Editor's Notes
Enclosed is a circular that we are issuing in realtion to the Edison Phonoplex Sytem of Telegraphy. Mr.Edison has just got to the purpose of duplicating way wires, putting way circuits on quadruplex and duplex wires. We are placing it East here with the railroad companies, more particularly for use on their railroad wires in the conduct of their own buisness. Even if you cannot give me information I desire, I know the circular with interest you.
