While the eastern states have not yet wakened up to the fact that this
tree is of value in ornamental planting, its decorative qualities in
open stands have been recognized for some time in eastern Europe, where
trees of considerable size, promising to attain almost primeval
proportions, are already flourishing.
RED FIR (_Abies magnifica_) is the largest fir in America. At its best
it attains a height of 250 feet and a diameter of ten, but that size is
rare. It has several names, magnificent fir, which is a translation of
its botanical name; redbark fir, California red fir, and golden fir. The
reference to red which occurs in its several names, is descriptive of
its heartwood. Its range lies on the Cascade mountains of southern
Oregon, and along the entire length of the western slope of the Sierra
Nevadas in California. It is common in southern Oregon and sometimes
forms nearly pure forests at elevations of 5,000 or 7,000 feet. It is
plentiful in the Sierra Nevada ranges at altitudes of from 6,000 to
9,000 feet. In southern California it ascends 10,000 feet. On old trees
the limbs, regularly whorled in collars of five, are usually pendulous
or down-growing and are regularly and precisely subdivided into branches
and twigs, the short, stiff blue-green leaves, which persist for ten
years, closely covering the upper side of the latter. Its cones are the
largest of the firs, are dark purple in color and grow erect on the
branches.
The cones are six or eight inches long, and three or four in diameter.
They present a fine appearance as they stand erect on the branches. The
seeds are large, but their strong wings are able to carry them away from
the immediate presence of the parent tree. The wings are extremely
beautiful, and flash light with the colors of the rainbow. Old trees are
protected by hard, dark-colored bark five or six inches thick. A forest
fire may pass through a stand of old firs without burning through the
bark, but young trees are not so protected, and are liable to be killed.
A study of the wood of the red fir reveals rather more favorable
qualities than the other firs afford. Sap and heartwood are more easily
distinguished than in the other species, the sapwood being much lighter
in color than the reddish heart. Contrary to the general rule among the
firs, this wood possesses considerable durability, especially when used
for purposes which bring it in contact with the soil. It is, however,
light, soft and weak, but has a close, fine grain and compact structure.
Seasoning defects, such as checking and warping, are liable to occur
unless properly guarded against. It weighs 29.30 pounds per cubic foot,
or nearly three pounds less than Douglas fir. It is used for rough
lumber, packing boxes, bridge floors, interior house finish, and fuel.
