CORN. 
In some of the tests here reported the corn has been hogged off 
without any supplementary feed being used with the corn. In 
others, the corn was supplemented in various ways. The hogs usually 
were turned into the cornfields at about the time the corn was well 
dented. They remained there for varying lengths of time, depending 
on the size of the field, the number and size of the hogs, and the quan- 
tity of feed available. Usually the period ranged from 20 to 40 
days, but sometimes it was 60 days or longer. A view of a field in 
which hogging was continued into the late autumn is shown in 
figure 5. 
Hogging com without supplementary feed. — The results secured 
with 23 lots of hogs which harvested corn without supplementary 
feed have been tabulated. These tests were made at the Scottsbluff, 
Huntley, and Belle Fourche Experiment Farms, and in cooperation 
with farmers on the Xorth Platte and Huntley Keclamation Proj- 
ects. The results are shown in Table XVII.

1 Fractions are omitted from figures showing estimated yields but are included in the calculations of the 
corn consumed per 100 pounds of gain. 
The data shown in Table XVII involved 198 hogs and about 23 
acres of corn. It will be observed that most of the fields were small.
