SELECTION OF FURNITURE 253 Tupelo and black gum are also called gums but are not botani- cally related to the gum. They are harder and heavier than red gum and in color range from white to grayish brown. They are almost identical, but the tupelo is considered superior. Black gum has a ribbon stripe when quartered. These gums are used for kitchen furniture and for hidden parts of furniture. Birch. Birch is considered one of the strongest furniture woods. It takes and retains finish well over its fine grain, and it can be made to imitate costlier woods. It is combined with other woods for strength in plywood and is also used in the construction of early provincial pieces and bentwood. Ash. White, green, and black ash all have white sapwood. The heartwood of white and green ash is light grayish brown; that of black ash is darker. Ash is desirable furniture wood as it has a nice grain, is fairly strong and hard, is easily worked, bends well, and does not warp. Other American Hardwoods. Beech is a plain, strong wood. Chestnut resembles oak and is used for outdoor and simple indoor furniture. Cherry is strong and beautiful in grain and color but is very scarce. Elm is a durable plain wood. Holly is a hard white wood used for inlays. Hickory is remarkably strong, tough, and elastic. However, hickory shrinks and is attacked by bor- ing insects; pecan is the most popular of the hickory group. Sycamore is used for concealed parts of furniture mostly, although it has grain. Cottonwood is soft and uniform in texture. American Softwoods. Softwoods comprise less than 10 per cent of the furniture woods in the United States. They are espe- cially valuable because of their flexibility. Western fir, spruce, hemlock, red cedar, pine, white pine, and redwood are employed. Southern yellow pine is used for common furniture. Eastern red cedar is used largely for chests, because of its fragrance and its resistance to moth larvae. Imported Hardwoods. True mahogany is the best known of the imported woods. It comes from the. West Indies and Central and South America. The preferable finish for mahogany is now lighter and reveals the grain of the wood; a dark reddish opaque finish is fortunately unfashionable. Other imported hard woods are primavera, tanguile, lauan, rosewood, satinwood, and ebony,
