LIFE AND DEPRECIATION OF TRUCKS. 
The average first cost, life, and depreciation per year and per mile 
of travel for the trucks of different sizes are shown in Table XVI :

The quoted price of the truck often does not include some equip- 
ment which it is necessary or desirable to have, and each man was 
asked to report not only the first cost of his truck but also the cost 
of any extra equipment he had purchased for it. It was found that 
about two-thirds of the men had bought some equipment which was 
not included in the quoted price. This extra equipment varied from 
minor attachments costing only $2 or $3 to bodies and cabs costing 
as much as $200 or $300. As shown in the table, the amount spent for 
this extra equipment has been added to the reported first cost to 
obtain the total cost. 
Three men reported that they own trailers for use with their motor 
trucks. However, the cost of these trailers was not included in the 
total cost of the trucks. 
The total life of the trucks was figured by adding the present age — 
that is, the average number of years which the trucks had been 
owned — to the average of the estimates of the remaining number of 
years for which the trucks will give satisfactory service. The re-
