of fifty three to sixty-three pounds of grain for seventy pounds 

 of air-dried ears have been noted.^ 



Shamel states that grains with thin tips have low vitality and 

 are low in per cent of fat and protein and high in starch.^ 

 While it is evident that, other things equal, wide sulci or space 

 between rows will reduce the percentage of grain to cob, it 

 happens that some varieties, as, for example, Hickory King, 

 with large space bet\veen rows, have relatively small cobs ; hence 

 iarge percentage of grain although small weight per ear. The 

 roughness of the ear is dependent upon the character of the in- 

 dentation of the grain. Grains which cause rough ears are 

 usually longer but somewhat less compact than those causing 

 smooth ears. While a smooth ear is pleasanter to husk, there 

 are some excellent varieties whose ears are rough. Aside from 

 its influence upon husking, its importance would seem to be due 

 to the cause which produced it. If a rough ear was caused by 

 lack of proper development and resulted in chaffy, loose grains, 

 it is to be looked upon as undesirable. 



244. List of Varieties of Dent Maize. — Four white and three

 Eagle. 



Following is a list of varieties of dent 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 :
