Waves Restored

Without the carrier wave and its twin sidewave the voice is dumb and useless. but at the receiving end the carrier wave and the other sideband are restored, modulation becomes possible, and the single side wave delivers its message without loss.
 The voice on its journey from New York travels by land wire to the Rocky Point radio transmitting station on Long Island, where it Is thrust across the S,550 air miles to Wroughton, England, where it again goes by land wire to London. The westward route carries the voice from London to the Rugby transmitting station over 2.290 air miles to Houlton, Maine.
 50 Years of Progress.
 Inauguration of the first trans Atlantic telephone service between New York and London today not only spans the blue Atlantic, but represents the extension in 50 years of the transmission of the human voice from a tiny wire 55 feet long to winged service capable of cov- ering 5000 miles or more of noun tains, sea and plain.
 Rapid Development.
 Less than a dozen years since New York talked over the telephone to San Francisco, a receiver taken down today in New York clicked in the ear of an auditor in London, $500 miles away.
 And with no further effort than ringing up" a suburb, bobbed- haired, short-skirted Metropolitan girl operator could have plugged in San Francisco, telephone company officials said.
 Today more than s5,000,000 worth of equipment was in use to carry the voice of President Clifford of the American Telephone & Telegraph company to the ear in London of Sir G. Evelyn P. Murray, secretary of the British general post office, in the opening conversation over the con- mercial service.
 Bells First Success.
 In 1876, when the struggling Bos- ton professor. Alexander Graham Bell, talked to his friend, Thomas Watson, over the 50-foot wire, strung across a Boston street, the equipment could have been pur- chased for the traditional song.
 Come here, MT. Watson" said Bell on the wire, T want you.'
 Then Bell had one wire. Today in the United States there are 17,O0O,- 900 telephones, and connecting New York and London are not only one 5000 meter circuit, but an emer- gency short-wave circuit using 22- meter frequency.
 short Wave Length.
 The utilization of the short wave, so much discussed as a long distance possibility, is said to be triumph for American engineers.
 Research for more than 10 years has been conducted by the labora- tories of the A. T. & T. company, it was said today.
 In the laboratories 5000 engineers are devising and revising methods and material
 Not A Discovery.
 The transmission of the voice across the water represents a mag nification of method rather than a discovery, for Bell, the inventor of the telephone was, in 1880, the first person to use and patent device for the projection of the voice over a ray of light.
 The radio waves exchanging the New York and London accents, diff fer from the light waves in that the radio waves are longer.
 It was not until the continent was spanned with wires, that the A. T. X T. Company turned to piercing the ether where wires could not be strung. It's first experiment of moment was when the company's engineers talked from Montauk Point, Long Island, to Wilmington, Delaware. Next came talk from Montauk Point to St. Simons Island off the southern coast of the United States.
 These experiments holstered the confidence of the engineers, and al though the World War interfered
