"What fun we had with Aunt Emma's boys, Joseph, Frederick, Alexander and David. How we raced through the house playing hide and seek. My favorite hiding place was in an old wardrobe which contained the mummies, and it was in here that I would creep while the others searched the house. There were three mummies: The old Egyptian king, the queen and their daughter. The bodies were wrapped in seven layers of linen cut in thin strips. In the arms of the Old King, lay the roll of papyrus from which our prophet translated the Book of Abraham.
