The above calculation is based upon the idea, under the Mendelian 

 principle, that both yellow color and flinty texture are dominant 

 ^characters over white and soft qualities, respectively, and the actual 

 count is as near as might be expected to accord with the assumption, 

 in view of the modifying circumstances. The ear showed twenty-two 

 dark grains in addition to those that have been classified in the above 

 table, and these were due to the effect of a dwarf purple popcorn that 

 was grown in the vicinity of the "Ruby" without the expectation that 

 the flowering season of the two sorts would in the least overlap. All 

 of the dark grains are of the flint type, as expected, and a majority 

 of them show a mixture with the yellow. 



Color of the Cob. 



The color of the cob is perhaps a character that obeys the Men- 

 delian rule in breeding. Thus a block of twenty hills of "Black 

 Mexican" upon "Early Windsor," the latter having a reddish or 

 "rusty" cob, gave thirty-three ears, ten of which were with white cobs 

 and twenty-three with a color like the'mother of the cross. In another 

 block was grown a cross of "Perry's Hybrid" upon "Ne Plus Ultra," 

 the former having the reddish cob quite frequently, and as a result 

 there were seventeen "rusty" and twenty-three white cobs. Failure of 

 a nearer approach to the theoretical ratio of three to one (the colored 

 cob naturally assumed to be the dominant) may be found in the fact
