Two men-of-war, the Terrible and the Sphinx, had been appointed to accompany and aid the Great Eastern on her important mission. A gun was fired and signals were made to acquaint these with what had occurred while the fires were being got up in the boilers of the picking-up machinery.
Electricians as well as doctors differ, it would seem, among themselves, for despite their skill and experience there was great difference of opinion in the minds of those on board the big ship as to the place where the fault lay. Some thought it was near the shore, and probably at the splice of the shore-end with the main cable. Others calculated, from the indications given by the tests, that it was perhaps twenty or forty or sixty miles astern. One of the scientific gentlemen held that it was not very far from the ship, while another gentleman, who was said to be much experienced in “fault”-finding, asserted that it was not more than nine or ten miles astern.
While the doctors were thus differing, the practical engineers were busy making the needful preparations for picking-up—an operation involving great risk of breaking the cable, and requiring the utmost delicacy of treatment, as may be easily understood, for, while the cable is being payed out the strain on it is comparatively small, whereas when it is being picked up, there is not only the extra strain caused by stoppage, and afterwards by hauling in, but there is the risk of sudden risings of the ship’s stern on the ocean swell, which might at any moment snap the thin line like a piece of packthread.
The first difficulty and the great danger was to pass the cable from the stern to the bow, and to turn the ship round, so as to enable them to steam up to the cable while hauling it in. Iron chains were lashed firmly to the cable at the stern, and secured to a wire-rope carried round the outside of the ship to the picking-up apparatus at the bows. The cable was down in 400 fathoms of water when the paying-out ceased, and nice management was required to keep the ship steady, as she had now no steerage-way; and oh! with what intense interest and curiosity and wonder did Robin Wright regard the varied and wonderful mechanical appliances with which the whole affair was accomplished!
Then the cable was cut, and, with its shackles and chains, allowed to go plump into the sea. Robin’s heart and soul seemed to go along with it, for, not expecting the event, he fancied it was lost for ever.
“Gone!” he exclaimed, with a look of horror.
“Not quite,” said Jim Slagg, who stood at Robin’s elbow regarding the operations with a quiet look of intelligence. “Don’t you see, Robin, that a wire-rope fit a’most to hold the big ship herself is holdin’ on to it.”
“Of course; how stupid I am!” said Robin, with a great sigh of relief; “I see it now, going round to the bows.”
At first the rope was let run, to ease the strain while the ship swung round; then it was brought in over the pulley at the bow, the paddles moved, and the return towards Ireland was begun. The strain, although great, was far from the breaking-point, but the speed was very slow—not more than a mile an hour being considered safe in the process of picking-up.
“Patience, Robin,” observed Mr Smith, as he passed on his way to the cabin, “is a virtue much needed in the laying of cables. We have now commenced a voyage at the rate of one mile an hour, which will not terminate till we get back to Owld Ireland, unless we find the fault.”
