bread is used. Durum, poulard, and Polish are used only 

 in a limited way in the making of bread, their greatest 

 usefulness being found in the manufacture of macaroni, 

 spaghetti, and other similar products. Emmer, spelt, 

 and einkorn are used in the feeding of live stock. Bread 

 wheats and those used in the making of macaroni may be 

 classed in several different ways. They may be divided 

 into two groups based upon the time of sowing, viz. 

 spring or winter wheats; based on the structure of the 

 kernel, viz. hard and soft; according to their uses, 

 viz* bread and macaroni; according to the color of the 

 grain, viz. red and white. Most often the classification 

 used is a combination. Thus spring wheat may be either 

 white or red, hard or soft, used either for bread or maca- 

 roni. 



THE USES OF WHEAT 



100. General uses. — The wheat crop is perhaps 

 more closely related to the welfare of mankind than is 

 any other crop. Almost all of the grain from the world's 

 wheat crop is used in the manufacture of flour for human 

 consumption, although a small amount of it is used 

 in the feeding of animals, the grain for this purpose being 

 principally that of poor quality and unsuitable to use in 

 the making of flour. In the milling of wheat flour, several 

 by-products result which are important live stock feeds, 

 and the straw also is used for the feeding and bedding of 

 animals. In its chemical composition and palatability, 

 the wheat grain ranks high as a feed for live stock, but the 

 high price per bushel which it commands for flour-making 

 purposes prevents, excepting in years of heavy yield, 

 its use as feed for domestic animals. The milling of wheat, 

 the grades and kinds of flour, and the uses of the by-
