It will be seen that the men who are using the smaller trncks 
hauled comparatively small loads with their wagons: however, the 
average size of loads of crops hauled with the §-, J-, and 1-ton trucks 
is less than the average size of loads which were formerly hauled 
with wagons. The same is true with feed and fertilizer. 
Milk was hauled almost entirely with 1-ton trucks or smaller, only 
7 of 139 men who reported hauling milk having trucks larger 
than 1 ton. The size of load is smaller and the distance hauled is 
shorter for milk than for the other three materials. For each size 
of truck the average distance crops are hauled is slightly greater than 
the distance hauled with the wagons before the trucks were pur- 
chased, this difference being due to the fact that a number of men 
changed their markets after buying their trucks. 
The hours per ton-mile were arrived at by dividing the hours for 
the round trip -by the product of the distance in miles and size of 
load in tons. For instance, in Table IV the |-ton truck carrying 
a load of 960 pounds a distance of 10.4 miles accomplishes 4.99 
ton-miles of hauling. Since 2^ hours are required for making this 
trip the time required per ton-mile is 0.50 hour. A comparison 
of the hours required per ton-mile for hauling by truck with the 
hours per ton-mile required for hauling by horses and wagon gives 
the proportion of the time saved by using the truck. 
TIME SAVED BY TRUCKS. 
Table VIII shows the percentage of time which the trucks of differ- 
ent sizes are saving their owners in hauling different materials. In 
nearly every case the trucks are saving more than half of the time 
formerly required to haul with wagons.
