Some additional Twichell resources: Leah A. Strong, _Joseph Hopkins Twichell: Mark Twain's Friend and Pastor_ (Athens: University of Georgia Press, 1966). Mark Twain -- Joseph H. Twichell Correspondence, American Literature Collections, Beinecke Library, Yale University. I don't remember if Twichell's letters are in this collection but it is a good source for Twain's letters to Twichell. Albert B. Paine edited a number of the letters (often silently) before including them in his 1917 edition of _Mark Twain's Letters_. Kenneth R. Andrews, _Nook Farm: Mark Twain's Hartford Circle_ (Cambridge, MA: Harvard University Press, 1950). The article by Twichell that Barbara Schmidt mentioned is online in the Cornell University section of the Making of America project: Joseph H. Twichell, "Mark Twain" http://moa.cit.cornell.edu/dienst/moabrowse/ MOA-JOURNALS2:HARP-0092/827/1:GIF89:100 Jim Zwick
