The Scouter calls out the name of an object and signals
a letter in Semaphore or Morse.
Each Scout must then
try and be first in calling out the name of an object of the
class called, beginning with the letter signaled.
Thus the Scouter calls "fish" and signals "S".
Scouts
may call out "Shark" or "Sprat," or any other fish
beginning with "S".
Other examples are:
"Book," " T ": Treasure Island.
"Flower," "D": Daffodil
"Tree," "H": Hornbeam
