Thank you to all who helped me sort out how to "tie in" MT to Newton, Mass., where I am planning to give my "Mark Twain on Postcards" talk later this year. It certainly pays to ask for help. Starting with a fast response from Barb Schmidt (first out of the blocks as always), I got all I asked for ... and more ... and better. Viz.: (1) I was conflating two incidents involving two different editors of The Atlantic; (2) The expedition was to Concord, in a different direction from Newton entirely; (3) And, trumping all, thanks to Vic Fischer: MT lectured years earlier at a church not 300 yards from the site of my planned talk. What a group! Henry Feldman Newtonville, Mass.
