PRODUCTION (BUSHELS) OF GRAIN OF KAFIR AND MILO FOR THE FIVE 

 LEADING STATES IN 1909 



1. Texas 5,860,444 4. California 938,049 



2. Kansas 5,115,415 5. New Mexico .... 543,350

The production of rice has shifted in recent years 

 from the South Atlantic coast to Louisiana and Texas, 

 where upland rice is now grown. Over nine-tenths of 

 the acreage of this crop is now in the two last- 

 mentioned states:

STARCH 



10. All the grains mentioned may be used for the pro- 

 duction of starch and alcohol. From the commercial 

 standpoint, the chief starch-producing plants of the I/ 

 world are corn, wheat, rice, potatoes and arrow-root. I 

 Wheat is usually too valuable a human food to be used 

 for any other purpose. Corn is the chief source of starch \/ 

 in the United States, although the other grains may be* 

 used when available. In the manufacture of starch from 

 corn, the grain is soaked but not allowed to ferment. The 

 softened kernels are then ground in water and the starch 

 purified. A bushel of corn will yield twenty-eight pounds 

 of starch and thirteen pounds of refuse available as 

 cattle food. In Europe the potato is the chief source of 

 starch.
