I've uploaded an improved version of this reading. The performance is the same but I've utilized additional filtering from audacity and hopefully made the slideshow more interesting.
The Innocents Abroad - Chapter 6
Along with Chapter 5, this chapter describes Twain's visit to the Azores. Attached is an image from the first letter of the journey to the Daily Alta California.
A note in Traveling with the Innocents Abroad by Daniel Morley McKeithan, mentions this was published August 2, 1867. The masthead of the image copy I have has the date as August 25.
