There is no absolute limit to the existence of any tree. Death is due to accidents, not, as that of animals, to the wearing out of organs. Only the leaves die of old age. Their fall is foretold in their structure; but the leaves are renewed every year, and so also are the essential organs wood, roots, bark, buds. Most of the Sierra trees die of disease, insects, fungi, etc., but nothing hurts the big tree. I never saw one that was sick or showed the slightest sign of decay. Barring accidents, it seems to be immortal. It is a curious fact that all the very old sequoias had lost their heads by lightning strokes. "All things come to him who waits." But of all living things, sequoia is perhaps the only one able to wait long enough to make sure of being struck by lightning.
So far as I am able to see at present only fire and the ax threaten the existence of these noblest of God's trees. In Nature's keeping they are safe, but through the agency of man destruction is making rapid progress, while in the work of protection only a good beginning has been made. The Fresno grove, the Tuolumne, Merced and Mariposa groves are under the protection of the Federal Government in the Yosemite National Park. So are the General Grant and Sequoia National Parks; the latter, established twenty-one years ago, has an area of 240 square miles and is efficiently guarded by a troop of cavalry under the direction of the Secretary of the Interior; so also are the small General Grant National Park, estatblished at the same time with an area of four square miles, and the Mariposa grove, about the same size and the small Merced and Tuolumne group. Perhaps more than half of all the big trees have been thoughtlessly sold and are now in the hands of speculators and mill men. It appears, therefore, that far the largest and important section of protected big trees is in the great Sequoia National Park, now easily accessible by rail to Lemon Cove and thence by a good stage road into the giant forest of the Kaweah and thence by rail to other parts of the park; but large as it is it should be made much larger. Its natural eastern boundary is the High Sierra and the northern and southern boundaries are the Kings and Kern Rivers. Thus could be included the sublime scenery on the headwaters of these rivers and perhaps nine-tenths of all the big trees in existence. All private claims within these bounds should be gradually extinguished by purchase by the Government. The big tree, leaving all its higher uses out of the count, is a tree of life to the dwellers of the plain dependent on irrigation, a never-failing spring, sending living waters to the lowland. For every grove cut down a stream is dried up. Therefore all California is crying, "Save the trees of the fountains." Nor, judging by the signs of the times, is it likely that the cry will cease until the salvation of all that is left of Sequoia gigantea is made sure.

The Flowers
Yosemite was all one glorious flower garden before plows and scythes and trampling, biting horses came to make its wide open spaces look like farmers' pasture fields. Nevertheless, countless flowers still bloom every year in glorious profusion on the grand talus slopes, wall benches and tablets, and in all the fine, cool side-cañons up to the rim of the Valley, and beyond, higher and higher, to the summits of the peaks. Even on the open floor and in easily-reached side-nooks many common flowering plants have survived and still make a brave show in the spring and early summer. Among these we may mention tall œnotheras, Pentstemon lutea, and P. Douglasii with fine blue and red flowers; Spraguea, scarlet zauschneria, with its curious radiant rosettes characteristic of the sandy flats; mimulus, eunanus, blue and white violets, geranium, columbine, erythraea, larkspur, collomia, draperia, gilias, heleniums, bahia, goldenrods, daisies, honeysuckle; heuchera, bolandra, saxifrages, gentians; in cool cañon nooks and on Clouds' Rest and the base of Starr King Dome you may find Primula suffrutescens, the only wild primrose discovered in California, and the only known shrubby species in the genus. And there are several fine orchids, habenaria, and cypripedium, the latter very rare, once common in the Valley near the foot of Glacier Point, and in a bog on the rim of the Valley near a place called Gentry's Station, now abandoned. It is a very beautiful species, the large oval lip white, delicately veined with purple; the other petals and the sepals purple, strap-shaped, and elegantly curled and twisted.
Of the lily family, fritillaria, smilacina, chlorogalum and several fine species of brodiæa, Ithuriel's spear, and others less prized are common, and the favorite calochortus, or Mariposa lily, a unique genus of many species, something like the tulips of Europe but far finer. Most of them grow on the warm foothills below the Valley, but two charming species, C. cœruleus and C. nudus, dwell in springy places on the Wawona road a few miles beyond the brink of the walls.
