James Thomas Telephone Museum: James M. Thomas pioneered the non-Bell independent telephone industry and this museum is dedicated to his accomplishments. It features a wooden underground conduit, which contained early Western Union cables that ran beneath the streets of Chillicothe. And an old switchboard, phone directories as early as 1897 and many other telephone equipment displays.
