Telephony Without Wires

System which Utilizes the Terrestrial Currents.

Boston Herald

In a little workshop in Philadelphia, a young inventor has devised and is fast perfecting a system of telephony whereby the human voice, as well as the signals of the Morse alphabet, is transmitted through earth and air without the use of wires.

A practical demonstration of wireless telephony was given last Tuesday and a company organized to exploit the system named after Prof. A. Frederick Collins, an electric engineer, formerly of Chicago, but now residing in Philadelphia.

The Collins plan is quite distinct from the Marconi system. It uses no coherer, which is the salient point of the Marconi system. This coherer is a very delicate device, that must be adjusted to the minutest nicety.
