He was relieved when both men turned toward the dusty black trail down the grade to Medicine Hat, from which came the soft pad of a cantering horse.

A stodgy little broncho was loping easily along, a woman seated astride its broad back. At such a distance Stamford's only impression was of a perfect equestrienne, mingled with some surprise that a woman should appear in such a scene. Then he became aware of her perfect physique, an overflowing vitality, and an intense pleasure in the very act of riding. It attracted him strangely, for modesty of stature had all his life imposed an undue modesty of manner in his relationship with the other sex. The uncouth shouts of the cowboys, the rumbling trample of the cattle up the gangways and in the sand-strewn cars, the threatened explosion of the past minute, sank into the background of his mind as he watched.

The longer the silence in his little group, the more the approaching woman looked to him like a studio arrangement that must utterly fail, in the incongruity of its essential parts, to melt into a natural picture. It was impossible to fit her into that background of untilled hills, dead grass, barren waste, though there could never be awkwardness where she was concerned.

Cockney Aikens raised his head with a jerk and stared, frowning in a puzzled way.

Dakota merely glanced at the supple rider and transferred his eyes to Cockney's lace.

"Here's your Yankee, Mr. Aikens," he grinned, and lounged across the tracks to the loading pens, laughing as he went.

The look on Cockney's face warned Stamford to silence, but he trotted to the end of the platform and offered his hand to assist the woman to alight. With a quick flick of her body she stood beside him, rewarding him with a gentle smile as she rearranged her skirts.

"Thank you. Matana will stand by herself."

Her eyes had scarcely paused on Stamford before passing on to the big rancher. Aikens had not moved. With lowered head he was staring at her. She stooped in some confusion and brushed her skirt to smoother lines about her limbs. Then her head went up, and with a nervous laugh she moved swiftly along the platform.

"Mary, what are you doing here?"
