The young leaves are rose colored when they unfold, and when full grown are six inches wide. The wood is light and soft, and light brown in color, the thick sapwood lighter. The wood is liable to contain small brown pith flecks, which in longitudinal sections appear as brown streaks an inch or less in length and as thick as a pin, and in cross section they are brown dots. They are not natural to the wood but are caused by the larvæ of certain moths which burrow into the cambium layer, or soft inner bark, and excavate narrow galleries up and down the trunk. The galleries afterwards fill with dark material. The insects sometimes attack other maples, the birches, service, and other trees. The wood of striped maple is little used, because of the small size of the trees. The species is planted for ornament in this country and Europe. BLACK MAPLE (_Acer nigrum_) has been by some considered a variety of sugar or hard maple, and by others a separate species. It is as large as the sugar maple and its range is much the same, but it is more abundant in the western part of its range than in the East. The name refers to the color of the bark of old trunks. If the name had considered the bark of young twigs it would have been yellow or orange maple, because the twigs are of that color. In summer the peculiar drooping posture of the leaves calls attention to this tree. However, the bark, twigs, and leaves combined are not sufficient to set it apart, in the eyes of most people, for it generally passes without question as sugar maple, even when it stands side by side with that tree. It yields sugar abundantly. The wood is a little heavier than that of sugar maple, but the difference cannot be noticed except when the two woods are weighed. Their uses are the same. No maker of furniture, flooring, or finish ever protests against black maple. The tree generally prefers lower and damper ground than sugar maple, and is often found along streams. [Illustration] SERVICEBERRY [Illustration: SERVICEBERRY] SERVICEBERRY (_Amelanchier Canadensis_) This tree will never be other than a minor species in the United States, but it is not a worthless member of the forest. It belongs to the rose family, and therefore is near akin to the haws, thorns, and crabapples. The genus is found in Europe, Asia, and Africa, as well as in the United States. Two tree species occur in this country, or, according to some botanists, three, one west of the Rocky Mountains, two east.
