“ The wood is very compact and fine-grained—the heart-wood being reddish, and, when cut into planks, marked transversely with blackish belts. It is employed for veneering in America. Being readily dyed black, it is sometimes used instead of ebony for picture frames, balusters, &c.; but it is too liable to decay for outdoor work. The gum resin yielded by this tree has no special medicinal virtues, being inferior in therapeutic properties to many others of its class. ”
