Three foes assailed the trapper alone in the wilds. The first danger was from the wolf-pack. The second was the Indian hostile egged on by rival traders. This danger the French trapper minimized by identifying himself more completely with the savage than any other fur trader succeeded in doing. The third foe was the most perverse and persevering thief known outside the range of human criminals. 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.
