Sixty years ago this month, the October 1963 issue of Boys’ Life magazine showed Scouts the art of wigwagging, which is the “other” method of sending a message with signal flags. The most common method, semaphore, uses two flags, and each letter is sent by holding the flags in a certain position. Wigwag, on the other hand, uses a single flag, and uses Morse code. For a dot, the flag is waved in a figure eight to the sender’s right. The dash is formed by waving the flag to the sender’s left.

For a break between letters, the flag is held upright. After each word, the flag is held down.
