to make their way through fog or storm
to safety.
I'm England the lighthouses are already
using wireless telegraphy. My plan is to
have all ships equipped with signaling
machines and de1ectors 1t will then be
possible to send signaling currents all in
one direction instead of broadcast, as is
now done The defeCtors will be revolved
about the mast, and as the currents reach
the point from which they are sent to the
receiver an indicator will ring and the
pilot may steer his vessel along a safe
course, being guided by signals from
shore"
Signor Marconi was asked whether he
had any knowledge of the telediagraph in
vention which is being used by the Her
aid to send and receive pictures by wire
"Oh, yes" he said, II have given it
some study, and it is in it's way Won
der Like wireless telegraphy, it has yet
to be brought to it's fullest perfection, but
even now it is capable of great practical
results"
Gould wireless telegraphy be applied
to the sending of pictures?"
Certainly. Given time sufficient for the
installation of plants, l would guarantee
to transmit through the air picture per-
feet in outlines of the finish between the
Shamrock and Columbia"
WASHINGTON, Oct. SIT is under
stood that the cruiser New York and bat
tleship Texas will be equipped with in
~truments and a shore station will be es-
tablishced at Atlantic Highlands Ex-
periments have already been made by the
life-saving service, but the result has not
been decisive If satisfactory, Hfe-saving
stations and lighthouses will probably be
equipped with the instruments.
The experiments to be made by the
army and navy will be exhaustive. To
quote officials. the yacht race reports have
shown that the system is practicable for
general operation at sea. 1t only re-
mains to prove whether it will be salts
factory for naval and military purposes.
If a success il will be adopted by the
navy and the army in the Philippines will
be equipped with instruments. The light
house and life-saVing services would also
adopt it, and merchantmen will be adj
vised to equip their ships in order that
they may communicate with shore in case
of disaster.
Naval experiments will be made under
the general direction Of Rear Admiral
Farquhar, who will succeed Rear Admiral
Sampson in command of the North Allan
tic squadron. officers now witnessing the
operations of the system in connection
with the yacht races will conduct expert
ments at sea. Speaking of the matter to-
day Admiral Bradford said:
There is no question of its prospective
value L am not yet prepared, however,
to say how great that value will be. Off
GERS who are witnessing the present trials
have not submitted their reports.
Colonel James Allen acting chief signal
officer of the army, states that the two
automobiles recently bought will be used
in the army experiments. Small balloons
and kites will be employed and their use
may increase the distance over which a
message can be sent. He said:
The value of wireless telegraphy in
creases with distance. Thus, If a message
can be sent fifty miles and given a value,
for instance, of two, its dispatch over
one hundred miles would make the sys-
tenn worth four. Should the system op-
crate satisfactorily over one hundred
miles communication by wireless teleg-
raphy could be maintained between Key
West and Cuba, between the islands of
the Hawaiian group and between some
of the islands of the Philippine archi-
pelago. The best results with the system
have thus far been obtained over water
No satisfactory results have been secured
over a wooded country. Naturally we
are hopeful that the experiments will
show that the system can be operated
on land. 1t will then be highly valuable
in maintaining communication between
operating columns, between such columns.
and their base and between the besiesed
and their friends In case the system
proves successful instruments and the
necessary appliances will be sent to Ma

ing the experiments with wireless teleg-

bureau look forward to the possible use
of the invention in gathering information
