lakes. Although the American Navy was
the first to utilize wireless telephony Il
since has been installed on many OF the
ships OF the italian Navy, while the navy
OF Great Britain is following the same
course with all possible speed.
Whnt Wireless Telephony Has Done.
Already, from the station which the
De Forest people installed at the
top OF the Einel Tower in Paris, tests
have been made which carried the hui
man voice clear and distinct to beyond
Marseilles, coo miles away. In this country
successful tests have been made for a
distance OF $50 miles, but when the new
station is completed in the hfty-second
story OF the huge Metropolitan Life
campanile in this city, 1t is confidently
| expected by the wireless telephone exc
perts that they can project the voice
much further than at the Paris tests. In
fact, the inventor, dc Forest, has de-
clared that within a short time he win be
able to send messages between these two
greatest stations so that the voice spoken
| In New York may be distinctly and i'm
medlatey heard In Paris.
When one considers that thirty years
ago the present wire telephone system
was laughed at as being nothing more
than a clever toy, and that Prof. Alex
ander Graham Bell nearly wore his heart
| and soul out trying to get the small
sum Of money needed TO construct his
small test line for three miles from Bost on
TO Somervllle, the suggestion OF wireless
talking from New York to Paris Is not
to be considered as a smile-provoking
proposition.
In establishing It's system OF wireless
telephony it already has been announced
by the Great Lakes Radio Telephone COM
pany OF Cleveland, which controls the De
Forest system for the territory In question,
that 1t win work in conjunction with all the
existing wire telephone systems, whether
Bell or independent. BY simple con
triyance the wire phone system can be
connected with the wireless system at
any OF the latter's central stations so
that a person located at a regular long
| distance telephone In New York, for in-
stance, can be connected through a wire-
less station at Cleveland and hold con-
versatlons with a business associate trav-
cling as a passenger on a steamer out
in the middle OF Lake Erie.
Each central wireless station will have
its apparatus attuned TO certain num-
her OF vibrations on the principle OF a
tuning fork. The attuning Of an in.
strument can he changed by a switch
Sust as the switchboard OF a central wire
tstatlon can be regulated by the Insertion
OF plugs. In this way when a Lake
steamer, for instance, desires to talk will
Cleveland, It's operator will throw tn,
switch TO the number OF vibrations callet
for by Cleveland. When the wire instru
lment on the steamer Is IN repose, II viii
drop back TO a certain specific number o.
vibrations so that II can he reached by
any central station calling its number
or by means OF an Aerephone automatic
signalling device, can be reached by any
station sending out storm signals In dark
ness or fog In this way each instru
ment can be so regulated that II car
either take up general calls from any
direction or only specific calls for III
own number, as might be desired.
