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

Mr. Speaker,— In submitting my second Public Works Statement I have to announce a very different state of affairs to that which existed twelve months ago. Last year the work of my Department was delayed and rendered unusually expensive through scarcity of material and the difficulty of procuring suitable labour. The latter circumstance was due to the fact that almost all employers of labour, who had of necessity been restricted in their operations during the war, had launched out vigorously again on various necessary works. Consequently the Department had great difficulty in making the progress which was desired. A higher rate of wages, improved conditions of living on the works, more and better mechanical appliances, and the rearrangement and encouragement of the staff were factors which helped the Department to overcome the difficulties and maintain an improved rate of progress. Conditions now are quite different. The supply of material and labour is considerably greater than funds will permit me to utilize. Still, the improvements in working-conditions and the reorganization that has proceeded should bear fruit. Wherever possible work is being carried out on the basis of payment by results, with appreciable benefit both to the workmen and to the Department. Last year I announced that certain departmental reorganization was considered advisable to decentralize the administration as much as possible and place more direct responsibility on the District Engineers, with the object of expediting work. This policy has been put into operation, with marked improvement in administration. A large quantity of labour-aiding machinery has now been installed with very beneficial results. So far the staff and workmen have not reached the maximum results, but already a very large improvement in output is apparent, and, as those directly engaged with the plant become more accustomed to the altered conditions which it brings about, still better results may be confidently anticipated. Legislation has been framed with the object of improving the construction and maintenance of the arterial roads of the Dominion. This should occupy a prominent place in future legislation, as it is a subject that demands as urgent attention here as it is now receiving in practically all the most progressive countries in the world.

I refer later on in this Statement to a new system which is proposed in connection with appropriations for roads and bridges. Under this system the money available for roads and bridges will be spent to the very best advantage, and where it is most urgently needed in the development of the Dominion. Much attention is being given in other countries to the subject of road improvements in relation to motor traffic. With the development of this means of transport th§ value of good roads cannot be overestimated, and future railway construction must be considered in the light of possibilities in this respect. The experience of some countries goes to show that satisfactory communication can sometimes be provided by motors on good roads in less time and at considerably lower cost than by railways ; and this new factor in the development of the country must be kept in view. During the war period the purchase of bridge material, rails, and sleepers was restricted as much as possible, and our stocks became depleted. Heavy expenditure has therefore been necessary for large quantities of material during the year ; in fact the total public-works expenditure for the twelve months has been greater than at any period in the history of New Zealand. On railways it exceeded the record of the past forty years, while on hydro-electric development it was two-and-a-half times greater than in any previous year. The present financial circumstances demand that expenditure must be reduced; work can be undertaken only according to the money available. Last year I announced a policy of concentration in regard to rail way-works. A perusal of this Statement will reveal that this principle has been followed, though not as far as I had hoped. It will be adhered to in future ; and I again emphasize the necessity and wisdom of such a course. It was not possible or reasonable during the year to discontinue work on many lines; the Kaihu Valley line, the Waiuku Branch line, the Tahora Section of the Stratford - Main Trunk line, and the Otago Central line, for instance, were so nearly finished that common-sense demanded their completion. The Waipu Branch was discontinued for a time, though certain work was afterwards done there. No work has been or will be commenced on the Waikokowai or Waipa gravelpit access lines. The Waihi Eastwards will be suspended when Athenree is reached, but possibly financial considerations will necessitate an earlier cessation. Work from Tauranga westwards had been suspended, except in the vicinity of the wharves and station. Work on the Wairoa-Gisborne Section has been stopped, and a halt will be called at an early date on the Ngatapa Section of the Gisborne-Wairoa line, except in regard to maintenance and preliminary work on the tunnels. No further work has been opened up on the Napier end of the East Coast Railway, but efforts have been directed to finishing the first length so that work on this line also can be stopped. Work on the Waimate Branch Railway was discontinued. Otago Central Railway was completed to Cromwell and discontinued. Thus, in accordance with the policy of concentration, work on five lines has been suspended, while on four construction was so far advanced as to enable them to be completed this year. With due regard to the money likely to be available for 1921-22, it was necessary to suspend operations on eight additional lines, though in order to make provision for possible unemployment sums will be allocated for certain works distributed over the Dominion. The works upon which effort will be concentrated will be the Midland line, North Auckland connection, and the East Coast Main Trunk; but financial provision will also be necessary for the completion of the Waikokopu Branch (the excavation work being now nearly finished) and for the Stratford - Main Trunk as far as Matiere. EXPENDITURE. The expenditure for the financial year ended 31st March, 1921, under all votes and accounts appearing on the public-works appropriations was £3,866,027. If, however, the expenditure under the special accounts (which have their own ways and means) is deducted, the net charge against the Public Works Fund is £3,140,758.

The following is a brief summary of the progress made on each line : — Kaihu Railway Extension. Formation, culverting, and fencing on this section have been practically completed. A certain amount of trimming, however, remains to be done when a ballast-train is available, and a few culverts also require to be built. Platelaying has been completed to Donnelly's Crossing Station yard, but the platelaying in the yard itself will not be possible until the bridge at 23 miles 58 chains has been completed. About 5,000 cubic yards of ballast is still required to complete this work. A goods service has been in operation since September last between Tarawhati and Aranga, and recently it was extended to Donnelly's Crossing. Full advantage has been taken by the settlers of both services. With the exception of the station buildings, this line should be in order for handing over to the New Zealand Railways Department before next winter. North Auckland Main Trunk. Ngapuhi Northwards. Okaihau Section. —The last mile of formation on this section has been completed, but slips have caused much concern. Over 22,000 cubic yards have been remoyed, but further slips and subsidences have since occurred, which will be attended to during the drier weather. Platelaying has been completed to 24 miles 14 chains, 10 miles of fencing have been erected, and a considerable number of culverts have been built. Utakura Quarry has been opened up, a light line laid to it, and a crushing plant erected and is in readiness for operation. It is hoped to put the first lift of ballast on the section between Kaikohe and Okaihau as early as possible, in order to admit of the carriage of passengers and goods. This connection will save at least 25 miles of the present circuitous coach route to Hokianga and Mongonui Counties. Its completion depends upon the Government's ability to finance it. Okoro Section. —Very little work has been done on this section during the year, and operations have now ceased altogether. A short piece of formation was completed, some culverts were built, and a few chains of fencing erected. It is not proposed to do anything further on this line for some time, and, in view of this, substantial provision has this year been made to improve the road from Okaihau to Horeke. Waiotira Northivards. Only a small amount of work has been done on the Waiotira end of this section owing to the removal of men for concentration on the Waiotira Southwards section. On the northern end work has been chiefly confined to tramway-construction from the Wairoa River to the Omana Tunnel. Formation and platelaying are being carried on from the river. The approach cutting to the northern end of the Omana Tunnel has been commenced, and a steam-shovel which is being assembled will shortly commence operations there. It is proposed to lay a tram-line over the tunnel hill to convey the steam-shovel to the southern side after the northern approach has been completed. The reason for operating on this isolated portion is the necessity for making an early start with the Omana Tunnel, which will take a long time to drive, and would, if not started in advance, delay the final connection. Financial considerations may necessitate a modification of this programme. An endeavour will be made during the current year to give effect to the Royal Commission's recommendation regarding the completion of the KirikopuniMangakahia and the Mangakahia-Kaikohe Roads. The result of this work will be that when this section of railway is completed, probably within the next few years, to Kirikopuni on the Wairoa River, the settlers northward of this point will have properly constructed access roads over which produce can be transported to the end of the finished line.

Waiotira Southwards. WaikieJcie Section. —The programme of operations for the year was the concentration of men on the completion of Waikiekie Tunnel, rail connection with, and the early commencement of, the Mareretu Tunnel. The Waikiekie Tunnel was finished about the end of April. The work was one of great difficulty. The ground proved treacherous for the entire length, and particularly heavy and close timbering had to be resorted to. At the northern end a specially designed reinforced-concrete section had to be built before it was possible to timber and drive the rest of the tunnel. Plant and materials for works beyond this tunnel were conveyed over the ridge by means of a wire-rope tramway. This proved a very economical method, and enabled operations to be extended to the Mareretu Tunnel immediately on completion of the work at Waikiekie. Exceptionally good progress has been made, and it is hoped to complete the Mareretu Tunnel by next April. A similar tramway to that in use at Waikiekie has been built over this tunnel hill. The comfort of the men at Mareretu has been provided for by the erection of hut accommodation (120 huts), a boardinghouse, and a recreation-hall, as well as the installation of an efficient water-supply. Bridge - construction over the Mangawai Eiver and Kikowhiti Stream is progressing satisfactorily ; a fair amount of platelaying and ballasting has been done. A small stone-crushing plant is supplying metal for the tunnels. The Department's own sawmill has already cut over a quarter of a million feet of timber for workmen's huts, tunnels, temporary sleepers, &c. Ranganui Northwards. Paparoa Section. —All earthworks were practically completed some time ago. Paparoa Station yard has been extended, and the bank at 92 miles 10 chains raised. Huarau Tunnel was completed about the end of January. This tunnel gave great trouble, the ground pierced being most treacherous. Similar expedients to those used at Waikiekie were necessary. Work, preparatory to platelaying the last 2 chains, was completed in April. The first lift of ballast on this length has been placed, except on the bank at 91 miles 30 chains. Two platelayers' cottages were finally completed, and, with the exception of the Paparoa Station-yard arrangements, little work remains to be done. Mareretu Section. —The permanent survey has been finished, and formation is complete to 93 miles 53 chains (south end of Golden Stairs Tunnel), and in hand as far as 95 miles 24 chains. Platelaying and first lift|of ballast is complete to 93 miles 41 chains. Owing to the slippery nature of the "country between Paparoa Station and Golden Stairs Tunnel, an additional 40,000 cubic yards of material had to be excavated and deposited in the banks, which demonstrated the difficulty of maintaining a train transport service for the delivery of material and supplies to the Golden Stairs Tunnel. A large amount of preliminary work had to be undertaken, such as service roads, drainage, &c, before tunnelling operations could be put in hand. These operations have been completed. Shingle-bins and bath-houses have been built, and water-supply installed at the southern end. The total length of bottom heading driven is 7 chains, and concrete lining has been commenced. At the north end the approach cutting is in hand. The survey of a deviation from Mareretu Station yard to 99 miles is nearly complete. This was necessary owing to the level of the record flood of last year being too near the formation-level. Some eight steam-shovels and nine locomotives are employed on the incomplete section between Portland, on the Whangarei Branch line, and Huarau, on the North Auckland main line, and it is hoped with this plant to effect a temporary rail connection between Auckland and Whangarei before the end of next year. Whangarei Branch. Oakleigh Section.— -With the exception of 30 chains of deviation the whole line to Portland has been laid and covered with the second lift of ballast. A concrete cottage has been erected at the Oakleigh Station, and the bridge at 7 miles 33 chains will be finally completed on the arrival of the steel girders.

Tamaroa Section.-^ Work on this section has been confined chiefly to maintenance (removal of slips), which has been considerable. Ballast has been obtained from Tauraroa Quarry for ballasting, road-metalling, culverting, and tunnel-lining. Waiotira Section— The principal operations have been the removal of slips and the completion of two small deviations. The temporary line will shortly be removed, and a commencement made with permanent platelaying. The unstable nature of the country traversed by this line may be realized when I say that two steam-shovels and two trains have been almost continuously engaged in removing slip-material to keep the line open for works trains. Waipu Branch. Ruakaka Section.—A steam-shovel has recently been commissioned to complete the banks across the mud-flats. The rest of the earthworks have been completed. Waipu Section.— Nearly all the formation over the first 2 miles of this section has been completed. Financial considerations may necessitate a modification of this programme. North Island Main Trunk. Waiuku Branch. Glenbrook Section.— Platelaying has been completed, and the second lift of ballast laid ; cattle-stops built, and station buildings at Glenbrook erected. A goods service was extended to Glenbrook on the 16th May last. Waiuku Section.— Formation has been completed, rails and first lift of ballast have been laid, and the second lift commenced. A concrete overbridge has been built, and a second one begun. _ Station buildings at Pukeoware and Fernleigh, and a Stationmaster's house at Waiuku, havebeen erected, and the rest of the buildings are in hand. It is hoped to hand this line over to the Railway Department for regular working early in the new year. Huntly Branch. Earthwork formation, culvert-building, fencing, and access-road construction are m hand and progressing satisfactorily. In order to provide for a station-yard and mine-siding near the summit of the main divide, the line was relocated and pegged, and plans prepared. Formation is in hand on behalf of the mining company, which will pay for the construction of its own siding. Waikokowai Branch. The permanent survey 8 miles 21 chains in length has been completed. Contracts were prepared for the construction, but owing to the change in the coal situation it was decided not to proceed with the construction at present. East Coast Main Trunk. Waihi Eastwards. Athenree /Secfc'cm.—Practically all earthwork has been completed, except fillings around abutments of bridges, and minor works at the Athenree Station yard. There are still several bridges to erect. Katikati Section. —Earthwork has proceeded at a satisfactory rate, fencing erected, culverts built, and drains opened up over a length of 3 miles. Land-plan surveys completed from 4 miles to 12 miles. Considerable trial surveys were made between 15 miles and 18 miles, and one permanent deviation pegged between 14 miles and 15 miles. While it is hoped that finances will permit of the completion of this line to Katikati before a temporary halt is called, it may be necessary, in order to provide money for more urgent works, to discontinue work temporarily. Tauranga Westwards. Tauranga Section.—A commencement has been made with the erection of three platelayers' cottages at Tauranga Station, and a quarry opened up on the Wairoa River to supply stone for facing banks. Formation is in hand over a length of 4 miles, and 150 chains of fencing has been erected. Land-plan survey completed from 36 miles 32 chains to 39 miles 27 chains. Permanent location has now

D.—l

been decided, and permanent-line survey completed from 35 miles back to 31 miles. No work is proposed on this section at present. Tauranga Eastwards. MatapiM Section— -All the cylinders for the Tauranga Bridge have been completed, and, with the exception of six, are sunk to their proper levels. Much extra, Jabour was entailed during sinking operations on account of the soft nature of the material encountered. This necessitated the manufacture of extra lengths of cylinders. A large amount of work in the preparation of material for this bridge has been done in the Mount Workshops, such as cutting and drilling cleat angles, bracing, transome and cover plates, stiffener-angles, &c. Timber has been laid on which to erect a trial span, and a travelling gantry has been placed in position. Good progress has been made with the formation of the bank between the bridge abutment and Matapihi, and the stone protection work is practically complete to the bridge pier. Mount-Matata. This length of line between the Mount and Matata embraces what are known as the Mount Branch, Te Puke, Paengaroa, Pongakawa, Otamarakau, and Matata Sections, over which an efficient passenger-and-goods service has been maintained throughout the year. In the early part of the year the service was really better than the amount of traffic warranted, which led to its curtailment. The new service has proved sufficient and economical. The whole length has been properly maintained. An extension of the Mount Workshops yard has been made, and platelaying in the yard is in hand. A new mill and car-shop are almost complete, and several buildings have been erected to house additional machinery. The wharf .has been strengthened, and a new water-service to supply the workshops and locomotives has been installed. The output from the Te Puke Quarry was about 10,000 cubic yards of broken metal, about one-half of which was sold to local bodies for road-metalling purposes. Subsidences of banks caused some trouble, but all have been brought up to standard level. Rangitaiki Section.— Permanent rails have been laid over the whole section, although the formation is not finally completed. Five miles of fencing were erected during the year. One permanent reinforced bridge is in hand, and temporary structures over the Tarawera and Eangitaiki Eivers for traffic have been built. The latter has been decked, and now also carries road traffic. This section was opened for goods traffic in September last. Awalteri Section. —Permanent-way has been laid over the full length, also m the siding at Awakeri Station. This section was opened for goods traffic in September, 1920. The policy on this line has been to extend it as rapidly as funds permit, from, the deep waterfront at Mount Maunganui into the fertile plains of the Bay of Plenty district. While it is recognized as very desirable that the Tauranga Section of railway should be connected with the main North Island systems via Waihi, the need for concentration requires that one or other of these desirable works should halt. The construction programme is laid out with this in view, and to dissipate energy in an effort to simultaneously effect a connection would, involve a great loss of money. When the line reaches Taneatua the programme will again be reviewed. Taneatua Section.— Earthwork has been completed on the first 3 miles, and is in hand for another If miles. Service road-bridges have been built and others repaired, and the service road itself extended over the summit cutting. Land-plan survey has been made from 83 miles to 91 miles 20 chains. Permanent pegging of several deviations between 94 miles 40 chains and 97 miles 40 chains completed ; total length, 1 mile 60 chains. The line is now permanently pegged to 97 miles 40 chains. Trial lines have been run from 98 miles to 99 miles 77 chains via upper crossing over Whakatane Eiver. A further trial line through Waimana Gorge has been pegged and levelled from 100 miles 16 chains to 104 miles 66 chains. This work is still in hand. . Whakatane Branch Railway.— -Trial survey was completed to 7 miles 50 chains, while a length of 4 miles 10 chains was permanently pegged.

