Yes; and not unfamiliar the knowledge that with the coming of civilization the grasses and the wild flowers perish, the forest falls and its place is taken by brambles, the mountains are blasted in the search for minerals, the plains are broken by the plow and the soil is gradually washed into the rivers. Last of all, when the forests have gone the rains cease falling, the streams dry up, the ground parches and yields no life, and the artificial desert—the desert made by the tramp of human feet—begins to show itself, Yes; everyone must have cast a backward glance and seen Nature’s beauties beaten to ashes under the successive marches of civilization. The older portions of the earth show their desolation plainly enough, and the ascending smoke and dust of the ruin have even tainted the air and dimmed the sunlight. Indeed, I am not speaking figuratively or extravagantly. We have often heard of ‘‘ Sunny Italy” or the “clear light” of Egypt, but be- lieve me there is no sunlight there compared with that which falls upon the upper peaks of EE —— Lc hm niente PREFACE-DEDICATION ix the Sierra Madre or the uninhabitable wastes of the Colorado Desert. Pure sunlight requires for its existence pure air, and the Old World has little of it left. When you are in Rome again and stand upon that hill where all good roman- ticists go at sunset, look out and notice how dense is the atmosphere between you and St. . Peter’s dome. That same thick air is all over Europe, all around the Mediterranean, even over in Mesopotamia and by the banks of the Ganges. It has been breathed and burned and battle-smoked for ten thousand years. Ride up and over the high table-lands of Montana—one can still ride there for days without seeing a trace of humanity—and how clear and scentless, how absolutely intangible that sky-blown sun- shot atmosphere! You breathe it without feel- ing it, you see through it a hundred miles and the picture is not blurred by it. It is just so with Nature’s color. True enough, there is much rich color at Venice, at Cairo, at Constantinople. Its beauty need not be denied ; and yet it is an artificial, a chemical color, caused by the disintegration of matter— the decay of stone, wood, and iron torn from the neighboring mountains. It is Nature after a poor fashion—Nature subordinated to the will x PREFACE-—DEDICATION of man. Once more ride over the enchanted mesas of Arizona at sunrise or at sunset, with the ragged mountains of Mexico to the south of you and the broken spurs of the great sierra round about you ; and all the glory of the old shall be as nothing to the gold and purple and burning crimson of this new world. You will not be surprised then if, in speaking of desert, mesa and mountain I once more take you far beyond the wire fence of civilization to those places (unhappily few now) where the trail is unbroken and the mountain peak un- blazed. I was never over-fond of park and garden nature-study. If we would know the great truths we must seek them at the source. The sandy wastes, the arid lands, the porphyry mountain peaks may be thought profitless places for pilgrimages ; but how often have you and I, and that one we both loved so much, found beauty in neglected marshes, in wintry forests, and in barren hill-sides! The love of Nature is after all an acquired taste. One be- gins by admiring the Hudson-River landscape and ends by loving the desolation of Sahara. Just why or how the change would be difficult to explain. You cannot always dissect a taste or a passion. Nor can you pin Nature to a PREFACE—DEDICATION xi board and chart her beauties with square and compasses. One can give his impression and but little more. Perhaps I can tell you some- thing of what I have seen in these two years of wandering; but I shall never be able to tell you the grandeur of these mountains, nor the glory of color that wraps the burning sands at their feet. We shoot arrows at the sun in vain; vet still we shoot. And so it is that my book is only an excuse for talking about the beautiful things in this desert world that stretches down the Pacific Coast, and across Arizona and Sonora. The desert has gone a-begging for a word of praise these many years. It never had a sacred poet ; it has in me only a lover. ButI trust that you, and the nature-loving public you represent, will accept this record of the Colorado and the Mojave as at least truthful. Given the facts perhaps the poet with his fancies will come | hereafter. JOHN C. VAN DYKE. La Norra VERDE Fepsruary, 1901. i Yn, ; ae: LIBRARY °2\ SEP 12 1907 2 CONTENTS CHapteR I.

For days I have been watch- ing them change color at sunset—watching the canyons shift into great slashes of blue and purple shadow, and the ridges fame with edg- ings of glittering fire. They are lonesome look- ing mountains lying off there by themselves on the plain, so still, so barren, so blazing hot under the sun. Forsaken of their kind, one might not inappropriately call them the “ Lost Mountains ”—the surviving remnant no doubt of some noble range that long centuries ago was beaten by wind and rain into desert sand. And yet before one gets to them they may prove quite formidable heights, with precipitous sides and unsurmountable tops. Who knows? Not those with whom I am stopping, for they have 1 Desert — mountains THE DESERT Unknown ranges. Early morning on the desert. Air illu- sions. not been there. They do not even know the name of them. The Papagoes leave them alone because there is no game in them. Evidently they are considered unimportant hills, no- body’s hills, no man’s range; but nevertheless I am off for them in the morning at daylight. I ride away through the thin mesquite and the little adobe ranch house is soon lost to view. The morning is still and perfectly clear. The stars have gone out, the moon is looking pale, the deep blue is warming, the sky is lightening with the coming day. How cool and crystalline the air! Ina few hours the great plain will be almost like a fiery furnace under the rays of the summer sun, but now it is chilly. And in a few hours there will be rings and bands and scarves of heat set wavering across the waste upon the opalescent wings of the mirage ; but now the air is so clear that one can see the breaks in the rocky face of the mountain range, though it is fully twenty miles away. It may be further. Who of the desert has not spent his day riding at a mountain and never even reaching its base? This isa land of illu- sions and thin air. The vision is so cleared at times that the truth itself is deceptive. But I shall ride on for several hours. If, by twelve THE APPROACH o’clock, the foot hills are not reached, I shall turn back. The summer heat has withered everything except the mesquite, the palo verde,* the grease-wood, and the various cacti. Under foot there is a little dry grass, but more often patches of bare gravel and sand rolled in shal- low beds that course toward the large valleys. In the draws and flat places the fine sand les thicker, is tossed in wave forms by the wind, and banked high against clumps of cholla or prickly pear. In the wash-outs and over the cut banks of the arroyos it is sometimes heaped in mounds and crests like driven snow. It blows here along the boundary line between Arizona and Sonora almost every day ; and the tailing of the sands behind the bushes shows that the prevailing winds are from the Gulf region. A cool wind? Yes, but only by com- parison with the north wind. When you feel it on your face you may think it the breath of some distant volcano. How pale-blue the Lost Mountains look under the growing light. Iam watching their edges develop into broken barriers of rock, and * The use of Spanish names is compulsory. There are no English equivalents. Sand Forms in the valleys. Winds of the desert. THE DESERT Sun shafts. The beauty of sunlight. even as I watch the tallest tower of all is struck with a bright fawn color. It is the high point to catch the first shaft of the sun. Quickly the light spreads downward until the whole ridge is tinged by it, and the abrupt sides of porphyry begin to glow under it. It is not long before great shafts of light alternating with shadow stretch down the plain ahead of me. The sun is streaming through the tops of the eastern mountains and the sharp pointed pinnacles are cutting shadows in the broad beam of light. That beam of light! Was there ever any- thing so beautiful! How it flashes its color through shadow, how it gilds the tops of the mountains and gleams white on the dunes of the desert! In any land what is there more glorious than sunlight! Even here in the desert, where it falls fierce and hot as a rain of meteors, it is the one supreme beauty to which all things pay allegiance. The beast and the bird are not too fond of its heat and as soon as the sun is high in the heavens they seek cover in the canyons; but for all that the chief glory of the desert is its broad blaze of omnipresent light. Yes, there is animal and bird life here though it is not always apparent unless you look for it. THE APPROACH Wrens and linnets are building nests in the cholla, and finches are singing from the top of the sahuaro.* There are plenty of reptiles, rabbits and ground squirrels quietly slipping out of your way; and now that the sun is up you can see a long sun-burned slant-of-hair trotting up yonder divide and casting an appre- hensive head from side to side as he moves off. It is not often that the old gray wolf shows himself to the traveller. He is usually up in the mountains before sunrise. And seldom now does one see the desert antelope along the mesas, and yet off to the south you can see patches of white that come and go almost like flashing mirrorsin thesun. They are stragglers from some band that have drifted up from cen- tral Sonora. No; they are not far away. A little mirage is already forming over that portion of the mesa and makes them look more distant than they are in reality. You can be deceived on the desert by the nearness of things quite as often as by their remoteness. These desert mountains have a fashion of ap- pearing distant until you are almost up to them. Then they seem to give up the game of decep- tion and come out of their hiding-places. It is * Properly Saguaro. Desert life. Antelope. The Lost Mountains THE DESERT Mountain walls. The ascent. Deer trails. just so with the mountains toward which I am riding. After several hours they seem to rise up suddenly in front of me and I am at their base. They are not high—perhaps fifteen hundred feet. The side near me is precipitous rock, weather-stained to a reddish-black. A ride around the bases discloses an almost com- plete perpendicular wall, slanting off half way down the sides into sloping beds of bowlders that have been shaken loose from the upper strata. A huge cleft in the western side—half barranca half canyon—seems to suggest a way to the summit. The walking up the mountain is not the best in the world. It is over splintered rock, step- ping from stone to stone, creeping along the backbone of bowlders, and worrying over rows of granite blocks. Presently the course seems to slip into a diagonal—a winding up and around the mountain—and ahead of me the stones begin to look peculiar, almost familiar. There seems to be a trail over the ledges and through the broken blocks; but what should make a trail up that deserted mountain ? Mule-deer travelling toward the summit to lie down in the heat of the day ? It is possible. The track of a band of deer soon becomes a o~, SRP R SE SST en te ete eS Ay 0g =n eal SS Sn eee : : 7 aC re . THE APPROACH beaten path, and animals are just as fond of a good path as humanity. By a strange coin- cidence at this very moment the sharp-toed print of a deer’s hoof appears in the ground before me. But it looks a little odd. The im- pression is so clear cut that I stoop to examine it. It is with no little astonishment that I find it sunk in stone instead of earth—petrified in rock and overrun with silica. The bare sug- gestion gives one pause. How many thousands of years ago was that impression stamped upon the stone? By what strange chance has it survived destruction? And while it remains quite perfect to-day—the vagrant hoof-mark of a desert deer—what has become of the once carefully guarded footprints of the Sargons, the Pharaohs and the Cesars? With what contempt Nature sometimes plans the survival of the least fit, and breaks the conqueror on his shield ! Further up the mountain the deer-trail theory is abandoned—at least so far as recent times are concerned. The stones are worn too smooth, the larger ones have been pushed aside by something more intelligent than a mule-deer’s hoof ; and in one place the trail seems to have been built up on the descending side. ‘There is Footprints, The stone path. THE DESERT Following the trail. Defensive walls. The summit, not the slightest evidence, either by rub upon the rocks, or overturned stones, or scrape in the gravel, that any living thing has passed up this pathway for many years; and yet the trail is a distinct line of lighter colored stone stretch- ing ahead of me. It is a path worn in the rocks, and there is no grass or vine or weed to obliterate it. It leads on and up to the saddle of the mountain. ‘There is a crevasse or chasm breaking through this saddle which might have been bridged at one time with mesquite trunks, but is now to be leaped if one would reach the summit. It is narrow only in one place and this is just where the trail happens to run. Across it, on the upper side, there is a horse- shoe shaped enclosure of stone. It is only a few feet in diameter, and the upper layers of stone have fallen; but the little wall still stands as high as one’s waist. Could this have been a sentinel box used to guard the passage of the trail at this place ? Higher and still higher until at last the mountain broadens into a flat top. i am so eager to gain the height and am expecting so much that at first I overlook what is before me. Gradually I make out along parapet of loose stone on the trail side of the mountain which a THE APPROACH joins on to steep cliffs on the other sides. A conclusion is instantly jumped at, for the im- agination will not make haste slowly under such circumstances. These are the ruins of a once fortified camp. I wander about the flat top of the mountain and slowly there grows into recognizable form a great rectangle enclosed by large stones placed about two feet apart. There is no doubt about the square and in one corner of it there seems an elevated mound covered with high-piled stones that would indicate a place for burials. But not a trace of pottery or arrow-heads ; and about the stones only faint signs of fire which might have come from volcanic actionas readily as from domestic hearths. Upon the side of one of the large rocks are some characters in red ochre ; and on the ground near a pot-hole in the rock, something that the imagination might torture into a rude pestle for grinding maize. The traces of human activity are slight. Nat- ure has been wearing them away and reclaim- ing her own on the mountain top. Grease- wood is growing where once a floor was beaten hard as iron by human feet ; out of the burial mound rises a giant sahuaro whose branching The fortified camp. Nature's reclama- trons. 