Distribution of tlie Black Locust. it very desirable for fence posts, rail- road ties, insulator pins, and many other similar articles. In common with many other legumes, its widely spreading and shal- low roots harbor nitrogen-fixing bac- teria ; and it is said that barren sand planted to Black Locust will become fit, in T) years, to support bluegrass. The use of the tree is advocated also for holding and reclaiming badly gullied lands, and its rapid growth makes it a suitable tree for planting on the "spoil banks" of strip mines, wherever there is any quantity of limestone. The usefulness of the Black Lo- cust is, however, very greatly limited by the fact that it is subject to great damage from an insect known as the Loctist Borer, which is particularly destructive in piu'e stands situated on poor soils. ACER Linnaeus The Maples Family Aceraceae Small to very large, deciduous trees, with opposite, simple, palmately lobed, or (in one species) compound, petiolate leaves and regular flowers growing in fascicles or racemes from lateral or terminal flower-buds, the pistils and stamens usually in separate flowers. Fruit, known commonly as maple "keys," a pair of seeds, each with a long, narrow, membranous wing. Twigs round or 6-sided, with round, pale pith and oval or coni- cal buds sessile or on stalks above more or less U-shaped leaf-scars. Bark quite varied in appearance and characteristics. With nearly lOU species, Acer is at home through almost all of the Northern Henfisphere, and one species, in the mountains of Java, crosses to the south of the Equator. Abundant and varied as the Maples are today, during ancient geological times they were still more numerous and varied in their forms. In the history of man. Chaldea. Assyria, and Babylon, Egypt, Greece, and Rome have risen and fallen, but the heyday. Please note that these images are extr
