It will be seen that the men who are using the smaller trucks 

 hauled comparatively small loads with their wagons; however, the 

 average size of loads of crops hauled with the h-, §-, 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 h 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 w T agon 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.
