330 DRY-FARMING 
this work with a feeling of greater security. Of 
course, it is true that the dry years affect the flow of 
water in the canals and that the frequent breaking of 
dams and canal walls leaves the farmer helpless in the 
face of the blistering heat. Yet, all in all, a greater 
feeling of security is possessed by the irrigation- 
farmer than by the dry-farmer. 
Most important, however, are the temperamental 
differences in men which make some desirous of giving 
themselves to the cultivation of a small area of irri- 
gated land under intensive conditions and others to 
dry-farming under extensive conditions. In fact, it 
is being observed in the arid region that men, because 
of their temperamental differences, are gradually sep- 
arating into the two classes of irrigation-farmers and 
dry-farmers. The dry-farms of necessity cover much 
larger areas than the irrigated farms. The land is 
cheaper and the crops are smaller. The methods to 
be applied are those of extensive farming. The prof- 
its on the investment also appear to be somewhat 
larger. The very necessity of pitting intellect against 
the fierceness of the drouth appears to have attracted 
many men to the dry-farms. Gradually, the cer- 
tainty of producing crops on dry-farms from season 
to season is becoming established, and the essential 
difference between the two kinds of farming in the 
arid districts will then be the difference between 
intensive and extensive methods of culture. Men 
will be attracted to one or other of these systems
