THE RACES OF CORN 



We find in New England cornfields, sweet corn

 States, chiefly the yellow dents; in the South, white 

 dent varieties. Dent corns have their starchy 

 content extended to the top of the grain, and 

 shrinking at maturity, thus forming the dent, or 

 depression. Flint corn is not so, for the starchy 

 centre is overlaid with thq layer of hard, horny 

 material that does not shrink. 



Pop corn is small, and its grains explode into a
