The primal instincts come uppermost at such times, and like the wild creatures of the woods facing a foe, instantaneously we wheeled back to back, alert for the enemy that had frightened the caribou.

"Hist!" whispers Radisson. "Look!"

Ben Gillam leaped into the air as if he had been shot, shrieking out: "It's him! It's him! Shoot him! The thief! The traitor! It's him!"

He dashed forward, followed by the rest of us, hardly sure whether Ben were sane.

Three figures loomed through the snowy darkness, white and silent as the snow itself—vague as phantoms in mist—pointing at us like wraiths of death—spirit hunters incarnate of that vast wilderness riding the riotous storm over land and sea. One swung a weapon aloft. There was the scream as of a woman's cry—and the shrieking wind had swept the snow-clouds about us in a blind fury that blotted all sight. And when the combing billows of drift passed, the apparition had faded. We four stood alone staring in space with strange questionings.

"Egad!" gasped Radisson, "I don't mind when the wind howls like a wolf, but when it takes to the death-scream, with snow like the skirts of a shroud——"

"May the Lord have mercy on us!" muttered La Chesnaye, crossing himself. "It is sign of death! That was a woman's figure. It is sign of death!"

"Sign of death!" raged Ben, stamping his impotent fury, "'tis him—'tis him! The Judas Iscariot, and he's left us to die so that he may steal the furs!"

"Hold quiet!" ordered M. Radisson. "Look, you rantipole—who is that?"

'Twas Le Borgne, the one-eyed, emerging from the gloom of the snow like a ghost. By signs and Indian words the fellow offered to guide us back to our Habitation.
