Red Spruce
RED SPRUCE
(Picea rubra)
Shape loosely pyramidal; 40-75 ft. tall. Trunk slender. Bark reddish brown, flaky with thin scales. Branches ascending near the top of the tree, the lower down sweeping. Needles fragrant, 4-angled, scarcely more than ½ in. long. Cones 1½-2 in. long, clustered near the summit. Range: Marit. Provs. of Can., N.E., N.Y., s. on the mts. to Pa., and highest peaks of Va. and N. C. Employed for construction, pulp, and flooring, this is also considered the best American wood for resounding boards of musical instruments. WHITE SPRUCE (Picea canadensis) ranges from Labr. to Alaska, s. to N.E., centr. parts of Mich. and Wis., the Black Hills. w. slopes of the Rockies in Can. and Mont. Not a large or valuable tree except for paper pulp, it is the most ornamental eastern spruce. It differs in its smooth twigs and longer cones: the needles are unpleasantly scented.
Black Spruce
BLACK SPRUCE
(Picea mariana)
Shape very narrow, spire-like; 20-90 ft. tall or sometimes a knee-high dwarf even when very old, on the muskeags of the Northwest. Bark grayish brown, flaky, thin-scaly. Branches very short, horizontal or a little down sweeping, lightly up curving at the tips. Needles bluish green with a whitish bloom, ½-¾ in. long, 4-angled. Cones ½-1½ in. long; scales stiff and thin. Range: Throughout the forest belt of Can., except the Rockies, s. to Pa. and thence on the high mts. to N.C., centr. parts of Mich., Wis., Minn. Individually beautiful, this becomes a monotonous and somber tree through the northern interior of the continent. The wood is not useful except for paper pulp, but in that form it is employed by almost every newspaper in the eastern states. Formerly its sap was the basis of chewing gum, before chicle was employed.
