Ihe poor conditions under which the seed was produced under glass. 

 The ears, however, were not far below normal size. 



At harvest time the first thing to be observed was the very large 

 number of red grains, the average of five typical ears from the green- 

 house seed being: white, 14; black, 0, and red, 373 grains; and of 

 the same number of similar ears directly from the ear "X," white, 

 28 ; black, ; red, 4G5. These figures show that the greenhouse 

 grains produced less white ki-rnels and somewhat smaller ears than 

 the grain directly from tar "X." 



It is seen that only a snijill percentage of white grains remains in 

 this crop, which is from the planting of pink grains of a single ear 

 of the ^'Egyptian" type in 1900. 



The following table gives the numljer of rows for the best ears in 

 the two portions of the plot.

A little more than half (80 in 155) of these ears have twelve rows, 

 and this is a number that is satisfactory in sweet corn. 



Experiments in 1903. 



For the fourth year in succession Series was planted to corn, 

 each of the four plots receiving grains from separate selected solid 

 red ears of the previous crop. The season was unusually unfavorable 

 for corn, it being exceedingly dry at the proper planting time and 

 throughout ]\Iay, to be succeeded by heavy rains in June and August, 

 with winds that prostrated plants time and time again before harvest 

 time. The yield was necessarily light, but from the size of the stalks 

 and ears it was evident that under ordinary circumstances the crop 

 would liave been satisfactory. The number of solid red ears was 

 very large, and seed has been selected from the best of these for 

 future planting. Four sample ears are shown in Plato I., and upon 

 the left is shown an ear of the male parent, ''Black Mexican," and
