In Dr. Hayes’ account of his voyage of discovery towards the North Pole occurs a fine passage descriptive of the various phases of the Arctic night. “I have gone out often,” he says, “into its darkness, and viewed Nature under different aspects. I have rejoiced with her in her strength, and communed with her in her repose. I have seen the wild burst of her anger, have watched her sportive play, and have beheld her robed in silence. I have walked abroad in the darkness when the winds were roaring through the hills and crashing over the plain. I have strolled along the beach when the only sound that broke the stillness was the dull creaking of the ice-floes, as they rose and fell lazily with the tide. I have wandered far out upon the frozen sea, and listened to the voice of the icebergs bewailing their imprisonment; along the glacier, where forms and falls the avalanche; upon the hill-top, where the drifting snow, coursing over the rocks, sung its plaintive song; and again, I have wandered away to some distant valley where all these sounds were hushed, and the air was still and solemn as the tomb.” Whoever has been overtaken by a winter night, when crossing some snowy plain, or making his way over the hills and through the valleys, in the deep drifts, and with the icicles pendent from the leafless boughs, and the white mantle overspreading every object dimly discernible in the darkness, will have felt the awe and mystery of the _silence_ that then and there prevails. Both the sky above and the earth beneath reveal only an endless and unfathomable quiet. This, too, is the peculiar characteristic of the Arctic night. Evidence there is none of life or motion. No footfall of living thing breaks on the longing ear. No cry of bird enlivens the scene; there is no tree, among the branches of which the wind may sigh and moan. And hence it is that one who had travelled much, and seen many dangers, and witnessed Nature in many phases, was led to say that he had seen no expression on the face of Nature so filled with terror as the silence of the Arctic night.
