NOTE: The dots and dashes are formed by directing a steady 

 beam on the objective station and interrupting the beam by inter- 

 posing the hand or hat. The length of the flashes are determined 

 by the time one's hat is lowered below the beam. Telegraph then, 

 not as pressing a key downward but as thrusting the hat downward.
