n elm (_Ulmus americana_)

One of the noblest of trees. Possesses a majestic, wide-spreading,
umbrella-shaped crown; is easily transplanted, and is suited to a
variety of soils.

2. Pin oak (_Quercus palustris_)

Has a symmetrical crown with low-drooping branches; requires a moist
situation.

3. European linden (_Tilia microphylla_)

Possesses a beautiful shade-bearing crown; grows well in ordinary
soil.

4. Red maple (_Acer rubrum_)

Shows pleasing colors at all seasons; grows best in a fairly rich,
moist soil.

5. Copper beech (_Fagus sylvatica_, _alropurpurea_)

Exceedingly beautiful in form, bark, and foliage and possesses great
longevity and sturdiness. It is difficult to transplant and
therefore only small trees from 6 to 10 feet in height should be
used.

6. Coffee tree (_Gymnocladus dioicus_)

A unique and interesting effect is produced by its coarse branches
and leaves. It is free from insects and disease; requires plenty of
light; will grow in poor soils.

7. European white birch (_Belula alba_)

A graceful tree and very effective as a single specimen on the lawn,
or in a group among evergreens; should be planted in early spring,
and special care taken to protect its tender rootlets.

8. Gingko or Maiden-hair tree (_Gingko biloba_)

Where there is plenty of room for the spread of its odd branches,
the gingko makes a picturesque specimen tree. It is hardy and free
from insect pests and disease.

9. Horsechestnut (_Aesculus hippocastanum_)

Carries beautiful, showy flowers, and has a compact, symmetrical
low-branched crown; is frequently subject to insects and disease.
The red flowering horsechestnut (_A. rubicunda_) is equally
attractive.

10. Sugar maple (_Acer saccharum_)

Has a symmetrical crown and colors beautifully in the fall; requires
a rich soil and considerable moisture.

11. Soulange's magnolia (_Magnolia soulangeana_)

Extremely hard and flowers in early spring before the leaves appear.

12. Flowering dogwood (_Cornus florida_)

Popular for its beautiful white flowers in the early spring and the
rich coloring of its leaves in the fall; does not grow to large
size. The red-flowering variety of this tree, though sometimes not
quite as hardy, is extremely beautiful.
