Wireless Telegraphy

WIRELESS TELEGRAPHY

EXPERIMENTS AT THE UNIVERSITY PROVE SUCCESSFUL.

Prof. Carhart and Dr. Trowbridge Entertained the Legislative Visitors With it Yesterday.

Among the interesting experiments tried Friday for the amusement or instruction of the legislature was one by Prof. H. S. Carhart and Dr. Augustus Trowbridge at the physical laboratory. It was an exhibition of wireless telegraphy. Signals were sent through doors and partitions walls the whole length of the laboratory between two absolutely disconnected points. Dr, Trowbridge says that the method would work as well between the campus and the hospitals as for a few hundred feet in the laboratory. In fact there was no limit to the distance excepting that caused by the curvature of the earth and signals could be sent between two towers any distance apart so long as the curvature of the earth did not intervene. The apparatus used for the experiments yesterday, which proved highly successful, were made from newspaper descriptions of similar experiments in Washington very recently. This kind .of telegraphy will be most useful on water and will prove of more value to Michigan than to most of the other states. The experiment impressed upon the minds of the legislators that the university faculty were alive to all the latest discoveries in science.
