The solar system model that Barbara mentioned in her e-mail reminded me of a similar arrangement near the public library in Tsukuba, Japan. Along a walkway and starting at a point several hundred feet from the entrance to the library was a plaque about Pluto. The remaining planets were placed at their scale locations with the library entrance being the sun. Along the other side of the walkway and also following a scale were plaques marking the beginning of the geological eras(?). Thank you to Barbara for making us aware of the solar system model in northern Maine. Tom Thomas F. Vining V. F. Thomas Co.
