. North American trees : being descriptions and illustrations of the trees growing independently of cultivation in North America, north of Mexico and the West Indies . Trees. American Arbor-Vitae 95 Tennessee. Its maximum height is 22 meters, with a trunk diameter of meters. Sometimes, however, it is only a shrub. The trunk is often fluted and much buttressed at the base, and frequently divided into several smaller upright trunks. The branches are horizontal, short, more or less curved upward toward the ends, forming a dense, narrow, cone- shaped tree. The bark is about 6 mm. thick, shallowly fissured into long, narrow ridges, which peel off into long fibrous persistent shreds of a light yellowish or reddish brown color. The twigs are flattened, somewhat 4-sided, sometimes zig- zag, light yellowish green, changing to light reddish brown, and finally darker brown, and become round and marked by the scars of the fallen lateral twigs, which are pendulous and fall away after having become about i dm. long. The leaves are yellowish green, scale-Uke, ovate to lanceolate, 6 mm. long, sharply pointed at the apex, and glandular on the back, on the larger twigs; on the lateral twigs they are much smaller, scarcely glandular, the lateral rows much keeled, the others flattened, giving the twigs a very flat appearance. The flowers, appearing from April to June, are about mm. long, and pinkish. The cones ripen in the au- timm, and shed their seed, but persist dur- ing the winter; they are oblong, 8 to 12 mm. long. The scales are leathery, oblong, blunt-pointed, or minutely tipped, the inner having 2 seeds, the outer often but i seed or none. The seeds are oblong, about 6 mm. long; their wings about as wide as the body, appearing notched at the apex. The wood is soft, brittle, rather coarse- grained, light yellowish brown, and fra^ grant; its specific gravity is about It is very durable, and is largely used at the North for railroad ties, fence-posts, and shingles.
