As the crashing of the spark sounds to these learners, the letter being transmitted is seen; this enables them to learn
to send and receive much more quickly.
it becomes harder still to follow them.
But all the time his ability to recognize
by ear certain signals is increasing, together
with his facility in getting down
what they mean on paper. He begins to
depend less and less on the eye and more
and more on the ear and hand. Presently,
he is able to dispense with the
flasher altogether and graduates to another
circuit where the ear needs no
assistance.
The advantages of this simple device
are at once apparent. The student is no
longer compelled to burden his conscious
memory by visualizing a large
number of confusing combinations of
dots and dashes. He scarcely ever needs
to see the dots and clashes at all. His ear
and hand do the memorizing and continued
repetition in time makes the
action subconscious and mechanical.
The device has been adopted by the
government naval authorities and is in
use at the LTiiited States Naval Training
Station on Goat Island in San Francisco
Bay. Mr. Riggins soon expects to extend
his flash-light attachment so as to
include the numerals from zero to nine,
the names of the marks of punctuation
and the stock calls and abbreviations.
