2 "Weighted average. 



From Table 13 it will be seen that the total traffic on the Cox and 

 Halifax Roads is estimated at 63,815 tons, that the average haul for 

 the two roads is 16.4 miles, and that the average annual ton-miles 

 is 1,045,369. With the 60,000 tons of miscellaneous and forest 

 products hauled to way stations over bond-built roads an average 

 distance of about 5 miles, or a total of 300,000 ton-miles, the esti- 

 mated total traffic for the county is 1,345,369 ton-miles per annum. 

 The traffic area for the improved roads includes about 80 per cent 

 of the land area of the county, or about 266,752 acres. The tonnage 

 produced and hauled over the roads, therefore, amounts to a httle 

 over one-fourth of a ton to the acre. 



The average haul on the bond-built portion of the Hahfax Road is 

 3 miles, which for 15,002 tons makes 45,006 ton-miles, and on the 

 Cox Road about 10 miles, which for 48,813 tons makes 488,130 ton- 

 miles. By adding the 300,000 ton-miles of forest and miscellaneous 

 products hauled over the bond-built roads to local shipping stations, 

 a grand total traffic for the bond-built roads of 833,136 ton-miles is 

 secured. 



In ascertaining the tonnage and ton-mileage for the improved 

 roads, no computation was made of the motor traffic, except to count 

 the number of motor vehicles, which averaged 142 per day, but it may 

 be of interest to note in this Connection that on a tonnage basis, 

 assuming an average weight of 1.45 tons, and an average number of 

 51,830 motor vehicles passing over the roads in a year an average 

 distance of 6.2 miles, the automobile traffic represents 75,155 tons, 

 or 465,952 ton-miles, while in number of vehicles it would represent 

 27 per cent of the annual total of all vehicles. 



ESTIMATED ANNUAL SAVING ON HAULING COST. 



The average load for a double team on the old roads was about 

 2,000 pounds, and on the new roads about 3,200 pounds, although 

 much larger loads wel^ by no means uncommon. (PL X, fig. 1.) 

 The average haul for a double team on the old roads was about 10 

 miles, and on the new roads about 12.5 miles. The average cost of
