Knox College displays its banner supporting Abraham Lincoln as he speaks before a crowd during his fifth debate with Sen. Stephen A. Douglas in Galesburg, Ill., on Oct. 7, 1858. Artist Victor Perard drew this sketch of Old Main, the central building on the Knox College campus. These debates had no moderators. The candidates took it in turns to open each debate with a one-hour speech, then the other candidate had an hour and a half to rebut, and finally the first candidate closed the debate with a half-hour response. (AP Photo)
