The dent corn used in these experiments was an unnamed strain 

 which has been grown for a long period of years (at least 15) by 

 Mr. Hiram Cornforth of Waterville, Maine. It is an early maturing 

 yellow dent, producing ears of fair size, but not very uniform quahty.

It has been inbred for a long period, all of the corn forming this 

 strain being descended from a very few original ears. Is has never 

 been specially selected for uniformity with respect to shape of ear, 

 size and shape of kernel, etc., and on this account varies to some 

 extent with reference to these characters. The appearance of a typical 

 ear of this yellow, dent maize is shown in fig. iß. 



Both the dent and the sweet com used in these experiments are 

 known from direct experimentation and observation on the part of
