4. Alternate short and long blasts mean "Alarm," "Look out," "Be ready," "Man your alarm posts."
5. Three short blasts followed by one long one from the Captain calls up the patrol leaders.
Any whistle signal must be instantly obeyed at the double as fast as you can run, regardless of anything you may be doing.
