Following the Equator (sometimes titled More Tramps Abroad) is a non-fiction social commentary in the form of a travelogue published by Mark Twain in 1897.
Twain was practically bankrupt in 1894 due to a failed investment into a "revolutionary" typesetting machine. In an attempt to extricate himself from debt of $100,000 (equivalent of about $2.5 million in 2010) he undertook a tour of the British Empire in 1895 at age 60, a route chosen to provide numerous opportunities for lectures in English.
The book is a social commentary, critical of racism towards blacks, Asians, and Indigenous groups; oppressive imperialism in the British Empire; and religious intolerance through missionary efforts.
Although this social commentary is the great import of the book, it is notable that Twain also included a number of fictional stories in the body of what is otherwise a non-fiction work. In particular, the story of how Cecil Rhodes made his fortune -- by finding a newspaper in the belly of a shark -- and the story of how a man named Ed Jackson made good in life out of a fake letter of introduction to Cornelius Vanderbilt, were anthologized in Charles Neider (ed) The Complete Short Stories of Mark Twain, (Doubleday, 1957) where they are presented as fiction.
