Communication after Adjournment

Fearing tlhat the remarks of some of the speakers may have left an erroneous impression as to the potential of telephone circuits carried on the poles of high-tension transmission lines, I desire to state that some measurements made by a Weston voltmeter between the conductors of a telephone circuit placed five feet below the conductors of a 25,000 volt overhead circuit and ground, showed tlhe potential to be only from 140 to 160 volts. Similar measurements on a telephone circuit three feet below a 10,000 volt line showed only about 95 volts to ground and, naturally, no difference of potential between the telephone conductors. It seems to me that the voltage of a telephone circuit given as 20,000 by Mr. Thomas cannot be such potential as would be indicated by a voltmeter or such as would cause particular damage, being, I assume, simply static potential. Referring to the suggestions made as to signaling in case of partial breakdown of the telephone system, it has occurred to me that as a relay to the telephone circuit, a system of wireless telegraphy could be installed without large expense, which might advantageouslv be used in transmitting signals in case of trouble with tlhe telephone circuit.
