Over many wide regions of the south-western desert country of Arizona and New Mexico lies an eternal spell of silence and mystery. Across the sand-ridges come many foreign things, both animate and inanimate, which are engulfed in its immensity, which frequently disappear for all time from the sight of men, blotted out like a bird which flies free from a lighted room into the outside darkness. As though in compensation for that which it has taken, the desert from time to time allows new marvels, riven from its vitals, to emerge.
Though death-still, it has a voice which calls ceaselessly to those human hearts tuned to its messages: hostile and harsh, it draws and urges; repellent, it profligately awards health and wealth; inviting, it kills. And always it keeps its own counsel; it is without peer in its lonesomeness, and without confidants; it heaps its sand over its secrets to hide them from its flashing stars.
You see the bobbing ears of a pack-animal and the dusty hat and stoop shoulders of a man. They are symbols of mystery. They rise briefly against the skyline, they are gone into the grey distance. Something beckons or something drives. They are lost to human sight, perhaps to human memory, like a couple of chips drifting out into the ocean. Patient time may witness their return; it is still likely that soon another incarnation will have closed for man and beast, that they will have left to mark their passing a few glisteningly white bones, polished untiringly by tiny sand-chisels in the grip of the desert winds. They may find gold, but they may not come in time to water. The desert is equally conversant with the actions of men mad with gold and mad with thirst.
To push out along into this immensity is to evince the heart of a brave man or the brain of a fool. The endeavour to traverse the forbidden garden of silence implies on the part of the agent an adventurous nature. Hence it would seem no great task to catalogue those human beings who set their backs to the gentler world and press forward into the naked embrace of this merciless land. Yet as many sorts and conditions come here each year as are to be found outside.
Silence, ruthlessness, mystery--these are the attributes of the desert. True, it has its softer phases--veiled dawns and dusks, rainbow hues, moon and stars. But these are but tender blossoms from a spiked, poisonous stalk, like the flowers of the cactus. They are brief and evanescent; the iron parent is everlasting.
