Going to the woods is going home; for I suppose we came from the woods originally. But in some of nature’s forests the adventurous traveler seems a feeble, unwelcome creature; wild beasts and the weather trying to kill him, the rank, tangled vegetation, armed with spears and stinging needles, barring his way and making life a hard struggle. Here everything is hospitable and kind, as if planned for your pleasure, ministering to every want of body and soul. Even the storms are friendly and seem to regard you as a brother, their beauty and tremendous fateful earnestness charming alike. But the weather is mostly sunshine, both winter and summer and the clear sunny brightness of the park is one of its most striking characteristics. Even the heaviest portions of the main forest belt, where the trees are tallest and stand closest, are not in the least gloomy. The sunshine falls in glory through the colossal spires and crowns, each a symbol of health and strength, the noble shafts faithfully upright like the pillars of temples, upholding a roof of infinite leafy interlacing arches and fretted skylights. The more open portions are like spacious parks, carpeted with small shrubs, or only with the fallen needles sprinkled here and there with flowers. In some places, where the ground is level or slopes gently, the trees are assembled in groves, and the flowers and underbrush in trim beds and thickets as in landscape gardens or the lovingly planted grounds of homes; or they are drawn up in orderly rows around meadows and lakes and along the brows of cañons. But in general the forests are distributed in wide belts in accordance with climate and the comparative strength of each kind in gaining and holding possession of the ground, while anything like monotonous uniformity is prevented by the grandly varied topography, and by the arrangement of the best soilbeds in intricate patterns like embroidery; for these soilbeds are the moraines of ancient glaciers more or less modified by weathering and stream action, and the trees trace them over the hills and ridges, and far up the sides of the mountains, rising with even growth on levels, and towering above one another on the long rich slopes prepared for them by the vanished glaciers.
Timber line at Thousand Islet Lake,
near Mt. Ritter, Yosemite
On the way to Yosemite Valley, you get some grand views over the forests of the Merced and Tuolumne basins and glimpses of some of the finest trees by the roadside without leaving your seat in the stage. But to learn how they live and behave in pure wildness, to see them in their varying aspects through the seasons and weather, rejoicing in the great storms, in the spiritual mountain light, putting forth their new leaves and flowers when all the streams are in flood and the birds are singing, and sending away their seeds in the thoughtful Indian summer when all the landscape is glowing in deep calm enthusiasm,—for this you must love them and live with them, as free from schemes and cares and time as the trees themselves.
And surely nobody will find anything hard in this. Even the blind must enjoy these woods, drinking their fragrance, listening to the music of the winds in their groves, and fingering their flowers and plumes and cones and richly furrowed boles. The kind of study required is as easy and natural as breathing. Without any great knowledge of botany or wood-craft, in a single season you may learn the name and something more of nearly every kind of tree in the park.
With few exceptions all the Sierra trees are growing in the park,—nine species of pine, two of silver fir, one each of Douglas spruce, libocedrus, hemlock, juniper, and sequoia,—sixteen conifers in all, and about the same number of round-headed trees, oaks, maples, poplars, laurel, alder, dogwood, tumion, etc.
The first of the conifers you meet in going up the range from the west is the digger nut-pine (Pinus Sabiniana), a remarkably open, airy, wide-branched tree, forty to sixty feet high, with long, sparse, grayish green foliage and large cones. At a height of fifteen to thirty feet from the ground the trunk usually divides into several main branches, which, after bearing away from one another, shoot straight up and form separate heads as if the axis of the tree had been broken, while the secondary branches divide again and again into rather slender sprays loosely tasseled, with leaves eight to twelve inches long. The yellow and purple flowers are about an inch long, the staminate in showy clusters. The big, rough, burly cones, five to eight or ten inches in length and five or six in diameter, are rich brown in color when ripe, and full of hard-shelled nuts that are greatly prized by Indians and squirrels. This strange-looking pine, enjoying hot sunshine like a palm, is sparsely distributed along the driest part of the Sierra among small oaks and chaparral, and with its gray mist of foliage, strong trunk and branches, and big cones seen in relief on the glowing sky, forms the most striking feature of the foothill vegetation.
Pinus attenuata is a small, slender, arrowy tree, with pale green leaves in threes, clustered flowers half an inch long, brownish yellow and crimson, and cones whorled in conspicuous clusters around the branches and also around the trunk. The cones never fall off or open until the tree dies. They are about four inches long, exceedingly strong and solid, and varnished with hard resin forming a waterproof and almost worm and squirrel proof package, in which the seeds are kept fresh and safe during the lifetime of the tree. Sometimes one of the trunk cones is overgrown and imbedded in the heart wood like a knot, but nearly all are pushed out and kept on the surface by the pressure of the successive layers of wood against the base.
