The annual depreciation was figured by dividing the first cost by 
the life in years, the depreciation per mile of travel by dividing the 
annual depreciation by the average number of miles traveled per year. 
A comparison of these figures with those for the cost of fuel and oil 
in Table XVI and for tires in Table XVII shows that for each size 
the depreciation charge is greater than the cost of fuel and oil. and 
for the larger sizes it is greater than the combined costs of fuel, oil, 
and tires. 
REPAIRS. 
Each truck owner was asked to report the amount he had spent for 
repairs since the purchase of his truck. A summary of the replies 
for trucks of different sizes is given in Table XV.

of the trucks of different sizes had spent are as follows:
