The results given in the above table show the great differences with 

 respect to yielding power that exist among varieties. Although these 

 varieties were grown under identical conditions, there is a range in average 

 yields from 65.1 bushels for Lincoln to 44.2 bushels for Golden Giant Side. 

 There is also considerable difference in weight per bushel. The weight 

 varies from 31.62 pounds for White Tartar King to 28.31 pounds for 

 Golden Giant Side. The difference in size or weight of kernel and in per- 

 centage of meat in the different varieties is very marked. This is shown 

 by the following table:

From this table it is apparent that, although kernels may be of nearly 

 the same size, there is a great difference in the amount of meat. For 

 example, although the weight of one hundred seeds of Swedish Select is 

 nearly equal to that of one hundred seeds of Lincoln, the percentage of
