In the effort to lengthen out the limited span of life into a greater
record of results, time becomes an object of economy. To save time is to
live long, and this in a pre-eminent degree is accomplished by the
telegraph. Of all the inventions which man has called into existence to
aid him in the fulfillment of his destiny, none so closely resembles man
himself in his dual quality of body and soul as the telegraph. It too
has a body and soul. We see the wire and the electro-magnet, but not the
vital principle which animates it. Without its subtile, pulsating,
intangible spirit, it is but dead matter. But vitalized with its
immortal soul it assumes the quality of animated existence, and through
its agency thought is extended beyond the limitations of time and space,
and flashes through air and sea around the world. Its moving principle
flows more silently than a summer’s zephyr, and yet it rises at times to
an angry and deadly crash in the lightning stroke. At once powerful and
elusive, it remained for Professor Morse to capture this wild steed,
and, taming it, place it in the permanent service of man. On May 24,
1844, there went over the wires between Washington and Baltimore the
first message--“What hath God wrought?” This was both prayer and praise,
and no more lofty recognition of the divine power and beneficence could
have been made. It was indeed the work of God made manifest in the hands
of His children.
Popular estimation has always credited Prof. Morse with the invention of
the telegraph, but to ascribe to him all the praise would do great
injustice to many other worthy workers in this field, some of whom are
regarded by the best judges to be entitled to equal praise.
The practical telegraph as originally used is resolvable into four
essential elements, viz., the battery, the conducting wire, the
electro-magnet, and the receiving and transmitting instruments.
The development of the battery began with Galvani in 1790, and Volta in
