There is a wonderful chapter in Everett Emerson's literary biography of
Twain about losing the Hartford home.--and about the image of burning homes
in later fictions.  Do not have the book handy to check for page numbers.

I also have some comments about Twain's yearning in life to find a home
(along with certain of his characters, like Huck) in my forthcoming work
--esp. At the end of it.

Your comments also remind me of George Harris in the Quaker village in
UTC--see for example p. 122 in the Norton edition:  "This indeed was a
home--home,--a word that George had never yet known. . . .