The snow plant (Sarcodes sanguinea) is more admired by tourists than any other in California. It is red, fleshy and watery and looks like a gigantic asparagus shoot. Soon after the snow is off the round it rises through the dead needles and humus in the pine and fir woods like a bright glowing pillar of fire. In a week or so it grows to a height of eight or twelve inches with a diameter of an inch and a half or two inches; then its long fringed bracts curl aside, allowing the twenty- or thirty-five-lobed, bell-shaped flowers to open and look straight out from the axis. It is said to grow up through the snow; on the contrary, it always waits until the ground is warm, though with other early flowers it is occasionally buried or half-buried for a day or two by spring storms. The entire plant–flowers, bracts, stem, scales, and roots–is fiery red. Its color could appeal to one's blood. Nevertheless, it is a singularly cold and unsympathetic plant. Everybody admires it as a wonderful curiosity, but nobody loves it as lilies, violets, roses, daisies are loved. Without fragrance, it stands beneath the pines and firs lonely and silent, as if unacquainted with any other plant in the world; never moving in the wildest storms; rigid as if lifeless, though covered with beautiful rosy flowers.
Far the most delightful and fragrant of the Valley flowers is the Washington lily, white, moderate in size, with from three- to ten-flowered racemes. I found one specimen in the lower end of the Valley at the foot of the Wawona grade that was eight feet high, the raceme two feet long, with fifty-two flowers, fifteen of them open; the others had faded or were still in the bud. This famous lily is distributed over the sunny portions of the sugar-pine woods, never in large meadow-garden companies like the large and the small tiger lilies (pardalinum and parvum), but widely scattered, standing up to the waist in dense ceanothus and manzanita chaparral, waving its lovely flowers above the blooming wilderness of brush, and giving their fragrance to the breeze. It is now becoming scarce in the most accessible parts of its range on account of the high price paid for its bulbs by gardeners through whom it has been distributed far and wide over the flower-loving world. For, on account of its pure color and delicate, delightful fragrance, all lily lovers at once adopted it as a favorite.
The principal shrubs are manzanita and ceanothus, several species of each, azalea, Rubus nutkanus, brier rose, choke-cherry philadelphus, calycanthus, garrya, rhamnus, etc.
The manzanita never fails to attract particular attention. The species common in the Valley is usually about six or seven feet high, round-headed with innumerable branches, red or chocolate-color bark, pale green leaves set on edge, and a rich profusion of small, pink, narrow-throated, urn-shaped flowers, like those of arbutus. The knotty, crooked, angular branches are about as rigid as bones, and the red bark is so thin and smooth on both trunk and branches, they look as if they had been peeled and polished and painted. In the spring large areas on the mountain up to a height of eight or nine thousand feet are brightened with the rosy flowers, and in autumn with their red fruit. The pleasantly acid berries, about the size of peas, look like little apples, and a hungry mountaineer is glad to eat them, though half their bulk is made up of hard seeds. Indians, bears, coyotes, foxes, birds and other mountain people live on them for weeks and months. The different species of ceanothus usually associated with manzanita are flowery fragrant and altogether delightful shrubs, growing in glorious abundance, not only in the Valley, but high up in the forest on sunny or half-shaded ground. In the sugar-pine woods the most beautiful species is C. integerrimus, often called Californian lilac, or deer brush. It is five or six feet high with slender branches, glossy foliage, and abundance of blue flowers in close, showy panicles. Two species, C. prostrates and C. procumbens, spread smooth, blue-flowered mats and rugs beneath the pines, and offer fine beds to tired mountaineers. The commonest species, C. cordulatus, is most common in the silver-fir woods. It is white-flowered and thorny, and makes dense thickets of tangled chaparral, difficult to wade through or to walk over. But it is pressed flat every winter by ten or fifteen feet of snow. The western azalea makes glorious beds of bloom along the river bank and meadows. In the Valley it is from two to five feet high, has fine green leaves, mostly hidden beneath its rich profusion of large, fragrant white and yellow flowers, which are in their prime in June, July and August, according to the elevation, ranging from 3000 to 6000 feet. Near the azalea-bordered streams the small wild rose, resembling R. blanda, makes large thickets deliciously fragrant, especially on a dewy morning and after showers. Not far from these azalea and rose gardens, Rubus nutkanus covers the ground with broad, soft, velvety leaves, and pure-white flowers as large as those of its neighbor and relative, the rose, and much finer in texture, followed at the end of summer by soft red berries good for everybody. This is the commonest and the most beautiful of the whole blessed, flowery, fruity Rubus genus.
