Thus the germinative per cent of the two ears was: 426 kernels 
planted, 388 grew, or 91 per cent for the ear on the unmanured soil ; 
and 345 kernels planted, 335 grew, or 97 per cent for the ear on the 
manured soil. Of the 80 butt kernels, 56 kernels or 70 per cent ger- 
minated ; of the 611 central kernels, 589 kernels or 96 per cent 
germinated ; of the 80 tip kernels, 78 ‘kernels or 97-5 per cent ger- 
minated. We may, however, conclude that in general on normal, 
well-selected ears, the tip and butt kernels are as likely to grow as are 
the central kernels, and furnish equally well-appearing plants. 
We next separated the merchantable and unmerchantable corn, and 
obtained the following figures:

Re-calculating the ferires in this table so as to give the yield per 
plant, by estimating the missing kernels as are productive with 
the grain-bearing plants, we have:
