The Story of the Atlantic Telegraph

This was an operation which could not be done with speed. With all the men who could be employed, they coiled on board only about two miles an hour, or twenty miles a day--at which rate it would take some five months. The work began on the nineteenth of January, early in the morning, and continued till June, before all was safely stowed on board. The Great Eastern herself had been fitted up to receive her enormous burden. It was an object to stow the cable in as few coils as possible. Yet it could not be all piled in one mass. Such a dead weight in the centre of the ship would cause her to roll fearfully. If coiled in one circle, it was computed that it would nearly fill Astley's theatre from the floor of the circus to the roof--making a pile fifty-eight feet wide and sixty feet high. To distribute this enormous bulk and weight, it was disposed in three tanks--one aft, one amidships, and one forward. The latter, from the shape of the ship, was a little smaller than the others, and held only six hundred and thirty-three miles of cable, while the two former held a little over eight hundred each. All were made of thick wrought-iron plates, and water-tight, so that the cable could be kept under water till it was immersed in the sea.
