TRACTION ENGINES FOR WAGON HAUL 



Traction engines are used for transporting logs from the woods 

 to the mill where the amount of timber to be hauled is not great 

 enough to warrant the construction of a railroad, where the 

 grades are unfavorable for the use of animals and where timber 

 of large size and great weight must be handled. They are used 

 to a limited extent in the southern states but are more common 

 in the Northwest and in California. 



A traction engine to give the best results requires a good stone 

 road but it works well on solid earth bottom. The ordinary 

 4-wheeled type is not successful in very swampy places, on very 

 rough roads or on dirt bottom during rainy periods because the 

 traction wheels soon render the road impassable. 



Four-wheeled. — This traction engine has a locomotive-type 

 boiler carrying about 165 pounds' steam pressure, and is equipped 

 to burn either coal, wood or oil. The boiler and other parts of 

 the engine are mainly supported on two traction wheels running 

 on axles attached on opposite sides of the fire box. The diameter

 per thousand add from 15 to 20 cents per thousand to above prices. For oak add 

 50 cents per thousand.
