Steep grades on the logging roads make it very desirable to use 

 locomotives which have a maximum amount of traction. For this 

 reason, a geared type locomotive is used which [x^rmils a big reduc- 

 tion between the engine and drive wheels, and also transmits the 

 drixing torque to all wheels of the engine and coal tender which is 

 shown, and also to the wheels of the water tender which is not shown 

 in Fig. 7. 



From one to ten car loads of poles in a grouj) arri\'e at the trealini; 

 plants. A car load varies between 40 and 65 poles depending upon

ihe sizes of the |)oles. They nia\- be unloaded by a locomotive crane 

 or a tractor crane or b\ the iiuiliod shown in Fig. !). 



At the Shijjman \'cU(i liie jxiies are unloaded b\- cutting the stakes 

 and permitting the poles to roll down an embankment into piles 

 from which they are drawn to the treating plant by means of a steel 

 rope from a tractor winch. 



Utilization of the cheajiest method of delivering poles to the treat- 

 ing plants is possible at Ceredo and Nashville where the plants are 

 located on the river banks. These poles are si-curely tied in rafts of 

 about 100 poles each and either floated down tin- rixcrs or handled
