Saplings
Saplings, including hickory and other round hoop-poles and similiar products, are subject to serious injuries and destruction by round- and flat-headed borers ([Fig. 24]), and certain species of powder post borers ([Figs. 26] and [27]) before the bark and wood are dead or dry, and also by other powder post borers ([Fig. 28]) after they are dried and seasoned. The conditions favoring attack by the former class are those resulting from leaving the poles in piles or bundles in or near the forest for a few weeks during the season of insect activity, and by the latter from leaving them stored in one place for several months.
