You may be remembering Clemens's first encounter with Lilian Aldrich,
Thomas Bailey Aldrich's wife, in 1871; and Justin Kaplan's account of it in
Mr. Clemens and Mark Twain, pp. 144-45. See also Mark Twain in Eruption,
292-303; and Lilian Aldrich's Crowding Memories, pp. 127-132.

Mark Twain's Letters, Volume 3, 481-86, gives Clemens's lecture schedules
for the 1868-69 and 1869-70 tours. He lectured in Newtonville (one of the
villages that made up Newton), Mass., on 29 November 1869, at the
Congregational Church, and according to the Newton Journal his talk
"elicited shouts of laughter. Three divines of the town were noticed as
present, apparently in a most enjoyable frame of mind" (414 n. 2). See also
Mark Twain's Letters,.Volume 4, passim, for Clemens's first encounters with
Aldrich and pp, 484-86 (for a description of a memorable lunch including
Aldrich, Clemens, Harte, Keeler, Howells, and James T. Fields. The lecture
calendar for 1871-72, which also includes a number of Massachusetts towns,
is on pp. 557-60.
