birch, also known as black birch or cherry birch, occurs only
in the highlands and mountains of our state. This tree develops
best in mountain coves and on rich slopes, where it reaches an
average height of 50 to 60 feet and a diameter of 2 to 3 feet.
Sweet birch leaves are oval to oblong, 2 1/2 to 5 inches long
and are sharply toothed. Stems of the leaves are hairy, and tufts
of hair occur in the axils of the veins on the undersides of the

prominent horizontal lenticels. (A lenticel is a small opening
in the bark of a twig; the opening usually is surrounded by rough,
corky tissue.) The bark becomes almost black with maturity. On

but is considered one of the best for firewood because of its
