166 PRACTICAL CORN CULTURE 
The corn cultivation is usually begun as soon as the corn rows 
can be followed: I prefer quite deep cultivation the first time over, 
growing shallower and further from the row as the corn roots spread. 
We use nearly altogether the shovel cultivators, but I am quite certain 
the surface cultivators for the third and (if any) succeeding cultiva- 
tions, would be better than shovels. 
Owing to the pressure of other work we rarely cultivate more than 
three timies, as the corn gets too big for later plowings. 
I am firmly convinced that we could increase the yield five to ten 
bushels per acre by breaking the crust between rows after the coin 
is too big to cultivate otherwise. 
Yours truly, W.
