“Why, it would go to the bottom, of course,” replied Smith, “and several hearts would break along with it. You see these two gentlemen conversing near the companion-hatch?”

“Yes.”

“One is the chief of the electricians; the other the chief of the engineers. Their hearts would probably break, for their position is awfully responsible. Then my heart would break, I know, for I feel it swelling at the horrible suggestion; and your heart would break, Robin, I think, for you are a sympathetic donkey, and couldn’t help yourself. Then you see that stout man on the bridge—that’s Captain Anderson—well, his heart would—no—perhaps it wouldn’t, for he’s a sailor, and you know a sailor’s heart is too tough to break, but it would get a pretty stiff wrench. And you see that gentleman looking at the paying-out gear so earnestly?”

“What—Cyrus Field?” said Robin.

“Yes; well, his heart and the Atlantic Cable are united, so as a matter of course the two would snap together.”

Now, while Smith and his young assistant were conversing thus facetio-scientifically, the electricians on duty in the testing-room were watching with silent intensity the indications on their instruments. Suddenly, at 3:15 a.m., when exactly eighty-four miles of cable had been laid out, he who observed the galvanometer saw the speck of light glide to the end of the scale, and vanish!

If a speck of fire had been seen to glide through the key-hole of the powder-magazine it could scarcely have created greater consternation than did the disappearance of that light! The commotion in the testing-room spread instantly to every part of the ship; the whole staff of electricians was at once roused, and soon afterwards the engines of the Great Eastern were slowed and stopped, while, with bated breath and anxious looks, men whispered to each other that there was “a fault in the cable.”

A fault! If the cable had committed a mortal sin they could scarcely have looked more horrified. Nevertheless there was ground for anxiety, for this fault, as in moral faults, indicated something that might end in destruction.

After testing the cable for some time by signalling to the shore, Monsieur de Sauty concluded that the fault was of a serious character, and orders were at once given to prepare the picking-up apparatus at the bow for the purpose of drawing the cable back into the ship until the defective portion should be reached and cut out.

“O what a pity!” sighed Robin, when he understood what was going to be done, and the feeling, if not the words, was shared by every one on board with more or less intelligence and intensity; but there were veterans of submarine telegraphy who spoke encouragingly and treated the incident as a comparatively small matter.
