CHAPTER CXXXIII.

PROFESSOR MORSE: HIS ELECTRO-MAGNETIC TELEGRAPH.

Communication of intelligence by concerted signals is as old as the

human race, and by all, except the white race, remains where it was

six thousand years ago. The smokes raised on successive hills to

give warning of the approach of strangers, or enemies, were found

to be the same by Frémont in his western explorations which were

described by Herodotus as used for the same purpose by the barbarian

nations of his time: the white race alone has made advances upon

that rude and imperfect mode of communication, and brought the art

to a marvellous perfection, but only after the intervention of

thousands of years. It was not until the siege of Vienna by the

Turks, that the very limited intelligence between the besieged in a

city and their friends outside, was established by the telegraph:

and it was not until the breaking out of the French revolution that

that mode of intelligence was applied to the centre and to the

circumference of a country: and at that point it was stationary

for fifty years. It was reserved for our own day, and our own

country to make the improvement which annihilates distance, which

disregards weather and darkness, and which rivals the tongue and the

pen in the precision and infinitude of its messages. Dr. Franklin

first broached the idea of using electricity for communicating

intelligence: Professor Morse gave practical application to his

idea. This gentleman was a portrait painter by profession, and had

been to Europe to perfect himself in his art. Returning in the

autumn of 1832, and while making the voyage, the recent discoveries

and experiments in electro-magnetism, and the affinity of

electricity to magnetism, or rather their probable identity, became

a subject of casual conversation between himself and a few of the

passengers. It had recently been discovered that an electric spark

could be obtained from a magnet, and this discovery had introduced a

new branch of science, to wit: magneto-electricity. Dr. Franklin's

experiments on the velocity of electricity, exceeding that of

light, and exceeding 180,000 miles in a moment, the feasibility

of making electricity the means of telegraphic intercourse, that

is to say of writing at a distance, struck him with great force,

and became the absorbing subject of his meditations. The idea of

telegraphing by electricity was new to him. Fortunately he did not

know that some eminent philosophers had before conceived the same

idea, but without inventing a plan by which the thought could be

realized. Knowing nothing of their ideas, he was not embarrassed

or impeded by the false lights of their mistakes. As the idea

was original with him, so was his plan. All previous modes of

telegraphing had been by evanescent signs: the distinctive feature

of Morse's plan was the self-recording property of the apparatus,

with its ordinarily inseparable characteristic of audible clicks,

answering the purposes of speech; for, in impressing the characters,

the sounds emitted by the machinery gave notice of each that was

struck, as well understood by the practised ear as the recorded

language was by the eye. In this he became the inventor of a new

art--the art of telegraphic recording, or imprinting characters

telegraphically.

Mr. Morse then had his invention complete in his head, and his labor

then begun to construct the machinery and types to reduce it to

practice, in which having succeeded to the entire satisfaction of a

limited number of observers in the years 1836 and '37, he laid it

before Congress in the year 1838, made an exhibit of its working

before a committee, and received a favorable report. Much time was

then lost in vain efforts to procure patents in England and France,

and returning to Congress in 1842, an appropriation of $30,000 was

asked for to enable the inventor to test his discovery on a line of

forty miles, between Washington and Baltimore. The appropriation

was granted--the preparations completed by the spring of 1844, and

messages exchanged instantaneously between the two points. The line

was soon extended to New York, and since so multiplied, that the

Morse electro-magnetic telegraph now works over 80,000 miles in

America and 50,000 in Europe. It is one of the marvellous results of

science, putting people who are thousands of miles apart in instant

communication with the accuracy of a face to face conversation. Its

wonderful advantages are felt in social, political, commercial and

military communications, and, in conjunction with the steam car, is

destined to work a total revolution in the art of defensive warfare.

It puts an end to defensive war on the ocean, to the necessity of

fortifications, except to delay for a few days the bombardment

of a city. The approach of invaders upon any point, telegraphed

through the country, brings down in the flying cars myriads of

citizen soldiers, arms in hand and provisions in abundance, to

overwhelm with numbers any possible invading force. It will dispense

with fleets and standing armies, and all the vast, cumbrous, and

expensive machinery of a modern army. Far from dreading an invasion,

the telegraph and the car may defy and dare it--may invite any

number of foreign troops to land--and assure the whole of them of

death or captivity, from myriads of volunteers launched upon them

hourly from the first moment of landing until the last invader is a

corpse or a prisoner.
