ch as the
tremendous leap of human voice across the line from New York to San
Francisco appealed to the mind, there is something infinitely more
fascinating in this new triumph of the engineer. The human mind can
grasp the idea of the spoken word being carried along wires, though
that is difficult enough, but when we try to understand its flight
through space we are faced with something beyond the comprehension of
the layman and almost past belief.

We have seen how communication has developed, very slowly at first,
and then, as electricity was discovered, with great rapidity until man
may converse with man at a distance of five thousand miles. What
the future will bring forth we do not know. The ether may be made to
accomplish even more wonderful things as a bearer of intelligence.
Though we cannot now see how it would be possible, the day may come
when every automobile and aeroplane will be equipped with its wireless
telephone, and the motorist and aviator, wherever they go, may
talk with anyone anywhere. The transmission of power by wireless is
confidently predicted. Pictures have been transmitted by telegraph. It
may be possible to transmit them by wireless. Then some one may find
out how to transmit moving pictures through the ether. Then one might
sit and see before him on a screen a representation of what was then
happening thousands of miles away, and, listening through a telephone,
hear all the sounds at the same place. Wonders that we cannot even now
imagine may lie before us.

NEW DEVELOPMENTS OF THE TELEGRAPH

_By F.W. Lienan, Superintendent Tariff Bureau, Western Union Telegraph
Company_

The invention of Samuel F.B. Morse is unique in this, that the methods
and instruments of telegraph operation as he evolved them from his
first experimental apparatus were so simple, and yet so completely met
the requirements, that they have continued in use to the present day
in practically their original form. But this does not mean that there
has not been the same constant striving for betterment in this as in
every other art. Many minds have, since the birth of the telegraph,
occupied themselves with the problem of devising improved means of
telegraphic transmission. The results have varied according to the
point of view from which the subject was approached, but all, directly
or indirectly, sought the same goal (the obvious one, since speed is
the essence of telegraphy), to find the best mea
