spaces can easily be seen. From the fact that the kernel 

 is the unit of the grain on the cob, it is at once evident 

 that it is extremely important to secure the kernel of 

 the proper shape, proportionate to its size, and develop 

 uniform kernels of this type on the entire ear. The 

 desirable type of kernel for every type, as in the case of 

 the breed characteristics, is a matter of experience which 

 must be gained through familiarity with all types. 



In judging shape of kernel, count the number of wedge- 

 shaped kernels in the ten pairs that have been taken out 

 for study of uniformity. Mark according to the proportion 

 of well shaped kernels. For instance, if there are eight 

 pairs of properly shaped kernels, mark the exhibit four 

 points on shape of kernels. 



LENGTH OF EARS 



The deficiency and excess in length of aH ears not con- 

 forming to the standard for the variety should be added 

 together, and for every inch thus obtained a cut of .5 point 

 should be made. In determining length measure from the 

 extreme tip to the extreme butt. In measuring length it 

 is most convenient to hold a foot ruler in both hands, one 

 end even with the butt and the other end over the tip. As 

 the ruler is drawn from ear to ear in the sample, it is an 

 easy matter to keep in mind the amount each ear is shorter 

 or longer than standard. Add the excess and deficiency 

 together. 



CIRCUMFERENCE OF EARS 



The excess and deficiency of all ears not conforming to 

 variety standard should be added together, and for every 

 inch thus obtained a cut of .25 point should be made. In 

 measuring circumference use a tape line. Measure the 

 circumference at about one-third the distance from the 

 butt to the tip of the ear. In order to do this conveniently
