Of course, the sharper the railroad cur\es can be made in la\ing 

 out a siding from the railroad into the pole treating yard, the easier 

 it is to accommodate the siding to cramped yard conditions or to 

 spread out the tracks over a short, wide yard. However, due to the 

 use of heavy locomotives on the main lines and the desirability of 

 having switch curves suitable for the locomotives ordinariK- used, 

 it has been necessary to use 12 degree railroad curves in planning 

 most of the yard entrances, and in no case has a cur\c Iwen used 

 which is sharper than 18 degrees. 



It will be noted from Fig. 3 that the pole treating apparatus is so 

 located that the work of hantiling poles to and from the treating 

 tanks will not interfere in any way with loading outgoing cars of 

 treated poles from the skids. It will also be noted that the poles 

 which are received from the river are treated during the natural 

 course of their passage to the "treated" skids.
