ern section for dent corn are 6^2 to 7 inches in circumference; 

 central section, 6J4 to 7J4 inches; southern section, 7 to 8 

 inches. Measure the circumference at one-third the distance 

 from the butt to the tip of the ear. 



10. (a) Furrows Between Rows. The furrows between the 

 rows of kernels should be of sufficient size to allow the corn to 

 dry readily, but not so large as to lose in proportion of corn to 

 cob. (b) Space Between Tips of Kernels at Cob. This is very

objectionable, as it indicates immaturity, poor constitution, 

 and poor feeding value. 



11. Proportion of Corn to Cob. Depth of kernels, size of 

 cob, maturity, furrows and space at cob all affect the propor- 

 tion. The corn may be selected and judged by those features. 

 But if scales are available the proportion of corn is determined 

 by weight. In determining the proportion of corn to cob, 

 weigh and shell an average ear in the sample. Weigh cob and 

 subtract from weight of ear. This will give weight of corn; 

 divide weight of corn by total weight of ear, which will give 

 per cent of corn. Per cent of corn should be from 86 to 87. 

 For each per cent short of standard, a cut of one and one-half 

 points should be made.
