regiment equipped with the telephone
receivers. with only their rifles as aer-
ials, could advance mile and each
would be instantly in touch with the
commanding officer. No runners would
be needed. There could be no such thing
as a lost battalion" Men could be
equipped too with the sending apparatus

No high power is necessary TO op-

tenth of an ampere in this experiment
mere and the results you see are so
good that the voice carries as we'll as
on the usual wire telephone. The tele.
phone system uses about a fourth Of an
ampere.
Il am working on a new theory in
electricity, and in wireless. think the
accepted principle of the waves Is only
part of the story There is something
else. 1t is that something else that am
utilizing. There is no supplementary
current in this system as in the usual
wireless operation. There is no static
and no Interruption"
Mr.. Macfarlane is the inventor Of
another departure in telephone commu-
nication. He first devised the method of
telephoning to and from moving train
by using the rails and wheels as
wires The practicability of this sys-
tern has been demonstrated on the Can
adam Pacific Railroad The Reading
Railway here is installing the system
on four mile stretch of track between
Jenkintown and Tabor

Nothing new is used." he explained
