The Douglas Spruce

The Douglas Spruce (Pseudotsuga Douglasii) is one of the largest and longest-lived of the giants that flourish throughout the main pine belt, often attaining a height of nearly 200 feet, and a diameter of six or seven feet. Where the growth is not too close, the stout, spreading branches, covering more than half of the trunk, are hung with innumerable slender, drooping sprays, handsomely feathered with the short leaves which radiate at right angles all around them. This vigorous tree is ever beautiful, welcoming the mountain winds and the snow as well as the mellow summer light; and it maintains its youthful freshness undiminished from century to century through a thousand storms. It makes its finest appearance during the months of June and July, when the brown buds at the ends of the sprays swell and open, revealing the young leaves, which at first are bright yellow, making the tree appear as if covered with gay blossoms; while the pendulous bracted cones, three or four inches long, with their shell-like scales, are a constant adornment.

The young trees usually are assembled in family groups, each sapling exquisitely symmetrical. The primary branches are whorled regularly around the axis, generally in fives, while each is draped with long, feathery sprays that descend in lines as free and as finely drawn as those of falling water.

In Oregon and Washington it forms immense forests, growing tall and mast-like to a height of 300 feet, and is greatly prized as a lumber tree. Here it is scattered among other trees, or forms small groves, seldom ascending higher than 5500 feet, and never making what would be called a forest. It is not particular in its choice of soil: wet or dry, smooth or rocky, it makes out to live well on them all. Two of the largest specimens, as we have seen, are in Yosemite; one of these, more than eight feet in diameter, is growing on a moraine; the other, nearly as large, on angular blocks of granite. No other tree in the Sierra seems so much at home on earthquake taluses and many of these huge boulder-slopes are almost exclusively occupied by it.

The Incense Cedar

Incense Cedar (Libocedrus decurrens), already noticed among the Yosemite trees, is quite generally distributed throughout the pine belt without exclusively occupying any considerable area, or even making extensive groves. On the warmer mountain slopes it ascends to about 5000 feet, and reaches the climate most congenial to it at a height of about 4000 feet, growing vigorously at this elevation in all kinds of soil and, in particular, it is capable of enduring more moisture about its roots than any of its companions excepting only the sequoia.

Casting your eye over the general forest from some ridge-top you can identify it by the color alone of its spiry summits, a warm yellow-green. In its youth up to the age of seventy or eighty years, none of its companions forms so strictly tapered a cone from top to bottom. As it becomes older it oftentimes grows strikingly irregular and picturesque. Large branches push out at right angles to the trunk, forming stubborn elbows and shoot up parallel with the axis. Very old trees are usually dead at the top. The flat fragrant plumes are exceedingly beautiful: no waving fern-frond is finer in form and texture. In its prime the whole tree is thatched with them, but if you would see the libocedrus in all its glory you must go to the woods in midwinter when it is laden with myriads of yellow flowers about the size of wheat grains, forming a noble illustration of Nature’s immortal virility and vigor. The mature cones, about three-fourths of an inch long, born on the ends of the plumy branchlets, serve to enrich still more the surpassing beauty of this winter-blooming tree-goldenrod.
