Quotation by Henry David Thoreau

Setting out on our return to the river, still at an early hour in the day, we decided to follow the course of the torrent.... This ravine had been the scene of an extraordinary freshet in the spring, accompanied by a slide from the mountain.... At one place we were startled by seeing, on a little sandy shelf by the side of the stream, the fresh print of a man's foot, and for a moment realized how Robinson Crusoe felt in a similar case; but at last we remembered that we had struck this stream on our way up, though we could not have told where, and one had descended into the ravine for a drink.
