walking shovel plows. Fenders are used for the first plowing 
and the shovels are run from three to four inches deep. Since 
the corn is planted in furrows, the dirt always meets around 
the hills and covers all the small weeds. All the shovels are 
pointed straight ahead and the field is left level after the 
first plowing. If the ground has been packed by a beating 
rain, the harrow precedes the plow the first time over.

FIRST CULTIVATION 
The corn in this picture is about four inches tall and is being 
plowed with six-shovel riding cultivator 
or twice while it is small, it can readily be seen that the corn 
will not need to be plowed as small as is sometimes necessary 
when it is not harrowed. Before trying out the furrow open- 
ers we imagined that the first plowing would be more difficult 
than where the hill was on the level of the field; but we found 
to our satisfaction that it was much easier to do a good job 
since it is not necessary to plow so close to the hill in order
