Air Alarconi. in an address to Royal Society of Arts, on the results of the beam system of wireless experiments, declared that there was a comparative economy in capital in the cost ol stations equipped with this system. Only a small amount of electrical power was needed, and its capability of working at a very high speed should make it passible to bring about a substantial reduction in telegraphic development anywhere in the world, and was willing to lend money to the British Dominions, but the terms would be severe as compared with what the Colonies were accustomed to.

Referring to the telephone tests between Britain and Australia, he stilted a wave length of 92 metres was employed. The total power supplied by the valves was 29 kilowatts. Reflectors were not used at either end. The results were easily a record for the ratio of the distance to the wave length, Sydney being approximately 199 thousand wave lengths from Cornwall. He believed that it had Isceit proved conclusively that adequately designed reflectors would enormously increase the effective strength of the signals besides increasing the hours in which it would he possible to communicate with the most distant countries, and reducing the interference. Referring to the Argentine tests ho said ho had been advised that the signals were received at Buenos Aires with such regularity and extraordinary strength as to permit a service to he conducted at any speed. The Argentine authorities were of the. opinion that their station should he immediately equipped with the system, which ihey were confident was capable of handling more than double tbo truffle i i six hours that could be handled in 21 hours with the present super-power station.

Mr Marconi said lie was convinced that. by means of'these comparatively small stations, a far greater wordage could be transmitted daily between England and distant dominions that had been possible previously. It was planned to build a powerful and expensive station.