10 THE DESERT Mountain- dwellers. Invading hosts. arms give the look of the cross; and beside the sahuaro rests a tall yucca with four feet of clustering bellflowers swinging from its top. And who were they who built these stone walls, these primitive entrenchments? When and where did they come from and what brought them here? The hands that executed this rough work were certainly untrained. Indians ? Very likely. Perhaps some small band that had taken up a natural defence in the mountains because too feeble in numbers to fight in the open. Here from this lookout they could watch the country for a hundred miles around. Here the scouts could see far away the thin string of foemen winding snake-like over the ridges of the desert, could see them grow in size and count their numbers, could look down upon them at the foot of the mountain and yell back defiance to the challenge coming up the steep sides. Brave indeed the invaders that would pluck the eagles from that aerie nest! Climb- ing a hill against a shower of arrows, spears, and bowlders is to fight at a terrible disad- vantage. Starve them out? Yes; but the ones at the bottom would starve as quickly as those at the top. Cut off their water supply? Yes; but Deh THE APPROACH 11 where did either besieged or besieger get water? If there was ever a spring in the mountain it long ago dried up, for there is no trace of it to- day. Possibly the mountain-dwellers knew of some arroyo where by digging in the sand they could get water. And possibly they carried it in ollas up the stone trail to their mountain home where they stored it in the rocks against the wrath of a siege to come. No doubt they took thought for trouble, and being native to the desert they could stand privation better - than their enemies. How long ago did that aboriginal band come trailing over these trackless deserts to find and make a home in a barren mountain standing in a bed of sand? Whocan tell? A geologist might make the remains of their fort an il- lustration of the Stone Age and talk of un- known centuries; an iconoclast might claim that it was merely a Mexican corral built to hide stolen horses; but a plain person of the southwest would say that it was an old Indian camp. The builders of the fortification and the rectangle worked with stone because there was no other material. The man of the Stone Age exists to-day contemporary with civilized man. Possibly he always did. And it may be that Water and Sood sup- plies. The abo- rigines. 12 THE DESERT Historic periods. The open desert, Perception of beauty. some day Science will conclude that historic periods do not invariably happen, that there is not always a sequential evolution, and that the white race does not necessarily require a flat- headed mass of stupidity for an ancestor. But what brought them to seek a dwelling place in the desert ? Were they driven out from the more fertile tracts? Perhaps. Did they find this a country where game was plentiful and the conditions of life comparatively easy ? It is possible. Or was it that they loved the open country, the hot sun, the treeless wastes, the great stretches of mesa, plain and valley ? Ah; that is more than likely. Mankind has always loved the open plains. He is like an antelope and wishes to see about him in all di- rections. Perhaps, too, he was born with a pre- dilection for ‘‘the view,” but that is no easy matter to prove. It is sometimes assumed that humanity had naturally a sense and a feeling for the beautiful because the primitives deco- rated pottery and carved war-clubs and totem- posts. Again perhaps ; but from war-clubs and totem-posts to sunsets and mountain shadows —the love of the beautiful in nature—is a very long hark. The peons and Indians in Sonora cannot see the pinks and purples in the moun- THE APPROACH 13 tain shadows at sunset. ‘They are astonished at your question for they see nothing but moun- tains. And you may vainly exhaust ingenuity trying to make a Pagago see the silvery sheen of the mesquite when the low sun is streaming across its tops. He sees only mesquite—the same dull mesquite through which he has chased rabbits from infancy. No; it is not likely that the tribe ever chose this abiding place for its scenery. A sensitive feeling for sound, or form, or color, an impres- sionable nervous organization, do not belong to the man with the hoe, much less to the man with the bow. It is to be feared that they are indicative of some physical degeneration, some decline in bone and muscle, some abnormal development of the emotional nature. They _ travel side by side with high civilization and are the premonitory symptoms of racial decay. But are we correct in assuming that because the red man does not see a colored shadow therefore he is blind to every charm and sub- limity of nature ? These mountain-dwellers, always looking out from their height, must have seen and re- marked the large features of the desert—the great masses of form, the broad blocks of color. Sense of beauty. Mountain oe view. ” 14 THE DESERT The desert colors. Looking down to the desert. They knew the long undulations of the valley- plain were covered with sharp, broken rock, but from this height surely they must have noticed how soft as velvet they looked, how smoothly they rolled from one into another, how perfect- ly they curved, how symmetrically they waved. And the long lines of the divides, lessening to the west—their ridges of grease-wood showing a peculiar green like the crests of sea-waves in storm—did they not see them ? Did they not look down on the low neighboring hills and know that they were pink, terra-cotta, orange- colored—all the strange hues that may be com- pounded of clay and mineral—with here and there a crowning mass of white quartz or a far- extending outcrop of shale stained blue and green with copper? Doubtless, a wealth of color and atmospheric effect was wasted upon the aboriginal retina; but did it not take note of the deep orange sunsets, the golden fringed heaps of cumulus, and the tongues of fire that curled from every little cirrus cloud that lin- gered in the western sky? And how often they must have looked out and down to the great basin of the desert where cloud and sky, mountain and mesa, seemed to dissolve into a pink mist! It was not an un- THE APPROACH 15 known land to them and yet it had its terrors. Tradition told that the Evil Spirit dwelt there, and it was his hot breath that came up every morning on the wind, scorching and burning the brown faces of the mountain-dwellers ! Fire !—he dwelt in fire. Whence came all the fierce glow of sunset down over that desert if it was not the reflection from his dwelling place ? The very mountain peaks flared red at times, and in the old days there were rivers of fire. The petrified waves and eddies of those rivers were still visible in the lava streams. Were there not also great flames beneath the sands that threw up hot water and boiled great vol- canoes of mud ? And along the base of many a cliff were there not jets of steam and smoke blown out from the heart of the mountains ? It was a land of fire. No food, no grass, no water. There were places in the canyons where occasionally a little stream was found forcing itself up through the rock; but frequently it was salt or, worse yet, poisoned with copper or arsenic. How often the tribe had lost from its numbers—slain by the heat and drought in that waste! More than once the bodies had been found by crossing bands and always the same tale was told. The victims were half The land of Jire. Drought and heat. 16 THE DESERT Desert mystery. Sand and gypsum. Sand- whirls. buried in sand, not decayed, but withered like the grass on the lomas. Mystery—a mystery as luminous and yet as impenetrable as its own mirage—seemed always hanging over that low-lying waste. It was a vast pit dug under the mountain bases. The mountains themselves were bare crags of fire in the sunlight, and the sands of the pit grew only cactus and grease-wood. There were tracts where nothing at all grew—miles upon miles of absolute waste with the pony’s feet breaking through an alkaline crust. And again, there were dry lakes covered with silt ; and vast beds of sand and gypsum, white as snow and fine as dust. The pony’s feet plunged in and came out leaving no trail. The surface smoothed over as though it were water. Fifty miles away one could see the desert sand-whirls moving slowly over the beds in tall columns two thousand feet high and shining like shafts of marble in the sunlight. How majestically they moved, their feet upon earth, their heads towering into the sky! And then the desert winds that raised at times such furious clouds of sand! All the air shone like gold-dust and the sun turned red as blood. Ah! what a stifling sulphureous THE APPROACH 17 air! Even on the mountain tops that heavy air could be felt, and down in the desert itself the driving particles of sand cut the face and hands like blizzard-snow. The ponies could not be made to face it. They turned their backs to the wind and hung their heads be- tween their fore feet. And how that wind roared and whistled through the thin grease- wood! The scrubby growths leaned and bent in the blast, the sand piled high on the trunks ; and nothing but the enormous tap-roots kept them from being wrenched from the earth. And danger always followed the high winds. They blew the sands in clouds that drifted full and destroyed the trails. In a single night they would cover up a water hole, and in a few days fill in an arroyo where water could be got by digging. The sands drove like breakers on a beach, washing and wearing everything up to the bases of the mountains. And the fine sand reached still higher. It whirled up the canyons and across the saddles, it eddied around the enormous taluses, it even flung itself upon the face walls of the mountain and left the smoothing marks of its fingers upon the sharp pinnacles of the peak. It was in winter when the winds were fiercest. Desert storms, Drift of sand. 18 THE DESERT Winter cold. Snow on desert. Sea and sand. With them at times came a sharp cold, the more biting for the thin dry air of the desert. All the warmth seemed blown out of the basin with a breath, and its place filled by a storm- wind from the north that sent the condor wheeling down the blast and made the coyote shiver on the hill. How was it possible that such a furnace could grow so cold! And once or more each winter, when the sky darkened with clouds, there was a fall of snow that for an hour or so whitened the desert mountains and then passed away. At those times the springs were frozen, the high sierras were snow-bound, and down in the desert it seemed as though a great frost-sheet had been let down from above. ‘The brown skins for all their deer-hide clothing were red with cold, and the breath blown from the pony’s nostrils was white as smoke. A waste of intense heat and cold, of drouth and cloud-bursts, of winds and lightning, of storm and death, what could make any race of hunters or band of red men care for it ? What was the attraction, wherein the fascination ? How often have we wondered why the sailor loves the sea, why the Bedouin loves the sand ! What is there but a strip of sky and another THE APPROACH 19 strip of sand or water ? But there is a sim- plicity about large masses — simplicity in breadth, space and distance—that is inviting and ennobling. And there is something very restful about the horizontal line. Things that lie flat are at peace and the mind grows peace- ful with them. Furthermore, the waste places of the earth, the barren deserts, the tracts for- saken of men and given over to loneliness, have a peculiar attraction of their own. The weird solitude, the great silence, the grim desolation, are the very things with which every desert wanderer eventually falls in love. You think that very strange perhaps? Well, the beauty of the ugly was sometime a paradox, but to-day people admit its truth; and the grandeur of the desolate is just as paradoxical, yet the desert gives it proof. But the sun-tanned people who lived on this mountain top never gave thought to masses, or horizontal lines, or paradoxes. They lived here, it may be from necessity at first, and then stayed on because they loved the open wind- blown country, the shining orange-hued sands, the sweeping mesas, the great swing of the horizontal circle, the flat desolation, the un- broken solitude. Nor ever knew why they Grim des- olation. Love for the desert, 20 THE DESERT The descent. The Padres. loved it. They were content and that was enough. What finally became of them? Who knows? One by one they passed away, or perhaps were all slaughtered in a night by the fierce band newly come to numbers called the Apaches. This stone wall stands as their monument, but it tells no date or tale of death. As I descend the trail of stone the fancy keeps harping on the countless times the bare feet must have rubbed those blocks of syenite and porphyry to wear them so smooth. Have there been no others to clamber up these stairs of stone ? What of the Padres—were they not here ? As I ride off across the plain to the east the thought is of the heroism, the self-abnega- tion, the undying faith of those followers of Loyola and Xavier who came into this waste so many years ago. How idle seem all the specious tales of Jesuitism and priestcraft. The Padres were men of soul, unshrinking faith, and a per- severance almost unparalleled in the annals of history. The accomplishments of Columbus, of Cortez, of Coronado were great; but what of those who first ventured out upon these sands and erected missions almost in the heart of the desert, who single-handed coped with dangers THE APPROACH 21 from man and nature, and who lived and died without the slightest hope of reward here on earth ? Has not the sign of the cross cast more men in heroic mould than ever the glitter of the crown or the flash of the sword ? And thinking such thoughts I turn to take a final view of the mountain ; and there on the fortified top something rears itself against the sky like the cross-hilt of a sword. It is the giant sahuaro with its rising arms, and beside it the cream-white bloom of the yucca shining in the sunlight seems like a lamp illuminating it. The good Padres have gone and their mis- sion churches are crumbling back to the earth from which they were made; but the light of the cross still shines along the borders of this desert land. The flame, that through them the Spirit kindled, still burns ; and in every Indian village, in every Mexican adobe, you will see on the wall the wooden or grass-woven cross. On the high hills and at the cross-roads it stands, roughly hewn from mesquite and planted in a cone of stones. It is now always weather-stained and sun-cracked, but still the sign before which the peon and the Indian bow the head and whis- per words of prayer. The dwellers beside the desert have cherished what the inhabitants of Light of the cross, Aboriginal Faith. 