Wireless Telegraphy 23 Carlo Alberto, which the Italian Government placed at the disposal of its distinguished son. From this vessel, in which Mr. Marconi sailed for Canada in October, 1902, signals were exchanged with the Cornish station throughout the voyage across the Atlantic up to 2,300 miles. A few weeks later Poldhu and Glace Bay were in wireless connection, and transatlantic wireless telegraphy became an estab- lished fact. During the spring of 1903 a regular service of American news messages was transmitted by wireless from Glace Bay by arrangement with the Times, and success was achieved, although it had to be suspended a little later owing to a breakdown at the Canadian station. Six months later another notable record was established, the Cunarder Lucania being in news communication with Poldhu during the entire crossing from New York to Liverpool. While the Poldhu station proved satisfactory it was subsequently decided to construct a new and more powerful station for transatlantic wireless upon the extreme western coast of Ireland. Clifden was selected as the most suitable site, and here the most modern and complete installation was carried out. To-day, while Poldhu is in operation, it is virtually reserved for the handling of messages between ship and shore, while that at Clifden is reserved for commercial and other messages between Great Britain and America. During the past few years wireless telegraphy has made enormous advances in all parts of the world. The Germans, no doubt somewhat piqued at Mar- coni’s success, developed an individual system known as the “ Telefunken,” the joint invention of Professor Slaby and Count Arco. But it was not until the first
