When evening came the great transformation began. With the first deepening of color the desert's silent heart began to beat in expectation of its hour of beauty. Its bleak detail was lost in shrouding veils and fiery reflection. The earth floor became a golden sea from which the capes reared themselves in shapes of bronze and copper. The ring of mountains in the east flushed to the pink of the topaz, then bending westward shaded from rosy lilac to mauve, and where the sunset backed them, darkened to black. As the hour progressed the stillness grew more profound, the naked levels swept out in wilder glory, inundated by pools of light, lines of fire eating a glowing way through sinks where twilight gathered. With each moment it became a more tremendous spectacle. The solemnity attendant on the passage of a miracle held it. From the sun's mouth the voice of God seemed calling the dead land to life. Each night the travelers gazed upon it, ragged forms gilded by its radiance, awed and dumb. Its splendors crushed them, filling them with nostalgic longings. They bore on with eyes that were sick for a sight of some homely, familiar thing that would tell them they were still human, still denizens of a world they knew. The life into which they fitted and had uses was as though perished from the face of the earth. The weak man sunk beneath the burden of its strangeness. Its beauty made no appeal to him. He felt lost and dazed in its iron-ringed ruthlessness, dry as a skeleton by daylight, at night transformed by witchfires of enchantment. The man and woman, in whom vitality was strong, combatted its blighting force, refused to be broken by its power. They desired with vehemence to assert themselves, to rebel, not to submit to the sense of their nothingness. They turned to one another hungry for the life that now was only within themselves. They had passed beyond the limits of the accustomed, were like detached particles gone outside the law of gravity, floating undirected through spaces where they were nothing and had nothing but their bodies, their passions, themselves. To a surface observation they would have appeared as stolid as savages, but their nerves were taut as drawn violin strings. Strange self-assertions, violences of temper, were under the skin ready to break out at a jar in the methodical routine. Had the train been larger, its solidarity less complete, furious quarrels would have taken place. With an acknowledged leader whom they believed in and obeyed, the chances of friction were lessened. Three of them could meet the physical demands of the struggle. It was David's fate that, unable to do this, he should fall to a position of feeble uselessness, endurable in a woman, but difficult to put up with in a man.
