ROBBING FOG OF ITS TERRORS

The mariner has long since learned to be exceedingly cautious about depending upon aerial sound signals, even when near. Experience has taught him that he should not assume that he is out of hearing distance of the position of the signal station because he fails to hear the sound; that he should not assume that because he hears a fog signal faintly he is at a great distance from it, nor that he is near because he hears the sound plainly.”—EXTRACT FROM MONOGRAPH OF HYDROGRAPHIC OFFICE, U.S. NAVY,
