Marvels of the Wire.

It is not widely known that at tho present time, between all important telephone centers of the United States, while tbe trunk wires are being used for transmitting speech, there are being sent over them simultaneously telegraphic messages without producing any interruption of tbe spoken words. Were it not for immutable laws of nature,which cannot be varied by man or corporation, you might, by listening, take off tbe telegraphic message thus traversing these very conductors. What a tantalizing prospect for the wire tapper! Although these telegraphic Impulses actually traverse the coil of wire in the telephone at your ear and actually speed along tbe identical copper conductor at tbat time conveying tbe voice currents, you hear neither dot nor dash of the telegrapblo message.—Leslie’s Weekly.
