A leading Welsh minister — and Welsh ministers are, I think, among the best preachers — was invited to preach an anniversary sermon before one of the great societies in London. Naturally anxious to disregard no propriety, he consulted the proper authority, the secretary. "Should I read my sermon?" "Oh, it is no matter, only bring some of your Welsh fire with you." " But you cannot, my dear sir, carry fire on paper." "No, that is true; but you may use the paper to kindle the fire."
