Her immense hull was fitted with three iron tanks for the reception of 2,300 miles of cable, and her decks furnished with the paying-out gear. The Great Eastern took on board seven or eight thousand tons of coal to feed her fires, a prodigious quantity of stores, and a multitude of live stock which turned her decks into a farmyard. The marvellous development of telegraphy within the last generation has called into existence a great variety of receiving instruments, each admirable in its way. The needle is thus prevented from idly swinging about at each deflection, and the separate signals are rendered abrupt and 'dead beat,' as it is called. The message (in Morse code) was typed onto a piece of perforated tape using a keyboard-like device called the 'Stick Punch'. At 9 a.m. a message from England cited these words from a leading article in the current Times: 'It is a great work, a glory to our age and nation, and the men who have achieved it deserve to be honoured among the benefactors of their race.' 'Treaty of peace signed between Prussia and Austria.' The shore end was landed during the day by the Medway; and Captain Anderson, with the officers of the telegraph fleet, went in a body to the church to return thanks for the success of the expedition.

These waves, encroaching upon each other, will coalesce at their bases; but if the crests remain separate, the delicate decipherer at the other end will take cognisance of them and make them known to the eye as the distinct signals of the message. In overland lines the current traverses the wire suddenly, like a bullet, and at its full strength, so that if the current be sufficiently strong these instruments will be worked at once, and no time will be lost. However, unlike armored cables, metal-clad cables feature a full-size designated ground wire, while armored cables rely on a combination of the metal jacket and a thin wire or strip for grounding. This is owing to the phenomenon of induction, very important in submarine cables, but almost entirely absent in land lines. In submarine cables, as is well known, the copper wire which conveys the current is insulated from the sea-water by an envelope, usually of gutta-percha. Now the electricity sent into this wire induces electricity of an opposite kind to itself in the sea-water outside, and the attraction set up between these two kinds 'holds back' the current in the wire, and retards its passage to the receiving station.

In the electrical industry, "wire" and "cable" are often used to indicate the same thing. Profiting by these aids, an improved type of cable was designed. Underground Feeder (UF) is a type of nonmetallic cable designed for wet locations and direct burial in the ground. The merit of this receiving instrument is, that it indicates with extreme sensibility all the variations of the current in the cable, so that, instead of having to wait until each signal wave sent into the cable has travelled to the receiving end before sending another, a series of waves may be sent after each other in rapid succession. It consists of a very long fine coil of silk-covered copper wire, and in the heart of the coil, within a little air-chamber, a small round mirror, having four tiny magnets cemented to its back, is hung, by a single fibre of floss silk no thicker than a spider's line. Chatterton's compound, which is impervious to water, then covered with four layers of gutta-percha alternating with four thin layers of the compound cementing the whole, and bringing the weight of the insulator to 400 lbs.

At 5.30 p.m. on Sunday, July 23, amidst the firing of cannon and the cheers of the telegraph fleet, she started on her voyage at a speed of about four knots an hour. Once he had the scale model, he started on a full-size replica. On July 7, 1866, the William Cory laid the shore end at Valentia, and on Friday, July 13, about 3 p.m., the Great Eastern started paying-out once more. The back of Mack's truck is McQueen's luxurious bachelor pad, and it's fully loaded with the best in fiber optics, TVs, massage chairs, and more. The Great Eastern steamed back to England, where the indomitable Mr. Field issued another prospectus, and formed the Anglo-American Telegraph Company, with a capital of £600,000, to lay a new cable and complete the broken one. In 1837, Davy invented the much more practical metallic make-and-break relay which became the relay of choice in telegraph systems and a key component for periodically renewing weak signals. More faults of the kind were discovered, and as they always happened in the same watch, there was a suspicion of foul play. About 80 U.S. planes were lost on the return when they ran out of gas and ditched or crashed, but more than half of the crew members were rescued.
