The wolf crouched, growling and showing his fangs. If the girl approached too near he would spring upon her. Or, if she fired and wounded him but slightly she feared he would give chase and pull her down in a few seconds. She very well know that she could not hope to distance the beast if once he started to pursue her.

This was indeed a dreadful situation for a tenderly nurtured girl. The wolf looked to be fully as large as Tom Cameron’s mastiff, Reno. And Ruth wished with all her heart (as this comparison flashed through her mind) that the mastiff was here to give battle to the savage beast.

But it were vain to think of such impossibilities. If anything was to be done to drive off the wolf at the cabin door, she must do it herself. Yet she dared not make the attack here in the open, and afoot. If she approached near enough to him to make her first shot sure and deadly, the beast gave every indication of opening the attack himself.

And, indeed, he might spring toward her at any moment. He was growing impatient. He had scented the helpless man inside the shack and—undisturbed—would soon burrow under the door and get at him. Although not so cowardly as a coyote, the wolf seldom attacks human beings unless they are helpless or the beast is driven to desperation by hunger. And gaunt as this fellow was, there was plenty of small game for him in the chapparel.

Thus, Ruth was in a quandary. But she saw plainly that she must withdraw or the wolf would attack. She left the bucket of water where it stood and withdrew back of the nearest hut. Once out of the wolf’s sight, but still holding the revolver ready, she looked hastily about. Her pony, hobbled by Jib, had not wandered far. Nor had Freckles seen or even scented the savage marauder.

Ruth spied him and crept away from the vicinity of the wolf, keeping in hiding all the time. She soon heard the beast clawing at the bottom of the door and growling. He might burst the door, or dig under it, any moment now!

The last few yards to the pony Ruth made at a run. Freckles snorted his surprise; but he knew her and was easily caught. The frightened girl returned the revolver to her belt and removed the hobbles. Then she vaulted into the saddle and jerked the pony’s head around, riding at a canter back toward the cabin.

The wolf heard her coming and drew his head and shoulders back out of the hole he had dug. In a few minutes more he would be under the door and into the cabin, which had, of course, no floor but the hard-packed clay. He started up and glared at the pony and its rider, and the pony began to side-step and snort in a manner which showed plainly that he did not fancy the vicinity of the beast.

“Whoa, Freckles! Steady, boy!” commanded Ruth.

The cow pony, trained to perfection, halted, with his fore feet braced, glaring at the wolf. Ruth dropped the reins upon his neck, and although he winced and trembled all over, he did not move from the spot as the girl raised the heavy pistol, resting its barrel across her left forearm, and took the best aim she could at the froth-streaked chest of the wolf.
