Thank you all for this lead. I've found copies available on Amazon, some for rather exorbitant amounts and others for less than $20. I've ordered a copy. Meanwhile I did find a source of pdfs at California Digital Newspaper Collection, cdnc.ucr.edu The pdfs are readable but the scanned text is almost useless. If you wish text copies you'd probably save time by just typing the letters out rather than trying to correct the scanned text. My avatar has been doing readings from The Innocents Abroad in Second Life, the virtual on-line world. I created a web page from the first chapter that includes a link to the YouTube recording as well as an image of the Letter form Mark Twain published August 18, 1867, written June 6, 1867, the day before the Quaker City left the dock. http://bsh.bscottholmes.com/twain/innocents/chapter1
