Signaling

Signaling can be done by means of a red and white flag, and the code used by the wig wag system, or one similar can be used.

Fig. 175 shows the rod on which the two signals are used. Screw-eyes would be better than pulley wheels as there would be no slipping out of the grooves, and there would not be enough friction to be objectionable. The cord operating the two signals should be continuous, passing from the ground to one signal, thru the screw-eye above, then thru the other screw-eye to the second signal and from that back to the ground. The distance from the signal to the screw-eye should be convenient for manipulation by the operator, for while one flag is up the other is down, and this distance corresponds to the pull and relaxation of the hands of the operator. The signals can be red and white flags, or a device like Fig. 176, in which a full surface of color would always be in view. Sometimes a flag flying directly toward or away from you is not a very large object to see. This last device is made of two good sized cardboard disks, each cut half way thru, Fig. 177, and set at right angles to each other. The red and white is placed there to help in location of the other signals, as to up and would read, red and light, that is r is red or right, while l is left or light. So the same code operates for both. The center black square down and right and left. The code given is one that we have used somewhat, but not many have mastered it as yet. It can be used for night signalling, as red and white or light, would read r and l too.

We will illustrate with the letter b. The code reads LRR L, At night this would be flashed: light, then red, red again, then light. On the kite signal we would run up the light signal, then the red, red again, and then the light. Just so with the wigwag. The wig wag flag would be waved to left then two to the right then one to the left and back again to center. If we were spelling out BOY, a little pause would be made after B had been signalled, then left, right, or light, red would be signalled, and after a slight pause again, the three reds or three waves of the wig wag flag to the right. A little longer pause between words and then the next word would follow.
