U, Y and the "annul," the right arm stands at C, the left
moving to the next point of the circle successively.

The numerical sign J (or alphabetical sign) and V--the right arm
stands at position for letter D the left arm only being moved.

{207}

W and X--the left arm stands at position for letter E, the right in
this case moving down 45 degrees to show letter X.

For the letter Z, the left arm stands at the position G--the right arm
crosses the breast taking the position F.

The letters A to I also stand for the figures 1 to 9 (K standing for
0), if you make the numerical sign to show that you are going to send
numbers followed by the alphabetical sign (J) when the figures are
finished. They will be checked by being repeated back by the receiving
station. Should figures be wrongly repeated by the receiving station
the sending station will send the "annul" sign (which is answered by
the same sign) and then send the group of figures again.

The sender must always face the station to which he is sending. On a
word failing to make sense, the writer down will say, "no," when the
reader will at once stop the sending station by raising both arms
horizontally to their full extent (letter R). This demand for
repetition the sending station will acknowledge by making J. The
signaller receiving the message will then send the last word he has
read correctly, upon which the sender will continue the message from
that word.

Whistle Signs

1. One long blast means "Silence," "Alert," "Look out for my next
signal." Also approaching a station.

2. Two short blasts means "All right."

3. A succession of long, slow blasts means "Go out," "Get farther
away," or "Advance," "Extend," "Scatter."

4. A succession of short, sharp blasts means "Rally," "Close in,"
"Come together," "Fall in," "Danger," "Alarm."

5. Three short blasts followed by one long one from scout master calls
up the patrol leaders--i.e., "Leaders, come here."

Any whistle signal must be instantly obeyed at the double--as fast as
you can run--no matter what other job you may be doing at the time.

Hand or Flag Signals

Hand signals, which can also be made by patrol leaders with their
patrol flags when necessary:

Hand waved several times across the face from side to side or flag
waved horizontally, from side to side opposite the face, means "No,"
"Never mind," "As you were."

Hand or flag held hig
