CORN

cumference; central section, 6 5^ to 7}^ 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. (h) Space Between Tips of Kernels at Cob. — 

 This is very objectionable, as it indicates immaturity, poor 

 constitution, and poor feeding value.

 at Omaha in 1908. (Agricultural Education.) 



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

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

 portion. 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 the cob and subtract from the weight of the ear. 

 This will give the weight of the corn; divide the weight of the 

 corn by the total weight of ear, which will give the 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.
