When Charles Shamey was a teacher and principal, he never forgot the wonderful years and the many fine teachers at Salina School, in Dearborn, Michigan, in the same neighborhood as the famous Ford Rouge Plant. Throughout the years, he created for his students, many of the same activities told in this story. As an educator, he lives by the German phrase, "Komins der lachelenden kinder," - land of smiling children. For smiling children are happy children. Happy children are eager to learn. This story is about happy kids. City kids with the adventuring spirit of a Huck Finn or a Tom Sawyer. The author is an avid walker and any walker will tell you that they reach back in their memories and reminisce the wonderful days gone by. So here it is, after walking through Henry Ford Museum and Greenfield Village and the local park for many years, he shares those golden memoirs in his story, "Dr. Bones and the Time Machine."
