In 1921 the cost of maintaining the work horses was computed for 
each farm. (Table 60.) This amount divided by the total hours of 
direct horse labor performed per farm gave the cost of an hour of 
direct horse labor. The cost of horse labor as thus computed was 
usually less for each farm than the current rate paid for hired horse 
labor. For this reason, the direct horse labor was charged at the 
computed rate. The charges for contract labor represent the amounts 
actually paid out for the respective crops. 
MATERIALS 
The method used in computing the cost of the irrigation water is 
explained in the discussion of Table 44. The total value of the seed 
used per acre was charged in the case of all annual crops and also red 
and alsike clover. Since alfalfa occupies the land for about three 
years on the average, one-third of the seed used per acre was charged 
to that crop. The manure charge is based on the estimated farm 
value per load. Fuel was used only in threshing wheat and hulling 
clover seed and beans.
