If the tree has been lacerated to some extent, a plaster of moistened clay or cow-manure makes a good salve. Keeping the borers out of the tree is far better than taking them out; and this can be effected by wrapping the stem at the ground two inches below the surface, and five above with strong hardware or sheathing paper.
But since then much attention has been paid to shade, both as to quantity and kind, and the Borer may now be regarded as an insect which can with certainty be held in check if the land is properly shaded with good caste trees. And I say good caste trees, because bad caste trees encourage Borers, and Mr.
They can not do much harm, unless a tree is neglected; in this case, however, they will soon enfeeble, and probably destroy it. When once within a tree, borers must be cut out with a sharp- pointed knife, carefully yet thoroughly. The wounds from the knife may be severe, but the ceaseless gnawing of the grub is fatal.
A few poor flints were found and a little pottery, together with many bones of animals and some pins and borers of bone. The most important find made, however, was a small conical button made of bone with two holes pierced in its flat side and meeting in the middle.
Accordingly the drills and hammers were all taken up, and they were soon at work. Two or three gentle taps were given to the borers, to make them stand upright, and then all four began work. At first they often either missed the heads of the borers or struck them unevenly.
The downy woodpecker bores his nest hole in the softened heart-wood of upright limbs and pays for his lodging by devouring all grubs and borers that otherwise might make his house fall too soon. The bluebird finds his dwelling ready made, lower down, often in a horizontal limb, having neither strength nor inclination to bore for himself.
Most people who have made the acquaintance of our common birds know the friendly little Chickadee, which winter and summer is a constant resident in groves of deciduous trees. It feeds, among other things, on borers living in the bark of trees, on plant lice which suck the sap, on caterpillars which consume the leaves, and on codling worms which destroy fruit.
A great saving of the forests may be effected by what is called preservative treatment, which consists of treating railroad ties, piling, mine timbers, poles, and posts with creosote or zinc chlorid to prevent decay from the moisture of the ground or from injury by salt-water borers. The use of creosote is almost double the cost of zinc chlorid, but it is much more effective and durable.
The insects which injure the hardwood forest trees are principally the leaf-eaters, such as the gypsy and brown tail moths, which have almost stripped the New England shade trees, and done great damage to the forests; the elm leaf beetles and the numerous borers, both beetles and grubs, which from eggs laid in or just beneath the bark, hatch into larvæ which burrow into the wood, destroying its usefulness for lumber.
The Commentary on Shakespeare of Gervinus, a really superior man, reminds one of the Roman Campagna, penetrated underground in all directions by strange winding caverns, the work of human borers in search of we know not what.
