On Water Supplies suited to 
cated would be considerable. Thus, an iron storage-tank with 
cover and cock, would cost 40Z. if placed aboveground. A 
cistern underground of the same capacity, with its pump, would 
cost 211., and the filter and service-tank would come to about 3^. 
I am sure, however, that many landowners, who wish to see their 
labourers well provided, would not hesitate to incur the expense 
necessary to give the priceless boon of a fair supply of good 
water, and would moreover see that the appliances provided at 
so much cost were kept in proper order. The filters, for example, 
will require cleaning from time to time — that is, the top layer of 
sand, about 1 inch thick, will have to be removed, washed, and 
replaced ; a little fresh sand will have to be added now and 
then to make up for waste. This operation can be performed 
in half-an-hour, but it is, nevertheless, very likely to be 
neglected. 
For the supply of homesteads similar arrangements can be 
made. The whole of the eaves-gutters should be connected by 
down pipes to a common main-pipe, which would lead to the 
storage tank. It is best to connect the eaves-gutters at about 
their own level as much as possible, so as to avoid underground 
pipes, which are apt to get choked ; and the gutters should be 
of ample size, in order that no storm-water may be wasted by 
overflow. The underground pipes should be laid as much as 
possible in straight lines, converging to small catch-pits, which 
could readily be opened and the pipes cleaned by the insertion 
of long rods, should any stoppage occur. 
In vol. XV. (1879) of the 'Journal' will be found the plans 
and descriptions of a homestead for a dairy-farm of 400 acres. 
The available roof-area of all the buildings is 35,487 square 
feet, hence a 24-inch (2 feet) rainfall would yield 
35,487 sq. feet x 2 feet x 6*2 galls. _j^206 galls 
365 days 
per day, and the storage capacity should be at least 
35,487 sq. feet X 2 feet ^ ^^^^^9 cubic feet.

According to Dr. Parkes, a horse requires a minimum supply 
of 6 gallons per day ; cattle, 5 gallons ; swine, 1 gallon ; and 
men, say 6 gallons. 
The requirements of the homestead may be thus calculated : 
11 Horses at 6 gallons per head = 66 gallons per day. 
170 Cattle „ 5 „ „ = 850 „ „ 
150 Swine „ 1 „ „ = 150 „ „ 
Say 8 Men „ 6 „ „ = 48 „ „
