. 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. Sugar Pine most other conifers, it does not thrive in the smoky air of dense cities. The name Weymouth pine was given to the tree in England, because it was planted by Lord Weymouth in Wiltshire, early in the eighteenth century; it is also called Soft pine and Northern pine. 2. WESTERN WHITE PINE —Pinus montdcola Douglas This pine very closely resembles the eastern white pine, and was regarded as a variety of it by Nuttall, but its differences from that species appear to be constant. It reaches a maximum height of about 50 meters, with a trunk sometimes nearly 3 meters thick, and occurs from northern Montana to southern British Columbia, southward to the moimtains of south-central CaUfomia. The thick bark of old trees is fissured into nearly square plates; that of young trees is gray, smooth, or nearly so. The young twigs are stout and brown-hairy, becoming smooth and reddish. The leaves are 5 in each sheath, stout and stiff, bluish green, 10 cm. long or less, their sheaths loose, i to 2 cm. long, early falling away. The staminate flowers are numerous, borne on the sides of shoots of the season, i cm. long or less; the pistillate flowers are terminal and stalked. The ripe cones are to dm. long, and 4 to 5 cm. thick, thus much larger than those of Pinus Strobus; they are pendulous, pointed, and their scales open to shed the seeds in the summer or autumn of the second sea- son; the cones fall away from the tree in the following winter or spring; the scales are slightly thickened near the tip, otherwise thin, short-pointed, without any spine or^rickle; the seeds are about cm. long, the thin wing three or four times as long as the oblong body. The tree is of slower growth than its eastern relative; its wood is nearly white, soft and easily worked, has a specific gravity of about
