This is a "poem" from chapter 36 of Following the Equator.  Twain says
he used 66 location names from a list of 81.  From his published list
of towns, of the first 15, 5 do not seem to exist and I'm hesitant to
proceed without some advice.  From Shillingsburg's "At Home Abroad" I
got side tracked to a different poem, the Australian Poem.  Thinking it
was one and the same I tracked her source to the Parsons article in
Mark Twain Journal 22 on JSTOR.  No joy.  Primarily I'm concerned with
the proper Australian pronunciations for these place names, imaginary
or not.  From these first 15 entries I've found pronunciations for 6 of
the locations.  I have not looked for any audio book versions of FTE.
