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.