There are a great many interesting ferns in the Valley and about it. Naturally enough the greater number are rock ferns–pellæa, cheilanthes, polypodium, adiantum, woodsia, cryptogramma, etc., with small tufted fronds, lining cool glens and fringing the seams of the cliffs. The most important of the larger species are woodwardia, aspidium, asplenium, and, above all, the common pteris. Woodwardia radicans is a superb, broad-shouldered fern five to eight feet high, growing in vase-shaped clumps where tile ground is nearly level and on some of the benches of the north wall of the Valley where it is watered by a broad trickling stream. It thatches the sloping rocks, frond overlapping frond like roof shingles. The broad-fronded, hardy Pteris aquilina, the commonest of ferns, covers large areas on the floor of the Valley. No other fern does so much for the color glory of autumn, with its browns and reds and yellows, even after lying dead beneath the snow all winter. It spreads a rich brown mantle over the desolate ground in the spring before the grass has sprouted, and at the first touch of sun-heat its young fronds come rearing up full of faith and hope through the midst of the last year's ruins.
Of the five species of pellæa, P. Breweri is the hardiest as to enduring high altitudes and stormy weather and at the same time it is the most fragile of the genus. It grows in dense tufts in the clefts of storm-beaten rocks, high up on the mountain-side on the very edge of the fern line. It is a handsome little fern about four or five inches high, has pale-green pinnate fronds, and shining bronze-colored stalks about as brittle as glass. Its companions on the lower part of its range are Cryptogramma acrostichoides and Phegopteris alpestris, the latter with soft, delicate fronds, not in the least like those of Rock fern, though it grows on the rocks where the snow lies longest. Pellaea Bridgesii, with blue-green, narrow, simply-pinnate fronds, is about the same size as Breweri and ranks next to it as a mountaineer, growing in fissures, wet or dry, and around the edges of boulders that are resting on glacier pavements with no fissures whatever. About a thousand feet lower we find the smaller, more abundant P. densa on ledges and boulder-strewn, fissured pavements, watered until late in summer from oozing currents, derived from lingering snowbanks. It is, or rather was, extremely abundant between the foot of the Nevada and the head of the Vernal Fall, but visitors with great industry have dug out almost every root, so that now one has to scramble in out-of-the-way places to find it. The three species of Cheilanthes in the Valley–C. californica, C. gracillima, and myriophylla, with beautiful two-to-four-pinnate fronds, an inch to five inches long, adorn the stupendous walls however dry and sheer. The exceedingly delicate californica is so rare that I have found it only once. The others are abundant and are sometimes accompanied by the little gold fern, Gymnogramme triangularis, and rarely by the curious little Botrychium simplex, some of them less than an inch high. The finest of all the rock ferns is Adiantum pedatum, lover of waterfalls and the finest spray-dust. The homes it loves best are over-leaning, cave-like hollows, beside the larger falls, where it can wet its fingers with their dewy spray. Many of these moss-lined chambers contain thousands of these delightful ferns, clinging to mossy walls by the slightest hold, reaching out their delicate finger-fronds on dark, shining stalks, sensitive and tremulous, throbbing in unison with every movement and tone of the falling water, moving each division of the frond separately at times, as if fingering the music.
May and June are the main bloom-months of the year. Both the flowers and falls are then at their best. By the first of August the midsummer glories of the Valley are past their prime. The young birds are then out of their nests. Most of the plants have gone to seed; berries are ripe; autumn tints begin to kindle and burn over meadow and grove, and a soft mellow haze in the morning sunbeams heralds the approach of Indian summer. The shallow river is now at rest, its flood-work done. It is now but little more than a series of pools united by trickling, whispering currents that steal softly over brown pebbles and sand with scarce an audible murmur. Each pool has a character of its own and, though they are nearly currentless, the night air and tree shadows keep them cool. Their shores curve in and out in bay and promontory, giving the appearance of miniature lakes, their banks in most places embossed with brier and azalea, sedge and grass and fern; and above these in their glory of autumn colors a mingled growth of alder, willow, dogwood and balm-of-Gilead; mellow sunshine overhead, cool shadows beneath; light filtered and strained in passing through the ripe leaves like that which passes through colored windows. The surface of the water is stirred, perhaps, by whirling water-beetles, or some startled trout, seeking shelter beneath fallen logs or roots. The falls, too, are quiet; no wind stirs, and the whole Valley floor is a mosaic of greens and purples, yellows and reds. Even the rocks seem strangely soft and mellow, as if they, too, had ripened.

