 The trial was held September 8-24, but Lincoln did not visit Davenport. The question of whether he visited the site of the bridge has been and is a matter of controversy. The evidence that he did is contained in a copy of a letter purportedly written by N. B. Judd to Lincoln, September 4, 1857, in which he mentions Lincoln's trip to Rock Island ``last Tuesday,'' which would have been September 1. This purported copy of Judd's letter is of questionable authenticity.
