These notes on the Church's Year were originally intended to be a chapter in the first volume of this series, The Science of the Sacraments. It was found, however, that that book was already becoming un wieldy, and that there was more to be said about the ecclesiastical year than could be compressed into a single chapter; so it seemed best to devote a separate volume to its consideration. This has also made it possible to add to it a few miscellaneous addresses on points of importance.