This admirable little tree grows on brushy, sun-beaten slopes, which from their position and the inflammable character of the vegetation are most frequently fire-swept. These grounds it is able to hold against all comers, however big and strong, by saving its seeds until death, when all it has produced are scattered over the bare cleared ground, and a new generation quickly springs out of the ashes. Thus the curious fact that all the trees of extensive groves and belts are of the same age is accounted for, and their slender habit; for the lavish abundance of seed sown at the same time makes a crowded growth, and the seedlings with an even start rush up in a hurried race for light and life.
Only a few of the attenuata and Sabiniana pines are within the boundaries of the park, the former on the side of the Merced Cañon, the latter on the walls of Hetch-Hetchy Valley and in the cañon below it.
The nut-pine ( Pinus monophylla ) is a small, hardy, contended-looking tree, about fifteen or twenty feet high and a foot in diameter. In its youth the close radiating and aspiring branches form a handsome broad-based pyramid, but when fully grown it becomes round-topped, knotty, and irregular, throwing out crooked divergent limbs like an apple tree. The leaves are pale grayish green, about an inch and a half long, and instead of being divided into clusters they are single, round, sharp-pointed, and rigid like spikes, amid which in the spring the red flowers glow brightly. The cones are only about two inches in length and breadth, but nearly half of their bulk is made up of sweet nuts.
This fruitful little pine grows on the dry east side of the park, along the margin of the Mono sage plain, and is the commonest tree of the short mountain ranges of the Great Basins. Tens of thousands of acres are covered with it, forming bountiful orchards for the Red-man. Being so low and accessible, the cones are easily beaten off with poles, and the nuts procured by roasting until the scales open. To the tribes of the desert and sage plains these seeds are the staff of life. They are eaten either raw or parched, or in the form of mush or cakes after being pounded into meal. The time of nut harvest in the autumn is the Indian’s merriest time of all the year. An industrious squirrelish family can gather fifty or sixty bushels in a single month before the snow comes, and then their bread for the winter is sure.
The white pine (Pinus flexilis) is widely distributed through the Rocky Mountains and the ranges of the Great Basin, where in many places it grows to a good size, and is an important timber tree where none better is to be found. In the park it is sparsely scattered along the eastern flank of the range from Mono Pass southward, above the nut-pine, at an elevation of from eight to ten thousand feet, dwarfing to a tangled bush near the timber-line, but under favorable conditions attaining a height of forty or fifty feet, with a diameter of three to five. The long branches show a tendency to sweep out in bold curves, like those of the mountain and sugar pines to which it is closely related. The needles are in clusters of five, closely packed on the ends of the branchlets. The cones are about five inches long,—the smaller ones nearly oval, the larger cylindrical. But the most interesting feature of the tree is its bloom, the vivid red pistillate flowers glowing among the leaves like coals of fire.
The dwarfed pine or white-barked pine (Pinus albicaulis) is sure to interest every observer on account of its curious low matted habit, and the great height on the snowy mountains at which it bravely grows. It forms the extreme edge of the timber-line on both flanks of the summit mountains-if so lowly a tree can be called timber-at an elevation of ten to twelve thousand feet above the level of the sea. Where it is first met on the lower limit of its range it may be thirty or forty feet high, but farther up the rocky wind-swept slopes, where the snow lies deep and heavy for six months of the year, it makes shaggy clumps and beds, crinkled and pressed flat, over which you can easily walk. Nevertheless in this crushed, down-pressed, felted condition it clings hardily to life, puts forth fresh leaves every spring on the ends of its tasseled branchlets, blooms bravely in the lashing blasts with abundance of gay red and purple flowers, matures its seeds in the short summers, and often outlives the favored giants of the sun lands far below. One of the trees that I examined was only about three feet high, with a stem six inches in diameter at the ground, and branches that spread out horizontally as if they had grown up against a ceiling; yet it was four hundred and twenty-six years old, and one of its supple branchlets, about an eighth of an inch in diameter inside the bark, was seventy-five years old, and so tough that I tied it into knots. At the age of this dwarf many of the sugar and yellow pines and sequoias are seven feet in diameter and over two hundred feet high.
In detached clumps never touched by fire the fallen needles of centuries of growth make fine elastic mattresses for the weary mountaineer, while the tasseled branchlets spread a roof over him, and the dead roots, half resin, usually found in abundance, make capital camp-fires, unquenchable in thickest storms of rain or snow. Seen from a distance the belts and patches darkening the mountain sides look like mosses on a roof, and bring to mind Dr. Johnson’s remarks on the trees of Scotland. His guide, anxious for the honor of Mull, was still talking of its woods and pointing them out. “Sir,” said Johnson, “I saw at Tobermory what they called a wood, which I unluckily took for heath. If you show me what I shall take for furze, it will be something.”
The mountain pine ( Pinus monticola ) is far the largest of the Sierra tree mountaineers. Climbing nearly as high as the dwarf albicaulis, it is still a giant in size, bold and strong, standing erect on the storm-beaten peaks and ridges, tossing its cone-laden branches in the rough winds, living a thousand years, and reaching its greatest size-ninety to a hundred feet in height, six to eight in diameter-just where other trees, its companions, are dwarfed. But it is not able to endure burial in snow so long as the albicaulis and flexilis. Therefore, on the upper limit of its range it is found on slopes which, from their steepness or exposure, are least snowy. Its soft graceful beauty in youth, and its leaves, cones, and outsweeping feathery branches constantly remind you of the sugar pine, to which it is closely allied. An admirable tree, growing nobler in form and size the colder and balder the mountains about it.
