Transatlantic cables
"I cannot tell you how I have felt since our success. It is only
seventeen months since I first walked up to the top of the paddle-box of
this ship at Sheerness, upon a dark, rainy night--reviewed my past
career in my mind, and tried to look into the future, to see what I had
undertaken, and realize if possible what this new step would develop. I
cannot say I believed much in cables; I rather think I did not; but I
did believe Mr. Field was an earnest man, of great force of character,
and working under a strong conviction that what he was attempting was
thoroughly practicable; and I knew enough of the names with which he had
associated himself in the enterprise to feel that it was a real, true,
honest effort, worthy of all the energy and application of one's
manhood; and come what might in the future, I resolved to do my very
utmost, and to do nothing else until it was over. More completely
however than my resolve foreshadowed, I dropped inch by inch, or step by
step, into the work, until I had no mind, no soul, no sleep, that was
not tinged with cable. In a word I accuse Mr. Field of having dragged me
into a vortex, that I could not get out of, and did not wish to try--and
the sum total of all this is, to lay a thread across an ocean! Dr.
Russell compared it to an elephant stretching a cobweb, and there lay
its very danger: the more you multiply the mechanism, the more you
increase the risk."
[B] "All during the night the process of picking up was carefully
carried on, the Big Ship behaving beautifully, and hanging lightly over
the cable, as if fearful of breaking the slender cord which swayed up
and down in the ocean. Indeed, so delicately did she answer her
helm, and coil in the film of thread-like cable over her bows, that
she put one in mind of an elephant taking up a straw in its
proboscis."--Russell.
[C] So exquisitely sensitive was the copper strand, that as the Great
Eastern rolled, and so made the cable pass across the magnetic meridian,
the induced current of electricity, incomprehensibly faint as it must
have been, produced nevertheless a perceptible deviation of the ray of
light on the mirror galvanometer at Foilhommerum.--_London Times._
CHAPTER XV.
PREPARING TO RENEW THE BATTLE.
The expedition of 1865, though not an immediate success, had the moral
effect of a victory, as it confirmed the most sanguine expectations of
all who embarked in it. The great experiment made during those four
weeks at sea, had demonstrated many points which were most important
elements in the problem of Ocean Telegraphy. These are summed up in the
following paper, which was signed by persons officially engaged on board
the Great Eastern:
1. It was proved by the expedition of 1858, that a Submarine
Telegraph Cable could be laid between Ireland and Newfoundland,
and messages transmitted through the same.
By the expedition of 1865 it has been fully demonstrated:
