BEAM WIRELESS SYSTEM

BRITAIN TO AUSTRALIA t CONFIDENCE IN -FUTURE OF RADIO-TELEPHONY. (United Press Association.—Copyright.) LONDON, 10th. January. As a result of a'threo days-? test of ; the Australian beam systom during the weok-ond, the Marconi Company .maintained a speed of 300 words a minute. They are therefore dispensing with tho seven-day test, as was the ense with Canada, and will hand over tho system to tho Post Office on Wednesday for a week's test. If this is satisfactory, tho service will open immediately. It is understood that thero is no hope of a variation of tho decision, made 'at the time the contract was signed, that the charges will bo twothirds of tlTe cable rates.

It is understood also that Mr.; Marconi offored to begin wireless telephony tests to- Australia within the space of a fow weeks, but the Post Office wishes to concentrate on the perfection of wireless telegraphy first, also ■to profit by tho experience 'of the 'Complexities of telephony witli America. For instance, yesterday at >a trial with Ottawa the London speaker'swords came back as an echo in his ep,rs in a few seconds. The elimination of this, also the achievement of complete secrecy, aro problems to be solved. >

Tho records show that both South Africa and New Zealand heard talks with America, but isolated snatches of one voice only.

"Wo are confident that a year hence 'telephony to-Australia will v in operation as a commercial proposition. It may be erratic at times, but quite work: able at certain periods of the day. Wo think tho short -wave length will facilitate it. Furthermore, it is a hopeful sign that tho short wave service to Cairo goes on when tho trans-Atlan-tic "comploteiy fades out." " This was the opiniifi oxprcssed by a high official who is in daily touch with all experiments.
