Something like ten minutes were occupied in this stealthy advance of the horse, at the end of which time he stood so that his head was directly over the shoulders of the prostrate man, who still lay as motionless as a statue.

"Hooh!" exclaimed the rider, holding himself ready for any demonstration upon the part of the suspected white man. But the latter never stirred, although he shivered a little at the fear that the mustang might place his hoof upon him.

Tom's peculiar peril will be understood when it is stated that the Apache was master of the situation from the instant they came in sight of each other. Had the fugitive fired at him the moment he caught sight of his horse, he might have tumbled him to the ground, but it would have brought the rest of the party around him in an instant. As matters now stood, the Apache would have fired at the first movement he made, no matter how dexterous, to draw his hand from beneath his body, and so Tom bided his time.

"Hooh!"

This was repeated several times, when the warrior tried to force his mustang to step upon him; but the animal was too timid to be forced into doing such a repugnant thing, and, when angrily urged thereto, leaped clear of the body with a sniff of terror, and galloped several rods before he could be brought round and compelled to face the unknown again. This seemed to convince the Apache that the man was dead, and without any further hesitation he slid down from the back of his horse, and advanced to the figure for the purpose of scalping him.

He had just stooped down, knife in hand, when the form turned like a flash. There came a blinding flash, then a report and a cry, almost together, and Tom Hardynge seemed to leap up from the ground as if a bomb had exploded beneath him, and, dashing toward the mustang, seized his rein and vaulted upon his back before the animal really knew what had taken place.

It was a daring deed, but it succeeded to perfection. The scout had not only extinguished his foe, but had captured his horse as well. The sound of the pistol might reach the ears of other Apaches, but he cared nothing for that. He was as well mounted as they, and, with the start which he had gained, they were welcome to do all they could. In view of this, it was impossible for him to restrain his exultation, and the moment he realized that he was fairly astride of the mustang he let out a shout that might have been heard a mile away. The steed which bore him was an excellent one, and he had no fear of being overtaken by any of them. He knew in what direction to take his flight, and away he sped with his horse upon a dead run. He scarcely drew rein until daylight broke over the prairie, when he found himself pursuing a direction parallel with the river, and making good headway toward the point where he hoped his own matchless Thundergust was awaiting him.

Hardynge scarcely halted during the greater portion of the next day, except when his mustang required it, and shortly after the sun crossed the meridian he was gratified at catching sight of the rolling prairie and wooded hills where he had turned his horse loose nearly a week before. While at a distance he gave utterance to several sharp whistles, which produced the response he desired, the beautiful glossy mustang galloping forth to meet him with every appearance of delight. The creature had taken good care of himself during his absence, having feasted upon the rich, succulent grass, and was in the best possible condition.

Turning the Indian horse loose Tom bestowed no further attention upon him, but leaped upon his favorite animal and galloped away to the rocks where he had carefully concealed his saddle and riding gear and where they had lain untouched while he was gone.

Just as he dismounted, his eye rested upon a piece of dried buffalo-skin which was pinned against a tree, the inner side turned outward. The first glance told him there was something unusual, and his curiosity led him to approach and scan it closely. There was some writing scrawled upon it, which he read with little difficulty. The words were startling enough, and as the hunter finished them he exclaimed, in a frightened undertone:
