She gave her reins a shake and her horse started on a brisk canter. As she sped away she listened for his following hoof beats, for she made no doubt he would pursue her, explain his conduct, and ask her pardon. The request not to keep up with her he would, of course, set aside. David would have obeyed it, but this man of the mountains, at once domineering and stupid, would take no command from any woman. She kept her ear trained for the rhythmic beat in the distance and decided when she heard it she would increase her speed and not let him catch her till she was up with the train. Then she would coldly listen to his words of apology and have the satisfaction of seeing him look small, and probably not know what to say.

Only it didn't happen that way. He made no attempt to follow. As she galloped across the plain he drew his horse to a walk, his face dark and frowning. Her scorn and blush had left his blood hot. Her last words had fired his anger. He had known her antagonism, seen it in her face on the night when Bella was sick, felt its sting when she turned from him to laugh with the others. And it had stirred him to a secret irritation. For he told himself she was only a baby, but a pretty baby, on whose brown and rosy face and merry slits of eyes a man might like to look. Now he gazed after her swearing softly through his beard and holding his horse to its slowest step. As her figure receded he kept his eyes upon it. They were long-sighted eyes, used to great distances, and they watched, intent and steady, to see if she would turn her head.

"Damn her," he said, when the dust of the train absorbed her. "Does she think she's the only woman in the world?"

After supper that evening Susan called David over to sit on the edge of her blanket. This was a rare favor. He came hurrying, all alight with smiles, cast himself down beside her and twined his fingers in her warm grasp. She answered his hungry glance with a sidelong look, glowingly tender, and David drew the hand against his cheek. Nobody was near except Daddy John and Courant, smoking pipes on the other side of the fire.

"Do you love me?" he whispered, that lover's text for every sermon which the unloving find so irksome to answer, almost to bear.

But now she smiled and whispered,

"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.
