Extract

During the summer months, dead and weakened trees and logs left in the woods are subject to attack by a variety of insects, mainly of the order Coleoptera. Some are wood-boring forms which cause a depreciation in the potential value of the lumber; others are barkbeetles which at times may build up in numbers sufficient to cause a primary attack on the living stand.
