3. A moderately deep kernel. It is obvious that as between two ears 

 otherwise similar the one with the shallower kernels will have the less 

 grain. A good illustration of this may be had by finding two ears, one 

 with deep (Fig. 62, B,) and one with shallow kernels (Fig. 62, A,) but 

 with the same number of rows of kernels and with cobs of the same 



Fig. 61. — A, Cylindrical ear B, Tapering ear in which 

 several rows of kcriuis drop out between the butt and tip C, 

 Tapering ear in which the kernels become shallower towards

length, shelling them and weighing the grain. Note the difference in 

 the weight of grain. 



A deep kernel is almost always rough on the cap, and a shallow kernel 

 is smooth. Hence a desirable ear of seed corn will be somewhat rough 

 on the surface.
