All now went well till Saturday, the twenty-ninth, when a little after noon there was again a cry from the ship, as if once more the cable were wounded and in pain. This time the fault was more serious than before. The electricians looked very grave, for they had struck "dead earth," that is, the insulation was completely destroyed, and the electric current was escaping into the sea. As the fault had gone overboard, it was necessary to reverse their course, and haul in till the defective part was brought up from the bottom. This time it was more difficult, for they were in water two miles deep. Still the cable yielded slowly to the iron hands that drew it upward; and after working all the afternoon, about ten o'clock at night they got the fault on board. The wounded limb was at once amputated, and joining the parts that were whole, the cable was made new and strong again. Thus ended a day of anxiety. The next morning, which was the second Sabbath at sea, was welcomed with a grateful feeling after the suspense of the last twenty-four hours. On Monday, the miles of cable that had been hauled up, and which were lying in huge piles upon the deck, were subjected to a rigid examination, to find out where the fault lay. This was soon apparent. Near the end was found a piece of wire thrust through its very heart, as if it had been driven into it. All looked black when this was discovered, for at once it excited suspicions of design. It was remarked that the same gang of workmen were in the tank as at the time of the first fault. Mr. Canning sent for the men, and showing them the cable pierced through with the wire, asked them how it occurred. Every man replied that _it must have been done by design_, even though they accused themselves, as this implied that there was a traitor among them. It seemed hard to believe that any one could be guilty of such devilish malignity. Yet such a thing had been done before in a cable laid in the North Sea, where the insulation was destroyed by a nail driven into it. The man was afterward arrested, and confessed that he had been hired to do it by a rival company. The matter was the subject of a long investigation in the English courts. In the present case there were many motives which might prompt to such an act. The fall in the stock on the London Exchange, caused by a loss of the cable, could hardly be less than half a million sterling. Here was a temptation such as betrays bold, bad men into crime. However, as it was impossible to fix the deed on any one, nothing was proved, and there only remained a painful suspicion of treachery. Against this it was their duty to guard. Therefore it was agreed that the gentlemen on board should take turns in keeping watch in the tank. It was very unpleasant to Mr. Canning thus to set a watch on men, many of whom had been with him in his former cable-laying expeditions, but the best of them admitted the necessity of
