From this presentation we may infer that in our duplicate plantings 
of corn, we cannot expect to secure equivalency within 3 or 4 bush- 
els of crop, and may have even as great divergence as 14 or 15 bush- 
els. It hence follows that the average interpretation of differences 
to be ascribed to fertility or treatment on our plats, cannot be with- 
in these figures. 
WHAT PORTION OF EAR TO PLANT. 
For now three successive years, our experiments in planting the 
but, central and tip kernels of corn, have given an uniform conclu- 
sion that the tip kernels are at least not inferior for seed to the other 
kernels of the ear. This years experiment is in the same direction, 
and embraces twenty plats. Hach plat was planted in nine rows, 
three rows of but, three of central and three of tip seed, the seed 
being the five but, central and tip seed of each row from the same 
ears. The fertilization was alike, 400 lbs. per acre of a phosphate. 
The variety of Corn Waushakum, in hills, four plants to a hill, the 
hills 44x42 inches apart.
