Regarding First Long-Distance Phone Call. Coming just seven months after their first transmission of speech over a wire, this “long distance” experiment attracted wide notice. For example, on Nov. 18, 1876, the Arizona Citizen (Tucson, Arizona Territory) reprinted the report of a Boston paper: “Telephones were placed at either end of a telegraph line owned by th[e] Walworth Manufacturing Company, extending from their office in Boston to their factory in Cambridgeport, a distance of about two miles. The company’s battery, consisting of nine Daniels cells, was removed from the circuit and another of ten carbon elements substituted. Articulate conversation then took place through the wire. The sounds, at first faint and indistinct, became suddenly loud and intelligible. Mr. Bell in Boston and Mr. Watson in Cambridge took notes of what was said and heard, and the comparison of the two records shows that the transmission was almost perfectly accurate. Conversation was carried on for about half an hour, generally in an ordinary tone of voice, but often in whispers. The credit of this important discovery is due to Mr. Bell.”

2. Wikipedia entry for Long-Distance Calling. “On October 9, 1876, Alexander Graham Bell and Thomas A. Watson talked by telephone to each other over a two-mile (3 km) wire stretched between Cambridge and Boston. It was the first wire conversation ever held. Yesterday afternoon the same two men talked by telephone to each other over a 3,400-mile (5,500 km) wire between New York and San Francisco. Dr. Bell, the veteran inventor of the telephone, was in New York, and Mr. Watson, his former associate, was on the other side of the continent. They heard each other much more distinctly than they did in their first talk thirty-eight years ago.” Quoted from the New York Times January 26, 1915.
