Wainihinihi Water-race. As the season was exceptionally wet there was an excellent supply of water from this race during the year. During the month of July a slip occurred on the side of the mountain immediately above the race, which broke down three sets of timber and filled up the ditch, but repair's were promptly effected by the men working on the Waimea Branch Race, and the water was only off for about four days. Waimea-Kumara Water-races. The following is a summary of the revenue and expenditure of these races for the year ended the 31st March, 1915: Sales of wafer, £2,372 ss. lid.; cash received, £2,098 13s. 3d.; expenditure, £2,228 17s. 7d. ; approximate value of gold obtained, £20,268 6s. ; average number of miners employed, 77-83. Although the sales of water showed an increase of £270 os. 4d. on the previous year, the cash received only showed an increase of £4 1 2s. Lod., but a considerable.percentage of the debit balances outstanding on the 31st March should be recovered during the ensuing year. In addition to the above sales, authorized free water to the value of £360 18s. 4d. was supplied to parties opening up new claims. The total expenditure on the combined races was £2,228 175., as against £1,803 7s. 4d. for tho previous year, an increase of £425 10s. 3d. This increase was principally caused by repairs to the Waimea Water-race at Fox's and the long-drive tunnel at Maori Point, and the maintenance of the Erin-go-Bragh Race for twelve months as against nine months of the previous year. Comparing the sales of water with the expenditure, the combined races show a profit of £1.43 Bs. 4d. for the year.

The average number of men employed Was 26-6. Prom the Ist April until the J Ith July, when hard frost compelled most of the claims to close down, there was a plentiful supply of water. A thaw set in on the 24th July, and most of the claims were again at work on the 27th. From then until the Bth October, when the water was turned out for cleaning and repairs, there was a full supply of Water. On the 14th September, the Weather being favourable, and there being a good supply of Water on the lower sections of the race, I started with all the available men to clean and repair the race from Hill's Creek upwards, and finished on the Bth October, when the water was turned out to clean and repair the lower sections. This work was completed and the Water on again on the 22nd October. Prom this date until the Eweburn reservoir ran out, on the 17th January, there was a full supply of water. Tin; weather at this time became very dry, and until rain set in on the 3rd March there was just sufficient water to supply the claims about half-time. At the time of cleaning the race, and owing to the increased demand for water in Spec Cully, I found it necessary to give about five miles of the main race an extra good trimming and cleaning. I also lowered the bottom of the race from the intake of Wedderburn siphon to the head of Store Gully.
