Although so unconventional when full-grown, the sugar pine is a remarkably proper tree in youth--a strict follower of coniferous fashions--slim, erect, with leafy branches kept exactly in place, each tapering in outline and terminating in a spiry point. The successive forms between the cautious neatness of youth and the bold freedom of maturity offer a delightful study. At the age of fifty or sixty years, the shy, fashionable form begins to be broken up. Specialized branches push out and bend with the great cones, giving individual character, that becomes more marked from year to year. Its most constant companion is the yellow pine. The Douglas spruce, libocedrus, sequoia, and the silver fir are also more or less associated with it; but on many deep-soiled mountain-sides, at an elevation of about 5000 feet above the sea, it forms the bulk of the forest, filling every swell and hollow and down-plunging ravine. The majestic crowns, approaching each other in bold curves, make a glorious canopy through which the tempered sunbeams pour, silvering the needles, and gilding the massive boles and the flowery, park-like ground into a scene of enchantment. On the most sunny slopes the white-flowered, fragrant chamaebatia is spread like a carpet, brightened during early summer with the crimson sarcodes, the wild rose, and innumerable violets and gilias. Not even in the shadiest nooks will you find any rank, untidy weeds or unwholesome darkness. In the north sides of ridges the boles are more slender, and the ground is mostly occupied by an underbrush of hazel, ceanothus, and flowering dogwood, but not so densely as to prevent the traveler from sauntering where he will; while the crowning branches are never impenetrable to the rays of the sun, and never so interblended as to lose their individuality.
The Yellow Or Silver Pine
The Silver Pine (Pinus ponderosa), or Yellow Pine, as it is commonly called, ranks second among the pines of the Sierra as a lumber tree, and almost rivals the sugar pine in stature and nobleness of port. Because of its superior powers of enduring variations of climate and soil, it has a more extensive range than any other conifer growing on the Sierra. On the western slope it is first met at an elevation of about 2000 feet, and extends nearly to the upper limit of the timber-line. Thence, crossing the range by the lowest passes, it descends to the eastern base, and pushes out for a considerable distance into the hot, volcanic plains, growing bravely upon well-watered moraines, gravelly lake basins, climbing old volcanoes and dropping ripe cones among ashes and cinders.
The average size of full-grown trees on the western slope where it is associated with the sugar pine, is a little less than 200 feet in height and from five to six feet in diameter, though specimens considerably larger may easily be found. Where there is plenty of free sunshine and other conditions are favorable, it presents a striking contrast in form to the sugar pine, being a symmetrical spire, formed of a straight round trunk, clad with innumerable branches that are divided over and over again. Unlike the Yosemite form about one-half of the trunk is commonly branchless, but where it grows at all close three-fourths or more is naked, presenting then a more slender and elegant shaft than any other tree in the woods. The bark is mostly arranged in massive plates, some of them measuring four or five feet in length by eighteen inches in width, with a thickness of three or four inches, forming a quite marked and distinguishing feature. The needles are of a fine, warm, yellow-green color, six to eight inches long, firm and elastic, and crowded in handsome, radiant tassels on the upturning ends of the branches. The cones are about three or four inches long, and two and a half wide, growing in close, sessile clusters among the leaves.
The species attains its noblest form in filled-up lake basins, especially in those of the older yosemites, and as we have seen, so prominent a part does it form of their groves that it may well be called the Yosemite Pine.
The Jeffrey variety attains its finest development in the northern portion of the Range, in the wide basins of the McCloud and Pitt Rivers, where it forms magnificent forests scarcely invaded by any other tree. It differs from the ordinary form in size, being only about half as tall, in its redder and more closely-furrowed bark grayish-green foliage, less divided branches, and much larger cones; but intermediate forms come in which make a clear separation impossible, although some botanists regard it as a distinct species. It is this variety of ponderosa that climbs storm-swept ridges alone, and wanders out among the volcanoes of the Great Basin. Whether exposed to extremes of heat or cold, it is dwarfed like many other trees, and becomes all knots and angles, wholly unlike the majestic forms we have been sketching. Old specimens, bearing cones about as big as pineapples, may sometimes be found clinging to rifted rocks at an elevation of 7000 or 8000 feet, whose highest branches scarce reach above one's shoulders.
I have often feasted on the beauty of these noble trees when they were towering in all their winter grandeur, laden with snow--one mass of bloom; in summer, too, when the brown, staminate clusters hang thick among the shimmering needles, and the big purple burrs are ripening in the mellow light; but it is during cloudless wind-storms that these colossal pines are most impressively beautiful. Then they bow like willows, their leaves streaming forward all in one direction, and, when the sun shines upon them at the required angle, entire groves glow as if every leaf were burnished silver. The fall of tropic light on the crown of a palm is a truly glorious spectacle, the fervid sun-flood breaking upon the glossy leaves in long lance-rays, like mountain water among boulders at the foot of an enthusiastic cataract. But to me there is something more impressive in the fall of light upon these noble, silver pine pillars: it is beaten to the finest dust and shed off in myriads of minute sparkles that seem to radiate from the very heart of the tree as if like rain, falling upon fertile soil, it had been absorbed to reappear in flowers of light. This species also gives forth the finest wind music. After listening to it in all kinds
