As we passed the Fourteen-Foot-Bank Lighthouse, and were able accurately to check our position on the chart, the log, a sort of nautical odometer that tells with a fair degree of accuracy the mileage travelled, was set in motion by heaving the rotator over the stern at the end of the log line. This rotator, set in motion by the passage of the water, twists the line to which it is attached, and the line, in turn, rotates the mechanism that records the mileage. It is very similar to the speedometer on the dash of the automobile except that it shows only the mileage. If we visit the bridge we may learn from the mate on duty that the barometer has fallen a little, and that we probably will have a touch of heavy weather by morning. We turn in in a comfortable stateroom situated in the deck house just aft the bridge, and, leaving the port open, for ventilation, go almost instantly to sleep, forgetful of the man at the wheel, who stands with his eyes fixed on the slightly moving compass card, turning the wheel first this way and then that, absolutely confident in the unerring compass. Outside, pacing back and forth on the bridge, is a mate, who went on watch at eight and will be relieved at twelve. As he leans over the port rail for a moment, the red rays from the port running light palely illuminate his tanned face. He is confident of his ship, confident of the engineers and firemen below, confident of the man at the wheel, and is calm and contented.
