A second flash—­and the death-bee drove from breast to tail of a huge gray fighter close to Gray Wolf.  A third—­a fourth—­a fifth spurt of that fire from the black shadow, and Kazan himself felt a sudden swift passing of a red-hot thing along his shoulder, where the man’s last bullet shaved off the hair and stung his flesh.

Three of the pack had gone down under the fire of the rifle, and half of the others were swinging to the right and the left.  But Kazan drove straight ahead.  Faithfully Gray Wolf followed him.

The sledge-dogs had been freed from their traces, and before he could reach the man, whom he saw with his rifle held like a club in his hands, Kazan was met by the fighting mass of them.  He fought like a fiend, and there was the strength and the fierceness of two mates in the mad gnashing of Gray Wolf’s fangs.  Two of the wolves rushed in, and Kazan heard the terrific, back-breaking thud of the rifle.  To him it was the club.  He wanted to reach it.  He wanted to reach the man who held it, and he freed himself from the fighting mass of the dogs and sprang to the sledge.  For the first time he saw that there was something human on the sledge, and in an instant he was upon it.  He buried his jaws deep.  They sank in something soft and hairy, and he opened them for another lunge.  And then he heard the voice!  It was her voice!  Every muscle in his body stood still.  He became suddenly like flesh turned to lifeless stone.

Her voice!  The bear rug was thrown back and what had been hidden under it he saw clearly now in the light of the moon and the stars.  In him instinct worked more swiftly than human brain could have given birth to reason.  It was not she.  But the voice was the same, and the white girlish face so close to his own blood-reddened eyes held in it that same mystery that he had learned to love.  And he saw now that which she was clutching to her breast, and there came from it a strange thrilling cry—­and he knew that here on the sledge he had found not enmity and death, but that from which he had been driven away in the other world beyond the ridge.

In a flash he turned.  He snapped at Gray Wolf’s flank, and she dropped away with a startled yelp.  It had all happened in a moment, but the man was almost down.  Kazan leaped under his clubbed rifle and drove into the face of what was left of the pack.  His fangs cut like knives.  If he had fought like a demon against the dogs, he fought like ten demons now, and the man—­bleeding and ready to fall—­staggered back to the sledge, marveling at what was happening.  For in Gray Wolf there was now the instinct of matehood, and seeing Kazan tearing and righting the pack she joined him in the struggle which she could not understand.

When it was over, Kazan and Gray Wolf were alone out on the plain.  The pack had slunk away into the night, and the same moon and stars that had given to Kazan the first knowledge of his birthright told him now that no longer would those wild brothers of the plains respond to his call when he howled into the sky.