22 THE DESERT the fertile plains have thrown away. ‘They and their forefathers have never known civilization, and never suffered from the blight of doubt. Of a simple nature, they have lived in a simple way, close to their mother earth, beside the desert they loved, and (let us believe it !) nearer to the God they worshipped. CHAPTER II THE MAKE OF THE DESERT THE first going-down into the desert is always something of a surprise. The fancy has pictured one thing ; the reality shows quite another thing. Where and how did we gain the idea that the desert was merely a sea of sand ? Did it come from that geography of our youth with the illustration of the sand-storm, the flying camel, and the over-excited Bedouin ? Or have we been reading strange tales told by travellers of perfervid imagination—the Marco Polos of to-day ? There is, to be sure, some modicum of truth even in the statement that misleads. There are ‘‘ seas” or lakes or ponds of sand on every desert; but they are not so vast, not so oceanic, that you ever lose sight of the land. What land? Why, the mountains. The desert is traversed by many mountain ranges, some of them long, some short, some low, and some rising upward ten thousand feet. They 23 Sea of sand, Mountain ranges on the desert 24 THE DESERT Plains, val- leys, and mesas. Effect of drought. are always circling you with a ragged horizon, dark-hued, bare-faced, barren—just as truly desert as the sands which were washed down from them. Between the ranges there are wide-expanding plains or valleys. ‘The most arid portions of the desert le in the basins of these great valleys—flat spaces that were once the beds of lakes, but are now dried out and left perhaps with an alkaline deposit that pre- vents vegetation. Through these valleys run arroyos or dry stream-beds—shallow channels where gravel and rocks are rolled during cloud- bursts and where sands drift with every wind. At times the valleys are more diversified, that is, broken by benches of land called mesas, dotted with small groups of hills called lomas, crossed by long stratified faces of rock called escarp- ments. With these large features of landscape com- mon to all countries, how does the desert differ from any other land? Only in the matter of water—the lack of it. If Southern France should receive no more than two inches of rain a year for twenty years it would, at the end of that time, look very like the Sahara, and the flashing Rhone would resemble the sluggish yellow Nile. If the Adirondack region in New THE MAKE OF THE DESERT 25 York were comparatively rainless for the same length of time we should have something like the Mojave Desert, with the Hudson changed into the red Colorado. The conformations of the lands are not widely different, but their surface appearances are as unlike as it is pos- sible to imagine. For the whole face of a land is changed by the rains. With them come meadow-grasses and flowers, hillside vines and bushes, fields of yellow grain, orchards of pink-white blossoms. Along the mountain sides they grow the forests of blue-green pine, on the peaks they put white caps of snow; and in the valleys they gather their waste waters into shining rivers and flash- ing lakes. This is the very sheen and sparkle —the witchery—of landscape which lend allure- ment to such countries as New England, France, or Austria, and make them livable and lovable lands. But the desert has none of these charms. Nor is it a livable place. There is not a thing about it that is ‘‘ pretty,” and not a spot upon it that is “‘ picturesque” in any Berkshire-Val- ley sense. The shadows of foliage, the drift of clouds, the fall of rain upon leaves, the sound of running waters—all the gentler qualities of The effect of rains. Harshness of the desert. 26 THE DESERT gaunt na. Conditions of life. nature that minor poets love to juggle with— are missing on the desert. It is stern, harsh, and at first repellent. But what tongue shal] tell the majesty of it, the eternal strength of it, the poetry of its wide-spread chaos, the sub- limity of its lonely desolation! And who shall paint the splendor of its light; and from the rising up of the sun to the going down of the moon over the iron mountains, the glory of its wondrous coloring! It is a gaunt land of splintered peaks, torn valleys, and hot skies. And at every step there is the suggestion of the fierce, the defiant, the defensive. Everything within its borders seems fighting to maintain itself against destroying forces. There is a war of elements and a struggle for existence going on here that for ferocity is unparalleled else- where in nature. The feeling of fierceness grows upon you as you come to know the desert better. ‘The sun- shafts are falling in a burning shower upon rock and dune, the winds blowing with the breath of far-off fires are withering the bushes and the grasses, the sands drifting higher and higher are burying the trees and reaching up as though they would overwhelm the mountains, the cloud-bursts are rushing down the moun- THE MAKE OF THE DESERT tain’s side and through the torn arroyos as though they would wash the earth into the sea. The life, too, on the desert is peculiarly savage. It is a show of teeth in bush and beast and reptile. At every turn one feels the presence of the barb and thorn, the jaw and paw, the beak and talon, the sting and the poison thereof. Even the harmless Gila monster flattens his body on a rock and hisses a “‘ Don’t step on me.” There is no living in concord or brother- hood here. Everything is at war with its neighbor, and the conflict is unceasing. Yet this conflict is not so obvious on the face of things. You hear no clash or crash or snarl. The desert is overwhelmingly silent. There is not a sound to be heard; and nota thing moves save the wind and the sands. But you look up at the worn peaks and the jagged bar- rancas, you look down at the wash-outs and piled bowlders, you look about at the wind- tossed, half-starved bushes; and, for all the silence, you know that there is a struggle for life, a war for place, going on day by day. How is it possible under such conditions for much vegetation to flourish ? The grasses are scanty, the grease-wood and cactus grow in patches, the mesquite crops out only along the Elemental warfare. Desert vegetation. 28 THE DESERT Protruding edges. Shifting sands. dry river-beds. All told there is hardly enough covering to hide the anatomy of the earth. And the winds are always blowing it aside. You have noticed how bare and bony the hills of New England are in winter when the trees are leafless and the grasses are dead ? You have seen the rocks loom up harsh and sharp, the ledges assume angles, and the backbone and ribs of the open field crop out of the soil? The desert is not unlike that all the year round. To be sure there are snow-like driftings of sand that muffle certain edges. Valleys, hills, and even mountains are turned into rounded lines by it at times. But the drift rolled high in one place was cut out from some other place ; and always there are vertebre showing—elbows and shoulders protruding through the yellow byssus of sand. The shifting sands! Slowly they move, wave upon wave, drift upon drift; but by day and by night they gather, gather, gather. They overwhelm, they bury, they destroy, and then a spirit of restlessness seizes them and they move off elsewhere, swirl upon swirl, line upon line, in serpentine windings that enfold some new growth or fill in some new valley in the waste. So it happens that the surface of the THE MAKE OF THE DESERT 29 desert is far from being a permanent affair. There is hardly enough vegetation to hold the sands in place. With little or no restraint upon them they are transported hither and yon at the mercy of the winds. Yet the desert winds hardly blow where they list. They follow certain channels or ‘‘ draws” through the mountain ranges ; and the reason for their doing so is plain enough. During the day the intense heat of the desert, meeting with only a thin dry air above it, rises rapidly sky- ward leaving a vast vacuum below that must be filled with a colder air from without. This colder air on the southern portion of the Colo- rado Desert comes in from the Gulf region. One can feel it in the passes of the mountains about Baboquivari, rushing up toward the heated portions of Arizona around Tucson. And the hotter the day the stronger the inward rush of the wind. Some days it will blow at the rate of fifty miles an hour until sunset, and then with a cessation of radiation the wind stops and the night is still. On the western portions of the Colorado the wind comes from the Pacific across Southern California. The hot air from the desert goes up and out over the Coast Range, reaching sea- Desert winds, Radiation of heat. 30 THE DESERT Prevailing winds. Wear of the winds. ward. How far out it goes is unknown, but when it has cooled off it descends and flows back toward the land as the daily sea-breeze. It re-enters the desert through such loop holes in the Coast Range as the San Gorgonio Pass— the old Puerta de San Carlos—above Indio. The rush of it through that pass is quite vio- lent at times. For wind is very much like water and seeks the least obstructed way. Its goal is usually the hottest and the lowest place on the desert—such a place, for example, as Salton, though I am not prepared to point out the exact spot on the desert that the winds choose as a target. On the Mojave Desert at the north their action is similar, though there they draw down from the Mount Whitney re- gion as well as from the Pacific. In open places these desert winds are some- times terrific in force though usually they are moderate and blow with steadiness from certain directions. As you feel them softly blowing against your cheek it is hard to imagine that they have any sharp edge to them. Yet about you on every side is abundant evidence of their works. The sculptor’s sand-blast works swifter but not surer. Granite and porphyry cannot withstand them, and in time they even cut THE MAKE OF THE DESERT 31 through the glassy surface of lava. Their wear is not here nor there, but all over, everywhere. The edge of the wind is always against the stone. Continually there is the slow erosion of canyon, crag, and peak ; forever there is a gnawing at the bases and along the face-walls of the great sierras. Grain by grain, the vast foundations, the beetling escarpments, the high domes in air are crumbled away and drifted into the valleys. Nature heaved up these mountains at one time to fulfil a purpose: she is now taking them down to fulfil another purpose. If she has not water to work with here as elsewhere she is not baffled of her purpose. Wind and sand an- swer quite as well. But the cutting of the wind is not always even or uniform, owing to the inequalities in the fibre of rock ; and often odd effects are pro- duced by the softer pieces of rock wearing away first and leaving the harder section exposed to view. Frequently these remainders take on fantastic shapes and are likened to things hnu- man, such as faces, heads, and hands. In the San Gorgonio Pass the rock-cuttings are in parallel lines, and occasionally a row of gar- nets in the rock will make the jewel-pointed fingers of a hand protruding from the parent Erosion of mountains.

Perhaps the greatest erosion is in the passes through which the winds rush into the desert. Here they not only eat into the ledges and cut away the rock faces, but they make great wash- outs in the desert itself. These trenches look in every respect as though caused by water. In fact the effects of wind and water are often so inextricably mixed that not even an expert geol- ogist would be able to say where the one leaves off and the other begins. The shallow caves of the mountains—too high up for any wave action from sea or lake, and too deep to be reached by rains—have all the rounded appearance of water-worn receptacles. One can almost see the water-lines upon the walls. But the sand- heaped floor suggests that the agent of erosion was the wind.