The Birds
The songs of the Yosemite winds and waterfalls are delightfully enriched with bird song, especially in the nesting time of spring and early summer. The most familiar and best known of all is the common robin, who may be seen every day, hopping about briskly on the meadows and uttering his cheery, enlivening call. The black-headed grosbeak, too, is here, with the Bullock oriole, and western tanager, brown song-sparrow, hermit thrush, the purple finch,–a fine singer, with head and throat of a rosy-red hue,–several species of warblers and vireos, kinglets, flycatchers, etc.
But the most wonderful singer of all the birds is the water-ouzel that dives into foaming rapids and feeds at the bottom, holding on in a wonderful way, living a charmed life.
Several species of humming-birds are always to be seen, darting and buzzing among the showy flowers. The little red-bellied nuthatches, the chickadees, and little brown creepers, threading the furrows of the bark of the pines, searching for food in the crevices. The large Steller's jay makes merry in the pine-tops; flocks of beautiful green swallows skim over the streams, and the noisy Clarke's crow may oftentimes be seen on the highest points around the Valley; and in the deep woods beyond the walls you may frequently hear and see the dusky grouse and the pileated woodpecker, or woodcock almost as large as a pigeon. The junco or snow-bird builds its nest on the floor of the Valley among the ferns; several species of sparrow are common and the beautiful lazuli bunting, a common bird in the underbrush, flitting about among the azalea and ceanothus bushes and enlivening the groves with his brilliant color; and on gravelly bars the spotted sandpiper is sometimes seen. Many woodpeckers dwell in the Valley; the familiar flicker, the Harris woodpecker and the species which so busily stores up acorns in the thick bark of the yellow pines.
The short, cold days of winter are also sweetened with the music and hopeful chatter of a considerable number of birds. No cheerier choir ever sang in snow. First and best of all is the water-ouzel, a dainty, dusky little bird about the size of a robin, that sings in sweet fluty song all winter and all summer, in storms and calms, sunshine and shadow, haunting the rapids and waterfalls with marvelous constancy, building his nest in the cleft of a rock bathed in spray. He is not web-footed, yet he dives fearlessly into foaming rapids, seeming to take the greater delight the more boisterous the stream, always as cheerful and calm as any linnet in a grove. All his gestures as he flits about amid the loud uproar of the falls bespeak the utmost simplicity and confidence–bird and stream one and inseparable. What a pair! yet they are well related. A finer bloom than the foam bell in an eddying pool is this little bird. We may miss the meaning of the loud-resounding torrent, but the flute-like voice of the bird–only love is in it.
A few robins, belated on their way down from the upper Meadows, linger in the Valley and make out to spend the winter in comparative comfort, feeding on the mistletoe berries that grow on the oaks. In the depths of the great forests, on the high meadows, in the severest altitudes, they seem as much at home as in the fields and orchards about the busy habitations of man, ascending the Sierra as the snow melts, following the green footsteps of Spring, until in July or August the highest glacier meadows are reached on the summit of the Range. Then, after the short summer is over, and their work in cheering and sweetening these lofty wilds is done, they gradually make their way down again in accord with the weather, keeping below the snow-storms, lingering here and there to feed on huckleberries and frost-nipped wild cherries growing on the upper slopes. Thence down to the vineyards and orchards of the lowlands to spend the winter; entering the gardens of the great towns as well as parks and fields, where the blessed wanderers are too often slaughtered for food–surely a bad use to put so fine a musician to; better make stove wood of pianos to feed the kitchen fire.
