I have said that the house in which the lady and children dwelt was built on the top of a high hill. The house had pleasant grounds around it, in which the children could play. All round this enclosure was a fence made of stakes of the choicest wood. This fence was very needful, as the hill was in some parts so steep as to be dangerous, and the children might often have fallen down precipices but for this protection. On every one of the stakes was inscribed in golden letters a precious text, which glittered brightly in the sun, so that the fence was an ornament to the place, as well as a safeguard to the children. The name of the fence was Duty.
