during the latter part of 1882, was of some assistance, but 
did not go very far towards replenishing the sand beds at 
Botany, which had to withstand an exhaustive drain upon 
them for the previous three years, so that by January, 
1884, fears were again entertained of a shortage of water, 
and an appeal was made by the City Hngineer for economy 
in the use of it, as at the rate of consumption, then about. 
7 million gallons per day, the stock of water in the Botany 
dams would last only three months. 
As it would be some years still before water through 
the permanent works could be delivered into Sydney, 
another movement was made by the Kenny Hill supporters, 
to bring in the waters as an auxiliary to the Prospect 
scheme, at a cost of £225,000, the scheme being modified 
by the exclusion of the storage reservoir, and the substitu- 
tion of wrought for cast iron in the supply pipes, one only 
to be laid. The service reservoir to be increased in capacity —

Woollahra and Waverley. It was claimed that the scheme 
would provide sevenfold the delivery to Paddington, and 
over double the duty above it, than that estimated by Mr. 
Clark, and would provide a moderate high pressure through- 
out the city and suburbs. The scheme, however, was not 
entertained by the authorities, and the agitation simmered 
down again, the works being pushed on with all the 
expedition possible. 
Nepean and Cataract Tunnels completed, 1885.—The 
Nepean tunnel was pierced through on 16th August, 1884, 
and the Cataract tunnel on 29th January, 1885, both 
tunnels being ready to deliver water about May 1885. By 
this time public attention—owing to the continuance of
