be well carried out and the kernels conform closely to those 

 in the main body of the ear in shape and size. The propor- 

 tion to tip covered or filled must be considered. Long pointed 

 tips as well as enlarged or double tips are objectionable. 



6. Butts. The rows of kernels (Fig. 69) should extend in 

 regular order over the butt, leaving a deep depression when 

 the stem is removed. Opened and swelled butts, depressed 

 and flat butts with flattened glazed kernels are objectionable. 



7. Kernels. (a) The kernels should be uniform in size 

 and shape, making it possible so to grade the corn as to secure

even dropping by the planting machine. This is essential to 



securing a good stand. Not only should the kernels be uni- 

 form on the individual ear but they should be uniform with 

 all the ears selected. (6) The shape of kernels should be such 

 that their edges touch from tip to crown (see Fig. 67, 3). The 

 tip portion of the kernel is rich hi protein and oil, and hence 

 of high feeding value. Kernels with large germs insure strong, 

 vigorous growth as well as richness in quality of kernel. Germs 

 should be large, showing strength and high feeding value 

 (Figs. 71, 72).
