The _Hemlock Spruce_ inhabits a similar tract of country, though moist ground appears not to be the most favorable to its growth. It arrives at the height of seventy or eighty feet, with a circumference of six or nine feet, and is uniform for two thirds of its length. The _White_ and _Black Spruce_ are varieties of this genus. _Cypresses._――The _Cypress_ is a very interesting tree, from its extraordinary dimensions, and the varied application of its wood. Its northern boundary is Indian river, in Delaware, in latitude about thirty-nine degrees. In proceeding southward, it becomes more abundant in the swamps, and in Louisiana those parts of the marshes where the cypress grows almost alone are called cypress swamps, and they sometimes occupy thousands of acres. In the swamps of the southern states and the Floridas, on whose deep, miry soil a new layer of vegetable mould is every year deposited by floods, the cypress attains its utmost developement. The largest stocks are one hundred and twenty feet in height, and from twenty-five to forty feet in circumference, above the conical base, which at the surface of the earth is three or four times as large as the continued diameter of the trunk: in felling them, the negroes are obliged to raise themselves upon scaffolds five or six feet from the ground. The base is usually hollow for three fourths of its bulk. Amidst the pine forests and savannas of the Floridas is seen here and there a bog filled with cypresses, whose squalid appearance, when they exceed eighteen or twenty feet in height, proves how much they are affected by the barrenness of a soil which differs from the surrounding only by a layer of vegetable mould, a little thicker upon the quartzous sand. The summit of the cypress is not pyramidical like that of the spruce, but is widely spread and even depressed upon old trees. The foliage is open, light, and of a fresh agreeable tint; each leaf is four or five inches long, and consists of two parallel rows of leaflets upon a common stem. The leaflets are small, fine, and somewhat arching, with the convex side outwards. In autumn they change from a light green to a dull red, and are shed soon after. This tree blooms in Carolina about the first of February.
