  • Interesting fact: The "Spruce Goose" flew on November 2, 1947, for one mile, at a maximum altitude of 70 feet. Built by Howard Hughes, it is the largest aircraft ever built, the 140-ton eight-engine seaplane, made of birch, has a wingspan of 320 feet. It was built as a prototype troop transport. Rejected by the Pentagon, Hughes put the plane into storage, never to be flown again.

    • n birch A tree or shrub belonging to the genus Betula (which see). The birches have smooth, laminated outer bark and close-grained wood, which in some species is hard and tough, taking a fine polish, and is used in the manufacture of furniture and for many other purposes. The white, gray, or poplar birch, Betula alba, the principal European species, is a small tree, but is put to many uses, especially in the old world. The bark is used for tanning and thatching, and yields an oil which is said to be used to give Russia leather its peculiar odor; spruce-oil is also used for this purpose. The leaves, as well as the sap and oil, are used in the treatment of various chronic diseases, and the wood is used for fuel and many other purposes. Several varieties of this species, as the weeping, cut-leafed, and purple birches, are much cultivated for ornament. The canoe- or paper-birch of North America, B. papyrifera, is a large tree with a very tough, durable bark, which is largely used by the Indians in the manufacture of canoes and tents. The timber is valuable. The yellow or gray birch, B. lutea, is one of the most important deciduous trees of the northern Atlantic forests, growing to a very large size; its wood is heavy, very strong, aud hard. The black, sweet, cherry-, or mahogany-birch, B. lenta, has a very spicy, aromatic bark, yielding a volatile oil identical with oil of winter-green, and its heavy, dark-colored wood is largely used for making furniture and in ship-building. Other prominent species are the red or river-birch, B. nigra, of the Southern States, and the black birch, B. occidentalis, of the Rocky Mountains aud westward. Several shrubby species are widely distributed in mountainous and arctic regions, reaching a higher latitude than any other deciduous tree, as the alpine birch (B. nana), the low or dwarf birch (B. pumila), aud the scrub birch (B. glandulosa).
