well developed. Kernels very hard, and set close upon the axis or cob ; pointed, higher 
than wide. Rows irregular at their base. Corneous portion thick; groove single and 
wide. Specific gravity, 1 ‘289. The cob of this variety is small, and the kind is early. 
It is esteemed by the Vermont farmers. 
9. Canada pop-corn, Egyptian corn (fig. 4). Yellow. Color blue and dark purplish-red. 
Ear small, firm and hard. Cob small and reddish. There are several varieties of the 
yellow and the dark colored, all of them early and small, and used only for popping.

10. Rice corn. White and yellow. Kernel pointed, mucronate, or the back terminates 
in a point where the silk was inserted. Rows 12 - 16, and irregular at base. Ear 4 to 6 
inches long, and tapering. It is a beautiful variety, and probably one of the richest and 
sweetest. It bears from three to four ears on a stalk, but is rather unproductive. It is 
used principally for popping.

12. Kernels small, pointed, rounded upon the back. It is an unproductive kind, bear¬

portion placed upon the side; back indented. Starch extends to the investing membrane. 
Size remarkably large, and ears from 12 to 14 inches long. It has 868 kernels upon an 
ear, in 12 to 14 rows. Cob reddish and chaffy. One hundred and seventy bushels of this 
corn have been raised upon an acre. 
13. Virginia Golden corn (fig. 9). Reddish-yellow, polished. 
14. Kentucky corn (fig. 8). Kernel white, somewhat shrivelled, elongated and pointed. 
Both these varieties are starchy and light, and are known in market as Ohio or Southern 
corn.
