378 The Book of Woodcraft White, Canoe or Paper Birch. (Betula papyri/era) A tall forest tree up to 80 feet high; the source of bark for canoes, etc. One of the most important trees in the northern forest. Besides canoes, wigwams, vessels and paper from its bark, it furnishes syrup from its sap and the inner bark is used as an emergency food. Every novice rediscovers for himself that the outer bark is highly inflammable as well as waterproof, and ideal for fire-lighting. Though so much like the Gray birch, it is larger, whiter, and without the ugly black scars at each limb. The timber is much the same, but this weighs 37 lbs. Its leaf and catkin distinguish it ; the former are 2 to 3 inches long.
