It is this grand tree that forms the famous forests of western Oregon, Washington, and the adjacent coast regions of British Columbia, where it attains its greatest size and is most abundant, making almost pure forests over thousands of square miles, dark and close and almost inaccessible, many of the trees towering with straight, imperceptibly tapered shafts to a height of three hundred feet, their heads together shutting out the light,—one of the largest, most widely distributed, and most important of all the Western giant.
The incense cedar (Libocedrus decurrens), when full grown, is a magnificent tree, one hundred and twenty to nearly two hundred feet high, five to eight and occasionally twelve feet in diameter, with cinnamon-colored bark and warm yellow-green foliage, and in general appearance like an arbor vitæ. It is distributed through the main forest from an elevation of three to six thousand feet, and in sheltered portions of cañons on the warm sides to seven thousand five hundred. In midwinter, when most trees are asleep, it puts forth its flowers. The pistillate are pale green and inconspicuous; but the staminate are yellow, about one fourth of an inch long, and are produced in myriads, tingeing all the branches with gold, and making the tree as it stands in the snow look like a gigantic goldenrod. Though scattered rather sparsely amongst its companions in the open woods, it is seldom out of sight, and its bright brown shafts and warm masses of plumy foliage make a striking feature of the landscape. While young and growing fast in an open situation no other tree of its size in the park forms so exactly tapered a pyramid. The branches, outspread in flat plumes and beautifully fronded, sweep gracefully downward and outward, except those near the top, which aspire; the lowest droop to the ground, overlapping one another, shedding off rain and snow, and making fine tents for storm-bound mountaineers and birds. In old age it becomes irregular and picturesque, mostly from accidents: running fires, heavy wet snow breaking the branches, lightning shattering the top, compelling it to try to make new summits out of side branches, etc. Still it frequently lives more than a thousand years, invincibly beautiful, and worthy its place beside the Douglas spruce and the great pines.
This unrivaled forest is still further enriched by two majestic silver firs, Abies magnifica and Abies concolor, bands of which come down from the main fir belt by cool shady ridges and glens. Abies magnifica is the noblest of its race, growing on moraines, at an elevation of seven thousand to eight thousand five hundred feet above the sea, to a height of two hundred or two hundred and fifty feet, and five to seven in diameter; and with these noble dimensions there is a richness and symmetry and perfection of finish not to be found in any other tree in the Sierra. The branches are whorled, in fives mostly, and stand out from the straight red purple bole in level or, on old trees, in drooping collars, every branch regularly pinnated like fern fronds, and clad with silvery needles, making broad plumes singularly rich and sumptuous.
