depth but merely mark the dividing line between the kernels 

 from butt to tip. Where the furrow is deep, thereby expos- 

 ing a large portion of the surface of the kernel, it indicates 

 that the corn is badly off type. 



The amount of space between kernels at the cob indicates 

 maturity and vitality. The kernel tip in immature corn is 

 shriveled and therefore leaves a space readily detected. 

 In well-matured corn no noticeable space will be found, 

 but the kernels will fit tightly together from tip to crown. 



Rule for Scoring. Cut .25 of a point for -^ to iV inch 

 furrows, and cut .5 of a point for ^ inch and above. 

 Cut .5 of a point for each ear showing space between ker- 

 nels at the cob. 



PERCENTAGE OF GRAIN TO COB 



Perfect Score. The percentage of grain should equal 

 the standard for the variety. Perfect score, 10 points. 



Directions for Judging. Good, well-matured corn 

 should show a ratio of from 84 to 87 per cent grain to cob. 

 In other words, if we were to shell 100 pounds of ear corn, 

 we would get approximately 84 pounds of kernels and 16 

 pounds of cobs. The tendency with some corn growers is 

 to look for a small cob, thinking that feature of corn to be 

 the leading desirable characteristic. In many instances the 

 selection of small cobs has been practiced to such an extent 

 that the yield of grain has been materially reduced. 



One should choose a medium-sized cob that will carry 

 from 1 6 to 20 rows of kernels of medium depth. If the 

 size of the cob is reduced the ear simply drops its rows by 

 pairs until we have but 10 or 12 rows remaining. If, on 

 the other hand, the cob is too small and the grower has been 

 working for a high percentage of grain to cob, the kernels are
