George Byron Merrick, Old Times on the Upper Mississippi
“ The pilot at the wheel, directly over the boilers, is in blissful ignorance of the vital question agitating the engineer. He may at times have his suspicions, as the escape pipes talk in a language which tells something of the conditions existing below decks; but if the paddle wheels are turning over with speed, he seldom worries over the possibilities which lie beneath him. His answer to the question, whether the water is below the safety point, comes as he feels the deck lifting beneath his feet, and he sails away to leeward amid the debris of a wrecked steamboat. ”
