Eight Messages Over One Wire

It is said that after prolonged experiments in sending four telegraphic messages each way simultaneously over a single wire, the German government has accepted the octuple transmitter invented by the late Prof. Rowland of the Johns Hopkins University. Between 300 and 350 words per minute were transmitted with success and it is understood that the German government will introduce the Rowland system between Berlin, Hamburg, Cologne, Leipzig and Frankfort.
