The Story of the Atlantic Cable
Bright, Charles, Sir
Transatlantic cables
By noon of the 8th we had paid out 40 miles of cable, including the
heavy shore end. Our exact position at the time was in lat. 50° 59´
36´´ N., long. 11° 19´ 15´´ W., and the depth of the water
according to the soundings taken by the Cyclops--whose course we
nearly followed--ninety fathoms. Up to 4 P. M. on that day the
egress of the cable had been regulated by the power necessary to
keep the machinery in motion at a slightly higher rate than that of
the ship; but as the water deepened it was necessary to place some
further restraint upon the cable by applying pressure to the
friction-drums in connection with the paying-out sheaves. By
midnight 85 miles had been safely laid, the depth of the water
being then a little more than 200 fathoms.
At eight o'clock on the morning of the 9th we had exhausted the
deck coil in the after part of the ship, having paid out 120 miles.
The change to the coil between decks forward was safely made. By
noon we had laid 136 miles of cable, the Niagara having reached
lat. 52°, 11´ 40´´ N., long. 13° 0´ 20´´ W., and the depth of the
water having increased to 410 fathoms. In the evening the speed of
the vessel was raised to five knots. I had previously kept down the
rate at from three to four knots for the small cable, and two for
the heavy end next the shore, wishing to get the men and machinery
well at work prior to attaining the speed which I had intended
making. By midnight 189 miles of cable had been laid.
At four o'clock on the morning of the 10th the depth began to
increase rapidly from 550 to 1,750 fathoms in a distance of eight
miles. Up to this time a strain of 7 cwt. sufficed to keep the rate
of the cable near enough to that of the ship; but as the water
deepened the proportionate speed of the cable advanced, and it was
necessary to augment the pressure by degrees until at a depth of
1,700 fathoms the indicator showed a strain of 15 cwt., while the
cable and the ship were running five and a half and five knots
respectively.
At noon on the 10th we had paid out 255 miles of cable--the vessel
having made 214 miles from the shore--being then in lat. 52° 27´
50´´ N., long. 16° 15´ W. At this time we experienced an increasing
swell, followed later in the day by a strong breeze.
