So is the apple-tree, even when full grown, within the reach of children. It can be climbed. Little swings are hung from the branches. Its shade is low and familiar. It bestows its fruit liberally to all alike. The apple is a sturdy tree. Short of trunk and short of continuous limb, it is yet a stout and rugged object, the indirectness of its branching branches adding to its picturesque quality. It is a tree of good structure. Although its limbs eventually arch to the ground, if left to themselves, they yet have great strength. The angularity of the branching, the frequent forking, the big healing or hollow knots with rounding callus-lips, give the tree character. Anywhere it would be a marked tree, unlike any other. The bark on the older surface sheds in short oblong irregular scales or plates that detach perhaps at both ends and often at the sides, clinging by the middle until the curl loosens them and they fall to the ground. These plates or chips are more or less rowed up and down the trunk and on the larger branches, yet the apple bark is not ridged and furrowed as on the elm. The bark is not checked in squares as on old pear-trees nor peeling as on cherries. In dry weather, the loose old bark is dark brown-gray, often supporting gray lichens, but in rain it is soft and nearly black, yielding pleasantly to the touch. In the forks, the bark is not so readily cast and there the chips may lie in heaps. On the young limbs and small trunks the bark is tight and close, not splitting into seams or furrows with the expansion of the cylinder but stretching and throwing off detached flakes and chips. Under the chips various insects hide or make some of their transformations. There the codlin-moth pupates. The old remains of scale insects may be found on the exterior. In the furrows about the dormant buds the eggs of plant-lice pass the winter. To destroy these breeding and hiding places, many careful apple-growers scrape away the loose bark, being careful not to expose the quick living tissue; and on the younger wood the eggs of aphis and other pests, as well as cocoons and nymphs, are destroyed by vigorous winter spraying. The regular spraying of apple-trees, in the different seasons, more or less sterilizes the bark. Many forms of canker, due to fungi and bacteria, invade the bark, making sunken areas and scars, often so serious as to destroy the tree. All these features are discoverable in the apple-tree. The trunk of the apple-tree is short and stout, usually not perfectly cylindrical and not prominently buttressed at the base. In old trees it is usually ribbed or ridged, sometimes tortuous with spiral-like grooves, often showing the bulge where the graft was set. The wood is fine-grained and of good color, and lends itself well to certain kinds of cabinet work and to the turning-lathe for household objects; it should be better known. [Illustration: 2.
