DISPOSAL OF IRRIGATED CROPS THROUGH THE USE OF HOGS. 6 
the condiments fed, sprays used, interest on investment, risk, and 
labor are not considered in this report. The term "net return," as 
used in the following text and tables, refers to the difference between 
the total return and the estimated value of grain fed and is not to be 
taken as the net return of the land after production costs and interest 
charges have been deducted. 
The hogs in these experiments had access to salt, slacked coal, and 
rock phosphate most of the time. They were also sprayed with coal-tar 
creosote every two or three weeks to keep them free from lice. In fact, 
they received the treatment that every farmer should give his hogs. 
The hog usually receives the least care and consideration of any 
farm animal. It is commonly believed that anything is good enough 
for hogs, but, on the contrary, the hog will respond as much to good 
care and treatment as any kind of live stock. Regularity in feeding, 
both in time and quantity of feed, clean quarters, and freedom from 
lice are three very important factors that are essential to successful 
hog raising; and these were provided in the experiments under con- 
sideration. The data here reported are the results of tests covering 
one to four years. In the alfalfa pasturing experiment, two lots of 
hogs were used each season, and in the corn hogging experiment, 
with supplemental feeds, duplicate lots were used. 
ALFALFA PASTURING EXPERIMENTS. 
ALFALFA PASTURE SUPPLEMENTED WITH A 2 PER CENT RATION OF CORN. 
The alfalfa pasturing experiments were begun in 1913 and con- 
tinued in 1914 and 1915. Each year a quarter-acre plat was used. 
The plat was divided into two equal parts and the hogs were changed 
from one to the other as the pasture became short. This allowed the 
alfalfa to recuperate and at the same time provided fresh, palatable 
feed. It was the plan to pasture the alfalfa to its full carrying 
capacity but not to overgraze. This made it necessary to remove 
some of the hogs during the latter part of the experiment, for as 
the season advanced and the nights became cool the alfalfa made 
slower growth and at the same time the hogs were increasing in size, 
thus requiring more feed. A few times during periods of three or 
four days of cloudy weather and also during the last month, when 
alfalfa was making little growth, the plats were perhaps slightly 
overpastured. As far as could be determined, however, no plat was 
pastured more heavily than another. 
The corn was fed on the ear during the first period, and shelled 
corn was fed during the second period. Ear corn was fed on the 
ground and the shelled corn in a trough. The barley was ground and 
fed as a thick slop. Grain was fed once a day, in the evening. It is 
believed that when fed grain but once a day the hogs will make more
