Plainly it was a signal well understood. In a second the whole herd was on its feet. In another, with lightning precision, it had formed itself into a compact circle, using the watchful leader as the basic point of its formation. The calves, butted unceremoniously into the centre, hustled one upon the other, with uplifted muzzles over each other’s shoulders and mild eyes staring with startled fright. The outer rim of the circle became a fringe of sullen lowering foreheads, angry eyes and keen horns jutting formidably from snow-powdered manes of dark hair.
Not a member of the musk-ox herd, to the youngest calf, but knew very well against what enemy the old bull had so suddenly marshalled them into fighting phalanx. For some moments, however—long, tense, vigilant moments—nothing appeared. Then at last, through the driving flakes, they caught sight of several gaunt, leaping forms, gray and shadowy, which swept down upon them in silence out of the storm.
With terrible suddenness and speed they came, these leaping forms, as if they would hurl themselves blindly upon the massed herd. But the line of lowered horns never flinched or wavered, and with a short snarl from their leader the wolves swerved, just in time to escape a savage thrust from the old bull. They swerved, strung out into line, and went loping round the circle, their narrowed, greenish, merciless eyes glaring into the obstinate ones of the musk-oxen. Again and again they circled the rampart of horns, again and again they drew off and swept up furiously to the assault, hoping to find some weak point in the defences—some timorous young cow who would shrink and swerve at their assault and open a breach in the line. But there was no cow in that herd afflicted with any such suicidal folly. The snow-spotted, lowering line of heads waited unshaken, and presently the wolves—there were seven of them—bunched together a few paces from the circle and seemed to consider. Two of them sat down upon their haunches with their tongues hanging out, and eyed the rampart of horned fronts evilly, while the others stood with their heads together, or prowled restlessly back and forth. They might, indeed, with the vast leaping power of their long legs and muscular haunches, have sprung clear over the line of defence, and gained in two seconds the helpless calves in the centre; but they knew what that would mean. The herd would turn in upon them in a blind, uncalculating fury and trample them underfoot. For the moment, therefore, they hung wavering in irresolution, looking for a sign from the leader of the pack.
In the meantime the man had found his valley hollow and the shelter of the expected colony of dwarf firs. Here the snow lay soft and undrifted. In a recess of the fir-thicket he trod it down with his snowshoes, and made haste to build himself a little fire of dead sticks. Above his head, above the shrouded fir-tops, above the rim of the hollow, the storm drove by unabated; but the snowflakes that escaped from the tumult to filter down into this retreat were too light and fine and dry to interfere with the fire. In two or three minutes the flames were crackling up clear and free, with little spittings and fine hissings where the flakes fell at their thin edges.
Having collected a pile of dry sticks within easy reach, the man stretched a couple of stitched caribou hides on poles to form a sloping roof over his head, cooked himself a hasty stew of pemmican and biscuit, made a hearty meal, and squatted before the fire with his back against his sledge, to smoke and wait. He knew how to wait, like an Indian, when there was anything to be gained by it, and his heart, weary of pemmican, was set on fresh meat.
There was no sign of the storm breaking; there was no use hunting in the storm. There was nothing to fear, for it was now three weeks since he had seen sign of the wolves which had eaten his dogs, and he knew that they had ranged off on the trail of the vanished caribou. There was nothing to do. He was warm and filled, and free from care. Some hundred miles or so away there was a post and human companionship, to which he looked forward with unhurried content. In due time he would arrive there and find it, as always before, unchanged, like all else in that land of inevitable recurrence. Meanwhile—this afternoon, perhaps, or to-morrow—he would shoot a young musk-ox cow. He drew his furs well about him and dozed off to sleep, knowing that the moment the fire began to get dangerously low an unfailing instinct would bid him awake to tend it.
While he slept, the storm drove unrelenting over the place of his retreat, and kept heaping the thin dry snow in fringes and wreaths upon the shaggy, lowering fronts of the musk-ox phalanx. From time to time, a massive head would shake off the burden and emerge black and menacing. And always, with unwavering vigilance, the army of angry eyes and short sharp horns confronted the group of discontented wolves.
Now, as it chanced, the trapper was wrong in his assumption as to the wolves. The truth—which would have made a great difference in his calculations had he known it—was that they had been cautiously trailing him ever since he left his hut. But they knew something of man, those wolves, and they feared him. They were not yet quite mad with hunger, so they had not yet quite plucked up courage to reveal themselves to him, still less to commit themselves to an open attack. They dreaded his eye, they dreaded his sharp, authoritative voice. They dreaded the strange, menacing smell of him. They dreaded his mysterious power of striking invisibly from very far off. Had they had any choice, they would far rather have been running down the caribou than trailing this solitary trapper. But the craving belly is a hard master, and they had no choice but to hasten wherever it scourged them on. Moreover, they knew along the trail of the man there were liable to be pickings, for man, a fastidious feeder, never eats all he kills.
When at last the trail of the man had led them into that of the musk-oxen, the pack had been glad. So much the more, therefore, their disappointed rage, when they found the herd ready for their attack, and too strong, in point of numbers and experienced leadership, to be stampeded. Seeing the prey so near, with each moment of their discomfiture their hunger and their fury grew.
Suddenly, without visible sign or warning, it seemed to boil over all at once. The whole pack sprang together, swift as the snap of a whip, into a compact mass, and hurled itself straight upon the circle of lowered horns. The charge looked irresistible. It seemed that the most dauntless must cringe and shrink before it.
