WIRELESS TRIUMPH.

THE DEVELOPMENT OF THE DEAM SYSTEM.

[Archibald Hurd in "Straits, Times."]

With existing apparatus, the speed, it is claimed, is higher than that of any other long distance téle- graph service in the world, whether by wire, cable, or high-power long-wave wireless stations, and stations operated on this system are capable of handling all the traffic at present available between any two countries with ample margin for future Increase.

While this remarkable progress in transportation has been going on,, wireless telegraphy, owing parti- cularly to the genius of Senator Marconi, has been placed at the sex vice of the British peoples. When the first signals were sent through the ether, it was said that wireless. telegraphy would in time supersede the cable.

Owing to this latest achievement of Senator Marconi, it will in no, long time be possible for the most isolated communitles of the British Empire to keep in touch with the great centres of population in B manner which would have been re- garded as impossible a few years,

There is now every assurance that beam wireless will be adaptable to wireless telephony and there is also the possibility of superimposing commercial telephone channel upon high-speed telegraph services using the same aerial system, thus obviat Ing the cost of erecting separate stations for carrying out telephonic communications.

Two famous British pilots, Captain R. H. Macintosh and Lieut.-Colonel F. F. Minchin, are privately planning to conquer all Atlantic flying records for Bri- tain by flying from London to New York for the first time, re- fuelling there in eight hours, and flying straight back to Europe. They hope to be back over Europe within 80 hours of leaving Eng- land. They will take turns at piloting the machine, and will only remain in New York long enough to refuel and glance over the engine.
