Colorado Agricultural College Farm Costs. 9 
COST OF HORSE LABOR. 
In determining the cost of horse labor, the entire cost of car¬ 
ing for the horses was included. These costs were subdivided, 
showing the interest and depreciation on harness and on the barn 
in which the horses are quartered; the man labor performed for 
or on the horses; the horse labor for horses; hay, grain, straw, 
grinding feed, chores, miscellaneous barn supplies, and interest and 
depreciation on the horses themselves. Where the progeny in¬ 
creased in value this increase in value was deducted from the total 
of the itemized costs. In other words, the increase in progeny 
value represents a credit which reduces the total cost of caring for 
the animals to the amount of the increase.

CROP COSTS. 
In determining the cost of growing specific crops for each year 
the total acreage of that crop upon the College Farm, no matter in 
what field that growth occurred, was considered. Some of the crops 
have not been grown the entire period, so that the cost for only a
