After listening to wolf tales by residents of the frontier settlements rather than by real men of the “bush,” one might almost expect to see a couple of these bloodthirsty animals harrying the rear of every band of Caribou and keeping up a relentless pursuit. However, during a sojourn of six months on one of the best Caribou ranges in Keewatin, where trapping has very little effect on Wolves, I saw just one of these animals alive, heard the howling on several occasions, and noted a single Caribou that had probably been killed by them. It is far from a common experience for the resident trappers to witness actual pursuit by Wolves or even to find their kills. The following instances, related by Fred Schweder, Jr., comprised his only direct observations on Wolves in pursuit of Caribou up to and including 1947, when he was eighteen years old. During the northward migration in May, 1945, a silent black Wolf pursued a band of 100 Caribou over the ice of Windy Bay. At one time it came within 100 feet, but thereafter they forged ahead. After half a mile the band split up, and the Wolf desisted. In October, 1946, Fred noticed a Caribou fighting off two Wolves on the ice of Nueltin Lake near its outlet. It used both horns and hoofs against its attackers. While one Wolf was in front, the other would try to get in the rear of the Caribou and hamstring it. This went on for two hours until darkness hid the scene. The next morning the Caribou was dead and half eaten. On October 16, 1947, a white Wolf was seen in pursuit of four fast-moving Caribou near Simons’ Lake. It was about half a mile in their rear, and presently halted, probably by reason of catching sight of Fred. November 7, 1947, was a blizzardy day; the air was full of drifting snow. Under these conditions a gray Wolf chased a buck and a doe right into the dooryard of one of Fred’s trapping camps 10 miles north of Windy River. It was only about 30 feet behind them. When the buck broke through the ice of a little creek, the Wolf went right past it in pursuit of the doe. The latter nearly ran into Fred’s toboggan, and he shot it at a distance of 20 feet. The Wolf came within 40 feet, but by the time it was recognized as not just another Caribou, it was 100 feet away. Fred then shot but merely wounded it, the sight being off his rifle. Meanwhile the buck escaped, but 3 miles away Fred met with it again and secured it. He recognized it as the same animal because at both encounters it was limping from a previous wound and was hornless as well. In late November Fred found two fullgrown bucks and a doe on the ice of Windy Lake, where they had been killed by Wolves. The bucks were antlered and had probably met their end several weeks previously. Yet their flesh was so musky and unpalatable, in consequence of the rutting season, that it had not been devoured. A long trail of blood and hair led to the spot where the doe had fallen, apparently a couple of weeks previously; it was still only half eaten.
