Perhaps the day after the trapper had shot his first deer he discovered fine footprints like a child's hand on the snow around the carcass. He recognises the trail of otter or pekan or mink. It would be useless to bait a deadfall with meat when an unpolluted feast lies on the snow. The man takes one of his small traps and places it across the line of approach. This trap is buried beneath snow or brush. Every trace of man-smell is obliterated. The fresh hide of a deer may be dragged across the snow. Pomatum or castoreum may be daubed on everything touched. He may even handle the trap with deer-hide. Pekan travel in pairs. Besides, the dead deer will be likely to attract more than one forager; so the man sets a circle of traps round the carcass.

The next morning he comes back with high hope. Very little of the deer remains. All the flesh-eaters of the forest, big and little, have been there. Why, then, is there no capture? One trap has been pulled up, sprung, and partly broken. Another carried a little distance off and dumped into a hollow. A third had caught a pekan; but the prisoner had been worried and torn to atoms. Another was tampered with from behind and exposed for very deviltry. Some have disappeared altogether.

Among forest creatures few are mean enough to kill when they have full stomachs, or to eat a trapped brother with untrapped meat a nose-length away.

The French trapper rumbles out some maledictions on le sacré carcajou. Taking a piece of steel like a cheese-tester's instrument, he pokes grains of strychnine into the remaining meat. He might have saved himself the trouble. The next day he finds the poisoned meat mauled and spoiled so that no animal will touch it. There is nothing of the deer but picked bones. So the trapper tries a deadfall for the thief. Again he might have spared himself the trouble. His next visit shows the deadfall torn from behind and robbed without danger to the thief.

Several signs tell the trapper that the marauder is the carcajou or wolverine. All the stealing was done at night; and the wolverine is nocturnal. All the traps had been approached from behind. The wolverine will not cross man's track. The poison in the meat had been scented. Whether the wolverine knows poison, he is too wary to experiment on doubtful diet. The exposing of the traps tells of the curiosity which characterizes the wolverine. Other creatures would have had too much fear. The tracks run back to cover, and not across country like the badger's or the fox's.

Fearless, curious, gluttonous, wary, and suspicious, the mischief-maker and the freebooter and the criminal of the animal world, a scavenger to save the northland from pollution of carrion, and a scourge to destroy wounded, weaklings, and laggards—the wolverine has the nose of a fox, with long, uneven, tusk-like teeth that seem to be expressly made for tearing. The eyes are well set back, greenish, alert with almost human intelligence of the type that preys. Out of the fulness of his wrath one trapper gave a perfect description of the wolverine. He didn't object, he said, to being outrun by a wolf, or beaten by a respectable Indian, but to be outwitted by a little beast the size of a pig with the snout of a fox, the claws of a bear, and the fur of a porcupine's quills, was more than he could stand.

In the economy of nature the wolverine seems to have but one design—destruction. Beaver-dams two feet thick and frozen like rock yield to the ripping onslaught of its claws. He robs everything: the musk-rats' haycock houses; the gopher burrows; the cached elk and buffalo calves under hiding of some shrub while the mothers go off to the watering-place; the traps of his greatest foe, man; the cached provisions of the forest ranger; the graves of the dead; the very tepees and lodges and houses of Indian, half-breed, and white man. While the wolverine is averse to crossing man's track, he will follow it for days, like a shark behind a ship; for he knows as well as the man knows there will be food in the traps when the man is in his lodge, and food in the lodge when the man is at the traps.

But the wolverine has two characteristics by which he may be snared—gluttony and curiosity.

After the deer has disappeared the trapper finds that the wolverine has been making as regular rounds of the traps as he has himself. It is then a question whether the man or the wolverine is to hold the hunting-ground. A case is on record at Moose Factory, on James Bay, of an Indian hunter and his wife who were literally brought to the verge of starvation by a wolverine that nightly destroyed their traps. The contest ended by the starving Indians travelling a hundred miles from the haunts of that "bad devil—oh—he—bad devil—carcajou!" Remembering the curiosity and gluttony of his enemy, the man sets out his strongest steel-traps. He takes some strong-smelling meat, bacon or fish, and places it where the wolverine tracks run. Around this he sets a circle of his traps, tying them securely to poles and saplings and stakes. In all likelihood he has waited his chance for a snowfall which will cover traces of the man-smell.

Night passes. In the morning the man comes to his traps. The meat has been taken. All else is as before. Not a track marks the snow; but in midwinter meat does not walk off by itself. The man warily feels for the hidden traps. Then he notices that one of the stakes has been pulled up and carried off. That is a sign. He prods the ground expectantly. It is as he thought. One trap is gone. It had caught the wolverine; but the cunning beast had pulled with all his strength, snapped the attached sapling, and escaped. A fox or beaver would have gnawed the imprisoned limb off. The wolverine picks the trap up in his teeth and hobbles as hard as three legs will carry him to the hiding of a bush, or better still, to the frozen surface of a river, hidden by high banks, with glare ice which will not reveal a trail. But on the river the man finds only a trap wrenched out of all semblance to its proper shape, with the spring opened to release the imprisoned leg.