The giants of the main forest in the favored middle region are the sequoia, sugar pine, yellow pine, libocedrus, Douglas spruce, and the two silver firs. The park sequoias are restricted to two small groves, a few miles apart, on the Tuolumne and Merced divide, about seventeen miles from Yosemite Valley. The Big Oak Flat road to the valley runs through the Tuolumne Grove, the Coulterville through the Merced. The more famous and better known Mariposa Grove, belonging to the state, lies near the southwest corner of the park, a few miles above Wawona.
The sugar pine (Pinus Lambertiana) is first met in the park in open, sunny, flowery woods, at an elevation of about thirty-five hundred feet above the sea, attains full development at a height between five and six thousand feet, and vanishes at the level of eight thousand feet. In many places, especially on the northern slopes of the main ridges between the rivers, it forms the bulk of the forest, but mostly it is intimately associated with its noble companions, above which it covers in glorious majesty on every hill, ridge, and plateau from one extremity of the range to the other, a distance of five hundred miles,—the largest, noblest, and most beautiful of all the seventy or eighty species of pine trees in the world, and of all the conifers second only to King Sequoia.
A good many are from two hundred to two hundred and twenty feet in height, with a diameter at four feet from the ground of six to eight feet, and occasionally a grand patriarch, seven or eight hundred years old, is found that is ten or even twelve feet in diameter and two hundred and forty feet high, with a magnificent crown seventy feet wide. David Douglas, who discovered “this most beautiful and immensely grand tree” in the fall of 1826 in southern Oregon, says that the largest of several that had been blown down, “at three feet from the ground was fifty-seven feet nine inches in circumference” (or fully eighteen feet in diameter); “at one hundred and thirty-four feet, seventeen feet five inches; extreme length, two hundred and forty-five feet.” Probably for fifty-seven we should read thirty-seven for the base measurement, which would make it correspond with the other dimensions; for none of this species with anything like so great a girth has since been seen. A girth of even thirty feet is uncommon. A fallen specimen that I measured was nine feet three inches in diameter inside the bark at four feet from the ground, and six feet in diameter at a hundred feet from the ground. A comparatively young tree, three hundred and thirty years old, that had been cut down, measured seven feet across the stump. was three feet three inches in diameter at a height of one hundred and fifty feet, and two hundred and ten feet in length.
The trunk is a round, delicately tapered shaft with finely furrowed purplish-brown bark, usually free of limbs for a hundred feet or more. The top is furnished with long and comparatively slender branches, which sweep gracefully downward and outward, feathered with short tasseled branchlets, and divided only at the ends, forming a palmlike crown fifty to seventy-five feet wide, but without the monotonous uniformity of palm crowns or of the spires of most conifers. The old trees are as tellingly varied and picturesque as oaks. No two are alike, and we are tempted to stop and admire every one we come to, whether as it stands silent in the calm balsam-scented sunshine or waving in accord with enthusiastic storms. The leaves are about three or four inches long, in clusters of five, finely tempered, bright lively green, and radiant. The flowers are but little larger than those of the dwarf pine, and far less showy. The immense cylindrical cones, fifteen to twenty or even twenty-four inches long and three in diameter, hang singly or in clusters, like ornamental tassels, at the ends of the long branches, green, flushed with purple on the sunward side. Like those of almost all the pines they ripen in the autumn of the second season from the flower, and the seeds of all that have escaped the Indians, bears, and squirrels take wing and fly to their places. Then the cones become still more effective as ornaments, for by the spreading of the scales the diameter is nearly doubled, and the color changes to a rich brown. They remain on the tree the following winter and summer; therefore few fertile trees are ever found without them. Nor even after they fall is the beauty work of these grand cones done, for they make a fine show on the flowery, needle-strewn ground. The wood is pale yellow, fine in texture, and deliciously fragrant. The sugar, which gives name to the tree, exudes from the heart wood on wounds made by fire or the axe, and forms irregular crisp white candy-like masses. To the taste of most people it is as good as maple sugar, though it cannot be eaten in large quantities.
No traveler, whether a tree lover or not, will ever forget his first walk in a sugar-pine forest. The majestic crowns approaching one another make a glorious canopy, through the feathery arches of which the sunbeams pour, silvering the needles and gilding the stately columns and the ground into a scene of enchantment.
