MORE MARVELS OF WIRELESS

TALK WITH AN AEROPLANE. "Every morning in the cabin of my Electra yacht, in the Bay of Naples, 2260 nautical miles from Loudon, I listen to a couple of columns of the latest news from tho Fleet Street newspapers* read to mo hy wireless telephony direct from mv stuff'in England." So said Senator Marconi on August .18 1 to a correspondent of the London "Daily I Chronicle." ' Marconi, hopes to complete by Nm ember the series) of special experiments lie began last May. and by that tune to have perfected easy talking from London to Egypt, and perhaps beyond. Be has two helpers only—Mr. I'aine, the transmitter, and the engineer, Albre -both of them Londoners. All Hires are spending much of jthcic lime iu nn endeavour to find means .of pi wonting messages being intercepted. "I shall not be satisfied," «nid llarconi, "until our radio-goniometric apparatus can pick up any single vessel which is known to be speeding within a given radius towards a_ given port, so that a «hip in distress may no longer need to send forth its appeal wildly and hysterically to all points of tho compass:, nor until communications intended for direct dispatch to a particular town or a particular newspaper arc safo and confidential as a sealed letter." When he has concluded his experiments. Marconi will embody the r.esults in a monograph. "The Times" gives details of an interesting development in the use of wireless telephony for business purposes, a city, firm telephoning instructions to an air pilot, whilst in flight, from on ordinary desk telephono in their business premises, The aeroplane, the City of London, had started from Croydon, and was well on its way, Pilot Chattaway being entrusted with several messages by Messrs. Instone, when Mr. Samuel Instone, one of the directors, wis- desirous of sending additional instructions to tho pilot respecting the position of some coal in Prance. He immediately telephoned from hi office in Billiter Street to the Croydon aerodrome, and having expressed his anxiety to reach the pilot, was at once connected un with the Air Ministry wireless' .installation. Within a few seconds Piter his inquiry. "Instone, Vimy: is Cfiattaway there?" there caino a response from the pilot, and it long conversation followed. Tho additional instructions, were given by Mr. Instone, and on arriving in Paris the pilot discharged his commission, and within two hours a telegram was* received at Billiter Street, conveying the information which Mr. Instone" had sought.
