brass pipo, consisting. of forty 18-inch sections which are 

 threaded on each end and connected to each other with "brass 

 tees, is laid. Into oach tee at right angles to the main 

 feed pipes, a 4- inch piece of brass pipe is screwed, to which 

 a piece of 3/4-inch rubber hoso is attached which terminates 

 in a wooden spigot. 



At one end of the skid way at a height of 25 feet from 

 the ground a platform is built, upon which six barrels are 

 placed and are 'connected with siphons. Prom the bottom of one 

 of the barrels, and fastened to it by a piece of --inoh brass 

 pipe, a 28-ft. length of 3/4~inoh rubber hose is connected v/lth 

 the feed pipe along the skidway. This gives the pressure to 

 foroo the solution Into the poles. 



The poles are rolled upon the skids so that eaoh butt* 

 is opposite one of the rubber offshoots from the main feed pipe. 

 A rin of 1/S-inoh composition pao!cing is then fastened to tho 

 end of eaoh pole just inside the bark. A squaro piece* of 1 or 

 lir inch dry cedar board is then placed over the packing. This 

 board is tightly drawn up against the packing by means of two' 

 lag-belts which are driven into the poles opposite eaoh other, 

 ana passed through a slotted pieoe of 2jc4 wooden strip, which 

 bears against the butt-plates ' and IB screwed tight, moving a close 

 fas toning 'against the packing. A email chamber is thus formed at 

 each butt. A 6/8-lnoh hole is bored Into eaoh butt-plato to ad- 

 mit the wooden spigot through which the solution Is forced from 

 the main feed pipe. 



The solution is made as follows: 



The required amount of copper sulphate, 



(about five pounds of the dry salt to 40 gallons of water), is 

 weighed and dumped into a pail. Hot water is then added and 

 stirred with a wooden paddle until the salt is dissolved. The 

 concentrated solution is then poured into mixing barrels filled 

 with v/ater and again thoroughly stirred,' Eio solution is then 

 puaped into the pressure barrels for use. 



'After being connected and the preservative solution 

 turned on, the unpeeled poles are allowed to remain on the skid- 

 way until the preservative solution begins to appqpgK uniformly 

 throughout the top. It is sometimes nooees&ry to turn the pol&a 

 so as to make the solution take effect on the J^op side of the 

 pole. Tho average time that it takes to treat the poles is 

 about five days. 



Sixty-five of the treated poles will be used in the 

 telephone line which will be constructed this Summer from the 

 Bloomfield to the Miller's Ranch Stations.
