The Story of the Atlantic Cable
Bright, Charles, Sir
Transatlantic cables
The end of the Niagara's cable was sent on board the Agamemnon, the
splice was made, a bent sixpence put in for luck, and at 2.50
Greenwich time it was slowly lowered over the side and disappeared
forever. The weather was cold and foggy, with a stiff breeze and
dismal sort of sleet, and as there was no cheering or manifestation
of enthusiasm of any kind, the whole ceremony had a most funereal
effect, and seemed as solemn as if we were burying a marine, or
some other mortuary task of the kind equally cheerful and
enlivening. As it turned out, however, it was just as well that no
display took place, as every one would have looked uncommonly silly
when the same operation came to be repeated, as it had to be, an
hour or so afterward. It is needless making a long story longer, so
I may state at once that when each ship had paid out three miles or
so, and they were getting well apart, the cable, which had been
allowed to run too slack, broke on board the Niagara owing to its
overriding and getting off the pulley leading on to the machine.
The break was of course known instantly, both vessels put about and
returned, a fresh splice was made, and again lowered over at half
past seven. According to arrangement, 150 fathoms were veered out
from each ship, and then all stood away on their course, at first
at two miles an hour, and afterward at four. Everything then went
well, the machine working beautifully, at thirty-two revolutions
per minute, the screw at twenty-six, the cable running out easily
at five and five and a half miles an hour, the ship going four. The
greatest strain upon the dynamometer was 2,500 lbs., and this was
only for a few minutes, the average giving only 2,000 lbs. and
2,100 lbs. At midnight twenty-one nautical miles had been paid out,
and the angle of the cable with the horizon had been reduced
considerably. At about half past three forty miles had gone, and
nothing could be more perfect and regular than the working of
everything, when suddenly, at 3.40 A.M. on Sunday, the 27th,
Professor Thomson came on deck and reported a total break of
continuity; that the cable, in fact, had parted, and as was
believed at the time, from the Niagara. The Agamemnon was instantly
stopped and the brakes applied to the machinery, in order that the
cable paid out might be severed from the mass in the hold, and so
enable Professor Thomson to discover by electrical tests at about
what distance from the ship the fracture had taken place.[31]
Unfortunately, however, there was a strong breeze on at the time,
with rather a heavy swell, which told severely upon the cable, and
before any means could be taken to ease entirely the motion on the
ship, it parted a few fathoms below the stern-wheel, the