Even Sahara gets its occa- sional showers, and the Colorado and the Mo- jave show many traces of the cloud-burst. The dark thunder-clouds that occasionally gather over the desert seem at times to reserve all their stores of rain for one place. The fall is usually short-lived but violent; and its greatest force is always on the mountains. There is no sod, no moss, to check or retard the flood ; and the result is a great rush of water to the low places. In the canyons the swollen streams roll down bowlders that weigh tons, and in the ravines many a huge barranca is formed in a single hour by these rushing waters. On the lomas and sloping valleys they are not less destructive, running in swift streams down the hollows, and whirling stones, sand, and torn bushes into the old river-beds. In a very short time there is a great torrent pouring down the valley—a torrent composed of water, sand, and gravel in about equal parts. It is a yellow, thick stream that has nothing but disaster for the man or beast that seeks to swim it. Many a life has been lost there. The great onset of the water destroys anything like buoy- ancy, and the tendency is to drag down and roll the swimmer like a bowlder. Even the Canyon streams. Desert Jloods, 34 THE DESERT Power of water. Water- pockets. No running streams. enormous strength of the grizzly bear has been known to fail him in these desert rivers. They boil and seethe as though they were hot; and they rush on against banks, ripping out the long roots of mesquite, and swirling away tons of undermined gravel as though it were only so much snow. At last after miles of this mill- racing the force begins to diminish, the streams reach the flat lake-beds and spread into broad, thin sheets; and soon they have totally van- ished, leaving scarcely a rack behind. The desert rainfall comes quickly and goes quickly. ‘The sands drink it up, and it sinks to the rock strata, where, following the ledges, it is finally shelved into some gravel-bed. There, perhaps a hundred feet under the sand, it slow- ly oozes away to the river or the Gulf. There is none of it remains upon the surface except perhaps a pool caught in a clay basin, or a catch of water in a rocky bowl of some canyon. Occasionally one meets with a little stream where a fissure in the rock and a pressure from below forces up some of the water; but these springs are of very rare occurrence. And they always seem a little strange. A brook that ran on the top of the ground would be an anomaly here ; and after one lives many months on the THE MAKE OF THE DESERT 35 desert and returns to a well-watered country, the last thing he becomes accustomed to is the sight of running water. In every desert there are isolated places where water stands in pools, fed by under- ground springs, where mesquite and palms grow, and where there is a show of coarse grass over some acres. These are the so-called oases in the waste that travellers have pictured as Gardens of Paradise, and poets have used for centuries as illustrations of happiness sur- rounded by despair. ‘To tell the truth they are wretched little mud-holes ; and yet because of their few trees and their pockets of yellow brackish water they have an appearance of un- reality. They are strange because bright-green foliage and moisture of any kind seem out of place on the desert. | | Yet surely there was plenty of water here at one time. Everywhere you meet with the dry lake-bed—its flat surface devoid of life and of- ten glimmering white with salt. These beds are no doubt of recent origin geologically, and were never more than the catch-basins of sur- face water; but long before ever they were brought forth the whole area of the desert was under the sea. ‘To-day one may find on Oases in the waste. Oatch- basins. 36 THE DESERT Old sea- beds. Volcanic action. Lava streams. the high table-lands sea-shells in abundance. The petrified clams are precisely like the live clams that one picks up on the western coast of Mexico. The corals, barnacles, dried sponge forms, and cellular rocks do not differ from those in the Gulf of California. The change from sea to shore, and from shore to table-land and mountain, no doubt took place very slow- ly. Just how many centuries ago who shall say ? Geologists may guess and laymen may doubt, but the Keeper of the Seals says noth- ing. Nor is it known just when the porphyry mountains were roasted to a dark wine-red, and the foot-hills burnt to a terra-cotta orange. Fire has been at work here as well as wind and water. The whole country has a burnt and scorched look proceeding from something more fiery than sunlight. Volcanoes have left their traces everywhere. Yon can still see the streams of lava that have chilled as they ran. The blackened cones with their craters exist ; and about them, for many miles, there are great lakes and streams of reddish-black lava, frozen in swirls and pools, cracked like glass, broken into blocks like a ruined pavement. Wherever you go on the desert you meet with THE MAKE OF THE DESERT 37 chips and breaks of lava, showing that at one time there must have been quantities of it belched out of the volcanoes. There were convulsions in those days when the sea washed close to the bases of the moun- tains. Through the crevasses and fissures in the rocks the water crept into the fires of the earth, and explosions—volcanic eruptions—were the result. Wandering over these stony tracks you might fancy that all strata and all geological ages were blown into discord by those explo- sions. For here are many kinds of splintered and twisted rocks—rocks aqueous and igne- ous, gritstones, conglomerates, shales, slates, syenite, basalt. And everywhere the white coatings of carbonate of lime that look as though they were run hot from a puddling fur- nace; and the dust of sulphur, copper, and iron blown upon granite as though oxidized by fire. The evidence for glaciers is not so convinc- ing. There is no apparent sign of an ice age. Occasionally one sees scratches upon mountain walls that are suspicious, or heaps of sand and gravel that look as though pushed into the small valleys by some huge force. And again there are places on the Mojave where windrows Geological ages. Kinds of rock. Glaciers. 38 THE DESERT Land slips. Movement of stones. The talus. of heavy bowlders are piled on either side of mountain water-courses, looking as though ice may have caused their peculiar placing. But there is no certainty about any of these. Land slips may have made the windrows as easily as ice slips ; and water can heap mounds of sand and gravel as readily as glaciers. One cannot trace the geological ages with such facility. Things sometimes ‘‘just happen,” in spite of scientific theories. Besides, the movement of the stones into the valleys is going on continuously, irrespective of glaciers. They are first broken from the peaks by erosion, and then they fall into what is called a talus—a great slope of stone blocks beginning half way down the mountain and often reaching to the base or foot. Many of them, of course, are rolled over steep declivities into the canyons and thence carried down by flood waters; but the talus is the more uniform method for bowl- ders reaching the plain. In the first stage of the talus the blocks are ragged-edged and as largeasa barrel. Nothing whatever grows upon theslope. It is as bare as the side of a volcanic crater. And just as diffi- cult to walk over. The talus is added to at the top by the falling rock of the face-wall, and it THE MAKE OF THE DESERT 39 is losing at the bottom by the under blocks grinding away to stone and gravel. The flat- tening out at the bottom, the breaking up of the blocks, and the push-out of the mountain foot upon the plain is the second stage of the talus. In almost all the large valleys of the desert the depressed talus extends, sometimes miles in length, out from the foot of the moun- tain range. When it finally slips down into the valley and becomes a flat floor it has entered upon its third and last stage. It is then the ordinary valley-bed covered with its cactus and cut by itsarroyos. Yet this valley-floor instead of being just one thing is really many things— or rather made up of many different materials and showing many different surfaces. You may spend days and weeks studying the make-up of these desert-floors. Beyond Yuma on the Colorado there are thousands of acres of mosaic pavement, made from tiny blocks of jasper, carnelian, agate—a pavement of pebbles so hard that a horse’s hoof will make no im- pression upon it—wind-swept, clean, compact as though pressed down by a roller. One can imagine it made by the winds that have cut and drifted away the light sands and allowed the pebbles to settle close together until they Stages of the talus.

For no known reason other portions of the desert are covered with blocks of red-incrusted sandstone —the incrustation being only above the sand- line. In the lake-beds there is usually a surface of fine silt. It is not a hard surface though it often has a crust uponit that a wild cat can walk upon, but a horse or a man would pound through as easily as through crusted snow. The salt-beds are of sporadic appearance and hardly count as normal features of the desert. They are often quite’ beautiful in appearance. The one on the Colorado near Salton is hard as ice, white, and after sunset it often turns blue, yellow, or crimson, dependent upon the sky overhead which it reflects. Borax and gypsum- beds are even scarcer than the salt-beds. They are also white and often very brilliant reflectors of the sky. The sand-beds are, of course, more frequently met with than any others; and yet your horse does not go knee-deep in sand for any great distance. It is too light, and is drifted too easily by the winds. Bowlders, gravel, and general mountain wash is the most common flooring of all. The mountains whence all the wash comes, are mere ranges of rock. In the canyons, where THE MAKE OF THE DESERT 41 there is perhaps some underground water, there are occasionally found trees and large bushes, and the very high sierras have forests of pine belted about their tops; but usually the desert ranges are barren. ‘'hey never bore fruit. The washings from them are grit and fry of rock but no vegetable mould. The black dirt that lies a foot or more in depth upon the surface of the eastern prairies, showing the many years accumulations of decayed grasses and weeds, is not known anywhere on the desert. The slight vegetation that grows never hasa chance to turn into mould. And besides, nothing ever rots or decays in these sands. Iron will not rust, nor tin tarnish, nor flesh mortify. The grass and the shrub wither and are finally cut into pieces by flying sands. Sometimes you may see small particles of grass or twigs heaped about an ant- hill, or find them a part of a bird’s nest in a cholla; but usually they turn to dry dust and blow with the wind—at the wind’s will. The desert mountains gathered in clusters along the waste, how old and wrinkled, how set and determined they look! Somehow they remind you of a clenched hand with the knuckles turned skyward. They have strength and bulk, the suggestion of quiescent force. Mountain vegetation. Withered. grasses. 42 THE DESERT Barren rock. Mountain colors. Saw-toothed rtdges. Barren rock and nothing more ; but what could better epitomize power! The heave of the enormous ridge, the loom of the domed top, the bulk and body of the whole are colossal. Rising as they do from flat sands they give the impression of things deep-based—veritable isl- ands of porphyry bent upward from a yellow sea. They are so weather-stained, so worn, that they are not bright in coloring. Usually they assume a dull garnet-red, or the red of peroxide of iron; but occasionally at sunset they warm in color and look fire-red through the pink haze. The more abrupt ranges that appear younger because of their saw-toothed ridges and broken peaks, are often much finer in coloring. They have needles that are lifted skyward like Mos- lem minarets or cathedral spires ; and at even- ing, if there is a yellow light, they shine like brazen spear-points set against the sky. It is astonishing that dull rock can disclose such marvellous coloring. The coloring is not local in the rock, nor yet again entirely reflected. Desert atmosphere, with which we shall have to reckon hereafter, has much to do with it. And whether at sunset, at sunrise, or at mid- \night, how like watch-towers these mountains THE MAKE OF THE DESERT 43 stand above the waste! One can almost fancy that behind each dome and rampart there are cloud-like Genii—spirits of the desert—keeping guard over this kingdom of the sun. And what a far-reaching kingdom they watch! Plain upon plain leads up and out to the horizon—far as the eye can see—in undulations of gray and gold ; ridge upon ridge melts into the blue of the distant sky in lines of lilac and purple ; fold upon fold over the mesas the hot air drops its veilings of opal and topaz. Yes; it is the kingdom of sun-fire. For every color in the scale is attuned to the key of flame, every air- wave comes with the breath of flame, every sunbeam falls as a shaft of flame. There is no questioning who is sovereign in these do- minions. Seen from the peaks. Sun-fire kingdom. Early geological days. The former Gulf. CHAPTER III THE BOTTOM OF THE BOWL In the ancient days when the shore of the Pacific was young, when the white sierras had only recently been heaved upward and the des- ert itself was in a formative stage, the ocean reached much farther inland than at the pres- ent time. It pushed through many a pass and flooded many a depression in the sands, as its wave-marks upon granite bases and its numer- ous beaches still bear witness. In those days that portion of the Colorado Desert known as the Salton Basin did not exist. The Gulf of California extended as far north as the San Bernardino Range and as far west as the Pass of San Gorgonio. Its waters stood deep where now lies the road-bed of the Southern Pacific railway, and all the country from Indio almost to the Colorado River was a blue sea. The Bowl was full. No one knew if it had a bot- tom or imagined that it would ever be emptied of water and given over to the drifting sands. 44 THE BOTTOM OF THE BOWL 45 No doubt the tenure of the sea in this Salton Basin was of long duration. The sand-dunes still standing along the northern shore—fifty feet high and shining like hills of chalk— were not made in a month; nor was the long shelving beach beneath them — still covered with sea-shells and pebbles and looking as though washed by the waves only yesterday— formed in a day. Both dunes and beach are plainly visible winding across the desert for many miles. The southwestern shore, stretch- ing under a spur of the Coast Range, shows the same formation in its beach-line. The old bays and lagoons that led inland from the sea, the river-beds that brought down the surface waters from the mountains, the inlets and nat- ural harbors are all in place. Some of them are drifted half full of sand, but they have not lost their identity. And out in the sea-bed still stand masses of cellular rock, honeycombed and water-worn (and now for many years wind- worn), showing the places where once rose the reefs of the ancient sea. These are the only records that tell of the sea’s occupation. The Indians have no tra- dition about it. Yet when the sea was there the Indian tribes were there also. Along the Sea-beaches on desert. Harbors and reefs 46 THE DESERT Indian remains. The Cocopas. The Oolorado River. bases of the San Bernardino and San Jacinto Ranges there are indications of cave-dwelling, rock-built squares that doubtless were fortified camps, heaps of stone that might have been burial-mounds. Everywhere along the ancient shores and beaches you pick up pieces of pot- tery, broken ollas, stone pestels and mortars, axe - heads, obsidian arrow - heads, flint spear- points, agate beads. There is not the slightest doubt that the shores were inhabited. It was a warm nook, accessible to the mountains and the Pacific; in fact, just the place where tribes would naturally gather. Branches of the Yuma Indians, like the Cocopas, overran all this country when the Padres first crossed the desert; and it was probably their fore- fathers who lived by the shores of this Upper Gulf. No doubt they were fishermen, traders and fighters, like their modern representatives on Tiburon Island ; and no doubt they fished and fought and were happy by the shores of the mountain-locked sea. But there came a time when there was a dis- turbance of the existing conditions in the Up- per Gulf. Century after century the Colorado River had been carrying down to the sea its - burden of sedimental sand and silt. It had THE BOTTOM OF THE BOWL 47 been entering the Gulf far down on the eastern side at an acute angle. Gradually its deposits had been building up, banking up; and grad- ually the river had been pushing them out and across the Gulf in a southwesterly direction. Finally there was formed a delta dam stretch- ing from shore to shore. ‘The tides no longer brought water up and around the bases of the big mountains; Communication with the sea was cut off and what was once the top of the Gulf changed into an inland lake. It now had no water supply from below, it lay under a burning sun, and day by day evaporation car- ried it away. No one knows how many days, how many years, elapsed before the decrease of the water became noticeable. Doubtless the lake shrunk away slowly from the white face of the sand- dunes and the red walls of the mountains. The river-mouths that opened into the lake narrowed themselves to small stream - beds. The shelving beaches where the waves had fallen lazily year after year, pushing themselves over the sand in beautiful water-mirrors, shone bare and dry in the sunlight. The ragged reefs, over which the chop sea had tumbled and tossed so long, lifted their black hulks out The delta dam. The inland lake. 48 THE DESERT The first fall. Springs and wells in the sea-bed. The New River. of the water and with their hosts of barnacles and sea-life became a part of the land. The waters of the great inland lake fell per- haps a hundred feet and then they made a pause. The exposed shores dried out. They baked hard in the sun, and were slowly ground down to sand and powdered silt by the action of the winds. The waters made a long pause. They were re- ceiving reinforcements from some source. Pos- sibly there was more rainfall in those days than now, and the streams entering the lake from the mountains were much larger. Again there may have been underground springs. There are flowing wells to-day in this old sea-bed— wells that cast up water salter than the sea it- self. No one knows their fountain-head. Per- haps by underground channels the water creeps through from the Gulf, or comes from mountain reservoirs and turns saline by passing through beds of salt. These are the might-bes ; but it is far more probable that the Colorado River at high water had made a breach of some kind in the dam of its own construction and had poured overflow water into the lake by way of a dry channel called the New River. The bed of this river runs northward from below the boundary- line of Lower California ; and in 1893, during THE BOTTOM OF THE BOWL 49 a rise in the Colorado, the waters rushed in and flooded the whole of what is called the Salton Basin. When the Colorado receded, the basin soon dried out again. It was undoubtedly some accident of this kind that called the halt in the original reces- sion. During the interim the lake had time to form new shores where the waves pounded and washed on the gravel as before until miles upon miles of new beach—pebbled, shelled, and slop- ing downward with great uniformity—came into existence. This secondary beach is intact to- day and looks precisely like the primary except that it is not quite so large. Across the basin, along the southern mountains, the second water- tracery is almost as apparent as the first. The rocks are eaten in long lines by wave-action, and are honeycombed by the ceaseless energies of the zodphite. Nor was the change in beach and rock alone. New bays and harbors were cut out from where the sea had been, new river-channels were opened down to the shrunken lake, new lagoons were spread over the flat places. Nature evi- dently made a great effort to repair the damage and adapt the lake to its new conditions. And the Indians, too, accepted the change. There New beaches.

