Life on the Mississippi is a memoir by Mark Twain detailing his days as a steamboat pilot on the Mississippi River before the American Civil War.
The book begins with a brief history of the river as reported by Europeans and Americans, beginning with the Spanish explorer Hernando de Soto in 1542. It continues with anecdotes of Twain's training as a steamboat pilot, as the 'cub' (apprentice) of an experienced pilot, Horace E. Bixby. He describes, with great affection, the science of navigating the ever-changing Mississippi River in a section that was first published in 1876, entitled "Old Times on the Mississippi".
Although Twain was actually 21 when he began his training, he uses artistic license to make himself seem somewhat younger, referring to himself as a "fledgling" and a "boy" who "ran away from home" to seek his fortune on the river, and playing up his own callowness and naïveté.
