9 . TRIUMPH OF SCIENCE AND EMPIRE. TRANS-ATLANTIC SERVICE AT THIRTY WORDS. PHENOMENAL INTERCEPTION. FROM MANILA TO NOVA SCOTIA. 'by teleoeath—PßESS ASSOCIATION—OOPTRIOnT. Reo. Oct. 18, 10.18 p.m.) Ottawa, October 18. Sir Wilfrid Laurier, Premier of Canada, has sent a Marconi message to tho English Press, stating that the wireless telegraphy installation has established a now bond botween Britain and Canada, and has achioved another triumph for the Empire and for science. ' The system is. not yet- open for private messages. " ' . Marconi experts at Morien, Nova Scotia, received on October 7 a message intended for some one in the Pacific, announcing the -arrivalof the American cruiser Philadelphia at Manila. Experts account for tho fact by the supposition that the tono at Manila must have been in perfect tune with that at Morien.. , , Lord Kelvin, Sir William Crookcs, Sir Oliver Lodge, and Professor Ayrton have warmly congratulated Signer Marconi. Marconi is transmitting Press messages between Clifden, Connemara, and Glaco Bay, Nova Scotia, averaging thirty words' a minute.'//. {.• DEATH WITHOUT CONTACT. ;■■■:■ New York, October 17 t , A wireless telegraph. operator was found dead in the sendingroom at Wollfleot, Massachusetts. '■.'"'.,■''■ The position of tho body showed that tho man had riot touched tho instruments. ' The indications point to'tho fact that he snecumbed to shock through the intensity of the electricity within tho room. ■ It'was announced -that when 11. undertook this new trans-Atlantic installation, that messages would transmitted fiom Clifden, Ireland, to Capo Breton, Canada and the ordinary rates would be 5d..a word,'plus land charges; Press/rate, 2W. a word,, plus land.charges. After tho Irish and .Canadian stations had been proved to ho of commercial value, the idea is to increase the power of the station at Cape Cod, and use it m connection with that at Poldhu, and tho proposals in regard' to inland schemes contemplated on tho other side of the Atlantic include the running of a wire from Cape Cod to New York. But interest for the time being is centred 'in the attempt to mako_ wireless telegraphy a successful;commercial rival -with the cable across tho Atlantic. ■ -. /• : In view of what is about to bo attempted, it is interesting (says the London "Tribune ) to' iremembor tho early experiments earned out by Mr. Marconi in telegraphing without wire's between tho Terrace' of tho Houso of ' Commons and St. Thomas's Hospital. Sinco that time wireless' telegraphy has revolutionised tho means of maritime communication, and tc-day the managers of London hotels aro no more surprised by a receipt.of a Marconigram from an American traveller "on board a liner in tho Atlantic than thoy are by tho receipt of a, sixpenny telegram from ■ tho provinces. Tho . estimato givon by tho company of the number of words passing betweon ships and the shoro on their wholb sendee -is. 1,280,000 annually. .'.,'■'■ '-.-','. , '.' ' :•■ ' Tho question of interceptions' and interruptions has been a big ono in tho history of tho invention Tho inventor of tho later systems, the Poulseni claims, to have overcome interruptions, and that "practically any number of stations within range of one another may now communicate without fear of mutual interference." Poulsen. claims .tp havo ! , invented a "singing arc" that will not mix with other "times."' A short timo ago, at Whitley' Bay, near tho mouth of the Tyno, tho warship Furious was commissioned to intorcopt or interrupt tho Poulsori wavos which woro flying across tho North Sea to Esbjorg, in Denmark. :' This she waa: unable to effect. Then tho representatives of the Amalgamated Radio-Tolcgraph Company, who own the Poulsen rights, told tho Furious the oxact wuve-length they wore employing. With ..this knowledge (which naturally would riot bo at an enemv's disposal in,'war tiiho), tho Furious, ompldying two or three times the electrical energy used by the Poulsen installation, was abla to cause trouble. , Tho interference, however, stoppod when the workers of tho new: system altered the wave-longth. Esbjerb was ablo to. pick up tho now wavo, though the Furious, using tho older wireless systom, was not ablo to : accomplish this.
