Fred Dutton's story tells of the time before the gyro when ships were steered by magnetic compass and men had to estimate the degree of error in navigational calculations. Dutton recounts the terror of ships meeting and passing in the fog and the subtleties of handling ships at the docks. Serving under many captains on a dozen and a half vessels, he spices his account with profiles of ships' officers and crew and with details of deckhand work. Life on the Great Lakes provides a concentration of information that otherwise would need to be assembled in fragments from a hundred sources. Historians, folklore buffs, and ship lovers will discover details of vessel operation usually available only in the dialogue of a passing generation of very elderly sailors.
