Kil, T. W. KEELE. 
I have not wearied you by quoting so fully from his paper, 
instead of condensing what I am sure you will all admit is 
an exceedingly valuable record. 
Royal Commission of 1867.—The Royal Commission of 
1867 consisted of the following gentlemen, viz.:—Professor 
J. Smith, M.p., Sydney University; Mr. E. O. Moriarty, 
M. Inst. C.E., Hngineer-in-Chief for Harbours and Rivers; Mr. 
P. KF. Adams, Surveyor-General; Mr. F. H. Grundy, C.£., 
and Mr. Thomas Woore. Mr. W. OC. Bennett, M. inst. c.n, 
Commissioner and Engineer for Roads and Bridges, was 
added to the Commission the following year. 
In considering the question submitted to them, the 
Commissioners had to determine— 
1.—The population to be supplied. 
2.—The condition and prospects of the present scheme. 
3.—New sources of supply. 
They found that in 1826 the population was put down at 
10,000, in 1836 at 20,000, so that it had doubled in the 
short space of ten years. Intwelve or thirteen years more 
it had doubled again, but in consequence of the attractive 
force of gold, the next doubling was effected in six or 
seven years. After that the rate fell, and although 
thirteen years had elapsed since the population reached 
about 80,000, it had made only half as much more up to 
the time they were considering it, viz.:—1867. For the 
previous few years it had been increasing at the rate of 
over 4° per annum. 
Aiter careful consideration, they deemed it to be their 
duty to show how a population of, say a quarter of a 
million, could be liberally supplied, and decided upon 12 
million gallons per day, being at the rate of 48 gallons per 
head per day, and that the scheme should be capable of 
expansion to at least double that amount.
