More about this marker. “Thomas G. Watson” in the inscription seems to be a typo for Thomas A. Watson.
 
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.”