The yellow pine (Pinus ponderosa) is surpassed in size and nobleness of port only by its kingly companion. Full-grown trees in the main forest where it is associated with the sugar pine, are about one hundred and seventy-five feet high, with a diameter of five to six feet, though much larger specimens may easily be found. The largest I ever measured was little over eight feet in diameter four feet above the ground, and two hundred and twenty feet high. Where there is plenty of sunshine and other conditions are favorable, it is a massive symmetrical spire, formed of a strong straight shaft clad with innumerable branches, which are divided again and again into stout branchlets laden with bright shining needles and green or purple cones. Where the growth is at all close half or more of the trunk is branchless. The species attains its greatest size and most majestic form in open groves on the deep, well-drained soil of lake basins at an elevation of about four thousand feet. There nearly all the old trees are over two hundred feet high, and the heavy, leafy, much-divided branches sumptuously clothe the trunk almost to the ground. Such trees are easily climbed, and in going up the winding stairs of knotty limbs to the top you will gain a most telling and memorable idea of the height, the richness and intricacy of the branches, and the marvelous abundance and beauty of the long shining elastic foliage. In tranquil weather, you will see the firm outstanding needles in calm content, shimmering and throwing off keen minute rays of light like lances of ice; but when heavy winds are blowing, the strong towers bend and wave in the blast with eager wide-awake enthusiasm, and every tree in the grove glows and flashes in one mass of white sunfire.
Both the yellow and sugar pines grow rapidly on good soil where they are not crowded. At the age of a hundred years they are about two feet in diameter and a hundred or more high. They are then very handsome, though very unlike: the sugar pine, lithe, feathery, closely clad with ascending branches; the yellow, open, showing its axis from the ground to the top, its whorled branches but little divided as yet, spreading and turning up at the ends with magnificent tassels of long stout bright needles, the terminal shoot with its leaves being often three or four feet long and a foot and a half wide, the most hopeful looking and the handsomest tree-top in the woods. But instead of increasing, like its companion, in wildness and individuality of form with age, it becomes more evenly and compactly spiry. The bark is usually very thick, four to six inches at the ground, and arranged in large plates, some of them on the lower part of the trunk four or five feet long and twelve to eighteen inches wide, forming a strong defense against fire. The leaves are in threes, and from three inches to a foot long. The flowers appear in May: the staminate pink or brown, in conspicuous clusters two or three inches wide; the pistillate crimson, a fourth of an inch wide, and mostly hidden among the leaves on the tips of the branchlets. The cones vary from about three to ten inches in length, two to five in width, and grow in sessile outstanding clusters near the ends of the upturned branchlets.
Being able to endure fire and hunger and many climates this grand tree is widely distributed: eastward from the coast across the broad Rocky Mountain ranges to the Black Hills of Dakota, a distance of more than a thousand miles, and southward from British Columbia, near latitude 51, to Mexico, about fifteen hundred miles. South of the Columbia River it meets the sugar pine, and accompanies it all the way down along the Coast and Cascade mountains and the Sierra and southern ranges to the mountains of the peninsula of Lower California, where they find their southmost homes together. Pinus ponderosa is extremely variable, and much bother it gives botanists who try to catch and confine the unmanageable proteus in two or a dozen species,—Jeffreyi, deflexa, Apacheca latifolia, etc. But in all its wanderings, in every form, it manifests noble strength. Clad in thick bark like a warrior in mail, it extends its bright ranks over all the high ranges of the wild side of the continent: flourishes in the drenching fog and rain of the northern coast at the level of the sea, in the snow-laden blasts of the mountains, and the white glaring sunshine of the interior plateaus and plains, on the borders of mirage-haunted deserts, volcanoes, and lava beds, waving its bright plumes in hot winds undaunted, blooming every year for centuries, and tossing big ripe cones among the cinders and ashes of nature’s hearths.
The Douglas spruce grows with the great pines, especially on the cool north sides of ridges and cañons, and is here nearly as large as the yellow pine, but less abundant. The wood is strong and tough, the bark thick and deeply furrowed, and on vigorous, quick-growing trees the stout, spreading branches are covered with innumerable slender, swaying sprays, handsomely clothed with short leaves. The flowers are about three fourths of an inch in length, red or greenish, not so showy as the pendulous bracted cones. But in June and July, when the young bright yellow leaves appear, the entire tree seems to be covered with bloom.
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 vit. 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.
The flowers are in their prime about the middle of June: the staminate red, growing on the underside of the branchlets in crowded profusion, giving a rich color to nearly all the tree; the pistillate greenish yellow tinged with pink, standing erect on the upper side of the topmost branches; while the tufts of young leaves, about as brightly colored as those of the Douglas spruce, push out their fragrant brown buds a few weeks later, making another grand show.
The cones mature in a single season from the flowers. When full grown they are about six to eight inches long, three or four in diameter, blunt, massive, cylindrical, greenish gray in color, covered with a fine silvery down, and beaded with transparent balsam, very rich and precious-looking, standing erect like casks on the topmost branches. If possible, the inside of the cone is still more beautiful. The scales and bracts are tinged with red, and the seed wings are purple with bright iridescence.
