II. Proportion of corn to cob 10 



The proportion of corn to cob is determined by weight. 

 Depth of kernel, size of the cob and maturity affect the pro- 

 portion.

RULES TO BE USED IN JUDGING 



1. Length of Ear — The deficiency and excess in length of all 

 ears not conforming to the standard shall be added together, and for 

 every inch thus obtained, a cut of one point shall be made. 



2. Circumference of Ear— The deficiency and excess in circum- 

 ference of all ears not conforming to the standard shall be added 

 together, and for every two inches thus obtained, a cut of one point 

 shall be made. Measure the circumference at one-third the distance 

 from the butt to the tip of the ear. 



3. Proportion of Corn to the Cob — Percent of corn should be 

 from 86 to 87. In determining the proportion of corn to cob weigh 

 and shell every alternate ear in the exhibit. Weigh the cobs and sub- 

 tract from the weight of the ears, giving the weight of the corn. 

 Divide the weight of the corn by the total weight of ears, which will 

 give the percent of corn. For each percent short of standard a cut 

 of one and one-half points shall be made. 



4. In judging corn, a red cob in white corn or a white cob in 

 yellow corn shall be cut at least two points. For one 09 two mixed 

 kernels a cut of one-fourth point, for four or more mixed kernels, a 

 cut of one-half point shall be made. Kernels missing from the ear 

 shall be counted mixed. Difference in shade or color, as light or dark 

 red, white or cream color, must be scored according to variety 

 characteristics. 



5. Exposed Tips — Where the full diameter of the cob is exposed, 

 a cut of one point shall be made and a proportionate cut as the cob 

 is less exposed. Regularity of the rows near the tip, and the size and 

 the shape of the kernels, must also be considered in scoring tips. 



6. Scoring Butts — If the kernels are uniform in size and extend 

 over the butt In regular order, give full marking. Small and com- 

 pressed or enlarged or open butts are objectionable, as are also those 

 with flat, smooth, short kernels, and must be cut according to the 

 judgment of the scorer. 



7. Each exhibit should consist of ten ears of corn. 



Color — The color should be either a pure yellow 

 with a red cob or a pure white with a white cob. A 

 white cob in a yellow sample or a red cob in a white 

 sample should bar the exhibit. It indicates very 

 poor breeding. In many cases individual kernels are 

 tinted, the yellow with white and the white with yellow 

 color. In this case it shows that a single stray pollen 

 grain has fallen upon a single silk and fertilized the 

 kernel. It is of little detriment to the variety and 

 should be judged accordingly. A rule followed by
