ANALYSES OF MAIZE.

Tuscarora becomes a pure kind, and free from intermixture. The result is much like 
grafting or budding. The stock may influence the character of the fruit, but still it re¬ 
tains very much of its own individuality. 
The question, however, which I wished to determine definitely in bringing up this 
subject, is, whether these kinds, growing thus together upon one cob or in one habitation, 
are really as different in the internal constitution as they are in their external appearance. 
Jackson maintains they are, and with good reason; but his opinion was not founded upon 
a real analysis. I have therefore attempted to settle the question in this way. I accordingly 
selected an ear bearing the Tuscarora, a large 8-rowed yellow, and the Sweet corn varieties, 
which are at the extremes in appearance, here meet upon one ground, and hence were 
subjects suitable for my inquiry. Another variety, however, seemed to have originated 
in the relations in which these stood to each other in the field — a variety between the 
Tuscarora and the 8-ro.wed yellow.
