She did not hear him, but waved her hand, and gave him a bright smile that was brimming with unshed tears. It seemed like instant, daring suicide in him to stand on that swaying, clattering house as it moved off irresponsibly down the plane of vision. She watched him till he was out of sight, a mere speck on the horizon of the prairie; and then she turned her horse slowly into the road, and went her way into the world alone.

The man stood on the platform, and watched her as he whirled away—a little brown girl on a little brown horse, so stanch and firm and stubborn and good. Her eyes were dear, and her lips as she smiled; and her hand was beautiful as it waved him good-by. She was dear, dear, dear! Why had he not known it? Why had he left her? Yet how could he stay? His mother was dying perhaps. He must not fail her in what might be her last summons. Life and death were pulling at his heart, tearing him asunder.

The vision of the little brown girl and the little brown horse blurred and faded. He tried to look, but could not see. He brought his eyes to nearer vision to fix their focus for another look, and straight before him whirled a shackly old saloon, rough and tumble, its character apparent from the men who were grouped about its doorway and from the barrels and kegs in profusion outside. From the doorway issued four men, wiping their mouths and shouting hilariously. Four horses stood tied to a fence near by. They were so instantly passed, and so vaguely seen, that he could not be sure in the least, but those four men reminded him strongly of the four who had passed the schoolhouse on Sunday.

He shuddered, and looked back. The little brown horse and the little brown girl were one with the little brown station so far away, and presently the saloon and men were blotted out in one blur of green and brown and yellow.

He looked to the ground in his despair. He must go back. He could not leave her in such peril. She was his to care for by all the rights of manhood and womanhood. She had been put in his way. It was his duty.

But the ground whirled by under his madness, and showed him plainly that to jump off would be instant death. Then the thought of his mother came again, and the girl's words, "I am nothing to you, you know."

The train whirled its way between two mountains and the valley, and the green and brown and yellow blur were gone from sight. He felt as if he had just seen the coffin close over the girl's sweet face, and he had done it.

By and by he crawled into the car, pulled his slouch hat down over his eyes, and settled down in a seat; but all the time he was trying to see over again that old saloon and those four men, and to make out their passing identity. Sometimes the agony of thinking it all over, and trying to make out whether those men had been the pursuers, made him feel frantic; and it seemed as if he must pull the bell-cord, and make the train stop, and get off to walk back. Then the utter hopelessness of ever finding her would come over him, and he would settle back in his seat again and try to sleep. But the least drowsiness would bring a vision of the girl galloping alone over the prairie with the four men in full pursuit behind. "Elizabeth, Elizabeth, Elizabeth!" the car-wheels seemed to say.

Elizabeth—that was all he had of her. He did not know the rest of her name, nor where she was going. He did not even know where she had come from, just "Elizabeth" and "Montana." If anything happened lo her, he would never know. Oh! why had he left her? Why had he not made her go with him? In a case like that a man should assert his authority. But, then, it was true he had none, and she had said she would run away. She would have done it too. O, if it had been anything but sickness and possible death at the other end—and his mother, his own little mother! Nothing else would have kept him from staying to protect Elizabeth.

What a fool he had been! There were questions he might have asked, and plans they might have made, all those beautiful days and those moon-silvered nights. If any other man had done the same, he would have thought him lacking mentally. But here he had maundered on, and never found out the all-important things about her. Yet how did he know then how important they were to be? It had seemed as if they had all the world before them in the brilliant sunlight. How could he know that modern improvements were to seize him in the midst of a prairie waste, and whirl him off from her when he had just begun to know what she was, and to prize her company as a most precious gift dropped down from heaven at his feet?
