In all such stories certain traits appear to betray a common and romantic origin. Thus, the imaginary pack always terrifies you by reason of its numbers; scores of grim shapes flit through shadowy woods or draw a circle of green eyes to flash back the firelight. The real pack is invariably small, since it consists of a single wolf family. The mother wolf leads; the dog wolf is in the same neighborhood, but commonly hunts by himself; with the mother go her last litter of cubs and a few grown wolves of a former litter that have not yet found their mates. From five to eight wolves make the ordinary pack. Where game is plentiful (leading to large wolf families) ten or twelve may occasionally follow the mother; but such a large pack is exceptional, even in winter. In the subarctic region, where uncounted caribou move north in spring or south in autumn, several different packs hang about the flanks of the migrating herds; but never at such times do the wolves unite or mass, and being well fed with the best of venison they are uncommonly peaceable.

Another romantic trait of the terrible packs of the tale is that they always howl when they charge home. It is one of the marked characteristics of the real wolf that he is silent when stalking or running down game of any kind. His howling has nothing to do with his hunting, being reserved for social or other occasions; he wastes no breath in noise, as hounds do, when he means to overtake anything. Indeed, one of the most uncanny qualities of a wolf is the fleet, soundless, mysterious way he has of appearing where he is least expected. In the northern wilderness this is the typical way of it:

You are swinging along campward, following your lonely snowshoe trail over ice-locked waters, through snow-filled woods, when there comes a vague change or chill in the air. It is the moment when we say that night is falling, when gray shadows rise from the lake to meet other shadows flowing down from the hills; and that is the moment when you can count most surely on hearing the first howl of a stirring wolf. It is a creepy sound in such a place or moment, especially when it is followed by the clamor of a pack, a cry that carries far over the silent places, and that may come from the hills on either side or from the trail behind you. However far away it may be, there is always a menace in the wolf’s challenge; your nerves tingle as you stop to listen.

If you believe your imagination now, the fierce outcry grows louder, sweeps nearer; but if you trust your ears, you will know that it remains stationary, dying away where it began. Those noisy brutes are only proclaiming their ego, like awakened dogs; and having marked their direction you move homeward again, noting the increasing tension of the brief winter twilight, so different from the summer gloaming with its velvet shadows, its thrush song, its lingering light. Presently you have lost all thought of the distant wolves; if you remember them at all, you are thinking of the morrow’s hunt, how you will go back and search out their trail, when suddenly and most startlingly—there they are! And always the disturbing part of such a meeting is this: the wolves are behind you, in front of you, and on either side, before you have the first inkling that they are anywhere near.

So open is the forest here, and so white the snow, that you fancied a rabbit could hardly move without betraying himself to your eyes; yet without noise or shadow of motion surely that is a wolf watching you over a fallen log, where you can see only his eyes and his cocked ears. On the other side of the trail a bush quivers as a wolf creeps under it, but you catch no sure glimpse of him. Look behind you, and a gray something vanishes; then the woods are motionless again. And that is all you will see or hear of your ferocious wolf pack, unless, perchance, you run away; in which event some cub-wolf that knows no better may take a jump or two after you.

These timber wolves of the north are immensely interesting brutes, tireless, powerful, unbelievably cunning. To follow their trail is to have increasing respect for their keenness, their vim, their hair-trigger way of meeting any emergency. Once when I was tracking a solitary dog wolf, an uncommonly big brute, and lazy after eating his fill of venison, I came out of the woods to a frozen lake, and saw him ambling along near shore a few hundred yards ahead of me. He happened to be passing under an icy ledge, utterly unsuspicious of man or danger, when a bullet struck the ice, ping! at his heels.

That was a range shot, a bit shy, and I expected him to give me another chance; but he never even looked around to see where the ping or the bang came from. Almost, it seemed, before the report could reach him he had tried the ledge twice, only to find it overhigh for a standing jump and too slippery to climb. Without an instant’s hesitation he darted out on the lake for a flying start, whirled to the right-about, came at the ledge, and went superbly over it into thick cover. The ledge was over eight feet in the rise, and from the foot of it to his take-off was another ten feet; but in a flash he had measured his leap and taken it rather than expose himself any longer in the open.

Another time I saw a single wolf throw and kill a buck, a matter which called for skill as well as strength, and he did it so easily that one was left wondering what chance a man would have with a few brutes of that kind rolling in upon him. In numbers or when made reckless by hunger our timber wolves might well prove terrible enemies; but the simple fact is that they have no desire to meet a man. They are afraid of him, and avoid him even when they are hungry. Again and again, when wolves have howled about my winter camp at night, I have gone out and given them opportunity for a man hunt; but though they are much bolder by night than by day, they have never, save in one peculiar instance, shown any evidence of a hostile or dangerous disposition. And then they scared me properly, making me know how a man might feel if he were running with a pack of wolves at his heels.

The startling exception came one winter afternoon as I was crossing a frozen lake in a snowstorm. It was almost dusk when I came out of the woods, hurrying because I had far to go, and started fair across the middle of the lake. Soon the wind was blowing the snowflakes in level lines; what with snow and darkened air it became difficult to keep one’s bearings, and in order to see my way better I edged in nearer and nearer to the weather shore.

Two or three times, as I headed steadily up the lake, I had a vague impression that something moved in the woods, and moved so as to keep abreast of me; but the flying flakes interfered with clear vision till I began to come under the lee of a point of evergreens. Then I surely saw a creeping motion among the trees on my left, and stopped dead in my tracks to watch it. The next instant the underbrush was ripped open in a dozen places, and a pack of wolves rushed out. One turned and loped swiftly between me and the point ahead; another that I dared not watch sped down the lake, at a broad angle from the course of the first; the rest spread into a fan-shaped formation that broadened swiftly and must soon spring its ends together like a trap. In a twinkling every avenue of escape to the woods was shut by a wolf; there was left only a fight or a straightaway run across the ice.
