It was a moment of grave peril for Ruth Fielding.

Again and again she beat her mount, and again and again he went up into the air, landing stiff-legged, and with all four feet close together. Then she swung the stinging lash across the face of the stallion.

It was a cruel blow and it laid open the satiny, black skin of the angry brute right across his nose. He squealed and fell back. The pony whirled and again Ruth struck at their common enemy.

Lashing the stallion seemed a better thing than punishing her own frightened mount, and as the mad horse circled her the girl struck again and again, once cutting open the stallion’s shoulder and drawing blood in profusion.

The fight was not won so easily, however. The pony danced around and around trying to keep his heels to the stallion; the latter endeavored to get in near enough to use either his fore-hoofs in striking, or his teeth to tear the girl or her mount.

And then Ruth unexpectedly heard a shout. Somebody at the top of his voice ordered her to “Lie down on his neck—I’m going to fire!”

She saw nothing; she had no idea where this prospective rescuer stood; but she was wise enough to obey. She seized the pony’s mane and lay as close to his neck as possible. The next instant the report of a heavy rifle drowned even the squealing of the stallion.

He had risen on his hind feet, his fore-hoofs beating the air, the foam flying from his lips, his yellow teeth gleaming. A more frightful, threatening figure could scarcely be imagined, it seemed to the girl of the Red Mill in her dire peril.

At the rifle shot he toppled over backward, crashing to the earth with a scream that was almost human. There he lay on his back for a minute.

Out of the brush hobbled the young man named Royal. He was getting around without his crutches now. The gun in his hand was still smoking.
