He wondered if he could pull the gun up by means of a string he found in his pocket, and resolved to try. Making a loop in one end of the string he lowered it with care, until it rested close to the gun, and then he did his best to slide the string along under the barrel. This was comparatively easy, for the barrel was tilted up against a rock.

The wolves watched the maneuvering with interest, and no sooner did the gun begin to shift than three leaped forward, snarling angrily. One snapped at the barrel of the piece, one at the butt, and a third at the trigger. An instant later came the report heard by the Rovers and John Barrow.

The shot was almost a deadly one, not alone for two of the wolves, but also for Jasper Grinder, who was not expecting the gun to go off. The piece was loaded with buckshot, which tore through the sides of two of the beasts, and then passed upward into the tree-branches, taking the former school-teacher in the left shoulder.

"I'm shot!" gasped Jasper Grinder, and almost fell from his perch. But he managed to save himself, and hung in a crotch, weak and almost helpless, the blood flowing freely and dripping to the ground, where the wolves licked it up eagerly. A few had retreated at the report of the gun, but now all came back, snarling and yelping more wildly than ever.

It must be confessed that Jasper Grinder's position was truly unfortunate. The loss of blood was fast rendering him unconscious, and he was in mortal terror of dropping down and being devoured.

"Help!" he called feebly. "Help! For the love of Heaven, help me!"

Just as his senses were leaving him he heard a distant cry, and looking in that direction, saw John Barrow and Dick approaching, followed by Tom and Sam.

"The wolves have Grinder treed," cried the guide. "I'll give 'em something to remember us by!"

He had a double-barreled shotgun, and he let drive twice in quick succession, firing into two groups of the beasts, and killing two and wounding several others. Then Dick fired, bringing down another. Tom and Sam also discharged their pieces, and added three others to the dead or dying.

This slaughter was too much for the remaining wolves, hungry as they were, and in a twinkle they ran off into the timber, howling dismally.
