New Use for Telephone.

According to information from a reliable source, experiments conducted on the Canadian government railroads with a telephone apparatus that permits verbal messages to be transmitted to and from moving trains have met with highly gratifying re-

suits. Standard equipment is used and no difficulty has been encountered in getting distinct‘tones. Connection between the instrument and rail is made through the car wheels. Control of the system differs in no respect from ordinary telephone operation, and artificial amplifiers requiring adjustment are not employed. The invention makes it possible for connections to be made between the train Instrument and that of any regular telephone subscriber.— Popular Mechanics Magazine.
