When at last he answered it was in a tone of fiery abruptness.

“Guess not,” he said. And it was Ralph’s turn to hold back the anger which rose within him.

“Why?”

“Say, brother,” said Nick, with a biting distinctness, “quit right there. Ther’ ain’t no need fer another word.”

For a moment Ralph peered into the other’s face; but he remained silent. Then he turned over upon his pillow with a sound very like a muttered curse. And from that moment the gulf between them became impassable. Aim-sa was a subject henceforth tabooed from their conversation. Each watched the other with distrust, and even hatred, full grown within him.

And soon there came a further disturbing element in that mountain home. It awoke all the dormant atmosphere of mystery, which, in the minds of the two men, surrounded the lovely Aim-sa. It awoke afresh the “Dread of the Wild” that had assailed them on their journey north.

It came in the early morning, when the world about them was cloaked in the grey shroud of daylight mists; when the silent forests above and below them were rendered even more ghostly and sepulchral by reason of the heavy vapour which depressed all on which it settled. Nick was standing, rifle in hand, preparing to sling it across his back. Ralph was stooping to adjust his snow-shoes. Aim-sa had been left within the hut.

A gentle breeze, like the icy breath of some frozen giant on the peak above the hut, came lazily down the hillside. It broke the fog into a turmoil of protest. The heavy vapour rolled in huge waves, sought to return to its settled calm, then slowly lifted from the flustered tree-tops. Another breath, a little stronger than the first, shot forcefully into the heart of the morning fog and scattered it mercilessly. Then the whole grey expanse solemnly lifted. Up it rose; nor did it pause until the lower hills were bared, and the wintry sun shone splendidly down upon the crystal earth.

And as the air cleared the keen eyes of Nick flashed out in a swift survey of the prospect. Suddenly his breathing was sharply indrawn. His rifle never reached his shoulder, but remained gripped in his hand. His eyes had become riveted upon a low hill far out across the valley. It looked as though it rose sheer out of the forest below, but the watching man knew full well that it was only a spur of the giant that backed it. It was the summit of this clear-cut hill, and what was visible upon it, that held his fascinated attention. Suddenly a half-whispered word escaped him and Ralph was beside him in a moment.

“Look!” And Nick’s arm was outstretched pointing.
