When I at length settled down to my books again and tried to read, I became aware, for the first time, that the room seemed growing cold. Yet the day had been oppressively warm, and evening had brought no relief. The six big lamps, moreover, gave out heat enough to warm the room pleasantly. But a chilliness, that perhaps crept up from the lake, made itself felt in the room, and caused me to get up to close the glass door opening on to the verandah. For a brief moment I stood looking out at the shaft of light that fell from the windows and shone some little distance down the pathway, and out for a few feet into the lake. As I looked, I saw a canoe glide into the pathway of light, and immediately crossing it, pass out of sight again into the darkness. It was perhaps a hundred feet from the shore, and it moved swiftly. I was surprised that a canoe should pass the island at that time of night, for all the summer visitors from the other side of the lake had gone home weeks before, and the island was a long way out of any line of water traffic. My reading from this moment did not make very good progress, for somehow the picture of that canoe, gliding so dimly and swiftly across the narrow track of light on the black waters, silhouetted itself against the background of my mind with singular vividness. It kept coming between my eyes and the printed page. The more I thought about it the more surprised I became. It was of larger build than any I had seen during the past summer months, and was more like the old Indian war canoes with the high curving bows and stern and wide beam. The more I tried to read, the less success attended my efforts; and finally I closed my books and went out on the verandah to walk up and down a bit, and shake the chilliness out of my bones. The night was perfectly still, and as dark as imaginable. I stumbled down the path to the little landing wharf, where the water made the very faintest of gurgling under the timbers. The sound of a big tree falling in the mainland forest, far across the lake, stirred echoes in the heavy air, like the first guns of a distant night attack. No other sound disturbed the stillness that reigned supreme. As I stood upon the wharf in the broad splash of light that followed me from the sitting-room windows, I saw another canoe cross the pathway of uncertain light upon the water, and disappear at once into the impenetrable gloom that lay beyond. This time I saw more distinctly than before. It was like the former canoe, a big birch-bark, with high-crested bows and stern and broad beam. It was paddled by two Indians, of whom the one in the stern--the steerer--appeared to be a very large man. I could see this very plainly; and though the second canoe was much nearer the island than the first, I judged that they were both on their way home to the Government Reservation, which was situated some fifteen miles away upon the mainland.
