In Appendix C that accompanies _Mark Twain's Letters, Volume 5_ titled "Mark Twain's 1872 English Journals" Twain made the notation: "Write up Bummer & Lazarus & Emperor Norton." Although Twain had written about the two dogs Bummer & Lazarus during his newspaper days in San Francisco along with a few scattered comments about Norton, according to the reference notes for Appendix C, "Clemens is not known to have written anything further about Bummer, Lazarus, or Emperor Norton." (p. 625.) At least one web site devoted to Emperor Norton does list him as the model for the king in Huck Finn. Unfortunately, no citation for this theory is given. Barb
