A Better Way of Woodcutting Logger / Inventor Joseph Buford Cox was chopping firewood one autumn day in 1946 when he paused to examine curious activity in a tree stump. A timber-beetle larva, the size of a man's forefinger, was easily chewing its way through sound timber, going both across and with the wood grain at will. Joe was an experienced operator of the gas-powered saws used in those days, but the cutting chain was a problem. It required a lot of filing and maintenance time. "I spent several months looking for nature's answer to the problem." Joe recalled. 'I found it in the larva of the timber-beetle."
