Elated by Republican victory in recent city election, Lincoln writes Trumbull optimistic letter. He declines invitation of John M. Carson to lecture before Harrison Literary Institute of Chicago. "What time I can spare from my own business this season I shall be compelled to give to politics." He tells F. C. Herbruger that he cannot lecture at Harrison Literary Institute of Philadelphia. "I am not a professional lecturer." He writes Harvey G. Eastman of Poughkeepsie, N.Y. that he is unable to send photograph, but Eastman can "easily get one at New York. While I was there I was taken to one of the places where they get up such things." Abraham Lincoln to Lyman Trumbull, 7 April 1860, CW, 4:40-41; Abraham Lincoln to John M.
