On tho California we have treated 16 and 22 foot 

 poloe for permanent improvement work, at E. total ooat of 



oontn nor "Ola, usln.t creosote drums as treating tanlos. 

 7hoy rare, of courue, secsonod polos, as flrrcon poles ro- 

 ouire an excessive amount of time in treating. 



So-ne yor.rs a^o the Service, in cooperation with 

 several electric compc-jniee of Sou -horn California orooootod 

 sovorrl hundred 40 foot polos. An absorption of 6 pounds 

 per cubic foot, rnd an average penetration of 5 inches r;as 

 secured on 7 feet of the butto, r.t a cost of .-1.24 per polo. 

 An inspection nado Ir.st September, shored these poloo to bo 

 perfectly sound, v.'horoas C6 percent of those that wore set 

 untreated at the er.rae tine wore thoroughly rotten at the 

 -rounr line. This vts 3 years e.ftor sotting. As tho 

 treated poles had to loot only nine nonlhs longer than the 

 untreated ones to pay for the cost of treatment, tho BUCCCCS 

 of tho experi'lon- ib obvious.
