WHEAT

stretching north and south entirely across the United 

 States into Canada, is a very large area, in which wheat is 

 grown either in very small scattered patches by irrigation 

 or in a few special localities where, because of the nature 

 of the soil, " dry-farming " is possible, even with the very 

 low rainfall. Where irrigation is practiced, the wheat is

very soft, usually white, and starchy. Where Turkey or 

 Kharkov wheat is employed under so called " dry- 

 farming " in the central and northern portions, the wheat 

 is much harder and more glutinous, but not so much so 

 as when grown on the Great Plains. The influence of 

 the Chinook winds permits the growing of these winter 

 wheats as far north as Montana, and even in southern 

 Alberta (Fig. 24).
