The manure may be hauled upon the sod when other work does not press,
and it goes where the crop is one that prefers fresh manure, be that
the grass or the corn. There is plenty of time after the corn to
prepare for oats, and after the oats to prepare for wheat. The
preparation for the wheat is sufficient for the clover and timothy. The
seedings come only in the spring and the fall, when rainfall is more
abundant and effective than in mid-summer. The danger of failure in
case of this rotation is relatively small.

Corn Two Years.--Hunt says that the prosperity of the east, as a whole,
would be greatly increased if the rotations of crops were so modified
as to increase the corn acreage. He suggests the four rotations given
in the table below, which is taken from Bulletin 116 of the
Pennsylvania experiment station. The fertilizers recommended should
maintain fertility.

The Oat Crop.--In the northern part of the corn belt the oat crop is
profitable. In the southern half of Ohio and regions of like temperature
the oat crop rarely pays. The heat, when the oat is in the milk stage,
usually is too great. The tendency there is to eliminate this crop.
Where silage is wanted, the stubble-land can be seeded directly to
wheat wi
