On the basis of S2 per day for single teams, $3 per day for double 

 teams, and $4 a day for three-horse teams, for the four cases in which 

 complete information was secured, the average cost for the 44.7 ton- 

 miles moved was 29 cents per ton-mile. For the entu'e 16 cases 

 referred to the cost per ton-mile would be much higher, as most 

 'of them represented only partial loads. (See PL V, fig. 1.) 



In the winter and spring months the average weight of load for a 

 two-horse team was about 20 bushels of grain, or about 1,200 pounds. 

 When the roads were diy, 40 bushels of grain, or 2,400 pounds, made 

 an average load. On the basis of a 10-mile haul, and $3 per day for 

 man and team, the cost would be 25 cents per ton-mile on the roads 

 when dry, 50 cents when the roads are wet and muddy, and at least 

 30 cents for the year around. 



The 1912 inspection was made March 19, 20, and 21, after the road 

 from Fredericksburg to Spotsylvania Court House, llf miles, had 

 been completed. The average load for a two-horse team on this road 

 was now found to be 1,000 feet of lumber, or about 4,000 pounds. 

 On the basis of a 10-mile haul, and S3 per day for man and team, the 

 cost was 15 cents per ton-mile.
