Preservative Treatment of Telephone Poles 

 by the "Bouohorle" Prooesa. 



J. H. Horwege 



It Is the general purpose of the work outlined In the 

 experiment, vrhioh is located at the North Bloonfield Ranger 

 Station, to determine whether or not the "Boucherie" process is 

 adapted to the preservative treatment of poles under oonditlons 

 met with in constructing telephone lines on the National Forests, 



The experiments are planned to ascertain: 



(a) The factors influencing the treatment of each 

 species such as tfto effect of daily tempera turo, 

 season of cutting, and seasoning upon rate of 

 absorption; also, the effect of water storage 

 and of varying solution pressures at poltft^of 



a^opli cation. 



(b) Length of service resulting from treatment. 



(o) Detailed cost of oach step in process. 



Four hundred and sixty-eight poles are to be treated 

 at the plant, selected as follows: 



245 Yfhito Fir 

 205 Western Yellow Pine 

 9 Douglas ?ir 

 9 Incense Cedar 



The main apparatus consists of a skidway composed of 

 three peeled poles 60 feet long, laid parallel 8 feet apart. 

 The first skid pole is raised about 16 inches higher than the 

 others eo as to give tho poles a slant during treatment. On or 

 near the ground and parallel to the first skid pole, a half inch
