With Morse the turning point was reached in 1827 when, some years

after his return from England, he attended a course of lectures in New

York on the subject of electromagnetism. What he then heard fired his

imagination, and led him, during a second visit abroad, to study more

closely the nature of electricity. He specially became interested in

the possibility of utilizing this great natural force as a medium for

long-distance communication, and when homeward bound, in the autumn of

1832, applied himself to this one problem to such good purpose that

before landing in New York he was able to show to his fellow passengers

plans of the instrument that was to immortalize his name.

It was not until five years afterward, however, that Morse made the

first working demonstration of his invention, which by most people was

regarded as a scientific toy rather than a creation of the highest

practical utility. And a scientific toy it remained until, after a

heartbreaking struggle to secure the necessary financial aid, Morse

persuaded Congress in 1843 to appropriate $30,000 for the construction

of a telegraph line between Washington and Baltimore. The first message

to be flashed over this line, May 1, 1844, was the news of the

nomination of Henry Clay for the presidency; and with the sending of

that message one of the greatest inventions in the history of mankind

definitely gained recognition as an accomplished fact.

Alexander Graham Bell, experimenting in the same field of long-distance

communication by the aid of electricity, was more fortunate in

securing early acknowledgment of the merits of his telephone, a public

demonstration of which was given at the Centennial Exhibition in 1876.

Connected with this invention a most interesting story is told. Bell,

it is said, was experimenting with a device for multiplex telegraphy,

when the accidental snapping of a wire sent a sound vibrating through

another wire which had attached to it at each end a thin sheet-iron

disk a few inches in circumference. At once Bell asked himself if the

sound could be repeated. Experiment showed that it could, and the query

then suggested itself to him, Could vocal sounds be thus transmitted?

Forthwith he set himself to the task that resulted, after many

failures, in the creation of the telephone.

But even in the case of this marvelous instrument it was for a long

time impossible to obtain the necessary financial support. When, in

1877, Bell took the telephone to England, he could find no purchaser

for half the European rights at $10,000, and in this country a personal

friend declined to advance $2,500 for a half interest. Today, so it

is stated, there are in use in the United States alone approximately

seven and a half million telephones.