The failing water. are many indications in broken pottery, arrow- heads, and mortars that the aboriginal tribes moved down to the new beach and built wick- iups by the diminished waters. And the old fishing-foraging-fighting life was probably re- sumed. Then once more the waters went down, down, down. Step by step they receded until the sec- ondary beach was left a hundred feet above the water level. Again there was a pause. Again new beaches were beaten into shape by the waves, new bays were opened, new arroyos cut through from above. ‘The whole process of shore-making—the fitting of the land to the shrunken proportions of the lake—was gone through with for the third time; while the water supply from the river or elsewhere was maintained in decreased volume but with some steadiness of flow. Possibly the third halt of the receding water was not for a great length of time. The tertiary beach is not so large as its predecessors. There never was any strong wave- action upon it, its pebbles are few, its faults and breaks are many. The water supply was failing, and finally it ceased altogether. What fate for a lake in the desert receiving no supplies from river or sea—what fate save THE BOTTOM OF THE BOWL 51 annihilation ? The hot breath of the wind blew across the cramped water and whipped its sur- face into little waves; and as each tiny point of spray rose on the crest and was lifted into the air the fiery sunbeam caught it, and in a twinkling had evaporated and carried it up- ward. Day by day this process went on over the whole surface until there was no more sea. The hollow reefs rose high and dark above the bed, the flat shoals of silt lifted out of the ooze, and down in the lowest pools there was the rush and plunge of monster tortuabas, sharks and porpoises, caught as it were in a net and vainly struggling to getout. How strange must have seemed that landscape when the low ridges were shining with the slime of the sea, when the beds were strewn with alge, sponges, and coral, and the shores were whitening with salt ! How strange, indeed, must have been the first sight of the Bottom of the Bowl! But the sun never relaxed its fierce heat nor the wind its hot breath. They scorched and burned the silt of the sea-bed until it baked and cracked into blocks. Then began the wear |» of the winds upon the broken edges until the blocks were reduced to dry fine powder, FKi- nally the desert came in. Drifts upon drifts of Evapo- ration. Bottom of the Bowl.

Desolation of the basin. sand blown through the valleys settled in the empty basin; gravel and bowlder-wash came down from the mountains ; the grease-wood, the salt-bush, and the so-called pepper-grass sprang up in isolated spots. Slowly the desert fastened itself upon the basin. Its heat became too intense to allow the falling rain to reach the earth, its surface was too salt and alkaline to allow of much vegetation, it could support neither animal nor bird life; it became more deserted than the desert itself. And thus it remains to this day. When yon are in the bottom of it you are nearly three hundred feet below the level of the sea. Cir- cling about you to the north, south, and west are sierras, some of them over ten thousand feet in height. These form the Rim of the Bowl. And off to the southwest there is a side broken out of the Bowl through which you can pass to the river and the Gulf. The basin is perhaps the hottest place to be found anywhere on the American deserts. And it is also the most for- saken. 'The bottom itself is, for the great part of it, as flat as a table. It looks like a great plain leading up and out to the horizon—a plain that has been ploughed and rolled smooth. The soil is drifted silt—the deposits made by THE BOTTOM OF THE BOWL 53 the washings from the mountains—and is almost as fine as flour. The long line of dunes at the north are just as desolate, yet they are wonderfully beautiful. The desert sand is finer than snow, and its curves and arches, as it builds its succession of drifts out and over an arroyo, are as graceful as the lines of running water. The dunes are al- ways rhythmical and flowing in their forms ; and for color the desert has nothing that sur- passes them. In the early morning, before the sun is up, they are air-blue, reflecting the sky overhead ; at noon they are pale lines of daz- zling orange-colored light, waving and undulat- ing in the heated air ; at sunset they are often flooded with a rose or mauve color; undera blue moonlight they shine white as icebergs in the northern seas. But neither the dunes nor the flats grow vegetation of consequence. About the high edges, up near the mountain slopes, you find growths of mesquite, palo verde, and cactus ; but down in the basin there are many miles where no weed or grass breaks the level uni- formity. Not even the salt-bush will grow in some of the areas. And this is not due to poverty of soil but to absence of water and Beauty of the sand- dunes. Oactus and salt-bush. ia) | nS THE DESERT Desert . animals in the basin. Birds. Lizards and snakes. intense heat. Plants cannot live by sunlight alone. Nor will the desert animals inhabit an abso- lute waste. The coyote and the wild cat do not relish life in this dip in the earth. They care little for heat and drouth, but the question of food appeals to them. There is nothing to eat. Even the abstemious jack-rabbit finds living here something of a difficulty. Many kinds of tracks are found in the uncrusted silt—tracks of coyotes, gray wolves, sometimes mountain lions—but they all run in straight trails, show- ing the animals to be crossing the basin to the mountains, not prowling or hunting. So, too, you will occasionally find birds—linnets, bobo- links, mocking-birds, larks—but they are seen one at a time, and they look weary like land birds far out at sea that seek a resting-place on passing vessels. They do not belong to the desert and are only stopping there temporarily on some long flight. Snakes and lizards are not particular about their abiding-place, and yet they do not care to live in a land where there is no bush or stone to creep under. You meet with them very seldom. Practically there is no life of any kind that is native to the place. Is there any beauty, other than the dunes, awit mag THE BOTTOM OF THE BOWL 55 down in this hollow of the desert? Yes. From a picturesque point of view it has the most wonderful light, air, and color imaginable. You will not think so until you see them blended in that strange illusion known as mirage. And here is the one place in all the world where the water-mirage appears to per- fection. It does not show well over grassy or bushy ground, but over the flat lake-beds of the desert its appearance is astonishing. Down in the basin it is accompanied by a second illusion that makes the first more convincing. You are below sea-level, but instead of the ground about you sloping up and ont, it apparently slopes down and away on every side. You are in the centre of a disk or high point of ground, and around the circumference of the disk is water—palpable, almost tangible, water. It cannot be seen well from your horse, and fifty feet up on a mountain side it would not be visible at all. But dismount and you see it better ; kneel down and place your cheek to the ground and now the water seems to creep up to you. You could throw a stone into it. The shore where the waves lap is just before you. But where is the horizon-line ? Odd enough, this vast circling sea does not always know a Mirage. The water illusion. 56 THE DESERT Decorative landscapes. Sensuous qualities in nacure. horizon ; it sometimes reaches up and blends into the sky without any point of demarcation. Through the heated air you see faint outlines of mountains, dim glimpses of foot-hills, sugges- tions of distance; but no more. Across them is drawn the wavering veil of air, and the red earth at your feet, the blue sky overhead, are but bordering bands of flat color. And there you have the most decorative land- scape in the world, a landscape all color, a dream landscape. Painters for years have been trying to put it upon canvas—this landscape of color, light, and air, with form almost obliterated, merely suggested, given only as a hint of the mysterious. Men like Corot and Monet have told us, again and again, that in painting, clearly delineated forms of mountains, valleys, trees, and rivers, kill the fine color-sentiment of the picture. The great struggle of the modern landscapist is to get on with the least possible form and to suggest everything by tones of color, shades of light, drifts of air. Why? Because these are the most sensuous qualities in nature and in art. The landscape that is the simplest in form and the finest in color is by all odds the most beautiful. It is owing to just these feat- ures that this Bowl of the desert is a thing of THE BOTTOM OF THE BOWL 57 beauty instead of a dreary hollow in the hills. Only one other scene is comparable to it, and that the southern seas at sunset when the calm ocean reflects and melts into the color-glory of the sky. It is the same kind of beauty. Form is almost blurred out in favor of color and air. Yet here is more beauty destined to destruc- tion. It might be thought that this forsaken pot-hole in the ground would never come under the dominion of man, that its very worthlessness would be its safeguard against civilization, that none would want it, and everyone from necessity would let it alone. But not even the spot de- serted by reptiles shall escape the industry or the avarice (as you please) of man. A great company has been formed to turn the Colorado River into the sands, to reclaim this desert basin, and make it blossom as the rose. The water is to be brought down to the basin by the old channel of the New River. Once in reservoirs it is to be distributed over the tract by irrigating ditches, and it is said a million acres of desert will thus be made arable, fitted for homesteads, ready for the settler who never remains settled. A most laudable enterprise, people will say. Yes; commercially no one can find fault with it Money made from sand is likely to be clean Changing the desert. Trrigation in the basin 58 THE DESERT Changing the climate. Dry air. money, at any rate. And economically these acres will produce large supplies of food. That is commendable, too, even if those for whom it is produced waste a good half of what they already possess. And yet the food that is pro- duced there may prove expensive to people other than the producers. ‘This old sea-bed is, for its area, probably the greatest dry-heat generator in the world because of its depression and its barren, sandy surface. It is a furnace that whirls heat up and out of the Bowl, over the peaks of the Coast Range into Southern California, and eastward across the plains to Arizona and Sonora. In what measure it is re- sponsible for the general climate of those States cannot be accurately summarized ; but it cer- tainly has a great influence, especially in the matter of producing dry air. To turn this desert into an agricultural tract would be to increase humidity, and that would be practi- cally to nullify the finest air on the continent. And why are not good air and climate as es- sential to human well-being as good beef and good bread ? Just now, when it is a world too late, our Government and the forestry societies of the country are awakening to the necessity of preserving the forests. National parks are THE BOTTOM OF THE BOWL 59 being created wherever possible and the cutting of timber within them is prohibited. Why is this being done? Ostensibly to preserve the trees, but in reality to preserve the water sup- ply, to keep the fountain-heads pure, to main- tain a uniform stage of water in the rivers. Very proper and right. The only pity is that it was not undertaken forty years ago. But how is the water supply, from an economic and hygienic stand-point, any more important than the air.supply ? Grasses, trees, shrubs, growing grain, they, too, may need good air as well as human lungs. The deserts are not worthless wastes. You cannot crop all creation with wheat and alfal- fa. Some sections must lie fallow that other sections may produce. Who shall say that the preternatural productiveness of California is not due to the warm air of its surrounding des- erts? Does anyone doubt that the healthful- ness of the countries lying west of the Mississ- ippi may be traced directly to the dry air and heat of the deserts. They furnish health to the human ; why not strength to the plant ? The deserts should never be reclaimed. They are the breathing-spaces of the west and should be preserved forever. Value of the air supply. Value of the deserts. 