The History of Telegraph


   The idea of electrical communication seems to have begun as long ago as 1746, when about 200 monks at monastery in Paris arranged themselves in a line over a mile long, each holding ends of 25ft iron wires. [Crack IELTS with Rob] The abbot, also a scientist, discharged electrical shock. “This all sounds very silly, but is in fact extremely important because, firstly, they all said ‘ow’ which showed that you were sending a signal right along the line; and, secondly, they all said ‘ow’ at the same time, and that meant that you were sending the signal very quickly, “explains Tom Standage, author of the Victorian Internet and technology editor at the Economist. Given a more humane detection system, this could be a way of signaling over long distances.


   With wars in Europe and colonies beyond, such as signalling system was urgently needed. All sorts of electrical possibilities were proposed, some of them quite ridiculous. Two Englishmen, William Cooke and Charles Wheatstone came up with a system in which dials were made to point at different letters, but that involved five wires and would have been expensive to construct.


   Much simpler was that of an American, Samuel Morse, whose system only required a single wire to send a code of dots and dashes. [Crack IELTS with Rob] At first, it was imagined that only a few highly skilled encoders would be able to use it but it soon became clear that many people could become proficient in Morse code. A system of lines strung in telegraph poles began to spread in Europe and America.


   The next problem was to cross the sea. Britain, as an island with an empire, led the way. Any such cable had to be insulated and the first breakthrough came with the discovery that a rubber-like latex from a tropical tree on the Malay peninsula could do the trick. [Crack IELTS with Rob] It was called gutta percha. The first attempt at a cross channel cable came in 1850. With thin wire and thick installation, it floated and had to be weighed down with a lead pipe.


   It never worked well as the effect of water on its electrical properties was not understood, and it is reputed that a French fisherman hooked out a section and took it home as a strange new form of seaweed.


   The cable was too big for a single boat so two had to start in the middle of the Atlantic, join their cables and sail in opposite directions. Amazingly, they succeeded in 1858, and this enabled Queen Victoria to send a telegraph message to President Buchanan. [Crack IELTS with Rob] However, the 98-word message took more than 19 hours to send and a misguided attempt to increase the speed by increasing the voltage resulted in failure of the line a week later.


   By 1870, a submarine cable was heading towards Australia. It seemed likely that it would come ashore at the northern port of Darwin from where it might connect around the coast to Queensland and New South Wales. [Crack IELTS with Rob] South Australia realised it would miss out, and Charles Todd was determined that this should not happen and put in a courageous bid to run an overland telegraph line right across the heart of the Australian continent, a distance of 2,700 miles, through territory which had hardly even been explored.


   It was an undertaking more ambitious than spanning an ocean. Flocks of sheep had to be driven with the 400 workers to provide food. They needed horses and bullock carts and, for the parched interior, camels. In the north, tropical rains left the teams flooded. In the centre, it seemed that they would die of thirst. One critical section in the red heart of Australia involved finding a route through the McDonnell mountain range and then finding water on the other side.


   The water was not only essential for the construction team. There had to be telegraph repeater stations every few hundred miles to boost the signal and the staff obviously had to have a supply of water. [Crack IELTS with Rob] Just as one mapping team was about to give up and resort to drinking brackish water, some aboriginals took pity on them.


   Altogether, 40,000 telegraph poles were used in the Australian overland wire. Some were cut from trees. Where there no trees, or where termites ate the wood, steel poles were imported.


   On Thursday, August 22, 1872, the overland line was completed and the first messages could be sent across the continent; and within a few months, Australia was at last in direct contact with England via the submarine cable, too. [Crack IELTS with Rob] The line remained in service to bring news of the Japanese attack on Darwin in 1942.


   It could cost several pounds to send a message and it might take several hours for it to reach its destination on the other side of the globe, but the world never is the same again.


   Governments could be in touch with their colonies. Traders could send cargoes based on demand and the latest prices. Newspapers could publish news that had just happened and was not many months old.
