The Mississippi is, as we see it, central to the narrative of Huck Finn. It allows Huck and Jim to escape from an abusive home and an oppressive society, respectively. “The river is literal, yet it is metaphorical at the same time,” writes literary scholar John Bird in his book "Mark Twain and Metaphor" (2007).Though Twain was intimately familiar with the Mississippi River from his days as a steamboat pilot, he chose novelistic truth over geographical accuracy while writing "Huckleberry Finn." The annotation for a scholarly edition of the novel, published in 2001, notes: “In the early chapters, the raft’s journey confirms well to a mathematical model… The model breaks down, however, soon after Cairo is passed… By the time the raft reaches Pikesville and the Phelps farm, which Mark Twain in several statements, firmly located in Arkansas, the disjunction between daily mileage and the passage of time is so great that some scholars argue for a location much further south, deep in Louisiana.”