60 THE DESERT Destruction of natural beauty. Effects of MNING, lumbering, agriculture. To speak about sparing anything because it is beautiful is to waste one’s breath and incur ridicule in the bargain. The esthetic sense— the power to enjoy through the eye, the ear, and the imagination—is just as important a factor in the scheme of human happiness as the corporeal sense of eating and drinking ; but there has never been a time when the world would admit it. The ‘practical men,” who seem forever on the throne, know very well that beauty is only meant for lovers and young persons— stuff to suckle fools withal. The main affair of life is to get the dollar, and if there is any money in cutting the throat of Beauty, why, by all means, cut her throat. That is what the ‘‘ practical men” have been doing ever since the world began. It is not necessary to dig up ancient history ; for have we not seen, here in California and Oregon, in our own time, the destruction of the fairest valleys the sun ever shone upon by placer and hy- draulic mining ? Have we not seen in Minne- sota and Wisconsin the mightiest forests that ever raised head to the sky slashed to pieces by the axe and turned into a waste of tree- stumps and fallen timber ? Have we not seen the Upper Mississippi, by the destruction of THE BOTTOM OF THE BOWL 61 the forests, changed from a broad, majestic river into a shallow, muddy stream; and the beautiful prairies of Dakota turned under by the plough and then allowed to run to weeds ? Men must have coal though they ruin the val- leys and blacken the streams of Pennsylvania, they must have oil though they disfigure half of Ohio and Indiana, they must have copper if they wreck all the mountains of Montana and Arizona, and they must have gold though they blow Alaska into the Behring Sea. It is more than possible that the ‘‘ practical men” have gained much practice and many dol- lars by flaying the fair face of these United States. They have stripped the land of its robes of beauty, and what have they given in its place? Weeds, wire fences, oil-derricks, board shanties and board towns—things that not even a “practical man” can do less than curse at. And at last they have turned to the desert ! It remains to be seen what they will do with it. Reclaiming a waste may not be so easy as break- ing a prairie or cutting down a forest. And Nature will not always be driven from her purpose. Wind, sand, and heat on Sahara have proven hard forces to fight against ; they Ploughing the prairies ** Practical men”? Fighting wind, sand, and heat. 62 THE DESERT Nature aternal. Return of desolation. may prove no less potent on the Colorado. And sooner or later Nature will surely come to her own again. Nothing human is of long du- ration. Men and their deeds are obliterated, the race itself fades; but Nature goes calmly on with her projects. She works not for man’s enjoyment, but for her own satisfaction and her own glory. She made the fat lands of the earth with all their fruits and flowers and fo- liage ; and with no less care she made the des- ert with its sands and cacti. She intended that each should remain as she made it. When the locust swarm has passed, the flowers and grasses will return to the valley; when man is gone, the sand and the heat will come back to the desert. The desolation of the kingdom will live again, and down in the Bottom of the Bowl the opalescent mirage will waver skyward on wings of light, serene in its sol- itude, though no human eye sees nor human tongue speaks its loveliness. Fee ee CHAPTER IV THE SILENT RIVER THE career of the Colorado, from its rise in the Wind River Mountains in Wyoming to its final disappearance in the Gulf of California, seems almost tragic in its swift transitions. It starts out so cheerily upon its course ; it is so clear and pure, so sparkling with sunshine and spirit. It dashes down mountain valleys, gur- gles under bowlders, swirls over waterfalls, flashes through ravines and gorges. With its sweep and glide and its silvery laugh it seems to lead a merry life. But too soon it plunges into precipitous canyons and enters upon its fierce struggle with the encompassing rock. Now it boils and foams, leaps and strikes, thunders and shatters. For hundreds of miles it wears and worries and undermines the rock to its destruc- tion. During the long centuries it has cut down into the crust of the earth five thousand feet. But ever the stout walls keep casting it back, keep churning it into bubbles, beating it 63 Rise of the Colorado. In the canyon. 64 THE DESERT On the desert. The lower river. into froth. At last, its canyon course run, ex- hausted and helpless, it is pushed through the escarpments, thrust out upon the desert, to find its way to the sea as best it can. Its spirit is broken, its vivacity is extinguished, its color is deepened to a dark red—the trail of blood that leads up to the death. Wearily now it drifts across the desert without a ripple, without a moan. Likea wounded snake it drags its length far down the long wastes of sand to where the blue waves are flashing on the Californian Gulf. And there it meets—obliteration. After the clash and roar of the conflict in the canyons how impressive seems the stillness of the desert, how appalling the unbroken silence of the lower river! Day after day it moves sea- ward, but without a sound. You start at its banks to find no waves, no wash upon gravel beaches, no rush of water over shoals. Instead of the soothing murmur of breaking falls there is at times the boil of currents from below— waters flung up sullenly and soon flattened into drifting nothingness by their own weight. And how heavily the stream moves! _ Its load of silt is gradually settling to the bottom, yet still the water seems to drag upon the shores. Every reef of sand, every island of mud, every THE SILENT RIVER 65 overhanging willow or cottonwood or handful of arrow-weed holds out a restraining hand. But slowly, patiently, winding about obstruc- tions, cutting out new channels, creeping where it may not run, the bubbleless water works its way to thesea. The night-winds steal along its shores and pass in and out among its sedges, but there are no whispering voices; and the stars emerge and shine upon the flat floor of water, but there is no lustre. The drear desolation of it! The blare of morning sunlight does not lift the pall, nor the waving illusions of the mirage break the stillness. The Silent River moves on carrying desolation with it; and at every step the waters grow darker, darker with the stain of red—red the hue of decay. It was not through paucity of imagination that the old Spaniards gave the name—Col- orado.* During the first fifty years after its discovery the river was christened many times, but the name that finally clung to it was the one that gave accurate and truthful description. * Colorado is said to be the Spanish translation of the Piman name bugui aguimuti, according to the late Dr. Elliot Coues; but the Spanish word was so obviously used to denote the red color of the stream, that any trans- lation from the Indian would seem superfluous. Sluggish movement, Stillness of river. The river’s name. 66 THE DESERT Its red color. Compared with the Nile. You may see on the face of the globe numer- ous muddy Missouris, blue Rhones, and yellow Tibers ; but there is only one red river and that the Colorado. It is not exactly an earthy red, not the color of shale and clay mixed ; but the red of peroxide of iron and copper, the sang-du- beuf red of oriental ceramics, the deep insistent red of things time-worn beyond memory. And there is more than a veneer about the color. It has a depth that seems luminous and yet is sadly deceptive. You do not see below the surface no matter how long you gaze into it. As well try to see through a stratum of porphyry as through that water to the bottom of the river. To call it a river of blood would be exaggera- tion, and yet the truth lies in the exaggeration. As one walks along its crumbling banks there is the thought of that other river that changed its hue under the outstretched rod of the prophet. How weird indeed must have been the ensan- guined flow of the Nile, with its little waves breaking in crests of pink foam! How strange the shores where the receding waters left upon sand and rock a bordering line of scarlet froth ! But the Colorado is not quite like that—not so ghastly, not so unearthly. It may suggest at times the heavy welling flow of thickening THE SILENT RIVER 67 blood which the sands at every step are trying to drink up; but this is suggestion only, not realization. It seems to hint at blood, and under starlight to resemble it; but the resem- blance is more apparent than real. The Colo- rado is a red river but not a scarlet one. It may be thought odd that the river should change so radically from the clear blue-green of its fountain-head to the opaque red of its desert stream, but rivers when they go wander- ing down to the sea usually leave their moun- tain purity behind them. The Colorado rush- ing through a thousand miles of canyons, cuts and carries seaward with it red sands of shale, granite, and porphyry, red rustings of iron, red grits of carnelian, agate and garnet. All the tributaries come bearing their tokens of red copper, and with the rains the whole red sur- face of the watershed apparently washes into the smaller creeks and thus into the valleys, When the river reaches the desert carrying its burden of silt, it no longer knows the bowlder- bed, the rocky shores, the breaking waterfalls that clarify a stream. And there are no large pools where the water can rest while the silt settles to the bottom. Besides, the desert itself at times pours into the river an even The blood hue. River changes. Red sands and silt. 68 THE DESERT River- banks. ‘* Bottom” lands. deeper red than the canyons. And it does this not through arroyos alone, but also by a wide surface drainage. Often the slope of the desert to the river is gradual for many miles—sometimes like the top of a huge table slightly tilted from the horizontal. When the edge of the table is reached the mesa begins to break into terraces (often cut through by small gullies), and the final descent is not unlike the steps of a Roman circus leading down into the arena. During cloud-bursts the waters pour down these steps with great fury and the river simply acts as a catch-basin for all the running color of the desert. The “ bottom ” lands, forming the immediate banks of the river, are the silt deposits of former years. Often they are several miles in width and are usually covered with arrow-weed, willows, alders, and cottonwoods. The growth is dense if not tall and often forms an almost impenetrable jungle through which are scat- tered little openings where grass and flowers grow and Indians build reed wickiups and raise melons and corn in season. The desert terraces on either side (sometimes there is a row of sand- dunes) come down to meet these ‘‘bottom” lands, | | THE SILENT RIVER 69 and the line where the one leaves off and the other begins is drawn as with the sharp edge of a knife. Seen from the distant mountain tops the river moves between two long ribbons of green, and the borders are the gray and gold mesas of the desert. Afloat and drifting down between these lines of green your attention is perhaps not at first attracted by the water. You are interested in the thickets of alders and the occasional bursts of white and yellow flowers from among the bushes. They are very commonplace bushes, very ordinary flowers ; but how lovely they look as they seem to drift by the boat! How silent again are these clumps of alder and willow! There may be linnets and sparrows among them but they do not make their presence obtrusive in song. A hawk wheels along over the arrow- weed looking for quail, but his wings cut the air without noise. How deathly still everything seems! The water wears into the soft banks, the banks keep sloughing into the stream, but again you hear no splashing fall. And the water itself is just as soundless. There is never a sunken rock to make a little gurgle, never a strip of gravel beach where a wave could charm you with its play. ‘The beat The green bands, Bushes and Jlowers. Soundless water. 70 THE DESERT Wild fowl. Herons and bitterns. of oars breaks the air with a jar, but breaks no bubbles on the water. You look long at the stream and fall to wondering if there can be any life in it. What besides a polywog or a bullhead could live there? Obviously, and in fact—nothing. Perhaps there are otter and beaver living along the pockets in the banks? Yes ; there were otter and beaver here at one time, but they are very scarce to-day. But there are wild fowl ? Yes; in the spring and fall the geese and ducks follow the river in their flights, but they do not like the red water. What proof ? Because they do not stop long in any one place. They swing into a bayou or slough late at night and go out at early dawn. They do not love the stream, but wild fowl on their migratory flights must have water, and this river is the only one between the Rockies and the Pacific that runs north and south. The blue herons and the bitterns do not mind the red mud or the red water, in fact they rather like it; but they were always solitary people of the sedge. They prowl about the marshes alone and the swish of oars drives them into the air with a guttural ‘“‘Quowk.” And there are snipe here, bands of them, flashing their wings in the sun as they wheel over the THE SILENT RIVER 71 red waters or trip along the muddy banks singly or in pairs. They are quite at home on the bars and bayou flats, but it seems not a very happy home for them—that is judging by the absence of snipe talk. The little teeter flies ahead of you from point to point, but makes no twitter, the yellow-leg seldom sounds his mellow three-note call, and the kill-deer, even though you shoot at him, will not cry ‘ Kill-deer!” “¢ Kill-deer !” It may be the season when birds are mute, or it may merely happen so for to-day, or it may be that the silence of the river and the desert is an oppressive influence ; but certainly you have never seen bird-life so hopelessly sad. Even the kingfisher, swinging down in a blue line from a dead limb and skimming the water, makes none of that rattling clatter that you knew so well when you were a child by a New England mill-stream. And what does a king- fisher on such a river as this ? If it were filled with fish he could not see them through that thick water. The voiceless river! From the canyon to the sea it flows through deserts, and ever the seal of silence is upon it. Even the scant life of its borders is dumb—birds with no note, animals Snipe.

The largest river west of the mountains and yet the least known. ‘There are miles upon miles of mesas stretching upward from the stream that no feet have ever trodden, and that possess not a vestige of life of any kind. And along its banks the same tale is told. You float for days and meet with no traces of humanity. When they do appear it is but to emphasize the solitude. An Indian wickiup on the bank, an Indian town; yes, a white man’s town, what impression do they make upon the desert anditsriver? You drift by Yuma and wonder what it is doing there. Had it been built in the middle of the Pacific on a barren rock it could not be more isolated, more hopelessly ‘‘ at sea.” After the river crosses the border-line of Mexico it grows broader and flatter than ever. And still the color seems to deepen. For all its suggestion of blood it is not an unlovely color. On the contrary, that deep red contrasted with the green of the banks and the blue of the sky,, makes a very beautiful color harmony. They are hues of depth and substance—hues that comport excellently well with the character of the river itself. And never a river had more ee ee ee a ee ee HK 8 I ET Oe ae ~ 5 ia a ieee eee Reet ie THE SILENT RIVER 73 character than the Colorado. You may not fancy the solitude of the stream nor its sugges- tive coloring, but you cannot deny its majesty and its nobility. It has not now the babble of the brook nor the swift rush of the canyon water ; rather the quiet dignity that is above conflict, beyond gayety. It has grown old, it is nearing its end ; but nothing could be calmer, simpler, more sublime, than the drift of it down into the delta basin. The mountains are receding on every side, the desert is flattening to meet the sea, and the ocean tides are rising to meet the river. Half human in its dissolution, the river begins to break joint by joint. The change has been gradually taking place for miles and now mani- fests itself positively. The bottom lands widen, many channels or side-sloughs open upon the stream, and the water is distributed into the mouths of the delta. There is a break in the volume and mass—a disintegration of forces. And by divers ways, devious and slow, the crippled streams well out to the Gulf and never come together again. It is not so when the river is at its height with spring freshets. Then the stream is swollen beyond its banks. All the bottom lands for Its majesty. Disinteqra- tion.

