were filmed by a growing drowsiness when Wapi drew silently away and slunk suspiciously into the night. There was no yapping foxes here, forty miles from the coast. An almost appalling silence hung under the white stars, a silence broken only by the low and distant moaning the wind always makes on the barrens. Wapi listened to it, and he sniffed with his gray muzzle turned to the north. And then he whined. Had Dolores or Peter seen him or heard the note in his throat, they, too, would have stared back over the trail they had traveled. For something was coming to Wapi. Faint, elusive, and indefinable breath in the air, he smelled it in one moment, and the next it was gone. For many minutes he stood undecided, and then he returned to the sledge, his spine bristling and a growl in his throat.
Wide-eyed and staring, Peter was looking back. "What is it, Wapi?"
His voice aroused Dolores. She sat up with a start. The growl had grown into a snarl in Wapi's throat.
"I think they are coming," said Peter calmly. "You'd better rouse Uppy. He hasn't moved in the last two hours."
Something that was like a sob came from Dolores' lips as she stood up. "They're not coming," she whispered. "They've stopped—and they're building a fire!"
Not more than a third of a mile away a point of yellow flame flared up in the night.
"Give me the revolver, Peter."
Peter gave it to her without a word. She went to Uppy, and at the touch of her foot he was out of his sleeping-bag, his moon-face staring at her. She pointed back to the fire. Her face was dead white. The revolver was pointed straight at Uppy's heart.
"If they come up with us, Uppy—you die!"
The Eskimo's narrow eyes widened. There was murder in this white woman's face, in the steadiness of her hand, and in her voice. If they came up with them—he would die! Swiftly he gathered up his sleeping-bag and placed it on the sledge. Then he roused the dogs, tangled in their traces. They rose to their feet, sleepy and ill-humored. One of them snapped at his hand. Another snarled viciously as he untwisted a trace. Then one of the yawning brutes caught the new smell in the air, the smell that Wapi had gathered when it was a mile farther off. He sniffed. He sat back on his haunches and sent forth a yelping howl to his comrades in the other team. In ten seconds the other five were howling with him, and scarcely had the tumult burst from their throats when there came a response from the fire half a mile away.
"My God!" gasped Peter, under his breath.
Dolores sprang to the gee-bar, and Uppy lashed his long whip until it cracked like a repeating rifle over the pack. The dogs responded and sped through the night. Behind them the pandemonium of dog voices in the other camp had ceased. Men had leaped into life. Fifteen dogs were straightening in the tandem trace of a single sledge.
Dolores laughed, a sobbing, broken laugh, that in itself was a cry of despair. "Peter, if they come up with us, what shall we do?"
"If they overtake us," said Peter, "give me the revolver. It is fully loaded?"
"I have cartridges—"
For the first time she remembered that she had not filled the three empty chambers. Crooking her arm under the gee-bar, she fumbled in her pocket. The dogs, refreshed by their sleep and urged by Uppy's whip, were tearing off the first mile at a great speed. The trail ahead of them was level and hard again. Uppy knew they were on the edge of the big barren of the Lacs Delesse, and he cracked his whip just as the off runner of the sledge struck a hidden snow-blister. There was a sudden lurch, and in a vicious up-shoot of the gee-bar the revolver was knocked from Dolores' hand—and was gone. A shriek rose to her lips, but she stifled it before it was given voice. Until this minute she had not felt the terror of utter hopelessness upon her. Now it made her faint. The revolver had not only given her hope, but also a steadfast faith in herself. From the beginning she had made up her mind how she would use it in the end, even though a few moments before she had asked Peter what they would do.
Crumpled down on the sledge, she clung to Peter, and suddenly the inspiration came to her not to let him know what had happened. Her arms tightened about his shoulders, and she looked ahead over the backs of the wolfish pack, shivering as she thought of what Uppy would do could he guess her loss. But he was running now for his life, driven on by his fear of her unerring marksmanship—and Wapi. She looked over her shoulder. Wapi was there, a huge gray shadow twenty paces behind. And she thought she heard a shout!
Peter was speaking to her. "Blake's dogs are tired," he was saying. "They were just about to camp, and ours have had a rest. Perhaps—"
"We shall beat them!" she interrupted him. "See how fast we are going, Peter! It is splendid!"
A rifle-shot sounded behind them. It was not far away, and involuntarily she clutched him tighter. Peter reached up a hand.
"Give me the revolver, Dolores."
"No," she protested. "They are not going to overtake us."
"You must give me the revolver," he insisted.
"Peter, I can't. You understand, I can't. I must keep the revolver."
She looked back again. There was no doubt now. Their pursuers were drawing nearer. She heard a voice, the la-looing of running Eskimos, a faint shout which she knew was a white man's shout—and another rifle shot. Wapi was running nearer. He was almost at the tail of the sledge, and his red eyes were fixed on her as he ran.
"Wapi!" she cried. "Wapi!"
His jaws dropped agape. She could hear his panting response to her voice.
A third shot—over their heads sped a strange droning sound.
"Wapi," she almost screamed, "go back! Sick 'em, Wapi—sick 'em—sick 'em—sick 'em!" She flung out her arms, driving him back, repeating the words over and over again. She leaned over the edge of the sledge, clinging to the gee-bar. "Go back, Wapi! Sick 'em—sick 'em—sick 'em!"
As if in response to her wild exhortation, there came a sudden yelping outcry from the team behind. It was close upon them now. Another ten minutes.
And then she saw that Wapi was dropping behind. Quickly he was swallowed up in the starlit chaos of the night.
"Peter," she cried, sobbingly. "Peter!"
Listening to the retreating sound of the sledge, Wapi stood a silent shadow in the trail. Then he turned and faced the north. He heard the other sound now, and ahead of it the wind brought him a smell, the smell of things he hated. For many years something had been fighting itself toward understanding within him, and the yelping of dogs and the taint in the air of creatures who had been his slave-masters narrowed his instinct to the one vital point. Again it was not a process of reason but the cumulative effect of things that had happened, and were happening. He had scented menace when first he had given warning of the nearness of pursuers, and this menace was no longer an elusive and unseizable thing that had merely stirred the fires of his hatred. It was now a near and physical fact. He had tried to run away from it—with the woman—but it had followed and was overtaking him, and the yelping dogs were challenging him to fight as they had challenged him from the day he was old enough to take his own part. And now he had something to fight for. His intelligence gripped the fact that one sledge was running away from the other, and that the sledge which was running away was his sledge—and that for his sledge he must fight.
He waited, almost squarely in the trail. There was no longer the slinking, club-driven attitude of a creature at bay in the manner in which he stood in the path of his enemies. He had risen out of his serfdom. The stinging slash of the whip and his dread of it were gone. Standing there in the starlight with his magnificent head thrown up and the muscles of his huge body like corded steel, the passing spirit of Shan Tung would have taken him for Tao, the Great Dane. He was not excited—and yet he was filled with a mighty desire—more than that, a tremendous purpose. The yelping excitement of the oncoming Eskimo dogs no longer urged him to turn aside to avoid their insolent bluster, as he would have turned aside yesterday or the day before. The voices of his old masters no longer sent him slinking out of their way, a growl in his throat and his
