The Story of the Atlantic Telegraph

The process of detecting faults is too scientific to be detailed in these pages. We can only stand in silent wonder at the result, when we hear it stated by Mr. Varley, that the system of testing is brought to such a degree of perfection, that skilful electricians can point out minute faults with an unerring accuracy "even when they are so small that they would not weaken the signals through the Atlantic cable one millionth part!" Another marvellous result of science was the exact report obtained of the state of that portion of the cable now lying in the sea. The electricians at Valentia were daily experimenting on the line which lay stretched twelve hundred and thirteen miles on the bottom of the deep, and pronounced it intact. Not a fault could be found from one end to the other. As when a master of the organ runs his hands over the keys, and tells in an instant if it be in perfect tune, so did these skilful manipulators, fingering at the end of this mightier instrument, declare it to be in perfect tone, ready to whisper its harmonies through the seas. At the same time, the ten hundred and seventy miles of cable left on board the Great Eastern were pronounced as faultless as the day they had been shipped on board. With such conclusions of science to animate and inspire them, the great task of manufacturing nearly seventeen hundred miles of cable once more began. And while this work went on, the Great Eastern, that had done her part so well before, again opened her sides, and the mysterious cord was drawn into her vast, dark, silent womb, from which it was to issue only into the darker and more silent bosom of the deep.