And now at the full and the change of the moon, when the Gulf waters come in like a tidal wave, and the waters of the north meet the waters of the south, there is a mighty con- flict of opposing forces. The famous ‘‘ bore” of the river-mouth is the result. When the forces first meet there is a slow push-up of the water which rises in the shape of a ridge or wedge. The sea-water gradually proves itself the greater and the stronger body, and the ridge breaks into a crest and pitches forward with a roar. ‘lhe undercut of the river sweeps away the footing of the tide, so to speak, and flings the top of the wave violently forward. The red river rushes under, the blue tide rushes over. There is the flash and dash of parti-colored foam on the crests, the flinging of jets of spray high in air, the long roll of waves breaking not upon a beach, but upon the back of the river, ‘) ryt is THE SILENT RIVER 75 and the shaking of the ground as though an earthquake were passing. After it is all done with and gone, with no trace of wave or foam remaining, miles away down the Gulf the red river slowly rises in little streams through the blue to the surface. There it spreads fan-like over the top of the sea, and finally mingles with and is lost in the greater body. The river is no more. It has gone down to its blue tomb in the Gulf—the fairest tomb that ever river knew. Something of serenity in the Gulf waters, something of the monumental in the bordering mountains, something of the un- known and the undiscovered over all, make it a fit resting-place for the majestic Colorado. ‘The lonely stream that so shunned contact with man, that dug its bed thousands of feet in the depths of pathless canyons, and trailed its length across trackless deserts, sought out instinctively a point of disappearance far from the madding crowd. The blue waters of the Gulf, the beaches of shell, the red, red mountains standing with their feet in the sea, are still far removed from civilization’s touch. ‘There are no towns or roads or people by those shores, there are no ships upon those seas, there are no dust and smoke of factories in those skies. The Indians The blue tomb. Shores of the Gulf. 76 THE DESERT are there as undisturbed as in the days of Coronado, and the white man is coming but has not yet arrived. The sun still shines on unknown bays and unexplored peaks. There- fore is there silence—something of the hush of the deserts and the river that flows between. CHAPTER V LIGHT, AIR, AND COLOR THESE deserts, cut through from north to south by a silent river and from east to west by two noisy railways, seem remarkable for only a few commonplace things, according to the con- sensus of public opinion. All that one hears or reads about them is that they are very hot, that the sunlight is very glaring, and that there is a sand-storm, a thirst, and death waiting for every traveller who ventures over the first divide. 7 There is truth enough, to be sure, in the heat and glare part of it, and an exceptional truth in the other part of it. It is intensely hot on the desert at times, but the sun is not responsible for it precisely in the manner alleged. The heat that one feels is not direct sunlight so much as radiation from the receptive sands ; and the glare is due not to preternatural bright- ness in the sunbeam, but to there being no re- liefs for the eye in shadows, in dark colors, in 77 Popular ideas of the desert. Sunlight on desert. 78 THE DESERT | Glare and heat. Pure sunlight. heavy foliage. The vegetation of the desert is so slight that practically the whole surface of the sand acts as areflector ; and it is this, rather than the sun’s intensity, that causes the great body of light. The white roads in Southern France, for the surface they cover, are more glaring than any desert sands ; and the sunlight upon snow in Minnesota or New England is more dazzling. In certain spots where there are salt or soda beds the combination of heat and light is bewildering enough for anyone; but such places are rare. White is something seldom seen on desert lands, and black is an unknown quantity in my observations. Even lava, which is popularly supposed to be as black as coal, hasa reddish hue about it. Everything has some color—even the air. Indeed, we shall not comprehend the desert light without a mo- mentary study of this desert air. The circumambient medium which we call the atmosphere is to the earth only as so much ground-glass globe to a lamp—something that breaks, checks, and diffuses the light. We have never known, never shall know, direct sunlight —that is, sunlight in its purity undisturbed by atmospheric conditions. It is a blue shaft fall- ing perfectly straight, not a diffused white or LIGHT, AIR, AND COLOR 79 yellow light ; and probably the life of the earth would not endure for an hour if submitted to its unchecked intensity. The white or yellow light, known to us as sunlight, is produced by the ground-glass globe of air, and it follows readily enough that its intensity is absolutely dependent upon the density of the atmosphere —the thickness of the globe. The cause for the thickening of the aérial envelope lies in the particles of dust, soot, smoke, salt, and vapor which are found floating in larger or smaller proportions in all atmospheres. In rainy countries like England and Holland the vapor particles alone are sufficiently numer- ous to cause at times great obscurity of light, as in the case of fog ; and the air is only com- paratively clear even when the skies are all blue. The light is almost always whitish, and the horizons often milky white. The air is thick, for you cannot see a mountain fifteen miles away in any sharpness of detail. There is a mistiness about the rock masses and a vague- ness about the outline. An opera-glass does not help your vision. The obscurity is not in the eyes but in the atmospheric veil through which you are striving tosee. On the contrary, in the high plateau country of Wyoming, where Atmospher- ic envelope. Vapor particles. 80 THE DESERT Olear air. Dust particles. Hazes, the quantities of dust and vapor in the air are comparatively small, the distances that one can see are enormous. A mountain seventy miles away often appears sharp-cut against the sky, and at sunset the lights and shadows upon its sides look only ten miles distant. But desert air is not quite like the plateau air of Wyoming, though one can see through it for many leagues. It is not thickened by moist- ure particles, for its humidity is almost noth- ing ; but the dust particles, carried upward by radiation and the winds, answer a similar pur- pose. ‘They parry the sunshaft, break and color the light, increase the density of the envelope. Dust is always present in the desert air in some degree, and when it is at its maximum with the heat and winds of July, we see the air as a blue, yellow, or pink haze. This haze is not seen so well at noonday as at evening when the sun rays are streaming through canyons, or at dawn when it lies in the mountain shadows and re- flects the blue sky. Nor does it muffle or ob- scure so much as the moisture-laden mists of Holland, but it thickens the air perceptibly and decreases in measure the intensity of the light. Yet despite the fact that desert air is dust- laden and must be thickened somewhat, there LIGHT, AIR, AND COLOR 81 is something almost inexplicable about it. It seems so thin, so rarefied ; and it is so scent- less—I had almost said breathless—that it is like no air at all. You breathe it without feel- ing it, you look through it without being con-) seeing the scious of its presence. Yet here comes in the cn contradiction. Desert air is very easily recog- nized by the eyes alone. The traveller in Cal- ifornia when he wakes in the morning and glances out of the car-window at the air in the mountain canyons, knows instantly on which side of the Tehachepi Range the train is moy- ing. He knows he is crossing the Mojave. The lilac-blue veiling that hangs about those mountains is as recognizable as the sea air of the Massachusetts shore. And, strange enough, the sea breezes that blow across the deserts all! sea breezes down the Pacific coast have no appreciable ef-|°" er fect upon this air. The peninsula of Lower California is practically surrounded by water, but through its entire length and down the shores of Sonora to Mazatlan, there is nothing | but that clear, dry air. | . IT use the word ‘‘ clear” because one can see so far through this atmosphere, and yet it is not clear or we should not see it so plainly. There is the contradiction again. Is it perhaps 82 THE DESERT Colored air. Different hues. Producing color. the coloring of it that makes it so apparent ? Probably. Even the clearest atmosphere has some coloring about it. Usually it is an inde- finable blue. Air-blue means the most delicate of all colors—something not of surface depth but of transparency, builded up by superim- posed strata of air many miles perhaps in thickness. ‘This air-blue is seen at its best in the gorges of the Alps, and in the mountain distances of Scotland ; but it is not so apparent on the desert. The coloring of the atmosphere on the Colorado and the Mojave is oftener pink, yellow, lilac, rose-color, sometimes fire- red. And to understand that we must take up the ground-glass globe again. It has been said that our atmosphere breaks, checks, and diffuses the falling sunlight like the globe of alamp. It does something more. It acts as a prism and breaks the beam of sun- light into the colors of the spectrum. Some of these colors it deals with more harshly than others because of their shortness and their weakness. The blue rays, for instance, are the greatest in number; but they are the shortest in length, the weakest in travelling power of any of them. Because of their weakness, and because of their affinity (as regards size) with LIGHT, AIR, AND COLOR 83 the small dust particles of the higher air re- gion, great quantities of these rays are caught, refracted, and practically held in check in the upper strata of the atmosphere. We see them massed together overhead and call them the “‘blue sky.” After many millions of these blue rays have been eliminated from the sun- light the remaining rays come down to earth as a white or yellow or at times reddish light, dependent upon the density of the lower atmos- phere. Now it seems that an atmosphere laden with moisture particles obstructs the passage earth- ward of the blue rays, less perhaps than an atmosphere laden with dust. In consequence, when they are thus allowed to come down into the lower atmosphere in company with the other rays, their vast number serves to dom- inate the others, and to produce a cool tone of color over all. So it is that in moist countries like Scotland you will find the sky cold-blue and the air tinged gray, pale-blue, or at twi- light in the mountain valleys, a chilly purple. A dust-laden atmosphere seems to act just the reverse of this. It obstructs all the rays in proportion to its density, but it stops the blue rays first, holds them in the upper air, while Refracted rays. Oold colors, how produced, 84 THE DESERT Warm colors. Sky colors. the stronger rays of red and yellow are only checked in the lower and thicker air-strata near the earth. The result of this is to pro- duce a warm tone of color over all. So it is that in dry countries like Spain and Morocco or on the deserts of Africa and America, you will find the sky rose-hued or yellow, and the air lilac, pink, red, or yellow. I mean now that the air itself is colored. Of course countless quantities of light-beams and dispersed rays break through the aérial envelope and reach the earth, else we should not see color in the trees or grasses or flowers about us; but I am not now speaking of the color of objects on the earth, but of the color of the air. A thing too intangible for color you think ? But what of the sky overhead ? It is only tint- ed atmosphere. And what of the bright-hued horizon skies at sunrise and sunset, the rosy- yellow skies of Indian summer! They are only tinted atmospheres again. Banked up in great masses, and seen at long distances, the air-color becomes palpably apparent. Why then should it not be present in shorter distances, in moun- tain canyons, across mesas and lomas, and over the stretches of the desert plains ? The truth is all air is colored, and that of LIGHT, AIR, AND COLOR 85 the desert is deeper dyed and warmer hued than any other for the reasons just given. It takes on many tints at different times, dependent upon the thickening of the envelope by heat and dust-diffusing winds. I do not know if it is possible for fine dust to radiate with heat alone ; but certain it is that, without the aid of the wind, there is more dust in the air on hot days than at any other time. When the ther- mometer rises above 100° F., the atmosphere is heavy with it, and the lower strata are dancing and trembling with phantoms of the mirage at every point of the compass. It would seem as though the rising heat took up with it countless small dust-particles and that these were respon- sible for the rosy or golden quality of the air- coloring. There is a more positive tinting of the air produced sometimes by high winds. The lighter particles of sand are always being drifted here and there through the aérial regions, and even on still days the whirlwinds are eddying and circling, lifting long columns of dust skyward and then allowing the dust to settle back to earth through the atmosphere. The stronger the wind, and the more of dust and sand, the brighter the coloring. ‘The climax is reached Color pro- duced by dust. Effect of heat.

