Just as Darwin gains my trust, he makes the outrageous claim that he crosses the Andes from Santiago, Chile to "the Republic of Mendoza". The Chileans check his passport on the west side of the Andes, and the "Mendozans" check it on the east. Joseph Conrad also mentions this mythical country in his story "Gaspar Ruiz" - clearly goofing on Darwin. For shame, Charles.
More specimen collecting: on the island of Chiloe, Darwin sneaks up on a rare fox which is watching the sailors and clobbers it with his geological hammer. "This fox, more curious or more scientific, but less wise, than the generality of his brethren, is now mounted in the museum of the Zoological Society." Darwin has a pretty good sense of humor. *
The edition I am reading is about 500 pages. The bulk of the book, 350 pages, is about Argentina and mainland Chile, the Andes and Pampas and Patagonia. The single chapter on the Galapagos Islands is only 30 pages. A surprise to me.
There is a very helpful website about Darwin and the Beagle voyage here, with detailed maps. Notice that the map of "Mendoza" is conspicuously absent!
*Turns out the common species name is actually "Darwin's fox".
