18 INDIAN CORN CULTURE, 



between them clearly seen by splitting the 

 kernels. In Fig. 3 the shaded parts of kernel 

 above the base represent hard or corneous mat- 

 ter ; the white parts starchy matter. 



Pop corn. — The substance of the center ker- 

 nel is hard and flinty (corneous) all through, 

 excepting at the germ end, no white, soft 

 starchy substance being present. See a in 

 Fig. 3. 



Flint corn. — The corneous matter surrounds 

 the sides and top of the kernel, so that it is en- 

 closed in a hard, flinty coat, with soft starchy 

 substance in the central part. The kernel is 

 usually about as broad as long, and rounding 

 and smooth over the top. Flint corn is some- 

 what smaller than dent, and is best suited to 

 New England- and the northern line of corn 

 growing. See h in Fig. 3. 



Dent corn. — The sides of the kernels consist 

 of corneous matter with the central part filled 

 with soft material, even to the dented or con- 

 tracted rough top. This contraction is due to 

 shrinking of the softer part of the kernel in 

 ripening. The kernel in many varieties is 

 slender or wedge form. Nearly all the corn 

 grown in the great corn belt of the Central 

 West belongs to this race. See c in Fig. 3. 

 -^; Sweet corn. — The kernels consist of translu- 

 cent, horny material, which contain consider- 

 able sugar (glucose) instead of starch. The
