In response to Robert Dagnall-- I can't claim (by any means) to have read everything Twain wrote. But in my editorial work on SATIRE OR EVASION? I read what a number of commentators had to say on the subject, and so far as I know, no one has found that Twain ever used the phrase "Nigger Jim." Further, my impression of his relation to his work is that he would not have done so. Jim Leonard
