   Of course, if the Snark were sailing due west at six knots per hour, for the intervening four hours her latitude would not change. But if she were sailing due south, her latitude would change to the tune of twenty-four miles. In which case a simple addition or subtraction would convert the twelve o'clock latitude into eight o'clock latitude. But suppose the Snark were sailing southwest. Then the traverse tables must be consulted.
