“If you want any more proof,” Frank went on coolly, “take a look over by that bush yonder. That’s where we saw him digging first. You’ll likely find there’s a burrow, with the snow and dirt thrown out.”

“Yes,” added Bluff, “and if you look sharp, perhaps now you’ll discover a few specks of blood on the snow along the trail the dog made when he skipped out.”

No one took the trouble to find out. The two men with Nackerson must have been already convinced that the boys were not guilty. As for the big hunter, he did not wish to put himself in a place where he might have to admit that he had wronged them.

“Don’t believe a word of it, I tell you,” he persisted, as though bent on making trouble. “You’ve got a pretty slick tongue, youngster; but you can’t fool me. I cut my eye-teeth long ago.”

“I suppose you are a gentleman of considerable experience in the woods,” Frank observed, still hoping to conciliate the man, who he saw had been making a liberal use of his pocket flask, as usual. “But we have told you only the truth, and say again that your dog was not harmed by us.”

Frank shut his jaws hard. Bluff edged up alongside, as though it was his earnest desire to be on the firing line if there was going to be trouble.

At that critical moment a voice was heard, saying:
