Center Of the World is a Tower
That Narrowly Escaped
Being Torn Down.

PARIS, Oct 20. The famous
Ethel Tower OF Paris, the highest
steel structure OF its kind in the
world, was about to be torn down
several years ago on account of its
iselessness. To-day ii is regarded
as one OF Frances most valuable
because OF the Eiffel Tower, has be-
come the wireless center of the
world.
Underneath the Champ de Mars,
In which the tower stands, a vast
jsubterranean wireless plant has been
CONSTRUCTED Its presence is scarce
ly suspected by the passer-by, for its
! only entrance is little more than a
trap-door in the ground, partly CON
lcealed by a clump OF trees. But
should he attempt to approach too
near the little iron staircase leading
underground, he will find his way
barred by soldiers.
below ground, amid maze of
passages, gigantic machines and a
continual cracking and uashing of
the wireless. corps of military en-
Igineers and electrical experts are
working day and night to perfect in

messages in wartime may depend
Frances victory or defeat, and on
which also win depend the adequate
cooperation OF the allied army OF
Russia. 1t was in his Laboratory
here that Prof. Henri AbeIham, or
the Sorbonne, talked to-day of what
his work as a member of the French
Wireless Mission sent by the COVER
ment to Washington, viii he. PROT
essor Aberham Will not Join his col
! leagues until late in October.
During our work at rl1ngtcn
last spring" said he, I'VE succeeded
in cooperation with our American
associates in establishing the rela-
Hive time of Washington and Paris
within the tenth of a second. Since
then we have been able to improve
greatly the receiving and recording
or wireless messages. we expect
now to establish the time of Wash
ington within the hundredth OF u
second, and as a part OF this result
the longitude OF Washington as re-
lated 10 Paris. France will later
send missions to the other principal
nations with the obiec of estab-
] fishing similar accuracy in the
relative times. Once this work is
accomplished the world will receive
time signals from Eiffel Tower and
win be able TO register them within
1.-THE hundredth of a second.
This effort for accuracy 20 with
in the hundredth of second has
required a tremendous improvement
lin the wireless apparatus and a great
advance in clock-making. Two OF
the most important pieces of the
equipment which we shall take to
America willpbe chronometers OF
such extremeo precision that after
ibeing set before leaving France they
are relied upon not to vary appreci-
ably during the whole of our time in
/ America.
siNe shall use photography in
registering Eiffel Tower signals for
fixing the exact longitude of Wash
ington. We arrive easily at an ae-
curacy of hundredth part of sec
ond by means of film revolving at
a fixed rate of speed and a luminous
spot Influenced by the wireless mes
sage. In registering the speed of
radio waves i have succeeded in di-
viding the second into 10000 parts
Experiences so far on the speed of
wireless waves tend to, show that
they travel at the same speed as
light, from which we make the inn
portant deduction that they are the
same thing"
