The two riders were half-way down the street now, a tall bay forging steadily ahead of a little Mexican mustang until ten feet or more intervened between the two horses.  The train jerked; the Wells Fargo man, with his truck alongside the express-car far ahead, yelled something to the man who had taken his packages aboard.

“The bay wins,” grinned the fat man.  “It looks—­Gad!  It’s a woman!”

Greek saw that it was a woman in khaki riding-habit, and that the spurs she wore were gnawing into her horse’s flanks.  He began to take a sudden, stronger interest.  He leaned farther out, hardly realizing that he had called to the conductor to hold the train a moment.  For it was at last clear that these were not mad people, but merely a couple of the dwellers of the desert anxious to catch Number 1.  But the conductor had waved his orders and was swinging upon the slowly moving steps.  From the windows of the train a score of heads were thrust out, a score of voices raised in shouting encouragement.  And down to the tracks the woman and the man behind her rushed, their horses’ feet seeming never to touch the ground.

A bump, a jar, a jerk, and the Limited was drawing slowly away from the station.  The woman was barely fifty yards away.  As she lifted her head Greek saw her face for the first time.  And, having seen her ride, he pursed his lips into a low whistle of amazement.

“Why, she’s only a kid of a girl!” gasped the fat man.  “And, say, ain’t she sure a peach!”

Greek didn’t answer.  He was busy inwardly cursing the conductor for not waiting a second longer.  For it was obvious to him that the girl was going to miss the train by hardly more than that.

But she had not given up.  She had dropped her head again and was rushing straight toward the side of the string of cars.  Greek held his breath, a swift alarm for her making his heart beat trippingly.  He did not see how she could stop in time.

Again a clamor of voices from the heads thrust out of car windows, warning, calling, cheering.  And then suddenly Greek sat back limply.  The thing had been so impossible and in the end so amazingly simple.

Not ten feet away from the train she had drawn in her horse’s reins, “setting up” the half-broken animal upon his four feet, bunched together so that with the momentum he had acquired he slid almost to the cars.  As he stopped the girl swung lightly from the saddle and, seeming scarcely to have put foot upon the sandy soil, caught the hand-rail as the car came by and swung on to the lowest step.  The man behind her caught up her horse’s reins, whirled, sweeping his hat off to her, and turned back.

“Which is some riding, huh?” chuckled the fat man, his own head withdrawn as he reached for his beer-glass.

“What’s the excitement?” Roger’s interest had not been great enough to send him to the window.

“Some people trying to catch the train,” Greek told him, shortly.  For some reason, not clear to himself, he did not care to be more definite.
