"The Scientific American Boy The Camp at Willow Clump Island"

S. Army "Manual of Signaling." Fred, the tailor of our
camp, made us two white flags with red centers. Each flag was two feet
square and was fastened to a light staff about five feet long. Then we got
out the manual and practised sending signals, at first within shouting
distance, until we got to be quite expert.

Wigwag Signals.
[Illustration: Fig. 147. Ready.]
[Illustration: Fig. 148. First Movement.]
[Illustration: Fig. 149. Second Movement.]
[Illustration: Fig. 150. Third Movement.]
There were only three different movements that could be made with flags,
but in the book different combinations of these movements were given to
represent each letter of the alphabet and the numbers from 1 to 0. All
these movements were begun and ended by holding the flagstaff upright,
directly in front of the body, as shown in Fig. 147. The first movement
was to swing the flag down to the right and back (Fig. 148), the second to
the left and back (Fig. 149), and the third forward and back (Fig. 150).
The following table gives the different combinations used for various
letters:
