According to _Mark Twain's Letters, Vol. II_ (p. 3) in a lecture in
San Francisco Twain identified Edward Jump as the artist who would
illustrate his book about the Sandwich Islands -- a book that never
materialized.

In 1938 William Murrell wrote in _A History of American Graphic
Humor_ (p. 7):  "Art Young recently showed me an interesting letter he
received a few years ago from a man named Hoatland, commenting
on a drawing of Mark Twain by Young, and supplying some personal
reminiscences of Twain in Washington in or about 1868.  Hoatland
roomed in a house where Twain and Jump also had rooms.   The
letter, besides relating an amusing story of Twain and Jump which
Mr. Young may release some day, contains some items about Jump"

Was the Hoatland letter concerning Twain and Jump ever published?
