Years ago the maps of the United States depicted a vast region west of the Missouri River stippled with dots, which were supposed to imitate sand, and marked with the portentous legend, "Great American Desert." As sturdy pioneers pushed their settlements farther and farther westward, the great American desert began to shrink in size until the roseate descriptions of prospectors and land speculators led one to believe that this whole region needed only a touch of the plough and the harrow to produce the most bountiful crops grown anywhere in the world.

Nevertheless, the great domain extending from the twenty-five-hundred-foot level to the crest of the Sierra Nevada Mountains is a region so deficient in rainfall that, for the greater part, ordinary foodstuffs will not grow without irrigation; so farming must be confined mainly to the flood-plains of the rivers. Here and there considerable areas have been made fertile by capturing rivers, damming their streams so as to create great reservoirs, and then measuring out the waters to the farm lands below. The Salt River dam in Arizona, recently completed, will supply water to two thousand square miles, or about twenty-five thousand fifty-acre farms.

But in spite of all that man has done and can do to make this region fruitful, not far from half a million square miles will ever remain barren so far as the production of foodstuffs is concerned. Now this whole region, irrigated lands included, does not produce more wealth than the State of New York alone—possibly it does not produce so much.

Indirectly, however, it is worth more than two thousand million dollars yearly to the rest of the United States; for it is a great highland whose rims, the Sierra Nevada and the Rocky Mountain ranges, are about two miles high. Now, these lofty ranges wring almost every drop of moisture from the rain-bearing winds of the Pacific Ocean, leaving them too dry to shed any moisture over the eastern half of the United States. Because of this great mountain barrier, the winds that bring rain and bountiful crops to the Mississippi Valley and the Atlantic slope, follow an easier passage, flowing directly from the Gulf of Mexico and the Caribbean Sea. And the copious rains are the chief wealth of this midland region.

But the arid western highland possesses a great wealth of its own—a wealth whose influence is world-wide, for it is one of the world's chief storehouses of gold, silver, and copper. Gold and silver are the mediums of commercial transactions, and copper is the chief medium for the transmission of electric power. These metals, therefore, are quite as necessary as are iron and steel. Moreover, this great waste, a seeming incubus on the face of the earth, is each year disclosing more and more of its mineral and agricultural wealth.

Gold is the most widely disseminated of all metals, and is said to be where you find it. That this statement is true has been demonstrated many times, especially during the last few decades. In the north it has been found in the frozen ground of Alaska and Siberia, in the south in the sands on the surf-beaten shores of Tierra del Fuego and in the reefs of the Transvaal, while it is found in numerous places lying between these extremes.

The vast tract of land in the western part of the United States whence most of these metals are obtained has been the scene of many tragedies. It is an inhospitable region, scanty in both animal and vegetable life, where climatic conditions call for heroic daring on the part of those who would search out its hidden mysteries; it is a land of death-dealing mirages, yet containing untold wealth for the miner, and likewise for the husbandman who can irrigate the fallow parched surface.

The bold prospector has unearthed in many places of southern Nevada gold-bearing rock assaying thousands of dollars to the ton, the result being the building up of cities and towns and the construction of connecting railroads to meet the demands of the growing commerce. Until recently, silver was the principal metal sought and found in the State of Nevada; but now gold is king, and his throne has been shifted from one desert camp to another, each laying claim to his abundant presence, while new claimants are ever bringing new treasures into light.

The two most valuable deposits of the precious metals now known in Nevada are at Tonopah and Goldfield, the discovery of the first having been made in 1901 and of the latter in the following year. Some of the Goldfield ore has assayed as high as thirty thousand dollars per ton, and so rich were many of its ores that they were sacked and carefully guarded until landed at the reduction works. In one year and a half from the discovery of gold at Goldfield the output reached four million dollars.

These mines of the Nevada deserts excel in the richness and abundance of their ores, while in the future these camps bid fair to outrival in development all other sections of the United States. A few years ago the southern part of the Silver State was considered utterly worthless and a region to be shunned like a charnel-house, on account of its barren and dangerous character. Now it is the Mecca of the gold-seeker.

These mines have already made many a poor man wealthy and many a wealthy man a millionaire. Each hillock, ledge, or ravine holds a possible fortune, and no hardship and peril is too great for the prospector lured by the hope of a rich find. The prosperous desert mining town, first built of canvas and rough lumber, is soon replaced by a better class of buildings, and water is brought through long miles of pipe from the nearest available source. Anon, electric-lighting and other modern conveniences are added, thereby making life more tolerable in a fierce climate of heat and cold, of fiercer winds and blinding dust.

Not only is gold found in these desert wastes, but borax, nitre, sulphur, silver, salt, soda, opals, garnets, turquoises, onyx, and marble form a part of its resources. Rich gold mines have built the towns of Randsburg and Johannesburg in the midst of the Mohave desert, while finds of rich ore made elsewhere are of frequent occurrence. It is thought that in the near future sufficient nitre can be obtained from the deserts of California and Nevada to render the United States independent of Chile, from whose desert, Atacama, the world's chief supply of this mineral is now obtained.

Perhaps there is no part of the United States more healthy and at the same time more deadly than the southeastern part of California, embraced in those indefinite areas called the Mohave and Colorado deserts. That life and death should lay claim to the same regions with equal strength seems somewhat of a riddle, but a careful investigation of the conditions will make good the claims of both. Here are regions rivalling the Sahara in heat, lack of water, and barrenness, and in many parts as difficult to traverse; regions full of surprises in deceptive mirages, peculiar vegetation, strange animal life, occasional cloud-bursts, purity and exhilarating effects of atmosphere, charm of ever-changing colors reflected from the mountains, wealth of floral display in early spring, and marvellous fertility of soil when touched by the magic wand of water. All these and a certain weirdness of beauty difficult to define give these great wastes a peculiar attraction of their own which only those who have spent much time there can understand and appreciate.

For the dread white plague in its early stages there is no medicine and no other climate that can equal the pure, healing atmosphere of these deserts. A new lease of life may be gained by the nerve-racked man or woman who will lay aside all home worries and spend a few months at some congenial home on one or another of these deserts.
