ting. The hauler then need not remain during unloading but 

 can at once start on the return trip to the skidways with the 

 empties from the preceding turn. This method of operation 

 necessitates the use of three sets of sleds; namely, one at the 

 skidways, one on the road and one at the landing. The in- 

 creased cost of equipment is more than offset by the greater 

 capacity of the hauler and the decreased labor cost at the 

 landing. 



Haulers in the Adirondacks have carried fifteen cords of 

 spruce pulp wood over roads having 10 and 11 per cent grades. 

 Distance records of 84 miles in twenty-four hours have been 

 reported. The heaviest loads have been hauled in the Lake 

 States on ice roads. A single log hauler in Wisconsin has hauled 

 fourteen sled loads of hardwood in one train, each sled bearing 

 from 6000 to 7000 feet, making three or four trips daily on a 

 round-trip of 1 2 miles. In Minnesota, trains of nine sleds, each 

 bearing 12,000 feet of white and Norway pine, have been trans- 

 ported by one hauler. 



The average cost of operating a hauler of this character in 

 Ontario was $15 per day for coal and oil, and $15 for wages and 

 board of the train crew. The hauler made three turns daily on 

 a road between 7 and 8 miles long hauling from nine to twelve 

 sleds per trip, an average of thirty loads. Each sled carried 

 eighty logs, or a total daily haul of 2400 logs. The company 

 estimated that the hauler did the work of twenty teams at a 

 reduction of $25 daily for wages, and from $10 to $15 saving in 

 the amount that would have been expended for horse feed. A 

 further saving was effected during the summer months since idle 

 horses cost from $25 to $40 each to feed while there is no expense 

 for the hauler.^ 



A record^ of one machine for a season's haul in Stetson Town, 

 Franklin County, Maine, from January 11 to March 6, 1907, 

 running day and night shifts, is shown in the following:
