McDougall's ten malamutes were the pride of McDougall and the envy of the Yukon. As they disappeared in the distance bearing Connie Morgan on the trail of his deserting "pardner," the big Scotchman turned and entered his cabin.

"He's a braw lad," he rumbled, as he busied himself about the stove. "To Waseche's mind the lad's but a wee lad; an' the mon done what few men w'd done when ut come to the test. But, fer a' his sma' size the lad's uncanny knowin', an' the heart o' um's the heart o' a tillicum.

"He'll fetch Waseche back, fer he'll tak' na odds—an' a gude job ut'll be—fer, betwixt me an' mesel', the ain needs the ither as much as the ither needs the ain. 'Tis the talk o' the camp that ne'er a nicht sin' Ten Bow started has Waseche darkened the door o' Dog Head Jake's saloon, an' they aint a sourdough along the Yukon but what kens when things was different wi' Waseche Bill."

Out on the trail, Connie urged the dogs forward. Like Waseche Bill, he, too, had learned to love the great White Country, but this day he had eyes only for the long sweep of the trail and the flying feet of the malamutes.

"I must catch him! I've got to catch him!" he kept repeating to himself, as the flying sled shot along hillsides and through long stretches of stunted timber. "He'll make Ragged Falls Post tonight, and I'll make it before morning."

Darkness had fallen before the long team swept out onto the Yukon. Overhead the stars winked coldly upon the broad surface of the frozen river whose snow reefs and drifts, between which wound the trail, lay like the marble waves of a sculptured ocean.

Old Boris, running free in the lead, paused at the junction of the trails, sniffed at the place where Waseche had halted early in the morning, and loped unhesitatingly up the river. The old lead dog was several hundred yards in advance of the team, and cut off from sight by the high-piled drifts; so that when Connie reached the spot he swung the malamutes downstream in the direction of Ragged Falls Post, never for an instant suspecting that his partner had taken the opposite trail.

For several minutes old Boris ran on with his nose to the snow, then, missing the sound of the scratching feet and the dry husk of the runners, he paused and listened with ears cocked and eyes in close scrutiny of the back trail. Surely, those were the sounds of the dog team—but why were they growing fainter in the distance? The old dog whimpered uneasily, and then, throwing back his head, gave voice to a long, bell-like cry which, floating out on the tingling air like the blast of a bugle, was borne to the ears of the boy on the flying dog sled, already a half-mile to the westward. At his sharp command, the well trained malamutes nearly piled up with the suddenness of their stop. The boy listened breathlessly and again it sounded—the long-drawn howl he knew so well. "Why has Boris left the trail," wondered the boy. "Had Waseche met with an accident and camped? Were the feet of his dogs sore? Was he hurt?" Connie glanced at his own two dogs, Mutt and Slasher, who, unharnessed, had followed in his wake. They, too, heard the call of their leader and had crouched in the snow, gazing backward. Quickly he swung the sled dogs and dashed back at a gallop. Passing the point where the Ten Bow trail slanted into the hills, he urged the dogs to greater effort. If something had happened and Waseche had camped, the quicker he found him the better. But, if Waseche had not camped, and old Boris was fooling him, it would mean nearly an hour lost in useless doubling. With anxious eyes he scanned the trail ahead, seeking to penetrate the gloom of the Arctic night. At length, as the sled shot from between two high-piled drifts, he made out a dark blotch in the distance, which quickly resolved itself into the figure of the old lead dog sitting upon his haunches with ears alert for the approaching sled. Connie whistled, a loud, peculiar whistle, and the old dog bounded forward with short, quick yelps of delight.

"Where is Waseche, Boris?" The boy had leaped from the sled and was mauling the rough coat playfully. "Find Waseche! Boris! Go find him!" With a sharp, joyful bark, the old dog leaped out upon the trail and the wolf-dogs followed. A mile slipped past—two miles—and no sign of Waseche! The boy called a halt. "Boris is fooling me," he muttered, with disappointment. "He couldn't have come this far and gotten back to the place I found him."
