removed from those which are of a uniform type, it is not so

 butt kernels be removed from these ears before the bulk of 

 the corn is shelled for seed. If this is done, a reasonably

 the seed uniformly. A, the ungraded sample; B, the large, uniform kernels

74. Germination. Experiments conducted by a number 

 of experiment stations indicate conclusively that there is a 

 very close relation between the stand of corn and the jaeld. 

 This being true, it is of great importance that only such seed 

 as is known to be of strong germination be planted. If 100 

 kernels from a uniform sample of corn are taken and each
