The telephone system OF the United
States. with its millions Of miles OF
wires and conduts, will never have It's
commercial supremacy threatened by
the introduction of wireless telephony.
This assertion, set forth most EN-
phatically with an explanation OF the
nbvsical reasons behind il, is included
in the annual report Of the American
ToIephone and Telegraph Company,
made public Yesterday. 1t Is intended
10 reassure shareholders OF the Ben
system whose apprehensions have oeen
aroused By reports of successful wire
less projection of the human voice over
thousands Of miles OF land and water
Wireless telephony's value. says the
report, lies in its use 10 supplement-
rather than 70 supplant communication
over the wires. The report says:
"The announcement that wireless or
radio telephony was an accomplished
fact aroused much interest not only
among those who had possible uses LOT
il, but among those who desired 10
profit by II personally and financially
Many of our shareholders were sppre-
hensive as 10 the possibility OF its sup
planting the wire system. 10 answer

cular letter was given out explaining
the scope and uses OF the radio tele-
phone, and also saying that whatever
its future might be that future would
be as a part of the Bell system.
Will Not Displace Wire System.
"The circular was full and explicit
and recent developments do not IN any
degree change il. One ampiihcatlon
which will possibly make 1t clearer IS:
At the transmitting station the power
used depends entirely on and increases
rapidly with distance 20 be covered
For very long distances the power need
ed is considerable. The vibrations
transmitted have great amplitude vol,
ume and intensity. The intensity and
volume Of these vibrations as they pass
outward and onward, diminish rapidly
in every respect except as TO definite
ness. At the distant receiving station
they are very faint, but however faint,
providing the static conditions permit
and there are no artificial electrical
disturbance, they can be picked up and
transferred to a receiving instrument,
or TO a land wire, 10 be transmitted
further.
"If however. the radio receiving and
transmitting stations we're at the same
point, as they are on land lines, so long
as transmission was going on, creating
artificial electrical disturbances Of
great intensity. these receiving or IN
coming radio vibrations would be en-
tirely destroyed by the intensity and
volume Of the outgoing vibrations.
Conversation such as Is carried on
over land lines is only possible by hav-
ing the radio receiving station stu
ated at a place free from artificial cleo
trical disturbances, miles distant from,
and connected by wires with, the
transmitting station. In this way the
radio incoming vibration could be
picked up. transferred to wire and thus
transmitted TO the person converslng
ut the transmitting station.

wireless ever take the place Of wire
systems in the transmission of speech 2
so far as any present knowledge or
any present indications govern, the
answer may be an emphatic mo-"
So close has been the cooperation, the
