Remarkable Telephoning.
Philadelphia Inquirer. The Telephone Committee of the Trades League last night witnessed some very interesting experiments with a lately constructed by a resident of Darby. Thomas Martindale.Chairman of the Committee, conducted the party, and at the place of destination it was met by the Hon. Samuel Crother. For the purpose of the experiment a wire had been attached between two houses, about three-quarters of a mile apart. The two ends of which were fixed to ordinary looking telephone boxes with double ear drums. There was nothing to indicate anything unusual about the instrument. The first experiment, which, like the rest proved eminently successful was to talk between the two bouses, each man standing ten feet from the transmitter. Every word was heard just as distinctly as if both were iuthe room together and uot a mile apart. C Then from the same fli-tsnee the two men whispered, and stilt every word was hoard. This over, a small watch was set in motion and placed near the transmitter. Every tick was heard with remarkable clearness. After that a child’s organ was played about thirty yards from the phone,and every note was carried in waves across the wire and reproduced at the other end. Another pleasing experiment was con veyiog sound through’Half a do.en meu, which passed into the drum and could be heard by-tlie one holding it. The.drum was detached, and two men held tbe points of the wire, several others joined hands, two more held the two projecting pieces of metal where the points of wire are inserted, and another held the drum. As soon as the speaker at the opposite phone began, the sound waves were carried faultlessly through ea.h man and passed out to the drum. Five minuted’ conversation was kept up in this novel manner. The next experiment was calling of numbers from a distance of forty feet, and these numbers were repeated by the one at the other end. and then, finally, tbe drum was placed on the ta <lr, and the tuan opposite telephone repeated the names or those present. So delicate and yet so powerful is this instrument that though tbe parties sat at least five feet Itim the drum.
