IRRIGATED FARMING IN TWIN FALLS COUNTY, IDAHO 69 
SOME OTHER FACTORS THAT AFFECT COSTS 
Of the 152 farms used in the cost studies 134 had automobiles. 
The automobile charge per crop acre ranged from $1 to $10. The 
charge was very generally larger on the small farms than on the 
larger ones; that is, the small farm requires about as much running 
about with the automobile as the large farm, and per crop acre the 
small farm is at a disadvantage.

AVERAGE ANNUAL HOURS OF LABOR PERFORMED PER HORSE PER FARM 
Fic. 22.—By its position on the chart each dot represents (1) the average hours of work performed 
annually per horse and (2) the average cost of a direct hour of horse labor on an individual farm 
in 1921. The small circles represent group averages having class limits of 100 hours. On some of 
the farms studied there were more than twice as many work horses as were needed to do the farm 
work. Hence the wide variation in the cost of horse labor per hour 
In the cost studies taxes varied from a little less than $2 per crop 
acre to as much as $12. The wide variation in taxes was mainly due 
ao ee and road districts in which the respective farms were 
ocated. : 
The interest charged against each of the crops for the use of land 
and equipment varied from less than $11 per crop acre to $38. 
Interest reflects in a general way the different grades of land. It is 
very probable, however, that some of the land was overvalued and 
some undervalued.
