VARIETIES OF MAIZE 1 67 



teen, inches ; usually seven to ten inches, with specimen ears 

 twelve inches long not uncommon. The diameter varies from 

 one and one-quarter to two inches ; usually from one and three- 

 eighths to one and five-eighths inches. The number of rows on 

 the ear varies from eight to sixteen, with eight rows the most 

 common. Twelve-rowed varieties are more common than ten- 

 rowed. A good ear of an eight-rowed variety will weigh from 

 six to seven ounces. 



The grains are hard, smooth, and more or less oval, with 

 usually white or golden orange grains, although purple, brown 

 and copper red sometimes occur. In the eight-rowed varieties 

 the t}'pical grain is one-half inch broad by three-eighths inch 

 deep ; when more than eight-rowed, three-eighths inch broad and 

 deep; in thickness, all are about one-sixth of an inch. The 

 average weight of 100 grains of an eight-rowed variety is about 

 thirt}'-three grams, or about 1,400 to the pound. 



This tyipe is reported maturing at 50° north latitude.^ The 

 season varies from ninety to 140 days, 100 to 120 days being 

 the most common. On account of its early maturit}', this t}'pe 

 is largely and principally grown in the New England States, 

 New York State, Canada and regions of similar climatic con- 

 ditions for field purposes ; rarely a variet}^ is gro\\'n for garden 

 purposes. 



Following is a list of varieties of flint maize recommended 

 principally for grain production by the stations indicated, in- 

 cluding, where possible, the color of the grain of each and the 

 number of years tested :
