"That's no owl," gasped Rob, "it's Indians!"

As he realized how badly he had been fooled, his pony topped the rise. To any one below in the hollow, the outline of the pony and the boy showed blackly against the stars. Suddenly a sound like an angry bee in full flight hummed close to Rob's ear, and the next moment there came a sharp report behind him.

Instantaneously the hoots to the right and left flanks redoubled, and began closing in. All at once one of the birdlike cries sounded right in front of the escaping white boy.

He was hemmed in by Indians!

The craft of the red men had proven too much for Rob. Even the darkness had not prevented their unerringly tracking him. By their skillful woodcraft and keenness of perception they had succeeded in discovering him and surrounding him.

For an instant Rob's heart stood still. Then, as a second shot whizzed by his ear, aimed by the unseen marksman below, he urged his pony on over the rise.

The advance, however, over the rocky ground sounded as loud as the approach of a squadron of cavalry. Wild cries and yells rang out on every side of the boy. What was he to do?

One of those inspirations born in moments of keen stress came to him in his extremity. If all went well, he would fool the Indians yet, hard as they were to deceive.

Slipping noiselessly from his pony as he rode under a dark clump of piñon trees, the boy turned it loose. The little animal, to his surprise, immediately turned backward, heading round toward the camp. But this turn of events, at first alarming, ultimately proved to be the very best thing that could have happened for Rob, who had at first hoped that the pony would trot forward.

The Indians, hearing its rapid footsteps galloping back, reasoned that Rob, realizing that he was headed off, had turned his mount in a desperate effort to escape that way. Yelling like demons, and discharging their rifles in an almost continuous fusillade, the Indians wheeled and rode after the retreating pony. Naturally, the more they shouted and fired, the faster the little animal ran, and every step took them farther from Rob, who was crouching under his piñon trees.
