Impact of Naval Stores on Utilization of Longleaf and Slash Pine Timber

Crude oleoresin in the amount of 500,000 barrels, or 82 percent of the U.S. output, was produced in Georgia in 1960. Increased production is projected but amounts are un predictable. Current use of acid and improved bark chipping does not seriously impair the tree for use as lumber, pulp, or poles. Yields of pulp were found to be approximately equal in roundwood with worked and unworked faces. Seasoning long leaf pine to 30 percent moisture content permitted adequate penetration of preservative during pressure treatment of poles with worked faces. Incising gave insurance of preservative penetration. Sawlogs are frequently long-butted; some saw mill operators believed butt logs with worked faces were objectionable. A 5-year study showed income from gum males much higher than any decrease in growth rate of wood and mortality of worked out trees was less than 1/3 of 1 percent.
