Long Distance Telephone.
A WONDERFUL INVENTION.
[By Telegraph.] (Mail Steamer at Auokland.)
Much intorest is roused in a patent which makes telephoning long distances simple. Tho American Telephone and Telegraph Company has bought the patents of Dr. H. L. Pupin, of Columbia College. Tho right covers the. art of ocean telephoning, and includes devices for sending messages over any length of land linos. It has been given out that tho price paid was two hundred thousand dollars, with an annuity of seven thousand five hundred dollars additional. The new method permits the use of conductors of relatively smaller diameter, covored with insulating wire of moderate thickness, thus much lessening tho expense formerly necessary in the construction of long under-ground circuits. Tho plan for a Trans-Atlantic cable shows inductanco coils to be placed at proper intervals, permitting telephonic conversation to be heard across the Atlantic.
