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