WONDERS OF WIRELESS.

GREAT INVENTION 1 PERFECTED. "SIGNPOSTS" OP THE AIR. Of the many developments in wireless which Mr. Godrey <3. Isaacs revealed when lie was the principal guest at the Aldwycli Club luncheon, the moat wonderful is a new transmitter which projects into the air a wide divergent beam like a searchlight, without the llglit. These beams will convey to the man in the skies the name of the place he is passing over. He receives the signal, "This is Guildford," and he will continue to receive that signal so long as he is over Guildford and no longer. If he be passing over Windsor Forest ho will be told "This is Windsor Forest," and if he comes to his aerodrome the beam signals, "This is Hendon aerodrome."

In that way, said Mr. Isaacs, one of the greatest dangers to pilots in fog and in darkness will have been disposed of. [t wanted but little imagination to see that a little while hence some thousands, tens of thousands of names would be projected into the skies so that, whatever part of the world the aeroplane may travel, the passenger iB being automatically told where he is. It will be as easy to tell in the skies where you are as to see where you are when travelling in a railway train. Similarly, these beams can be equipped to lightships or buoys in fixed and defined so that when one passes over the seas one may know exactly where one is.

Dealing with other developments of wireless, Mr. Isaacs said that a passenger travelling across the Atlantic by boat would'never again.be out of touch with one or other of two coasts. Ships would in future be able to telephone and telegraph cither to ships at sea or to the coast without any possibility of interference. It would also bo possible to equip a vessel with aa apparatus which would givf it its exact position in dense fogs. It would not only be able to ascertain the approach of another ship, but it would also learn approximately and near enough far its purpose the distance at' that ship. In the same way, the whole coastline could be equipped with apparatus which would give to a ship at sea the approximate distance of the coast and its position. There was a simple means by wireless of communicating from airships or aeroplanes with other machines, with ships at sea, and with the land. And there was also the wireless direction finder, which enabled the pilot to ascertain approximately where he was.

As for the land, there was no reason why we should not have wireless teleh and telephone services between all the centres in the country.. There wag a great advance in wireless telephony, indeed, he regarded it as an epochmaking invention. - The message transmitted could be heard only by those by whom it was intended to be heard, without possibility of "tapping" or interruption.

Mr. Godfrey Isaacs told a pres9' representative that the wireless transmitter from earth to airmen, signalling the name of the place, would-, be put into practice almost immediately.
