Plan to Prevent shipwrecks by
Wireless Signals.
HIGHLY PRAISED BY sAvANTs.

Frenchnan Proposes to Communicate
With Ships In All Seas From Paris
Eiffel Tower-To Tell Exact Longi-
tude Without Observations by Sun.
If the proposal presented to the
French Academy of Sciences at Paris
a few days ago by Bouquet de La
Grye be adopted, the Eiffel tower will
play such an important role in the
worlds shipping that wrecks through
miscalculation of longitude will here
after be rendered impossible
The yenerab Bile sayant. according to
wireless telegraph dispatch from Paris
to the New York Times, purposes to
equip the tower so that it can send the
exact time according to the meridian
of either Paris or Greenwich to every
ship in the world equipped with wire
less telegraphy.
He says that wireless plant of suf-
fcient force can be established to send
world. By prearranged signal either
noon or midnight would be indicated,
and ships would thus be able to regu-
late their own chronomete.s and learn
the exact longitude without taking OBJ
servations by the sun.
The proposal has already been ac-
copied in principle. and experiments

Atlantic and the Mediterranean It is
purposed to send the hour of midnight
according to Paris time, this being
preferable to noon owing to the alb
sence of local disturbances.
Among those who applauded the pro-
posal were Simon Newcomb, the emf.
nent astronomer of Washington, and
Alexander Agassiz of Cambridge. Mass.
Both were enthusiastic in praise Of the
plan and said that undoubtedly it
would receive the support of officials
and scientists in the United States.
Experiments are also now in progress
| with wireless telephony apparatus
on the Eiffel tower. The results Of
these experiments are thus far inde-
cisive, but important results are hoped
for in the near future.
The tower continues to furnish the
means Of rapid and sure wireless COM
munication between the government
and the army in Morocco. Should La
Grye's proposal be put into execution,
however, it is probable that new
| wireless post will be installed by the
French government on some lofty
mountain peak, possibly In the Canary
/ islands.

are number of rough sheds composed
OF boards. The few visitors who are
allowed to enter the Enclosure find
within the sheds apparatus similar to
that which is installed on Long Island
sound steamers for the purpose of
maintaining wireless communication
with the shore. But of course every
thing is on a much larger scale-the
condenser is a huge thing and the coil
of wire for resistance is gigantic-al-

sound steamers, and the man who

catch the faintest vibrations produced
by the Hertzian waves flowing from
the masthead Of the cruiser Kleber,
hundreds of miles away to the south,

frigate with force of 10000 volts, but

to perceive them when they reach the
