The match flared out in Ben's fingers, and the only light that was left was the pale moonlight, like a cobweb on the floor of the glade, and the faint glow from the dying fire. About the glade ranged the tall spruce, Watching breathlessly; and for a termless second or two a profound and portentous silence descended on the camp. No leaf rustled, not a tree limb cracked. The creature that had pushed through the thickets to the edge of the glade was evidently standing motionless, deciding on his course.

Only the wild things seem to know what complete absence of motion means. To stand like a form in rock, not a muscle quivering or a hair stirring, is never a feat for ragged, over stretched human nerves; and it requires a perfect muscle control that is generally only known to the beasts of the forest. Only a few times in a lifetime in human beings are the little, outward motions actually suspended; perhaps under the paralysis of great terror or, with painstaking effort, before a photographer's camera. But with the beasts it is an everyday accomplishment necessary to their survival. The fawn that can not stand absolutely motionless, his dappled skin blending perfectly with the background of shrubbery shot with sunlight, comes to an end quickly in the fangs of some great beast of prey. The panther that can not lurk, not a muscle quivering, in his ambush beside the deer trail, never knows full feeding. The creature on the opposite side of the glade seemed as bereft of motion as the spruce trees in the moonlight, or the cliff above the cave.

"What is it?" Beatrice whispered. The man's eyes strained into the gloom.

"I don't know. It may be just a moose, or maybe a caribou. But it may be—"

He tiptoed to the door of the cave, and his eye fell to the crouching form of Fenris. The creature outside was neither moose nor caribou. The great wolf of the North does not stand at bay to the antlered people. He was poised to spring, his fangs bared and his fierce eyes hot with fire, but he was not hunting. Whatever moved in the darkness without, the wolf had no desire to go forth and attack. Perhaps he would fight to the death to protect the occupants of the cave; but surely an ancient and devastating fear had hold of him. Evidently he recognized the intruder as an ancestral enemy that held sovereignty over the forest.

At that instant Ben leaped through the cavern maw to reach his gun. There was nothing to be gained by waiting further. This was a savage and an uninhabited land; and the great beasts of prey that ranged the forest had not yet learned the restraint born of the fear of man. And he knew one breathless instant of panic when his eye failed to locate the weapon in the faint light of the fire.

Holding hard, he tried to remember where he had left it. The form across the glade was no longer motionless. Straining, Ben saw the soft roll of a great shadow, almost imperceptible in the gloom—advancing slowly toward him. Then the faint glow of the fire caught and reflected in the creature's eyes.

They suddenly glowed out in the half-darkness, two rather small circles of dark red, close together and just alike. This night visitor was not moose or caribou, or was it one of the lesser hunters, lynx or wolverine, or a panther wandered far from his accustomed haunts. The twin circles were too far above the ground. And whatever it was, no doubt remained but that the creature was steadily stalking him across the soft grass.

At that instant Ben's muscles snapped into action. Only a second remained in which to make his defense—the creature had paused, setting his muscles for a death-dealing charge. "Go back into the cave—as far as you can," he said swiftly to Beatrice. His own eyes, squinted and straining for the last iota of vision in that darkened scene, made a last, frantic search for his rifle. Suddenly he saw the gleam of its barrel as it rested against the wall of the cliff, fifteen feet distant.

At once he knew that his only course was to spring for it in the instant that remained, and trust to its mighty shocking power to stop the charge that would in a moment ensue. Yet it seemed to tear the life fiber of the man to do it. His inmost instincts, urgent and loud in his ear, told him to remain on guard, not to leave that cavern maw for an instant but to protect with his own body the precious life that it sheltered. His mind worked with that incredible speed that is usually manifest in a crisis; and he knew that the creature might charge into the cavern entrance in the second that he left it. Yet only in the rifle lay the least chance or hope for either of them.
