Lincoln writes Robert Boal, promising to be at Lacon September 30, 1856 if possible. He also urges Frederick Hecker, exiled German revolutionist of St. Clair County, to speak in Springfield on 25th, "when we expect to have a large mass-meeting." He declines invitation to speak in Iowa on 23rd. Iowa is safe, but in Illinois "much hard work is still to be done." Abraham Lincoln to Robert S.
