I am wondering if anyone has suggestions on how to answer the following questions: -- When Sam Clemens begins working (1847) in the Hannibal print shop of Joseph P. Ament, what kind of press and printing equipment was Ament using? Full rotary presses were just being introduced, and I doubt that Ament's small operation could have acquired or afforded one. But is there an archive which would give us clues as to what machines (Columbian, Ramage, stop-cylinder, whatever) he was actually using in 1847-51. -- When Sam subsequently works on his brother Orion's newspapers, what kinds of machines were in operation there? If nobody knows, can anyone suggest resources where we might turn up the answer? Bruce Michelson University of Illinois