Gisborne-Wairoa. Ngatapa Section. —Ballasting to the 9f-mile peg lias been completed, several culverts built, and Ngatapa Station yard raised. This raising was necessitated by the general rising of the streams and land in the vicinity as a result of slips on the hills and heavy denudation. A passenger-and-goods service has been maintained throughout the year. Over 400 tons of lime from the Eepongaere Quarry were supplied to the public during the year. Waikura Section. —Fair progress has been made with the formation, as well as culverting, drain-cutting, stream-clearing, willow-planting, platelaying, and ballasting. One steam-shovel is constantly employed removing slips. All except maintenance work, and preliminary work towards tunnels, will be discontinued. Wairoa-Gisborne. Two miles of formation has been practically completed. The approach to the Wairoa Station yard has been partly formed, and road-deviation formed and metalled. The contractor for the erection of the Stationmaster's residence and three platelayers' cottages at Wairoa Station has been hampered by the difficulty of obtaining timber-supplies. Two cottages, however, are now complete. Nothing is proposed to be done here at present. Napier-Wairoa. Eskdale Section. —The first 49 chains of this section are complete except the river gap at 24-chains peg. From 49 chains to 1 mile 69 chains are under contract by the Napier Harbour Board, and are complete except river gap on main and Port lines. The balance to 10 miles 51 chains is ready for trimming and platelaying. One platelayer's cottage in concrete at Eskdale yard is complete, and two others and a Stationmaster's house are in hand. Tutira Section. —Formation is proceeding satisfactorily, stream-diversions and drains are being made where necessary, and culverts built. The service road is being formed and metalled. Permanent-line survey has been completed from 14 miles to 30 miles, as well as various road surveys and trial lines. The programme at present is to complete the line to Eskdale, a distance of about ten miles, before any forward move is made. The Napier-Wairoa-Gisborne Main Road has been extensively improved by the construction of a deviation and the metalling of same on what is known as the Waikare-Mohaka Section, between Napier and Wairoa. Further extensive improvements have also been made between Wairoa and Gisborne over a bad piece of road known as Wharerata Hill. The expenditure on these works amounts to £44,000, and a further £60,810 is allocated for 1921-22. The object in view is to concentrate on the road. The reason for this is that owing to the length of line to be constructed, the character of the country to be traversed (involving as it does a number of very large viaducts), and the present financial situation, it will not be possible to make railway connection between Napier and Gisborne for a very considerable time, and it is felt that it is better to spend a substantial sum in making a through road connection available in all weathers, rather than to proceed slowly with the railway. Waikokopu Branch. Nuhaka Section. —The contractors for the large cutting at Te Uhi abandoned the work. Another contract was let, but the Department had to terminate this owing to the dangerous manner in which the work was being performed. It is now being done by day work under direct supervision of the Department. A steamshovel is utilized, with the result that cost is lower and progress greater. In July, 1920, seventy teams and scoops were engaged between the 3-mile and 9-mile pegs, but the ground becoming too wet they were transferred to the sandhills (9-12 miles), where excellent progress was made. By September all the formation that could be worked between 9| miles and 17 miles had been completed. From September to November little could be done beyond draining and planting marramgrass. Scoop-work was resumed in November, and the whole formation on this section (17 miles) is now almost complete.

Waihohopu Section.—ln August a commencement was made on the high bank beyond the Nuhaka River, but work was only carried on under great difficulties owing to repeated floodings of the river, and in October the men were removed. Labour was difficu t to obtain, and very little work was done till January, when abour became more plentiful. By the end of March all the cuttings were fully manned up to the 21-mile peg. Stratford - Main Trunk. East End. Matiere Section—The enlarging, concrete-lining, and construction of both porta' s of the Okahu Tunnel were completed about December last. Two other tunnels, situated at 6 miles 12 chains and 7 miles 55 chains respectively, were also similarly completed. A commencement was made with the erection of superstructure ot the Ongarue River Bridge at 0 miles 7 chains, the steelwork being fabricated in the contractor s workshop, Auckland. Good progress was made with the construction of two other brdges over the Ohura River. Two overbridges have been built, and two subways are in hand. The approach filling at the Ongarue Bridge is in hand. The approach cuttings to the tunnels at 2 miles 20 chains (Okahu) and 8 miles 40 chains have been completed. Five miles of fencing were erected, and 20 chains of s dmg laid, and it will be possible to start platelaying and ballasting very shortly. ' Ohura Section.— Formation to Matiere Station yard is practically complete. Four of the five tunnels on this section are now complete ; the lining only of the fifth remains to be done. Beyond Tuhua Station yard four bridges are required before platelaying can be completed to Matiere. Of these the concrete piers of one are finished, the foundations are being prepared for the second, and material is being assembled. The foundation piles only for the remaining two have been delivered on the sites. I hope to have the ballast-engine in the Ohura Valley before my next Statement is due. West End. Tahora Section.— Platelaying has been completed. Wing walls were erected at No. 2 tunnel, and the west end of No. 1 was faced, thus completing all tunnels on this section. Private crossings were erected, and drains completed. The stat on buildings at Tahora Station are almost finished. A bi-weekly passenger-and-goods service connecting with New Zealand Railways service at Kohuratahi is in operation. Raehohua Section.— -Very little work has been done on this section. Ine permanent survey is now completed ; permanent platelaying extends to 47 miles 59 chains. Borings for all proposed bridges (railway and road) to the Tangarakau Gorge have been completed, and all earthwork on the Raekohua Settlers Road has been finished. Fleao Section. —The permanent survey was completed to 54 miles, also tor deviation (52 miles 70 chains to 53 miles 52 chains), and plans have been prepared. No forward movement is proposed at present. The impossibility of obtaining the necessary ballast from the Railway Department as originally intended has necessitated the opening-up of a large quarry, with road-crushing plant, near Te Wera. As soon as this is done the completion of the ballasting will be an easy matter. Opunake Branch. Kapuni Section.— Although the shortage of material considerably impeded progress for some months, the Waingongoro concrete bridge has been completed and the west bank of the river protected from erosion by a stone-gabion revetment. The reinforced piles for the Kapuni Bridge have been made. Pier B has been concreted up to top of footing, and the excavation of pier E is in progress. Continued erosion of the western bank of the stream has necessitated stone-gabion facing to protect the west approach embankment. Good progress has been made with the Skeet Road overbridge. Auroa Section.— Work on this section has been confined principally to culvertbuilding and formation. Mangawhero Road Station yard, also Auroa Station yard, have been completed.

Pihama Section. —Preparatory work for future operations has been commenced, workmen's huts have been erected, and a few culverts built. Manaia Section. —Earthwork in the Manaia Station yard has been completed by the contractor. The only unfinished cutting and embankment on this section has been steadily worked and is very nearly completed. As soon as rails and sleepers now on order arrive it will be possible to proceed uninterruptedly with platelaying and ballasting from Te Koti to Manaia. Sufficient formation work towards Opunake to absorb the unemployed will be opened up. Midland. Nelson End. Kaioatiri Section. —Work was commenced on this section in January last with the tunnel at 62 miles 53 chains. The excavation has been carried into the hillside for a distance of 200 ft. An air-compressing plant has been provided for drilling purposes. The Hope River has been diverted, the erection of the bridge at 62 miles 54 chains commenced, and concrete blocks for tunnel-lining are being manufactured. Otira-Bealey. Arthur's Pass Tunnel. — Otira End. — Day - labour principle of employment obtained while some particularly bad ground was being encountered. About the middle of September the ground improved and the co-operative contract system was reverted to ; 21 § chains of lining was completed, and the top-heading finished early in June. Bealey End. —With the exception of about two weeks, work has continued uninterruptedly till July, when the co-operative contract was terminated to allow the workers on the opposite end room to work through. The total advance of lining in this end was 18 chains. The contractors for the electrification have commenced with the erection of the 6,000 cable-racks in the tunnel. The manufacture o: machinery in England was much delayed by the coal strike. It is expected that the cleaning-up of the bottom will be completed in December, 1921, the platelaying in February, 1922, and ballasting in March, 1922. Greymouth - Point Elizabeth. All felling, clearing, stumping, creek-diversions, and culverts have been completed. Of the formation only about 3,600 yards remain unfinished. Only 35 chains of fencing remain to be erected, and about 5 chains of ditches to be cut, to complete these two classes of work. The construction of two temporary bridges is in hand. Rails have been laid to 4 miles 75 chains. In a very short time transport of coal can be undertaken. Waimate Branch Extension. Serpentine Section. —Operations on this section consisted of earthwork only, a half-mile of formation being carried out, which leaves about 55 chains to complete. Difficulty was experienced with the bank between 1 mile 13 chains and 1 mile 22 chains. It is probable a deviation will eventually be necessary to avoid a large slip. No more than maintenance is anticipated this year. X etcher's Section. —Only about 60 chains of formation had been completed when work was temporarily suspended. It will not be possible to resume operations this year. Otago Central. , Cromwell Section. —Seven concrete flood-channels under road and railway were completed. These were found necessary in order to cope with flood-water from cloud-bursts. Concrete or stone-pitched channels were constructed from all existing culverts on this section, and five additional culverts were placed. Six road-bridges were built over the newly constructed flood-channels, and one railwaybridge was erected. The final lift of ballast was laid, and the line finally trimmed throughout. A goods-and-passenger service was maintained until the section was handed over to the New Zealand Railways early in July of this year.

BaLCLUTHA - TUAPEKA MOUTH. A survey party was engaged on this work from March to July, 1921. A trial survey was run from Lovell's Flat to beyond Hillend, via Stony Creek. Certain further information is still required, and is being collected, to enable the various rival routes to be compared. Orepuki-Waiau. Orawia Section. —Formation is in hand over a length of 6 miles. Culverts are now complete to the 54-mile peg, and 124 chains of fencing were erected. The permanent survey has been completed for a distance of about 8 miles to and including Orawia Station. It is doubtful if it will be possible to continue work on this line unless the need of finding work for unemployed continues. Lawrence-Roxburgh. Beaumont Section. —Formation was commenced in April of this year, and extends over about 2 miles. Several culverts have been built and workmen's huts erected. The men employed on this work are chiefly those who were engaged on the completion of Cromwell Section of Otago Central. The survey has been completed for a distance of about 6 miles. Surveys. A flying survey of various routes between Helensville and Shelly Beach, a distance of about 12 miles, was made to ascertain the possibility and probable cost of constructing a branch line to Deepwater, at the southern end of Kaipara Harbour. Additions to Open Lines. The expenditure by the New Zealand Railways Department out of the Public Works Fund under this heading amounted to £421,315. Of this sum £112,248 was expended on providing workshop machinery, additional rolling-stock, and the usual fittings therefor. The balance covered expenditure upon improvements to workshops, engine-depots, station facilities, water-services; additional dwellings; signal, tablet, and telephone installations; interlocking; gasworks extension; and purchase of land. Railways Improvement Authorization Act, 1914. The expenditure under the Railways Improvement Authorization Act, 1914, amounted to £63,078, for grade easements, additions to workshops, formation of new lines; signalling, interlocking, and safety appliances; and extension of terminal facilities at Auckland, Wellington, and Christchurch. PUBLIC BUILDINGS. General. Government House, Wellington. —Extensive alterations were effected to this building, and additional official accommodation provided for His Excellency the Governor-General and staff by the subdivision of a number of rooms. A new porch was erected at the entrance, an additional strong-room built, and the main drive widened. Parliament Buildings (New Buildings). — The external marble work was practically completed during the year, only the balustrade in front of the loggia remaining to be done. The following rooms were completed and furnished during the j ear : The Speakers' suites of both Houses ; three suites for Ministers ; sitting-rooms and writing-rooms for members of the Legislative Council and House of Representatives ; Government and Opposition Whips' rooms ; Leader of Opposition's room ; Clerk and Assistant Clerks' rooms, Legislative Council; Bill Officer's room for each of two Houses ; and waiting-rooms for Legislative Council. The plastering and internal finishing of the rooms were completed, with the following exceptions : Three suites of Ministers' rooms on the ground floor; the front entrance hall on all floors, and main staircase, and the waiting, messengers', and store rooms in connection with and adjoining thereto; also the three large social rooms for members on the second or top floor. The Legislative Council chamber was entirely completed.

Departmental. Auckland Law Court Buildings. —Alterations have been carried out to the first floor to accommodate tenants transferred from the third floor. Christchurch Customs Offices. —The erection of this building in Carlyle Street has been commenced, and will shortly be completed. A contract has been let and a commencement made with the erection of the Wanganui Native Land Court Building; and the Greymouth Explosives Magazine has been completed. Courthouses. New Courthouses are urgently required in several places, but in view of the present financial conditions only urgent repairs and necessary maintenance work of existing buildings have been carried out. Prisons. Progress in building-construction during the earlier part of the year was delayed to a considerable extent through shortage of timber and cement. Subsequently, when materials were more easily obtainable, a curtailment of expenditure hampered the building programme. At Auckland the expansion of quarrying operations and the erection of staff cottages were the principal works carried oiit. The installation of pneumatic drills, &c, has enabled the output of crushed metal to be greatly increased. Additional crushing-plant is being obtained, and bins and improved loading-facilities are to be installed. The erection of additional cottages and quarters for single officers was proceeded with at Waikeria. Similar work was carried out at Wi Tako (Trentham) Prison, where cottages removed from the Wellington Prison Reserve were re-erected, and a new residence for the officer in charge completed. The manufacture of bricks on the Mount Cook site having been discontinued some time ago, advantage has been taken of the presence of extensive clay-deposits on the Wi Tako Reserve to establish the industry there. The work of excavating and preparing the site for the brickyards, as well as the erection of plant, with the necessary buildings to house same, has been completed. A temporary kiln has been constructed in which a large proportion of the bricks required for the permanent kiln have been burnt. It is expected that this kiln will be completed and in working-order by the end of the year. Roadmaking between Waimarino and Tokaanu ceased during the year, and the prison camp was removed to Erua, where a start has been made with the reconstruction of the OhakuneWaimarino Road —a section of the central main arterial road. At Templeton the construction of the new institutional buildings and officers' residences has been carried on, and a large supply of concrete blocks and tiles has been manufactured for use in this work, as well as for the erection of workers' homes under the Labour Department's housing scheme. The works carried out at Invercargill Borstal Institution have again been on a comprehensive scale, and in the development of the reclaimed area much work has been done in roadmaking and drainage. A massive embankment, a mile and a quarter in length, enclosing an area of 270 acres of estuary land required for a rifle range, has been completed. This area is being used for agricultural and pastoral purposes also. The erection of cottages and the new kitchen and infirmary block at the Borstal Institution has also proceeded satisfactorily. Police-stations. Owing to the high cost of erecting new buildings, expenditure in this respect was confined to such urgent works as could not be postponed. New police-stations were erected at Dannevirke and Hokitika, a residence for the Senior Sergeant at Palmerston North, a lock-up at Te Araroa, and a new stable at Eketahuna. In many cases where the Department's tenancy of rented premises was terminated, or where departmental buildings had become beyond repair and unfit for habitation, suitable properties were purchased when offered at a reasonable price. As compared with the estimated cost of erecting new buildings, this was found to be the more economical means of providing the necessary accommodation without undue delay. Such properties were purchased for use as police-stations at Rongotea, Woodhaugh, Lower Riccarton, Levin, Portobello, Port Chalmers, Seatoun, Ashhurst, Millerton, Belfast, Upper Hutt, Otira, Palmerston North (Cuba Street), Fortrose, Wanganui East, Green Island, St. Kilda, Ravens-

D.-l

XIV

bourne, St. John's (Wanganui), and Brooklyn (Wellington). Residences for senior officers of the Police Force were also purchased at the following places, where the difficulty of obtaining rented houses rendered it necessary for the Department to provide accommodation : Whangarei (Inspector's residence), Greymouth (Inspector's residence), Hamilton (sergeant's and detective's residences), Wellington (Chief Detective's residence), Invercargill (residences for senior sergeant, sergeant, and detective). Post and Telegraph Buildings. Owing to the difficulty experienced in procuring labour and material, and latterly to the financial stringency which demanded that only urgent and essential work should be undertaken, the expenditure during the year was not very great. The result has been that several important works involving considerable expenditure have had to be deferred. This is particularly unfortunate, as during the period of the war many new Post Office buildings and improvements in existing buildings could not be proceeded with, and at the termination of the war the Department, so far as its building programme was concerned, was practically several years in arrear. A big effort was made to overtake deferred work, but the Department was immediately faced with the problems of shortage of material and labour. Time after time no tenders were received for the erection of buildings required urgently. When conditions regarding material and labour improved, a financial position arose which made it necessary to curtail the programme already planned. It is realized that when conditions improve a very active building programme will be necessary to bring the facilities of the Department up to the pre-war standard. During the year Post Office buildings were erected or their erection completed at Crookston, Glen Massey, Kelburn (for automatic-telephone exchange), Ormondville, Owhango, St. John's (Postmaster's residence), and Sutton ; while important alterations were made to the Post Office buildings at Auckland, Dunedin, Invercargill, Rangiora, Rawene ; Ruatorea, Timaru, and Wairoa. The acute shortage in housing during the year made it difficult for officers in some places to obtain accommodation, and rendered necessary the purchase by Government of residences for Postmasters and other officers at the following places : Balclutha, Blenheim (two), Coromandel, Darfield, Eltham, Frankton Junction Railway, Greymouth, Hamilton (four), Matamata, Ohura, Pahiatua, Palmerston North, Stratford, Te Araroa, Timaru (three), Tolaga Bay, Waitara, and Waverley (two). Agriculture. At Ruakura Experimental Farm a building has been erected to house the electric-light plant. Additional quarters and larger kitchen accommodation have been provided on account of the extra number of returned soldiers. A store, transformer-house, and two cottages are in course of erection. The scheme of field drainage was deferred for the time being, so also was the erection of a modern milking-shed, at the Central Development Farm at Weraroa. The completion of the electrical installation at Ruakura (which has already been connected with Horahora power scheme) and the extension of the waterservice, as well as the erection of a store at Motuihi, are amongst the proposals for the current year. Mental Hospitals. In addition to ordinary maintenance work, good progress has been made with the additions to the Women's Auxiliary building at Auckland. This new unit will accommodate about eighty patients, and is so constructed as to admit of their further classification. At Tokanui the Male Admission Block is well advanced and a large workshop is almost complete. Material for the Female Admission Block, the foundations of which are finished, is on the site. The Reception-house at Nelson should be completed within the current year. The poultry-farm has been remodelled, and the necessary buildings erected. The residence for the head attendant at Christchurch is nearing completion; as also are general additions and alterations at Hornby. A two-story addition, which will increase the day-room space of two wards in the main building, is well advanced. Additional accommodation for sixty female patients at Seacliff is nearing completion.

Hospital and Charitable Institutions. The principal work carried out under this heading during the year was providing more adequate accommodation and equipment at the quarantine stations at Auckland and Wellington ; the establishment of a new St. Helens Hospital at Wanganui; and improving the accommodation at other similar institutions throughout the Dominion. Some expenditure will be required during the current year for the military hospitals that have been taken over from the Defence Department to adequately equip them, for the purposes for which they are intended, and to complete the quarantine stations which were commenced during the previous year but which were not entirely completed. Education. During the past financial year the expenditure out of loan-moneys on Education buildings was easily a record. During the war the necessity for economy led to the restriction of capital expenditure wherever possible, and consequently when peace came large arrears of work had to be overtaken. During the year 1920-21 the total expenditure on Education buildings was £459,292 —£244,721 from the Public Works Fund and £214,571 from the Education Purposes Loan. Of this total £279,659 was for new primary-school buildings, £67,216 for technical schools, £43,910 for secondary schools, and £37,243 for the University colleges. At the end of the year the grants promised but not paid amounted to £825,661, as against £560,051 for the previous year. The total new authorities issued during the year amounted to no less a sum than £724,902. Though much has thus been done to meet the pressing needs for more and more school accommodation, unfortunately, owing to the very high cost of building and to the large arrears referred to above, the provision made falls far short of the essential requirements. The present financial stringency has again necessitated a restriction of the expenditure, but the Government is fully aware of the needs of the country, and is only awaiting more favourable financial conditions to revert to its progressive building policy. In some districts where additional accommodation is urgent the residents have come to the assistance of the Government by subscribing to the Education Purposes Loan the sums required to provide. the additional school buildings, and in this way buildings are being undertaken that otherwise would have been postponed for a considerable time. Lighthouses. The erection of the automatic fog-signal on Tiritiri Island was completed, and the fog-signal handed over to the Auckland Harbour Board. The necessary apparatus for automatic lights on the Ninepins Rock, Gable-end Foreland, and Mercury Island Passage arrived during the year. The tower for the Ninepins light has been received, and the erection of the light-tower is now in hand. During the year the Wigham light, in Helensville Eiver, Kaipara Harbour, has been replaced by an automatic acetone light. As East Cape Island has become dangerous as a site for the lighthouse, a new site on the mainland has been decided upon, and the transfer of the lighthouse from the island to the mainland will be undertaken this year. HARBOUR-WORKS. During the year very little has been done in the nature of works in the harbours under the control of the Government. All the biioys and beacons in the harbours under the control of the Department have, however, been regularly overhauled, cleaned, and painted, and where necessary new moorings have been put down. TOURIST AND HEALTH RESORTS. The total expenditure incurred during the year was £19,041, as against £6,194 for the previous year. The greater part of this expenditure was incurred at Rotorua, mainly on the completion of the work of replacing the wooden water-mains by cast-iron ones. This work, which has been completed so far as the town is con-

D.—l

cerned, absorbed £10,000. The electrical works at Eotorua cost £2,311 ; and the bringing-in of a further supply of hot mineral water to augment that from the Rachel Spring, £2,202. This last item will provide a practically unlimited supply for many years to come. ROAD CONSTRUCTION AND MAINTENANCE. The sum provided on the estimates last year for road and bridge construction and maintenance was greater than that of any previous year since the inauguration of the public-works policy. The expenditure also constituted a record. The efforts of the Department have been directed mainly in providing primary access to lands already in occupation, but the improvement, widening, and metalling of existing access roads, and the construction and renewal of bridges, have not been neglected. The greater part of the work has been undertaken by my own staff, but subsidized works, such as metalling, renewal of bridges, &c, were in most cases entrusted to the local bodies concerned. A certain amount of modern roadmaking plant has been purchased and used with successful results. The use of motor-lorries has cheapened the cost of haulage of metal, steam-shovels have been installed where the magnitude of the work warranted, and oil-driven road-rollers are being used in connection with metalling operations. In the prosecution of the various activities connected with roads and bridges it is desired to utilize to the utmost all plant and machinery suitable for that purpose, whether the property of the Department or of the local authorities, so that all efforts may be co-ordinated towards the adoption of methods that would contribute towards efficiency, economy, and expedition in the carrying-out of works. It has been recognized that where there are at present no railway facilities, nor any likely to be in the early future, it is reasonable to provide suitable roads so as to compensate as far as possible for such disabilities. In accordance with this principle particular attention has been directed to the energetic prosecution of work in the formation, metalling, and bridging of such important road connections as those between Napier and Gisborne, and between Te Kuiti and Waitara. It is proposed that in future the appropriations for roads and bridges be based on an automatic system whereby those districts that are backward in roading and in development shall receive a greater proportion of the amounts available than will other districts that are already well roaded and well developed. The basis for adjustment will include such factors as mileage of roads unopened, areas of Crown and Native land undeveloped, areas of districts, populations, productivity, loans, and mileage of roads still requiring improvement. Efforts have been made and will be perfected whereby local authorities will be brought into closer touch with local public-works representatives. For instance, district and resident engineers will nave the advantage of discussing proposed allocations direct with local authorities. This, it is hoped, will bring about better understanding and combined purpose and effort. TELEGRAPH EXTENSION. During the year 46 miles of telegraph and inter-urban telephone pole-line, carrying 615 miles of wire, were erected. In connection with telephone-exchange subscribers' lines an additional 330 miles of pole-line, carrying 4,263 miles of open aerial wire, and 41 miles of cable containing 11,446 miles of wire, were made available. The coin-in-the-slot telephone machines were increased by twenty-four during the year ; telephone exchanges were increased by five, whilst twenty-five others are in various stages of completion. The number of new subscribers joined to telephone exchanges during the past year was 8,785, and this increase necessitated additional switchboard accommodation at fifty-five exchanges. The installation of automatic exchanges is proceeding at Auckland, Palmerston North, Wanganui, Kelburn (Wellington), and Oamaru. Owing to the comparative shortage of material, the development of the automatic telephone-system has been severely handicapped, but every effort is being made to provide for all requirements as speedily as conditions will permit.

D.—l

XVII

The installation of automatic printing-telegraphs has been delayed by the nonarrival of the greater part of the apparatus ; but this is now coming to hand, and it is expected that an installation of this up-to-date system will be made at an early date. The Chief Telegraph Engineer has returned from a visit abroad ; and, as a result of his investigations into the telegraph and telephone systems, also methods and rates of operation, in other parts of the world, increased efficiency combined with economies in both telephone and telegraph services may be expected. CONTINGENT DEFENCE. Owing to the exercise of the strictest economy in the Defence Department, only £8,700 of the £15,000 appropriated last year was expended on urgent and necessary works. The formation of a rifle range at Invercargill has been accomplished by the reclamation of an area of 270 acres. This land will be brought under cultivation by the Prisons Department, in connection with the Borstal Institution, in addition to providing a rifle range for defence purposes. The reduction in administrative groups from twenty-one to twelve, contingent upon the reorganization of the New Zealand Military Forces, will have the effect of reducing the number of full-sized ranges to be maintained. As a consequence of this policy no further expenditure in the direction of acquisition of land for rifle ranges will be necessary. The accommodation for military equipment and stores, and magazines for ammunition, is inadequate, while the present system of housing all reserve military stores at Wellington and Trentham is unsatisfactory and unsuited for rapid mobilization. Consideration is therefore being given to the acquisition of mobilization stores and magazines in each of the three military commands (Northern, Central, and Southern), in order that the troops in each command will be self-contained in regard to provision of their requirements on mobilization. It is proposed to dismantle huts at Featherston and to re-erect them at various small drill centres for use as drill-halls, stores, and miniature ranges. It is also intended to convert a few of these hutments into quarters for the married permanent personnel in localities where ordinary housing facilities are not available. LANDS IMPROVEMENT. The roading of improved-farm settlements has been completed. A small sum is, however, being provided in the estimates this year to meet special cases as they may arise, such as the formation of deviations of roads, &c. LANDS, MISCELLANEOUS. The sum of £2,537 was expended on the construction of roads in the Hauraki pastoral area. The work was somewhat delayed owing to the difficulty of obtaining supplies. The principal works of formation, widening, and reconditioning of roads in hand are the Tapu-Gumtown Koad, Kaueranga-Tairua Road, Mill Creek Road, and the widening of the Port Charles to Jackson Track. In consequence of the roadworks an early settlement of discharged soldiers is expected along the Tairua Eoad, and the Tapu-Gumtown works will afford access to a large area of reasonably good country in the Tapu district. LAND FOR SETTLEMENTS ACCOUNT. Roads to open up Grown Lands. —A sum of £252,800 was appropriated for this purpose, but labour difficulties and shortage of material retarded progress, and a comparatively small expenditure of £28,920 was incurred. A more vigorous policy of settlement is being pursued, and the construction of roads opening up the various blocks of land for settlement is being carried out as expeditiously as possible, and works involving an expenditure of £154,692 are at present in hand.

DEVELOPMENT OF MINING. Of the £2,153 expended under this head last year the major portion was in connection with the purchase of drills for prospecting purposes. IRRIGATION AND WATER-SUPPLY. Ida Valley Scheme. Syndicate Race. —This has been extended nearly 2 miles and is completed, with the exception of a few culverts, to 11 miles 76 chains. German Hill Race. —The work of completing this race, which had been previously partially constructed, was commenced in the spring of last year, and is still in progress. A deviation to avoid a flume at Kirk's Creek has been made. The only works now remaining to be done to link up this section are a flume at Moa Creek and a weir at Poolburn. Drainage. —The scheme for drainage of portion of the valley was extended by clearing'2o chains of Moa Creek, and the erection of one private-crossing bridge and one public-road bridge. Irrigation. —About 40 miles of races were maintained for the supply of water during the season 1920-21. Over 4,400 acres were irrigated. Galloway Flat. Dip Creek Weir. —A concrete diverting-weir and measuring-device at the intake were completed. Main Race. —The main race, 7| miles in length, together with necessary flumes and gauge-boxes, has been completed with the exception of a few minor details. Water was used from it towards the end of the irrigation season. , Irrigation. —The previously constructed race which supplies water on the north side of the railway was cleaned out. A limited quantity of water was supplied by temporary means. About 160 acres were irrigated. Olrig Terrace Scheme. No construction was undertaken during the year. About 75 acres were irrigated, the water being supplied through an old existing race. Manuherikia Scheme. IntaJce Tunnel. —The remaining 1-22 chains of tunnel was driven. Lining, where necessary, over a distance of 4j chains, is completed. Of the remainder about 4 chains require lining. Excavation for an inlet from the Manuherikia Eiver to the tunnel is in progress and about three-fourths complete. Excavation for the gravel-trap at tunnel-outlet is ready for concreting. Main Race. —Excavation of the main race has been extended to its terminus. Three deviations to avoid flumes have been made. Chatto Greek Siphon.—A double line of 1,800 ft. of piping (22 in. to 26 in. diameter) is on the site ready for setting when the necessary Australian hardwood arrives. Ardgour Settlement Scheme. This is a new scheme, commenced in June last, and when completed will supply water for the irrigation of about 2,000 acres of good settled land. Earnscleugh Scheme. Water rights and races from the Fraser Eiver have been purchased from the Sandy Point Gold-mining Company, and plans and estimates for a comprehensive scheme to irrigate Earnscleugh Plat with water therefrom have been completed. Water will be available for irrigators during the coming season. After personally inspecting the arid areas proposed to be irrigated and those already irrigated I am satisfied that in irrigation will be found the salvation of Central Otago. Really wonderful results have already been achieved : 1,700 sheep carried on 300 acres, not all irrigated, is an example, while £20 clear per acre is being taken from lucerne after allowing for water rates, rent, labour, &c. While the area irrigated is still only a small proportion of that commanded, the work is

D.—l

steadily increasing, and, as labour becomes easier to obtain, still will it more rapidly increase. Already the work is self-supporting, though interest is not yet covered. It is recognized that irrigation farming, like bringing into profit bush and swamp areas, involves expense and very heavy work on the landowners. A man with a fair area of land cannot bring the whole of it into profit immediately the water is turned on, and in order to meet this difficulty and give irrigators time to bring their farms into full bearing arrangements have been made to charge for water on a graduated scale, commencing at a very low figure and increasing annually, so that at the end of five years (by which time the land should be fully developed) the full charge for water will have been reached. As this concession in the early stages will result in a certain amount of loss, this loss has been added to the capital invested for the purpose of computing the annual charges, so that eventually there will be no loss to the State. WAIHOU AND OHINEMUEI EIVERS IMPROVEMENT ACCOUNT. Upper Waihou. —Ten chains of clearing have been done on each bank, and on the left bank Wiggin's Gap stop-bank, 27 chains in length, has been completed. 215 chains of clearing have been finished on the left bank of Tirohia-Ngararihi Section, and the river snagged for a similar distance. The final stop-bank has been completed for a distance of 81 chains. 105,000 cubic yards of sand were pumped by the dredge, and the preliminary stop-bank completed for a length of 14 chains. On the opposite or right bank 358 chains of clearing were done, and lj miles of preliminary stop-bank finished. A further section, 2 miles long, is now in hand. Lower Waihou. —On the Ngahina-Hikuraia Section clearing over a length of 3j miles on the left bank and 3| miles on the right has been finished. A drag-line excavator has done excellent work under unfavourable conditions. On the left bank the preliminary stop-bank, 2 miles in length, is complete, except temporary gaps left for drainage purposes. A further miles is in hand. On the right bank, with the aid of tractors, ploughs, and scoops, the preliminary bank has been completed to 2 miles 60 chains, and a further mile is now in hand. Komata Creek. —A second drag-line excavator commenced work in April last, and 10 chains of creek-diversion have been excavated, and the material deposited in the preliminary stop-bank. Clearing has been completed for a length of 20 chains. Ohinemuri. —Willows have been ring-barked over a length of 62 chains, and the stop-bank brought up to preliminary level. TiroJiia-Ttotohohu. —Over 2 miles of drains have been excavated to final depth and width by means of a dipper dredge. The output for this machine was over 37,000 cubic yards for the year. The question of allocation of cost of this work has for some years been exercising the minds of those responsible for payment, and it was felt by all parties that the allocation made by the 1910 Act did not now represent the position. A Royal Commission was set up on which the mining and agricultural interests were represented, and their report will shortly be laid on the table of the House. Whether or not the Government will be able to carry out in full the recommendations of the Commission has not yet been definitely decided, but meanwhile work will proceed as at present. HYDEO-ELECTRIC POWER. Lake Coleridge Supply. The financial result of the operation of the Lake Coleridge system for the year ending 31st March, 1921, has again been very satisfactory, and, after paying all operating, interest, and depreciation funds, has allowed the deficit on the first four years' operation to be still further reduced. The revenue for the year was £51,373, and the expenses were — £ Working-expenses .. .. .. .. .. 21,341 Interest .. .. .. .. .. ..18,639 Depreciation .. . . . . .. 7,946 £47,926 giving a profit of £3,447, which will be used in the reduction of the accumulated deficit on the first four years' operation.

There are, of course, in addition to the direct profit shown above, indirect benefits conferred on the district by having this source of power available, which have so increased the demand for power-supply that the plant has been run overloaded continuously throughout the year, and numbers of prospective consumers have had to be refused connections until extra plant can be installed. During the year the load on the plant reached 7,412 kilowatts, although the normal full-load rating of the machines is only 6,000 kilowatts. The fifth unit (4,000 horse-power) has been installed during the year, and the pipe-line to supply this was expected to be completed by October of this year. It is hoped that if this machine gives satisfactory trial runs it will be able to take up a share of the load before the end of the year. A further unit of the same size has also been ordered, and should be completed and in service during 1922. The level of the lake had been falling gradually as the load has exceeded 6,000 kilowatts, that has always been considered the limit of power available from the Lake-stream itself, without the addition of water from the Harper, Acheron, or Wilberforce Eivers. During the year a channel was excavated from the Harper River bed into the lake, and a temporary diversion of the river made into this channel. This has proved very successful, and the lake-level has risen consistently ever since. It is proposed during the coming summer to complete a permanent diversion of the river into this channel, which will enable the Coleridge station to be duplicated and brought up to a. capacity of at least 36,000 horse-power. It is anticipated that this will meet the demands of both North and South Canterbury for some years. A start has been made with the erection of a transmission-line to give supply to South Canterbury, and it is anticipated that a limited amount of power can be supplied over this by the end of 1922, and a complete supply when the duplication of power-house, for which plans are now being prepared, is completed. Horahora Power-station. This power-station, which was taken over from the Waihi Company and operated on behalf of the Department for the concluding five months of the preceding year, has been operated by the Department for the past year. As in early years of the Coleridge undertaking, the first year of operation of this plant does not show a profit after allowing for all charges. It is satisfactory, however, that the whole of the operating-expenses have been paid, together with a substantial sum towards interest and depreciation even at this early stage of operation. The revenue for the year ending 31st March, 1921, was £14,805, and the expenses were as follows : — £ Operation .. .. .. .. .. 6,452 Interest .. .. .. .. .. ..10,675 Depreciation .. .. .. .. .. 3,960 £21,087 leaving a deficit of £6,282 on the year's operation. Next year's revenue should show a very substantial increase, as it was only towards the end of the financial year just closed that any consumers other than the Waihi Gold-mining Company were connected up. Since the close of the financial year supply has been given to the Hamilton Borough Council, and to the Thames Valley, Te Awamutu, Central, and Cambridge Power Boards, which will very considerably increase next year's revenue. A contract has been made with the Grand Junction Company to take a supply of power from our system so long as we have it to spare, and when our supply becomes limited, or in the event of a failure of supply, we can utilize the company's steam plant up to a capacity of 2,000 kilowatts to supply power back into our system. Similar contracts on a smaller scale have been made, and others are being negotiated, with some of the dairy companies in the district which already have efficient steam plants. The maximum load on the station during the year was 3,600 kilowatts, but it is anticipated that by the end of the present year the load will have reached very nearly the limit of the present plant, 6,000 kilowatts. Tenders have been invited for two additional units of 2,000 kilowatts, which it is proposed to add to the present station, and preparations will be made for installing this plant as soon as it can be delivered. The work of erecting the transmission-lines necessary to give supply to the different Power Boards has been pushed on vigorously during the year, and all the Boards are now in a position to take power at one or more points.

Electkic-power Boards. A large amount of work in connection with the formation of Power Boards has been done during the year, although the total number finally constituted has only increased by four. Quite a number of other districts have, however, taken steps to form Power Boards and have circulated petitions, so that this number will be considerably increased during the next twelve months. Nine of the Power Boards at present constituted have already laid out reticulation systems and submitted loan proposals to the ratepayers. The loan proposals authorized amount to £2,950,000, equivalent to £21-6 per head of population concerned and to 67 per cent, of the unimproved rateable value of the districts included. It is becoming generally recognized throughout the country that the distribution of power by means of Boards specially set up for the purpose will result in the actual consumer obtaining his power-supply on the best possible terms. Whilst it is recognized that the system adopted in Christchurch in connection with the Lake Coleridge scheme, under which supply is given by the Department to individual local authorities, has been very highly successful, and was necessary while the electric-supply business was growing and on its trial, it is now felt that better results can be obtained by deputing the whole of the business of distribution and supply in a district to one body whose special business it will be to see that the power is mad,e available to all on the very best terms possible. With the policy of the Department supplying in bulk to a number of smaller local authorities it has been found that in many cases both the Department and the local authorities have to carry staffs and equipment to deal with this branch of the business, and that there is apt to be overlapping and. duplication. It has also been felt that some of the local distributing authorities are too small, and that in consequence they have been unable to provide the special staff required to efficiently manage their electric-supply business, or, alternatively, that the staff and overhead expenses bear an excessive relation to power distributed. My natural inclination is to let local authorities manage their own affairs ; but after a very careful investigation of the proposals put forward by my expert officers, which are designed at every point to work in with the development of the most economical schemes in the interest of the country as a whole, and pay due regard to community of interest, I am convinced that it is necessary for the Government to insist on the formation of Electric-power Boards, in conformity with the scheme prepared by the Department, and not those dictated by immediate local interest vitiated to a considerable extent by existing licenses. The case is definitely one where, for the eventual good of the whole community, town and country must assist one another to finance the undertaking and to secure what is the secret of financial success in any electrical undertaking —namely, diversity of load, and distribution, over as wide a load as possible of the costs of operating and management. In the reports attached to the Public Works Statement of 1920 the Department laid down as a basis what it was considered should be the districts to be administered, in the matter of distribution of electric supply, by the various electric-power Boards constituted or to be constituted. It is essential, for the final and best success of the Power Board's scheme, that the primary matter of development of electric power, and the secondary matter of its distribution, should be considered and dealt with in its initial stages not from the point of view of immediate or local circumstances, but from the point of view of ensuring that final development and organization will be on the lines to secure to the Dominion as a whole the most economical and successful means of development of power and its distribution. The great objective is the development and distribution of electric power to the consumers at the cheapest possible rate. The only possible way to achieve that end is to plan from the beginning the eventual scheme of development, and to eliminate the minor considerations and influences dictated by circumstances of temporary expedient and local influence. Prior to the coming into operation of the Electric-power Boards Act, in the matter of development of electric power and its reticulation and supply to the people (apart, in the matter of development, from the Coleridge scheme, which was largely educational), the organization of existing local authorities had to be utilized. An existing local authority, other than an electric-power Board, has many interests, only one of which may be the distribution of electric power. Because hydro-electric power and light, unless in most exceptional circumstances, are so much cheaper than any other form of development, the public pays, without cavil, the price demanded by the distributing authority. The perfectly natural tendency of such a distributing local authority is to make all the profit it can out of such a

:d.—l

XXII

service ; and because the charge on the individual consumer is something less than the price at which he could obtain a similar service from elsewhere, he pays without demur. The result is that the consumer is paying|more than he should, and the profit is being utilized in reduction of the cost to ratepayers of other works and services which should be financed on their own ways and means. This, it must be understood, is a general statement having particular reference to hydro-electrically-developed power distributed by local authorities other than Power Boards. An Electric-power Board, having only one interest, has no object other than to supply the consumers at the cheapest possible rate, and is therefore to be infinitely preferred as a distributing medium. It is to be regretted that some local authorities, particularly certain municipalities who hold licenses to distribute power developed from existing plants, are showing a tendency to stand out of Power Board schemes, hoping, no doubt,, to carry on with their own power development (meantime making what profit they can out of the sale of power) and later on to take power in bulk from any scheme developed by the Government, or to bargain with a Power Board developing its own power, and continue, in the event of a satisfactory bargain with either party, making a considerable profit out of the retailing of power and light. This is not in the interest of the consumer. Other Local Electric-supply Authorities. Several of the existing local electric-supply authorities are making arrangements to extend their plants and have works under construction, but, following on the difficulty of obtaining supplies during the war period, they now find the existing financial stringency hindering them considerably in some of the works contemplated. Seven additional licenses to erect plants have been issued, mainly to isolated districts which cannot hope to be connected to the general Government supply for some time, but no new plants have been put into operation during the year. Care is taken in all these cases to see that the works and plant are being designed on lines which will allow of these undertakings working in with the Government supply when available. Government Hydro-electric Proposals. The Government has adopted a general scheme of power-supply to the North Island as laid down in a report (1918) by Mr. Parry, previously Chief Electrical Engineer, which provided for three main generating-stations, at Mangahao (24,000 h.p.), Arapuni (96,000 h.p., capable of extension to 162,000 h.p.), and Waikaremoana (40,000 h.p., capable of extension to 136.000 h.p.). This scheme was adopted after consideration of many alternatives of a general supply from a number of smaller stations, or of an initial supply from one large central generatingstation, as being the one best suited to fill the conditions which are likely to arise within the next few years ; without unduly loading the cost of initial development, or without causing the prospect of having to incur further heavy liabilities at a later date when the supply from smaller sources should become overtaxed. The cost of operation and organization for delivery of power to Power Boards are practically the same for a 50,000 h.p. delivery as they are for a 5,000 h.p. delivery ; and let it be borne in mind that in actual working these are the costs that count and for which the consumer pays. I that an attempt is now being made, by parties not wholly disinterested, to induce the general public to believe that it is better to go ahead with a large number of small schemes than to await the development of the main Government schemes. The measure of development of Government schemes must be dictated by the ability of the country to finance them. The Government's margin of credit and security is immeasurably greater than that of any local effort. If the public is convinced by the agitation to which I have referred, then it must believe that fifty power schemes can be financed, constructed, organized, and run, and supply the same amount of power, as five power schemes developing an equivalent amount of power. Such a conclusion is, to my mind, unsound, and I feel assured that the public will realize it before they enter into commitments for which they will pay for all time, or, alternatively, have to scrap their plants and cut the loss incurred by impatience.

Provision for the raising of the necessary loans to carry out the three main schemes above was made in the Electric-power Works Loan Act, 1919, and in the Finance Act of 1920, but owing to the difficulty of obtaining labour or material at a reasonable cost during the period immediately following the war, and owing to the high rates of interest now ruling, it has been decided as inadvisable to proceed with the active construction of the whole of these works at the present time. It may be unfortunate that I have to preach this doctrine at a time when financial stringency compels the Government, and should, but apparently does not, similarly compel local organizations, to hasten slowly with a view to securing development at lowest possible capital cost. If local organizations would calculate with the same exactitude that my Department has done the eventual cost to the consumer of the various schemes which they propose to carry out at existing costs as against the cost of bigger schemes taken in hand and pushed through in the minimum time, once the money required to carry them out is definitely available, they would realize the wisdom of the Department's view. It must be remembered that in large electric-power works, of the total cost of power as delivered to our consumers from 70 to 80 per cent, is due to capital charges, interest, depreciation, and sinking funds. It is essential, therefore, that the works, when undertaken, must be carried out in the most economical manner that is consistent with good work and proper provision for extensions and for the future, if these capital charges are to be kept down, and power to be sold at the lowest possible rate. To reduce the interest charges during construction also it is essential that, once started, the works must be carried along on businesslike lines, so that they may reach a revenue-producing stage as early as possible. When it is realized that a reduction of 1 per cent, in the rate of interest payable on the loan-moneys means that the cost of power supplied can be reduced at least 11 per cent., apart from any reduction due to the general reduction in cost of material that would naturally follow a reduction in interest, it is evident that we should very carefully consider embarking on any undertaking involving large capital expenditure if there is any early prospect of a drop in the money-market, unless by delay we are seriously retarding the industries of the country. Though the full programme of development which it was hoped to carry out when the scheme outlined above was adopted has not been started., yet the Department's activities in hydro-electric development have been greater than in any other year in the history of the Dominion. The expenditure on extensions to existing schemes and in the development of new ones amounted to £325,234. To carry on the schemes to which the Department is already committed and on which work has commenced means the expenditure of the following sums during the next few years : —

which sums total over three millions and a quarter commitments for development , " to end of 1923-24, or total to 1929 of £4,715,500. Were the whole scheme gone on with these expenditures would grow considerably, and the country would be faced with the following expenditure to complete these in the time that is desirable if the work is to be done in the most economical manner : —

With these figures in mind, and considering the arguments above in regard to costs in relation to interest rates, it is evident that the best results to the country will be obtained by holding back as much of this expenditure as is possible at the present time; and then, when conditions are more favourable, embarking upon a concentrated and vigorous scheme of construction, on carefully considered plans, that will give the country a supply of electricity that will not be loaded for years to come with high charges consequent on the abnormal costs of construction at the present time. This is applicable not only in the case of large generating-stations proposed by the Government, but also to various alternative local schemes proposed at various times, which in the aggregate would amount to an even larger expenditure than is involved in the Government proposals, and which if rushed into now would only load the country with unduly expensive power for years to come. Construction work at the Mangahao scheme, which is to supply power to the Wellington District, has been actively pushed on during the year. The necessary roadworks have been completed, and considerable lengths of each of the two tunnels excavated. It is hoped during the coining summer to start active construction work on the two dams. Some difficulties were experienced in connection with the foundations of these, but new designs have been prepared which will overcome these and give absolutely satisfactory structures, though at increased cost. Tenders were received for the main pipe-lines, but owing to the very high prices ruling at the time it was decided to invite fresh offers, which are closing in November, and we will undoubtedly save several thousand pounds on this item alone, consequent on the fall in prices that has occurred. Tenders for the main generating plant have been invited, and will be opened and considered shortly. At Arapuni, the proposed main supply for the Auckland Province, a vast amount of information has been collected during the year, and the results of this were submitted to a commission of engineers who visited and inspected the site of the proposed dam. These gentlemen decided that to make the dam doubly safe it would be advisable to amend the design somewhat, with a resulting increase in cost. The question of alternative sources was again very carefully gone into by my expert advisers in the light of revised costs, but the conclusions reached were that with any type of dam Arapuni was undoubtedly the most suitable source of power to develop for the Auckland District. At Waikaremoana contracts have been let for the supply of a plant of 1,000 horse-power capacity, and delivery of most of this plant is expected by the end of this year, and it is hoped to have it in operation before the end of 1922. This plant is part of the main generating plant, and will be used in part for the construction of the main scheme when started, and part for the supply of the Wairoa Power Board. For the general supply to the whole of the South Island a complete scheme has not yet been laid down. Schemes of supply from new proposed generatingstations at Lake Hawea or at the Teviot River have been considered in detail, but it has been decided that for some time to come the supply to Otago, Southland, and Canterbury can best be met by linking up and developing to their economic limit the existing developments at Monowai (Southland Power Board), and Waipori (Dunedin City Corporation), with the Government scheme at Lake Coleridge. Negotiations are now proceeding with the Dunedin City Council under which, if satisfactorily completed, they will further develop Waipori, and sell power in bulk to the Department for transmission to the various Power Boards proposed in the Otago District, and to join up with the Department's supply from Lake Coleridge at Timaru. For the supply to the northern end of the Island surveys have been made on the Clarence River, Waihopai River, Rotoroa (Gowan River), and Rotoiti Lakes, and other minor sources, and preliminary reports on these schemes prepared. Pending further survey and investigation work to be done in the Buller and Westland districts it is impossible to definitely lay down a general scheme, but the indications are that as soon as sufficient load develops a fairly economical scheme for the supply of Nelson and Marlborough can be developed on the Gowan River, the outlet of Lake Rotoroa.

Owing to the financial conditions prevailing and the consequent curtailment of some of the activities contemplated in my previous report the appointment of the special advisory Board mentioned therein has been held over pending the more active prosecution of hydro-electric development. Meanwhile the whole of the work of operation and management of the Department's existing plants, the investigation and design of new works and plant, and the construction of new works is being carried on by the staff of the Public Works Department, to whom I am indebted for their loyalty and energetic support during the last year. CONCLUSION. In conclusion, while regretting that the financial situation will not permit my carrying out all the work which the present favourable state of organization and supply of labour and material would permit, it has been my aim in drawing up my proposals to so allocate the available funds as to ensure prosecution of the projects which will lead to maximum production and generally produce the greatest good for the greatest number.

APPENDIX B. ANNUAL REPOKT ON PUBLIC WORKS BY THE ENGINEER-IN-CHIEF. The Engineer-in-Chief to the Hon. Minister of Public Works. Sir — I have the honour to submit the following repori upon the various works under my control completed and in progress throughout the Dominion during the period from the Ist June, 1920, to the 31st July, 1921. During the past year the improvement in the conditions of the employees, together with increased wages, has enabled us to obtain a better supply of labour. The labour-saving appliances which the Department procured have resulted in increased output, and generally the progress made in connection with public works has been much above the average of the last few years. The prices for material and labour have not yet receded to any substantial extent, and consequently the cost of works still remains very much above what it was in pre-war times.

Abstract— continued.

Kaihu Valley Railway Extension. (19 m. 17 ch. to 23 m. 71 ch. ; length, 4 miles 54 chains.) The formation on this line has now been completed with the exception of two or three culverts. Permanent rails have been laid from 21 m. to 23 m. 55 ch., and temporary rails from there into Donnelly's Crossing station-yard. The laying of the station-yard cannot be put in hand until the plat -girder bridge now in hand at 23 m. 58 ch. is completed. Two other permanent bridges have yet to be constructed, and traffic is at present carried temporary bridges. The first lift of ballasting has been completed to 23 m. 55 ch., and the second, lift from 19 m. 17 ch. to 22 m. Boxing-in has been completed to 21 m. Ballasting has been considerably hampered by shortage of plant, and we are at present carrying on with an outfit hired from the Railway Department. The construction of the station buildings has been delayed owing to shortage of timber, but thi; will now be supplied from our own mill which is being erected at Whatoro. A compressed-air tamping-machine for packing under the sleepers has been utilized on this work with satisfac'.ory results. A goods ervice from Tarawhati to Aranga was started in September, 1920, and settlers have taken full advantage of it. It is hoped to extend the service to Donnelly's Crossing in September, provided our own ballast-train is then available. Kawakawa-Hokianga Railway. Ngapuhi Northwards - Okaihau Section (16 m. 25 ch. to 24 m. 45 ch. ; length, 8 miles 20 chains). — The formation on this section has been finished, but continual trouble has been caused by slips due to the unstable nature of the country passed through. The large cutting at 19 m. 68 ch. and the embankment at 19 m. 53 ch. have been the most troublesome. A Marion shovel has been kept busy all the year shifting slips on this section. The embankment at 19 m. 53 ch. has required a lot of attention on account of the subsidence and the movement of the base ; it was therefore decided to remove a large quantity of the soft material to form a berm farther out, and fill in with fresh material from volcanic deposits. This has very much reduced the movement. All pipes and concrete culverts have been completed, and plans for the bridge over the Utakura Stream have been prepared, a temporary bridge being at present in use at this crossing. Ten miles of new fencing have been erected, in addition to alterations and repairs to existing fences. Platelaying has been completed to 26 m. 14 ch., leaving only a few chains and the Okaihu station-yard to complete the section, but the work has been delayed owing to shortage of material. A temporary ballast-line has been laid to the Utakura quarry, which has been opened up, and a quantity of stone got out in readiness for crushing and ballasting. The crushing plant has been erected, and is ready for operation. Okoro Section (24 m. 45 ch. to 34 m. 18 ch. ; length, 9 miles 53 chains). —Very little progress has been made on this section, owing to the shortage of labour, and the general reduction of men which took place toward the end of the period. Formation work between 25 m. 23 ch. and 25 m. 51 ch. was in hand, and about 15 chains were completed ; an 8 in. culvert at 25 m. 2 ch. was completed, and about 11 chains of fencing erected. Whangarei .Branch Railway. Oakleigh Section (5 m. 27 ch. to 7 m. 60 ch. ; length, 2 miles 33 chains). —Formation work on this section is now approaching completion ; two steam-shovels and several plough and scoop teams have helped to show good progress. The summit cutting at 6 m. 19 ch. was completed, and the deviation from 6 m. 78 ch. to 7 m. 29 ch. is well in hand. Rail-; have been laid to 5 m. 18 ch., including the Portland station-yard, and the second lift of ballast completed. The piers of bridge at 7 m. 33 ch. have been completed in readiness for the permanent girders. The platelayer's cottage which was being erected in concrete in the Oakleigh station-yard has now been finished. Tauraroa Section (7 m. 60 ch. to 14 m. 67 ch. ; length, 7 miles 7 chains). —The only work on this section during the period has been the removal of slips and general maintenance, but there is still a considerable amount of slip material to remove. The ballast-quarry at Tauraroa has been vigorously worked, and a large quantity of metal quarried and crushed for ballasting, road-metalling, and concrete-work on other Sections. A goods service has been run over this section, and in addition a regular wharf gang has been employed to deal with plant, material, and stores arriving at Oakleigh by sea from Auckland. Waiotira Section (14 m. 67 ch. to junction at Waiotira with the North Auckland Main Trunk Railway at 19 m. 67 ch. ; length, 5 miles 12 chains). —The main work on this section during the period has been the removal of slips from a number of bad cuttings, and the completion of two small deviations between 16 m. 40 ch. and 17 m. 10 ch. A Marion steam-shovel has been engaged on this

work for about seven months, and has shifted over 18,000 cubic yards, but the section of line between 16 m. and 17 m. 10 eh. is much the worst for slips in the whole length, and will fully occupy at least two shovels for a considerable time. In fact, it would have been exceedingly difficult to keep the line open without the steam-shovels. The shovel-work has been somewhat hampered by the shortage of wagons, but the position has been considerably eased by the arrival of some of the American dump wagons recently ordered, fourteen of the latter being now in commission, in addition to a number built locally. Four small Dinky locomotives have also been received, and are working in conjunction with the steam-shovels, enabling the work to be carried out more (xpeditiously and efficiently. A considerable amount of stone and tile drains will be required to drain the various slips and cuttings before finality is reached in this work. Fifty single huts and twelve married men's houses have been built. Waipu Branch Railway. Ruakaka Section (0 m. to 9 m. 20 eh. ; length, 9 miles 20 chains).— Formation was well in hand on this section, and an Erie steam-shovel was engaged in completing the banks across the mud-flats between om. and 2m. 45 eh. when work was stopped. This work has, however, been recently restarted. North Auckland Main Trunk Railway. Paparoa Section (88 m. 21 eh. to 92 m. 6 eh. ; length, 3 miles 65 chains). —The formation of this section has been completed, and all pipes, culverts, &c, are also completed. The big bank at 91 m. 30 eh. which gave so much trouble last year has now consolidated, and no further movement took place this winter. The excavation and lining of the Huarau Tunnel has been finished under very adverse conditions, the last section of lining being heavily reinforced to withstand the pressure, and conditions all through being such that progress was necessarily slow. The permanent rails have been laid to the end of the section, but the Paparoa station-yard sidings are still in hand. Ballasting operations were resumed during the period, and a first lift of ballast placed up to 92 m. 6 eh., omitting the bank at 91 m. 30 eh. Two platelayers' cottages were completed and occupied, and arrangements were entered into for four additional cottages and the Stationmaster's house. Mareretu Section (92 m. 6 eh. to 96 m. 45 eh. ; length, 4 miles 39 chains). —Trial surveys of these alternative tunnel routes and deviations beyond Golden Stairs and permanent surveys of the approved deviation were completed and plans submitted. A considerable amount of fencing on various portions of the section was erected, and arrangements were made with the settlers to enable work to Be put in hand as far as 96 m. 2 miles 12 chains of service road was constructed to serve the Golden Stairs Tunnel, and 10 chains of this will ultimately be used as the Golden Stairs to McCarroll's Road. Good progress has been made with the formation and culverts, but great difficulty has been experienced in keeping the section between Paparoa Station and Golden Stairs Tunnel free from slips and open for the service-train traffic. The clearing of slip at 92 m. 30 eh. and formation of bank at 92 m. 55 eh. is being carried out with a Marion steam-shovel; this work is almost complete, and the machine will then be transferred to cutting at 96 m. 37 eh. An Osgood shovel is being assembled, and will be utilized at 94 m. 25 eh. Platelaying is now complete to 93 m. 41 eh. ; ballasting operations were recommenced during April, and a contract let for procuring metal from the Hoteo quarry ; a first lift of ballast has been placed from 92 m. 13 eh. to 93 m. 41 eh. During the year forty-nine 8 ft. by 10 ft. huts, a new boardinghouse to seat fifty men, a recreation-hall, canteen, and water-supply have been constructed at Golden Stairs. Waikiekie Section (96 m. 45 eh. to 107 m. 28 eh. ; length, 10 miles 63 chains).—-Work has, as far as possible, been concentrated on this section during the year, and good progress has been made. From 100 m. to 102 m. 25 eh. the formation is practically complete, though several slips are developing, and will require removal. From 102 m. 41 eh. to the end of the section the formation, with the exception of the widening of the Waikiekie station-yard, has been completed. The cutting at 104 m. 18 eh. has, however, slipped badly, but a Marion shovel has been placed here and will soon have it cleaned up. Between 102 m. 40 eh. and 103 m. 5 eh. a Marion shovel has dug 21,000 cubic yards, and is still occupied on slips. A Bucyrus has been occupied at 106 m. 72 eh. in order to complete the bank to the Waiotira station-yard, but slips have again been troublesome. Every endeavour was made to finish the Waikiekie Tunnel during the period, and it was finally completed in April. Very great difficulty was experienced throughout in the construction of this tunnel, the ground being treacherous and unstable for the whole length. Owing to heavy slips at the northern end it became necessary to adopt a special reinforced section to enable the timber-work to be started, and particularly close and heavy timbering had to be used throughout. All material for the south end of the tunnel and for works ahead was hauled over the top of the tunnel by means of a rope tramway. This proved economical, and enabled preparations to be put in hand for the Mareretu Tunnel. As soon as the north end of the Waikiekie Tunnel was completed a start was made with the Mareretu Tunnel ; and, as preparatory work and accommodation, including boardinghouse, recreation-hall, and water-supply, were well in hand, it was possible to transfer the men on the north end of Waikiekie to Mareretu while the men on the south end of the former were completing the last length. At the end. of the period 3 chains of the Mareretu Tunnel were completed, and it is anticipated that the remaining 13| chains will be completed by the end of next June. A certain amount of difficulty was experienced in driving through the soft ground near the approaches, and it was necessary to use two sections for the concrete lining, but as both headings are now in fairly soft ground no further trouble is anticipated. The piers for bridges at 104 m. 1 eh. and 104 m. 35 eh. have been completed, and temporary superstructures placed pending the arrival of the steel girders, which will be placed in position as soon as received. Preparatory work for the erection of bridges over the Mangawai River and Kikowhiti Stream is in hand.

