Agricultural Experiment Station; Agriculture -- New York (State). Rural School Leaflet 1357 ASPEN The American aspen, also known as quaking aspen, trembling aspen, popple aspen, and small-toothed aspen, may be distinguished by the roimd or ovate leaves, which have finely saw-toothed margins and short points. The aspen is more conspicuous in simimer, when the constant treinbling motion of its leaves attracts the attention, than it is in winter, although in some individual trees the smooth, green bark of the trunk is very attractive in contrast with the snow. The large-toothed aspen may be distinguished by its coarsely wavy-toothed leaves, which are larger than those of the American aspen, which it re- sembles. (See illustration.) Both species are ver>' common throughout New York State, especially on abandoned fields, on land from which the trees have been cut, and on burned areas. The aspen reproduces very easily from seed, and often it is the first tree to spring up after a woodlot has been cut over. It grows rapidly and is short lived, but is of value because it covers the soil rapidly and acts as a temporary shelter for more valuable trees while they are young. The wood is from light brown to white in color and is neither strong nor dur- able. It is the first wood that was used in making paper pulp. It is used, also, for buckets, pails, kegs, wooden dishes, and boxes..
