Read it through once

Many and many a time did this ancient mariner appear on the scene in the above fashion, and spread disaster and humiliation around him. If one might believe the pilots, he always dated his islands back to the misty dawn of river history; and he never used the same island twice; and never did he employ an island that still existed, or give one a name which anybody present was old enough to have heard of before. If you might believe the pilots, he was always conscientiously particular about little details; never spoke of 'the State of Mississippi,' for instance--no, he would say, 'When the State of Mississippi was where Arkansas now is,' and would never speak of Louisiana or Missouri in a general way, and leave an incorrect impression on your mind--no, he would say, 'When Louisiana was up the river farther,' or 'When Missouri was on the Illinois side.'
