic was in connection with the Main Trunk Railway, but the goods and produce of trades-people and settlers were carried. A passenger service has now been inaugurated, and is increasing to an extent necessitating additional carriages. It is anticipated that this class of traffic will still further' develop during the coming summer. Waipu Branch. Ruakaka and Waipu Sections. —The principal work on the former section consisted of formation over the mud-flats, about a mile of which is now complete. One steam-shovel was engaged continuously excavating from a borrow-pit. No work' was done on the Waipu Section. North Auckland Main Trunk. Huarau Northwards. Paparewa Section. —Second and third lifts of ballast have been placed on the main line throughout, which completes this section, with the exception of platelaying, ballasting, and buildings in Paparoa station-yard, clearing up northern approach cutting to Huarau Tunnel, and general cleaning-up. Mareretu Section. —Workmen were concentrated on this section during the year, and considerable progress was made. Fifty horses were transferred from the Whangarei end for plough and scoop work, with excellent results. Enlarging and lining Golden Stairs Tunnel (south end) was commenced last July, the position now being that 12| chains of lining are completed. Work was delayed during the months of October and November by a strike of workmen for higher rates of pay. During this suspension of work the " Chicago " compressor plant was extensively overhauled and repaired. Both plant and men are now working satisfactorily, and during the last three Jmonths|4£ chains of lining has been completed. At the north end a commencement was made in October with the bottom heading. Lining, however, was delayed till January of this year as a result of difficulty in procuring experienced men. A subsidence in the first length caused further delay. Working-conditions at both ends of this tunnel are good. The men appear to be contented, and at the present rate of progress the remaining 11-| chains of lining should be finished by the end of November. Only 5 chains now separate the bottom heading faces. During the year a second and third lift of ballast was laid over the whole length from Paparoa station-yard to Golden Stairs. The Mareretu Section is well in hand and should be ready for service about February next. Waikielcie Section. —Suitable labour was concentrated on the erection of Mangawai River Bridge. Considerable difficulty was experienced with pile-driving on account of the soft ground, which necessitated pile cradling and splicing : this portion of the construction, however, is practically finished. Temporary staging and other preliminary work has been done in connection with Kikowhiti Bridge erection, and pile-driving is being commenced. This bridge should be completed in three months. Between 102 miles 48 chains and 103 miles 9 chains a deviation had to be made, as practically the whole locality was slipping, so much so that large cuttings were completely filled. The Waiotira station-yard was completed with two steamshovels, which excavated 30,000 cubic yards to make up the required filling. The Mareretu Tunnel was completed last April, 13| chains having been lined during the year and one portal built. Owing to the treacherous nature of the

D.—l

VIII

ground, heavy, closely-placed timbering was necessary for the entire length, and the complete section was encased in concrete. It was only by vigorously pushing on the excavation, followed closely by the concrete lining, that construction was at all practicable. About three miles of temporary line has been removed and replaced with permanent rails, and a commencement made with laying the sidings in Waiotira station-yard. It is anticipated that the permanent rails will reach Kikowhiti Bridge by the end of the year ; and by March, 1923, rail connection should be established between Whangarei and Auckland. Ballasting (first and second lifts) is proceeding at a rapid pace. Both passenger and goods traffic has been heavy over the length north of Mareretu Tunnel, and it will increase in volume as the permanent rails are extended southward, especially when through connection has been established with Auckland. Kirikopuni Section. —Operations have been confined to the northern end of this section. A temporary tram-line has been laid from the Wairoa River to Omana Tunnel. The northern approach to this tunnel has been opened, but owing to the treacherous nature of the country it was impossible to commence driving in the usual way, and three lengths of reinforced-ooncrete section-lining had to be built at the entrance. It is proposed to construct a jig-line over the tunnel hill for the transport of material for driving operations at the southern end. Kaikohe Northwards, Okaihau Section. —Slips on this line have caused trouble, but I am pleased to say that the measures taken to cope with these have proved effective. Rails are being laid in Okaihau station-yard. Goods traffic has been commenced, and within a few weeks it is intended to commence a passenger service, which will be a great benefit, particularly to Hokianga residents. Mails will also be carried between Kaikohe and Okaihau. A concrete water-reservoir has been commenced at Okaihau, and it is hoped to have yards erected before November next, to facilitate the transport of sheep and cattle from Hokianga to the freezing-works at Moerewa. Waiuku Branch. Both sections of this line have been finally completed and transferred to the New Zealand Railways Department for regular traffic purposes. HITNTLY-AWAROA. Steady progress has been made with this line. Formation, bridge and culvert construction, drain-cutting, and access-road formation are in hand from 7 miles 20 chains to 9 miles. The earthworks on this line are heavy. The nature of the material to be excavated renders it economically necessary to employ large plant, and three steam-shovels have been installed. Considering the difficulties to be overcome good progress has been made. It is proposed to let a contract for the Summit cutting to the owners of the coal-mines at the terminus of the line. The advantage of this is that material from the cutting will be used for the special mine sidings. Waikokowai Branch. A contract has been let for the land-plan survey of this railway, and this should be completed shortly. East Coast Main Trunk Railway. Waihi-Taneatua (including Mount Branch). Athenree Section. —Formation is practically complete. Several cuttings and banks having been completed. Athenree station-yard has been widened, and filling around abutment "A" of Mangatoetoe Bridge is in hand. Seven bridges are in various stages of construction. Adams Street subway is well advanced, and subway at 8 miles 62 chains has been completed.

D.—l

Katikati Section. —Formation, culvert-building, line clearing and fencing have proceeded steadily along several miles of this section. Permanent survey has been completed to the Wairoa River, and plans are in course of preparation. Tauranga Westwards.- —Work on this section was practically suspended last February. One overbridge was completed. Another similar structure, including the approach and the road to Tauranga Railway-station, are in hand. Matapeihi Section. —Satisfactory progress has been made with the Tauranga Harbour Bridge. The completed work during the year consisted of concreting and reinforcing 106 lineal feet of cylinders, 155 ft. of cylinder-sinking, while six piers were sealed and are in readiness for filling in. Cylinder L has been filled in, and core-rods placed in position. The Matapeihi embankment was completed, and a loading-platform erected for delivery of stone for the Tauranga waterfront works. Mount-Matata Section. —Several banks have sunk, but have been efficiently maintained throughout the year. The passenger and goods railway service has been continued. Rangitaiki Section. —Cuttings have been widened, over a mile of drains cut, and the approach road to the Rangitaiki Station put in. hand. Three steamshovels were in operation at different times at Awakaponga, the spoil being deposited in the several banks along the line. Many culverts have been built, and one bridge completed. Awakeri Section. —Little work has been undertaken on this line, except 15 chains of drain-cutting and about 2 miles of fencing. Taneatua Section. —lo6 chains of formation have been completed during the year, culverts erected, and necessary drains cut. A " Marion " steam-shovel commenced work in May last, and an " Osgood" is in course of erection. A departmental telephone-line 5 miles long was erected, and a small amount of platelaying done. The rail-head is now 52 miles from Tauranga. Mount Workshop. —A large quantity of material for use in the erection of the Tauranga Bridge has been prepared, consisting of cylinder core-rods, reinforcing for piers, transoms (straight and curved), extension stringers; sway and diagonal bracing, cutting and drilling top chord and wind-brace gussets and cover and stiffening plates, The fabrication of structural steel for numerous bridges throughout the Dominion as well as the structural steel for boiler and engine roof-trusses for Otira power-houses have been completed. Gisborne-Napier Railway. Eskdale Section. —The river gap at 0 miles 32 chains still remains to be filled ; in the meantime a temporary bridge has been provided to allow platelaying to proceed. The Harbour Board has completed the filling on the main line at 0 miles 55 chains, but still has the completion of the port line to attend to. Both this and the gap at 0 miles 32 chains are dependent upon the completion of the river-channel by the Harbour Board. Platelaying was commenced and completed almost to the Westshore stationyard, and it is anticipated that the rails will reach Petane in October. Two more platelayers' cottages of concrete blocks have been erected, and the Stationmaster's house in similar material is almost complete. Platform and loading-banks have been finished at Eskdale station-yard. Tutira Section. —Fair progress has been made in various cuttings, especially where the " Thew " steam-shovel has operated. Formation is now practically complete to 14 miles 47 chains. Concrete piles for the bridges at 11 miles 41 chains and 13 miles 35 chains have been made, and abutment D at the former has been completed. Ngatapa Section. —A passenger and goods service has been operated during the year. The Ngatapa station-yard and formation (where necessary) have been raised above flood-level. The formation at Repongaere station-yard was brought up to correct level. Bridges have been maintained, culverts lengthened, and the third lift of ballast spread from 9 miles 40 chains to Ngatapa Station. The Waipaoa ballast-pit line has been taken up and shipped to Wairoa.

ii-D. 1.

D.—l

Waikura Section. —The cutting at 11 miles 65 chains gave much trouble by slipping. The slips, however, have been removed and used for raising Ngatapa station-yard above flood-level. Several cuttings have been completed, and formation is now roughly complete to 13 miles. Rails are laid to 11 miles 55 chains, the first lift of ballast to 11 miles 50 chains, the second lift to 10 miles 60 chains, and the third to 10 miles 45 chains. A "Marion" steam-shovel has been worked between 11 miles 65 chains and 11 miles 75 chains throughout the year. Wairoa- Waikokopu. Nuhaka Section. —The formation over the whole section is sufficiently completed to admit of rails being laid throughout. Three miles of rails have been laid at the Wairoa end, and a .further 50 chains of wharf-siding to the Wairoa River. Platelaying-material was unloaded at Waikokopu Harbour and carted to Nuhaka, where permanent rails were laid from 17 miles 47 chains back to 13 miles 62 chains. A line to ballast-pit near the 15-mile peg has been laid. From this pit practically all the ballast for this line will have to be obtained. A Stationmaster's and three platelayers' cottages have been erected at Wairoa, and two platelayers' cottages at Nuhaka. Waikokopu Section. —-The heavy formation from Nuhaka to Waikokopu has been steadily pushed forward despite the very unfavourable weather experienced. It is anticipated the formation will be sufficiently advanced to admit of rails being laid right through by January next. A large number of men are employed, and some of the cuttings are being worked with double shifts to expedite completion. Three steam-shovels are now in operation on this line. Stratford - Main Trunk. Matiere Section. —Platelaying was commenced in November last, and on the 23rd May of this year the line, 10 miles 23 chains in length, was formally opened for goods and passenger traffic under my Department's control. One lift of ballast has been laid over the whole length, and a commencement made with the second. The Ongarue combined bridge was finally completed during the year. It consists of two decks : the upper, which carries the railway, has two central 60 ft. trusses, outflanked by one 45 ft. and one 25 ft. steel-plate girder at each end. The lower or vehicular-traffic deck is carried on the bottom chords of two 60 ft. trusses. The concrete-work on three of the Ohura River bridges has been completed, and temporary superstructures have been provided to carry the traffic;. The fourth Ohura crossing is provided with a temporary structure to carry the traffic. The excavation for foundations of the permanent piers for this bridge has been commenced. The steelwork for these four bridges is being prepared in the Mount Workshops, Tauranga. Two subways have been completed, one to give access for a sawmill tramway, and the other for the Otahu access road. The principal work remaining to be done comprises completion of ballasting, finishing bridges, Tuh.ua and Matiere station-yards, and the necessary buildings at these two stations. Ohura Section. —Formation-work on this length is now being opened up. Tahora Section. —All earthwork formation and platelaying has been completed. At Tahora Station a water-service has been installed, shelter and goods sheds erected, and station-platform and loading-bank built. The main Ohura Road, which is used as a service road, has been efficiently maintained. A bi-weekly passenger and goods service has been run between Kohuratahi and Tahora, connecting with New Zealand Railway service at Kohuratahi. Te Wera Quarry. —A branch line, 1 mile 16 chains in length, connecting with the Stratford -Main Trunk Railway at 22 miles 63 chains, has been constructed. Stripping has been commenced, and 50,000 yards of rock is ready for excavation. The crusher has been erected, and as soon as the bins, which are in course of erection, are complete, crushing operations will proceed. Suitable accommodation has been erected to meet the needs of all employees.

D.—l

Opunake Branch. Kapuni Section. —The formation, with the exception of a little widening and easing batters, is fully ready for platelaying. This latter work has been commenced, and 34 chains of rails laid. Platelaying will now proceed uninterruptedly except for the time required for launching girders on Mangatoki and Kapuni bridges. A steam-shovel has been employed stripping ballast-pit at Kaupokonui River, and 18,000 yards of stripping removed. A goods-shed has been erected at Kapuni Station. Auroa Section. —Work has been confined primarily to fencing (which is complete except for flood-gates), culverting, and earthwork, including excavation of Auroa station-yard, which is nearing completion. Pihama Section. —About a mile of formation has been finished, the remaining culverting is in hand, and clearing, including logging and stumping, has been finished to 14 miles 60 chains. A concrete-block platelayer's cottage has been erected in Pihama station-yard at 16 miles 40 chains. Opunake Section. —This section has only just been commenced, the work done being of the usual preliminary character —viz., erecting camps, clearing, carting shingle, draining, besides a little formation. Manaia Section. —The only work done on this branch was completion of cutting at 3 miles, the erection of gates at private crossings, and general maintenance. Midland. Glenh ope-Murchison. Kaivatiri Section. —Tunnel at 62 miles 43 chains. A commencement was made in November with one shift, and 246 ft. of bottom, heading has been driven. The material encountered is hard granite, broken with seams of quartz, winch has made both drilling and shooting difficult. The piers for Hope River Bridge have been completed, and the four girders have been erected for field riveting. The temporary bridge was seriously damaged by flood in March last, but it has been restored to the level of concrete piers and is ready for the launching of girders. Otira-Beoley. This section, extends from Arthur's Pass Station, the present railway terminus on the Canterbury side of the pass, to Otira Station, the present railway terminus on the Westland side. The section is only 8 miles 54 chains long, but includes the Arthur's Pass or Otira Tunnel, of 5 miles 25 chains in length, and nearly the whole length of the section is on a grade of 1 in 33, the summit of the line being 1,177 ft. above the Otira Station and 2,436 ft. above sea-level. The lining of the tunnel was completed in October, and the floor has now been cleaned up and the permanent 100 lb. track laid from 5.1 miles 54 chains to 58 miles 40 chains, with the exception of about 10 chains across the Rolleston Bridge. The dismantling of buildings and plant required in the tunnelling operations has commenced, and portions of the plant transferred for use on other works. A crushing plant, with two crushers and a steam - navvy, was installed at Arthur's Pass, and with this and the aid of a small crusher at Otira the line has been ballasted and. lifted with the first lift from 5.1 miles 54 chains to 58 miles 12 chains. Arthur's Pass Station-yard. —The formation was completed, and a start made with the concrete kerbing for the platform, and excavation for the subway. A permanent water-supply for railway and village requirements has been located. Bealey Bridge. —This bridge is immediately at the Canterbury portal of the tunnel. It is a skewed structure, and includes vertical and horizontal curves in the track. The permanent superstructure, comprising about 230 tons of structural steel, has been delivered at site, and six of the girders riveted up ready to be placed on the piers. Electrical Equipment. —-The steam-power station located at Otira has been erected in reinforced concrete, and the associated workshops, electric-locomotive sheds, and coal-bunkers are nearing completion. Overhead electric cranes are being installed in the main engine-room, workshop, and over the coal-bunkers.

The boiler equipment comprises three Babcock and Wilcox marine-type boilers, specially arranged to meet the conditions of load that will exist. A large quantity of the material has arrived and is in course of erection. Of the engine-room equipment two steam electric generating sets of 100 kilowatts capacity have been erected, with condenser, also the condensers for the main traction turbo-generating sets. A quantity of switch-gear and piping is on the site. The main turbo-generators will supply electrical energy to the locomotives at 1,500 volts, and the first of the two sets was shipped from England early in. June, the second set beiag then in an advanced state of erection at the makers' works. The five main-line electric locomotives are in various stages of completion at the Dick-Kerr works of the English Electric Company. The motors and controlgear have undergone satisfactory tests, and the final assembly of the first two locomotives is nearing completion. Inangahua Junction. —The condition of the Inangahua Junction Traffic-bridge is such that rebuilding is essential. It is proposed, therefore, to make provision enabling the combined road and railway bridge to be put in hand immediately. In connection with the overhead equipment of the line, the contractors have installed feeder cables throughout the tunnel, involving the erection of 6,000 castiron racks, and arrangements for erecting the poles outside the tunnel are in hand. The wiring of the tunnel for electric lighting has been completed. Some 1,500 railjoints have been bonded. The shipment of boilers and electrical machinery has been seriously delayed by the widespread lockout in the engineering industry in Great Britain. Water-supply. —The development of Goat Creek for the supply of condensing water at Otira has been undertaken and pipes ordered. To provide sufficient water for condensing purposes and for' operating air-pumps, two storage reservoirs have been provided in the designs, and excavation for these is nearing completion. The pipe-line has been cleared and a road formed to the intake. The intake dam across Goat Creek has been concreted. Village. —A site for some forty-three cottages has been, prepared at Otira., and fourteen are in course of erection. At Arthur's Pass the sites for eighteen cottages have been cleared, and excavation carried out for sixteen. It is hoped to have trial runs by the end of the year, and if these prove satisfactory general traffic will be carried. Greymouth - Point Elizabeth. Platelaying has been completed to 5 miles 69 chains, and about three-quarters of a, mile of sidings linked up. First and second lifts of ballast have been placed from 3 miles 46 chains to 5 miles 68 chains. Necessary side drains have been cut and culverts built. A temporary bridge over the Seven-mile Creek has been erected. Excavation for a 25,000-gallon reservoir is complete. Water-race has been graded and suspension rope swung across Rocky Creek to carry the water-pipes. Orepuki—Waiau. Orawia Section. —Work has steadily proceeded, and the formation, with the exception of two cuttings which are well advanced, is complete throughout. It is proposed to proceed at once with platelaying and ballasting. Lawrence-Roxburgh. Formation-is more or less complete over the first 4 miles, except in cuttings which have been left narrow, as the balance of widening can be more expeditiously carried out when the construction-train is available for removal of spoil. The Beaumont Creek Bridge is in hand, abutments A and E are complete, and pier D finished to hand-holes. Rails have been laid to this bridge, and will proceed beyond after its completion.

Surveys. Rimutaka Deviation. —Work on the various trial surveys in connection with the Rimutaka deviation is nearing completion. The surveys of the Tauherenikau and Coach Road routes have been completed, and plans and estimates are being prepared. The party is now being moved to complete the survey of the Wainuiomata route, work on which was suspended during the war. Tuapeka Mouth Branch Railway.— During the year the various trial surveys for the above railway were completed. Three routes were surveyed, as follows : (1) Crichton to Tuapeka Mouth via Hillend. ; (2) Lovell's Flat to Tuapeka Mouth via Lovell's Creek and Hillend ; and (3) Lovell's Flat to Tuapeka Mouth via Stony Creek and Hillend. A fourth route, running from Sterling to Tuapeka Mouth, and known as the Riverbank route, was surveyed some years ago. Plans and estimates for all these routes have been prepared and reports submitted. Plans have also been forwarded to the Agriculture and Railways Departments for investigation and report. Dunback-Kokonga Railway.- —A reconnaissance survey of this suggested railway was made during the year, and approximate estimates prepared. Plant. In the last Statement I said something about the installation of a large quantity of machinery on' the works and. about the beneficial results obtained. 1 am pleased to be able to announce that the results of last year's work with the plant have been highly satisfactory, and have more than justified the outlay involved. The class of machinery most beneficial on our public work is that in connection with the excavation and transport of earthwork, and in this direction our plant has not only speeded up the rate of work, which was to be expected, but it has also considerably reduced the cost, a result not always so easily attained. The excavating machinery consists chiefly of steam-shovels and drag-line excavators for heavy earthwork, and scoops, hauled by caterpillar tractors, for the lighter work. Thirty-four steam-shovels and drag-lines are now at work, and an indication of their economy is provided in the fact that the average cost of excavation by these shovels during the last year has been 2s. 3d. per cubic yard, whereas the cost by hand would undoubtedly have been 30 per cent, higher. This rate, of course, includes haulage, which has chiefly been done by small construction locomotives, which attend almost every steam-shovel. The equipment necessary for excavation by a steam-shovel, consisting as it does of a locomotive, a large number of trucks to cope with the increased output, and appliances for tipping trucks and spreading material, is in many cases more expensive than the steam-shovels themselves. Success and economy have also been achieved in transporting material from steam-shovels by means of caterpillar tractors hauling rakes of trailers. The excavation-costs of drag-line machines have been so satisfactory that I have considered myself justified in purchasing from England this year two machines of a much larger type than any yet used in this country, and I am hoping to have these in operation early next year. The metalling of roads presents one of our most difficult problems, and one in which there is considerable economy to be obtained by using modern appliances. The actual crushing of the road-metal is the part of the problem most easily solved, and a large number of modern stone-crushing and screening plants installed now for some years have economically settled this point. The haulage of road-metal is, however, a more serious matter, and one whereby a great deal of money can be wasted. The solution so far seems to have been the use of the motor-lorry, and therefore the Department has invested in a considerable number of these for the purpose. This service has resulted in a considerable saving over the old methods of haulage, and has enabled lengths of road to be metalled on which the cost would have been almost prohibitive by any other means, chiefly on account of the distances over which the haulage was necessary. The Department is now constantly on the lookout for machines that will accelerate and consequently cheapen the rate of work, and, in addition to the above examples, much advance has been made in regard to tunnelling and concreting machinery used. It is now recognized that machinery sets the pace and speeds up construction, especially when concentrated.

It must be remembered that any reduction in the time of the completion of a work by the use of better appliances results in a shorter period in which capital lies idle, and therefore in a reduction of interest and overhead charges. Very often I know it can be shown that machinery has not actually reduced, and has even sometimes increased, the construction-costs of a work, but investigation would show that the saving in interest and overhead charges on idle capital has compensated many times over for the use of the plant. I am pleased to say that none of the larger works in this country have as yet shown an increase in construction-costs by the use of larger plant, but even had it been so I would consider myself quite justified in its use if I were satisfied I could save eventually by a reduction of interest and overhead charges. Railways Improvement Authorization Act, 1914. The expenditure under this Act amounted to £132,241, for grade easements, formation of new line signalling interlocking and safety appliances, new station and station-yards, goods-sheds, and terminal facilities at Auckland, Wellington, and Addington. Additions to Open Lines. The expenditure out of the Public Works Fund under the head "Additions to open lines" amounted to £1,856,380. Of this sum £1,121,132 was expended in the provision of additional rolling-stock, tarpaulins, Westinghouse brakes, workshops machinery, and steam heating. The balance covered expenditure upon improvements to engine-depots, workshops, station facilities, water-services, additional dwelling for the staff, signal, tablet, telegraph and telephone installation, bridge-work, subways, and purchase of land. PUBLIC BUILDINGS. General. Parliament Buildings, Wellington. —A large amount of work was carried out in this building during the year, and was finally completed in time for the opening of Parliament. The most important portion was the "working and setting of the ornamental -marble for the interior finish of the main lobbies, together with the marble tiling and the general finishing-work. A particular feature of the finishingwork was the Cabinet-room. This has been panelled in Canadian walnut and birdseye maple, the timber being supplied by the Canadian Government as a gift to the New Zealand Government, the working-up and finishing being carried out in the Department's local workshops. Departmental Buildings. Auckland (Stamp Office). —An additional story in brick was erected, and alterations carried out to provide additional accommodation for both the Deeds and Stamp Departments. Wanganui. —The Wangauui Native Land Court building, which was commenced last year, has been completed. It is of brick with plaster finish inside and out, and comprises Court-room, offices, strong-rooms, and outbuildings. Courthouses. New Courthouses were erected at Waipukurau and Pukekohe. With these exceptions, only essential repairs and maintenance were carried out. Prisons. Prison - building operations were limited to the completion of partially constructed buildings, and the provision of purely essential accommodation. Three cottages for married officers were completed on the Auckland Prison Reserve, and also a shelter-shed for the prisoners in the quarry. At Waikeria Reformatory, quarters for the single officers have been completed and are now in occupation.

D.—l

Inmates of this institution were employed clearing and bringing into cultivation a block of land on the Tokanui Mental Hospital Reserve. Roadmaking and sawmilling have been pushed on at the Waikune Camp, Erua, and considerable quantities of timber have been supplied for public works during the year. The new Hoffman brick-kiln at Wi Tako Prison, Trentham, has been completed, and bricks in large quantities are now being turned out. The construction of the second cell-range and kitchen block at Paparua has progressed satisfactorily, the kitchen block being now in occupation and the cell-range well advanced. The new kitchen block at the Borstal Institution is now approaching completion, and two additional cottages have been built for married officers. . Police-stations. Expenditure was restricted practically to the completion of works for which contracts had already been entered, into, the purchase of a few properties in cases where there were no other means of obtaining accommodation, and essential maintenance. New police-stations were erected at Bull's and Waikari, and a sergeant's residence at Mount Cook (Wellington) ; the new police-station at Dannevirke and. sergeant's residence at Palmerston North were completed,; additions and improvements were made at Seddon Police-station ; and the police buildings at Karangahake were removed and re-erected at Matamata. Alterations and improvements were made to the properties which had been purchased during the previous year at Green Island, St. Kilda, Port Chalmers, Woodhaugh, and Ravensbourne. Houses for use as police-stations were purchased at Whataupoko, Takapau, North Invercargill, Tuatapere, and Winton. New police buildings are required at a number of places where the existing buildings, many of which were erected over forty years ago, havQ become almost unfit for habitation, and also where the Department has at present to rent unsuitable properties at high rentals. Provision for the erection.of police-stations at such places is being made on the current year's estimates, with a view to the works being proceeded with as soon as financial circumstances permit. Post and Telegraph Buildings. Plans are in course of preparation for a number of post-office buildings, the erection of which will be proceeded with when finances permit. During the year departmental buildings were erected, or the erection completed, at Alexandra, Amberley (line foreman's residence), Aria, Chatham Islands (Superintendent's residence), Devonport (automatic telephone-exchange building), Fitzroy, Carston, Henderson, Hororata, Lumsden, Manurewa, Matawai, Nightcaps, Onehunga (automatic telephone exchange), Papanu , Paraparaumu, Ranfurly, Rangiotu, Rockviile, Tapawera, Taupiri, Te Kopuru, Waiotemarama, Whakahoro. Alterations rendered necessary by growth of business were carried out at Chatham Islands (radio-station), Dunedin, Hawera, Morrinsville, and Timaru. The old post-office building at Port Nelson was removed to Stoke, where it was refitted for use as a post-office. Small buildings were purchased at Cave, May field, and Mokauiti, and adapted for use as post-offices ; also at Glen Orua, where the old building had become unsuitable for use as a post-office. Mental Hospitals. Additions in brick to auxiliary No. 2 female ward at the Auckland Mental Hospital, to accommodate eighty patients, were completed. Minor repair and maintenance works have been carried out at the Avondale Mental Hospital, and a new roof put on part of the Wolff Home. The Tokanui Mental Hospital male admission block, with pressed bricks and rough-cast walls, was completed, giving accommodation for approximately twenty patients. At Nelson a new reception block in brick was recently completed.

Extensive additions to provide for kitchen, bakehouse, workshop, store, staff dining-room, billiard-room, and nurses' quarters are being carried out by day labour at Hokitika Mental Hospital, while the usual maintenance-work has been attended to. Maintenance-work has been carried out at Seacliff, and a new unit has been completed at Waitati. A day-room extension has been erected on the women's side of the main building at Sunnyside. At Hornby the alterations and additions have been completed. Hospitals and Charitable Institutions. Among the works carried out during the year was the renovation and improvement of military hospitals taken over by the Health Department from the Defence. A very considerable amount of this renovation-work, however, had to be postponed owing to financial circumstances, but must be proceeded with as soon as funds will permit. The St. Helens Hospital accommodation, recently erected at Auckland, and which is almost internally completed, is of brick and provides for thirty-seven beds, together with all facilities and requirements for carrying out the functions required in a modern maternity hospital. Similar accommodation is required in Christchurch, and as soon as finances will permit this important work Will be taken in hand. In the meantime the present buildings have been put in repair, and additional accommodation has been provided for the nurses. Education. During the past financial year the expenditure on educational buildings was £565,670 —£563,201 from the Education Loans Account, and £2,469 from the Public Works Fund, the latter amount being expenditure not provided for by the Education Purposes Loans Act, 1919. This expenditure exceeded by over £100,000 that for the previous year, which was at that time a record. The large expenditure was owing to the fact that during war-time the amount approved for the erection of educational buildings was reduced to a minimum, and after the war closed very substantial grants were approved to overtake the arrears of urgent works, the cost of which had greatly increased. So difficult was it, however, to obtain the necessary labour and materials that there was considerable delay in carrying out the work, and consequently much of the expenditure during the past year had reference to authorities given during previous financial years. In this connection it may be pointed out that, while at the end of the financial year 1920-21 the unexpended commitments were £825,661, at the end of the last financial year the amount was only £366,766. Of the total expenditure for last year £328,228 was for primary schoo s, £101,199 for technical-school buildings, £81,197 for secondary schools, and £39,071 for University buildings. Circumstances, however, necessitated a considerable curtailment of sums approved for new buildings, and the total new grants for the year were only £105,424, as against £724,902 for the previous year. Grants were confined to cases of the greatest urgency, and were made as far as possible for actual school accommodation, chiefly in backblock districts. Wherever possible, temporary accommodation in the form of rented buildings is being utilized in lieu of providing permanent buildings. At the close of the year there were before the Department applications amounting, under all heads, to £600,376, of which £461,403 had reference to public schools. The urgent necessity of providing funds for the many pressing requirements is fully recognized, and it is hoped, in the not-far-distant future, to revert to the progressive building policy initiated a few years ago. Lighthouses. Owing to the site of the East Cape Lighthouse at East Island having become dangerous, it was decided to transfer the lighthouse to the mainland. Its removal was undertaken during the latter part of the year, and its re-erection on the mainland is nearing completion.

D.—l

XVII

An automatic light was erected on Ninepins Rock early in the year, and first exhibited on the 30th August, and has proved very useful to navigation. Two new cottages for keepers were erected at Cape Campbell, two at Cape Maria van Diemen, and one at Pouto, Kaipara, the old structures having become uninhabitable. It is intended to proceed with the erection of automatic lights on Gable End Foreland and Mercury Island as soon as the Department's lighthouse expert is available. Arrangements are being made for the installation of an oil-engine hoist for hauling goods from the landing to the lighthouse on Stephen Island in place of the present wooden whims, which are out of repair and unsuitable. HARBOUR-WORKS. All the buoys and beacons in the harbours under the control of the Department have been regularly overhauled, cleaned, and painted, and, where necessary, new moorings have been put down. TOURIST AND HEALTH RESORTS. No new works of magnitude were undertaken, but considerable improvements and additions were effected. At Rotorua wooden water-mains are being replaced by cast-iron ones, and a stand-by plant and extensions to the electrical system are in hand. Other works carried out were the erection of and improvement to residences at Rotorua, provision of " Crescent " gas lighting at the Hermitage, improvement and erection of huts at Tongariro National Park, construction of.a further section of the Grave-Talbot track from Wakatipu to Milford, the purchase of Sutherland's accommodation-house at Milford Sound, and the installation of telephonic communication on the Te Anau - Milford Track, whereby travellers are able to communicate direct from Milford to Glade House, Te Anau. The work of substituting iron for wood water-mains at Rotorua will be continued, as well as improvements at the various resorts. The necessity of the new massage building at Rotorua is recognized, and will be proceeded with when finances permit. ROAD CONSTRUCTION AND MAINTENANCE. The sum provided on the estimates for the year ending 31st March, 1922, for road and bridge construction and maintenance was less than for the previous year, but the expenditure has been greater —indeed, the heaviest on record for this class of work. With a view to increasing the general productivity of the Dominion, the expenditure has been confined principally to those roads that are at present the only means of communication to and throughout settled districts where railway facilities do not exist, and in the development of new districts. These activities have been mainly in the direction of formation of new roads, construction of bridges and culverts, metalling existing roads, and general maintenance. The works of greatest magnitude have been carried out by my Department, but local bodies have been entrusted with the execution of such undertakings as came within the scope of their capabilities. It is estimated there are at the present time approximately 50,000 miles of formed roads and bridle-tracks in the Dominion, of which 27,000 miles are metalled. It is further estimated that an additional 20,000 miles require to bo formed before the roading of the Dominion can be considered complete, even to an elementary standard. The desirability, and indeed the necessity, of roads of a sufficiently high standard to carry all classes of traffic become more apparent each year, and it is now generally recognized that this standard can only be attained by proper organization and modern equipment. The severe tests applied to road-surfaces by swiftly-moving and often heavy motor traffic have induced some local bodies to adopt a more modern and perma-

nent method of surfacing than mere metalling. The result of their experiences, lam informed, has demonstrated that it is more economical to adopt this system than incur the expense of costly repairs incidental to the previously existing systems of construction and maintenance. Much information has been collected by my Department regarding modern methods of main-highway construction, and other matters relating to the loading problem generally, all of which will be available for immediate use when the Highways Bill has been placed on the statute-book of the Dominion. The estimates for roads this year have been prepared as far as possible on a system of factors representing areas, populations, productivity, loans raised by local bodies, mileages of formed roads, amounts required for roads still to be formed and metalled, and values of Crown and Native lands still available for settlement, the last two of which are of the greatest importance when consideration is being given to the claims of the several districts. The construction and improvement of roads was jointly discussed by the District Engineers and the representatives of the various local bodies, and as far as practicable the allocation of the moneys available was mutually agreed to, and I desire to record my appreciation of the reasonable spirit shown by local bodies in recognizing the monetary limitations existing at the present time. During the past year the Department has continued, to as great an extent as possible, to avail itself of local-body organization for the expenditure of Government grants and subsidies. There has been a tremendous demand throughout the country for the.putting in hand of road and bridge works, but financial considerations have dictated the necessity of the selection of works of special merit for authorization, rather than a general authorization for all works, and although this has meant deferring many undertakings of considerable local importance the great majority of local bodies have adopted a helpful attitude and have materially assisted the Department through a difficult period. TELEGRAPH EXTENSION. During the year 106 miles of new telegraph and inter-urban telephone pole line, carrying 998 miles of wire, were erected. The telephone-exchange plant (subscribers' lines) was also considerably extended by the erection of 555 miles of pole line, carrying 5,271 miles of open aerial wire, and 63 miles of lead-covered cable, containing 15,110 miles of wire. The substantial increase over the figures of the previous year is due to supplies of material which had been under order for a considerable time becoming available. The telephone exchanges were increased by six during the year, while twentysix others are in various stages of completion. The number of new subscribers connected with telephone exchanges was 9,259, and this increase necessitated additional switchboard capacity at forty exchanges. There are 6,132 applicants awaiting telephone connections. During the year considerable progress has been made with automatic-tele-phone installations, new exchanges having been opened at Oamaru and Kelburn, while the installations at Palmerston North and Khandallah are almost complete. The installation of automatic exchanges is proceeding at several places in the Auckland metropolitan area, and also at Christchurch. At Wellington and Dunedin the installation of the main exchanges is in abeyance owing to the non-completion of the necessary buildings. With the completion of automatictelephone exchanges at the larger centres the system will be extended to the country exchanges where continuous telephone service is desirable. The necessary apparatus for a machine-printing telegraph system was received in New Zealand in October last, and an installation between Wellington and Christchurch was opened for traffic on the sth December, 1921. The system is now being installed for operation between Wellington and Auckland. This will have the effect of releasing telegraph-wires and making them available for a continuous telephone service between the two centres.

CONTINGENT DEFENCE. The Burnham Industrial School was transferred from the Education Department to the Defence Department and converted into ordnance and mobilization stores for the Southern Command. This change necessitated the erection of suitable buildings for the storage of military equipment. Several wooden hutments have therefore been transferred and are being used as a temporary convenience until a fireproof building is available. For the storage of vehicles buildings are now in course of construction at Trentham. It is proposed later to erect a magazine to store reserves of ammunition for both the Navy and the Military Forces, also to build at Ngaruawahia, on the area of land recently acquired, an ordnance store to take the military equipment for the Northern Command. Featherston Camp will then be dismantled and the hutments sold. LANDS, MISCELLANEOUS. Hauraki Pastoral Areas, &c. —This work consists of the formation, widening, and re-conditioning of roads in the Hauraki pastoral areas, the principal items in hand being the Tapu-Coroglen and Kauaeranga-Tairua Roads, and the Port Charles - Jackson track. Access to a large area of reasonably good country will be afforded by the Tapu-Coroglen Road, and as a result early settlement of discharged soldiers is anticipated along the Tairua Road. Reclamation of Sand-dunes. —Considerable work has been accomplished during the year, and the results achieved are very encouraging. The importance and value of the work is generally recognized, and can be regarded as a truly reproductive work. Where valuable lands are threatened by the drift the work becomes one of necessity, and the ends to be attained are twofold—firstly, the reclamation of the sand-dune area, and, secondly, the protection from injury and possible destruction of valuable adjoining lands now in a productive state. Work has been carried on during the year south of Kaipara Heads in the vicinity of Woodhill, on the east coast between Marsden Point and the Waipu River, and on the west coast near Te Kopuru, in the Northern Wairoa district. A little preliminary work has been done on the west coast north of Kaitaia, near Waiharara. Lands cor Settlement Account. The opening-up of the various blocks of land set apart for selection under the provisions of section 63 of the Land Laws Amendment Act, 1913, was pushed on vigorously during the year. The principal works consisted of road-bridges, drains, and other works necessary to give access to land already selected. DEVELOPMENT OF MINING. The vote of last year under this head was slightly overexpended on the purchase of drill equipment, and even now with the extra supply it is anticipated that during the current year all the Department's drills will be in use, owing to the ever-increasing popularity of this form of assistance to the mining industry. IRRIGATION AND WATER-SUPPLY. Ida Valley Scheme. German Hill Race has been enlarged for a distance of 7j miles. Flumes at Moa, Maori, and Dovedale Creeks are under construction, and four road-deviations have been constructed to avoid several culverts. During the season water was supplied to eighteen irrigators. Manuherikia Scheme. During the year the concrete lining of the intake tunnel, the inlet and intake gates, a concrete gravel-trap, as well as the outlet end of the tunnel, have been completed.

D.—l

The concrete lining of the main race in the Manuherikia Gorge was completed, all excavation finished, and four large flumes erected. A double line of pipes at Chatto Creek has been phased in position, and is in working-order. Ten distributing-races have been completed. Ardgour Settlement Scheme. The permanent line and all siphons have been surveyed and plans prepared. Construction is proceeding satisfactorily, the first 6 miles being fully excavated. From 6 to 11 miles the excavation is practically complete, except for a few short gaps. Earnscleugh Scheme. With the exception of a few culverts this scheme has been completed sufficiently to supply occupied land, but will require extension when other lands are brought into occupation. General Surveys. Upper Manuherikia Scheme. —A detailed survey of the wall for the upper dam site at Lauder has been made, and 60 miles of race have been levelled and pegged. Rough surveys have been made of the Falls and the Dunstan Creek dam sites, and trial race-lines have been run with a view to. irrigating the northerly end of Ida Valley, as well as the Manuherikia Valley, in all about 100,000 acres. Tarras, Roaring Meg, and Bendigo schemes are being investigated. General This may be an appropriate place to give a few particulars of the effects of irrigation on the land as obtained from actual figures supplied by the farmers on Government irrigated land, and some on land irrigated by private schemes. One man grew 400 tons of lucerne on 80 acres of irrigated gvound, and with 350 tons of this fodder he wintered 5,000 sheep, 75 cattle, and 20 horses. With the aid of the pasture on irrigated land he was able to sell 4,900 fat sheep from a property which had never previously been aide to turn out a single fat sheep. Another settler brought in a private scheme costing £20 per acre, and was then able, on 100 acres of land which previously was drifting sand of no value, to winter 3,300 sheep as well as horses and cattle; and in addition, in the month of February, he held 2,000 sheep and fattened 300 wethers. Figures of this description must carry conviction to the most sceptical. Another man, before irrigation, on a little over 300 acres, grazed 100 sheep and fattened 80. He now grazes 600 sheep and fattens 400, and estimates that his land has increased in value five-fold. Another, before irrigation, sold 250 fat sheep and 13 bales of wool per annum. He now sells 1,200 fat sheep and 35 bales of wool; and, further, he estimates that the wool off irrigated land is 2 lbs. or 3 lbs. per sheep heavier and fetches 3d. to 4d. per lb. more as compared with adjoining unirrigated land. Another man who previously sold no fat sheep and four bales of wool, now sells 980 fat sheep and fifteen bales of wool. The increase in the carrying capacity of the land actually irrigated is estimated as increasing from between one-sixteenth and one-quarter of a sheep per acre up to figures ranging between 2 and 10 sheep to the acre. As a means of arriving at the increased production investigations were made as to the number of sheep and other produce sent away from the stations which serve the principal irrigated areas, and it is found that the average weight of goods between 1908 and 191.4 was 1,885 tons, and since that period 4,395 tons; the average of the last year was 5,170 tons. The sheep exported in the six years prior to 1914 averaged 40,345, since that date 52,500, and last year 60,034. Only about 11 per cent, of the fand which might be irrigated is now irrigated, and yet the increase as shown by last year's output as compared with the pre-irrigation average shows: cattle, 35 per cent., sheep, 49 per cent., grain, chaff, and wool, 108 per cent.

The average enhancement in land-values per acre estimated by a number of owners is £6 7s. 6d., after making due allowance for the cost of the water-supply. This amount is much less than the enhancement estimated by Government officers, but naturally the owners would be cautious in estimating the values, particularly as there was no question at the time of their selling. Taking, however, the farmers' values of enhancement, and capitalizing the water-rents receivable, we find that in the case of the Ida Valley scheme we have an asset worth £226,325 from an expenditure of £160,000. If extremely conservative values adduced by the Department's officers from actual crop and flock returns be taken, the national asset is really £281,146 from the expenditure of £160,000. If all the schemes now under construction, or already constructed, be pooled, and the same basis of argument be used on the farmers' estimate we will have a Dominion asset of £498,310 from an expenditure of £370,000, or, on the Department's figures, £619,846 from the same expenditure. All the above values are adduced from sheep-farming operations almost entirely, but, the real future of a considerable amount of the irrigated land lies in the development of dairying, and when the change is brought about —and it can be only brought about by irrigation and subdivision —then the results will be such as could only be believed by persons who have actually seen the country both before and after irrigation. Attached is a diagram showing the relation between the sale of water and the increase in the numbers of sheep carried by a group of irrigated farms in Ida Valley.

WAIHOU AND OHINEMURI RIVERS IMPROVEMENT ACCOUNT. Upper Waihou (Mangaiti-Tirohia Section). —Both banks have been cleared of willows to Tirohia Bridge, a total length of 4f miles. The formation of the preliminary left-bank stop-bank is in hand from 3 miles 42 chains to 5 miles. Tirohia-Ngararahi. —The stop-bank on left side has been completed, partly to preliminary and partly to final levels, over its whole length of 4f miles. On the right bank final level has been reached (with the exception of one small gap at Mill Road) for a distance of approximately 2 miles. The suction dredge pumped 127,000 cubic yards of sand into this bank since the 12th August last.

Ngahina - Waimarie Bend. —Except for temporary drainage gaps, preliminary levels have been reached with the stop-banks on either side of the river. Cut-off drains on the right bank have been completed, and those on the left bank are in hand. Waimarie Bend-Wharepoa. —About If miles of stop-bank on each side of the river has reached preliminary levels. Flood-gates have been erected, and a mile of willows ring-barked. Ngahina Bridge Extension. —The stop-bank on the left bank of this river was commenced last May. HYDRO-ELECTRIC POWER. Of the hydro-electric programme of the Government two schemes are now in operation—Lake Coleridge (12,000 h.p.) and Horahora (8,400 h.p.). These have both shown satisfactory results for the year, both having paid operating-expenses, interest, and depreciation, and shown a margin towards reduction of the accumulated deficiency. Lake Coleridge Supply. The financial result of the year's operation is as follows : — Capital outlay .. .. .. .. .. 671,608 Working-expenses .. .. .. .. 25,911 Interest . . .. . . .. .. .. 20,981 Depreciation . . .. .. .. . . 8,424 Total annual cost . . .. . . £55,316 The revenue for the year amounted to £56,814, showing a net profit of £1,498. This amount was paid off the accumulated deficiency for the previous years of operation, which now stands at a net debit of £29,175. Although the scheme is thus showing a profit on the accounts, no sinking fund is yet provided. In accordance with the State Supply of Electricity Act, 1917, under which these accounts are kept, a sinking fund of 1 per cent, must be set up as soon as there are available profits out of which to pay it. Had this sinking fund been paid last year it would have converted the profit of £1,498 into a loss of £4,458, and had it been paid from the inception of the undertaking it would have increased the accumulated deficiency on the net revenue account by £29,855. Thus, although the results are satisfactory, they are not such as to justify any reconsideration of the standard scale of charges until the sinking fund is provided for. But the savings effected by consumers are very much greater than the revenue received by the Department. To supply the same output as was supplied from Addington substation (33,947,100 units) by means of a modern highly efficient steam station would have taken 45,500 tons of coal —nearly 150 tons per day. But the actual fuel saved as compared with the consumption of the hundreds of small engines used throughout the district before the advent of electric power is three to five times this amount. The operation of the plant was carried out satisfactorily during the year. Trouble with two of the turbine-cases caused some difficulty, and rendered it necessary to fall back on the steam reserve maintained by the Christchurch Tramway Board for a few weeks, but with the hearty co-operation of the consumers all the essential services were maintained in spite of the shortage of power. Insulator troubles are still frequent, but show an improvement as compared with the previous year, as the original insulators purchased in 1912 are replaced by a more modern type, and considerable credit is due to the staff for maintaining the service under the circumstances with such immunity from breakdown. The replacement of the insulators and of the aluminium wire by copper wire will be completed during the current year, and should ensure much greater freedom from interruptions.

The main work during the year was the extension of the plant capacity from 8,000 h.p. to 12,000 h.p. by the addition of a new 4,000 h.p. unit with necessary switch-gear and pipe-line. This was completed and put into service at the end of the financial year, and its influence on the financial returns will not be realized until next year. A further 4,000 h.p. unit is in hand, which will bring the plant up to the full capacity of the existing tunnel and power-house building. This will enable the output to be increased to 16,000 h.p., and will render available a limited supply of 1,000 h.p. reserved for Ashburton, Timaru, and South Canterbury. The transmission-line for this purpose is well in hand. Supply was given during the year to Banks Peninsula and Springs-EUesmere Electric-power Boards. In order to obtain the necessary additional supply of water for these and future extensions the Harper River is being diverted into the lake, and the permanent works for this purpose have now been completed. In order to provide for further extensions up to the full requirements of the district—viz., 36,000 h.p.—the survey has been carried out for a second tunnel, 11 ft. in diameter, and plans are in hand for the extension of the power-house by the addition of two 10,000 h.p. units, with further provision for a third unit of the same capacity when required. Waikato Electric-power Supply. The Horahora power plant has now completed its second year of service since it was taken over from the Waihi Gold-mining Company, and the financial results are as follows :—■ £ Capital outlay . . . . . . .. .. 353,807 Working-expenses .. . . . . . . 7,986 Interest .. .. .. .. .. ..13,187 Depreciation .. .. .. .. .. 4,512 Total costs -.. .. .. .. £25,685 The revenue for the year was £28,207, showing a net profit of £2,522, as compared with a loss for the previous year of £6,282. This result is largely due to the increased revenue received from the mines and dairy factories. In addition supply has been given to Hamilton Borough and to four Electric-power Boards —viz., Thames Valley, Cambridge, Central, and Te Awamutu. For this purpose the transmissionlines have been extended by sixty-seven miles. The maximum load at power-house during the year was 5,800 kw. out of the plant capacity of 6,300 lew., but this has since been reduced owing to a temporary reduction in the mining load. But, again, as in the case of Lake Coleridge, no sinking fund has been provided, and this, had it been paid, would have converted this profit into a loss of £59. The operation of the power-house and transmission-lines during the year has been carried on satisfactorily. In order to provide for the normal, increase in the demand, contracts have been placed for two additional generating-units of 2,000 kw. each, which will bring the full power-house capacity up to 10,300 kw., or 14,000 h.p., which it is anticipated will be fully loaded up before the Arapuni works are completed. The headworks and power-house extensions to accommodate these additional units are now in hand. Mangahao Electric-power Supply. In addition to the two plants in actual operation, work is in hand at Mangahao, Arapuni, and Waikaremoana. At Mangahao substantial progress has been made with the excavation and lining of the two main tunnels, the by-pass tunnel for the Mangahao dam, the excavation for the Mangahao and Arapeti dams, the foundations for the powerhouse, and with the transmission-lines to Wellington. For the supply of the necessary materials thirty-five contracts, amounting in all to £277,000, have been placed.

D.—l

XXIV

The installations when completed will have a capacity of 24,000 h.p., which is the full capacity of the available supply of water. The distribution of the power will be entrusted to Wellington City and seven Electric-power Boards which have been constituted for the purpose. Each of these Power Boards is making good progress. The power will, of course, be supplied to the districts which are first ready to take supply, and, obviously, power cannot be held idle for any district unless it is paid for. But on the basis of all being ready to take up their quota on the completion of the headworks and distribution-lines the following allocation has been made : — Horse-power. Wellington City and district .. .. .. 12,000 Hutt Valley Electric-power Board .. .. .. 2,000 Uorowhenua Electric-power Board .. .. . . 1,200 Manawatu Electric-power Board .. . . .. 3,300 Rangitikei Electric-power Board .. .. .. 1,800 Wairarapa Electric-power Board . . .. . . 2,000 Tararua Electric-power Board . . . . .. 1,000 Dannevirke Electric-power Board . . .. .. 1,300 Negotiations are now in hand for the contract for the supply to Wellington City, but the Power Boards have not yet entered, into negotiations for their supply contracts. The above allocations amount to about one in ten of the population — approximately the same proportion as the output of the Lake Coleridge and Waipori plants bears to the population of the districts supplied. It is therefore anticipated that Mangahao will be fully loaded to the same extent, as those plants now are within a very few years of the inception of supply, and that it will then become necessary to supplement the supply by joining up with Waikaremoana. Arapuni Electric-power Supply. The Arapuni scheme stands on a different footing to the others that have previously been put in hand in New Zealand in that it cannot be developed to advantage in stages to meet the load as it grows. Owing to the large dam and heavy headworks, this scheme cannot pay until the output reaches about 36,000 h.p., and the only district which could offer a sufficient demand to ensure this load being reached in the early future is Auckland City. But the City Council had recently arranged to consolidate and increase its steam plant to 26,000 h.p., and it was necessary, therefore, to know definitely before putting the Arapuni works in hand whether the city intended to take power from Arapuni when available or to continue to operate its steam plant. A contract was therefore negotiated providing for the supply to the city from the Arapuni works, and this contract has been completed by the Auckland Electric-power Board, which in the meanwhile was formed to take over the whole electric-supply system from the City Council. This contract anticipates that the Board will take a supply of at least 15,000 kw. (20,000 h.p.) in 1928, when it is anticipated that the Arapuni works will be ready to supply, the Board building up its load to this or such greater demand as may be available in the meanwhile by means of its steam plant. In the meanwhile the surveys and preliminary works at Arapuni have been put in hand. Waikaremoana Electric-power Supply. Tins power-station will be required in the early future, mainly to supplement the demand for power from Mangahao Power-station, and the proposal is to then provide an installation of 40,000 h.p. In the meanwhile the exciter units of the large plant consisting of two 500 h.p. water-wheels coupled to 350 kw. alternators and direct-current generators are being installed in a temporary power-house, and will be utilized at once for supply to the Wairoa Electric-power Board up to a capacity of 750 h.p., the balance of 250 h.p. being reserved for the construction of the main works.

D—l

XXV

In order to reduce the overhead expenses an arrangement has been entered into to lease the plant to the Power Board, who will operate and manage it by means of its own staff, thus keeping the operating-cost at a minimum. In addition to the installation of this 1,000 h.p. plant which has been completed, surveys for the main scheme have been pushed on, including a survey for a sawmill tram-line and investigation of the foundations of the main power-house. The necessary permanent-road improvement and new-construction roads and bridges have also been carried on during the year, accounting for the greater portion of the capital outlay hitherto incurred. Whilst these will not be required for the construction of the new works for some time, they will be immediately useful in serving to improve the access for the settlers of the district. Electric-power Boards. Whilst the responsibility of generating and transmitting the electric power in bulk rests on the Government, it is intended that the whole of the reticulation shall be undertaken by the Electric-power Boards, and the Power Boards Act and its amendments gives these Boards full powers and responsibilities in this direction. The legislation is so far optional on the part of the ratepayers of any district —that is to say, a Power Board can only be formed on receipt of a petition from the ratepayers. Hitherto twenty-three such Boards have been constituted, covering about one-third of the Dominion. Petitions are in course of preparation for ten more districts, which will increase the proportion of the Dominion included in electricpower districts to one-half. In order to ensure the most efficient subdivision of the whole Dominion a suggested scheme of forty-one electric-power districts was drawn up in the last annual Statement. Of the twenty-three Boards now constituted, nineteen of them correspond closely to the scheme there laid down. The other four are for small areas, and were constituted to deal with an urgent demand in a special district ; and as the demand extends and the power becomes available to meet the demand over a comprehensive area, these districts must be extended or merged with adjacent districts in order to ensure the most efficient results. In order to meet this position special legislation is being introduced this year providing for the merger of adjacent electric-power districts. Several petitions are in course of preparation for the formation of further large districts in accordance with the general scheme laid down, but it is a serious question as to whether the procedure should not be mandatory instead of permissive—that is to say, whether the whole country should not be incorporated in electric-power districts, either in rateable inner areas or, if there is no immediate prospect of supply being given in that district, in non-rateable outer areas. This would enable the question of electric supply, which is now a necessity to the industrial development of the Dominion, to be considered in a comprehensive manner for the whole Dominion. Of the twenty-three districts already constituted four are now taking power from the Government power-station at Horahora, four have entered into contracts to take supply from other Government schemes, eight propose also to do so, and seven of the districts are outside the area within which a supply of power is available from the Government stations. Three of these —Southland, Opunake, and Teviot —have arranged to install their own power-stations, and the other four have not yet decided upon their source of supply. Whilst the main object of the Electricpower Boards is to undertake the distribution of the power supplied in bulk by the Government, the Boards must, of course, set up their own generating-station or make other arrangements to obtain power in districts in which a Government supply is not yet available. The suggestion has been made that some of the Boards are not spending their funds to the best advantage, and thus increasing the cost of power to the consumers. In two or three cases the Boards in their desire to give a general supply over the whole of their inner area have constructed or arranged to construct lines which will not be remunerative for some years. The responsibility of licensees to supply in their district has not been clearly defined in the past. New regulations are

iv—D. 1.

D.—l

XXVI

being issued which render this responsibility quite definite but at the same time protect the interests of the licensee or Board by giving them the power to require from prospective consumers a guarantee for a period of five years of an annual revenue from any line at a rate not less than 20 per cent, of the capital cost of such line. The Power Board would, of course, lay out its original reticulation of the districts, which will obviously be remunerative, and would then extend it piece by piece under this guarantee to the more remote and sparsely settled portion of its area, thus ensuring an ultimate supply to all who require it, and at the same time ensuring a sufficient revenue to the Board to render the scheme self-supporting as it develops. As long as the Boards generally administer their affairs economically it is desired to leave the question of their internal policy in their own hands as representatives of the ratepayers concerned. But if it is found that work is being done that will involve undue cost of power to consumers, thus restricting the development of the output of the main Government station, it may be necessary to take power by legislation to enable the Department to review the Board's estimates at the beginning of each financial year. If, on the other hand, it is found that a Power Board fails to adopt a sufficiently progressive policy to ensure the disposal of the proportion of the output of the Government power-stations developed for that particular district, it may also become necessary for the Government to protect itself in this direction in making the contract for the supply of power to the Board. On the whole the Electric-power Board legislation has so far proved successful in putting into the hands of the ratepayers themselves the responsibility of undertaking the distribution of the power and in giving them a local interest in ensuring the financial success of the undertaking. Local Electric-supply Systems. In addition to the Government and Power Boards systems, the Department is responsible under the Public Works Amendment Act, 1911, for the licensing and supervision of all the electric-supply systems of the Dominion. The industry as a whole now involves a capital outlay of £5,224,629, and after paying workingexpenses and capital charges at an average rate of 5-85 per cent, it yielded a net profit of £82,688, or 1-6 per cent, additional on the capital outlay. Full details are included in the tables herewith. Future Developments. IWith regard to future developments, a programme was set out in my last annual Statement covering a total expenditure of £12,902,000 spread over a period of ten years, providing 260,000 h.p. and reaching a maximum rate of expenditure of £2,023,000 in 1925. The financial position has rendered it necessary to revise this programme in order to keep the annual expenditure per year, in the meanwhile, down to about £1,000,000. To do this it has been necessary to postpone for a couple of years the commencement of the main works at Lake Waikaremoana, and to hold over a number of the smaller developments in the South Island until the Power Boards are constituted to deal with the reticulation. At the same time the transmission-lines from the schemes to be proceeded with will be pushed on, in order to make the supply as general as possible within the capacity of the headworks at each site. With this object the mains from Lake Coleridge will be extended into Otago and North Canterbury, and from Mangahao to Wanganui and Napier, in addition to the lines already under construction. The revised programme herewith provides for a slightly less total expenditure (£11,355,000) spread over a longer period, and keeps for the first few years within the limit of £1,000,000 per annum.

Electric-power Organizations. The work involved in the development of the electric-power resources of the Dominion is outgrowing the present organization as a hranch of the Public Works Department, and a Special Board or Commissioner will be necessary in the early future to deal with the commercial, financial, and electrical and engineering problems involved. Owing to the financial stringency the appointment of this special Board has been postponed as long as possible, but will be necessary in the early future, and a careful note is being kept of the development of the corresponding organizations in Great Britain, Canada, and Victoria, where the work is undertaken by Electricity Commissioners ; in Tasmania, where a separate Hydro-electric Department has been set up ; and in New South Wales, where the organization is carried out by a branch of the Public Works Department; and the local proposals will be based on those which are proving most efficient elsewhere. STAFF. The work of the whole of the Staff during the past year' is worthy of the very highest commendation, and I desire to take this opportunity of expressing to all those officers my thanks for their untiring energy and hearty co-operation in carrying out successfully the many and varied functions of the Department. It is with sincere regret that I have to record the loss by accident of a promising young Assistant Engineer, Mr. 8,. W. Miller, who unfortunately lost his life through being gassed while endeavouring to rescue some of his men similarly affected in one of the tunnels being constructed in connection with the Mangahao hydro-electric scheme. CONCLUSION. In conclusion, I feel confident that the judgment of the country will be that substantial results have been achieved. The money at my disposal has been expended in accordance with my ideas of what is in the best interests of New Zealand as a whole. Under the direction of a thoroughly qualified staff, and with a due regard to the necessity of obtaining, in increased production due to better communications, an adequate return for the expenditure.

Kaihu Valley Railway Extension. (19 m. 17 eh. to 23 m. 71 eh. ; length, 4- miles 54 chains.) All the formation work on this line has been completed ; all culverts are also completed, and the fencing is practically finished. Platelaying was completed both on main lines and in station-yards during the year. Ballasting is practically completed ; only a small amount has yet to be spread at the Aranga and Donnelly's Crossing station-yards. A good deal of delay occurred in procuring materials for the bridges on the line. One bridge at Donnelly's Crossing Station is completed. The piers of the other two bridges at 21m. 24 eh. and 22 m. 65 eh. are completed, and the steel girders are now being placed in position. Platforms and loading-banks at the stations are finished, but no buildings have yet been erected. All timber for these buildings has been cut at the Department's new mill at Whatoro, and has been delivered on to the sites. It is intended to immediately call tenders for the erection of the buildings. The carriage of goods, which service was started in September, 1920, to Aranga Station, was extended to Donnelly's Crossing in October, 1921. During last summer large quantities of logs and other materials were hauled over the line. This line should be completed, with the exception of the station buildings, by the end of September. North Auckland Main Trunk Railway. Ngapuhi Northwards. Okaihau Section (16 m. 25 eh. to 24 m. 45 eh. ; length, 8 miles 20 chains). —Formation on this length was finished last year, but large slips in the cutting at 19 m. 68 eh. and in Okaihau station-yard have still to be removed. A steam-shovel is now engaged in removing the one in Okaihau yard, after which it will shift the slip at 19 m. 68 eh. The high bank at 19 m. 55 eh. gave further trouble, and 8,400 cubic yards of stone were placed in the bank to drain it. This has been very satisfactory, and the bank now appears to be stable. A small bank at 20 m. 17 eh. has also given trouble. The culvert under the bank was broken by a slip on the bank and had to be removed, and a new culvert has been put in. On account of the unstable nature of the material in the bank, which was derived from an adjacent cutting, most of it will have to be removed and a new bank made from scoria rock. No further platelaying has been done during the year. The rails extend to the beginning of Okaihau station-yard, and the yard is now being laid. The large stone-crushing plant for ballast and road-metal is now in good working-order, and is turning out stone at a very satisfactory cost. Prom this quarry the line has received the first lift of ballast from 16 m. 25 eh. to 24 m. 14 eh., and the Okaihau yard is now being ballasted as the main line and sidings are laid. At Okaihau stationyard a concrete block platelayer's cottage is being erected, and a water-supply is being installed. Material is also on the site for the erection of a cattle-yard. Goods traffic has been run on this line since the beginning of March last. During the greater portion of the year very few men were employed on this section, but additional men were put on at the end of March, and better progress is now being made. North Auckland Main Trunk Railway. Paparewa Section (90 m. 30 eh. to 92 m. 13 eh. ; length, 1 mile 63 chains).—During the year the second and third lifts of ballast were put on throughout the main line on the section. No platelaying or ballasting has yet been done in Paparoa station-yard, owing to the uncertainty as to which station would be adopted as the subtcrminal on this railway. The erection of the fencing and construction of the culverts were completed throughout the year. A good deal of cleaning-up work yet remains to be done, although much was done during the year. Mareretu Section (92 m. 13 eh. to 96 m. 20 eh. ; length, 4 miles 7 chains). —About 3J miles of fencing was done on this section during the year. Five concrete and five earthenware-pipe culverts, and a large number of pipe-culvert ends, were constructed. The formation is practically completed as far as Golden Stairs Tunnel, but slips occurred in most of the cuttings. These have been cleared sufficiently to allow traffic to get through. A bank at 93 m. 14 eh. has subsided badly, and a temporary line has been made round it. In order to transport plant and materials to the northern side of Golden Stairs Tunnel for the earthwork and tunnel at that end, a service tramway, 1J miles long, has been laid to the top of the tunnel. A cable incline is used to lower the wagons on the other side of the tunnel. The formation beyond the tunnel has been done to 94 m. 71 eh., and is well in hand from here to the end of the section. Two steam-shovels have been employed on this length. A good, many of the cuttings turned out to be very heavy pug, which could only be excavated economically by steam-shovels. The formation of the station-yard at Mareretu is on particularly bad ground, and had to be abandoned until steam-shovels became available. A considerable number of plough a.nd scoop teams have been employed, but, owing to wet weather and the heavy nature of the earth, have not worked so economically as the steam-shovels. The Golden Stairs Tunnel, which is the chief work on this line, is progressing very satisfactorily. There is now 18| chains of tunnel completely excavated and lined with concrete, of which. 12| chains is done at the south end and 6 chains at the north end. Both ends of the tunnel are now fully manned, and the tunnel should be completed before the end of the year. At both ends the country has been in good and hard sandstone, and only light timbering has been necessary. This justified the extensive deviation made in 1920. The permanent telephone-line has been erected throughout this section. About half a mile of platelaying was done, bringing the permanent-w T ay up to the Golden Stairs Tunnel. Ballasting on the second and third lifts was done from Paparoa Station to Golden Stairs Tunnel. No ballasting has yet been done beyond the tunnel.

Waikiekie Section (96 m. 20 eh. to 107 m. 25 eh. ; actual length, 10 miles). —Formation-work between 96 m. 20 oh. and 100 m. 40 eh. is well in hand, and from 100 m. 40 eh. to the end of the section is practically complete, except for the removal of a large number of slips. The difficulty of railway-building in this country may be understood from the fact that there is only one cutting in the whole section that has not slipped. There is nothing better than the steam-shovels for removing the slips, and three of the seven shovels working on this section are engaged on slip-removal. The largest work on this section now is the cutting at 96 m. 37 eh., where a steam-shovel is engaged, and on which another is to be placed in order to complete the cutting by January next. The whole of the other formation work should be finished simultaneously with this cutting. Between 102 m. 48 eh. and 103 m. 9 eh. a deviation of the line had to be made, as practically the whole country was slipping, largo cuttings after excavation having been completely filled in again. The formation of the Taipuha station-yard is in hand, but is being delayed by severe slips. The formation of the Waikiekie and Waiotira station-yards is practically completed, the latter station requiring a filling of over 30,000 cublic yards to make it up. The filling and the approaches to an overbridge across the station have been done by two steam-shovels. The employment of a large number of steam-shovels has been of inestimable value in the heavy formation work along this section, and very poor progress would have been made without them. Fencing is well on towards completion on the section, The Mareretu Tunnel was completed last Easter. Owing to slides and heavy ground the piercing of this tunnel was an exceedingly difficult operation. Very heavy timbering, closely placed, had to be used right through, and concrete lining varying from 18 in. to 2 ft. thick had to be used with an invert section. It was only by vigorous pushing-on of the work and close following-up with the concrete lining that the country could be held. All the material for the south end of the tunnel had to be hauled up by a cable tramway over the top of the tunnel. At the tunnel, huts, cookhouse, bath houses, septic tanks, and a large recfeation-hall were built. The understructure of the Managawai River Bridge is practically completed. Considerable difficulty was experienced in obtaining a foundation on account of the soft ground, which necessitated cradling and lengthening the piles by splicing. The Kikowhiti Stream Bridge is now well under way, all the staging and preliminary work having been completed. An overbridge at the north end of Waiotira station-yard has been finished, and work is in hand on the erection of the overbridge at the south end of the yard. Ironbark and other hardwood timbers have been received to do all the remaining bridges on the section. Platelaying has been completed from Waiotira Junction station-yard (107 m. 9 eh.) southwards to 102 m. 12 eh. The temporary line south of 102 m. 12 eh. is now being lifted and replaced with the permanent rails. The sidings are now being laid in Waiotira and Waikiekie station-yards. The first lift of ballast has been placed from Waiotira station-yard to 102 m. 12 eh., and the second lift to 106 m. 12 eh. From 102 m. 12 eh. to 100 m. a small lift of ballast was placed under the temporary track laid between these points. A few culverts wore completed, but most of them were left until the rails were laid and materials therefore more cheaply obtained. Work is now proceeding on these culverts that were left. During the year sixty-eight single huts and eighteen married men's quarters were erected for the workmen. The construction of cable tramways over the tunnels on this section has greatly facilitated the handling of materials, and expedited the formation work and ballasting. A considerable saving was also made in cartage costs by these and other temporary tramways at grade level. A number of small construction locomotives were purchased and used to haul materials over these temporary tracks, as well as to handle earth excavated by the steam-shovels. Passenger and goods traffic has been run between Waikiekie and Waiotira Stations for the last few months. Kirikopuni Section (107 m. 25 eh. to 121 m. 40 eh. ; length, 14 miles 15 chains). —A temporary tram-line was completed from the Wairoa River to the Omana Tunnel. A lift of ballast was put on this track to enable heavy traffic to be carried safely. A limestone quarry was opened up and a crushing plant installed in order to obtain this ballast. A small construction locomotive is used to run ballast and other material and attend a steam-shovel. The northern approach cutting to the tunnel, which consisted of a heavy sticky pug, was taken out by a steam-shovel. This shovel is now engaged in taking out the cuttings between the Wairoa River and the tunnel. A start was made on the tunnel, but owing to the treacherous nature of the ground it was impossible to commence driving in the usual way, and it was therefore decided to build three lengths of special reinforced-concrete section of lining. One of these lengths has been constructed. A large quantity of timber and slabs have been delivered for the tunnel excavation. Forty-six single huts and eight married men's quarters, together with a cookhouse and bath houses, have been erected for the men in the tunnel and vicinity. An adequate water-supply has also been installed, as well as a septic tank and other sanitary appliances. All timber was procured from the Department's sawmill at Whatoro. It is proposed to divert this line to cross the Wairoa River at Omana instead of at Kirikopuni, and a start is about to be made on the survey of this deviation. Whangarei Branch Railway. Oakleigh Section (5 m. 27 eh. to 7 m. 60 eh. ; length, 2 miles 33 chains). —A deviation was made at 7m. 15 eh. to avoid a very bad slip in a cutting at this point. The banks at 7m. 7 eh. and at 7 m. 23 eh. have both slipped badly, and necessitate constant repairs to keep the line open for traffic. A steam-shovel was engaged for seven months removing a slip at 6m. 18 eh. The steam-shovel is now on other work, but later on will be needed again to remove slips in this cutting. The fencing of the railway reserve has been finished. The rails have been laid throughout the section, and ballasting is practically completed. Goods traffic is now being handled over this section.

D.-l

Tauraroa Section (7 m. 60 eh. to 14 m. 67 eh. ; length, 7 miles 7 chains). —Work on this section has been confined chiefly to the removal of slips and the usual maintenance of the track. A high bank at 9 in. 75 eh., near Mangapai, has given a lot of trouble through subsidence, and several drives are now being put in to thoroughly drain the foundations. The large stone-crushing plant at Tauraroa has been running continuously, and has crushed 22,000 cubic yards. The capacity of the plant has been increased so as to provide for the large amount of ballast required on the North Auckland Main Trunk Railway. Tenders have been invited for the quarrying and crushing of the ballast. Waiotira Section (14 m. 67 eh. to 19 m. 79 eh. and junction with North Auckland Main Trunk Railway at 107 m. 22 eh. ; length, 5 miles 12 chains). —A. great many slips have been removed by steam-shovels during the year. Two deviations of the line were made to avoid as far as possible particularly bad places, and have saved a good deal of work. A drainage drive was put in the bank at 17 m. 10 eh. ; and has prevented further sliding of the bank. Large stone drains arc being put in, and pipes laid in nearly all the cuttings throughout this section to drain the formation. A few further slips at 16 m. 30 eh. will have to be dealt with later when a steam-shovel is available. The lino from 18 m. 27 eh. to 18 m. 60 eh. has been raised so that it will bo above the level of the exceptional flood which occurred after the line was first formed. All the culverts on this railway are now finished. The breaks in the permanent-way were laid, thus completing the rail-laying on the branch railway. The third lift of ballast was placed between 18 m. 40 eh. and 19 m. 67 eh., and. only a short length of the whole section requires a final lift. A mechanical tamping plant, driven by compressed air, was used, and has given most satisfactory results. The fencing has been completed. Goods traffic has been run over the whole line throughout the year, and has been fairly heavy between Oakleigh and Waiotira. A wharf gang is continuously employed at the former place discharging and loading from steamers and scows. Waipu Branch Railway. Ruakaka Section (0 m. to 9 m. 20 eh. ; length, 9 miles 20 chains). —The only work that has been carried out on this railway during the year has been, the banks across the mud-flats between 0 m. 15 eh. and om. 76 eh. These banks, which arc now completed, were made with material excavated from a borrow-pit by a steam-shovel. The material was good, and has been taken out at a very economical rate by the shovel. Waiuku Branch Railway. Glenbrook Section (5 m. to Bm. ; length, 3 miles). —The third lift of ballasting was put on along this section during the year, and all other work completed. Waiuku Section (8 m. to 12 m. 15 eh. ; length, 4 miles 15 chains). —The second lift of ballast was placed between 10 m. and 12 m. 15 eh. The final lift and the ballasting of the station-yards was done. Overbridges and the station buildings were all completed during the year. This railway was handed over to the Railway Department on the 10th May last. Huntly-Awaroa Railway. (7 m. 20 eh. to 10 m. ; length, 2 miles 60 chains.) Heavy formation work has been in progress during the year on this railway. Three steamshovels are engaged on this work, and, considering the difficult nature of the material to be excavated, have done good work. The big bank at 7m. 25 eh. is practically completed, as well as the cutting at 7m. 40 eh. from which the bank material is obtained. Formation has been completed from 7m. 42 eh. to Bm. 6 eh. An amount of 33,000 cubic yards has been taken out by one steamshovel. The very large summit cutting, consisting of sticky pug overlying hard rock, is being excavated by a steam-shovel at each end. This cutting, the material from which is being used to make up the Glenafton Station, is the largest work on the railway, and is nearly half-completed. The selected position and character of the material to be shifted makes this a very T difficult cutting. A road deviation from Bm. 35 eh. to Bm. 7 eh. was done, and an overbridge at Bm. 45 eh. is in hand. A large concrete drain to carry water from a swamp and creek above the station-yard has been put in from 8 m. 27 eh. to 8 m. 37 eh. East Coast Main Trunk Railway. Wadhi Eastwards — Athenree Section (0 m. to Bm. 68 oh. ; length, 8 miles 68 chains). —The earthwork has boon completed on this section except where material is required for bridge approaches, in which case the cuttings from which earth is available have been left until the bridges are completed. The widening of the Athenree station-yard is now in progress. Road deviations at Bm. 13 eh. and Bm. 62 eh. have been practically completed. Five culverts were put in, and an 8 in. arch culvert at Bm. 5 eh. is in hand. Fencing was done on both sides from 4m. 58 eh. to 6m. 55 eh. The telephoneline was erected from Waihi to Athenree. The stone-crushing plant was removed from Bm. 20 eh., and re-erected at 7m. 25 eh. The concrete piers for the Mangatoetoe Bridge at om. 3 oh. arc completed. Most of the steel girders are on the site. The concrete piers for Adams Street Bridge and for the five bridges over the Waiau Creek are now all in hand. The overbridge at Bm. 13 eh. was completed and open for traffic. The abutments for the subway at Bm. 62 eh. were completed. Arrangements have been made for the steel.superstructures for all bridges on this section. Katikati Section (8 m. 68 eh. to 17 m. ; length, 8 miles 12 chains.). —The formation on this section has been finished from Bm. 71 eh. to 10 m. 29 eh. The formation is well in hand from 10 m. 29 eh. to 12 m., and has been started from 12 m. to 14m. in various places. A culvert was built at 13 m. 17 eh., and two others have been started. Fencing was done on both sides for a distance of 2 miles. The permanent-line survey was completed to the Wairoa River at 35 m. 15 eh.

Tauranga Westwards - Tauranga Section (35 m. to 41m. 5 eh. ; length, 6 miles 5 chains). —The formation is now done from 35 m. 26 eh. to 39 m. 55 eh., with the exception of four gaps totalling about 28 chains in length. Stone-pitching the embankment was done from 35 m. 65 eh. to 36 m. An overbridge at 38 m. 35 eh. was completed, and the bridge approaches and road to overbridge at 40 m. 22 eh. are in hand. The stationmastcr's house and four platelayers' cottages were erected at Tauranga station-yard. Tauranga Eastwards - Malapeehi Section (41 m. 5 eh. to 45 m. 0 eh. ; length, 3 miles 75 chains). —• The approach bank on the east side of the Tauranga Harbour Bridge was completed during the year. Progress on the Tauranga Bridge has not been very rapid, owing to the bad formations encountered, but the cylinder piers are now nearing completion, and a start will be made almost immediately with the erection of the steel girders. During the year 106 ft. of concrete cylinder was made, and 155 ft. sunk into position. Considerable difficulty and delay was experienced in sinking cylinders in pier P owing to tho presence of timber. In six of the piers the cylinders are now sealed and ready to receive the concrete core filling, and in one pier the cylinders are filled. The manufacture of the steel girders for this bridge is being done at the Department's Workshops at the Mount. One span has been completed and erected at the shops, and the majority of the steel for the other spans has been fabricated. Mount Branch (0 m. to 4m. 7 eh.; length, 4 miles 7 chains). —In the Mount station-yard extensive alterations and additions have been made to the sidings to accommodate extra traffic in connection with the workshops, and to provide for general increase of traffic on the line as it is extended. Workshops were enlarged during the year, and are now carrying out a large amount of steel-manufacturing for the Department's works all over the Dominion. In addition to the fabrication of tho Tauranga Bridge, steel girders are being made for bridges on three other railways. Repairs were made to all locomotives and to rolling-stock as required. Sixty new M hopper-wagons were built, as well as a large number of earth-wagons. During the year 146 double huts and 173 single huts for workmen were built. Te Puke Section (45 m. to 54 m. ; length, 9 miles). —The banks have been raised where subsidences have occurred, and the line generally maintained in good order for the running of traffic. At tho To Puke ballast-quarry about 10,000 cubic yards of rock were crushed and delivered on to the construction works, or sold for road-metal to the local bodies. In addition to the crushed metal, 16,000 cubic yards of inferior stone spalls were taken from the quarry, and used for protection work along the railway. Paengaroa Section (54 m. to 59 m. 67 eh. ; length, 5 miles 67 chains). —In addition to the ordinary maintenance of the railway, a 2 ft. arch culvert was put in at 56 m. 25 eh., and a private crossing made at 59 m. 67 eh. Pongakawa Section (59 m. 67 eh. to 64 m. ; length, 4 miles 13 chains). —An overbridge was erected at 61 m. 50 eh. Except for this, work was confined to tho usual maintenance of the railway. Otamarakau Section (64 m. to 71 in. 5 eh. ; length, 7 miles 5 chains). —A considerable amount of work has been done during the year on this section in raising and widening banks. At Otamarakau Bluff 11,000 cubic yards of spoil were excavated by hand-work, and 16,000 cubic yards by steamshovel, and utilized for the making-up of the banks, 12,000 cubic yards being used on this section and 15,000 cubic yards on the Matata Section. The work was considerably hampered by the necessity for keeping traffic open during the running of the spoil on to the line. Another steam-shovel was employed excavating from a borrow-pit for the making-up of the Otamarakau station-bank. The spoil excavated by tho shovel was transported by a caterpillar tractor and bottom-dump wagons. In four months' time 23,000 cubic yards were excavated and transported an average distance of 24 chains, at a cost of less than Is. per cubic yard. A 3 ft. Armco culvert was put in at 64 m. 56 eh. A number of concrete posts were made at Otamarakau, as well as a few concrete piles. Matata Section (71 m. 5 eh. to 79 m. 16 eh. ; length, 8 miles 11 chains). —A quantity of 15,000 cubic yards was obtained from Otamarakau Bluff to raise and widen the banks on this section. An 8 ft. arched concrete culvert is now in hand at 77 m. 40 eh. Reinforced-concrcte bridges are being erected at 75 m. 54 eh. and 76 m. 16 eh. Rangataiki Section (79 m. 16 eh. to 87 m. 71 eh. ; length, 8 miles 55 chains). —Cuttings from 79 m. 55 eh. to 80 m. 5 eh. have been widened; 85 chains of side drains were cut. A steam-shovel has been constantly employed at Awakaponga excavating material for the construction of the banks between 83 m. and 88 m. During the year 78,500 cubic yards were taken out, at a very low cost, considering the distance the material had to be transferred. One concrete culvert was completed and two others are in hand. A rcinforced-concrete bridge was completed at 79 m. 24 eh. One and a half miles of fencing was done, and additional sidings were put in at Awakaponga Station. Awakeri Section (87 m. 71 eh. to 91 m. 40 eh. ; length, 3 miles 49 chains). —Very little work was done on this section except to keep it open for traffic. Two and a quarter miles of fencing was done, and a little widening of the banks. Taneatua Section (91 m. 40 eh. to 100 m. ; length, 8 miles 40 chains). —One and a quarter miles of formation was done, practically completing the earthwork to as far as 96 m. 67 eh. A steamshovel has been employed on portion of this distance. The cutting at 97 m. 10 eh., which is being taken out with another steam-shovel, is now well on towards completion. A third steam-shovel is now being installed at 97 m. 25 eh. for the purpose of excavating the large summit cutting. From here on to 98 m. earthworks are now well in hand. Forty chains of side drains have been cut; ten concrete culverts and two earthenware-pipe culverts were constructed. One mile of fencing was done, and permanent-way was laid for a distance < of 12 chains, making the railhead now at 93 m. 35 eh.

Gisborne-Napier (North End). Ngatapa Section (0 m. to 10 m. 29 eh. ; length, 10 miles 29 chains). —The formation in Repongaire station-yard was widened. Between 9m. 40 eh. and 9m. 65 eh. the formation was raised, and the raising of the Ngatapa station-yard to its new level was completed. The third lift of ballast was completed from 9 m. 40 eh. to Ngatapa station-yard (10 m. 29 eh.), and some ballasting was done in the station-yard. The lino has been maintained and a regular goods and passenger traffic service run. Waikura Section (10 m. 29 eh. onwards).- The formation was raised from 10 m. 40 eh. to 11 m. 23 eh. The cutting at 11 m. 63 eh. has given a good deal of trouble with slips, which wore removed by steam-shovel and utilized to raise Ngatapa station-yard, and banks at other places. Cuttings at 12 m. 34 eh. and 12 m. 50 eh. wore finished during the year. The formation is now practically finished to 13 m., and very little has been done beyond this. The first lift of ballast was completed to 11 m. 50 eh., the second to 10 m. 60 eh., and the third lift to 10 m. 45 eh. Waikokopu Branch Railway. Nuhaka Section (0 m. to 17 m. 12 eh. ; actual length, 18 miles 65 chains). —The large cutting at 0 m. 40 eh. was practically completed by steam-shovel and hand labour during the year, over 60,000 cubic yards being taken from the cutting. The slopes of this cutting are now being flattened, and the material is being used to raise and widen the bank from Im. 50 eh. to 3m. This raising and widening process is necessary where the bank has been built with material from tho peat swamp between Im. 50 eh. and 4m. Fencing is well on towards completion on this section. The understructure of the bridges at 1 m. 2 eh. and 1 m. 23 eh. was completed, and temporary stringers erected. Pile-driving is in hand on tho bridges at 3m. 76 eh. and 13 m. 62 eh. Hardwood for most of the bridges is now on tho sites. The rails have been laid from om. 5 eh. to Im. 20 eh., an actual distance of 3 miles, and a further 50 chains were laid to the wharf on the Wairoa River. Platelaying-materials were also unloaded at Waikokopu Harbour and carted back to Nuhaka, and the permanent-way has been laid from 17 m. 21 eh. back to 13 in. 62 eh. A branch line 50 chains long to a ballast-pit opposite 15 m. has been laid. The stripping of the ballast-pit at 15 m. is now being done. About 20,000 cubic yards of stripping has been removed. It is proposed to erect a drag-lino excavator here to dig out the ballast and load it on to the trains. It is proposed to work another ballast-pit at Wairoa, and the prospecting-work has been done at this pit. At Wairoa station-yard a Stationmaster's house and three platelayers' cottages, and at Nuhaka Station two platelayers' cottages, were completed. Waikokopu Section (17 m. 12 eh. to 23 m. 5 eh. ; length, 5 miles 73 chains). —Formation has been practically completed up to 22 m. There are still two cuttings to bo completed at 21 m. 19 eh. and 21 m. 60 eh., but these should be done in a month or two. Formation is also well in hand from 22 m. to the end of the section, the only large remaining earthworks being a bank of 20,000 yards at 22 m. 30 eh. and two cuttings in the Waikokopu station-yard. Two steam-shovels were employed on the formation of this section. Most of the fencing is completed or in hand. Pile-driving for the Nuhaka River Bridge at 17 m. 50 eh. is well on towards completion. Several concrete culverts were completed, and the construction of a large 12 ft. arched culvert at 22 m. 30 eh. is now well advanced. Hardwood timber for the bridges on this section is now arriving, and contracts have been lot for all the steel girders for the superstructures. The rails have been laid from 17 m. 12 eh. to 17 m. 47 eh. A large number of rails and sleepers have been landed at Waikokopu Harbour, and some of them have been carted back to 19 m. 60 eh. to lay the line between 17 m. 47 eh. and 19 m. 60 eh. Gisborne-Napier (South End). Eskdale Section (0 m. to 10 m. 51 eh. ; length, 10 miles 51 chains). — The formation on this section is done, with the exception of a small gap in the bank at 0 m. 32 eh., over which a temporary bridge has been built. The Harbour Board filled in the gap at om. 55 eh., and their contract, with the exception of this and some dredging of the river-channel, is completed. Both sides of the railway have been fenced to 3m. Rail-laying has been done to 2m. 49 eh., and has received a bottom lift of ballast. The ballast has also been placed on the formation from the railhead to sm. 50 eh. The telephone-line has been completed along the section. Two platelayers' cottages wore erected during the year in concrete blocks at Eskdale Station, and a Stationmaster's house is now in course of erection. Tutira Section (10 m. 51 eh. onwards). —The formation of this section is practically completed to 14 m. 47 eh. A good deal of the excavation was done with a steam-shovel, which is now working in a long cutting at 14 m. 47 eh. Several cuttings have been opened out between this and 16 m. The formation of the service road was completed from 17 m. to 19 m. 40 eh. A concrete culvert at 15 m. 6 eh. was completed ; a water-drive at 15 m. 44 eh. was finished, and one at 15 m. 21 eh. is in hand. Reinforced-concrete piles for bridges at 11 m. 41 eh. and 13 m. 35 eh. have been completed. Stratford - Main Trunk Railway. (East End.) Matiere Section (0 m. to 10 m. 23 eh. ; length, 10 miles 23 chains). —Formation has been trimmed and platelaying has been completed to tho Matiere Township at 9m. 49 eh. A temporary station has been provided here, and two locomotives are constantly employed in ballasting and running a goods and passenger service. A considerable quantity of slips had to be removed, and five temporary bridges were erected, in order to enable the platelaying to proceed. The combined road and railway bridge over the Ongarue River at om. 7 eh. was completed in November last. In this bridge the railway is carried on the upper level, while lower road-traffic deck is carried on the bottom chords of the two

60 ft. trusses. Subways have, been erected at 4m. 20 eh. and 6m. 79 eh. The concrete-work for the Ohura River Bridge at 7 m. 67 eh. has been completed, and work is in hand on the other bridges on which there are at present temporary superstructures. The steelwork for these bridges is being manufactured at the Department's Tauranga workshops. All tunnels have been completed, and the principal work still remaining on this section is the completion of ballasting, finishing of bridges and station-yard at Tuhua, together with the erection of the necessary station buildings at Tuhua and Matiere. Ohura Section (10 m. 23 eh. to 19 m. 70 eh. ; length, 9 miles 47 chains). —This section was closed down during the previous period, but during the current year the work was again put in hand, primarily as a relief work ; but as this was only towards the end of the period there is very little to report. (West End.) Tahora Section (42 m. 26 eh. to 47 m. 40 eh. ; length, 5 miles 14 chains). —Formation-work .and platelaying on this section have been completed, but no ballasting has been carried out during the period, as material which had previously been obtained from Mount Egmont quarry was not available. Culverts, drains, fencing, &c, have been completed, as well, as the stone-pitching at No. 1 and No. 3 bridges. The shelter-shed, latrines, goods-shed, water-vat and stand have been erected at Tahora, and the station-platform and loading-bank, together with goods and wicket entrance to goods-shed and station, are completed. A small reservoir of 4,000-gallons capacity was completed, and 1,800 ft. of pipe laid to connect with the station supply. Raekohua Section (47 m. 40 eh. to 50 m. 60 eh. ; length, 3 miles 20 chains). —Work was closed down on this section, and nothing has been done during the past year. Te Wera Quarry. —The formation of the branch line, 1J miles long, has been completed, together with 8 chains of siding to the bins and 15| chains of incline between the bins and the quarry : I mile 16 chains of rails have been laid, together with sidings and inclines. The branch line has been connected with the main line at 22 m. 63 eh., and all fencing and crossings, except the incline and the quarry, are completed. 26,000 cubic yards of stripping have been cleared from the quarry, and 50,000 cubic yards of rock are ready for working. Concrete foundations at the crusher-site have been laid, and the necessary engines, crushers, hopper, and tipple erected and assembled. The erection of the bins is in hand. A number of huts have been erected to accommodate the quarry staff, and a cookhouse capable of boarding twenty-five men has been established. A ballast-engine has been transferred to this line, and it is anticipated that we shall now be able to proceed vigorously with the ballasting on the Tahora Section, as well as supply a considerable amount of stone throughout the Taranaki District, for which there is at present a fair demand. Opunake Branch Railway. Kapuni Section (0 m. 0 eh. to 7 m. 0 eh. ; length, 7 miles). —Formation on this section is now ready for platelaying, although a certain amount of widening and the taking-down of some batters still remains to be done. This work, however, will be carried out by the works train after the platelaying has been completed. The excavation carried out on this section during the period consisted of regrading formation from 1 m. 20 eh. to 1 m. 38 eh. in order to fit in with the road overbridge at Im. 22-40 eh. A great deal of water had to be contended with here, making the work difficult. Cutting and filling between 4 m. 60 eh. and 4 m. 66 oh. was completed, and the Kapuni station-yard at 6m. 56 eh. has been levelled, and is ready for platelaying. Work at the Waingongoro Bridge at 0 m. 25 eh. has been completed, including the underpinning of one of the piers which developed weakness after an earthquake. The erection of piers for the Kapuni Stream Bridge at 4m. 67 eh. has been completed, while the foundations for the Skeet Road overbridge at om. 42 eh. have been laid. An overbridge across the Skeet Road at Im. 22-4-0 eh. was built during the period. A start has been made with platelaying, and 34 chains of rails have been laid, together with a temporary siding for handling permanent-way material. The ballast-pit at Kaupokonui River has been stripped, and approach cutting, together with a river-diversion and piers for temporary bridge over the Kaupokonui River, has been completed, so that as soon as rails have been laid to this point a start can be made with the ballasting. A goods-shed has been erected at the Kapuni station-yard at 6m. 56 eh. Auroa Section (7 m. to 12 m. ; length, 5 miles).- Formation-work has been carried out vigorously on this section. The work has been treated as a relief work, and a large number of unemployed have been absorbed. The majority of the earthwork has now been completed; eight culverts have been built, together with side drains, and, generally speaking, the section is well in hand. Pihama Section (12 m. 0 eh. to 16 m. 40 eh. ; length, 4 miles 40 chains). —The work carried out on this section comprises clearing, fencing, culvert-construction, earthwork, and the erection of concrete-block platelayer's cottage at 16 m. 40 oh. in Pihama station-yard. Twenty concrete culverts and pipe culverts have been constructed ; fencing on the right-hand side has been completed from 12 m. to 13 m. 24 eh. ; 2 miles 60 chains of logging, stumping, and clearing have been completed ; and a number of cuttings are in hand. Opunake Section (16 m. 40 eh. to 23 m. 0 eh. ; length, 6 miles 40 chains). —Work has just been commenced on this section, and, in common with the previous sections, it is being utilized as relief works. The principal work done here comprises the erection of camps, carting of shingle for culverts, drainage, and a small amount of formation. Manaia Branch (0 m. to 5 in. 49 eh. ; length, 5 miles 49 chains). —Very little work has been done in this section during the year, what has been done being confined to the completion of the cutting from 2m. 70 eh. to 3m. 0 eh., and the construction of a private crossing at 2m. 68 eh. During the period further accommodation has been provided for the workmen by the erection of twenty-one single and two double huts. These huts were transferred from Tahora and erected on this work.

Nelson-Westland (North End). Kawatiri Section (59 m. 17 eh. to 63 m. 8 eh. ; length, 3 miles 71. chains). —The principal work on this section has been the driving of tho tunnel at 62 m. 43-85 eh., and the erection of the Hope River Bridge. A compressor plant was provided, but was not fully employed at the tunnel owing to the shortage of* men. During the latter portion of the year, however, better progress has been made, and 246 ft. of bottom heading was driven, the face now being at 62 m. 42-91 eh. The material in this tunnel is a very hard granite, broken with seams of quartz, and has so far been difficult to excavate. A number of tunnel blocks have been made, and shingle for the concrete aggregate, has been carted from the Buffer River for use in lining the tunnel. The piers for the Hope River Bridge have been completed ; the steel girders for both Hope bridges have arrived, have been carted to their respective sites, and are now ready for field riveting. A temporary bridge was constructed over the Hope River in order to deal with the spoil from the tunnel. Arthur's Pass Tunnel. The lining of the tunnel was completed in October, 1921. The 1001b. track is now laid from 51 m. 54 eh. to 58 m. 4-0 eh., with the exception of about 10 chains across the Rolleston Bridge. The platelaying in Arthur's Pass station-yard is well advanced, and should be completed in two months' time, with the exception of the portion to be done by the Railways Department. A. crushing plant with two crushers and steam-shovel was installed at Arthur's Pass, and with this and the aid of the small crusher at Otira tho line has been, ballasted and lifted with the first lift from. 51 m. 54 eh. to 58 m. 12 eh. The formation is completed, and a start has been made with the concrete kerbing for platform and excavation for subway at Arthur's Pass station-yard. The girders for Bealey Bridge have arrived, and six of these have been riveted up. The erection of the reinforced power-house at Otira was commenced in October, and should be completed in two months' time. Material for three Babcock-Wilcox boilers has arrived on the site, and these are now being erected. The bush has been cleared off the pipe-line from intake at Goat Creek to the power-house, a distance of 45 chains. A road has been formed to the intake, and a small dam erected, across Goat Creek. The excavation for aSO ft. circular reservoir, 90 ft. above the powerhouse, and. a 126 ft. by 60 ft. reservoir, 20 ft. above the power-house, are well in hand, and will be completed in one month's time. The contractors for the electrification have erected 6,000 cable-racks, and completed the erection of the lighting system in the tunnel. At the power-house a 10-ton travelling crane has been erected in the engine-room, and two 100 kw. lighting-sets, one battery booster, and three condensers have been installed. A quantity of switch-room gear'and pipes are on the site, but not erected. 1,500 railjoints have been bonded. At Arthur's Pass the sites for eighteen cottages have been cleared of bush and excavated for sixteen cottages ; 20 chains of road have been formed and metalled in the village. At Otira forty cottage-sites have been cleared of bush, fourteen cottages are now in course of erection, and a great deal of material is on the ground. Greymouth - Point Elizabeth Railway. Extension to Seven-mile (3 m. 45 eh. to 6m. 10 eh. ; length, 2 miles 45 chains). —The formation on this section has now been completed. The cuttings at 4m. 12 eh. and 4m. 45 eh. have been widened. The filling at 4 m. 33 eh. is, however, still subsiding into the swamp, and the above cuttings will require to be further widened to obtain material for this filling. Side drains have been excavated, and several pipe culverts put in. The station-yard formation was almost completed, and a temporary bridge was erected at the Seven-mile Creek. The concrete piers for the permanent bridge have been finished, and the ironbark piles for the abutments have been driven. The girders are on the sites, and as soon as the balance of the material is received the permanent work will be put in hand. The Raleigh Creek Bridge has been finished, and a reservoir to hold 25,000 gallons has been constructed. A water-race has been excavated, and a pipe bridge placed across Rocky Creek, to carry the watersupply to the station-yard. Platelaying has been completed to sm. 69 eh. on the main line, and 52 chains of siding have been laid. A ballast line was constructed to the beach, and the first and second lifts of ballast have been put in from 3 m. 46 eh. to 5 m. 68 eh. on the main line, and on 36 chains of sidings in the station-yard. Material is coming to hand for the erection of the station buildings. Lawrence-Roxburgh Railway. Beaumont-Miller's Flat Section (34 m. 70 eh. to 49 m. 70 eh. ; length, 15 miles). The construction of this line has been utilized to provide work for unemployed, and the work has consisted mainly in culverting and formation. Twenty culverts and concrete pipes have been laid, and the formation is more or less complete to 38 m. 60 eh. In places some of the banks have been kept narrow, and will be widened out eventually by means of a construction train. Three gangs are still

IRRIGATION. Ida Valley Scheme. During the season water was supplied to eighteen irrigators by means of about 50 miles of races. The Syndicate race extension has now been completed, but nothing further has boon done in connection with the drainage. The German Hill race has been enlarged from sm. 29 eh. to 12 m. 46 eh. Flumes at Moa Creek (0 m. 29 eh.), Maori Creek (7 m. 54 eh.), and Dovedale Creek (9 m. 36 eh.) arc in hand. A number of concrete culverts and private crossings, together with 68 chains of road-formation, have been completed. The German Hill race extension has now been completed from 12 m. 46 cl». to 22 m., but there is still a certain amount of culverting to complete, and this is being gone on with. Galloway Flat Scheme. Water has been supplied under this scheme during the past season to twenty-three irrigators. The revenue derived is not at present sufficient to cover outgoings, but the scheme is in its infancy, and the position will improve very greatly as the settlers become established. Olrig Terrace Scheme. This scheme has not yet been by any means fully developed, and at present only a comparatively small amount of water is being supplied by means of an old existing race. Excellent results should be obtained here with further development. Manuher[kia Scheme. During the year the concrete lining of the intake tunnel was completed, as well as the inlet and and intake gates, and a concrete gravel-trap at the outlet end of the tunnel. The concrete lining of the race in the Manuherikia Gorge has been finished. A number of concrete culverts and four large iron flumes have been completed, and all excavation is now in a finished condition. The Chatto Creek siphon, consisting of a double line of pipes, 1,800 ft. in length, and varying from 22 in. to 26 in. in diameter, was assembled, and is now in working-order. Distributory races HI, XYZG, CDE, and F have been completed. Ardgour Settlement Scheme. The surveys for the permanent line and siphons have been located, and the necessary plans prepared. Six miles of construction have been completed, and 5 miles are in hand. Fifteen concrete culverts have been installed, and 24 chains of race have been lined with concrete. The concrete intake and stop-gate are in hand. Earnscleugh Irrigation Scheme. This scheme has, with the exception of two concrete culverts, been sufficiently completed to supply all the land which has so far been taken up. It will, however, require to be extended somewhat as more land is occupied. General Surveys. Upper Manuherikia Scheme. —A detailed survey of the wall for the upper-dam site at Lauder has been made, and 60 miles of race have been levelled and pegged. Rough surveys have been made of the Falls and the Dunstan Creek dam sites, and trial race-lines have been run with a view to irrigating the northerly end of Ida Valley as well as the Manuherikia Valley, in all about 100,000 acres. Arrow River Scheme.- Preliminary surveys for a pipe-line, 3£ miles long, in the Arrow River gorge, to carry 48 heads and to irrigate about 6,500 acres on the Arrow flats, have been made, and a reconnaissance survey for 45 miles of race-lines and about 2 miles of pipe-lines has been made. Ida Valley Scheme.- Further investigations were made with a view to diverting water from Hope's Creek to the Manorburn dam, three different proposals being examined.

HYDRO-ELECTRIC WORKS. Arapuni. A. considerable amount of preliminary survey and investigation has been carried out on the site of these works. Preliminary surveys have been made for access roads from Putaruru. Exploration work near Pukeatua has been carried out, and drives put in to test the various outcrops of greywacke, and after a good deal of work suitable sites have been found for a permanent quarry to supply rook for the construction-work at Arapuni and for road-metalling. Alternative bridge-sites for bridging the gorge and head-race at Arapuni have been selected. Test-pits were sunk in the country on the spillway side, and information is being gathered in order to enable the Department to decide the best site for the power-house. Alternative plans have been prepared for a gravity arched dam, but the design cannot be finally settled until the talus has been excavated from the site. Regular gauge-readings were taken throughout the period under review, and further gauges were installed at the power-house site and at various points down-stream, in order to enable the tail-race levels to be investigated. Tests were made of the flow of the Waikato River, and calibrated with the readings on the gauge. A preliminary location for transmission-line from Arapuni to Te Kuiti was also carried out. Rotorua Electric Supply. Data were obtained and drawings made for alterations and extensions to the existing power-house and flume. A survey was also made for an alternative hydro-electric-power scheme to supply about 1,000 kilowatts. Exploration surveys were made between Whakarewarewa and Ngongotaha, in order to determine a site for power-house in which the motive power would be a Diesel engine which has been procured. A transmission-line route was also explored from Okere Falls to Rotorua. Horahora. Ruakura. —A new railway-siding has been laid at Ruakura to give access to the main substation, this, with the work inside the grounds, being done by this Department, whilst the Railway Department carried out the portion on their land. A transformer-house, test-room, and cottages Nos. 1 and 2 have been erected ; also new store, 30 ft. by 90 ft., with the necessary internal fittings, and a garage, 26 ft. by 46 ft., all in concrete. Te Awamutu. —The erection of the substation, 40 ft. by 20 ft., in concrete, is completed. Waihou. —A transformer-house, 30 ft. by 20 ft., has been erected. Horahora Headworks. —A considerable amount of work has been carried out at the generatingstation, principally in the direction of extending the crib-log and rock weir across the full width of the rapids. In addition to the actual work in the river, a considerable amount of work was involved in the provision and erection of tho necessary plant. A tramway had to be constructed, and a bridge, 87 ft. span, erected to bring up the stone to fill the cribs, which were constructed from timber grown a short distance away, floated into position, and then loaded. This crib-log weir, like the original portion constructed by the Waihi Company, is merely of a temporary nature, and. under its shelter the permanent concrete weir will be constructed when the river is low, probably during the coming summer season. Surveys have been made of the existing lay-out. New gauges were installed, and the zeros of all gauges checked. Waikaremoana Hydro-electric Scheme. The surveys of the construction pipe-line have been completed. Trial pits and borings have been sunk on the power-house site and at the main dam, and bearing-values determined. A detailed survey of the Waikare-Taheke River at the. site of the proposed dam was also carried out. An engineering survey of the main Waikaremoana Road, and a- land-plan survey of both access road reserves, were completed, and the proposed tram-line from the forest reserve to the main power-house laid out. The fencing of the southern boundary, extending from the Waikare-Taheke River to the Kahutangaroa Stream, was completed. Continuous gaugings of the lake-levels have been kept since May, 1921, and tests were undertaken to endeavour to ascertain the sources of the various subterranean streams flowing from the lake, but with not very great success. A measuring-weir was constructed at the lake-outlet, and a record of the discharge is being kept and compared with the rainfall records. The excavation for the pipe-line has been completed, and about two-thirds of the pipe-line have been laid and tested. The site of the power-house has been excavated and cleared, the foundations and all concretework have been finished, and, except for a few small matters, the power-house building is complete. A start has been made with the erection of the power-house bridge, the two main piers and south abutment having been constructed. A ropeway was erected at the end of the intake road for the transportation of the 24 in. pipes and other materials. A store and two temporary shelter-sheds have been built for housing stores and machinery. Two cookhouses have been erected.

Mangahao Hydro-electric Scheme. • No. 1 tunnel has been driven during the period a distance of 2,651 ft., of which 729 ft. has been completely lined and a further 270 ft. partly lined. The total amount driven to date in this tunnel is 3,361 ft. No. 2 tunnel has advanced 1,770 ft., of which 1,038 ft. has been completely lined and a further 400-ft. partly lined. In addition to this, 625 ft. of adit has been driven. The total amount of tunnelling to date under this heading is 3,496 ft. Considerable, delay was caused in progress of these tunnels by a strike of the co-operative parties over the first " wages-cut." In the foundations of the Mangahao Dam No. 1 6,000 yards have been excavated, and the by-pass tunnel heading has been driven 422 ft., the gate-shaft 78 ft., and the incline drive 52 ft. The start of this work was delayed for some considerable time owing to foundations not being so favourable as had been expected. The, same conditions were found at the Tokomaru dam, and the quantity of excavation here during the period was 7,500 cubic yards. Crushing plant and bins for concretework at both dams are nearly completed. The pipe-line excavation is approaching completion. Ninety concrete pedestals have been erected, and contracts have been let for the supply and erection of. pipes. A tram-line and 100 h.p. electric hauler for conveying the material up to the pipe-line has been completed and in operation for some months. Satisfactory progress has been made with the excavation of the surge-chamber, 8,000 cubic yards having been excavated. A start has been made with the erection of the power-house, the concreting of the tail-race being completed, the building itself in hand, and good progress generally being made. The crusher, screen, bins, and. concrete-mixer have been erected for use at the power-house. The work on the transmission-line is in hand, a large number of main-line and telephone poles having been delivered at the various railway-stations along the line, and erection contracts prepared for advertising. Six permanent cottages for the accommodation of the regular staff have been completed to date, and ninety-eight buildings, including single, huts, married men's quarters, cookhouses, recreation-halls, canteens, billiard-rooms, &c, have been erected for the accommodation of workmen. The sawmill has been in operation throughout the period, and all timber required on the works has been sawn locally. Lake Coleridge Power Scheme. The permanent work in connection with the diversion of the Harper River into the lake has been proceeded with, a large dam and a netted groyne having been constructed. This portion of the work is now practically completed, and a considerable improvement has taken place in the lake-level. The erection of the third pipe-line was completed and the fifth unit put into operation, and a contract was let for the erection of the fourth pipe-line, which was also completed during the period. The erection of the main transmission-line poles from Coleridge to Timaru was completed. Five miles of additional 11,000-volt reticulation was erected in the North Canterbury district, and 7£ miles of 33,C00-volt line, ■ * WAIHOU AND OHINEMURI RIVERS IMPROVEMENT.

APPENDIX D. o ANNUAL REPORT OP CHIEF ELECTRICAL ENGINEER. The Chief Electrical Engineer to the Hon. Minister of Public Works. Sir, — I beg to report on tho position of the development of electric power in the Dominion for the past year as follows : — The demand for electric power generally is still very urgent, both in the districts already partially supplied and in those in which a supply is not yet available. The, fall in prices of our primary products which took place during 1921 resulted in a financial stringency amongst the primary producers which rendered it necessary for them to look very carefully into the cost of conversion of their premises to electric working, and for the time being caused a check in the demand in many directions. But the check has been only temporary. The lower prices both for primary products and manufactured goods have necessitated every effort being made to reduce the cost of production. The supply authorities—particularly the Power Boards—have realized the difficulty with which the consumer is faced in financing the conversion to electric power owing to the reduction in prices and in many cases this has been met by the provision of a special loan to make advances to consumers towards the costs o| conversion. This is being largely taken advantage of by intending consumers and the demand for electric power for essential industries and for domestic supply is as urgent as ever. The power available is still generally deficient, owing to the delays which occurred during the war period in making necessary extensions to plant both in the State and in the local installations. Tho accessions to the gencrating-capacity of the electric-power stations of Now Zealand made during the year under review were the addition of one unit of 1,000 kw. at Invercargill (Borough Council, steam), and one unit of 650 kw. at Tauranga Borough plant (water-power), and of new local stations at Motueka (50 kw., gas), Kaikoura (37 kw., gas), Tamaki West (40 kw., gas), Havolock North (144 kw., water), Murchison (80 kw., water), Kaponga (90 kw., water). The total installed plant capacity of the generating-stations of New Zealand—omitting standby provisions—at the end of the year was 51,749 kw., as compared with 49,630 kw. at the beginning of the year. But every important station is beirrg extended, and orders have been placed for the following additions : — Kilowatts. Lake Coleridge (Public Works Department), water .. .. .. 6,000 Horahora (Public Works Department), water .. .. .. .. 4,000 Auckland (Eloctric-power Board), steam .. .. .. .. 13,000 Wellington (City Council), steam .. .. .. .. .. 5,000 Dunedin (City Council), water .. .. .. .. .. 3,000 New Plymouth (Borough Council), water .. .. .. .. 1,000 Pukekohe (Borough Council), gas .. .. .. .. .. 120 32,120 In addition, work is well under way for tho following new stations, which will all be in operation by 1925 :— Kilowatts. Mangahao (Public Works Department), water .. .. .. .. 20,000 Waikaremoana (Public Works Department), water .. .. .. 700 Monowai (Southland Power Board), water .. .. .. .. 4,000 Palmerston North (Borough Council), gas .. .. .. .. 900 Teviot (Power Board), water .. .. . . .. . . ■ ■ 250 Wairarapa (Power Board), water .. .. . . ■ . • ■ 300 Whakatane (Borough Council), water . . . . .. . . .. 300 Opunako (Power Board), water .. .. .. •. • ■ 120 26,570 By 1925 the electric power available in the Dominion will thus be more than doubled as compared with the present installed capacity. The growth in the installed capacity of electric - power stations of New Zealand since 1910 is shown in Fig. 4 herewith. The unsatisfied demand has for the whole period been substantially iir advance of the developed power.

B—D. 1.

D.— l

Industrial Developments. No marked changes have taken place in the industrial position since Mr. Parry's report of 1918. Electric power in dairying is making satisfactory progress. There are now about 548 electric milking plants in operation in New Zealand, distributed as follows : — Thames Valley Electric-power District . . .. .. .. .. 257 Te Awamutu Eloctric-power District .. .. .. .. 48 Cambridge Electric-power District .. .. .. .. 50 Central Electric-power District .. .. .. .. .. 59 Tai Tapu Dairy Company's district .. .. .. .. 36 °Eyre County . . .. .. .. .. .. .. . . 4 Rangiora County .. .. .. .. .. .. 32 Murchison County .. .. .. .. .. .. . . 4 Stratford District .. . . .. .. .. . . . . 8 Hawora District .. .. .. .. .. .. 50 Total .. .. .. .. .. .. ..548 This does not include any plants supplied from private installations of which no records are available. The largest use of electric milking will be in the electric-power district areas, only a few of which are yet supplying power, and when tho power districts now being formed are in a position to supply, this number will be largely increased. There are 12,468 power milking plants in operation in New Zealand, mainly driven by oil-engines, and as soon as the electric mains are available practically every one of those will be changed over to electric drive. The treatment of phosphates for the production of artificial manure has made important progress, owing mainly to the interest acquired by the Government in the Nauru Island deposits. During the year large treatment-works have been put into operation at Auckland and Christchurch —the first supplied with power in the meanwhile from its own steam plant and the latter from the Lake Coleridge system. These plants take 200 to 300 h.p. each, and thus constitute an important load. Works for the treatment of phosphates are now established in Auckland, Christchurch, Dunedin, and Invercargill. The Wellington District is not provided for so far, and it is anticipated that when Mangahao power is available this industry will also be undertaken in this district. One electric steel-furnace has been established during the year, supplied from the Lake Coleridge mains, and, after considerable difficulties of initiation, is now successfully converting pig iron into steel castings. A proposal has boon made to utilize 3,000 h.p. for tho smelting of Taranaki ironsands, and extensive and successful trials have been carried out in England on samples of the ironsands. Negotiations are now in hand as to a suitable source of electric power for this industry. It is anticipated that when the extensions and new stations rrow under construction are generally completed —say, in 1925 —there will be, on the whole, sufficient surplus of power to justify a campaign to develop the demand by encouraging the extension of existing industries and the establishment of new industries. Until this surplus is available the main advantage of electric power in attracting new industries cannot be realized. It is important that every development should be laid out and the capital expenditure arranged so that the installation will prove remunerative to the supply authority. But it is equally important, from the public point of view, that the layout in every case should bo. capable of extension at the smallest possible capital outlay up to the full capacity of the site, whether from water or steam power, in order to meet tho inevitable expansion in the industry. Owing to the financial stringency, the question of electrification of the suburban railways has made no further progress, though the electrification of the Otira Tunnel is in hand. A special powerstation with 2,400 kw. of steam-power and 250 kw. of water-power is being installed for this purpose. Automatic electric-power signalling for the railways has been introduced on the Wellington-Hutt lino, and it is proposed for other sections. Though small, the demand for power for this purpose will be important as the system extends. Saving effected by Water-power. With regard to the saving that is effected by the use of hydro-electric power, the actual costs of supply, including capital and operating costs of the power-stations in operation in New Zealand last year, were as follows : — Water. Steam. Gas. Oil. Number of stations .. .. 27 10 22 2 Average capacity (horse-power) . . .. 1,200 2,600 170 540 Average load-factor (per cent.) . . . . 48 32 (25*5 32-5 Capital outlay per horse-power .. .. £104 £69 £108 £84 Working-costs per horse-power year .. £6-1 £17 £23-4 £29-4 Capital charges per horse-power year .. £5.6 £6-9 £6J £6-5 Total costs per horse-power year .. .. £11 -7 £23.9 £29-5 £35-9 Compared with the water-power stations, at the same load-factor (48 per cent.), the fuel stations would have cost much more to operate. Moreover, the load-factor of most of the water-power plants can be largely increased at no increase in the cost of supply. There is thus a saving in the cost of supply from the twenty-seven existing water-power plants of New Zealand as compared with the ten steam plants of £12-2 per horse-power year, and as compared with the twenty-two*gas-engine plants of £17-8 per horse-power year. It must be noted that of these twenty-seven water-power plants more than one-half are old, small, and inefficient plants of 200 horsepower or loss, so that the comparison is not unduly favourable to water-power.'

D.—l

As compared with the cost of generating power by small steam or oil engines, now used in districts in which electric supply is not available, the saving is still greater. Each water horse-power operating on a 48-per-cent. load-factor supplies 4,200 horseqjower hour's per year. The same number of horsepower hours developed in numerous small steam-engines using an average of 9 lb. of coal per horsepower hour, worth £3 per ton delivered into the boiler, would cost £50-7 in fuel alone, showing, compared with £11-7 for water-power, a saving of £39 per year per horse-power of power-station output. Compared with small oil aird kerosene engines using 1 pint of oil per horse-power hour, costing 16s. per case delivered, the value of oil required to generate 4,200 horse-power hours is £52-5 pcr 1 year, as compared with the average cost of water-power of £11-7 —a saving of £40-8 per horse-power year. The actual saving in practice is about the average of these four figures- viz., £12-2 as compared with large steam plants, £17-8 as compared with gas-engine plants, £39 as compared with small steam-engines, and £40-8 as compared with, small kerosene-engines ; i.e., an average saving over the whole output of £27 per horse-power year. Of the average capital outlay of the water-power' systems of New Zealand- viz., £104 per horsepower -more than one-half is in the reticulation, which would be required in any case, leaving the capital cost of the power plant and transmission less than £52 per horse-power. The actual capital costs of the power-plant main transmission-lines and main substations in a few typical cases of hydroelectric stations are as follows : Lake Coleridge, £39 per horse power ; Waipori Falls, £32-5 per horsepower ; Horahora, £35 per' horse-power ; Wairua Falls, £29 per horse-power. The actual saving to the consumer after paying the whole cost of hydro-electric supply, including interest, depreciation, operating-expenses, maintenance, distribution and management charges at the actual average cost of the twenty-seven water-power stations of New Zealand —viz., £11-7 per horsepower year —is thus £27 per horse-power year, and is sufficient to pay off the whole of the capital cost. of the power plant within two years. The actual revenue of the water-power statioirs is only £13-2 per horse-power year, so that, of the £27 saving, the supply authority realizes only £1 10s. and the consumer the remaining £25 10s. But this is none the less a real saving to the community in reducing the cost of production by this amount. Ultimate Demand to be provided for. The ultimate demand to be provided for is a very important questioir which must be kept constantly in view in considering the development both of the large Government schemes and the smaller local schemes desigrrcd to supply the local demand until the comprehensive Government system is available. The basis of the general system laid out for the Dominion as a whole is a supply of 1 horse-power to each 5 head of population, or 0-2 h.p. per head. This was the basis laid down by Mr. Parry in 1918, and no reason has been found to depart from it. It is admittedly ample for all present purposes, but is not excessive considering the possible and probable development of electric cooking and special electrical irrdustries ; and in advantageous circumstances it is exceeded elsewhere. For instance, in Tasmania, with a population of 213,887 persons, the power already developed by the State iir its first water-power station at Waddamana is 66,000 h.p. —a provision of 1 irr 3-1 or 0-32 h.p, per head of population ; and work is now in hand on a supplementary station higher up on the Shannon River for 15,000 h.p., which will brirrg the proportion up to 0-38 h.p. per head. The justification for this large development is, of course, the sale of a single block of 30,000 h.p. to the Electrolytic Zinc Company, and of another of 5,000 h.p. for the manufacture of carbide of calcium. It is anticipated that the provision of a surplus supply of electric power in New Zealand would attract similar large industries here. In addition to this evidence, the following are the amounts of electric power actually installed in the various provinces of Canada as compared with the supply available in the four metropolitan districts of New Zealand : — Total Electric; Horse-power Horse-power per Head of installed. Population. Ontario .. .. .. .. .. .. 1,212,650 0-41 Quebec .. .. .. .. .. .. 1,015,385 0-43 British Columbia .. .. .. .. .. 305,31.5 0-58 Manitoba .. .. .. .. .. 97,247 0-17 Nova Scotia .. .. .. .. .. 46,948 0-09 Alberta .. .. .. .. .. .. 33,187 0-05 New Brunswick .. .. '.. .. .. 30,180 0-08 Yukon 13,199 3-17 Prince Edward Island .. .. .. .. 1,869 0-21 Saskatchewan .. .. .. .. .. Nil Nil. Canada (total) .. .. .. 2,762,880 0-31 Tasmania .. .. .. .. .. 66,000 0-32 New Zealand .. .. .. .. .. 74,000 0-06 Canterbury District .. .. .. .. 10,000 0-09 Dunedin District .. .. .. .. 8,000 0-11 Auckland City .. .. .. .. 17,200 0-20 Wellington City .. .. .. .. 10,000 0-12 The Canadian figures for the various provinces are particularly instructive, illustrating both the large proportion of power per head of population in the industrial provinces and the comparatively 1 small proportion in the purely agricultural and pastoral provinces. As compared with the proposed allowance for New Zealand of 0-2 h.p. per head of population, the large industrial provinces of Canada now use 0-41 to 0-58 h.p. per head, whereas the agricultural and pastoral provinces use from 0-05 to

D.—l

0-08 h.p. per head. The demand over the whole Dominion of Canada is 0-31 h.p. per head. The relative proportion of industrial to agricultural industries in New Zealand will be approximately the same, as in Canada, and the provision of 0-2 h.p. per head is thus a comparatively conservative provision. On this basis the allowance, based on the 1916 census, is 130,000 h.p. for the North Island and 90,000 h.p. for the South Island. Allowing for transmission and distribution losses and for normal increase, the total power now required is 160,000 h.p. for the North Island and 110,000 h.p. for the South Island. The Government Statistician forecasts a population of the Dominion in 1930 of 1,573,000, which on the one-in-five basis indicates a demand of 300,000 h.p. delivered, about 180,000 for the North Island and 120,000 for the South Island, plus the necessary allowance for standby plant and transmission losses.

The curve shown in Fig. 3 gives the output of electric power in the eleven western States of America in which the conditions arc generally fairly comparable with those in New Zealand, and a forecast to 1930, based on developments actually in hand {Journal of Electricity, vol. 46, p. 601). Fig. 4 gives similar curves for New Zealand, the forecast .up to 1926 being based on actual commitments and to 1930 on the development in view. This gives the following results : —

The forecast of the development is conservative, and will still leave irr 1930 an unsatisfied demand of 60,000 h.p. In fact, based on the experience in Canada and the Western States of America, a much larger development is required than is included in the present programmes of the Government and the present local authorities. Electro-chemical Industries. Apart from the normal development of the general systems of electric-power supply, the main justification for the development of the largest and most economical sources of New Zealand will be the establishment of large electro-chemical industries taking 10,000 h.p. to 30,000 h.p., such as the alkali and nitrate industries of Norway and Germany, or the zinc-extraction and carbide industries of Tasmania. There are several sites in New Zealand, particularly orr the western fiords of the South Island, quite as favourably situated for such industries, and it is important that these should be surveyed and the results advertised abroad, from whence the capital for these industries will come. Lake Coleridge Electric-power Plant. The year under review is the seventh year of operation, and, irr spite of the fact that serious turbine troubles developed, necessitating the calling into service of the steam standby plant, and entailing a period of restricted service, a small credit balance is shown after paying operating and capital charges. The year was again abnormally dry, but lake-level conditions were steadily improved as a result of temporarily diverting a portion of the Harper River into the lake (Fig. 6). Insulator troubles are still unduly frequent, but a decided improvement is shown as the original stock is weeded out and reiJaced by later designs of insulators. The plant operated under heavy overload throughout the year.

LAKE COLERIDGE HYDRO-ELECTRIC POWER SUPPLY CURVES OF MAXIMUM WEEKLY LOAD

D.—l

The capital outlay at the end of the year was £671,608, as against £499,957 at the beginning of the year. The revenue for the year was £56,814, being £1,498 in excess of all charges, including interest at 4| per cent, and depreciation at 2 per cent. Financial results of operation and load records are given in Table A herewith. The power-house maximum load reached 7,600 kw. on a rated plant capacity of 6,000 kw. — i.e., 26-7 per cent, overload —and an increase of 2-5 per cent, over the previous year. The output reached 37,929,750 units, an increase of 4-5 per cent, on that of the previous year. The annual load factor was 57-3 per cent., and the average weekly load factor was 62-9 per cent. The growth of load since the inception of the installation is shown in Fig. 5. Genera ting-costs per unit still show an upward tendency, being 0-02 d. in excess of the previous year's cost; but this increase should not recur, as it was more than accounted for by expenditure on maintenance of the temporary diversion of the Harper River and the demands made on the steam standby plant as a result of breakdown of two of the turbines. Extensions. —The erection of the third pipe-line was completed in July, and preliminary runs on the fifth unit made the following month, but, owing to trouble with the foundations and turbine, this unit was not put into service until April last. A contract was let for the fourth pipe-line of 52 in. diameter, and work commenced on it in November. Very satisfactory progress was made : the pipe-line has since been completed. A three-unit exciter of 330 h.p. capacity was completed and put into operation irr October. Work on the erection of the switching-station at Wind whistle for tho Timaru line tap-off was proceeded with, and orders placed for all the necessary switching equipment. In November a contract was let for the erection of the transmission-line poles from Windwhistle switch-station to Timaru, a distance of eighty-five miles, and this work has since been completed. A third transmission-line, from the power-house to Hororata, was put into service in February, and a commencement made on the reconstruction of the south main transmission-line from Lake Coleridge to Christchurch. The permanent diversion of the Harper River was commenced in the middle of August, a staff of thirty men being employed on this. This work is now completed. A 1,500 k.V.a. synchronous condenser was installed at Addington substation iir December, with great improvement to the service in general. In fact, without this it would have been impossible to carry the heavy overloads experienced. Power Boards were created to reticulate Banks Peninsula and Springs-Ellesmere Counties. The former completed and put into service the first portion of its system in December, and by the end of the year had completed the reticulation over fully one-half of the district. To supply this Board a 33,000-volt line has been run from Tai Tapu to Motukarara., and put into service temporarily at 11,000 volts. The Springs-Ellesmere Power Board has also commenced reticulation, and is already giving a partial supply. The 11,000-volt feeder was extended from Lincoln to the Selwyn River to supply this Board. A Power Board to reticulate and supply Ashburton district has also been formed, and is proceeding apace with the development of the reticulation. It will take supply from the Timaru line at Methveir and at Ashburton. The Department's 11,000-volt reticulation has been increased during the year from 77| miles to 821 miles. Connected Load. —The total connected load increased to 39,957 kw., as set out in Table D herewith, an increase of 16| per cent, on that of the previous year. The maximum demand on the substation was 6,720 kw., showing a diversity factor of 5-94. Operation. —The plant has been heavily overloaded throughout the year, the position being considerably accentuated by the breakdown of two of the turbine-casings. On the 24th October a crack developed in the casing of one of tire 1,500 kw. units, and during repair the available plant capacity was reduced to 4,500 kw., the steam standby plant being called into service. On the Bth November the new 3,000 kw. set was put into operation, but on the 27th it developed a crack almost identical with that which had occurred on the 1,500 kw. set. The steam standby plant was again called into operation, and in the meantime the casing of the first set sent to Christchurch for repairs. These were completed, and the set put into operation on the 21st December, when the whole load was again carried by the station. The casing for the sixth unit (3,000 kw.) arrived early in March, and was immediately installed in place of No. 5, and put into operation on the 30th of that month, bringing the capacity of the station up to 9,000 kw. Throughout tire whole period of trouble the public bodies and wholesale consumers co-operated loyally with the Department in its endeavour to maintain the service, and only this co-operation made it possible for the Department to carry out its obligations with a minimum of inconvenience to the general public. Transmission-system. —Three complete interruptions to service occurred during the year, orr each occasion the south line failing whilst the north line was under repair. The breakdowns iir question occurred—(l) 16th July, from 7.30 p.m. to 11.45 p.m. ; (2) 30th August, from 8.53 a.m. to 12.40 p.m.; (3) 26th February, from 5.18 a.m. to 8.51 a.m. The total period of complete interruption in supply for the year was thus eleven hours and a half, of which only four hours and three-quarters occurred between 8 a.m. and 5 p.m. —the ordinary industrial day. On each occasion the Tramway Board's standby plant of 2,000 h.p. was called upon and essential services were maintained. In addition to these three complete interruptions, single-lino breakdowns took place on fortythree occasions, involving the replacement of ninety-five insulators, or 1-8 per cent, of those in service and a breakage of the line wire on five occasions. Compared with experiences elsewhere, ranging from 10 to 20 per cent, of insulator failures per year, this record is satisfactory. With the replacement of the balance of the original insulators, manufactured in 1913, by modern types of insulators, and the replacement of the aluminium wire by copper wire of a larger section (19/13 S.W.G.), it is anticipated that these accidental interruptions will be reduced to a minimum.

D.—l

Water-storage. —Tho temporary diversion of a portion of the Harper River at the end of the preceding year resulted in a substantial rise in the lake-level, and a corresponding increase iir the available head at the intake in spite of the increased demand. At the end of the year the lake-level stood at 1,661-1 ft., as against 1,658-8 ft. at the beginning of the year, a rise for the year of 2-3 ft. (fig 6).

Industrial Developments. —Owing to the overloaded condition of the plant and the delay in getting the fifth generator into service restrictions were still in force at the end of the year, but were entirely removed on the final test of the fifth generator in April, 1922, which brought the plant capacity up to 9,000 kw. (12,000 h.p.). Since then supply has been given to the Canterbury Frozen Meat Company (making the fourth large freezing-works connected to the mains), Kempthorne-Prosser's new super-phosphate-works, the new woollen-mill erected by the Kaiapoi Woollen Company at Woolstorr, and several other consumers who had been waiting for supply. Moreover, the restriction on the use of ironing and heating points was removed, resulting in an increase of the city demand from 3,750 kw. to 4,290 kw. Future Extensions. —ln addition to the extensions now in hand, which will bring the plant up to the full capacity of the existing headworks —viz., 12,000 kw. (16,000 h.p.) —plans and specifications are in hand for a further extension, consisting of an additional tunnel, 11 ft. in diameter (as compared with the present 8 ft. tunnel), and an extension of the power-house to take at first two and finally three units each of 7,500 kw. (10,000 h.p.). This extension will provide for the whole of the water available from Lake Stream, the Harper River, and the Acheron River —in fact, the whole of the economical capacity of the site —and involves raising the lake-level from the present overflow level of 1,667-5 ft. to 1,670 ft. by means of a small outflow weir. Third Pipe-line Contract. —A valuable experience was gained during the year in a new form of contract for this work. During the war a great many works were let orr the basis of 10-per-cent. commission on the cost. This is an undesirable form of agreement, in that it gives the contractor every inducement to wasteful and extravagant expenditure. For the erection of the third pipe-line a tender was received in the following form : The Department to pay the actual cost (estimated in the tender at £8,500), and the contractor to receive a commission of £850, reducible by 15 per cent, of any excess in the actual cost over £8,500, and irrcreased by 15 per cent, of any saving below £8,500 in the actual cost of the work. As the next lowest tender was very much higher, and as the above arrangement gave the contractor every inducement to do the work at the lowest possible cost, it was accepted. The actual result was that a very hearty degree of co-operation was attained between the Department and the contractor, both being interested in keeping down the cost to a minimum ; and, after all services offered by the Department, such as electricity, transport, &c, had been charged up, the actual cost worked orrt at £7,184—a saving of £1,316 on the estimate —thus increasing the commission to the contractor accordingly, and giving a result eminently satisfactory to both parties. Waikato Electric-power Supply. The Horahora power plant has now completed its second complete year of operation since it was purchased from the Waihi Gold-mining Company, and the results have been very satisfactory indeed. The capital outlay at the end of the year under review was £353,808, as compared with £249,499 at the beginning of the year, an increase of £104,309. Of the total the sum of £212,500 represents the amount paid to the Waihi Gold-mining Company for the power-house and transmission-line to Waihi and substation at Waikino as taken over, and the balance, the amount expended on new lines to supply Hamilton, Cambridge, and Te Awamutu. The result of the year's operation shows a revenue of £28,207, against which are chargeable £7,986 working-expenses and £17,699 to cover interest and depreciation, leaving a net profit of £2,522, as compared with a loss of £6,282 in the previous year. The revenue has been derived as follows : Three mining services, £19,779 ; four dairy factories, £2,455 ; four Power Boards, £3,208 ; one borough, £1,391 ; rents, &c, £1,374 : total, £28,207. This satisfactory result is due largely to an increase of over £5,000 in the revenue from the mines, due mainly to the supply given to the Grand Junction Company at a very small additional capital outlay, and to the energy of the district staff in getting additional business elsewhere. But the provision of the 50,000-volt lines and substations necessary to supply future, requirements entails considerable additional capital cost. It is expected, that the general demand, apart from the mining load, in the district will increase sufficiently in a year or two to pay the additional capital charges, as well as the additional maintenance and working-expenses involved in these extensions ; but for the current year the revenue from the mining load has fallen off at a rate of £300 per month as compared with last year. The revenue from other consumers can hardly bo expected to increase sufficiently to offset this as well as the increased charges referred to above, so that unless the mining load and revenue recover the financial results for the current year will probably be less favourable. Arrangements have been made to supply the Railway Department with 400 h.p. to 600 h.p. for its large house-building factory at Frankton. Tenders, closing about the end if the year, are being called for an extension of the power-house capacity by 4,000 kw., making a total installed capacity of 10,300 kw., which is sufficient to utilize the minimum low-water flow irr dry years and allow one spare unit. To enable the whole of the lowwater flow of the river to be taken through tho head-race the extension of the existing weir across the river has been put in hand. It is proposed to reserve 2,000 kw. of this for supply to the Auckland Power Board. Sufficient material is on hand to enable the construction of the line to Auckland to be gone on with. The maximum load on the power-house has been 5,800 kw., which dropped, owing to reduction in the mining load, to 5,000 kw. at the end of the year. If the mining load increases again it is probable that the plant will be overloaded before the extensions above can be installed, but the supply contracts entered into with five of the large consumers who had previously installed their own steam plants permit the Department to make use of these plants if required, and if necessary to call on them to feed back up to 3,000 h.p. of steam power, so that there is no need to fear a shortage before the extensions now in hand are completed.

When completed the 50,000-volt system will consist of a ring main from Horahora via Hamilton, Waihou, Te Aroha, and Matamata back to Horahora, with single-line branches to Waikino and Te Awamutu, thus giving the advantage of an alternative lino to Te Aroha and Hamilton in case of trouble. This will assist substantially in ensuring continuity of supply to Waihi and Waikino. The 11,000-volt lines from Horahora to Hamilton via Cambridge and Matangi will then become 11,000-volt distributors for Cambridge, Matangi, and other consumers en route, as well as providing a third emergency feed of limited capacity from Horahora to Hamilton. In addition a 50,000-volt line is being surveyed from Horahora to Arapuni and on to Te Kuiti, which will probably be joined up later on to Te Awamutu, giving another ring main and an alternative route for that district. The, 50,000-volt to 11,000-volt substations at Hamilton, Te Awamutu, and Waihou are well in hand, the buildings- being completed and the transformers and switch-gear all delivered. In the meanwhile supply is being giverr temporarily at each point at 11,000 volts. Operation. —The power-house was shut down from 7 a.m. to 3 p.m. on the 28th, 29th, and 30th December to examine the race and to enable alterations to the screens to be completed. These alterations have been effective in preventing blockage of the screens, and no trouble has been experienced in operating the plant at practically full load. During the above hours of shut-down, power was supplied to essential, industries from the Grand Junction Company's steam plant at Waihi and dairy factory steam plant at Hautapu. The breakdown of condenser-bushings on the 50,000-volt oil switches necessitated these being cut out of service, causing some inconvenience in operation. The only line breakdowns during the year consisted of three pin insulators and two sets of strain insulators, which was replaced. In order to reduce the electrostatic strain on the insulators, which are now over ten years old, the transformer neutral at the power-house has been earthed, and forrr elements instead of three inserted in the strain insulators. It is expected that these changes will render tho service still more reliable. The- painting of all towers from the ground up to the telephone cross-arm was completed during the year. Examination of the towers showed that they were generally in good order. A number were painted from the telephone cross-arm up to the top during tin; three days shut-down at Christmas week, but the time available for cutting power off for this work" is small, and bad weather made it impossible to do much this year. Apart from the shut-down for overhaul for three days during the Christmas holidays for a total time of 31 hours 20 minutes, power was off the 50,000-volt linos owing to accidental interruptions on seventeen occasions for a total period of 35 hours 6|- minutes, and on five occasions, at prearranged hours, for minor repairs for a total time of 11 hours 16 minutes. Most of the above accidental stoppages were momentary, only two being of more than one hour's duration. One on the 2nd January was for a period of 11 hours 46 minutes, and one on the 2nd March for 22 hours 12 minutes. The Grand Junction Company's steam plant provided standby service on both these occasions. There was only one interruption on the 11,000-volt lines due to insulator failure, one strain insulator having broken down, due to lightning. There were a number of momentary interruptions due mainly to lightning and birds causing grounds, and thus opening the circuit-breakers ; arrd also a number of prearranged stoppages, amounting in all to about, fifty hours, to allow of work being done on the lines, new consumers being connected, or new apparatus installed. Mancaiiao Electric-power Supply. This plant will have an ultimate capacity of 24,000 h.p., the whole of which is included in the first installation, consisting of three 6,000 h.p. and two 3,000 h.p. pelton wheels, operating at a head of 825 ft., and driving generators operating at 11,000 volts, three-phase. The energy from these will be stepped up to 110,000 volts by means of two banks of transformers, each of 12.CC0 kw. capacity, for transmission to Wellington, Bunnythorpe, Marton, Dannevirke, Pahiatua, and Masteiton. In Wellington the distribution will be undertaken by the City Council, which is already supplying 11,000 lighting and 7,000 heating and power consumers with a maximum load of 3,ECO kw. on.lhe A.C. system, and 3,300 kw. on the D.C. tramway-power system. Irr the other districts the distribution

will be undertaken by Electric-power Boards, of which seven are already constituted, covering the whole area which'can be reached from Mangahao and the whole of the available power, which has been allocated as follows : — _ ~. Horse-power Population. a U ooe S e d. Wellington District .. .. ~ .. .. 93,030 12,000 Hutt Valley Electric-power District .. .. ..22,594 2,000 Horowhenua Electric-power District .. .. .. 12,000 1,200 Manawatu-Oroua Eloctric-power District .. .. 36,642 3,300 Rangitikei Electric-power District .. .. ..12,222 1,800 Wairarapa Electric-power District .. .. ..22,159 2,000 Tararua Electric-power District .. .. ..10,090 1,000 Dannevirke Electric-power District .. .. ..13,082 1,300 24,600 Negotiations are now in hand for the supply to Wellington City. The Power Boards covering the balance of the district to bo supplied have all been constituted, and are making provision for the erection of the necessary reticulation in each case, but have not yet entered into contracts for the supply of the necessary power. The above allocations of power available from Mangahao* are only one-half of the ultimate demand anticipated from each district, and the full output of the plant is thus assured apart from any agreements to take power. In fact, Mangahao will be overloaded and will require supplementing from other sources as early as when the Lake Coleridge plant has reached the same position, It is anticipated that, pending the installation of the largo plant at Waikaremoana for this purpose, this relief will be available from the steam stations being installed by the Wellington City Council at Evans Bay (1.0,000 kw.) and by the Wanganui Borough Council (1,750 kw.). Arapuni Electric-power Supply. The proposed installation at Arapuni consists of an ultimate equipment of twelve units each of 12,000 h.p., of which eight are roqrrired to complete Mr. Parry's scheme (96,000 h.p.). The first installation proposed will consist of four of these units (48,000 h.p.), and the plant will not pay its way until the load reaches about 36,000 h.p. In the meanwhile the load will be built up by means of the Horahora plant (14,000 h.p.) and Auckland City steam-power plant (26,000 h.p.) and smaller installations at Te Kuiti, Huntly, Ngaruawahia, Pukekohe, Tamaki, and Rotorua, amounting irr all to about another 1,000 h.p. But the Arapuni works are in an entirely different position from Lake Coleridge and Mangahao, in that without the Auckland City load (estimated to reach 26,000 h.p. by 1928) it was impossible to develop the scheme on a commercially sound basis. Tt was therefore necessary to arrange a definite contract with tho Auckland authorities before putting the works at Arapuni in hand. This was accordingly done. This contract anticipates that the Auckland Electric-power Board, which has taken over the obligations, will have a demand of at least 15,000 kw. (20,000 h.p.) in 1928, when the works are expected to be completed. The Board is extending its existing steam plant from 6,500 kw. up to 19,500 kw. capacity, and it is now anticipated that this plant will be loaded up to 16,500 kw. by 1925. Allowing one unit of 3,000 kw. as spare, this is considered the full load of the plant, and it is anticipated that the load will grow considerably in excess of this by 1928, if power is available. * Waikaremoana Electric-power Supply. The ultimate development proposed at this site will consist of three power-houses, taking the regulated flow from the lake of 540 cusecs, and giving the following outputs on a 50-per-cent. loadfactor :— Horse-power. Upper power-house (450 ft. head) .. .. .. .. .. 40,000 Middle power-house (675 ft. head) .. .. .. .. .. 60,000 Lower power-house (344 ft. head) .. .. .. .. .. 30,000 Mr. Parry's scheme requires only 40,000 h.p. at this site, for which the middle power-house will be installed, being the most economical. In the meanwhile a small temporary plant has been erected for construction purposes and to give a supply to the. Wairoa Electric-power Board. For this purpose the two three-unit exciters with their synchronous motors and water-wheels each of 500 h.p. capacity, intended ultimately for the main power-house, have been installed, the motors being operated as generators, giving a capacity of 1,000 h.p. . An arrangement has been entered into with the Wairoa Power Board to operate the plant and supply power to the Department as required for construction work- orr the main plant. Supply will be available within a few weeks. Apart from this small plant, the greater portion of the capital outlay has been expended on the permanent improvement of the road and bridges to give access to the main power-house site and pipe-line intake, tho road in tire meanwhile serving also to improve, the access for tho settlers of the district. Surveys for the main scheme and foundation investigations have also been carried out, as well as a survey for a sawmill tram-line. Continuous river and lake gaugings have been made during the year.

Electric-power Bo aim is. The retriculation of the electric power supplied in bulk from the Government power-stations is intended to be undertaken by the Electric-power Boards, arrd twenty-three such Boards have irow been constituted, as detailed in the attached table. These cover a total area of 31,141 square miles, or 30 per cent, of the area of the Dominion, and include a population of 470,087, or 38-5 per cent, of the total population of the Dominion; so that about one-third of the Dominion is provided for by the Power Boards already formed. The subdivision of the whole Dominion into suggested electric-power districts as outlined in the last Statement provides for forty-one districts, and nineteen of the above twenty-three correspond closely to the subdivisions proposed.

Electric-power Boards of New Zealand as constituted on 1st September, 1922.

In addition to the twenty-three districts already constituted., petitions have been circulated or other preliminary steps taken to constitute Electric-power Boards in the following districts : — Population. (Squ^. e °Milos). Waipawa .. .. .. .. .. ... 8,534 1,235 Tauranga .. .. .. .. .. ..6,197 651 Marlborough .. .. .. .. ..16,967 437 South Canterbury .. .. .. .. .. 40,657 5,100 Otago .. .. .. ... .. ..108,604- 4,126 TeKuiti .. .. .. .. .. .. 8,568 1,115 Selwvn .. .. .. .. .. .. 10,455 2,281 Grey Valley .. .. .. .. .. 11,953 1,452 Otago Central .. .. .. .. .. 5,121 2,684 Wairere Falls Totals .. .. .. .. 217,056 19,081 With regard to the sources of supply of the twenty-three districts constituted, four are now taking supply from Horahora,, three have arranged to take supply from Lake Coleridge, seven propose to take supply from Mangahao, one has arranged to take supply from Arapuni, one has arranged to take supply from Waikaremoana, three have arranged to construct their own power-stations, and four have not yet decided upon their source of supply but will require to make their own arrangements : that is to say, sixteen out of the twenty-three have been formed to take supply in bulk from the Government, and the other seven will probably also take such supply as soon as it is available. Out of the twenty-three districts sixteen have already laid out their schemes of reticulation and taken their loan polls. The total amount of the loans is £4,886,500. This amounts to 5-4 per cent, of the unimproved rateable value of the districts concerned, and £14 per head of population of the districts concerned. It is anticipated that each Board will so arrange its scale of charges that the whole of the annual costs, both working-costs and capital charges, will be paid out of the, revenue received from consumer's ; but if the whole of the interest at an average, rate of 6 per cent, were a charge against rates it would amount to about |d. in the pound on tire unimproved value, arid proportionately less on the capital value. It will be noted that the loan polls in the various districts have been passed by an average majority of fifteen to one —in other words, the ratepayers have been practically unanimous in approval of the loans.

Of the twenty-three districts constituted the majority have included the whole of the area concerned as rateable inner area, the presumption being that it is intended to supply over the whole area as soon as it proves remunerative to do so : these are, particularly, Southland, Thames Valley, Banks Peninsula, Central, Wairoa, Springs-Ellesmere, Auckland, Manawatu-Oroua, Dannevirke, Horowhenua, Tararua, Hutt Valley, and Buller Power Districts. Five others —viz., Te Awamutu, Cambridge, Teviot, Opunake, Reefton —have limited their area to a small district, the whole of which it is intended to reticulate. The remaining five districts—viz., Ashburton, Wairarapa, Wanganui-Rangi-tikei, Taranaki, and Westland. —have taken advantage of the provisions of the Act for including the more sparsely settled districts as outer areas, only the more closely settled portion being included irr the rateable district at present. But provision is made in the Act for the inclusion of additional areas in the rateable district on petition, and this has already been taken advantage of in two cases. On the whole, the legislation, as far as can be judged at present, is proving quite successful in relieving the Government of the detail work of reticulation, in throwing the responsibility of this reticulation on to the shoulders of the local ratepayers, and leaving to the prospective consumers, as ratepayers, the decision as to which areas can be reticulated remuneratively and which should be postponed until the prospects are more promising. Local Electric-supply Systems. Including tire Government stations, there are now sixty-one electric-power stations irr operation in the Dominion, as detailed in Tables X and L herewith. Four new stations commenced operation during the year under review, viz. : M.ofueka (50 kw., gas-power); Kaikoura (37 kw., gas-power); Tamaki (40 kw., gas-power); Murchison (80 kw., waterpower). The following will commence operation during the current year : Fairlie (40 kw., waterpower) ; Havelock North (144 kw., water-power); Whakatane (250 kw., water-power); Opunake (120 kw., water-power) ; Teviot (250 kw., water-power). Extensions were made to existing stations during the year as follows: Invercargill. (1,000 kw., steam-power); Tauranga (650 kw., water-power); Kaponga (90 kw., water-power); Raetihi (32 kw., water-power); Hawora (180 kw., water-power); Oamaru (150 kw., gas-power) ; Patea (40 kw., water-power) ; Martinborough (50 kw., gas-power) ; Stratford (90 kw., oil-power). In addition extensions and new stations are in hand to the extent of 32,000 kw., as already detailed. The. sum of the maximum outputs of all stations has increased during the year from 42,157 kw. to 48,866 kw., an increase of 6,709 kw., or 16 per cent., and the number of consumers in tire Dominion has increased from 73,151 to 88,838, an increase of 15,687 consumers, or 21 per cent. The total installed capacity of the sixty-one power-stations has increased from 49,630 kw. to 51,749 kw. of main plant, and is distributed according to source as follows : — Stations. Kilowatts. ''~ , nor Cent. Water-power .. .. .. ..27 25,125 49 Steam-power .. .. .. ..10 22,470 43 Gas-power .. .. .. .. ..22 3,343 6-5 Oil-power .. .. .. .. ..2 811 1-5 61 51,749 100-0 In addition there are 7,247 kw. of subsidiary or standby plant, distributed as follows : Waterpower, 110 kw. ; steam-power, 4,753 kw. ; gas-power, 310 kw. ; and oil-engines, 2,074 kw. The total of tho maximum loads was 48,866 kw., as compared with the installed capacity of 51,749 kw., apart from the 7,247 kw. of standby plant, showirrg a margin in main generating plant of 2,883 kw., or 5-6 per cent, of the installed capacity. The water-power plants as a whole were actually overloaded by 500 kw., and the extensions in hand are thus urgently required to meet the increasing demand. The load-factor for the year, based on a maximum load of 48,866 kw., and an output of 171,943,546 units, is 4-0 per cent. ; and the load-factors for each type of plant are—Water-power, 48 per cent. ; steam-power, 32 per cent. ; gas-power, 25-5 per cent. ; oil-power, 32-5 per cent. These figures in each are high, due to the extensive use of electric power for tramways, industrial, and domestic purposes. The units sold per consumer (exclusive of tramways) was 1,210 units, as compared with 1,246 units per consumer in the previous year. The maximum demand per head of population in the areas actually supplied was 0-067 kw., or 0-089 h.p., inclusive of tramways, and the units sold per head of population were 146, exclusive of tramway load. Both of these figures show an increase over the previous year. The total length of distribution-line is 2,814 route-miles (apart from 400 miles of transmissionline), as compared with 2,260 miles in the previous year. The power-demand supplied per mile of line was 14 kw., the sales 38,500 units, and the revenue £327 per mile, excluding tramways in each case. The number of consumers per route-mile of line is 31-4, as compared with 32-3 last year. These figures are of considerable importance in considering the question of the construction of new lines, and the probability of their proving as remunerative as the average returns from the existing lines of the Dominion. It is usually considered that country lines costing £250 to £300 per mile will pay with two farms connected per mile, each with a milking plant, and taking a maximum demand of about 4 kw., yielding a revenue of £50 per year or more per mile of line. The average return (excluding tramways) was £24 per kilowatt of output also a very important figure in estimating tho return from a new plant. It will be noted that this includes the lower return of £17-6 per kilowatt from the large water-power plants. The steam, gas, and oil stations, which represent average retail conditions, show a revenue of £33-7 per kilowatt of output, which is the figure

D.—l

which may be taken in forecasting the return from ordinary general retail busirress, excluding such large consumers as freezing-works, &o. The revenue per kilowatt from the twenty-two gas-engine stations is £41 per kilowatt of output, and from the output of the two oil-driven stations is over £52 per kilowatt; but these are obtained at high retail rates, ranging frorrr Bd. to Is. for light and 3d. to sd. for power, as compared with usual retail prices of 6d. and 7d. for light and l|d. to 3d. for power. Out of the total number of sixty-one stations and twerrty-ono bulk distributing authorities, twenty-seven made a loss last year, as compared with thirty which incurred a loss in the previous year. Costs are now falling again, and it is anticipated that hereafter only those that are in the first two or three years of operation will show losses. Over the whole Dominion the electric-supply business involves a capital outlay of £5,224,629 for an installed capacity of 51,749 kw. — i.e., £101 per kilowatt; and the revenue, after paying all working-expenses (£534,642) and capital charges, including depreciation (£305,838), which work out at an average of 5-85 per cent, on the capital outlay, yields a net profit of £82,688, or f-6 per cent, on the cajrital outlay. The business on the whole is thus remunerative, as well as supplying a public necessity to 88,838 consumers. The table herewith gives a full analysis of the results of operation of the sixty-one stations, separating the returns from water-power, steam, gas, and oil stations. The most significant figures are, of course, the low costs per unit and per kilowatt output of the water-power stations. It must be noted that these figures include the returns from a number of quite small water-power plants, only five out of the twenty-seven installations beirrg over 1,000 h.p. capacity. The comparison of the capital cost per kilowatt is also instructive. In comparing the costs of the steam and gas stations it must bo noted that the average size of the ten steam stations is sixteen times as large as the average size of the twenty-two gas stations, and this has more to do with the higher working-costs of the gas stations than the nature of the fuel. On the same average size of plant the gas stations would probably show a better result than the steam stations, It is noticeable that the publication of these details of each of the power-stations of the Dominion is already resulting in a very healthy competition between individual statiorrs to show good results, to the substantial benefit of the public.

Cambridge Power Board (exterrsiorrs). The number of route-miles of electric Hires at the end of the year under review is approximately 3,200. With the constitution of the seven electric-power districts in connection with Mangahao, together with Ashburton, South Canterbury, and Southland, and other Power Board areas, all being reticulated in the, near future, the volume of the work will necessarily be considerable for some time to come. During the year steps were taken to inaugurate a " safety campaign " in connection with the general use of electricity, and advantage was taken of the columns of the School Journal to broadcast some information on. the care and use of electrical appliances, and the dangers in unauthorized interference with same or in touching any broken wires lying on the ground, &c. It is anticipated that this avenue of giving publicity to the need for safety precautions will produce good results in educatirrg the rising generation, concurrent with the increasing use and applications of electric power. All local authorities throughout the Dominion were also circularized drawing attention to the prevalence of electrical accidents. A list of the electrical accidents which have occurred in New Zealand during the past twenty years was compiled from existing records on this Department's files, totalling sixty-seven accidents, of which thirty-three were fatal, and this was distributed to all concerned. The various electric-supply authorities are becoming alive to the necessity of constantly keeping before the public the risks which exist if proper precautions are not observed, and have adopted various methods of propaganda accordingly. Licenses for the erection of electric lines were issued to soverrteerr public bodies during the year, each involving a detailed investigation of plans, and numerous inspections were made of the plans of proposed hydro-electric works submitted under the regulations. Australian Works. An opportunity was afforded to me during the year to visit Australia and to look into the construction and organization of the corresponding works there. In Sydney the general features of the large electric-power plants at Ultimo, White Bay, and Pyrmont proved very useful. The White Bay plant of the Railway Commissioners consists of three 10,000 kw. steam turbines, and runs at an operating-cost below 0-2 d. per unit, consuming less than 2 lb. of coal per unit, costing £1 ss. per ton in the power-house bunkers. The circulating-water system and boiler-room equipment of this station are of special interest. The control-room and oil-switch layout are also very carefully designed. Tho control-room is practically separated frorrr the engine-room, having direct communication only by a bay-window so high up and remote from the generators that all communication must be by telephone and electrical signals. In Ultimo powerhouse the old. high-tension switchboard, now situated on a gallery in the engine-room, is to be removed, and replaced by a remote-control switchboard located in a similar operating-room shut off by windows from the engine-room. At Newport (Victorian Electric Railway) power-station the operating-room containing the switch-panels is entirely removed from the engine-room, and, it is claimed, with advantage in operating. In New South Wales I also visited the Port Kombla steam station (3,600 kw.), which is being developed by the State Government to supply power for constructing the Cordeaux and Avon dams and for permanent power-supply in the district. The most interesting feature of this station is the fact that every circuit is metered with a printometer meter, giving a perfect automatic record of the station output and its distribution. At Port Kembla 1 took the opportunity of examining the processes of copper refining and manufacture into wire and cable, and the Cordeaux and Avon concrete gravity dams in course of construction. The Cordeaux dam will be 177 ft. high above foundation—about the same height as the Arapuni dam —but will be much lorrger (1,315 ft.) owing to the flatter nature of the valley. It is a gravity section containing about 220,000 cubic yards of concrete, estimated to cost £675,000 complete. In Melbourne I got into touch with the development of the Victorian Electricity Commissioners at Morwell brown-coal fields, consisting of a 60,000 kw. steam plant and an eighty-mile transmission at 130,000 volts, and also the Newport power-house of the Melbourne Electric Railways. This station consists of six steam-turbine units, each of 10,000 kw. to 14,000 kw. capacity, and contained many details in tho boiler-room, engine-room, and switch-chambers of great value. The details of the Melbourne Electric Railway overhead construction and rolling-stocks and workshops were also instructive. Although they have had about 200 motor-car equipments, each consisting of four 150 h.p. motors, in service for about two and a half years, only two armature breakdowns had occurred in that time and a few field breakdowns. The operation of the electric trains generally has proved efficient and economical, and has increased the passenger-carrying capacity and the comfort of the railways very much. In Adelaide I examined the tramway and lighting power-stations, and the plans of the new power-station under construction at Port Adelaide, designed for 10,000 kw. units. In Sydney and Adelaide I examined the working of the electric steel-smelting furnaces closely. These are both small single-phase furnaces, 7 cwt. and 15 cwt. capacity, taking 200 kw. to 300 kw., and are provirrg very successful indeed. In Broken Hill and Port Pirie I got into touch with the mining concentrating and smelting industries, which, give the raw material for the electrolytic zinc industry which forms the basis of the Tasmanian hydro-electric-power scheme. At Port Pirie the Government wharf-cranes for handling the coal for Broken Hill and the concentrates from Broken Hill were particularly interesting. Fifty men were employed, and it is a rare example of a large wharf worked entirely by permanent labour. By keeping general repair work- in hand the men are all kept fully employed without lost time, aird only twice in four years have men been laid off owing to shortage of work, and that due to stoppages of work at the mines.

In Tasmania the Government hydro-electric scheme offered much valuable information, as the details of the development are similar in many ways to our own developments. The, Great Lake dam is a multiple arch dam. of twenty-nine spans of 40 ft each, and a maximum height from foundations of 80 ft. The area of the lake is 50 square miles, tho watershed 216 square, miles, and the capacity of the dam at 11 ft. draw-off is 315,000 acre-feet. The pipe-lines, both wood-stave and steel, are special features. The four wood-stave pipe-lines are each over a mile long, and run down to a maximum head of 400 ft., the pipes being 4 ft. and 5 ft. in diameter. The steel pipes are, gas-welded pipes with muff joints, and the total head is 1,130 ft. or 480 lb. pressure. The power-house is equipped with nine pelton wheels and generators, of a total capacity of 66,000 h.p. The transmission-lines to Hobart are carried on two lines of double-circuit steel towers, a distance of sixty-two miles, at a pressure of 88,000 volts. Many of the details of construction and experiences of operation gained in Tasmania will be of the utmost value in putting the new lines into service here. The two main consumers of the power are the Electrolytic Zinc Company, who are now taking 15,000 h.p., to be increased under contract to 30,000 h.p., for zinc-refining, and the, Elcctrona Carbide Works, now taking 2,500 kw. to be increased to 5,000 kw., for the manufacture of carbide of calcium. The huge carbon electrodes for the carbidefurnaces are each 20 in. by 15 in. by 7 ft. long, and. are made, on the premises by means of a 3,000 ton press. In the trials of electro-chemical industries in Christchurch during the war the production of the necessary electrodes proved the main stumbling-block. In addition to the above main works numerous smaller works and industries wore visited and noted in detail. In addition to the opportunity of visiting engineering and industrial works, the visit enabled me to get into direct touch with the development and organization of electric-power supply and distribution under four distinct systems of control, viz. : (1) By a branch of the Public Works Department in New South Wales ; (2) by a special Government Department set up for the purpose in Tasmania ; (3) by a special Electric-power Commission responsible direct to Parliament in Victoria ; (4) by private enterprise in South Australia. AH four are meeting a very large demand, and facing such developments as are before us in New Zealand, and the organizations which are actually meeting the demand most effectively are the Electric-power Commission of Victoria and the Hydro-electric Department of Tasmania. The visit proved most valuable, and it is very essential that the members of the staff engaged in the detail design and layout of the hydro-electric works should have opportunity from time to time of making similar visits to tho corresponding works being carried out in other countries, particularly America, Sweden, and Switzerland. Staff. The hydro-electric work, of the Dominion has developed rapidly, and the present staff deserve the highest commendation for the loyal and efficient manner in which they have coped with extra duties ; but the personnel will have to be materially supplemented to maintain the efficiency that is imperative with the growth of this important work. "A few additions have been made, and two officers made prolonged visits to America for the purpose of gaining experience, with most satisfactory results. However, urgent work is waiting to be done, and it will be necessary to obtain additional experienced officers in this class of work at an early date.
