. Our native trees and how to identify them; a popular study of their habits and their peculiarities. Trees. LAUREL FAMILY Stamens.—In sterile flowers nine, inserted on the base of the calyx in three rows, the inner row with a pair of conspicuous glands at the base of each; fertile flowers have six short rudimentary stamens. Anthers innate, oblong, four-celled, opening by four up- lifting valves. Pistil.—Ovary superior, nearly sessile in the tube of the calyx, simple, one-celled ; style one ; ovule one, suspended from the apex of the cell. Fruit.—Drupe, oblong, dark blue, shining, surrounded at the base by the enlarged and thickened scarlet calyx raised on a club- shaped rather fleshy pedicel. Cotyledons thick, fleshy. The Sassafras often grows in dense thickets. A single tree, if allowed to spread unrestrained, will soon be surrounded by a numerous and flourishing family, as its stoloniferous roots extend in every direction and send up multitudes of shoots. When full grovirn it is rather picturesque, as its branches are usually irregular and the head partially flattened, It has the peculiarity of looking older than it really is because of its rough, deeply furrowed, gray bark and rather warped stem. This cracking of the bark is characteristic, it begins on stems two or three years old, and continues through life. A peculiar foliage marks the tree in every situation, for it enjoys the distinction of bearing leaves of three different forms on the same branch ; a distinction among our common de- ciduous trees shared only with the Mulberry. Those leaves are oval, or oval with a lobe at one side making what are called "mittens, " or regu- larly three-lobed. There seems to be no known law which determines the order of their appearance, but the mature tree bears more oval leaves ' than lobed ones. The Sassafras will grow in any loose moist soil, and es- pecially delights in neglected and abandoned fields. The fruit is a beautiful, dark blue, shining berry s
