up with the dense pall from the south and west. The distant rumbling of thunder grew louder, and she huddled herself again under the tree. For hours the storm crashed over her, and the rain fell in a deluge. When it had finished she slunk out from her shelter like a thing beaten. Vainly she sought for one last scent of Kazan. The club was washed clean. Again the sand was white where Kazan's blood had reddened it. Even under the tree there was no sign of him left.
Until now only the terror of being alone in the pit of darkness that enveloped her had oppressed Gray Wolf. With afternoon came hunger. It was this hunger that drew her from the sand-bar, and she wandered back into the plain. A dozen times she scented game, and each time it evaded her. Even a ground-mouse that she cornered under a root, and dug out with her paws, escaped her fangs.
Thirty-six hours before this Kazan and Gray Wolf had left a half of their last kill a mile of two farther back on the plain. The kill was one of the big barren rabbits, and Gray Wolf turned in its direction. She did not require sight to find it. In her was developed to its finest point that sixth sense of the animal kingdom, the sense of orientation, and as straight as a pigeon might have winged its flight she cut through the bush to the spot where they had cached the rabbit. A white fox had been there ahead of her, and she found only scattered bits of hair and fur. What the fox had left the moose-birds and bush-jays had carried away. Hungrily Gray Wolf turned back to the river.
That night she slept again where Kazan had lain, and three times she called for him without answer. A heavy dew fell, and it drenched the last vestige of her mate's scent out of the sand. But still through the day that followed, and the day that followed that, blind Gray Wolf clung to the narrow rim of white sand. On the fourth day her hunger reached a point where she gnawed the bark from willow bushes. It was on this day that she made a discovery. She was drinking, when her sensitive nose touched something in the water's edge that was smooth, and bore a faint odor of flesh. It was one of the big northern river clams. She pawed it ashore, sniffing at the hard shell. Then she crunched it between her teeth. She had never tasted sweeter meat than that which she found inside, and she began hunting for other clams. She found many of them, and ate until she was no longer hungry. For three days more she remained on the bar.
And then, one night, the call came to her. It set her quivering with a strange new excitement—something that may have been a new hope, and in the moonlight she trotted nervously up and down the shining strip of sand, facing now the north, and now the south, and then the east and the west—her head flung up, listening, as if in the soft wind of the night she was trying to locate the whispering lure of a wonderful voice. And whatever it was that came to her came from out of the south and east. Off there—across the barren, far beyond the outer edge of the northern timber-line—was home. And off there, in her brute way, she reasoned that she must find Kazan. The call did not come from their old windfall home in the swamp. It came from beyond that, and in a flashing vision there rose through her blindness a picture of the towering Sun Rock, of the winding trail that led to it, and the cabin on the plain. It was there that blindness had come to her. It was there that day had ended, and eternal night had begun. And it was there that she had mothered her first-born. Nature had registered these things so that they could never be wiped out of her memory, and when the call came it was from the sunlit world where she had last known light and life and had last seen the moon and the stars in the blue night of the skies.
And to that call she responded, leaving the river and its food behind her—straight out into the face of darkness and starvation, no longer fearing death or the emptiness of the world she could not see; for ahead of her, two hundred miles away, she could see the Sun Rock, the winding trail, the nest of her first-born between the two big rocks—and Kazan!
CHAPTER XXV
THE LAST OF MCTRIGGER
Sixty miles farther north Kazan lay at the end of his fine steel chain, watching little Professor McGill mixing a pail of tallow and bran. A dozen yards from him lay the big Dane, his huge jaws drooling in anticipation of the unusual feast which McGill was preparing. He showed signs of pleasure when McGill approached him with a quart of the mixture, and he gulped it between his huge jaws. The little man with the cold blue eyes and the gray-blond hair stroked his back without fear. His attitude was different when he turned to Kazan. His movements were filled with caution, and yet his eyes and his lips were smiling, and he gave the wolf-dog no evidence of his fear, if it could be called fear.
The little professor, who was up in the north country for the Smithsonian Institution, had spent a third of his life among dogs. He loved them, and understood them. He had written a number of magazine articles on dog intellect that had attracted wide attention among naturalists. It was largely because he loved dogs, and understood them more than most men, that he had bought Kazan and the big Dane on the night when Sandy McTrigger and his partner had tried to get them to fight to the death in the Red Gold City saloon. The refusal of the two splendid beasts to kill each other for the pleasure of the three hundred men who had assembled to witness the fight delighted him. He had already planned a paper on the incident. Sandy had told him the story of Kazan's capture, and of his wild mate, Gray Wolf, and the professor had asked him a thousand questions. But each day Kazan puzzled him more. No amount of kindness on his part could bring a responsive gleam in Kazan's eyes. Not once did Kazan signify a willingness to become friends. And yet he did not snarl at McGill, or snap at his hands when they came within reach. Quite frequently Sandy McTrigger came over to the little cabin where McGill was staying, and three times Kazan leaped at the end of his chain to get at him, and his white fangs gleamed as long as Sandy was in sight. Alone with McGill he became quiet. Something told him that McGill had come as a friend that night when he and the big Dane stood shoulder to shoulder in the cage that had been built for a slaughter pen. Away down in his brute heart he held McGill apart from other men. He had no desire to harm him. He tolerated him, but showed none of the growing affection of the huge Dane. It was this fact that puzzled McGill. He had never before known a dog that he could not make love him.
To-day he placed the tallow and bran before Kazan, and the smile in his face gave way to a look of perplexity. Kazan's lips had drawn suddenly back. A fierce snarl rolled deep in his throat. The hair along his spine stood up. His muscles twitched. Instinctively the professor turned. Sandy McTrigger had come up quietly behind him. His brutal face wore a grin as he looked at Kazan.
"It's a fool job—tryin' to make friends with him" he said. Then he added, with a sudden interested gleam in his eyes, "When you startin'?"
"With first frost," replied McGill. "It ought to come soon. I'm going to join Sergeant Conroy and his party at Fond du Lac by the first of October."
"And you're going up to Fond du Lac—alone?" queried Sandy. "Why don't you take a man?"
The little professor laughed softly.
"Why?" he asked. "I've been through the Athabasca waterways a dozen times, and know the trail as well as I know Broadway. Besides, I like to be alone. And the work isn't too hard, with the currents all flowing to the north and east."
Sandy was looking at the Dane, with his back to McGill. An exultant gleam shot for an instant into his eyes.
"You're taking the dogs?"
"Yes."
Sandy lighted his pipe, and spoke like one strangely curious.
"Must cost a heap to take these trips o' yourn, don't it?"
"My last cost about seven thousand dollars. This will cost five," said McGill.
"Gawd!" breathed Sandy. "An' you carry all that along with you! Ain't you afraid—something
