CO-OPERATIVE TIMBER PRESERVING PLANT. 



During October, 1911, the Forest Service, through its officers

 are so arranged that the preservative material can be heated by 

 means of steam from the boiler which is passed through coils of 

 pipe in the bottom of each tank. The preservative fluid is first 

 drawn from the storage tank into the dipping tank, where the 

 posts, shingles, or other timbers are placed for treatment. Here 

 the temperature is raised to the desired point for a specified length

 is situated below the floor for this purpose. From this tank the 

 material is then pumped back into the storage tank by means of 

 the steam pump.

 timbers as fence posts, shingles, and other small pieces of timber.
