The average age of the trucks which had been owned 37 months 
or more was not far from 4 years, and on this basis the average 
annual repair costs for the first 4 years of these trucks' lives were 
approximately $35 for the -|-ton trucks, $50 for the f-ton, $40 for 
the 1-ton, $35 for the l|-ton and l|-ton, and $110 for the 2-ton. It 
is apparent that these figures are too low for the average annual 
repair cost for the entire life of the machines, but since none of the 
machines reported on were entirely worn out it is impossible to 
obtain accurate figures for this item. In the absence of accurate 
figures, allowances of $50 per year for the -|-ton trucks, $75 for the 
f-ton trucks, $75 for the 1-ton trucks, $100 for the 1^-ton and 1^-ton 
trucks, and $150 for the 2-ton trucks, have been made as fair charges 
for the average annual repair costs in figuring the cost of operation 
in Table XX on page 32. 
GASOLINE AND OIL. 
The average number of miles obtained per gallon of gasoline and 
per quart of cylinder oil by the men who use trucks of different sizes
