. Our native trees and how to identify them; a popular study of their habits and their peculiarities. Trees. BIRCH FAMILY grown are dull dark green above, pale yellow green below ; midrib yellow, primary veins indistinct above but conspicuous and hairy below. In autumn they turn a clear bright yel- low. Petioles stout, hairy, deeply grooved above. Stipules ovate, pale green or nearly white, caducous. Flowers.—April, before the leaves. Stami- nate catkins form in late summer, during winter are three-fourths of an inch long. When the flowers open the catkins become three to four inches long, and in general appearance become bright yellow due to the abundant anthers. Scales ovate, bright red brown above the mid- dle, pale brown below. Pistillate catkins from one-half to three-fourths of an inch long, scales Sweet Birch, Srf, , /./™;.. ovate, pale green; styles exserted, slender, Strobiles erect, i' to P^'^ pmk. iK' long. Fruit.—Strobiles oblong-ovoid, smooth, ses- sile, erect, one to one and one-half inches long, one-half an inch thick. Scales smooth, with rounded or acute lat- eral lobes. Nut obovate, pointed at base, about as broad as its wing. The Black Birch which is a handsome tree with its tall dark stem, graceful fragrant branches and dark green foliage, is especially beautiful in early spring when its long staminate catkins hang from the leafless branches changing them for a few days into fountains of golden spray and making it the most conspicu- ous of the American birches. —Charles S. Sargent. The names White, Black, and Yellow are often given to trees with very little justification, but in the case of the birches they express differences which are apparent to the most casual observer. The trunk of the White Birch is really white, the bark of the Yellow Birch is indeed yellow and that of the Black Birch is so dark that it may easily be considered black. The bark resembles in general appearance that of the common cherry tree, whence the name Cherry Birch
