ASPEN LSAF,ASPE/* POPLAPoaPOPPLL UiK Quaking Asp, Quiver Leaf, Aspen Poplar or Popple. {Populus tremuloides) A small forest tree, but occasionally loo feet high. Readily known by its smooth bark, of a light green or whitish color. The wood is pale, soft, close-grained, weak, perishable, and light. A cubic foot weighs 25 lbs. Good only for paper pulp, but burns well, when seasoned. When green it is so heavy and soggy that it lasts for days as a fire check or back-log. Leaves I5 to 2 inches long. A tea of the bark is a good substitute for quinine, as tonic, cold cure, bowel cure and fever driver.
