Things went well with him for the first few days, and although the trail was now lost, he guided himself easily by the stars, of which he had been careful to take note and make comparison with the hand in the letter before disturbing its position. But one night the sky became overcast, and he would have been compelled to halt had he not previously laid his course by several huge icebergs which towered up in the far distance.

When he had passed the last of these bergs, however, he began to hesitate in his movements, and Attim, trotting quietly by his side, looked inquiringly up into his face once or twice with the obvious question, “What’s the matter?” in his soft brown eyes—or some Dogrib idiom equivalent thereto.

“I’m afraid to go on,” murmured the Indian gravely.

To this Attim replied with a reassuring wag of his tail.

“Without stars it won’t be easy to keep the straight line,” continued the chief, stopping altogether and looking up at the clouds.

Attim also looked up, but evidently could make nothing of it, for he turned his eyes again on his master and wagged his tail dubiously.

At the moment a rift in the clouds revealed some of the stars, and the Indian, regaining his direction again, hurried forward—all the more rapidly that a pretty stiff fair wind was blowing, to speak nautically, right astern of him.

By degrees the breeze increased to a gale, and then to a regular hurricane, which whirled among the bergs and hummocks, shrieked round the ice-pinnacles, and went howling over the plain of the solid sea as if all the Hyperborean fiends had been let loose and told to do their worst. Its violence was so great that the Indian was forced to scud before it, and more than once Attim’s little bundle caught the blast and whirled him round like a weathercock, while the drifting snow at last became so thick that it was impossible to see anything more than a few yards ahead. In these circumstances to advance was madness.

“It won’t do, pup,” cried Nazinred, turning suddenly to his right round a mass of ice, and taking shelter in the lee of a towering berg; “come, we will encamp here.”

He had scarcely uttered the words when a tremendous rending sound was heard above the noise of the hurricane. The Indian looked up quickly, but nothing was to be seen anywhere save that wild confusion of whirling snow, which in more southerly lands is sometimes called a blizzard, and the back-whirl of which nearly suffocated man and dog. Suddenly there came a crash as if a mountain were being shattered near them. Then Nazinred saw, to his horror, that an ice-pinnacle as big as a church steeple was bowing forward, like some mighty giant, to its fall. To escape he saw was impossible. It was too near and too directly above his head for that. His only hope lay in crushing close to the side of the berg. He did so, on the instant, promptly followed by the dog, and happily found that the ice-wall at the spot was slightly concave.
