"It's something clear and strong, sometimes shallow and then again deeper than you can guess. And when there's anything in the way, it gathers all its strength and sweeps over it. It's a mighty force. You have to be stronger than it is—and more cunning too—to stop it in the way it wants to go."

Above their heads the sky glowed in red bars, but down in the stream's hollow the dusk had come, cool and gray. She was suddenly aware of it, noticed the diminished light, and the thickening purplish tones that had robbed the trees and rocks of color. Her warm vitality was invaded by chill that crept inward and touched her spirit with an eerie dread. She turned quickly and ran through the bushes calling back to him, "I must hurry and get supper. They'll be waiting. Bring the pail."

Courant followed slowly, watching her as she climbed the bank.

CHAPTER II

For some days their route followed the river, then they would leave it and strike due west, making marches from spring to spring. The country was as arid as the face of a dead planet, save where the water's course was marked by a line of green. Here and there the sage was broken by bare spaces where the alkali cropped out in a white encrusting. Low mountains edged up about the horizon, thrusting out pointed scarps like capes protruding into slumbrous, gray-green seas. These capes were objects upon which they could fix their eyes, goals to reach and pass. In the blank monotony they offered an interest, something to strive for, something that marked an advance. The mountains never seemed to retreat or come nearer. They encircled the plain in a crumpled wall, the same day after day, a low girdle of volcanic shapes, cleft with moving shadows.

The sun was the sun of August. It reeled across a sky paled by its ardor, at midday seeming to pause and hang vindictive over the little caravan. Under its fury all color left the blanched earth, all shadows shrunk away to nothing. The train alone, as if in desperate defiance, showed a black blot beneath the wagon, an inky snake sliding over the ground under each horse's sweating belly. The air was like a stretched tissue, strained to the limit of its elasticity, in places parting in delicate, glassy tremblings. Sometimes in the distance the mirage hung brilliant, a blue lake with waves crisping on a yellow shore. They watched it with hungry eyes, a piece of illusion framed by the bleached and bitter reality.

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.
