As to the "Tuesday Morning Club" -- is it possible the club in question was the Saturday Morning Club which Clemens helped organize in October 1876 for teenage girls? There is a brief entry on it in Rasmussen's _Mark Twain A to Z_. Paine also mentions it in his biography in Chapter 110, online at: http://www.boondocksnet.com/twaintexts/biography/paine_bio110.html It is also mentioned in the Mark Twain and W. D. Howells correspondence. Barb
