I'd like to know more. Mr. Diefenderfer apparently died before 1985
(at the age of 80), without publishing anything that I've been able to
locate. Can anyone point me toward a source for further information
about Mr. Diefenderfer and his voyages?
And, in a more-or-less related matter, any reader who shares my
interest in small-boat adventures might want to visit Eric Eldrid's
"Eldritch Press" web-pages <http://eldred.ne.mediaone.net/index.html>
before they're shut down for good on 11 November. Mr. Eldrid has
scanned a number of out-of-copyright tales by Stevenson, Bishop,
MacGregor and others and made them all available on-line, often with
the original maps and illustrations.
The small boats in question aren't Potters, of course, but the site is
still worth a visit.
