Yet she could not help from thinking that perhaps Jib was right in his diagnosis of the case. The man might be too far gone to save. Neither physician nor medicines might be able to retard the fever. It seemed to have already worn the unfortunate to his very skeleton. If he died, would the mystery of the Tintacker Mine, and of Uncle Jabez’s money, ever be explained?

Meanwhile she bathed and bathed again the fevered face and hands of the unfortunate. This was all that relieved him. He was quiet for some minutes after each of these attentions. The water in the bucket became warm, like that in the canteen. Ruth thought she could risk going to the rivulet for another supply. So she stuck the barrel of the gun into her belt and taking the empty pail set out to find the stream.

She closed the door of the sick man’s cabin very carefully. It was not far to the water and she had filled the pail and was returning when she heard a scratching noise nearby, and then a low growl. Casting swift glances of apprehension all about her, she started to run to the cabin; but when she got to the trail, it was at the cabin door the peril lay!

It was no harmless, cowardly coyote this time. Perhaps it had not been a coyote who had dug there when she and Jib rode up to the camp. She obtained this time a clear view of the beast.

It was long, lean and gray. A shaggy beast, with pointed ears and a long muzzle. When he turned and glared at her, growling savagely, Ruth was held spellbound in her tracks!

“A wolf!” she muttered. “A wolf at the door!”

The fangs of the beast were exposed. The jaws dripped saliva, and the eyes seemed blood-red. A more awful sight the girl had never seen. This fierce, hungry creature was even more terrifying in appearance than the bear that had chased her in the cañon. He seemed, indeed, more savage and threatening than the puma that Jib had roped that forenoon as they rode over to Tintacker.

He turned squarely and faced her. He was not afraid, but seemed to welcome her as an antagonist worthy of his prowess. He did not advance, but he stood between Ruth and the door of the sick man’s cabin. She might retreat, but in so doing she would abandon the unfortunate to his fate. And what that fate would be she could not doubt when once she had glimpsed the savage aspect of the wolf.

CHAPTER XXI—A PLUCKY FIGHT

Ruth had already set down the bucket of water and drawn the heavy pistol from her belt. The girls had been trying their skill with six-shooters at the ranch at odd times, and she knew that she stood a good chance of hitting the big gray wolf at ten or twelve yards. The beast made no approach; but his intention of returning to the door of the cabin where the sick man lay, if she did not disturb him, was so plain that Ruth dared not desert the helpless patient!
