Recovering himself with an effort, he raised a piercing call for help.

All grew black about him. He no longer saw the brilliant flashes of lightning that at intervals lighted up the scene, nor heard the voices of his companions frantically calling upon him to come back. The mountaineer's sinewy fingers had closed in an iron-grip over Tad Butler's throat.

CHAPTER VI

THE CAPTURE OP THE HORSE THIEF

"There they are!" cried Ned Rector, a flash of lightning having disclosed the man kneeling over Tad Butler. "He's got Tad down!"

But Lige Thomas did not even hear the warning words. He, too, during the momentary illumination, had caught the significance of the scene.

With a mighty leap he hurled himself upon the body of the crouching mountaineer, both going down in a confused heap, with the unfortunate Tad underneath.

Ned Rector was only a few seconds behind the guide. While the two men were straggling in fierce embrace, he sprang to them, and, grabbing Tad by the heels, drew him from beneath the bodies of the desperate combatants. But Ned's heart sank when he saw Lige drop over backward, with the mountaineer on top.

With a courage born of the excitement of the moment, Ned clasped both hands under the fellow's chin, jerking his head violently backwards. So sudden was the jolt that the lad distinctly heard the man's neck snap, and, for the moment, believed he had broken it entirely.

However, the mountaineer's tough coating of muscle made such a result impossible. Yet he had sustained a jolt so severe that, for the time being, he found himself absolutely helpless, and wholly at the mercy of his antagonists.
