amp; papyri anointed or
rubbed with cedrium were on this account called _ced ati libri_. Drawers
of cedar or chips of the wood are now employed to protect furs and
woollen stuffs from injury by moths. Cedar-wood, however, is said to be
injurious to natural history objects, and to instruments placed in
cabinets made of it, as the resinous matter of the wood becomes
deposited upon them. _Cedria_, or cedar resin, is a substance similar to
mastic, that flows from incisions in the tree; and cedar manna is a
sweet exudation from its branches.

The genus _Cedrus_ contains two other species closely allied to _C.
Libani_--_Cedrus Deodara_, the deodar, or "god tree" of the Himalayas,
and _Cedrus atlantica_, of the Atlas range, North Africa. The deodar
forms forests on the mountains of Afghanistan, North Beluchistan and the
north-west Himalayas, flourishing in all the higher mountains from Nepal
up to Kashmir, at an elevation of from 5500 to 12,000 ft.; on the peaks
to the northern side of the Boorung Pass it grows to a height of 60 to
70 ft. before branching. The wood is close-grained, long-fibred,
perfumed and highly resinous, and resists the action of water. The
foliage is of a paler green, the leaves are slender and longer, and the
twigs are thinner than those of _C. Libani_. The tree is employed for a
variety of useful purposes, especially in building. It is now much
cultivated in England as an ornamental plant. _C. atlantica_, the Atlas
cedar, has shorter and denser leaves than _C. Libani_; the leaves are
glaucous, sometimes of a silvery whiteness, and the cones smaller than
in the other two forms; its wood also is hard, and more rapid in growth
than is that of the ordinary cedar. It is found at an altitude above the
sea of from 4000 to 6000 ft.

The name cedar is applied to a variety of trees, including species of
several genera of Conifers, _Juniperus_, _Thuja_, _Libocedrus_ and
_Cupressus_. _Thuja gigantea_ of western North America is known in the
United States as White (or Yellow) cedar, and the same name is applied
to _Cupressus Lawsoniana_, the Port Orford or Oregon cedar, a native of
the north-west States, and one of the most valuable juniper trees of
North America. The Bermuda cedar (_Juniperus bermudiana_) and the red or
American cedar (_J. virginiana_) are both much used in joinery and in
the manufacture of pencils; though other woods are now superseding them
for pencil-making. The Japanese cedar (_Cryptomeria jap
