For perhaps the first time in his life Howland felt the spirit of romance, of adventure, of sympathy for the picturesque and the unknown surging through his veins. A billion stars glowed like yellow, passionless eyes in the polar cold of the skies. Behind him, white in its sinuous twisting through the snow-smothered wilderness, lay the icy Saskatchewan, with a few scattered lights visible where Prince Albert, the last outpost of civilization, came down to the river half a mile away. But it was into the North that Howland looked. From the top of the great ridge which he had climbed he gazed steadily into the white gloom which reached for a thousand miles from where he stood to the Arctic Sea. Faintly in the grim silence of the winter night there came to his ears the soft hissing sound of the aurora borealis as it played in its age-old song over the dome of the earth, and as he watched the cold flashes shooting like pale arrows through the distant sky and listened to its whispering music of unending loneliness and mystery, there came on him a strange feeling that it was beckoning to him and calling to him - telling him that up there very near to the end of the earth lay all that he had dreamed of and hoped for since he had grown old enough to begin the shaping of a destiny of his own.
