S. P. Ahies canadensis Miller. Picea alba (Aiton) Link Also called Single spruce, Skunk spruce, Cat spruce, Double spruce, and locally known as Spruce and Pine, this extends across the entire northern portion of the continent, if the western tree is, as sup- posed to be, identical with the eastern, from New- foundland and Labrador to Alaska; eastwardly its southern limits are in South Dakota, penin- sular Michigan to northern New York, reaching the Atlantic coast in southern Maine. It attains its greatest development in northern British America, a maximum height of about 35 meters with a trunk diameter of i meter. In its eastern range, however, it seldom reaches half these dimensions. It prefers moist hillsides or the borders of rivers or swamps. The branches are long, stout, and upwardly curved, their branchlets stout, sti£f, and pendu- lous. The bark is 6 to 12 mm. thick and broken intg irregular scaly plates which sepa- rate easily and are light brownish gray. The twigs are nearly smooth, grayish green becoming orange-brown and finally dark grayish brown. The winter buds are broadly ovoid and blunt, from 3 to 6 mm. long, their scales light brown and fringed. The leaves, which sometimes have a pronounced polecat odor, are 4-sided, i to 2 cm. long,
