corn from New York which had been grown near the Dutton flint. 
The ears and the kernels were apparently the true Minnesota dent. 
The crop was a flint corn, the dent character having largely dis- 
appeared. This change in variety receives again illustration in a 
planting of Dwarf Golden pop. The ears were from 1-2¥ in. 
long, with a bright yellow kernel. Thirty-six plants grew, of 
ae these thirty-two were two feet tall, the ears all like the seed except 
that one ear had a few sweet and flint kernels. The remaining 
four plants were four feet tall, and the kernels were all sweet, flint — 
or Tuscarora soft, with not a pop among them. 
From the data we have given it would seem that there is a 
ready cross-fertilization within each species, and a resistance, not 
very complete, to hybridization. But more work is yet required 
é before accepting this conclusion. : 
In this “note” I have sought to indicate how nomenclature 
can be applied to simplify the study of such a confused mass of 
‘Material as is furnished through the crossing of maize.

May 14, 1894, I received from Dr. Wm. Saunders, Director 
of the Canada Experimental Farms, a sample of the Squaw flint 
corn grown at Rat Portage, Lake of the Woods, lat. 50° N. The 
description of this variety, as made out from the cob and detached 
grains, is as below. Ear eight-rowed, six inches long; the ear 
stalk large. The taper quite pronounced from the slight dichoto- 
- Mous Openings towards the butt, and the decreased breadth of the 
kernels towards the tip. Kernels broader than deep, very flinty, 
: but the corneous matter rather thin; the larger ones 7 inch 
broad. Colors mixed, some kernels dingy white, others of shades 
_ of yellow, light purple or blue. The cob, rather squarish in sec- 
_ tion, and white; the interior reddish, the pith soft and well defined, 
: This variety seems to be the same with the Blue flint of Northern 
; New England, but the ear tapering and more squarish, although 
not more so perhaps than in individual selections from a crop 
of the Blue corn. The dichotomous arrangement of the kernels" 
and the openness between pairs can be understood by examining 
Specimens of flint tassel corn. It will be noticed with this tassel 
orn that the tassel branch becomes changed on one side toa
