The corn grower can do much to hetter this condition of affairs by 

 carefully picking over his corn until all the ears show kernels of uniform 

 size and shape. A careful study of the conditions which tends to an 

 uneven stand reveals that the cause is due largely to the lack of uni- 

 formity in the size and shape of the seed planted.

B. — The kernels on earn No. 1 are nearly the same depth from tip to butt, while the 

 kernels on ear No. 2 grow rapidly shorter towards the tip. The kernels on ear No. 3 are 

 small, shallow and flinty, little larger than grains of pop corn and will run through the 

 planter about like wheat. When these three ears were shelled together and tested in the 

 planter there was a range of all the way from two to seven kernels per hill.
