Everett Emerson's _Mark Twain, A Literary Life_ has a brief
discussion of  the Hawaiian novel.  Begun in January 1884,
it was a novel about Bill Ragsdale, a half-caste interpreter.
According to Emerson, very little survives of the manuscript --
only a few pages.  Emerson also references an article by
Stephen Sumida titled "Reevaluating Mark Twain's Novel
of Hawaii," American Literature (Dec. 1989), pp. 586-609.
