Everyone-- This has been a very interesting and (for me) informative thread. Thanks to Steve for starting it with his question. Bob--your "Black Jack" info provides an additional historical note, but do the dates work? I would add to the discussion the Dred Scott decision, which began in MO the year of the novel (give or take--the novel putatively takes place in 1845, and the D. Scott case began in MO in 1846). The case was finally notoriously decided by the U.S. Supreme Court in 1857. Readers in 1885 would have known about that famous case and remembered it, and would have remembered what happened to Missouri slaves who went to Illinois and claimed to be free. Jim, a Missouri slave, is exercising good sense to decide not to go there. Twain had two time periods to contend with--1885, when the novel was published, and 1845. He had to have things happen in the novel that would be plausible in 1885, that his readers in 1885 would think were probable back in 1845. Many alive then would think that they knew very well how things had been back then. They wouldn't have been duped by an obviously crazy scheme. The way to get to the north was through Ohio, even in the 1840s before the Fugitive Slave Law was passed in 1850. I don't think that the early (pre-1850) underground railroad went through Illinois--I don't know for sure, but I think there were no "stations" on the URR in Illinois then. (Thanks to Jim Edstrom for info about the Turner book on the URR in Illinois--but I think, that was post-1850.) In any event, I believe that conventional wisdom in 1845 said that the way to get free was to go north through the state of Ohio. That plan would have seemed right to the novel's first readers. And for several good factual reasons that have been enumerated by these recent emails, it makes good sense still. Terry Oggel
