A conscientious desire on the part of the present historian to tell his story in a complete and workmanlike fashion from the very beginning raises the inevitable question. What was the beginning? Not always an easy question to answer offhand; for if we reflect upon certain episodes in our lives and try to track them to their beginnings, we are apt, on further cogitation, to discover behind those beginnings antecedents yet more remote which have played an indispensable part in the evolution of events.As to this present history the whole train of cause and consequence might fairly be supposed to have been started by Mr. Pottermack's singular discovery in his garden. Yet, when we consider the matter more closely, we may doubt if that discovery would ever have been made if it had not been for the sun-dial.
