20. Rising Mains.—In view of Messrs. TANGYE's comments on the size of the Delivery Pipe I propose to make the rising main 18 inches in diameter and, with a view to the future duplicating of this main, to lay the temporary suction main required in connection with the scheme now submitted with pipes of the same diameter.
I
21. I note the procedure laid down in paragraph 9 of your letter, with which am quite in accord and which is as follows:-
(a.) Two engines on order will be despatched when ready.
(b.) The steam and feed piping will be settled on receipt of this letter
and will be sent out when complete.
This should be in accordance with the arrangement of engines and boilers shown on tracing B, the boilers being so connected as to be interchangeable with future boilers. The exhaust pipes may be arranged as found most convenient (ride Messrs. TANGYE'S letter of 24th July, 1903).
(c) Full particulars of the trial works carried out and of the works now
proposed are contained in this letter and its enclosures.
22. The only other points to which I have to refer are some mentioned in Messrs. TANGYE's letter to you of the 24th July last.
23. I have fixed the width of the engine-house at 30 feet which should give ample room for the future 2-million gallons plant, thus enabling one traveller to serve for all the engines. I note that a length of 82 feet will be required for the plant on order and one additional engine of 2-million gallons capacity.
24. The boiler flues should be laid out to suit the arrangement shown on tracing B, and I shall be glad to receive full particulars of these when settled.
25. The suction pipe might be kept inside the engine-room and should of course be of a larger size with branches to the various sets of pumps, but the delivery pipe should be kept outside as it will be under a considerable head. This arrangement is indicated on tracing B for your consideration and, if it meets with your approval, the specials for it should be ordered without further reference to me.
26. I have perused with interest your report to the Crown Agents dated 12th August on the question of contamination of the impounded water by salt saturation should the lower dam be constructed as intended in the tidal portion of the bay. The report is of much value and interest and I am gratified to find that it endorses my own opinion on the matter.
27. Whenever I am in a position to do so, I will submit for your approval the low-level portion of the scheme, but you will, I think, agree, in view of the inform- ation I am now able to lay before you, that it is desirable to proceed at once with the construction of the dam I have recommended.--I have, &c.,
