Read it through once

The river's earliest commerce was in great barges--keelboats, broadhorns. They floated and sailed from the upper rivers to New Orleans, changed cargoes there, and were tediously warped and poled back by hand. A voyage down and back sometimes occupied nine months. In time this commerce increased until it gave employment to hordes of rough and hardy men; rude, uneducated, brave, suffering terrific hardships with sailor-like stoicism; heavy drinkers, coarse frolickers in moral sties like the Natchez-under-the-hill of that day, heavy fighters, reckless fellows, every one, elephantinely jolly, foul-witted, profane; prodigal of their money, bankrupt at the end of the trip, fond of barbaric finery, prodigious braggarts; yet, in the main, honest, trustworthy, faithful to promises and duty, and often picturesquely magnanimous.
