A wolf-dog in the sled pack pricked up his pointed ears, and, straining away from his fellows, sniffed weirdly in the direction of the stricken man. The treacherous huskie leaped savagely against his restraining harness, a low, ominous growl issuing from the ugly curve of his long, trembling jaws. A woolly black-and-tan of the faithful Collie strain gave a snarl of warning; then, with bristles rising on his thick, powerful neck, leaped at the throat of the traitor. That was the signal for a general release of pentup canine irritation. In a trice the whole sled pack was engaged in a furious free-for-all of flying fur and white-flashing fangs.

“Lie down!”

The command came low, deep and vibrant with a faint click of teeth. In electric unison the pack flattened, cowering silent in their places—all but the loyal Collie, which turned with slow-wagging tail and crouching rump to express its fealty as the scrub of the trail parted and a tall youth of spare but powerful build strode into the camp with the carcass of a young buck deer on his shoulder.

The newcomer flung the deer and his rifle to the snow and rushed to the side of the dying man, applying a pocket flask to his lips while he raised him on an arm with the tenderness of a woman. But the elder one was sinking fast—was beyond human aid.

For a few moments he rallied. “Laddie—thank God—you came,” he murmured weakly. “It is the end—the end of the trail—for me. There is so much—so much left undone, Laddie—so much wrong—an erring old man should undo—but you—you, Alexander, my boy—you won’t forget—the mine—the gold mine—goes to—”

The young man bent close to catch the whispered name.

Suddenly the invalid straightened as though galvanised in a last brief lease of life, eyes fixed on some vision above and beyond his companion.

“Black Jack! Black Jack Carlstone!” He cried it as one who cries from the wells of the heart. “Black Jack, my one true friend—you—you will see that the boy—you will see that he carries out my will—”

His torso sagged and his head dropped limply on his chest before he finished.

With reverent touch the young man closed the tired old eyes, while his own welled up and there was a suggestion of a stifled sob in his throat. Mutely for some moments he remained on one knee in the snow, stoically still, looking into the face of the dead man as though questioning the cruel vagaries of Fate.
