base, tapering rapidly to the apex, others were cylindrical, and these 
latter were more lightly husked. In some cases twin kernels appeared 
in a pod. . 
In no case were sweet kernels found in the podded ears examined, 
and in neither the podded or bare ears were flint kernels to be found, 
although sweet kernels were abundant on the unpodded. 
From our museum samples, we know that flint varieties of this pod 
corn exist, although we had no flint kinds sufficiently fresh to vegetate 
their seed. . 
This curious sort of maize has many names, such as Pod corn, Husk 
corn, Wild corn, Oregon corn, California corn, Rocky Mountain corn, 
Texan corn, Cow corn, and has an interest as believed by some to be 
the original of our cultivated kinds. White, yellow, red and purple 
varieties are mentioned. Lach kernel, in its normal form, is inclosed 
in a distinct covering, the whole ear also being enveloped in a husk, 
and the cob flimsy as compared with our cultivated races. This vari- 
ety is figured by Bonafous, plate V.; by Lindley in the Journal of 
the Horticultural Society, 1846; by Klippart, Agriculture of Ohio, 
1858; in the United States Patent Office Report, 1853, and elsewhere, 
and is spoken of by De Candolle in his Geograph-Botanique. 
Unfortunately we were unable to obtain seed of varieties, conse- 
quently we used for this season’s seed, kernels picked from ears of our 
last year’s crop. Of this we found fourteen kinds sufficiently distinct 
in color, surroundings or place of growth, and planted in all twenty- 
seven rows of four hills each. The following statistics of growth may 
prove of interest, the days of bloom before silk being for the earliest 
plant in each row:

The planting was May 16 ; for the rows, the earliest and latest head- 
ing July 27 and August 7; the earliest and latest bloom August 2 and

observations, the earliest plant in each row, and the same plant for the

We note that in these plants in one case the pollen and the silk 
developed the same day, and in the remaining cases the pollen was
