Acer saccharinum, Wang.^*

One of the largest of the maples. In the colder latitudes of North America, 80 feet high. Wood of rosy tinge, when knotty or curly furnishes the Birdseye and curly Maplewood. In the depth of winter the trees, when tapped, will yield the saccharine fluid, which is so extensively converted into maple sugar, each tree yielding 2 to 4 lb. a year. The trees can be tapped for very many years in succession, without injury. The Sugar Maple is rich in potash. Numerous other maples exist, among which as the tallest may be mentioned, Acer Creticum, L., of South Europe. 40 feet; A. Iævigalum, A. sterculiaceum and A. villosam, Wallich, of Nepal, 50 feet; A. pictum, Thunb., of Japan, 80 feet.
