Book Description

Excerpt from Preservation of Dead Lodgepole Pine Posts and Poles Three studies on the processing and preservation of dead lodge pole pine posts and poles indicated that some care is necessary in selecting material to be treated with a preservative. Machine peeled dead tree posts were somewhat rougher than peeled green tree posts and had a slight tendency to be stopped in the peeling machine. The steeping method of preservative treatment gave inconsistent retentions for the study times used, and none of these posts or poles met the retention specified. Poles treated by the hot and cold bath nonpressure method and posts treated by the pressure method had retentions exceeding the minimum specification require ments. The low moisture content of the dead posts and poles eliminated the necessity for air-drying them before treatment and reduced the time needed to get the minimum retention required.
