At 2 p.m. on Sunday, Oct. 28, Dr. Tim Thoresen, former Champaign County Historical Society board member, will present a program based on his new book. All are welcome to the program, “Civil War, Agriculture, and Politics: Three Stories,” at the CCHS Museum, 809 East Lawn Ave.

Thoresen’s book, “River, Reaper, Rail: Agriculture and Identity in Ohio’s Mad River Valley, 1795–1885,” tells the story of farmers and technology in Champaign County and its Mad River Valley from the beginnings of white settlement in 1795 through the decades after the Civil War. His presentation will include a number of stories about Champaign County not included in the book, such as his account of the origination of the statue in Monument Square. Attendees can purchase signed copies at a reduced price.
