TIMBER-TREATING PLANTS. 



Small experimental treating plants are constructed 

 and operated on or near certain of the National Forests 

 where they would greatly increase the use and value 

 of the available supply of timber. The object of such 

 plants is to show how far preservative treatments are

 which may be used. The design of the plants varies on 

 different Forests. Some are constructed especially for 

 the treatment of telephone poles; others for ties, fence 

 posts, or other timbers. 



The conditions which make the establishment of such 

 plants advisable are: (1) A demand for considerable 

 quantities of durable timber; (2) an abundant supply 

 of dead or inferior timber on the National Forest, com- 

 bined with a scarcity of the better classes of wood; (3)

 in other useful ways. 



Recommendation for the establishment of a treating plant on 

 or in connection with a National Forest should be made to the
