" Early Southern Corn." 

 (The sample was obtained from Messrs. J. S. Graves & Son, Hatfield, Mass.) 



The ear contained sixteen rows of kernels of a light 

 yellow color. Its average length was from ten to eleven 

 inches; and its average weight was from fifteen to sixteen 

 ounces, and consisted of eighty-two per cent of kernels and 

 eighteen per cent of cob. The average weight of one kernel 

 was .46 gram. 



The corn was raised upon Connecticut-river bottom-land, 

 upon which no manure was used, as it was in a high state of 

 cultivation. The yield amounted to about a hundred bushels 

 of shelled corn per acre. 



Tobacco had been raised upon the land the previous year.