The small crashing plant at 104 m. 4 oh. has turned out 12,000 cubic yards of metal for various purposes. The permanent rails have been laid from 106 m. to 104 m. 26 eh., and the temporary track is being gradually replaced with permanent line. A light service line has been put in from 104 m. fi oh. to 102 m. 20 eh. in order to get materials to Mareretu Tunnel. Ballasting has been in hand between 106 m. 60 oil., and fair progress was made. Between 104 m. and 102 m. 30 eh. 1 \ miles of road has been metalled and 4| miles of fencing erected. The Stationmaster's house at Waiotira station-yard has been completed. Difficulty was experienced during the year in obtaining timber for the construction of workmen's huts and other buildings, while a shortage of carpenters delayed, erection. The opening of the sawmill has, however, eased matters considerably, 268,000 ft. of timber for huts, temporary sleepers, and tunnel-work having been supplied ; 105 single huts, fifteen married men's houses, and three cookhouses have been built; and, although each individual has not been provided with a hut, still a great improvement has been effected in the housing of workmen. A survey of a deviation from the Mareretu station-yard to 99 m. has been completed, and as soon as a steam-shovel is available it will be transferred to the cuttings on this portion. Kirikopuni Section (107 m. 28 eh. to 121 m. 40 eh. ; length, 14 miles 12 chains).— Comparatively little work has been carried out on the southern end of this section, as operations were stopped in January in order to concentrate on the "Waiotira Southwards Section. A Bucyrus steam-shovel was in operation for five months, and dug 9,600 cubic yards to bank. On the northern end of this section a tramway has been constructed from the Wairoa River to the Omana Tunnel, a distance of 2 miles 60 chains. A limestone-quarry has been opened up, and it is intended to lightly ballast this tramway in order to allow a locomotive to be operated between the river and the tunnel. The northern approach to this tunnel has been commenced, and a new Osgood shovel will be started in here very shortly. 140 chains of permanent fencing were erected. Waiuku Branch Railway. Glenbrook Section (5 m. to 8 m. ; length, 3 miles).—Platelaying, and the first and second lift of ballast, have been completed on this section. Cattle-stops and road-crossings have been completed, and the station buildings at Glenbrook erected. The completed portion between Patumahoe and Mauku Station has been maintained, and the goods service has been extended to Glenbrook. Waiuku Section (8 m. to 12 m. 15 eh. ; length, 4 miles 15 chains).--Formation work and platelaying have been completed, also the first lift of ballast to the end of the section, and the second lift to" 10 m. Ballasting operations have been greatly hampered by the uncertainty of supplies from the Railway Department, who have only been able to supply at irregular and infrequent intervals. Concrete overbridge at 10 m. 74 eh. has been completed, and that at 11 m. 30 eh. is well in hand. Station buildings at Pukeoware and Fernleigh, as well as the Stationmaster's house at Waiuku, are finished, while the goods-shed and platelayers' cottages at Waiuku are Hearing completaion. HUNTLY-AWAROA RAILWAY. (7 m. 20 eh. to 10 m. ; length, 2 miles 60 chains.) Formation work is in hand between 7m. 26 eh. and Bm. 62 eh. Ten culverts have been built, and the fencing has been commenced. Road-widening on the right-hand side between Bm. 22 eh. and Bm. 34 eh., as well as access road at Bm. 46 eh., has been completed. Further surveys in order to provide for station-yard and mine sidings have been made, and permanent line relocated and pegged. East Coast Main Trunk Railway. Waihi Eastwards - Athenree Section (0 m. to Bm. 68 eh. ; length, 8 miles 68 chains).—Practically all the formation on this section has been completed with the exception of a few very minor works such as the completion of several bridge approaches. The erection of the Mangatoetoe Bridge was commenced in June, and nine pier excavations have been finished, of which three have been concreted to ground-level. This work necessitated the removal and re-erection of the public footbridge over the Mangatoetoe Creek. Katikati Section (8 m. 68 eh. onwards). —Fair progress has been made with the formation and culverting, and this is now complete from 8 m. 71 eh. to 10 m., with the exception of a small block in cutting at 9m. 18 eh. The formation is also complete between 11 m. 65 eh. and 12 m. Tawanga Westwards - Tauranga Section (36 m. to 41 m. 5 eh. ; length, 5 miles 5 chains).—About 1$ miles of formation, together with fencing and drainage, have been completed between 36 m. and 39 m. 55 eh. The toes of banks between 35 m. 50 eh. and 36 m, 10 eh., where abutting on tidal water, have been protected with fascines, and a quarry has been opened up on the Wairoa River about 3 miles above the traffic-bridge, in order to supply stone ■ for facing banks on this section. The erection of three platelayers' cottages in the Tauranga station-yard has been commenced. Tauranga Eastwards ~ Matapihi Section (41 m. 5 eh. to 45 m. ; length, 3 miles 75 chains).—Good progress has been made on the bank between 41 m, 27 eh. and 41 m. 74 oh. : this has been extended about 4 ft. below formation-level to 41 m. 38 eh. and stone-pitched to the same point. The stone riprap wall has been carried out to the Tauranga Bridge pier. All cylinders for the Tauranga Bridge have been completed, and twenty-four have been sunk to the proper depths. Staging has been erected for seven piers, and a total of 442 ft. of reinforced cylinder constructed, of which 386 ft. has been sunk. Considerable extra work was entailed in the sinking of the cylinders owing to the very soft material met with, thus entailing extra lengths of cylinder over and above that anticipated. However, with the exception of abutment P all cylinders are now on a satisfactory bottom.

Mount Branch (0 m. to 4m. 7 eh. ; length, 4 miles 7 chains). —The regular goods and passenger service has been carried on over this section in a satisfactory manner, and the line has been well maintained. A considerable amount of work has been carried out in connection with the restoration and extension of the workshops ; the filling-in for yard-extension has been completed, and platelaying is in hand. The new mill and carshop is almost completed, and the blacksmith's shop is in hand. A considerable amount of new heavy-duty machinery has been installed, and the shop is now well equipped and efficient. In addition to the steelwork for the Tauranga Bridge and seven smaller bridges, a great deal of timber and iron work has been carried out, including the manufacture of an orange-peel grader, three large piling-derricks, concrete buckets, earth wagons and trucks, dredge-punts, and the assembly of steamshovels, caterpillar tractors and trailers, &c. The general machine repairs and maintenance to locomotives and rolling-stock have been a heavy item ; nearly all the M ballast-wagons having had new underframes, and their wheels turned up. A new water-supply, including engine and pump, was erected at the workshop to serve locomotive and workshop boilers, and provide a domestic supply for workmen. Te Puke Section (45 m. to 54 m. ; length, 9 miles). —This section has been kept open for traffic, and, in addition to ordinary maintenance, all the bridges have been repainted, and the Mangatawa drain cleaned out, deepened, and extended. About 10,000 yards of metal has been quarried and crushed, part being supplied to local bodies and part used for ballasting and concrete-work by the Department. Paengawa Section (54 m. to 59 m. 67 eh. ; length, 5 miles 67 chains). —This section has been maintained for traffic, and additional waterway has been provided at Wairi Bridge. Pongakawa Section (59 m. 67 eh. to 64 m. ; length, 4 miles 13 chains). —No work has been done on this section beyond maintenance for traffic.

Mangahao dam : The foundations on the line of spillway as at first set out proved on testing not to be what was expected, and further test-pits have been sunk on another line. Tokomaru dam : The same remarks as above apply to the foundations of this dam. Pipe-line : Fair progress has been made with the excavation, 3,100 ft. having been formed. The tram-line by means of which the pipes and cement, &c, will be conveyed is also nearly completed. Surge-chamber : A start was made with the excavation of the top portion in April; progress to date, 1,404 cubic yards. Power-house : Fair progress has been made with the excavation; progress to date, 2,833 cubic yards. Transmission-line: Poles have been delivered at the railway-stations between Shannon and Wellington for the main transmission-lines. Construction plant, Mangaore : A 250 kw. steam set supplied by two Babcock and Wilcox boilers has been in operation since the end of May. The work was delayed by the fact that the generator did not arrive from England until the 2nd May. An air-compressor of 600 cubic feet per minute displacement has been installed to supply air to the works in that vicinity and as far as the second adit of the Arapeti Tunnel. A workshop has been erected and fitted with various machine tools for the purpose of keeping the plant in running-order. A transmission-line has been erected from Mangaore via the surge-chamber and Arapeti to Mangahao. The necessary transformers have been provided, so that practically all the machines will eventually be driven by electricity. Owing to the delay in obtaining the machinery for the main power-house it was necessary, in order to get a start with the Mangahao Tunnel, to install a 60-h.p.-boiler Marshall engine, and aircompressor of 300 cubic feet displacement, at the bottom of the gorge. Considerable difficulty was experienced in getting this heavy plant into such an out-of-the-way locality. A jig-line with a fall of 460 ft. and an average inclination of about 40° was erected for the purpose of lowering material into the gorge. The Marshall engine has now been replaced by a 60 h.p. motor, and the boiler is being used to provide steam for drying-rooms, showers, &c. Staff accommodation : Four permanent cottages, a bachelors' quarters, and an office have been built, and a sewerage system installed, to which the above buildings have been connected. Workmen's accommodation : The following have been built: Drying-rooms at Arapeti and Mangahao ; cookhouses at Mangahao, sawmill, and Arapeti; recreation-hall at Arapeti; married men's cottages—Nine at Arapeti, eight at Mangaore, and seven under construction, also one at sawmill; single men's huts—Nine eight-men huts at Arapeti and two at Mangaore, also two fourmen huts and two two-men huts at Arapeti, and eight two-men huts at the sawmill. Service buildings : In addition to the buildings housing the ] plant, a large bulk store has been built at Mangaore, and a smaller one at Arapeti. A garage for six lorries at Mangaore and an explosives magazine at Arapeti have been built. Sawmill: The output of the mill for several months was very costly and poor, but now better bush has been opened up, and costs should show a rapid decline. For the twelve months 651,505 superficial feet of timber was cut. A total of 142 chains of tram-lines have been formed to enable logs to be got from the bush to the mill. The average number of men employed on the works has been 201-673. Waikaebmoana Power Scheme. A considerable amount of widening and metalling has been done on the main road from Wairoa to Waikaremoana in anticipation of the heavy traffic anticipated in connection with the construction of this scheme. Material has been ordered, and preparations are being made for rebuilding most of the smaller bridges on this road. The formation of roads to give access to the power-house and to the headworks has been completed, and material for two bridges over the Waikaretaheke River has been ordered. _ Contracts have been let for the supply of the pipe-lines and machines for two 500 kw. units, which will supply power for construction purposes on the main scheme, and also supply power to the Wairoa Power Board in the meantime. The delivery of this material is expected about the end of 1921, and it is hoped to have it in operation before the end of 1922. Lake Coleridge Power Scheme. During the year further deepening was carried out in the lake at the tunnel intake. A start was made with the work of diverting a portion of the Harper River into the lake, and a channel, 1J miles long, from the Harper River to the lake was excavated, and the water was turned into the channel in March, 1921. Preparation is now being made for the construction of a large groyne in the riverbed to permanently divert the river on to the bank from which the channel leads to the lake. The fifth unit (3,000 kw.) was completed during the year, but the machine could not be put into operation until the third pipe-line was completed. This work is now well in hand, and it is anticipated that this machine will be in operation shortly. As part of the scheme for transmission of power to Timaru, the poles have been erected from the power-house to the Point, a distance of about 12 miles, and the material for the balance of the line to Timaru has been ordered, and work on the erection will commence at an early date. A further length of 4 miles of 11,000-volt distribution-line has been erected in the North Canterbury district. Arapuni Power Scheme. A series of drives on the sides of the gorge under the river and along the line of the proposed diversion-channel have been completed. A considerable amount of prospecting and excavation for possible quarry-sites in the neighbourhood has been carried out. The question of the feasibility of erecting a dam of the dimensions required at the site in question was referred to a committee of engineers and geologists, who visited the site and examined all excavations and data and reported favourably. This scheme has now been definitely adopted as the main running-power for the northern portion of the North Island.

AP'PE-NDIX C. ANNUAL REPORT ON BUILDINGS, BY THE GOVERNMENT ARCHITECT. The Government Architect to the Hon. the Minister of Public Works. Sir,—I have the honour to submit the following report on the various building operations of f the Department for the year ended 31st March, 1921. New Parliament Buildings. During the year 5,622 cubic feet of stone was worked and 5,909 cubic feet was set, the principal stonework being the completion of the two north features on the Molesworth Street and Museum Street frontages, the columns and cornice over loggia, the columns and capital stones at the front entrance, and the balance of columns in the Legislative Council chamber. The corridors and rooms on the ground floor of the Museum Street front, the Speaker's suite, and the corridors and rooms on the ground and first floors have been completed. A considerable amount of brickwork was carried on, and the covering of the roofs of the loggia and post-office, as well as the making good of the holes in the floor and roof caused by dismantling the cranes, was completed, and the final asphalting of all roofs » is well in hand. Electric light, power mains, and heating plant were installed in the newly finished portion of the building, and temporary partitions were erected at the main entrance to enable work to be carried on during the session with as little inconvenience to members as possible. A contract was let for the supply and fixing of the , ornamental marble for entrance-hall and lounges. Good progress has been made during the latter part of the period, and it is anticipated that the building will be fully completed for the session of 1922. Vice-Regal Residences. Auckland. —The interior of the residence has been altered and renovated, and the exterior and outhouses repainted. The promenade in front of residence has been renewed in concrete. New W.C. has been fitted at Lodge Cottage, and the yard has been asphalted. Two motor-garages and storeroom for meat and vegetables have been erected. New blinds have been provided. Men's quarters have been provided at the stables. Wellington. —Extensive alterations were effected to this building, and considerable additional accommodation provided, principally with a view to furnishing offices for His Excellency the GovernorGeneral and staff, and providing additional accommodation for the servants. Additions were made to the laundry, and a bath and additional lavatory accommodation was installed in the attic rooms. Arrangements were made for the heating of the linen-presses, and towel-rails and hot-water racks were installed in the bathroom and pantry. Twelve rooms were papered, and the head gardener's cottage was renovated, papered, and painted. Two rooms in the maids' cottage were papered. The upper and lower reservoirs were cleaned out and cement-washed, and the plumbing-work throughout the building was overhauled. A number of the rooms were subdivided to furnish additional accommodation. A shed with concrete floor was erected for. the gardener's use, and the main drive was' widened. A new floor was put down in the bathroom in the west wing, and the bath was refitted. The carpets in various rooms were taken up, cleaned, and relaid. New pipes for the hot-water service were put in to remedy the discoloration of the bathroom, and a new porch was erected at the entrance to the ball-room. A new strong-room was constructed. A skylight was put in in the ironing-room. Repairs were effected to various parts of the roof, and the drains were inspected quarterly. The road , round the grounds was repaired and metalled, and the iron fence enclosing the asphalt tennis-court was removed at the request of the Governor-General. The whole building was cleaned up generally in preparation for the new Governor-General's occupation, and his furniture was unpacked and placed in position. Departmental Buildings. Auckland. —General repairs have been carried out to exterior of Customs Buildings, and all wood and iron work painted. Yards have been repaired, tarred, and sanded. Alterations have been carried out and a large range of fittings supplied to the Lands and Survey, Department, North Auckland. The strong-room has also been altered. The Public Works Stores Department have been removed to their new quarters in Shaw-Savill's Buildings, and all necessary alterations carried out. Alterations have been carried out to the first floor of the Law Court Buildings to accommodate tenants who have been transferred from the third floor. Preparations are being made to accommodate the Valuation Department on the third floor.

APPENDIX D. ANNUAL KEPOKT OF CHIEF ELECTRICAL ENGINEER. The Chief Electrical Engineer to the Hon. Minister of Public Works. Sir, — I beg to report on the position of the electric-power developments of the Dominion for the past year as follows : — General Power Requirements. The general scheme of hydro-electric development for the Dominion as laid out by my predecessor is based on an estimated demand of one horse-power delivered to each five head of population. In estimating the generating-power required to deliver this amount an allowance is made to cover losses amounting to 23 per cent, of the power delivered. On the basis of the. 1916 census the following total power is thus required for the supply of the whole Dominion : — North Island. South Island. Total. Population .. .. .. ..650,000 450,000 1,100,000 Horse-power delivered .. .. 130,000 90,000 220,000 Horse-power generated .. .. 160,000 110,000 270,000 The 1921 census indicates an increase on these population figures of 14 per cent, for the North Island and 6J per cent, for the South Island, including all returned soldiers not included in the 1916 census. As the schemes already worked out in detail on the basis of the 1916 census allow a reasonable margin for development, it is not desirable to recast them at this stage, but the more rapid increase in the North Island than in the South Island must be taken into account. At the same time, the estimate of 0-2 h.p. per head of population must not be considered as an ultimate limit to the demand, which, owing to the favourable opportunities for cheap hydro-electric developments in the Dominion, will ultimately reach a much higher figure. Canada already has an installed capacity of 0-274 h.p. per head. California has an installed capacity of 0-53 h.p. per head, and it is estimated that by 1930 this will have been increased to 0-8 h.p. per head of population. The proposed hydro-electric developments in New Zealand are as economical as those in Canada, and generally more economical than most of those in California, and developments may therefore be anticipated here at least to the same capacity as in Canada. But in the meanwhile the basis of 0.2 h.p. per head is fairly ample, being approximately twice the power now used in Christchurch and Dunedin, which have been supplied with fairly cheap hydro-electric power for some years. Main North Island Scheme. In order to supply this power for the North Island a complete interconnected scheme was laid out by Mr. Parry, consisting of 1,112 miles of main transmission-lines and 309 miles of branch lines. For the main transmission-lines the distances and quantities of power to be transmitted involved the adoption of a pressure of 110,000 volts, and for the branches a pressure of 33,000 volts, except for the Waikato branch, where a pressure of 50,000 volts was already in operation from the Horahora power plant. This network is to be fed from three main points, viz. : — Proposed Ultimate Development. Capacity. Horse-power. Horse-power. Mangahao River .. .. .. .. ..24,000 24,000 Waikaremoana .. .. .. .. ..40,000 136,000 Arapuni .. .. .. .. .. .. 96,000 162,000 Totals .. .. .. .. 160,000 322,000 This system is to be connected up ultimately with the existing hydro-electric-power stations at Horahora (8,400 h.p.), New Plymouth (1,000 h.p.), and Wairua Falls (2,600 h.p.). The estimated cost of the whole North Island system, based on 12 per cent, excess over pre-war prices, was as follows :— Amount. Per Horse-power. Power-stations — £ £ Mangahao (24,000 h.p.) .. .. .. .. 438,654 18-30 Waikaremoana (40,000 h.p.) .. .. .. 544,369 18-16 Arapuni (96,000 h.p.) ... .. .. .. 1,078,700 10-80 Total power-stations (160,000 h.p.) .. .. .. 2,061,723 12-88 Main transmission-lines : 1,112 miles at £1,400 per mile .. 1,553,880 i Branch transmission-lines : 309 miles at £780 per mile .. 241,360) l Main substations .. .. .. .. .. 5-24 Distribution-lines and secondary substations .. .. 2,086,000 13-04 Interest during construction .. .. .. .. 271,271 1-69 Working capital .. .. .. .. .. 250,000 1-56 Totals .. .. .. .. £7,303,042 £45-63

It was estimated that it would take ten years to carry out this work, and that the annual cost, allowing 1\ per cent, for capital charges (interest, depreciation, and sinking fund) and £220,000 per year working-expenses, would be £5-9 per horse-power year— practically £8 per kilowatt-year. The present actual costs are proving to be over 50 per cent, in excess of pre-war costs instead of 12 per cent., and the following statutory authorizations have been made enabling this whole North Island scheme to be undertaken :— Electric Power Works Loan Act, 1919—- £ Arapuni Electric-power Works .. .. .. 4,500,000 Mangahao Electric-power Works .. .. .. .. 1,600,000 Horahora Electric-power Works .. .. .. .. 412,500 Waikarernoana surveys .. .. .. .. .. 30,000 Finance Act, 1920— Waikarernoana Electric-power Works. . .. . . .. 2,600,000 Kaituna River Electric-power Works .. .. .. 150,000 Other surveys and investigations .. .. .. .. 30,000 £9,322,500 Towards the carrying-out of this programme the position at the end of the financial year under review is as follows :— The Horahora plant (8,4.00 h.p.) and main transmission-line to Waihi (50 miles) have been purchased from the Waihi Gold-mining Company for £212,500, and the extensions of the lines to Cambridge, Hamilton, and Te Awamutu have been carried out. It is also proposed to extend the Horahora power plant by the addition of another two units of 2,600 h.p. (2,000 kw.) capacity each, bringing the total capacity of the plant up to 13,600 h.p., for which capacity water will be available except for limited periods in exceptionally dry years. Supply was commenced to Cambridge on the 28th April, 1921, to Hamilton on the 31st May, 1921, and to Paeroa (through the Thames Valley Power Board) on the 29th March, 1921. Lines have also been erected to To Awamutu and Te Aroha, and the necessary material is on order for the first of the main 110,000-volt lines to Auckland. This will be supplied in the meanwhile by power from Horahora, giving an emergency supply for the essential industries of the city. Negotiations for a substation site near Penrose are in hand. Mangahao. —The Mangahao headworks have been pushed on during the year. Tenders were invited for the pipe-lines, but owing to the falling market it was decided to call fresh tenders closing on the Ist November, 1921. Specifications for the balance of the plant have been ready for some time, but for the same reason were held back until it was anticipated more reasonable prices would be available, and tenders were invited accordingly, and closed on the 29th November, .1.921. The transmission-lines poles are being delivered. The land for the main substation for the Wellington District has been secured. Arapuni. —At Arapuni Gorge further investigations and exploration drives have been carried on throughout the year. The results were submitted to a committee of engineers, on whose suggestions the quantity of concrete in the proposed dam has been increased to render it safe as a gravity dam apart from its strength as an. arch dam, and this work is now ready to be proceeded with. Suitable deposits of sand, shingle, and rock have been located for the necessary concrete. Waikaremoana. —At Waikarcmoana the approach roads and bridges are in hand, and the power house surveys carried on. The two permanent exciter units of 500 h.p. each have been ordered, and it is proposed to erect these in a temporary power-house as soon as they arrive, and to utilize them for the construction of the permanent works and for commencing supply to the Wairoa Electric Power Board. Portions of this material have already arrived in the Dominion. At Rotorua (Kaituna River scheme) surveys have been completed, but owing to the financial stringency and to the fact that the supply to Rotorua requires augmentation before this scheme could be completed, tenders have been called for a 200 h.p. Diesel engine plant for installation in the town. The total expenditure on all the North Island schemes and surveys to the 31st March last is as follows :— Expended during Total Expenditure the Year ended to 31st March, 31st March, 192.1. 1921.

South Island Schemes. No Comprehensive scheme has previously been drawn up for the South Island, and it has not been possible yet to bring the investigations to the stage of a final decision as to the sources of power, but sufficient information has been obtained to enable the general outlines of such a scheme to be laid down for the Canterbury, Otago, and Southland portions of the Island. It will consist ultimately of a completely interconnected transmission-system generally on the same lines as the North Island scheme, and supplied with power from four or five main power-houses and two or three subsidiary sources. The population of the South Island according to the 1916 census was 448,377, and the amount of power required on the same basis as adopted for the North Island —viz., one to five —is 90,000 h.p. Allowing 22 per cent, of the power delivered for losses in distribution, the generated horse-power required is 110,000, as compared with 160,000 for the North Island. The growth of population is not so rapid in the South Island (only 6|; per cent, for the five-years period since the 1916 census, as compared with 14 per cent, for the North Island). Moreover, the population in the South Island is more concentrated round certain definite centres, and the main power sources already in operation are nearer these centres of population than those proposed for the North Island. These considerations, combined with the smaller power to be transmitted, point to a lower standard voltage than the 110,000 volts adopted for the North Island. The transmission-pressure already adopted for the Lake Coleridge system and the proposed Southland (Lake Monowai) system is 66,000 volts. This is the highest pressure for which pin-insulator construction is reliable, and this type of construction has a great advantage in first cost over the 110,000-volt suspension-insulator type of construction which has been necessary for the larger powers and. longer distances to be transmitted in the North Island. The minimum length of the pole is reduced from 52 ft. to 42 ft., and in this and other directions a saving of about £400 per mile is possible in standard transmission-line construction with the lower voltage. The present transmission-pressure from Waipori Falls to Dunedin, a distance of only 30 miles, is 35,000 volts, but this is too low to be extended economically into general transmission-system. Surveys are sufficiently advanced to enable a comprehensive scheme to be drawn up for the Canterbury, Otago, and Southland Districts. For the other portions of the Island the surveys are still in hand, and definite proposals cannot yet be laid out. For Canterbury, Otago, and Southland the main 66,000-volt transmission-system proposed is shown on the map herewith, amounting to a total of 759 miles, made up roughly as follows : — Miles.

It will be noted that there are several largo loops in this system, giving the advantages of a duplicate supply to the majority of districts even when a single line only runs through them. From this main 66,000-volt system supply will be given to the various Power Boards or reticulating authorities, who will be responsible for the secondary 33,000-volt, 11,000-volt, or 3,300-volt feeders and the low-tension distributors. On the main 66,000-volt transmission-system, substations will be located at intervals of 20 to 60 miles according to the demand ; but in general it will not be economical to tap the main line unless there is a demand, immediate or in view, for at least 300 h.p. from each such substation. From these main substations supply will be given to the Power Boards at 11,000 or 33,000 volts. At the former pressure the feeders will have an economical range of 20 to 25 miles, and at the. higher feeder-pressure a range of 40 to 50 miles for small amounts of power. These ranges from the main 66,000-volt substations with the network described above will economically cover practically the whole districts concerned. There will remain a few isolated spots, such as Quccnstown and Hanmcr, which can be more economically dealt with by a small local water-power plant, but with the Power Board organization set out in my previous annual report the requirements of the whole Island are taken into account. The balance of the South Island consists of the settled districts round Blenheim, Nelson, Westport, Greymouth, and Ilokitika, with the very sparsely settled areas between. Taking the whole of the population, both town and country, into account, the following is the total demand, based on the very ample allowance of one horse-power to live head of population ; and in these sparsely settled districts it will take many years to reach this stage of development:— District.

But these districts differ from the rest of the Dominion in that the demand is more concentrated near the towns. There is very little dairying except just round the centres of population ; these centres are more widely separated ; the connecting roads are very rough., mountainous, and difficult for transmission-line construction and maintenance, and, above all, there are local water-powers near each centre which, with one exception, can be developed very cheaply up to the capacity required for ordinary domestic and industrial purposes for many years to come. No doubt the completely interconnected scheme provided for the rest of the Island will ultimately be extended to these centres as well, but the above circumstances render it impossible to justify main interconnocting-lines between these small centres at present, and full surveys of each district are necessary. The local sources that •have been proposed are as follows : — Ultimate Capacity. Marlborough District— Horse-power.

It is proposed during the coming year to carry these surveys on to the stage at which a definite decision can be made of the most economical sources of supply for these districts. Waikato Electkic-powek Supply. The Horahora plant was acquired by the Department from the Waihi Gold-mining Company on the Ist November, 1919, and operated by the company for the live months ending 31st March, 1920, so that the year ended is the first complete year of operation by the Department. Financial Results of Operation. The capital outlay at the end of the year was £249,715, exclusive" of stocks of material for new work, as compared with £215,064 on the 31st March last. This is analysed in Table A. Cost and load records are given in Table B. Future Prospects. A contract has been entered into with the Grand Junction Company under which the Department undertakes to supply the company with power during the night hours and when it is available during the day —that is, until the demand of other consumers, including the Waihi Company, grows approximately to 6,000 lew. When the load of the Department's ordinary consumers grows beyond the capacity of Horahora, the Grand Junction Compa.ny will supply power to the Department, generated at its steam plant at Waihi, up to an amount not exceeding 2,000 kw., above the requirements of the mine. Supply to this consumer commenced in January, and so far is only for a partial supply of about one-third of its total demand. Another contract, with provision for use of standby plant, has been made with the Cambridge Co-operative ■ Dairy Company, in connection with their plant at Hautapu. A contract has been made with the Thames Valley Power Board for supply to them at Waikino, and arrangements are being made to supply the Thames Valley Board at Horahora and Wuihou, the Te Awamutu, Cambridge, and Central Power Boards, Hamilton Borough Council, and the Railway Department's factory at Frankton. After providing for the requirements of the Waihi Gold-mining Company, and reserving 500 h.p. for special industries and 200 for the Arapuni works, and allowing for one spare unit of 1,400 h.p., there is left for allocation to the different Power Boards 2,400 h.p. out of a, total of 8,400 h.p. As far as possible the spare unit will be utilized to supply power to factories, &c, which already have steam plants installed and can be cut off in case of necessity without any great inconvenience. Such factories arc the Hautapu Dairy Factory mentioned above, and the New Zealand Co-operative Dairy Company's factories at Frankton, Waitoa, Waharoa, and Te Awamutu. Extensions. Transmission-line construction was commenced in November on the Horahora-Hamilton 11,000--volt line, which has been completed to Cambridge and Hamilton. Orders have been placed for material for the following extensions, all of which should be completed within the next year : — Horahora Power-station. —Additional transformers and switch gear required to supply at 11,000 volts. Transmission-lines.- -11,000-volt lines to Cambridge, Hamilton, and Te Awamutu, a total of 32 miles (approximately) ; 50,000-volt lines from Horahora to Hamilton and Te Awamutu, and from Waiorongomai, on the Horahora-Waikino line, to Waihou, a total of 46 miles (approximately). Substations. —50,000-volt to 11,000-volt equipment for substations at Waihou, Hamilton, Waikino, and To Awamutu.

Power-house Extensions. —Designs have been prepared for extensions (two 2,000 kw. units) to the power-station at Horahora, and tenders for the supply of the plant for these extensions are. closing early in 1922. Operation Headworks and Power-house. During the Christmas shut-down the opportunity was used to examine the race, and to alter the screens to prevent them being choked by weed and pumice, of which a considerable amount is brought down in flood-time. The indications are that considerable improvement has been effected. The turbines have all been overhauled, and adjustments made which have improved their operation and particularly the governing. Tests have been made on the power-house working on artificial load up to its full capacity. When this was first tried, full load could be maintained only for a few minutes, owing to the badly blocked screens causing the water in the turbine-pits to drop. Since the alterations to the screens the plant has carried full load for several hours without any difficulty, but at extreme low water the most that can be carried is 5,700 kw., showing that to utilize the increased plant capacity at low water it will be necessary to extend the wing-dam and weir at the intake. Provision is being made for this work. Measurements made on the water left in the river at the time of this test indicate that the total power obtainable at Horahora, with reconstructed dam and increased head, is about 8,400 kw. at the low-water period. Transmission-line. Various defects in the transmission-line have been remedied with good results. Some of the towers have been tarred as a protection against the weather, but much remains to be done in this direction. This work is difficult to carry out, as the time during which the line can be made " dead " for this purpose is very short. Interruptions lo Service. Apart from the shut-down for overhaul for 41 hours 7 minutes at Christmas, the total number of interruptions was twenty-three, for a total time of 45 hours 26 minutes ; eight of these were of 1 hour duration or more, for a total time of 38 hours 14 minutes. Three breakdowns only were due to insulator trouble, the rest being due mostly to mechanical faults and defects in apparatus which have been remedied. There have been no troubles on the Thames Valley Power Board's 11,000-volt line, Waikino to Paeroa, or on the 11,000-volt lines from Waikino to the Waihi Mine and the Junction Mine.

Table C. — Total Connected Load in Kilowatts, Horahora.

