The air must be remarkably still if the foliage is not quaking or trembling. The leaves are simple, alternate, ll/2 to 2^ inches long, nearly round, finely toothed on margin, with leaf-stalks flat- tened laterally. The flowers ap- pear early in the spring.

The air must be remarkably still if the foliage is not quaking or trembling. The leaves are simple, alternate, ll/2 to 2^ inches long, nearly round, finely toothed on margin, with leaf-stalks flat- tened laterally. The flowers ap- pear early in the spring. Pollen- bearing and seed- producing occur on different trees. Both are arranged in slender droop- ing tassels. The fruit is a 2- valved capsule con- taining small seeds with tufts of fine hairs. The bark is white or grayish to yellowish- green; on old trunks becomes rough and black. The twigs are smooth, shiny, reddish-b r o w n. The buds are narrow, conical, sharp-pointed, smooth, shiny, appear varnished, covered with 6 to 7 reddish-brown scales. The wood is soft, weak, not durable, fine in texture, white to light brown. It is used for paper pulp, boxes, crates, and wooden dishes. The Quaking Aspen is the most widely distributed tree in North America. It is a transcontinental tree extending from Newfoundland to Alaska and south to New Jersey, Ken- tucky, Mexico, and California. This tree is common in most sections of New York, but is rare on calcareous soils and infrequent in the pine barrens of Long Island. Closely related to the Quaking Aspen and widely dis- tributed in New York is the Large-toothed Aspen (Populus grandidentata). The leaves of the latter are larger and more coarsely toothed, and its buds are stout, broad-pointed and covered with a flour-like QUAKING ASPEN One-fourth natural size, except enlarged flowers and Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Illick, Joseph S.
