of an aggregate length of 2,206 lineal feet were used to cross five of the ravines, these consisted of two cast iron pipes 10 inches in diameter laid side by side. The discharging capacity of this conduit was 2,000,000 gallons a day until it reached syphon No. 4 where it was reduced to 1,700,000 gallons a day.

21. The work was completed in 1877, and the 10-inch main in the Pokfcolum Road removed at a total cost of $62,090.76, having been carried out under the supervision of Mr. W. Danby, C.E.

22. The completion of this work though providing for the delivery of Pokfoolum water above the level of the Robinson Road did not increase the quantity of the daily supply of water available during the dry season which practically remained the same as it was in 1873.

23. In a report dated 1st November, 1885, Mr. PRICE gives the following particulars regarding the water supply to the City of Victoria on his arrival in 1873. "In 1873 Victoria contained about 95,000 inhabitants, of which, however, excluding garrison and shipping, only 92,000 may be included in these calculations as water consumers, and the daily allowance was 5 gallons per head made up as follows:-

24. Mr. Price's Project. This condition of things in view of the increasing population of the City and the growing demands for water for trade purposes indicated only too clearly that some steps must be taken to increase the quantity of water available for distribution during the dry season. Consequently Mr. PRICE shortly after his arrival directed his attention to the subject and in a report dated the 1st November, 1873, submitted definite projects for the consideration of Government.

35. In this report Mr. PRICE enters at considerable length into the past history of the water question, and describes in detail the available sources of supply.

26. Projects are considered for obtaining an additional supply from the valleys of Pokfoolum, Aberdeen and Taitam, and the streams intercepted by the conduits that it would be necessary to construct for conveying the water from these valleys to the City.

27. The Pokfoolum project included the formation of a storage reservoir of 50,000,000 gallons capacity in the valley above the reservoir constructed in 1871 by the construction of a dam 350 feet long and 90 feet in height, and the formation of a further reservoir of 74,000,000 gallons capacity in the valley below the reservoir constructed in 1871 by the construction of a dam 250 feet long and 55 feet in height across the valley at the level of 457 feet above the sea.

28. The Aberdeen project included the formation of a storage reservoir of 213,000,000 gallons capacity by constructing a dam across the Aberdeen Valley above the present Paper Mills at a level of about 240 feet above the sea, the length of the proposed dam being 520 feet and its height 90 feet.

29. The Taitam project included the formation of a storage reservoir of 250,000,000 gallons capacity by the construction of a dam 400 feet in length and 90 feet in height across the Taitam Valley at a level of about 400 feet above the sea.

30. The total estimated cost of these projects and the minimum daily supply per head including 4.93 gallons per head derived from the existing Pokfoolum, Tai Hang and Wongneichong works estimated, on a rainfall of 50 inches per annum, a population of 92,000 and a drought of 240 days, is given as follows:—

31. The subject was referred to Sir ROBERT RAWLINSON, and the adoption of the Taitam project- with certain modifications was decided upon.

32. The following is a brief description of the project as carried out.