Lake Coleridge Hydbo-electric Supply; The year ending 31st March, 1921 (the sixth year of operation), has again closed with a credit balance after paying all charges. The year was abnormally dry, and no .serious snow troubles were experienced through the winter; nevertheless, considerable transmission-line trouble was experienced as a result of insulatorfailures, the failures being approximately 50 per cent, more than in the previous year. The plant, though operating under conditions of heavy overload for the major portion of the yc.-u , , has stood up well to its work, and Las been maintained in an efficient condition. The revenue for the year was £51,373; working-expenses, £21,341 ; Capital charges, £18,639; and allowing £7,946 for depreciation, this yielded a credit balance of £3,447 in excess of all charges. Capital Outlay. The capital outlay to the end of the year was £499,957, as against £422,076 for the previous year. Details of this expenditure are shown in Table E. Financial Results of Operation. Table D gives the financial results of operation and load records. It will be noted that the powerhouse maximum shows an increase of 6| per cent., and units output of 10 per cent, over that of the previous year owing to the load factor being improved from 59-9 to 61-4 per cent. The total gerierating-eosts per unit generated and per unit sold show an increase respectively of 0-07 d. and 0-05 d. These increases are accounted for in the main by (1) Increased interest payable ; (2) increases in salaries and wages ; (3) additional demand made on standby plant owing to linefailure ; (4) transmission-line maintenance being 50 per cent, in excess of previous year. Table F shows the operating-costs for the year under consideration as compared with those of the previous year, and Table G gives the gross financial results of distribution of energy. Extensions. No. 5 generator of 3,000 lew. capacity arrived and was placed in position and coupled up to its turbine. All the material for the third pipe-line is to hand, and the contractors commenced erection in September, 1920, and completed it in August, 1921. A start has been made on the erection of a switching-station at Windwhistlc. This is the distribution station from which the South Canterbury line feeding Timaru and Oamaru (ultimately linking up Waipori), and the North Canterbury line to Kaiapoi via Sheffield and Oxford, will be fed. A small breakdown station is also being erected at this point for local reticulation. The erection of the third main transmission-line between the power-house and Christchurch has also been started, and provisional surveys made on the North and South Canterbury routes. Whilst the supply of power available has been limited, nevertheless 11,000-volt reticulation has increased from 72$ miles to 77| miles, and the City Council has increased its 11,000-volt underground feeders from miles to 19 miles. No additions have been made by the Department to the 3,000--volt lines, but local bodies supplied by the Department have increased their 3,000-volt lines from 65 miles to 70§ miles. Connected Load (Table H). The total connected load increased to 34,277 kw., or 12.1 per cent, increase on that of the previous year. This load made a maximum demand on the substation of 6,712, which gives a diversity factor of 5-10, a very high figure, due to the encouragement of off-peak loads. Operation. The operation of the plant at Coleridge has, owing to the continuous heavy demands on it, entailed incessant care, and the greatest credit is due to the Superintendent and his staff for the excellent results obtained. A considerable measure of anxiety was occasioned early in the year under review by the undue wear on turbine liner-rings of Nos. 3 and 4 units. This was brought about .through the excessive fall in the lake, necessitating continuous work on the lip of the rock at the mouth of the intake. As a result, considerable quantities of sand and shingle were carried down through the machines. New liner-rings were made locally and installed with satisfactory results. A test taken on the machines in March, 1921, gave an over-all efficiency, surge-chamber to tailrace, of 71 per cent., which under the circumstances can be regarded as satisfactory. The maximum load recorded at the power-house was 7,420 kw., representing an overload of 24 per cent, on each of the four generators.

Curves showing Variations in Lake-level.

9—D. 1.

The transmission-line insulators have given every indication of progressive deterioration, and during the latter portion of the year, prior to completion of the annual overhaul, breakdowns occurred frequently. A rigorous overhaul and replacement of insulators showing signs of defect has resulted in a very pronounced improvement in this respect. The year passed without any serious troubles occurring on the lines, and all operating equipment has worked satisfactorily. Interruption to Service. During the year two interruptions in service occurred exceeding a few seconds, one on the morning of the 15th June, the north line failing while the south line was under repair; the second line failed at 1.2.44 a.m. and was restored at 4.58 a.m. The second breakdown was on the morning of the 6th February, when, owing to line trouble, the emergency gear on the turbines came into operation and shut down the station. The failure took place at 12.3 a.m., and, owing partly to the time at which it occurred and partly to the fact that a very thorough investigation of the cause of shut-down was essential before again putting the plant into operation, supply was not resumed until 2.40 a.m. ; thus a total interruption of two hours and forty minutes ensued, but fortunately at a period of light load and therefore with a minimum of inconvenience to consumers. Water-storage. After an abnormally dry year, and with the increased demand for power, the anticipated recovery in the lake-level in the spring of the year did not take place. The level fell at the beginning of March to 1,658-8, the lowest point so far reached, and only by concentrating on the lowering of the lip of rock at the entrance to the intake was the supply maintained. In the meantime the work of cutting the race and building of intake for the Harper diversion had been energetically pursued, and on the 3rd March, 192], a small temporary diversion of the river was made. The immediate result was most gratifying in that the downward trend in the lake-level was stopped, and there is every indication that the position will be secure until such time as the. permanent diversion of the river is completed. A graph showing the effect of the diversion on the lake-level is published herewith.

Selling-rates. The selling-rates for supply have been slightly modified, and all additional consumers and those whose agreements expire are now placed on the standard rates. Industrial Developments. The shortage of power has restricted new industrial developments, and neither Messrs. Kemp-thorne-Prosser's new chemical works in Hornby nor the Kaiapoi Woollen Company's works in Woolston are as yet receiving power. Messrs. Waddell's steel-furnace has been operating fairly continuously during the last few months of the year, but in the meantime is confined to night supply only.

Table H. — Total Connected Load in Kilowatts at 31st March, 1921, Lake Coleridge.

Local Electric-supply Systems. Apart from the two main Government supply systems there are fifty-five power-supply stations in the Dominion, as detailed in Tables I and J herewith. Seven additional licenses for local electricsupply plants (Fairlie, Kaikoura, Murchison, Whakatane, Motueka, Havelock North and Opunake) have been issued during the year, and construction is in hand, but, owing mainly to the financial stringency, no additional stations nave been completed during the year under review, and very slight additions have been made to the total plant capacity. A license has also been issued to Te Puke Town Board for taking bulk supply from the Tauranga Borough Council. The additional power proposed in the seven main installations of the Dominion, as detailed in last year's report, amounts to 45,000 h.p., at an estimated cost of £1,582,000. These are all well in hand, but, owing to the delays in the delivery of material and to the financial stringency, none of these extensions have yet been completed. The total maximum output has increased during the year from 30,716 kw. to 42,157 kw. The total installed capacity in the fifty-seven power-stations amounts to 49,630 kw. of main plant and 5,831 kw. of subsidiary or standby plant, made up as follows :—

The total of the maximum loads was 42,157 kw,, as compared with a total installed main capacity (apart from special auxiliary plants) of 49,630 kw., showing a margin of 7,473 kw., or 15 per cent, of spare plant, and this in spite of the fact that many of the stations have been seriously overloaded— pointing again very strongly to the advantage of interconnecting all available power sources, thus increasing the working-capacity of the system as a whole by reducing the margin of spare plant required and enabling every station connected to the system to come to the assistance of any other that is in trouble. Definite plans are in hand for the interconnecting of the Thames and Te Aroha plants with Horahora, and Akaroa with Lake Coleridge. Several other proposals for interconnection have been made, including Lake Coleridge and Waipori Falls, and the interconnection of the whole of the six Taranaki power-stations and of the three Bay of Plenty stations. Pending the completion of the large Government hydro-electric stations this policy of interconnection of the existing smaller plants will be of the utmost assistance in enabling the present small plants to carry on to the best effect until the larger sources of power are in operation. With regard to the seventy-four authorities operating the fifty-seven stations and seventeen distribution systems taking bulk supply from a larger power authority, these are distributed as follows :—

The total number of consumers at the end of the yea.r was 73,151, as compared with 58,449 at the beginning of the year, an increase of 25-2 per cent. The total length of reticulation-line in the Dominion is about 2,260 route-miles, and of trans mission-lines about 360 route-miles, totalling 2,620 route-miles. The average number of consumers per mile of reticulation is thus 32-3. The population, according to the 1921 census, of the districts already supplied amounts to 684,175 out of a total population of the Dominion of 1,218,270 ; but the population already supplied consists almost entirely of residents in the cities and boroughs, and the important function of supply ing the farming and country consumers is only now being taken up by the Electric-power Boards. The units generated during the year in the fifty-seven power plants amounted to 149,476,379, of which 124,446,459 were sold or accounted for to 73,151 consumers, and 25,029,920 were lost or unaccounted-for, showing an overall efficiency of distribution amounting to 16-7 per cent. The units sold per consumer, after deducting 33,278,932 units for tramway supply, were 1,246, and the units sold per head of population supplied were 133. The maximum demand (42,157 kw.) was 0-576 kw. per consumer, or 0-061 kw. per head of population supplied. The aggregate of eight tramway peak loads was 13,240 kw. and is included in the total of 42,157 kw. The present demand in Canterbury is 0-063 kw. (0-084 h.p.) per head, and in Dunedin 0-082 kw. (0-109 h.p.) per head. These figures are important owing to their bearing on the estimate of the future demand irom the large Government schemes under construction which is taken as o'ls kw. (i.e., 0 - 2 h.p.) per head of population— practically double the present supply per head in Canterbury and Dunedin. Although the industry, as a whole, yielded a net profit of £68,106 for the year after paying interest and sinking fund of £233,078, it will be noted from Table G herewith that out of the seventy four systems thirty worked at a loss. This is due mainly to the increasing costs of supply, and the difficulty in raising the charges to keep pace with these increases. Several applications were received during the year for increases in the maximum charges permitted by license, and in most cases were justified by the circumstances. In other cases, such as Auckland and Wellington, the increased cost of coal has necessitated increasing the charges, though still below the limits allowed by the license. It is hoped that costs have already passed their maximum, and will shortly show a falling tendency, enabling those stations which have been operating at a loss to recover their financial position, and with increasing output and improved economies to offer a reduction in charges to the consumers. With regard to the standardization of the systems of supply there has been practically no change during the year, but several of the older installations are preparing to change over to the standard three-phase 50-cycle system, which now includes 29,980 kw., or 54-3 per cent., of the generating plant installed in the Dominion (55,461 kw.). The annual load-factor of the whole output of the fifty-seven stations for the year, amounting to 149,476,379 units, with a maximum demand of 42,157 kw., has been 40-4 per cent. This is the average

result of all classes of generating plant. The load-factor is, of course, higher for water-power plants than for fuel plants, the figures for each type being as follows : —

In order to determine exactly the day load-curve — i.e., the distribution of the load over the various hours of the day—arrangements were made with the engineers of the fifteen largest powerstations, comprising 78 per cent, of the plant capacity of the Dominion, to take half-hourly observations of the loading on the 30th September, 1920, and the 30th June, 1921, as representing typical equinoctial and midwinter loading. These figures were very courteously supplied, and the total results have been plotted in the graph herewith. These curves show a very large difference between the summer and winter demand, although the normal growth in the demand over a period of nine months is also

taken into account. The curves show an increase in demand of about 4,000 kw. in the daytime and 8,500 kw. in the afternoon between 4 and 5 p.m. The relative shapes of the summer and winter curves are also important, the winter curves showing a peak between 4 and 5 p.m., and the summer curve between 8 and 9 a.m. It is rather surprising to note that even under present New Zealand conditions the all - day demand is so high, and with the large development of hydro-electric power and the consequent increasing industrial and cooking load the evening demand will become a still smaller proportion of the daily peak load. The two curves show the following results : —

It will be noted that the fuel plants with their higher average charge per unit show a distinct evening lighting peak load, and consequently a much lower daily load-factor (503 per cent.), than the water-power plants (72-7 per cent.), for which the peak load occurs in the daytime. Coming now to the general technical and financial results of the operation of the whole of the electric-supply systems of the Dominion analysed according to the source of supply, they give the following results : —

Inspections. During the year the following electric-supply systems were inspected, viz. : Patea, Waverley, Feilding, Bull's, Hawera, Stratford, Waitara, New Plymouth, Kaponga, Inglewood, Eketahuna, Pahiatua, Hastings, Napier, Reofton, Picton, Tai Tapu, Brightwater, Hokitika, Westport Company (Denniston), Westport-Stockton Company (Ngakawau), Bluff, Mataura, Winton, Gore, Oamaru, Timaru, and Ashburton. These were done as opportunity offered, and represent less than half the number of systems. Hitherto the duties of Inspecting Electrical Engineer have been performed by one officer, but with the increase in the amount of inspection work it has not been possible to get round all the systems during the year as has previously been done. With the inception of the Electric-power Boards, together with new supply-stations, the demands on the Inspecting Electrical Engineer are rapidly increasing, and proposals are being made for the delegation of some of the routine inspections to District Engineers, but still subject to control from this office. In order to reimburse the Department for the expenses in connection with inspection work a schedule of fees has been drawn up and is now in force.

Ki,u<trio-power Districts. The organization of electric-power districts under the Electric Power Boards Act of 1918 has proceeded vigorously during the year, although the number of power districts actually constituted has only increased from the ten previously recorded to fourteen, as set out herewith, Westland, Reefton, Dannevirke, and Opunake Power Districts having been formed. The total area covered by these fourteen districts is 18,869 square miles, being 18-1 per cent, of the total area of the Dominion, and the total population included is 158,157, being 12-95 per cent, of the population of the Dominion. Nine of the Boards have laid out their reticulation systems and submitted the necessary loans to the ratepayers for approval. Of these, one (Southland) includes a generating-station at Lake Monowai, and the other eight provide for taking power in bulk from the Public Works Department. The total amount of the loans authorized by the latcpayers of these nine districts amounts to £2,950,000. This is £21-6 per head of population concerned, and 6"7 per cent, of the unimproved rateable value (£39,116,812).

In addition to the Power Boards that have already been constituted, petitions are in course of circulation in the following districts : — Population. Area in Square Miles.

The provisions of the Electric Power Boards Act are thus being widely adopted throughout the Dominion. The boundaries of the proposed districts generally follow fairly close on those suggested in the last annual statement, but in several cases, particularly Auckland, Rangitikei-Wanganui, Taranaki, and Bay of Plenty, larger districts have proved advisable. Some of the districts already constituted are proving too small for the greatest economy in construction and operation, and combinations of these districts are desirable. In order to enable each Power Board to deal effectively with its back-country reticulation it has been found essential that it should have greater financial strength than the smaller Boards can command, and should be so large that it is unlikely to be swayed by local or parochial influences, though in a few cases of entire isolation, such as Queenstown, Taupo, Murchison, and Reefton, local Power Boards may be advisable. The principles on which the boundaries of the electric-power districts should be determined are not set out in the Act, but under section 3 the responsibility of deciding whether the boundaries proposed by the Local Committee are advisable or otherwise is cast on the Government, and this responsibility has been accepted in several cases by proposing amendment to the draft petitions before they are issued for signature. It is essential that such draft petitions should be submitted for approval in each case, as great difficulty has arisen in some cases owing to petitions being signed

for districts with unsuitable boundaries. In order to decide the Correct areas into which the Dominion should be divided for the purposes of the Act the following considerations should be taken into account: — (a.) The district must be large enough to have financial strength. For this purpose the demand should be at least 1,000 h.p., yielding a revenue to the Board of about £15,000 per annum and involving a population of about five thousand persons. This is a minimum size in cases in which geographical and other considerations do not permit of a larger district. In the general case, where possible, the population should be over twenty thousand, requiring over 4,000 horse-power and yielding a revenue of over £50,000 per annum ; and in special cases, including large cities, the size may be even two or three times greater than this with advantage. (b.) The district should include both town and country areas, but should have a distinct community of commercial and industrial interests. The country districts should be included with the town through which their produce is sold and their necessities purchased, and the whole of the back country trading through any one centre should be included with that centre. The boundaries must be designed to foster and encourage this natural community of trading interests. (c.) The district must be designed to give convenient road access for the distribution-lines, to ensure both economical construction and for effective patrol and maintenance. From this point of view the boundaries will consist, whenever possible, of mountainranges or large impassable rivers. (d.) The district must be designed to utilize as far as possible the points of distribution selected as most convenient for the purposes of the main Government transmissionsystem, and as far as possible the whole output of each of the main Government substations should be taken over by a single Power Board. This will not always be possible owing to the geographical configuration of the district, but should generally be complied with. («.) For rating and statistical purposes it will be advisable, as far as possible, to utilize existing county boundaries whenever they conform approximately to the above considerations. In the light of these considerations and of the experience gained so far, a number of the districts are now combining, and the attached table gives the districts proposed as a result, the population having been revised in accordance with the 1921 census : — List or Suggested Electric-power Districts. This allocation of suggested power districts represents what is considered to be the minimum areas for the most economical distribution, but in some instances, where community of interest is proved, the merging of adjacent areas to form a larger district will be approved. The subdivision of these proposed areas should bo avoided wherever possible unless substantial reasons are advanced
