The cost of installing irrigation equipment on an acre of ground 
usually les between $100 and $150, according to the price of pipe 
and a man’s ability to pick up bargains and to utilize material that 
is lying around. These figures do not include the water supply, 
which is, of course, very difficult to estimate on account of the 
wide variation in conditions. 
IRRIGATION BY UNDERGROUND PIPES 
| Other methods of irrigation are practiced in various sections 
of the country. About Boston a system of underground pipes is 
frequently installed which, with fifty feet of hose, will reach all 
parts of the garden. It costs about $65 to equip the first acre and 
roughly $50 per acre thereafter. An inch of water (27,152 gals.) 
may be applied to an acre of ground with an inch and a quarter 
hose by a single man in five or six hours. This method is not very 
generally favored on account of the labor and the cost of maintain- 
ing hose, and on account of the distribution of plants and danger 
of injuring the physical condition of the soil. 
SUB-IRRIGATION 
Where the sub-soil is impervious, or where, as in the case of the 
muck lands, a high outlet maintains the water table relatively near 
the surface, it is possible to water by sub-irrigation. On the muck 
lands this is accomplished by merely blocking the outlet in such 
a way as to bring the water up a little nearer to the surface. The 
soil is well saturated, the outlet is again opened and the surplus 
water allowed to drain off. Of course, this will not work unless 
there is a small stream flowing into the swamp, though such is 
frequently the case. At Sanford, Florida, sub-irrigation is prac- 
ticed by means of a system of ditching almost like that used for 
drainage. In fact, the same lines may be used for both irrigation 
and drainage. In this district the water supply is from artesian 
wells. Surface irrigation is utilized to some extent in the East.