The dust-particle in itself is sufficient to ac- count for the warmth of coloring in the desert air—sufficient in itself to produce the pink, yel- low, and lilac hazes. And yet I am tempted to suggest some other causes. It is not easy to prove that a reflection may be thrown upward upon the air by the yellow face of the desert beneath it—a reflection similar to that produced by a fire upon a night sky—yet I believe there is something of the desert’s air-coloring derived from that source. Nor is it easy to prove that a reflection is cast by blue, pink, and yellow skies, upon the lower air-strata, yet certain effects shown in the mirage (the water illu- sion, for instance, which seems only the reflec- tion of the sky from heated air) seem to suggest it. And if we put together other casual obser- vations they will make argument toward the same goal. For instance, the common blue haze that we may see any day in the moun- tains, is always deepest in the early morning when the blue sky over it is deepest. At noon when the sky turns gray-blue the haze turns LIGHT, AIR, AND COLOR 87 gray-blue also. The yellow haze of the desert is seen at its best when there is a yellow sunset, and the pink haze when there is a red sunset, indicating that at least the sky has some part in coloring by reflection the lower layers of desert air, Whatever the cause, there can be no doubt about the effect. The desert air is practically colored air. Several times from high mountains I have seen it lying below me like an enormous tinted cloud or veil. A similar veiling of pink, lilac, or pale yellow is to be seen in the gorges of the Grand Canyon; it stretches across the Providence Mountains at noonday and is to be seen about the peaks and packed in the valleys at sunset; it is dense down in the Coahuila Basin ; it is denser from range to range across the hollow of Death Valley ; and it tinges the whole face of the Painted Desert in Arizona. In its milder manifestations it is always present, and during the summer months its appearance is often startling. By that I do not mean that one looks through it as through a highly colored glass. The impression should not be gained that this air is so rose-colored or saffron-hued that one has to rub his eyes and wonder if he is awake. The average unobservant traveller looks Blue, yellow, and pink hazes. The dust- veil. Summer coloring. 88 THE DESERT Local hues. Greens of desert plants. through it and thinks it not different from any other air. But it is different. In itself, and in its effect upon the landscape, it is per- haps responsible for the greater part of what everyone calls ‘‘the wonderful color” of the desert. And this not to the obliteration of local hue in sands, rocks, and plants. Quite independent of atmospheres, the porphyry mountains are dull red, the grease-wood is dull green, the vast stretches of sand are dull yellow. And these large bodies of local color have their influence in the total sum-up. Slight as is the vegetation upon the desert, it is surprising how it seems to bunch together and count as a color-mass. Almost all the growths are ‘“‘evergreen.” The shrubs and the trees shed their leaves, to be sure, but they do it so slowly that the new ones are on before the old ones are off. The general appearance is always green, but not a bright hue, except after prolonged rains. Usually it is an olive, bordering upon yellow. One can hardly estimate what a relieving note this thin thatch of color is, or how monotonous the desert might be without it. It is welcome, for it belongs to the scene, and fits in the color- scheme of the landscape as perfectly as the LIGHT, AIR, AND COLOR 89 dark-green pines in the mountain scenery of Norway. The sands, again, form vast fields of local color, and, indeed, the beds of sand and gravel, the dunes, the ridges, and the mesas, make up the most widespread local hue on the desert. The sands are not ‘‘golden,” except under peculiar circumstances, such as when they are whirled high in the air by the winds, and then struck broadside by thesunlight. Lying quietly upon the earth they are usually a dull yellow. In the morning light they are often gray, at noon frequently a bleached yellow, and at sun- set occasionally pink or saffron-hued. Wavering heat and mirage give them temporary coloring at times that is beautifully unreal. They then appear to undulate slightly like the smooth surface of a summer sea at sunset; and the colors shift and travel with the undulations. The appearance is not common ; perfect calm, a flat plain, and intense heat being apparently the conditions necessary to its existence. The rocks of the upper peaks and those that - make the upright walls of mountains, though small in body of color, are perhaps more varied in hue than either the sands or the vegetation, and that, too, without primary notes as in the Color of sands. Sands in mirage. 90 THE DESERT Color of mountain walls. Weather staining. Influence of the air. Grand Canyon of the Yellowstone. The reds are always salmon-colored, terra-cotta, or Indian red ; the greens are olive-hued, plum-colored, sage-green ; the yellows are as pallid as the leaves of yellow roses. Fresh breaks in the wall of rock may show brighter colors that have not yet been weather-worn, or they may reveal the oxidation of various minerals. Often long strata and beds, and even whole mountain tops show blue and green with copper, or orange with iron, or purple with slates, or white with quartz. But the tones soon become sub- dued. A mountain wall may be dark red with- in, but it is weather-stained and lichen-covered without; long-reaching shafts of granite that loom upward from a peak may be yellow at heart but they are silver-gray on the surface. The colors have undergone years of “ toning down ” until they blend and run together like the faded tints of an Eastern rug. But granted the quantity and the quality of local colors in the desert, and the fact still re- mains that the air is the medium that influ- ences if it does not radically change them all. The local hue of a sierra may be gray, dark red, iron-hued, or lead-colored ; but at a distance, seen through dust-laden air, it may appear LIGHT, AIR, AND COLOR 91 topaz-yellow, sapphire-blue, bright lilac, rose- red—yes, fire-red. During the heated months of summer such colors are not exceptional. They appear almost every evening. I have seen at sunset, looking north from Sonora some twenty miles, the whole tower-like shaft of Baboqui- vari change from blue to topaz and from topaz to glowing red in the course of half an hour. I do not mean edgings or rims or spots of these colors upon the peak, but the whole upper half of the mountain completely changed by them. The red color gave the peak the appearance of hot iron, and when it finally died out the dark dull hue that came after was like that of a clouded garnet. The high ranges along the western side of Arizona, and the buttes and tall spires in the Upper Basin region, all show these warm fire- colors under heat and sunset light, and often in the full of noon. The colored air in conjunc- tion with light is always responsible for the hues. Even when you are close up to the moun- tains you can see the effect of the air in small ways. There are edgings of bright color to the hill-ridges and the peaks ; and in the canyons, where perhaps a sunshaft streams across the shadow, you can see the gold or fire-color of the Peak of Baboqut- vari. Buttes and spires. 92 THE DESERT Sunshafts through canyons. Oomple- mentary hues in shadow, Colored shadows, air most distinctly. Very beautiful are these golden sunshafts shot through the canyons. And the red shafts are often startling. It would seem as though the canyons were packed thick with yellow or red haze. And so in real- ity they are. There is one marked departure from the uni- form warm colors of the desert that should be mentioned just here. It is the clear blue seen in the shadows of western-lying mountains at sunset. This colored shadow shows only when there is a yellow or orange hued sunset, and it is produced by the yellow of the sky casting its complementary hue (blue) in the shadow. Atsea a ship crossing a yellow sunset will show a mar- vellous blue in her sails just as she crosses the line of the sun, and the desert mountains re- peat the same complementary color with equal facility and greater variety. It is not of long duration. It changes as the sky changes, but maintains always the complementary hue, The presence of the complementary color in the shadow is exceptional, however. ‘The shad- ows cast by such objects as the sahuaro and the palo verde are apparently quite colorless ; and so, too, are the shadows of passing clouds. The colored shadow is produced by reflection from ) | LIGHT, AIR, AND COLOR 93 the sky, mixed with something of local color in the background, and also complementary color. It is usually blue or lilac-blue, on snow for ex- ample, when there is a blue sky overhead ; and lilac when shown upon sand or a blue stone road. Perhaps it does not appear often on the Mojave-Colorado because the surfaces are too rough and broken with coarse gravel to make good reflectors of the sky. The fault is not in the light or in the sky, for upon the fine sands of the dunes, and upon beds of fine gypsum and salt, you can see your own shadow colored an absolute indigo ; and often upon bowlders of white quartz the shadows of cholla and grease- wood are cast in almost cobalt hues, All color—local, reflected, translucent, com- plementary—is, of course, made possible by light and has no existence apart from it. Through the long desert day the sunbeams are weaving skeins of color across the sands, along the sides of the canyons, and about the tops of the mountains. They stain the ledges of cop- per with turquoise, they burn the buttes to a terra-cotta red, they paint the sands with rose and violet, and they key the air to the hue of the opal. The reek of color that splashes the western sky at sunset is but the climax of the Blue shad- ows upon salt-beds. How light makes color, 94 THE DESERT Desert sunsets, —_ sun’s endeavor. If there are clouds stretched across the west the ending is usually one of ex- ceptional brilliancy. The reds are all scarlet, the yellows are like burnished brass, the oranges like shining gold. But the sky and clouds of the desert are of such unique splendor that they call for a chapter of their own. CHAPTER VI DESERT SKY AND CLOUDS How silently, even swiftly, the days glide by out in the desert, in the waste, in the wilder- ness! How ‘‘the morning and the evening make up the day” and the purple shadow slips in between with a midnight all stars! And how day by day the interest grows in the long overlooked commonplace things of nature! In afew weeks we are studying bushes, bowlders, stones, sand-drifts—things we never thought of looking at in any other country. And after a time we begin to make mental notes on the changes of light, air, clouds, and blue sky. At first we are perhaps bothered about the inten- sity of the sky, for we have always heard of the ‘‘deep blue” that overhangs the desert; and we expect to see it at any and all times. But we discover that it shows itself in its greatest depth only in the morning before sunrise. Then it is a dark blue, bordering upon purple; and for some time after the sun comes up it holds a 95 Common- place things of nature. 96 THE DESERT The blue sky. Changes in the blue. Dawns on the desert. deep blue tinge. At noon it has passed through a whole gamut of tones and is pale blue, yel- lowish, lilac-toned, or rosy ; in the late after- noon it has changed again to pink or gold or orange ; and after twilight and under the moon, warm purples stretch across the whole reach of the firmament from horizon to horizon. But the changes in the blue during the day have no constancy to a change. There is no fixed purpose about them. ‘The caprices of light, heat, and dust control the appearances. Sometimes the sky at dawn is as pallid as a snow- drop with pearly grays just emerging from the blue ; and again it may be flushed with saffron, rose, and pink. When there are clouds and great heat the effect is often very brilliant. The colors are intense in chrome-yellows, golds, car- mines, magentas, malachite-greens—a body of gorgeous hues upheld by enormous side wings of paler tints that encircle the horizon to the north and south, and send waves of color far up the sky to the cool zenith. Such dawns are sel- dom seen in moist countries, nor are they usual on the desert, except during the hot summer months. The prevailing note of the sky, the one of- tenest seen, is, of course, blue—a color we may , DESERT SKY AND CLOUDS 97 not perhaps linger over because it is so com- mon. And yet how seldom it is appreciated ! Our attention is called to it in art—in a haw- thorn jar as large as a sugar-bowl, made in a certain period, in a certain Oriental school. The esthetic world is perhaps set agog by this ceramic blue. But what are its depth and purity compared to theethereal blue! Yet the color is beautiful in the jar and infinitely more beantiful in the sky—that is beautiful in itself and merely as color. It is not necessary that it should mean anything. Line and tint do not always require significance to be beautiful. There is no tale or text or testimony to be tort- ured out of the blue sky. It isa splendid body of color ; no more. You cannot always see the wonderful quality of this sky-blue from the desert valley, because it is disturbed by reflections, by sand-storms, by lower air-strata. The report it makes of itself when you begin to gain altitude on a mountain’s side is quite different. At four thousand feet the blue is certainly more positive, more intense, than at sea-level ; at six thousand feet it begins to darken and deepen, and it seems to fit in the saddles and notches of the mountains like a block of lapis lazuli; at eight thousand feet it Blue as a color.

The night sky at this altitude is al- most weird in its purples. A deep violet fits up close to the rim of the moon, and the orb itself looks like a silver wafer pasted upon the sky. The darkening of the sky continues as the height increases. If one could rise to, say, fifty thousand feet, he would probably see the sun only as a shining point of light, and the firma- ment merely as a blue-black background. The diffusion of light must decrease with the grow- ing thinness of the atmospheric envelope. At what point it would cease and the sky become perfectly black would be difficult to say, but certainly the limit would be reached when our atmosphere practically ceased to exist. Space from necessity must be black except where the straight beams of light stream from the sun and the stars. The bright sky-colors, the spectacular effects, are not to be found high up in the blue of the dome. The air in the zenith is too thin, too free from dust, to take deep colorings of red and orange. Those colors belong near the earth, along the horizons where the aérial envelope is dense. The lower strata of atmosphere are in DESERT SKY AND CLOUDS 99 fact responsible for the gorgeous sunsets, the tinted hazes, the Indian-summer skies, the hot September glows. These all appear in their splendor when the sun is near the horizon-line and its beams are falling through the many miles of hot, dust-laden air that lie along the surface of the earth. The air at sunset after a day of intense heat-radiation is usually so thick that only the long and strong waves of color can pass through it. The blues are al- most lost, the neutral tints are missing, the greens are seen but faintly. The waves of red and yellow are the only ones that travel through the thick air with force. And these are the colors that tell us the story of the desert sunset. Ordinarily the sky at evening over the desert, when seen without clouds, shows the colors of the spectrum beginning with red at the bottom and running through the yellows, greens, and blues up to the purple of the zenith. In cool weather, however, this spectrum arrange- ment seems swept out of existence by a broad band of yellow-green that stretches half way around the circle. It is a pale yellow fading : into a pale green, which in turn melts into a pale blue. In hot weather this pallor is changed to something much richer and deeper.
