not so. Even in America the farmers of 

 Utah have been raising crops on their 

 dry -lands with a rainfall of less than 15 

 inches for over half a century. More than

 since the dawn of civilization in Mesopo- 

 tamia in Egypt, and in northwestern 

 India. And, as Hilgard has pointed out, 

 the great depth of soil in arid regions as 

 compared with that of humid climates
