USING THE FLAG 



189 



Section 124 Wigwag Signalling 



Flag, torch, hand lantern, or the be-am of a searchlight may be employed. 



1 MOTIONS 



One position and three motions are used. The one position is with the flag or 

 other appliance held vertically, the signaling n facing directly toward the station with 

 which it is desired to communicate. 



The first motion (the "dot" of the International Morse code or "1" of the Myer 

 code) is to the right of the sender, will embrace an arc of 90 starting from the 

 vertical and returning to it, and will be made in * plane at right angles to the line 

 connecting the two stations. 



The second motion (the "dash" of the Internationa? or "2" of the Myer code) is a 

 similar motion to the left of the sender. 



The third motion ("front" or "3" of the Myer code) is downward directly in front 

 of the sender and instantly returned upward to the first position. This is used to indi- 

 cate a pause or conclusion.

2 HANDLING THE FLAG 



Make all motions rapidly. To prevent entangling of the flag on its stuff, skilful 

 handling acquired by practice is necessary. It is accomplished by making a scoop of 

 the flag against the wind, the movement describing an elongated figure 8, thus 00. The 

 motions should be made so as to display in the lateral waves the whole surface of the 

 flag toward the point of observation.
