world’s roof, were their moments of greatest peril. Close to the edge of the hole they sprawled; and always one or another kept anxious watch, scanning with mild, bright eyes the menacing solitude, wherein they seemed the only things alive.

About this time, from one of a group of tiny, snow-covered mounds huddled along the base of the Little Hills, emerged a man. He crawled forth on all fours from the tunnel of his doorway, and stood up and peered about him. His squat figure was clothed and hooded in furs. His little, twinkling eyes, after clearing themselves from the smoke and smart of the thick air within the igloo, could see further through the gloom than even the eyes of the bear. He noted the fall of the wind, the savage intensity of the cold, and his eyes brightened with hope. He had no fear of the cold, but he feared the hunger which was threatening the lonely village. During the long rage of the wind, the supply of food in his igloo had run low. He welcomed a cold which would close up most of the seals’ breathing-holes, and force more numerous visitors to the few holes that they could keep open. For some moments he stood motionless, peering and listening as the bear had done. Suddenly he too caught that far-off light crashing of brittle ice. On the instant he turned and crawled hastily back into the hut.

A moment later he reappeared, carrying two weapons, besides the long knife stuck in his girdle. One of these was an old Hudson Bay Company’s musket. The other was a spear of spliced bone, with a steel head securely lashed to it. Powder and ball for the musket were much too precious to be expended, except in some emergency wherein the spear might fail. Without waiting for a repetition of the sounds, he started off at once unerringly in the direction whence they had come. He knew that air-hole; he could find it in the delusive gloom without the aid of landmark. For some way he went erect and in haste, though as soundlessly as the bear. Then, throwing himself flat, he followed exactly the bear’s tactics, till, at last, peering cautiously over a jagged ice-ridge, he, too, could make out the quarry watchfully coming and going about the brink of the air-hole.

From this point onward the man’s movements were so slow as to be almost imperceptible. But for his thick covering of furs, his skin tough as leather and reeking with oil, he would have been frozen in the midst of his journey. But the still excitement of the hunt was pumping the blood hotly through his veins. He was now within gunshot, but in that dim light his shooting would be uncertain. He preferred to worm his way nearer, and then trust to his more accustomed weapon, the spear, which he could drive half-way through the tough bulk of a walrus.

At last there remained between him and the seals but one low ridge and then a space of level floe. This was the critical point. If he could writhe his body over the crest and down the other side, he would be within safe spear-shot. He would spring to his feet and throw before the nimblest seal could gain the water. He lay absolutely still, summoning wits, nerves, and muscles alike to serve his will with their best. His eyes burned deep in his head, like smouldering coals.

Just at this moment a ghostly light waved broadly across the solitude. It paled, withdrew, wavered back and forth as shaken from a curtain in the heavens, then steadied ephemerally into an arch of glowing silver, which threw the light of a dozen moons. There were three seals out upon the ice at that moment, and they all lifted their eyes simultaneously to greet the illumination. The man irresistibly looked up; but in the same instant, remembering the hunger in the igloo, he cowered back again out of sight, trembling lest some of the seals might have caught a glimpse of his head above the ridge. Some dozen rods away, at the other side of the air-hole, the great white bear also raised his eyes towards that mysterious light, troubled at heart because he knew it was going to hamper his hunting.

For perhaps two minutes the seals were motionless, profiting by the sudden brightness to scrutinize the expanse of ice and snow in every direction. Then, quite satisfied that no danger was near, they resumed their sportive plungings while the instantly frozen waters crackled crisply about them. For all their vigilance, they had failed to detect, on the one side, a narrow, black-tipped muzzle lying flat in a cleft of the ice-ridge, or, on the other side, a bunch of grayish fur, nearly the color of the grayish-mottled ice, which covered the head of the man from the igloo beside the Little Hills.

And now, while neither the man nor the bear, each utterly unconscious of the other, dared to stir, in a flash the still silver radiance of the aurora broke up and flamed into a riot of dancing color. Parallel rays like the pipes of a Titanic organ, reaching almost from the horizon to the zenith, hurtled madly from side to side, now elongating, now shortening abruptly, now seeming to clash against one another, but always in an ordered madness of right lines. Unearthly green, palpitating into rose, and thinnest sapphire, and flame-color, and ineffably tender violet, the dance of these cohorts of the magnetic rays went on, across the stupendous arc of sky, till the man, afraid of freezing in his unnatural stillness, shrank back down the ridge, and began twisting his body, noiselessly but violently, to set his blood in motion; and the bear, trusting to the confusion of shifting lights, slipped himself over the ridge and into a convenient crevice. Under the full but bewildering glare of that celestial illumination, he had gained a good ten feet upon his human rival. The man’s eyes reappeared just then at the crest of his ridge. Their piercing glance lingered, as if with suspicion, upon the crevice wherein the bear had flattened himself. Was there something unduly solid in that purple shadow in the crevice? No, a trick of the witch lights, surely. The piercing eyes returned to their eager watching of the seals.

Precious as was his ammunition, and indifferent as was his shooting with the old, big bore, Hudson Bay musket, the man was beginning to think he would have to stake his chances on the gun. But, suddenly, as if at a handsweep of the Infinite, the great lights vanished.

For a few seconds, by the violence of the contrast, it seemed as if thick darkness had fallen upon the world.

In those few seconds, noiseless and swift as a panther, the man had run over the ridge to within a dozen paces of the seals, and paused with spear uplifted, waiting till his eyes should once more be able to see in the starlight glimmer. As he stood thus waiting, every sense, nerve, and muscle on the last strain of expectancy and readiness, he heard, or seemed to feel as much as to hear, the rush of some great bulk through the gloom. Then came a scramble, a heavy splash, a second splash, a terrible scuffling noise, and a hoarse, barking scream. The man remembered that before the light went out there had been three seals on the ice. Two he had heard escape. What had befallen the third? Fiercely, like a beast being robbed of its prey, he sprang forward a couple of paces. Then he stopped, for he could not yet see clearly enough to distinguish what was before him. His blood pounded through his veins. The cold of Eternity was flowing in upon him, here on the naked roof of the world, but he had no feeling or fear of it. All he felt was the presence of his foe, there before him, close before him, in the dark.

Then, once more, the light flooded back,—the wide-flung silver radiance,—as suddenly and mysteriously as it had vanished.

Close beside the air-hole, half crouching upon the body of the
