THE WHITE BIRCH.
B. populifolia, Marsh.
The white birch is a small, short-lived tree that grows in swampy ground, its bark chalky white or grayish, with triangular rough patches of black, where branches are or have been. (The canoe birch has a clean bole, chalky white, with none of these ugly black patches.) A vagabond tree it is, with thin pointed leaves and long pencil-like catkins and seed cones. The chief contributions
of the poplar-leaved birch to the well-being of men are that it clothes with beauty the most uniniviting situations, and that it comes again, after fire or other general slaughter, promptly and abundantly, from stump and scattered seed.
