=88. Live Oak= (_Quercus chrysolepis_) (Maul Oak, Valparaiso Oak). Medium- to small-sized tree. California. OSAGE ORANGE =89. Osage Orange= (_Maclura aurantiaca_) (Bois d'Arc). A small-sized tree of fairly rapid growth. Wood very heavy, exceedingly hard, strong, not tough, of moderately coarse texture, and very durable and elastic. Sapwood yellow, heartwood brown on the end face, yellow on the longitudinal faces, soon turning grayish brown if exposed. It shrinks considerably in drying, but once dry it stands unusually well. Much used for wheel stock, and wagon framing; it is easily split, so is unfit for wheel hubs, but is very suitable for wheel spokes. It is considered one of the timbers likely to supply the place of black locust for insulator pins on telegraph poles. Seems too little appreciated; it is well suited for turned ware and especially for woodcarving. Used for spokes, insulator pins, posts, railway ties, wagon framing, turnery, and woodcarving. Scattered through the rich bottoms of Arkansas and Texas. PAPAW =90. Papaw= (_Asimina triloba_) (Custard Apple). Small-sized tree, often only a shrub, Heartwood pale, yellowish green, sapwood lighter color. Wood light, soft, coarse-grained, and spongy. Not used to any extent in manufacture. Occurs in eastern and central Pennsylvania, west as far as Michigan and Kansas, and south to Florida and Texas. Often forming dense thickets in the lowlands bordering the Mississippi River. PERSIMMON =91. Persimmon= (_Diospyros Virginiana_). Small to medium-sized tree. Wood very heavy, and hard, strong and tough; resembles hickory, but is of finer texture and elastic, but liable to split in working. The broad sapwood cream color, the heartwood brown, sometimes almost black. The persimmon is the Virginia date plum, a tree of 30 to 50 feet high, and 18 to 20 inches in diameter; it is noted chiefly for its fruit, but it produces a wood of considerable value. Used in turnery, for wood engraving, shuttles, bobbins, plane stock, shoe lasts, and largely as a substitute for box (_Buxus sempervirens_)--especially the black or Mexican variety,--also used for pocket rules and drawing scales, for flutes and other wind instruments. Common, and best developed in the lower Ohio Valley, but occurs from New York to Texas and Missouri. POPLAR (See also Tulip Wood) Wood light, very soft, not strong, of fine texture, and whitish, grayish to yellowish color, usually with a satiny luster. The wood shrinks moderately (some cross-grained forms warp excessively), but checks very little in seasoning; is easily worked, but is not durable. Used in cooperage, for building and furniture lumber, for crates and boxes (especially cracker boxes), for woodenware, and paper pulp.
