The wolf let out an unmistakable yelp of pain and limped off, howling. Freckles kept on in pursuit and the revolver was soon far behind. The beast she pursued was now in a bad way; but the girl dared not ride back to search for her lost weapon. She did not propose that the wolf—after such a fight—should escape. Ruth was bent upon his destruction.

The wolf, however, dodged and doubled, so that the pony could not trample it, even had he wished to come to such close quarters. The clashing teeth of the savage animal warned Freckles to keep his distance, however; and it was plain to Ruth that she must dismount to finish the beast. If only she had some weapon——

What was that heap on the prairie ahead? Bones! hundreds of them! Some accident had befallen a bunch of cattle here in the past and their picked skeletons had been flung into a heap. The wolf ran for refuge behind this pile and Ruth immediately urged Freckles toward the spot.

She leaped from the saddle, tossing the bridle reins over his head upon the ground and ran to seize one of the bigger bones. It was the leg bone of a big steer and it made a promising club.

But even as she seized upon this primitive weapon the wolf made a final stand. He appeared around the far side of the pile. He saw that the girl was afoot, and with a snarl he sprang upon her.

Ruth uttered an involuntary shriek, and ran back. But she could not reach Freckles. The wolf’s hot breath steamed against her neck as she ran. He had missed her by a hair!

The girl whirled and faced him, the club poised in both her hands, determined to give battle. Her situation was perilous in the extreme. Afoot as she was, the beast had the advantage, and he knew this as well as she did. He did not hurry, but approached his victim with caution—fangs bared, jaws extended, his wounds for the moment forgotten.

CHAPTER XXII—SERVICE COURAGEOUS

There was no escape from the wolf’s attack, even had Ruth desired to evade the encounter. The beast’s flaming eyes showed his savage intention only too plainly. To turn and run at this juncture would have meant death for the brave girl. She stood at bay, the heavy bone poised to strike, and let the creature approach.

He leaped, and with all her strength—and that was not slight—she struck him. The wolf was knocked sideways to the ground. She followed up the attack with a second and a third blow before he could recover his footing.
