Keokuk, Stevenson, Rogers... Twain's "Campaign that Failed" doesn't mention his dates in Keokuk, following that "adventure," though "Roughing It" does, as I recall (hard to find either one here in Poland). But I had the impression he was in and out of Keokuk quickly, to head west where there was no draft for either Union or Reb army. I for one never knew about Stevenson in K, and I don't know if his extensive stay in N. California coincided with any period of Twain's tarrying there. There's a fine park named for Stevenson, towns for Twain and Harte, even one for them-both, when the separate names were used up. My guess is that a local librarian in Keokuk has the answer to whether they could have crossed paths there, and someone in Sonoma or Marin county regional libraries (cities of Sonoma or San Rafael) the same for that locale. Librarians love doing it. If Mora and Braham, Minnesota or their counties (Kanabec and Isanti, respectively) have their own efficient websites, I would guess that Keokuk, further downstream, would have a good one. Phone calls are too expensive here to play around with browsing overseas websites, but I'll bet you can find the library of the Keokukers easily from your place. (Keokuk's county is Lee, as I look at the German-made atlas I have, not Twain, not Stevenson. Which Lee?) Richard R, Lodz, Poland
