IS BULLETIN 031, U. S. DEPARTMENT OF AGRICULTURE. 



The exact number of weeks these men who have roads which are all 

 or part dirt could not use their trucks is as follows : 



Of 152 men who use pneumatic tires — 



15 were able to use their trucks every week in the year. 

 58 were unable to use them for 1 to 4 weeks in the year. 

 37 were unable to use them for 5 to 8 weeks in the year. 

 25 were unable to use them for 9 to 12 weeks in the year. 

 7 were unable to use them for 13 to 16 weeks in the year. 



7 were unable to use them for 17 to 20 weeks in the year. 

 3 were unable to use them for 21 weeks or more. 



Of 211 men who use solid tires — 



3 were able to use their trucks every week in the year. 

 56 were unable to use them for 1 to 4 weeks in the year. 

 55 were unable to use them for 5 to 8 weeks in the year. 

 48 were unable to use them for 9 to 12 weeks in the year. 

 28 were unable to use them for 13 to 16 weeks in the year. 



8 were unable to use them for 17 to 20 weeks in the year. 

 13 were unable to use them for 21 weeks or more. 



Of 338 men who use pneumatic tires in front and solid tires in the rear — 

 15 were able to use their trucks every week in the year. 

 82 were unable to use them for 1 to 4 weeks in the year. 

 96 were unable to use them for 5 to 8 weeks in the year. 

 77 were unable to use them for 9 to 12 weeks in the year. 



27 were unable to use them for 13 to 16 weeks in the year. 



28 were unable to use them for 17 to 20 weeks in the year. 

 13 were unable to use them for 21 weeks or more. 



Ten per cent of these men who have pneumatic-tired trucks were 

 able to use them every week in the year, and less than 30 per cent 

 were laid up for more than eight weeks by poor roads. Less than 2 

 per cent of the men whose trucks were equipped with solid tires were 

 able to use them every week, and over 45 per cent of them were laid 

 up for more than eight weeks. 



Forty-five men who have all improved roads reported the kind of 

 tires with which their trucks are equipped. Two of them are 

 equipped with pneumatic tires, 3 with solid tires, and 40 with pneu- 

 matics in front and solids in rear. 



The number of weeks during the year these 45 trucks could not be 

 used is as follows : 



12 could be used every week. 



10 could not be used for 1 to 4 weeks. 



6 could not be used for 5 to 8 weeks. 



7 could not be used for 9 to 12 weeks. 



4 could not be used for 13 or more weeks. 



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 

 1 1 nuling which it was necessary to do at such times.
