It will be seen from the foregoing statement that the sales of water for the last year amounted to £129 10s., as against £126 16s. Id. for the previous year, while the cost of maintenance was £2 145., thus leaving a net profit of £126 16s. on the working of this water-race. The average number of miners employed in claims worked by the aid of this water-race was nine, and the approximate quantity of gold obtained by them was 140 oz., representing a value of £539. Deducting the value of sales of water from the value of the gold obtained, it leaves £489 3s. lid. as the earnings of the miners, which is equal to about £45 10s. per man per annum. The total cost of this waterrace was £1,036 16s. Argyle Eace. The Argyle Water-race, which supplies water to the Charleston field, is now managed by and under the control of the Buller County Council. Certain repairs and additions to the siphon being required, a subsidy amounting to £150 was given towards this work, which has been satisfactorily completed at a total cost of £350. Summary of Water-races. The following statement will show the profits and losses of working the different water-races constructed and maintained by the Government for the last twenty-one years, and also the collateral advantages derived by the utilisation of the water from these races : —

GOLD- AND SILVEE-MINING. In the conduct of operations prosecuted in search of gold and silver, steady perseverance has characterized the efforts of all the companies and persons who have entered on the industry as a field for legitimate investment. ■'■ Prospecting-works that were carried on throughout the goldfields in both Islands, and which did not realise encouraging results, have for the most part -been stopped, and only in those mines that are favourably situated, or those from which the returns have been satisfactory, have progressive and development works been vigorously prosecuted. It Is satisfactory to note that in most instances an increase in the yield has resulted from further development of quartz, alluvial, hydraulic sluicing, and dredging claims, on which improvements and additions have been made to the different plants and machinery required in the working of mines, and the recovery of the precious metals. Dividends to a considerable amount have been paid by quartz, hydraulic mining, and dredging companies, and there are evidences that the number of dividend-paying mines is on the increase.
