354 IRRIGATION FARMING. 



fri<5lion, leakage, etc. , a twenty-two foot wheel would 

 raise 200 gallons from a well ten feet deep, which, if 

 kept running continuously at that speed, would irri- 

 gate, with the aid of a reservoir, about twenty-five 

 acres of land. 



Presuming that all the low lands along the valleys 

 can be irrigated by the use of canals, the question of 

 upland irrigation becomes one of great importance. 

 Admitting that the water-supply is sufficient for the 

 apparatus in use, we will suppose that a farmer desires 

 to irrigate five acres of land, with a possibility of ten, 

 from a one hundred foot well. To assure success for 

 the larger amount of land not less than a fourteen-foot 

 windmill should be purchased. A sixteen-foot would 

 be better. With either of these sizes, and a storage 

 reservoir, it will not be best to guarantee that over 

 eight acres can be irrigated, although there can be no 

 doubt that with the proper use of the water — keeping 

 the mills constantly in use, wetting down the land and 

 completely saturating the soil to the depth of six feet 

 or more, and carefully utilizing all sources of supply — 

 ten acres can be irrigated from this depth by mills of 

 either of these sizes ; but only by the best of manage- 

 ment, favorable conditions and great care in the hand- 

 ling and distribution of the water, will a fourteen-foot 

 mill irrigate the last amount given. In any event, a 

 storage reservoir at the well is quite essential, and by 

 its presence it is safe to say that all the way from fif- 

 teen to forty acres may be irrigated, by employing 

 various mills that may raise water at any distance 

 from ten to one hundred feet. 



It is best, in arranging to put in a windmill plant.
