208 The letters A to I also stand for the figures 1 to 9 (K standing for O), 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 acknowlledge by making J. The signaler 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

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 high, and waved as though pushing forward, at full extent of arm, or whistle a succession of slow blasts means "Extend," "Go farther out," "Scatter."

Hand or flag held high, and waved rapidly from side to side, at full extent of arm, or a succession of short, quick blasts on the whistle, means "Close in," "Rally," "Come here," "Danger," "Cattle on track."
