The General Service Code, given herewith, also called the Continental Code and the International Morse Code, is used by the Army and Navy, and for cabling and wireless telegraphy. It is used for visual signalling by hand, flag, Ardois lights, torches, heliograph, lanterns, etc., and for sound signalling with buzzer, whistle, etc.
The American Morse Code is used for commercial purposes only, and differs from the International Morse in a few particulars. A Scout need not concern herself with it because it would only be used by the Scout who eventually becomes a telegrapher, and for this purpose the Western Union Company offers the necessary training.

GENERAL SERVICE CODE
The flag used for this signalling is square with a smaller square of another color in the center. It may be either white with the smaller square red, or red with the smaller square white. A good size for Scout use is 24 inches square with a center 9 inches square, on a pole 42 inches long and one-half inch in diameter.
There are but three motions with the flag and all start from, and are completed by, return to position, which means the flag held perpendicularly and at rest directly in front of the signaller.
Signaller should stand erect, well balanced on the arches of the feet. The butt of the flag stick is held lightly in the right hand; the left hand steadies and directs the flag at a distance from six to twelve inches above the right on the stick. The length of the stick will determine the position of the left hand; the longer the stick the further apart must the hands be placed in order to obtain the best balance.
DOT: To make the dot, swing the flag down to the right until the stick reaches the horizontal and bring it back to Position.
DASH: To make the dash, swing the flag to the left until it reaches the horizontal and bring it back to Position.
