"A Tramp Abroad — Volume 04" by Mark Twain is a travel book published in 1880. This fourth volume continues the humorous account of Twain's journey through central and southern Europe with his companion Harris. Though they intend to walk most of the way, the travelers frequently resort to other transportation as they navigate Germany, the Alps, and Italy. Twain portrays the American tourist who believes he grasps everything he encounters but actually understands nothing, creating comedy through misperception and cultural misunderstanding.
