Jules Verne: Twenty Thousand Leagues Under the Seas

SECOND PART CHAPTER 20: In Latitude 47 degrees 24' and Longitude 17 degrees 28' (continued)

Instead of continuing north, the Nautilus took an easterly heading, as if to go along this plateau on which the telegraph cable rests, where multiple soundings have given the contours of the terrain with the utmost accuracy.

It was on May 17, about 500 miles from Heart's Content and 2,800 meters down, that I spotted this cable lying on the seafloor. Conseil, whom I hadn't alerted, mistook it at first for a gigantic sea snake and was gearing up to classify it in his best manner. But I enlightened the fine lad and let him down gently by giving him various details on the laying of this cable.

The first cable was put down during the years 1857-1858; but after transmitting about 400 telegrams, it went dead. In 1863 engineers built a new cable that measured 3,400 kilometers, weighed 4,500 metric tons, and was shipped aboard the Great Eastern. This attempt also failed.

Now then, on May 25 while submerged to a depth of 3,836 meters, the Nautilus lay in precisely the locality where this second cable suffered the rupture that ruined the undertaking. It happened 638 miles from the coast of Ireland. At around two o'clock in the afternoon, all contact with Europe broke off. The electricians on board decided to cut the cable before fishing it up, and by eleven o'clock that evening they had retrieved the damaged part. They repaired the joint and its splice; then the cable was resubmerged. But a few days later it snapped again and couldn't be recovered from the ocean depths.

These Americans refused to give up. The daring Cyrus Field, who had risked his whole fortune to promote this undertaking, called for a new bond issue. It sold out immediately. Another cable was put down under better conditions. Its sheaves of conducting wire were insulated within a gutta-percha covering, which was protected by a padding of textile material enclosed in a metal sheath. The Great Eastern put back to sea on July 13, 1866.

The operation proceeded apace. Yet there was one hitch. As they gradually unrolled this third cable, the electricians observed on several occasions that someone had recently driven nails into it, trying to damage its core. Captain Anderson, his officers, and the engineers put their heads together, then posted a warning that if the culprit were detected, he would be thrown overboard without a trial. After that, these villainous attempts were not repeated.
