One of the major themes I have tried to thread through my Twain's 
Geography site is his views on Industrialization, a major cultural shift 
during his lifetime.  I have found a book that apparently addresses this 
but have found no reviews on file in the Mark Twain Forum.  I've ordered 
a copy from AbeBooks.  What prompted me was Sam's Letter to Howells in 
March of '88.  Are there any thoughts on this book?
