MOTOR TRUCKS ON EASTERN FARMS. 19 
no great difference in the length of time during which the condition 
of the roads prevented use of trucks with different kinds of tires, is 
shown by the following : 
Of 222 owners of pneumatic-tired trucks — 
69 have all-dirt roads. 
96 have part-dirt roads. 
57 have no dirt roads. 
On the average there were 7.9 weeks during the year when the condition 
of the roads prohibited the use of the trucks. 
Of 211 owners of solid-tired trucks — 
47 have all-dirt roads. 
98 have part-dirt roads. 
66 have no dirt roads. 
On the average there were 6.4 weeks during the year when the condition 
of the roads prohibited the use of the trucks. 
Of 211 owners of trucks with pneumatic tires in front and solid tires behind — 
71 have all-dirt roads. 
104 have part-dirt roads. 
36 have no dirt roads. 
On the average there were 8.6 weeks during the year when the condition 
of the roads prohibited the use of the trucks. 
Seven out of 69 men whose trucks are equipped with pneumatic 
tires and who have dirt roads only, and 4 out of 47 whose trucks are 
equipped with solid tires and who have dirt roads only, stated that 
there was less than a week during the year in which they could not 
use their trucks. The time during which the pneumatic-tired trucks 
with all-dirt roads could not be used was practically the same as for 
the solid-tired trucks with dirt roads only, the average being between 
10 and 11 weeks in each case. 
It does not necessarily follow that horses were always used for 
hauling when the roads were in such a condition that the trucks could 
not be used, as on at least a part of these farms there was no hauling 
which it was necessary to do at such times. 
CHANGE OF MARKET. 
Each truck owner was asked to give the name of the town where 
his produce was usually marketed before the purchase of the truck, 
and its distance from the farm. He was also asked to give the name 
of the town where the produce hauled by the truck is usually mar- 
keted and its distance from the farm. Answers of 704 men to these 
questions show that about one-fourth of them have changed their 
markets since purchasing their trucks. The exact number of men 
on each type of farm who answered the questions concerning their 
markets, the number who changed markets, and the average dis- 
tance to the new markets is given in Table XII.
