. 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. Bull Pine 25 3 faces, containing 2 to 5 resin-ducts and 2 fibrovascular bundles. They form large tufts at the ends of the otherwise naked twigs and persist for about three years. The staminate flowers are short, crowded, cyhndric and usually curved,from 4 to 5 cm. long, their anthers yellow'. The pistillate flowers are almost terminal, nearly globose, 8 mm. long, dark reddish, their scales oval and gradually narrowed to slender elongated tips; the conspicuous bracts are orbicular and fringed. The cones are fully grown by midsummer of the second season, when they are horizontal or slightly incHned, short-stalked or nearly sessile, oval, to 15 cm. long, often in clusters of 3 to 5, usually falling off early, and in doing so break away from their base, leaving a few of the lower scales attached to the short persistent peduncle. The scales are rather thin and narrow, concave, usually rounded and transversely keeled, and terminated by a raised knob and a straight or recurved slender spine; the exposed portion is light reddish brown and shining, otherwise they are dull red- dish brown above, purphsh beneath; seed ovoid, 6 mm. long, compressed, sharp- pointed, rounded at the base, dark purphsh and mottled; wing narrow, four times longer than the body and 6 mm. wide; cotyledons 6 to 9. The wood is hard, strong, but brittle, ^lose-grained, hght reddish and very resinous in conspicuous bands; its specific gravity is about It is not durable in contact with the soil, but is largely used for construction work, fencing, railroad ties, fuel, and lumber. The fiber extracted from the leaves of the variety Benthamiana of southern Oregon is used for medicated pillows and rugs; a volatile oil is also distilled from the leaves and used medicinally. The soft sapwood was used by the Indians for food in time
