CHAPTER XIV. 

 SMALL GRAINS. 



Wheat. — ^Wheat is probably the oldest grain used by 

 man. It is more extensively grown and used than any other 

 human food except perhaps rice. When flour is made from 

 it the by-products are now extensively used to feed animals. 

 In America the newer lands in some portions of the West 

 produce the largest crops of wheat, but the grain is grown 

 somewhat in all sections. 



Types of Wheat. — As a general rule, the drier regions of 

 the middle West produce hard winter wheat or hard spring 

 wheat, best for flour; the humid climates produce soft wheats.
