On the bottomlands, the Sweet Gum is commonly associated with Sycamore, Cottonwood, Honey Locust, the bottomland oaks. Pecan, Hack- berry, and Soft Maple. Uses: The heavy and close-grained wood of the Sweet (jum, though hard, is not very strong; but because of its fine texture and the alternating streaks of red and black, which give highly figured patterns, it is used often for interior finishing, especially in the panels of doors and walls. To some extent, it is used in the manufacture of furniture, as a sul)sti- tute for walnut or mahogany, being, indeed. ex])orted to England under the trade name "satin ; A "sweet gum" derived from the tree is similar, in its properties and com])osition. to the storax taken from Licjitidaiiibar oricntalis in Asia Minor, a substance yieldin;^ both cinnamic acid and cinnamic alcohol.
