The flat, which Andy knew very well—having driven the bunch of cattle whose footprints had so elated Miss Allen—he crossed uneasily. There were so many outlets to this rich little valley. He tried several of them, which took time; and always when he came to soft earth and saw no track of the hoof that turned in toward the other, he would go back and ride into another gulch. And when you are told that these were many, and that much of the ground was rocky, and some was covered with a thick mat of grass, you will not be surprised that when Andy finally took up her trail in the canyon farthest to the right, it was well towards noon. He followed her easily enough until he came to the next valley, which he examined over and over before he found where she had left it to push deeper into the Badlands. And it was the same experience repeated when he came out of that gulch into another open space.

He came into a network of gorges that would puzzle almost anyone, and stopped to water his horse and let him feed for an hour or so. A man's horse meant a good deal to him, down here on such a mission, and even his anxiety could not betray him into letting his mount become too fagged.

After a while he mounted and rode on without having any clue to follow; one must trust to chance, to a certain extent, in a place like this. He had not seen any sign of the Kid, either, and the gorges were filling with shadows that told How low the sun was sliding down the sky. At that time he was not more than a mile or so from the canyon up which Miss Allen was toiling afoot toward the sun; but Andy had no means of knowing that. He went on with drooping head and eyes that stared achingly here and there. That was the worst of his discomfort—his eyes. Lack of sleep and the strain of looking, looking, against wind and sun, had made them red-rimmed and bloodshot. Miss Allen's eyes were like that, and so were the eyes of all the searchers.

In spite of himself Andy's eyes closed now. He had not slept for two nights, and he had been riding all that time. Before he realized it he was asleep in the saddle, and his horse was carrying him into a gulch that had no outlet—there were so many such!—but came up against a hill and stopped there. The shadows deepened, and the sky above was red and gold.

Andy woke with a jerk, his horse having stopped because he could go no farther. But it was not that which woke him. He listened. He would have sworn that he had heard the shrill, anxious whinney of a horse not far away. He turned and examined the gulch, but it was narrow and grassy and had no possible place of concealment, and save himself and his own horse it was empty. And it was not his own horse that whinnied—he was sure of that. Also, he was sure that he had-not dreamed it. A horse had called insistently. Andy knew horses too well not to know that there was anxiety and rebellion in that call.

He waited a minute, his heart beating heavily. He turned and started back down the gulch, and then stopped suddenly. He heard it again—shrill, prolonged, a call from somewhere; where, he could not determine because of the piled masses of earth and rock that flung the sound riotously here and there and confused him as to direction.

Then his own horse turned his head and looked toward the left, and answered the call. From far off the strange horse made shrill reply. Andy got down and began climbing the left-hand ridge on the run, tired as he was. Not many horses ranged down in here—and he did not believe, anyway, that this was any range horse. It did not sound like Silver, but it might be the pigeon-toed horse of Miss Allen. And if it was, then Miss Allen would be there. He took a deep breath and went up the last steep pitch in a spurt of speed that surprised himself.

At the top he stood panting and searched the canyon below him. Just across the canyon was the high peak which Miss Allen had climbed afoot. But down below him he saw her horse circling about in a trampled place under a young cottonwood.

You would never accuse Andy Green of being weak, or of having unsteady nerves, I hope.

But it is the truth that he felt his knees give way while he looked; and it was a minute or two before he had any voice with which to call to her. Then he shouted, and the great hill opposite flung back the echoes maddeningly.