Abies concolor, the white silver fir, grows best about two thousand feet lower than the magnifica. It is nearly as large, but the branches are less regularly pinnated and whorled, the leaves are longer, and instead of standing out around the branchlets or turning up and clasping them they are mostly arranged in two horizontal or ascending rows, and the cones are less than half as large. The bark of the magnifica is reddish purple and closely furrowed, that of the concolor is gray and widely furrowed,—a noble pair, rivaled only by the Abies grandis, amabilis, and nobilis of the forests of Oregon, Washington, and the Northern California Coast Range. But none of these northern species form pure forests that in extent and beauty approach those of the Sierra.
The seeds of the conifers are curiously formed and colored, white, brown, purple, plain or spotted like birds eggs, and expecting the juniper they are all handsomely and ingeniously winged with reference to their distribution. They are a sort of cunningly devised flying machines,—one-winged birds, birds with but one feather,—and they take but one flight, all save those which, after flying from the cone-nest in calm weather, chance to alight on branches where they have to wait for a wind. And though these seed wings are intended for only a moment’s use, they are as thoughtfully colored and fashioned as the wings of birds, and require from one to two seasons to grow. Those of the pine, fir, hemlock, and spruce are curved in such manner that, in being dragged through the air by the seeds, they are made to revolve, whirling the seeds in a close spiral, and sustaining them long enough to allow the winds to carry them to considerable distances,—a style of flying full of quick merry motion, strikingly contrasted to the sober dignified sailing of seeds on tufts of feathery pappus. Surely no merrier adventurers ever set out to seek their fortunes. Only in the fir woods are large flocks seen; for, unlike the cones of the pine, spruce, hemlock, etc., which let the seeds escape slowly, one or two at a time, by spreading the scales, the fir cones when ripe fall to pieces, and let nearly all go at once in favorable weather. All along the Sierra for hundreds of miles, on dry breezy autumn days, the sunny spaces in the woods among the colossal spires are in a whirl with these shining purplewinged wanderers, notwithstanding the harvesting squirrels have been working at the top of their speed for weeks trying to cut off every cone before the seeds were ready to swarm and fly. Sequoia seeds have flat wings, and glint and glance in their flight like a boy’s kite. The dispersal of juniper seeds is effected by the plum and cherry plan of hiring birds at the cost of their board, and thus obtaining the use of a pair of extra good wings.
Above the great fir belt, and below the ragged beds and fringes of the dwarf pine, stretch the broad dark forests of Pinus contorta, var. Murrayana, usually called tamarack pine. On broad fields of moraine material it forms nearly pure forests at an elevation of about eight or nine thousand feet above the sea, where it is a small, well proportioned tree, fifty or sixty feet high and one or two in diameter, with thin gray bark, crooked much-divided straggling branches, short needles in clusters of two, bright yellow and crimson flowers, and small prickly cones. The very largest I ever measured was ninety feet in height, and a little over six feet in diameter four feet above the ground. On moist well-drained soil in sheltered hollows along streamsides it grows tall and slender with ascending branches, making graceful arrowy spires fifty to seventy-five feet high, with stems only five or six inches thick.
The most extensive forest of this pine in the park lies to the north of the Big Tuolumne Meadows,—a famous deer pasture and hunting ground of the Mono Indians. For miles over wide moraine beds there is an even, nearly pure growth, broken only by glacier meadows, around which the trees stand in trim array, their sharp spires showing on fine advantage both in green flowery summer and white winter. On account of the closeness of its growth in many places, and the thinness and gumminess of its bark, it is easily killed by running fires, which work wide-spread destruction in its ranks; but a new generation rises quickly from the ashes, for all or a part of its seeds are held in reserve for a year or two or many years, and when the tree is killed the cones open and the seeds are scattered over the burned ground like those of the attenuata.
Next to the mountain hemlock and the dwarf pine this species best endures burial in heavy snow, while in braving hunger and cold on rocky ridgetops it is not surpassed by any. It is distributed from Alaska to Southern California, and inland across the Rocky Mountains, taking many forms in accordance with demands of climate, soil, rivals, and enemies; growing patiently in bogs and on sand dunes beside the sea where it is pelted with salt scud, on high snowy mountains and down in the throats of extinct volcanoes; springing up with invincible vigor after every devastating fire and extending its conquests farther.
The sturdy storm-enduring red cedar ( Juniperus occidentalis) delights to dwell on the tops of granite domes and ridges and glacier pavements of the upper pine belt, at an elevation of seven to ten thousand feet, where it can get plenty of sunshine and snow and elbow-room without encountering quick-growing overshadowing rivals. They never make anything like a forest, seldom come together even in groves, but stand out separate and independent in the wind, clinging by slight joints to the rock, living chiefly on snow and thin air, and maintaining tough health on this diet for two thousand years or more, every feature and gesture expressing steadfast dogged endurance. The largest are usually about six or eight feet in diameter, and fifteen or twenty in height. A very few are ten feet in diameter, and on isolated moraine heaps forty to sixty feet in height. Many are mere stumps, as broad as high, broken by avalanches and lightning, picturesquely tufted with dense gray scalelike foliage, and giving no hint of dying. The staminate flowers are like those of the libocedrus, but smaller; the pistillate are inconspicuous. The wood is red, fine-grained, and fragrant; the bark bright cinnamon and red, and in thrifty trees is strikingly braided and reticulated, flaking off in thin lustrous ribbons, which the Indians used to weave into matting and coarse cloth. These brown unshakable pillars, standing solitary on polished pavements with bossy masses of foliage in their arms, are exceedingly picturesque, and never fail to catch the eye of the artist. They seem sole survivors of some ancient race, wholly unacquainted with their neighbors.
