 than 10 per cent, of the total area of the 

 arid West could be irrigated, and it is 

 certain that, because of physical ob- 

 stacles, it will never be possible to get 

 water to even this small percentage." 

 This statement clearly shows what a vast 

 tract of territory in America still re- 

 mains to be reclaimed by dry-farming. 



Now, although it would appear that a 

 great deal of the West is more or less 

 arid, it must not be forgotten that there 

 is a heavy fall of snow during the winter 

 over a very large area, which has a most 

 beneficial influence on the physical condi- 

 tion of the soil. Furthermore, the rain- 

 fall which in any given region may be 

 ample for certain drought-resisting 

 plants, will be quite inadequate for seeds 

 which have come from more humid covm- 

 tries, and which demand a much larger
