Twain's Begum of Bengal speech appears in Paul Fatout's _Mark Twain
Speaking_, p. 577-583 (Univ. of Iowa Press, 1978).  The speech was
given at the Lord Mayor's Banquet for Mark Twain, Town Hall, Liverpool,
July 10, 1907.  The original Begum of Bengal anecdote is from
Dana's _Two Years Before the Mast_, chapter 35.  (However, for
some unexplained reason, the passage has been edited out of
some editions of Dana's book.)
