"Of course, silly David."

"Ah, Susan, you're awakening," he breathed in a shaken undertone.

She again let the soft look touch his face, sweet as a caress. From the other side of the fire Courant saw it, and through the film of pipe smoke, watched. David thought no one was looking, leaned nearer, and kissed her cheek. She gave a furtive glance at the man opposite, saw the watching eyes, and with a quick breath like a runner, turned her face to her lover and let him kiss her lips.

She looked back at the fire, quiet, unflurried, then slowly raised her lids. Courant had moved his pipe and the obscuring film of smoke was gone. Across the red patch of embers his eyes gazed steadily at her with the familiar gleam of derision. Her tenderness died as a flame under a souse of water, and an upwelling of feeling that was almost hatred, rose in her against the strange man.

CHAPTER IV

The last fording of the river had been made, and from the summit of the Red Buttes they looked down on the long level, specked with sage and flecked with alkaline incrustings, that lay between them and the Sweetwater. Across the horizon the Wind River mountains stretched a chain of majestic, snowy shapes. Desolation ringed them round, the swimming distances fusing with the pallor of ever-receding horizons, the white road losing itself in the blotting of sage, red elevations rising lonely in extending circles of stillness. The air was so clear that a tiny noise broke it, crystal-sharp like the ring of a smitten glass. And the sense of isolation was intensified as there was no sound from anywhere, only a brooding, primordial silence that seemed to have remained unbroken since the first floods drained away.

Below in the plain the white dots of an encampment showed like a growth of mushrooms. Near this, as they crawled down upon it, the enormous form of Independence Rock detached itself from the faded browns and grays to develop into a sleeping leviathan, lost from its herd and fallen exhausted in a sterile land.

Courant was curious about the encampment, and after the night halt rode forward to inspect it. He returned in the small hours reporting it a train of Mormons stopped for sickness. A boy of fifteen had broken his leg ten days before and was now in a desperate condition. The train had kept camp hoping for his recovery, or for the advent of help in one of the caravans that overhauled them. Courant thought the boy beyond hope, but in the gray of the dawn the doctor mounted, and with Susan, David, and Courant, rode off with his case of instruments strapped to his saddle.

The sun was well up when they reached the Mormon camp. Scattered about a spring mouth in the litter of a three days' halt, its flocks and herds spread wide around it, it was hushed in a sullen dejection. The boy was a likely lad for the new Zion, and his mother, one of the wives of an elder, had forgotten her stern training, and fallen to a common despair. Long-haired men lolled in tent doors cleaning their rifles, and women moved between the wagons and the fires, or sat in rims of shade sewing and talking low. Children were everywhere, their spirits undimmed by disaster, their voices calling from the sage, little, light, half-naked figures circling and bending in games that babies played when men lived in cliffs and caves. At sight of the mounted figures they fled, wild as rabbits, scurrying behind tent flaps and women's skirts, to peep out in bright-eyed curiosity at the strangers.
