10 DRY-FARMING 



season ; the regulation of the amount of water drawn 

 from the soil by plants ; the choice of crops suitable 

 for growth under arid conditions; the apphcation 

 of suitable crop treatments, and the disposal of drj"- 

 farm products, based upon the superior composition 

 of plants grown with small amounts of water. 

 Around these fundamental problems cluster a host 

 of minor, though also important, problems. Wlien 

 the methods of dry-farming are understood and 

 practiced, the practice is always successful; but 

 it requires more intelligence, more implicit obedience 

 to nature's laws, and greater vigilance, than farming 

 in countries of abundant rainfall. 



The chaptei-s that follow will deal almost wholly 

 with the problems above outlined as they present 

 themselves in the construction of a rational system 

 of farming without irrigation in countries of limited 

 rainfall.
