It came only gradually alive for us. As the years passed the utilitarian stranger with whom we traded became an acquaintance, and the acquaintance a friend. Here and there a man or a woman stepped out of the background, as it were, of a dim picture, and became a living being. One of the first was the old gunsmith of whom I have already written. Another was Doctor North-though he really lived outside the town-whom we came to know late in his career. He was one of the great unknown men of this country; he lives yet in many lives, a sort of immortality which comes only to those who have learned the greatest art of all arts, the art of life.
