 profitable farming upon non-irrigable 

 areas is absolutely dependent upon precipi-

 alternatives are cattle husbandry, travel, or 

 death. This thought is more fully exhibited 

 in Chapter IV. 



Fallowing every odd year with the possi- 

 ble aid of a cover crop assures crops even 

 years in many places too dry for yearly 

 crops by any method. The principle is 

 that intensive tillage during the odd 

 summer, plowing and continuous work- 

 ing thereafter, stores in the soil wet enough 

 to make a crop with minimum wet the even 

 year.