The kingfisher winters in the Valley, and the flicker and, of course, the carpenter woodpecker, that lays up large stores of acorns in the bark of trees; wrens also, with a few brown and gray linnets, and flocks of the arctic bluebird, making lively pictures among the snow-laden mistletoe bushes. Flocks of pigeons are often seen, and about six species of ducks, as the river is never wholly frozen over. Among these are the mallard and the beautiful woodduck, now less common on account of being so often shot at. Flocks of wandering geese used to visit the Valley in March and April, and perhaps do so still, driven down by hunger or stress of weather while on their way across the Range. When pursued by the hunters I have frequently seen them try to fly over the walls of Lee Valley until tired out and compelled to re-alight. Yosemite magnitudes seem to be as deceptive to geese as to men, for after circling to a considerable height and forming regular harrow-shaped ranks they would suddenly find themselves in danger of being dashed against the face of the cliff, much nearer the bottom than the top. Then turning in confusion with loud screams they would try again and again until exhausted and compelled to descend. I have occasionally observed large flocks on their travels crossing the summits of the Range at a height of 12,000 to 13,000 feet above the level of the sea, and even in so rare an atmosphere as this they seemed to be sustaining themselves without extra effort. Strong, however, as they are of wind and wing, they cannot fly over Yosemite walls, starting from the bottom.
A pair of golden eagles have lived in the Valley ever since I first visited it, hunting all winter along the northern cliffs and down the river cañon. Their nest is on a ledge of the cliff over which pours the Nevada Fall. Perched on the top of a dead spar, they were always interested observers of the geese when they were being shot at. I once noticed one of the geese compelled to leave the flock on account of being sorely wounded, although it still seemed to fly pretty well. Immediately the eagles pursued it and no doubt struck it down, although I did not see the result of the hunt. Anyhow, it flew past me up the Valley, closely pursued.
One wild, stormy winter morning after five feet of snow had fallen on the floor of the Valley and the flying flakes driven by a strong wind still thickened the air, making darkness like the approach of night, I sallied forth to see what I might learn and enjoy. It was impossible to go very far without the aid of snow-shoes, but I found no great difficulty in making my way to a part of the river where one of my ouzels lived. I found him at home busy about his breakfast, apparently unaware of anything uncomfortable in the weather. Presently he flew out to a stone against which the icy current was beating, and turning his back to the wind, sang as delightfully as a lark in springtime.
After spending an hour or two with my favorite, I made my way across the Valley, boring and wallowing through the loose snow, to learn as much as possible about the way the other birds were spending their time. In winter one can always find them because they are then restricted to the north side of the Valley, especially the Indian Cañon groves, which from their peculiar exposure are the warmest.
I found most of the robins cowering on the lee side of the larger branches of the trees, where the snow could not fall on them, while two or three of the more venturesome were making desperate efforts to get at the mistletoe berries by clinging to the underside of the snow-crowned masses, back downward, something like woodpeckers. Every now and then some of the loose snow was dislodged and sifted down on the hungry birds, sending them screaming back to their companions in the grove, shivering and muttering like cold, hungry children.
Some of the sparrows were busy scratching and pecking at the feet of the larger trees where the snow had been shed off, gleaning seeds and benumbed insects, joined now and then by a robin weary of his unsuccessful efforts to get at the snow-covered mistletoe berries. The brave woodpeckers were clinging to the snowless sides of the larger boles and overarching branches of the camp trees, making short flights from side to side of the grove, pecking now and then at the acorns they had stored in the bark, and chattering aimlessly as if unable to keep still, evidently putting in the time in a very dull way. The hardy nuthatches were threading the open furrows of the barks in their usual industrious manner and uttering their quaint notes, giving no evidence of distress. The Steller's jays were, of course, making more noise and stir than all the other birds combined; ever coming and going with loud bluster, screaming as if each had a lump of melting sludge in his throat, and taking good care to improve every opportunity afforded by the darkness and confusion of the storm to steal from the acorn stores of the woodpeckers. One of the golden eagles made an impressive picture as he stood bolt upright on the top of a tall pine-stump, braving the storm, with his back to the wind and a tuft of snow piled on his broad shoulders, a monument of passive endurance. Thus every storm-bound bird seemed more or less uncomfortable, if not in distress. The storm was reflected in every gesture, and not one cheerful note, not to say song, came from a single bill. Their cowering, joyless endurance offered striking contrasts to the spontaneous, irrepressible gladness of the ouzel, who could no more help giving out sweet song than a rose sweet fragrance. He must sing, though the heavens fall.
