1897 - Wireless Telegraphy - Marconi - Invention Tested at Lavernock - The postal authorities of the country have evidently faith in the possibilities of the Marconi system of telegraphing without wires, and the Italian inventor (G. Marconi) has reason to feel proud of the success of the demonstrations, so far as they have yet been carried out. M. Marconi, as was reported the other day, successfully carried out on Salisbury Plain a series of experiments with a couple of balloons attached by wires to the ground.

For several days past he has been engaged in conducting experiments at Lavernock Point, near Cardiff, in testing the effective working of his system of telegraphing without wires between the mainland and the Flat Holm, and the trials have been witnessed by Mr. Preece, engineer-in-chief of the General Post Office; Mr. Gavey (late of Cardiff), now second engineer in London; Mr. Fardo, Cardiff postmaster, and other officials of the department.

For the purposes of the experiments. Mr. Williams (of the engineering department, Cardiff). fixed upon Lavernock Point a pole 120 feet high, with a zinc cylinder at the summit, 5ft. 6in. by 4ft., insulated from the Flat Holm and Brean Down.

The experiments on Tuesday were not so successful as might have been desired, but on Wednesday and Thursday the results were most satisfactory.

On Friday afternoon there was a semi-public demonstration, when the system was explained in miniature, a transmitter facing a receiver at a distance of some twenty yards. - Weekly Mail [067] [361] 22nd May 1897.
