For a long time Kazan and Gray Wolf did not move, and when at last they returned to the beaten trail the bull's heavy head was resting on the snow. Again they began to circle, and now the circle narrowed foot by foot, until only ten yards—then nine—then eight—separated them from their prey. The bull attempted to rise, and failed. Gray Wolf heard the effort. She heard him sink back and suddenly she leaped in swiftly and silently from behind. Her sharp fangs buried themselves in the bull's nostrils, and with the first instinct of the husky, Kazan sprang for a throat hold. This time he was not flung off. It was Gray Wolf's terrible hold that gave him time to tear through the half-inch hide, and to bury his teeth deeper and deeper, until at last they reached the jugular. A gush of warm blood spurted into his face. But he did not let go. Just as he had held to the jugular of his first buck on that moonlight night a long time ago, so he held to the old bull now. It was Gray Wolf who unclamped his jaws. She drew back, sniffing the air, listening. Then, slowly, she raised her head, and through the frozen and starving wilderness there went her wailing triumphant cry—the call to meat.

For them the days of famine had passed.

Chapter XIV

The Right Of Fang

After the fight Kazan lay down exhausted in the blood-stained snow, while faithful Gray Wolf, still filled with the endurance of her wild wolf breed, tore fiercely at the thick skin on the bull's neck to lay open the red flesh. When she had done this she did not eat, but ran to Kazan's side and whined softly as she muzzled him with her nose. After that they feasted, crouching side by side at the bull's neck and tearing at the warm sweet flesh.

The last pale light of the northern day was fading swiftly into night when they drew back, gorged until there were no longer hollows in their sides. The faint wind died away. The clouds that had hung in the sky during the day drifted eastward, and the moon shone brilliant and clear. For an hour the night continued to grow lighter. To the brilliance of the moon and the stars there was added now the pale fires of the aurora borealis, shivering and flashing over the Pole.

Its hissing crackling monotone, like the creaking of steel sledge-runners on frost-filled snow, came faintly to the ears of Kazan and Gray Wolf.

As yet they had not gone a hundred yards from the dead bull, and at the first sound of that strange mystery in the northern skies they stopped and listened to it, alert and suspicious. Then they laid their ears aslant and trotted slowly back to the meat they had killed. Instinct told them that it was theirs only by right of fang. They had fought to kill it. And it was in the law of the wild that they would have to fight to keep it. In good hunting days they would have gone on and wandered under the moon and the stars. But long days and nights of starvation had taught them something different now.

On that clear and stormless night following the days of plague and famine, a hundred thousand hungry creatures came out from their retreats to hunt for food. For eighteen hundred miles east and west and a thousand miles north and south, slim gaunt-bellied creatures hunted under the moon and the stars. Something told Kazan and Gray Wolf that this hunt was on, and never for an instant did they cease their vigilance. At last they lay down at the edge of the spruce thicket, and waited. Gray Wolf muzzled Kazan gently with her blind face. The uneasy whine in her throat was a warning to him. Then she sniffed the air, and listened—sniffed and listened.
