The fact that a man has changed his market does not necessarily 
mean that he hauls all of his produce to the new market or that he 
purchases all of his supplies from that place. In fact, a considerable 
number still haul some material either to or from the old market. 
Before they purchased trucks 80 per cent of these 215 men used 
markets which were less than 10 miles from their farms, but now 75 
per cent of them are using markets which are 10 miles or more dis- 
tant. One hundred and two of them now use markets which are 15 
miles or more from their farms, yet only 159 of the entire 814 are 
using markets which are 15 miles or more from their farms. Thus 
two-thirds of all the men who now use markets which are so far from 
their farms are men who have changed markets since purchasing

ANNUAL USE OF TRUCKS. 
The number of miles per year which a truck travels has a direct 
bearing on the cost per mile run or per ton hauled. Depreciation, 
interest, and repairs are all more or less independent of the number 
of miles per year which a truck runs, and the greater the number of 
miles traveled per year the less will be the cost per mile for these 
items. Table XV gives the average of the estimates of the days per 
year on which they are used and the number of miles traveled per 
year for trucks of different sizes. The days per year on which the 
truck is used does not mean the number of full days' work which the 
truck does, but simply the number of days during the year on which 
some use was found for it.

In general the smaller trucks are used on a greater number of davs 
and travel a greater number of miles per year. However, the indi- 
vidual reports show that there is no very close relation between the 
size of the truck and the miles traveled per year. For the farms 
under consideration the amount of material to be hauled, the length 
of haul, and the size of truck are all corelated in such a way that no 
one factor exerts a predominant influence. 
The exact number who estimated that their trucks travel different 
distances per year is as follows :
