The Book of Woodcraft Black, Cherry, Sweet or Mahogany Birch. {Betula lento) The largest of the birches; a great tree, in Northern forests, up to 80 feet high. The bark is little birchy, rather like that of cherry, very dark, and aromatic. Wood dark, hard, clear-grained, very strong; used much for imitating mahogany. A cubic foot weighs 47 lbs. Noted for its sweet, aromatic twigs which made into tea are a fine tonic. "A decoction of the bark with copperas, is used for coloring woolen a beautiful and permanent drab, bordering on wine color." (Emerson.) Leaves 2| to 6 inches long. An oil in the bark is very good for sprains and rheumatism.
