Still reading notes from "Heretical Fictions", I note the idea that Jim 
did not tell Huck about the dead body being Pap as because Jim did not 
want Huck to abandon him in his quest to escape slavery.  I had always 
had the impression that his motivation was to avoid telling Huck the 
"bad" news.  Thinking about it, now, I suppose I have been a bit naive.
