The cost of installing irrigation equipment on an acre of ground 

 usually lies 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 $05 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. Tn 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.