I have spent a good deal of time, trying to determine their age, but on account of dry not which honeycombs most of the old ones, I never got a complete count of the largest. Some are undoubtedly more than two thousand years old; for though on good moraine soil they grow about as fast as oaks, on bare pavements and smoothly glaciated overswept granite ridges in the dome region they grow extremely slowly. One on the Starr King ridge, only two feet eleven inches in diameter, was eleven hundred and forty years old. Another on the same ridge, only one foot seven and a half inches in diameter, had reached the age of eight hundred and thirty-four years. The first fifteen inches from the bark of a medium-sized tree-six feet in diameter-on the north Tenaya pavement had eight hundred and fifty-nine layers of wood, or fifty-seven to the inch. Beyond this the count was stopped by dry rot and scars of old wounds. The largest I examined was thirty-three feet in girth, or nearly ten in diameter; and though I failed to get anything like a complete count, I learned enough from this and many other specimens to convince me that most of the trees eight to ten feet thick standing on pavements are more than twenty centuries of age rather than less. Barring accidents, for all I can see, they would live forever. When killed, they waste out of existence about as slowly as granite. Even when overthrown by avalanches, after standing so long, they refuse to lie at rest, leaning stubbornly on their big elbows as if anxious to rise, and while a single root holds to the rock putting forth fresh leaves with a grim never-say-die and never-lie-down expression.
As the juniper is the most stubborn and unshakable of trees, the mountain hemlock (Tsuga Mertensiana) is the most graceful and pliant and sensitive, responding to the slightest touches of the wind. Until it reaches a height of fifty or sixty feet it is sumptuously clothed down to the ground with drooping branches, which are divided into countless delicate waving sprays, grouped and arranged in most indescribably beautiful ways, and profusely sprinkled with handsome brown cones. The flowers also are peculiarly beautiful and effective; the pistillate very dark rich purple; the estimate blue of so fine and pure a tone that the best azure of the high sky seems to be condensed in them.
Though apparently the most delicate and feminine of all the mountain trees, it grows best where the snow lies deepest, at an elevation of from nine thousand to nine thousand five hundred feet, in hollows on the northern slopes of mountains and ridges. But under all circumstances and conditions of weather and soil, sheltered from the main currents of the winds or in blank exposure to them, well fed or starved, it is always singularly graceful in habit. Even at its highest limit in the park, ten thousand five hundred feet above the sea on exposed ridgetops, where it crouches and huddles close together in low thickets like those of the dwarf pine, it still contrives to put forth its sprays and branches in forms of irrepressible beauty, while on moist well-drained moraines it displays a perfectly tropical luxuriance of foliage, flower, and fruit.
In the first winter storms the snow is oftentimes soft, and lodges in the dense leafy branches, pressing them down against the trunk, and the slender drooping axis bends lower and lower as the load increases, until the top touches the ground and an ornamental arch is made. Then, as storm succeeds storm and snow is heaped on snow, the whole tree is at last buried, not again to see the light or move leaf or limb until set free by the spring thaws in June or July. Not the young saplings only are thus carefully covered and put to sleep in the whitest of white beds for five or six months of the year, but trees thirty and forty feet high. From April to May, then the snow is compacted, you may ride over the prostrate groves without seeing a single branch or leaf of them. In the autumn they are full of merry life, when Clark crows, squirrels, and chipmunks are gathering the abundant crop of seeds while the deer rest beneath the thick concealing branches. The finest grove in the park is near Mount Conness, and the trail from the Tuolumne soda springs to the mountain runs through it. Many of the trees in this grove are three to four or five feet in diameter and about a hundred feet high.
The mountain hemlock is widely distributed from near the south extremity of the high Sierra northward along the Cascade Mountains of Oregon and Washington and the coast ranges of British Columbia to Alaska, where it was first discovered in 1827. Its northmost limit, so far as I have observed, is in the icy fiords of Prince William’s Sound in latitude 61, where it forms are forests at the level of the sea, growing tall and majestic on the banks of the great glaciers, waving in accord with the mountain winds and the thunder of the falling icebergs. Here as in the Sierra it is ineffably beautiful, the very loveliest evergreen in America.
