Providence, R. I., Nov.28.
In the Journal of November 1st you invite me to describe the conditions under which the telephonic concerts performed in New York, for the benefit of audiences in Saratoga, Troy, and Albany, were overheard in Providence….During five evenings in the latter part of August performers stationed in the Western Union Building in New York sang or played into an Edison Musical Telephone, actuated by a powerful battery, and connected with one or other of the cities above…..
….transfer of electric wave motion from one wire to another may have taken place by induction….The music heard in Providence did not require or use one ten-thousandth, hardly one-hundred thousandth, of the electromotive force originally imparted to the Albany wire.
This startling conclusion suggests, first, the wonderful delicacy of the Bell telephone…and second, the as yet unimagined capacity of electricity to transport sound.
