Wolf, as well as Mukoki, has good cause for what he does.

You might call it animal vengeance.

Did you ever notice that a half of one of his ears is gone?
And if you thrust back his head you will find a terrible sear in his throat, and from his left side just back of the fore leg a chunk of flesh half as big as my hand has been torn away.

We caught Wolf in a lynx trap, Mukoki and I.He wasn't much more than a whelp then--about six months old, Mukoki said.
And while he was in the trap, helpless and unable to defend himself, three or four of his lovely tribe jumped upon him and tried to kill him for breakfast.

We hove in sight just in time to drive the cannibals off.
We kept Wolf, sewed up his side and throat, tamed him--and to-morrow night you will see how Mukoki has taught him to get even with his people." It was two hours later when Rod and Wabigoon extinguished the candles and returned to their blankets.
