diverging wings. 
The Striped Maple is a small tree, seldom exceed- 
ing the height of thirty feet, and frequently not more 
than half that stature. It is found in northern woods 
from Maine to Wisconsin, and southward along the 
summits of the Alleghanies. It has heavy, dense 
foliage, and smooth light-green bark, striped longi- 
tudinally with dark lines. The wood is more durable 
than that of other species of Maple, but is too small 
for use. It is worthy of notice only as a highly orna- 
mental tree. If grafted on larger species of Maple, 
it is said to reach three or four times its ordinary 
size. Itis propagated from seed in the same manner 
as the Sugar Maple. 
% Acer spicatum—the Mountain Maple, 
Is a still smaller tree, very ornamental; and may, 
also, be increased in size by grafting on larger species. 
8. Acer platanoides—Norway Maple. 
Leaves, milky, broadly cordate, five-lobed, coarsely 
toothed ; fruit, diverging; flowers, pendulous. 
This species isa native of the north of Europe, 
and grows to the height of sixty feet or more. It 
considerably resembles the Sugar Maple, and, like 
that, produces sap from which sugar is made. It is 
of slow growth for the first three or four years from 
the seed, but afterwards increases in size rapidly. As 
an ornamental tree it has some advantages over the 
Sugar Maple; its foliage is more dense, its leaves
