Confidence without making every effort in their power to stop them. Once they succeeded in placing certain facts in the hands of the Mounted Police, both Rydal and Blake would be done for. He impressed this uncomfortable truth on Dolores and suggested that if she could have smuggled a rifle along in the dunnage sack it would have helped matters considerably. For Rydal and Blake would not hesitate at shooting. For them it must be either capture or kill—death for him, anyway, for he was the one factor not wanted in the equation. He summed up their chances and their danger calmly and pointedly, as he always looked at troubling things. And Dolores felt her heart sinking within her. After all, she had not handled the situation any too well. She almost wished she had killed Rydal herself and called it self-defense. At least she had been criminally negligent in not smuggling along a rifle.

"But we'll beat them out," she argued hopefully. "We've got a splendid team, Peter, and I'll take off my coat and run behind the sledge as much as I can. Uppy won't dare play a trick on us now, for he knows that if I should miss him, Wapi would tear the life out of him at a word from me. We'll win out, Peter dear. See if we don't!"

Peter hugged his thoughts to himself. He did not tell her that Blake and Rydal would pursue with a ten- or twelve-dog team, and that there was almost no chance at all of a straight get-away. Instead, he pulled her head down and kissed her.

To Wapi there had come at last a response to the great yearning that was in him. Instinct, summer and winter, had drawn him south, had turned him always in that direction, filled with the uneasiness of the mysterious something that was calling to him through the years of forty generations of his kind. And now he was going south. He sensed the fact that this journey would not end at the edge of the Arctic plain and that he was not to hunt caribou or bear. His mental formulae necessitated no process of reasoning. They were simple and to the point His world had suddenly divided itself into two parts; one contained the woman, and the other his old masters and slavery. And the woman stood against these masters. They were her enemies as well as his own. Experience had taught him the power and the significance of firearms, just as it had made him understand the uses for which spears, and harpoons, and whips were made. He had seen the woman shoot Blake, and he had seen her ready to shoot at Uppy. Therefore he understood that they were enemies and that all associated with them were enemies. At a word from her he was ready to spring ahead and tear the life out of the Eskimo driver and even out of the dogs that were pulling the sledge. It did not take him long to comprehend that the man on the sledge was a part of the woman.

He hung well back, twenty or thirty paces behind the sledge, and unless Peter or the woman called to him, or the sledge stopped for some reason, he seldom came nearer.

It took only a word from Dolores to bring him to her side.

Hour after hour the journey continued. The plain was level as a floor, and at intervals Dolores would run in the trail that the load might be lightened and the dogs might make better time. It was then that Peter watched Uppy with the revolver, and it was also in these intervals—running close beside the woman—that the blood in Wapi's veins was fired with a riotous joy.

For three hours there was almost no slackening in Uppy's speed. The fourth and fifth were slower. In the sixth and seventh the pace began to tell. And the plain was no longer hard and level, swept like a floor by the polar winds. Rolling undulations grew into ridges of snow and ice; in places the dogs dragged the sledge over thin crusts that broke under the runners; fields of drift snow, fine as shot, lay in their way; and in the eighth hour Uppy stopped the lagging dogs and held up his two hands in the mute signal of the Eskimo that they could go no farther without a rest.

Wapi dropped on his belly and watched. His eyes followed Uppy suspiciously as he strung up the tent on its whalebone supports to keep the bite of the wind from the sledge on which Dolores sat at Peter's feet. Then Uppy built a fire of kindlings, and scraped up a pot of ice for tea-water. After that, while the water was heating, he gave each of the trace dogs a frozen fish. Dolores herself picked out one of the largest and tossed it to Wapi. Then she sat down again and began to talk to Peter, bundled up in his furs. After a time they ate, and drank hot tea, and after he had devoured a chunk of raw meat the size of his two fists, Uppy rolled himself in his sleeping bag near the dogs. A little at a time Wapi dragged himself nearer until his head lay on Dolores' coat. After that there was a long silence broken only by the low voices of the woman and the man, and the heavy breathing of the tired dogs. Wapi himself dozed off, but never for long. Then Dolores nodded, and her head drooped until it found a pillow on Peter's shoulder. Gently Peter drew a bearskin about her, and for a long time sat wide-awake, guarding Uppy and baring his ears at intervals to listen. A dozen times he saw Wapi's bloodshot eyes looking at him, and twice he put out a hand to the dog's head and spoke to him in a whisper.

Even Peter's eyes 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
