CODE FOR SEMAPHORE SIGNALLING
Note: The extended arm should always make a straight line with the flag staff.
From the very beginning practice reading as well as sending. It is harder to do and requires more practice. Instructors should always face the class in giving a lesson; in this way the pupil learns to read at the same time as she is learning to make the letters. This principle applies to all visual signalling.
Whistle Signals
1. One blast, "Attention"; "Assemble" (if scattered).
2. Two short blasts, "All right."
3. Four short blasts, calls "Patrol Leaders come here."
4. Alternate long and short blasts, "Mess Call."
