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-
