somewhat swollen. The number of twelve-rowed ears exceeded all 

 others, numbers which ranged from eight to sixteen showing that the 

 mother plant ("Egyptian"') had a very decided influence. 



Experiments in 1901. 



Plot IV., Series YL, was again jdanted to sweet corn, and the 

 seed used was the pink grains from eight ears of the previous crop, 

 and all having over ten rows upon the cob. The plants thus produced 

 were remarkable for their vigor and size. At harvest time the first 

 things observed was the greatly increased amount of red in the ears. 

 The average of five typical ears gave 90 white, 81 black and 261 red 

 grains. The number of grains per ear had increased considerably 

 over the previous year, a feature of no small consequence when many 

 rows is an advantage in sweet corn. 



A greater variation in the ears was observed. In 1900 the ears 

 were practically alike, but this season they ranged all the way from 

 those with about half white grains to those in which the color was 

 entirely red. It was also noted that nearly all the ears were more 

 than eight-rowed, and this characteristic of the "Mexican" variety 

 is largely lost from sight. 



Experiments in 1902. 



For the third successive season Plot lY., Series YL, was planted 

 to sweet corn. From the previous crop a fine, solid-red, ten-rowed 

 ear was selected and marked "X" ("Extra") at the time of harvest. 

 For this some grains were taken, and a dozen plants growTi in the 

 gTcenhouse during the winter of 1901-3. Several ears were thus 

 produced, all short, however, because of the unfavorable conditions 

 for the best growth of corn, and from these, which were solid red, 

 seed was selected for one-third of the plot, namely, belts 1 and 2. 

 The remaining two-thirds of the plot was planted with grains from 

 ihe ear marked "X" — that is, the mother ear of the greenhouse corn 

 above mentioned. In other words, the whole plot was planted with 

 ihe product of the same year; only the first two belts bore plants one 

 generation further from the original cross of "Black Mexican" and 

 ^'Egyptian." The greenhouse-grown seed produced smaller plants 

 than in the other portion of the plot, a difference to be attributed to
