twigs, narrow sharp-pointed buds, and by its small finely toothed
leaves. The large-toothed aspen has thicker and rather downy buds
and broader and more widely toothed leaves. The balsam poplar has a
large bud thickly covered with a sticky, pungent, gelatinous
substance.


GINGKO OR MAIDENHAIR TREE (_Gingko biloba_)

[Illustration: FIG. 44.--Gingko Trees.]

Distinguishing characters: The *peculiar branches* of this tree *emerge
upward* from a straight tapering trunk *at an angle of about 45°*
and give to the whole tree a striking, Oriental appearance, which is
quite different from that of any other tree, Fig. 44.

Leaf: Like that of a leaflet of maidenhair fern, Fig. 45.

Range: A native of northern China and introduced into eastern North
America.

Soil and location: The gingko will grow in poor soils.

Enemies: Practically free from insects and disease.

[Illustration: FIG. 45.--Leaves of the Gingko Tree.]

Value for planting: It makes a valuable tree for the street where heavy
shade is not the object and forms an excellent wide-spreading
specimen tree on the lawn.
