covering about one fifth of the surface, in which the grains 
were white with fine red streaks. The excellent plate ac- 
companying the account, however, shows that most of the 
"red" grains had white streaks at the crown and that the 
cob was light-colored, not red. From the near-red grains 
of this ear there was produced a crop of 84 red ears and 
86 pure white ones, while from the variegated grains of 
the same ear there came 39 light variegated ears and 36 
white ones. Hartley refers to the parent ear as a "sport 
or sudden variation from the type" but does not indicate 
whether the "type" in mind was the white variety or the 
red ears occasionally produced by it. Both the color of 
the grains and cob and the production of about 50 per 
cent, of white ears from both the red and the variegated 
grains indicate very clearly that the parent ear was a 
heterozygous, variegated one and that it probably came 
from a white seed crossed by a stray grain of pollen from 
a variegated-eared plant, just as the occasional red ears 
in the white variety were certainly produced by stray pol- 
len from red-eared plants. 
More recently East and Hayes 5 reported like behavior 
of a similarly variegated ear. An ear having on one side 
solid red grains and on the other white and very light 
variegated grains, similar to some of the "freak" ears 
noted earlier in this paper furnished the material for the 
test. The ear was produced from a white seed in a field 
of otherwise pure white corn and was therefore doubtless 
heterozygous for pericarp color and was probably pol- 
linated in large part from plants without pericarp color, 
so that 50 per cent, white-eared plants were to be expected 
in its progeny. The white, the light variegated and the 
solid red grains were planted separately. The white and 
the variegated seeds alike produced light variegated and 
white ears, 15 of the former and 15 of the latter. The red
