the corn is cut and husked from the shock, the average labor require- 
ments were about 53 man hours and 56 horse hours per acre. 
In Kansas and Nebraska a large acreage of corn was listed. How- 
ever, in the Kansas area the total hours per acre where the ground 
was plowed and planted in the regular way were practically the same 
as the total hours reported when listing was practiced. In Nebraska 
the man hours were slightly less with listing and the horse labor 
about 9 hours less than in cases where the land was plowed. 
The usual practice in the two Iowa districts included stalk cutting, 
plowing with a two-bottom gang, disk (once), spike-harrow (twice), 
occasionally roll, plant with a two-row check planter, harrow twice 
while corn is small, and cultivate three times. Essentially the same 
treatment was given on the Illinois farms. Indiana operators plowed 
the land with walking and sulky plows, then disked, harrowed from 
one to three times, rolled occasionally, and planted with a two-row 
check planter. The spike-tooth harrow and roller were also used 
for the first cultivation and corn was cultivated about four times 
with a one-row implement. Practically the same treatment was 
given in Ohio.

a The labor and material requirements as reported constitute 85 per cent of the operating expense in 
the corn belt and 88 per cent in eastern districts. 
For the eastern districts field practice differed appreciably from 
practice in the central part of the corn belt. Three-horse walking 
plows were used quite generally. The disk was not employed to
