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, wliether 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-rowed yellow.
