Among the resinous trees of the United States, the _White Cedar_ is one of the most interesting for the varied utility of its wood. North of the river Connecticut, it is rare and little employed in the arts. In the southern states, it is not met with beyond the river Santee, but it is found, though not abundantly, on the Savannah: it is multiplied only within these limits and to the distance of fifty miles from the ocean. The white cedar is seventy or eighty feet high, and sometimes more than three feet in diameter. When the trees are close and compressed, the trunk is straight, perpendicular and destitute of branches to the height of fifty or sixty feet. When cut, a yellow transparent resin of an agreeable odor exudes, of which a few ounces could hardly be collected in a summer from a tree of three feet in circumference. The foliage is evergreen: each leaf is a little branch numerously subdivided, and composed of small, acute, imbricated scales. The _White Ash_ is one of the most interesting among the American species for the qualities of its wood, and the most remarkable for the rapidity of its growth and for the beauty of its foliage. A cold climate seems most congenial to its nature. It is everywhere called _White Ash_, probably from the color of its bark, by which it is easily distinguished. The situations most favorable to this tree are the banks of rivers and the edges and surrounding acclivities of swamps. The white ash sometimes attains the height of eighty feet, with a diameter of three feet, and is one of the largest trees of the United States. The trunk is perfectly straight and often undivided to the height of more than forty feet. On large stocks the bark is deeply furrowed, and divided into small squares from one to three inches in diameter. The leaves are twelve or fourteen inches long, opposite and composed of three or four pair of leaflets surmounted by an odd one. The leaflets are three or four inches long, about two inches broad, of a delicate texture and an undulated surface. Early in the spring they are covered with a light down, which gradually disappears, and at the approach of summer they are perfectly smooth, of a light green color above and whitish beneath. It puts forth white or greenish flowers in the month of May, which are succeeded by seeds that are eighteen lines long, cylindrical near the base, and gradually flattened into a wing, the extremity of which is slightly notched. They are united in bunches four or five inches long, and are ripe in the beginning of autumn. The shoots of the two preceding years are of a bluish gray color and perfectly smooth: the distance between their buds sufficiently proves the vigor of their growth.
