Fig. 4.—Trunk of tree, show-ing paper band. (Original.) THE CANKER-WORM attempts to pass over it. Either of these substances will remainfor two or three months in a sticky condition. To preventcanker-worm injury, an application early in March, and an-other the first of September will probably suffice. It hassometimes been recommended to smear raupenleim and den-drolene directly upon the bark of the tree, but recent experi-ence has shown that there is danger of thus injuring the treethrough the absorption of the materials of which the applica-tion is composed. It is probably worth while to take a little i
