PARTITION OF INGREDIENTS OF MAIZE 



From a bushel (56 pounds) of maize there are obtained about 38 

 pounds of hominy, or grits, and about 18 pounds of by-products, con- 

 sisting of — 



(a) The hulls of the grains, together with the tips, derived from the 



cob about 2 pounds. 



(b) The germs about 9 pounds. 



(c) The starch immediately surrounding the germ and tip, which is 



necessarily scoured off in the various processes of grinding and 

 screening about 7 pounds 



These three products ground together constitute hominy feed. The 

 percentages of the various products, therefore, are approximately —

Partial analyses of samples of the hulls and tips, the germs, and the 

 hominy were also made, with the results shown in Table IV.
