Wood
Red Cedar is very fine-grained, soft, light, durable, fragrant, and
of a pinkish-red color. Much wood is derived from the Red Cedars,
_Juniperus virginiana_, _Juniperus scopulorum_, and _Juniperus
barbadensis_, of the Eastern, Western, and Southern States
respectively. Although seen in construction, red cedar is chiefly
used in chests, closets, lead-pencils, and cigar-boxes. One hundred
and twenty-five thousand trees (125,000)[93] are annually required
for lead-pencils alone. The waste is often converted into shavings
and used instead of camphor to protect woolens. The demand is greater
than the supply. Trees are easily grown on almost any soil. Trees
and wood are subject to fungus diseases which apparently cease after
trees have been felled; the wood is then durable.[94]
White Cedar is best defined as all cedar that is not "red cedar,"
[p168] and is obtained from several valuable trees.[95] The
arborvitæs (_T. occidentalis_) vary in size from large bushes used
in hedging and ornamentation to small-sized trees gathered for wood.
They are most vigorous on cold, wet areas known as cedar swamps.[96]
The giant arborvitæ (_T. gigantea_), noted for its great girth, and
the yellow and Lawson Cypresses, are important Pacific coast species.
The incense cedar, while much subject to fungus trouble, is also
prized.[97] White cedar wood is durable, plentiful, and employed in
exposed positions as ties and shingles.
Arborvitæs (_Thuya_) have very small overlapping leaves that form
flat rods or fan-like sprays. The cones are oblong, less than
one-half inch in length, and all of their six or eight scales
separate or open when ripe. The cypresses (_Chamæcyparis_) exhibit
similar foliage, but their tiny cones are simple, roughened, close,
or solid globules. The Junipers (_Juniperus_) often, but not always,
bear bluish-black berries powdered with a whitish-blue bloom. The
true cedars (_Cedrus_) differ from the others in that they have
simple needle leaves, an inch, more or less, in length, together with
cones erect and several inches in length. The Deodar or cedar of
India is of this genus. The principal American red and white cedars
are as follows:
Red Cedar.
Red Cedar (_Juniperus virginiana_).
Red Cedar (_Juniperus scopulorum_).
Red Cedar (_Juniperus barbadensis_).
Spanish Cedar. (See page 99.)
White Cedar.
Arborvitæ (_Thuya occidentalis_).
Canoe Cedar (_Thuya gigantea_).
White Cedar (_Chamæcyparis thyoides_).
Port Orford Cedar (_Chamæcyparis lawsoniana_).
Yellow Cedar (_Chamæcyparis nutkaensis_).
Incense Cedar (_Libodecrus decurrens_).
