1 Average haul includes unimproved roads. 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 little 
over one-fourth of a ton to the acre. 
The average haul on the bond-built. portion of the Halifax 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 were 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 ©
