368 Irrigation and Drainage 



The object of placing the reservoir in the center 

 of the area to be controlled is to utilize the seepage 

 from the reservoir to hold up the ground water to 

 the desired level more readily. A 12 -foot steel mill 

 should readily handle 3 to 5 acres if the water 

 supply is abundant, the ground not too porous, and 

 the lift not more than 20 feet. But if by such an 

 arrangement as this a farmer could have only two 

 acres or even one acre of cranberries under complete 

 control as regards frost and insects, as an adjunct to 

 his general farming, it would net him a handsome 

 profit which would supplement in an important way 

 his yearly income. 



It would, of course, be necessary to be able to 

 drain the area quickly after flooding, and if facilities 

 are not the best for this, it would be possible to so 

 arrange the pump that the water could be thrown 

 back into the reservoir again, and this could readily 

 be done for small areas where an engine was used 

 instead of a windmill for power. 



IRRIGATION OP RICE FIELDS 



In the irrigation of rice fields, where this is to 

 be done under the best conditions and where the 

 highest quality of rice is to be produced, it is a 

 matter of prime importance that the fields shall be 

 properly laid out, and that an abundant supply of 

 suitable water shall be under complete control. It 

 has been pointed out, in discussing the duty of water 

 in rice culture, that available statistics make the
