Two and a half octaves above these numerically, i.e. at about the twentieth octave, we reach the frequency of Electro-Magnetic Rills, used by the Marconi System of wireless telegraphy, which pulsate at about 950,000 per second, and have a wave-length of something like 1000 feet.
It was 12:30 o'clock on the American side of the ocean, and Marconi had ordered his operator in far-off Poldhu, two thousand watery miles away, to begin signalling the letter "S" three dots of the Morse code, three flashes of the bluish sparks at that corresponding hour.
He was successful whereas Nikolis went to the Ministry of Posts & Telegraphs where he ended up as Director-General many years later. The MARCONI COMPANY of England had built an impressive wireless station for the Greek Royal Navy at Votanikos, a suburb of Athens. There was a transmitter which operated on 600 metres and a larger one on long waves above 2,000 metres which used the callsign SXA.
America to-day, on the face of the earth and in the hearts of men, is a new democracy, as new as Radium, Copernicus, the Wireless Telegraph, as new and just beginning to be noticed and guessed at as Jesus Christ! Copernicus, Marconi, Wilbur Wright, and Christianity have turned men's hearts outward. Men live for the first time in a wide daily consciousness of one another.
Space is all a-quiver with waves of radiant energy. We vibrate in sympathy with a few strings here and there with the tiny X-rays, actinic rays, light waves, heat waves, and the huge electromagnetic waves of Hertz and Marconi; but there are great spaces, numberless radiations, to which we are stone deaf. Some day, a thousand years hence, we shall know the full sweep of this magnificent harmony.
Of course, the use of a cipher code would secure the secrecy of a message, but Marconi was looking for a mechanical device that would make it impossible for any but the station to which the message was sent to receive it.
It was an article in an electrical journal describing the properties of the "Hertzian waves" that suggested to young Marconi the possibility of sending messages from one place to another without wires.
Stephen's tower streaming upwards into the misty London night and the great wet quadrangle of New Palace Yard, from which the hansom cabs of my first experiences were ousted more and more by taxicabs as the second Parliament of King Edward the Seventh aged; I think of the Admiralty and War office with their tall Marconi masts sending out invisible threads of direction to the armies in the camps, to great fleets about the world.
"Our Marconi operator, whose unceasing efforts for many hours deserve the greatest possible praise, was unable at this time to get any reply to the urgent inquiries he was sending out, and he feared the worst. "At last a blue flare was observed, to which we replied with a rocket. Day was just dawning when we observed a boat in the distance.
Nor would he even look at it. He would not face the logical sequence of his dogmatic unbelief. Only a brave man dare express all he believes. Now it is well known that every advance in scientific knowledge is greeted with mocking laughter. We know the jeers with which even clever men greeted the Marconi claims.
