. 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. Pond Pine 31 yellow, finally dark grayish brown, and roughened by the persistent bases of the bud-scales; branch-buds ovoid or ovoid-oblong, narrowed and sharp at the tip, the scales loose, dark brown, and shining. Leaves in sheathed fascicles of 3, bright green, rather stout and stifif, 6 to 12 cm. long, closely and sharply toothed and tapering to a thick tip, the stomata sunken, in many rows on all 3 faces, contain- ing 3 to 7 resin-ducts and 2 fibrovascular bun- dles; they are in rather spreading tufts and per- sist for two or three years. The flowers appear in the spring; the staminate, in short crowded clusters, are cylindric, to cm. long, anthers yellow. The pistillate flowers are lateral, more or less clustered, short-stalked, subglobose, about 4 mm. long, the scales light green with a reddish tint at the contracted, slightly spreading tip. The cones, which reach maturity by the second autumn, are nearly sessile, ovoid to globose, 4 to 7 cm. long, light brown, opening and shedding their seed during the autumn and winter, usually persisting on the branches for ten or more years. The scales are thin and flat, prominently ridged with a dark knob and armed with a stiff recurved prickle on the exposed end, reddish on the unexposed surfaces; seed somewhat angled, oblong, 4 to 6 mm. long; wing about 8 mm. long; cotyledons 4 to 6. The wood is soft, weak, coarse-grained and resinous^ bright brown or reddish with broad resin bands; its specific gravity is about It is quite durable; sometimes sawn into lumber and also used for railroad ties, construction timbers, fuel, and charcoal. It was formerly one of the chief sources of turpentine, but has been superseded by the more productive Long-leaf pine. Its adaptabiUty to poor soils and its rapid growth thereon make this a most valualale
