264 IRRIGATION PRACTICE 



about 29 acre-inches of water were applied throughout 

 the season to the field, including the rainfall ; the evapora- 

 tion was about 16 inches, leaving 13 inches that were 

 actually used by the plant. This is not greatly different 

 from the quantity of water actually supplied, by irriga- 

 tion, to other cereals. 



The rice industry is very old in the United States. 

 For many years it had languished, but of recent years 

 has appeared to show signs of new growth. It is probable 

 that the study of varieties of rice suitable for growth on 

 the great irrigated areas of the country, where less water 

 must be used, may develop another highly profitable 

 branch of industry for the irrigated region. (Fig. 62.)
