It was in the season of Christmas that I came out of my little garden in that "field of the beeches" between the Chilterns and the Thames, and began to walk backwards through history to the place from which Christmas came. For it is often necessary to walk backwards, as a man on the wrong road goes back to a sign-post to find the right road. The modern man is more like a traveller who has forgotten the name of his destination, and has to go back whence he came, even to find out where he is going.
