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.

In all, 40 per cent of the men who had not owned their trucks 12 

 months had spent nothing on them for repairs. However, very few 

 of those who had owned their trucks for more than 12 months had 

 been free from expense for repairs. The amounts which the owners 

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