Of the round-headed dicotyledonous trees in the park the most influential are the black and goldcup oaks. They occur in some parts of the main forest belt, scattered among the big pines like a heavier chaparral, but form extensive groves and reach perfect development only in the Yosemite valleys and flats of the main cañons. The California black oak ( Quercus Californica ) is one of the largest and most beautiful of the Western oaks, attaining under favorable conditions a height of sixty to a hundred feet, with a trunk three to seven feet in diameter, wide-spreading picturesque branches, and smooth lively green foliage handsomely scalloped, purple in the spring, yellow and red in autumn. It grows best in sunny open groves on ground covered with ferns, chokecherry, brier rose, rubus, mints, goldenrods, etc. Few, if any, of the famous oak groves of Europe, however extensive, surpass these in the size and strength and bright, airy beauty of the trees, the color and fragrance of the vegetation beneath them, the quality of the light that fills their leafy arches, and in the grandeur of the surrounding scenery. The finest grove in the park is in one of the little Yosemite valleys of the Tuolumne Cañon, a few miles above Hetch-Hetchy.
The mountain live-oak, or goldcup oak ( Quercus chrysolepis ), forms extensive groves on earthquake and avalanche taluses and terraces in cañons and Yosemite valleys, from about three to five thousand feet above the sea. In tough, sturdy, unwedgeable strength this is the oak of oaks. In general appearance it resembles the great live-oak of the Southern states. It has pale gray dark, a short, uneven, heavily buttressed trunk which usually divides a few feet above the ground into strong wide-reaching limbs, forming noble arches, and ending in an intricate maze of small branches and sprays, the outer ones frequently drooping in long tresses to the ground like those of the weeping willow, covered with small simple polished leaves, making a canopy broad and bossy, on which the sunshine falls in glorious brightness. The acorn cups are shallow, thick-walled, and covered with yellow fuzzy dust. The flowers appear in May and June with a profusion of pollened tresses, followed by the bronze-colored young leaves.
No tree in the park is a better measure of altitude. In cañons, at an elevation of four thousand, feet you may easily find a tree six or eight feet in diameter; and at the head of a side cañon, three thousand feet higher, up which you can climb in less than two hours, you find the knotty giant dwarfed to a slender shrub, with leaves like those of huckleberry bushes, still bearing acorns, and seemingly contented, forming dense patches of chaparral, on the top of which you may make your bed and sleep softly like a Highlander in heather. About a thousand feet higher it is still smaller, making fringes about a foot high around boulders and along seams in pavements and the brows of cañons, giving hand-holds here and there on cliffs hard to climb. The largest I have measured were from twenty-five to twenty-seven feet in girth, fifty to sixty feet high, and the spread of the limbs was about double the height.
The principal riverside trees are poplar, alder, willow, broad-leaved maple, and Nuttall’s flowering dogwood. The poplar (Populus trichocarpa), often called balm of Gilead from the gum on its buds, is a tall, stately tree, towering above its companions and gracefully embowering the banks of the main streams at an elevation of about four thousand feet. Its abundant foliage turns bright yellow in the fall, and the Indian-summer sunshine sifts through it in delightful tones over the slow-gliding waters when they are at their lowest ebb.
The flowering dogwood is brighter still in these brooding days, for every branch of its broad head is then a brilliant crimson flame. In the spring, when the streams are in flood, it is the whitest of trees, white as a snow bank with its magnificent flowers four to eight inches in width, making a wonderful show, and drawing swarms of moths and butterflies.
The broad-leaved maple is usually found in the coolest boulder-choked cañons, where the streams are gray and white with foam, over which it spreads its branches in beautiful arches from bank to bank, forming leafy tunnels full of soft green light and spray,—favorite homes of the water ousel. Around the glacier lakes, two or three thousand feet higher, the common aspen grows in fringing lines and groves which are brilliantly colored in autumn, reminding you of the color glory of the Eastern woods.
Scattered here and there or in groves the botanist will find a few other trees, mostly small,—the mountain mahogany, cherry, chestnut-oak, laurel, and nutmeg. The California nutmeg ( Tumion Californicum ) is a handsome evergreen, belonging to the yew family, with pale bark, prickly leaves, fruit like a green-gage plum, and seed like a nutmeg. One of the best groves of it in the park is at the Cascades below Yosemite.
But the noble oaks and all these rock-shading, stream-embowering trees are as nothing amid the vast abounding billowy forests of conifers. During my first years in the Sierra I was ever calling on everybody within reach to admire them, but I found no one half warm enough until Emerson came. I had reach his essays, and felt sure that of all men he would best interpret the sayings of these noble mountains and trees. Nor was my faith weakened when I met him in Yosemite. He seemed as serene as a sequoia, his head in the empyrean; and forgetting his age, plans, duties, ties of every sort, I proposed an immeasurable camping trip back in the heart of the mountains. He seemed anxious to go, but considerately mentioned his party. I said: “Never mind. The mountains are calling; run away, and let plans and parties and dragging lowland duties all gang tapsal-teerie. We’ll go up a cañon singing your own song, ‘Good-by, proud world! I’m going home, in divine earnest. Up there lies a new heaven and a new earth; let us go to the show.” But alas, it was too late,—too near the sundown of his life. The shadows were growing long, and he leaned on his friends. His party, full of indoor philosophy, failed to see the natural beauty and fullness of promise of my wild plan, and laughed at it in good-natured ignorance, as if it were necessarily amusing to imagine that Boston people might be led to accept Sierra manifestations of God at the price of rough camping. Anyhow, they would have none of it, and held Mr. Emerson to the hotels and trails.
After spending only five tourist days in Yosemite he was led away, but I saw him two days more; for I was kindly invited to go with the party as far as the Mariposa big trees. I told Mr. Emerson that I would gladly go to the sequoias with him, if he would camp in the grove. He consented heartily, and I felt sure that we would have at least one good wild memorable night around a sequoia camp-fire. Next day we rode through the magnificent forests of the Merced basin, and I kept calling his attention to the sugar pines, quoting his wood-notes, “Come listen what the pine tree saith,” etc., pointing out the noblest as kings and high priests, the most eloquent and commanding preachers of all the mountain forests, stretching forth their century-old arms in benediction over the worshiping congregations crowded about them. He gazed in devout admiration, saying but little, while his fine smile faded away.
Early in the afternoon, when we reached Clark’s Station, I was surprised to see the party dismount. And when I asked if we were not going up into the grove to camp they said: “No; it would never do to lie out in the night air. Mr. Emerson might take cold; and you know, Mr. Muir, that would be a dreadful thing.” In vain I urged, that only in homes and hotels were colds caught, that nobody ever was known to take cold camping in these woods, that there was not a single cough or sneeze in all the Sierra. Then I pictured the big climate-changing, inspiring fire I would make, praised the beauty and fragrance of sequoia flame, told how the great trees would stand about us transfigured in the purple light, while the stars looked down between the great domes; ending by urging them to come on and make an immortal Emerson night of it. But the house habit was not to be overcome, nor the strange dread of pure night air, though it is only cooled day air with a little dew in it. So the carpet dust and unknowable reeks were preferred. And to think of this being a Boston choice! Sad commentary on culture and the glorious transcendentalism.
Accustomed to reach whatever place I started for, I was going up the mountain alone to camp, and wait the coming of the party next day. But since Emerson was so soon to vanish, I concluded to stop with him. He hardly spoke a word all the evening, yet it was a great pleasure simply to be near him, warming in the light of his face as at a fire. In the morning we rode up the trail through a noble forest of pine and fir into the famous Mariposa Grove, and stayed an hour or two, mostly in ordinary tourist fashion,—looking at the biggest giants, measuring them with a tape line, ridding through prostrate fire-bored trunks, etc., though Mr. Emerson was alone occasionally, sauntering about as if under a spell. As we walked through a fine group, he quoted, “There were giants in those days,” recognizing the antiquity of the race. To commemorate his visit, Mr. Galen Clark, the guardian of the grove, selected the finest of the unnamed trees and requested him to give it a name. He named it Samoset, after the New England sachem, as the best that occurred to him.
The poor bit of measured time was soon spent, and while the saddles were being adjusted I again urged Emerson to stay. “You are yourself a sequoia,” I said. “Stop and get acquainted with your big brethren.” But he was past his prime, and was now as a child in the hands of his affectionate but sadly civilized friends, who seemed as full of old-fashioned conformity as of bold intellectual independence. It was the afternoon of the day and the afternoon of his life, and his course was now westward down all the mountains into the sunset. The party mounted and rode away in wondrous contentment, apparently, tracing the trail through ceanothus and dogwood bushes, around the bases of the big trees, up the slope of the sequoia basin, and over the divide. I followed to the edge of the grove. Emerson lingered in the rear of the train, and when he reached the top of the ridge, after all the rest of the party were over and out of sight, he turned his horse, took off his hat and waved me a last good-by. I felt lonely, so sure had I been that Emerson of all men would be the quickest to see the mountains and sing them. Gazing awhile on the spot where he vanished, I sauntered back into the heart of the grove, made a bed of sequoia plumes and ferns by the side of a stream, gathered a store of firewood, and then walked about until sundown. The birds, robins, thrushes, warblers, etc., that had kept out of sight, came about me, now that all was quiet, and made cheer. After sundown I built a great fire, and as usual had it all to myself. And though lonesome for the first time in these forests, I quickly took heart again,—the trees had not gone to Boston, nor the birds; and as I sat by the fire, Emerson was still with me in spirit, though I never again saw him in the flesh. He sent books and wrote, cheering me on; advised me not to stay too long in solitude. Soon he hoped that my guardian angel would intimate that my probation was at a close. Then I was to roll up my herbariums, sketches, and poems (though I never knew I had any poems), and come to his house; and when I tired of him and his humble surroundings, he would show me to better people.
But there remained many a forest to wander through, many a mountain and glacier to cross, before I was to see his Wachusett and Monadnock, Boston and Concord. It was seventeen years after our parting on the Wawona ridge that I stood beside his grave under a pine tree on the hill above Sleepy Hollow. He had gone to higher Sierras, and, as I fancied, was again waving his hand in friendly recognition.
