This is not so much of a gain in red grains as shown for the ears 

 from the greenhouse-grown plants. This is explained above by the 

 fact that these belts grew a crop one generation nearer to the original 

 cross than the adjoining two belts. The greater number of grains per 

 ear shows that upon the same plot the greenhouse-grown plants pro- 

 duce smaller ears than those raised in the field. 



Something of the character of the ears may be gained from the 

 following table :

Plate 1. shows four ears from the above lot of corn. The one upon 

 the left is untreated; the next to the right is from the greenhouse- 

 grown seed; the next ear was close-fertilized, and the one upon the 

 right was cross-fertilized. It remains to be seen what the relative 

 vitality of the grains from these ears may be. 



Selecting Corn for Prolifioness. 



The work of selecting corn for prolifioness was continued the pres- 

 ent season. Plate IT. shows the two stalks that were selected in Sep- 

 tember, 1900, as the beginning of this work. One stalk is standing in 

 its place in the plot (lY., series VL), and another, with triple ears, is 

 placed b}' its side for the photograph. It may be seen that the six 

 ears are all evenly mixed with the dark and light grains. One stalk 

 bore ears with eight, ten and twelve rows, respectively, and the other, 

 ten, twelve and fourteen ears, respectively. 



Samples of the results of 1901 are shown in Plate III., and the re- 

 sults of this selection are given upon pages 407 and 408, in the report 

 for last vear.
