WIRELESS T~ELEGRAPHY
1T MAY BE ADOPTED FOR USE on
UNITED STATES WARSHIPs.
Devices of the Agricultural Depart
ment's Experts to BE Tried-In-
vcntiOn by a Belgian.

WASHINGTON, March 7.-Since last
autumn the Navy Department has sus-
pended the experiments in the employment
of wireless telegraphy as a means of COM
munication between naval vessels and be-
tween vessels and the shore. Up to this
time none of the warships has been
equipped with a permanent plant. While it
may be true that Marconi is coming to
the United States, and that he may, while
here. communicate to the Navy Depart
ment some proposition looking to the in
stallation of his own system of telegraphy
ment has not yet engaged him to do so.
Rear Admiral Bradford, chief OF the equip
ment bureau. which naturally would in
stall any such means OF communication,
has had conferences with SOM of the
most eminent electricians in the United
States as to the availability of the wire
less telegraph for naval use. But so far
nothing like the ideal system has been
found. The latest proposition has been
preached by the Department of Agricul-
ture. Secretary Wilson. hearing that the
navy was casting about for a serviceable
system OF biography, has written Admiral
Bradford to notify him that the Agricul-

and has attained remarkable results. His
experts assert, with the greatest positive
ness, that they have evolved a system radi-
cally different from Marconi's and of far
greater efficiency. For obvious reasons the
details Of the process are kept secret. but
1t is probable that within a short time a
practical exhibition will be made on board
of a naval vessel. The bureau of equipment
fortunately has a considerable appropria-
ton made in a lump sum at it's disposal
TO cover the expenses of installing all
kinds of electrical Appliances, aside from
those connected with the mechanical de-
partment of the ship, and when Secretary
Long gives the order a part of this will
be spent in trying Secretary Wilson's ex-
pertS' devices. The outcome will be watched
witt the greatest interest by all naval
men. particularly in view of the announce
ment that not only Great Britain, but Ger
many and the other European maritime
powers already have ordered the instaila-
tion OF wireless plants In their navies.
An interesting account Of successful ex-
periments In wireless telegraphy Is con-
tanned in reports received at the State De-
partment from Consul George w. Roosevelt
at Brussels, Belgium. The experiments
were conducted by Emile Guarini, the in
ventor of an automatic repeater. He first
attempted to transmit wireless messages
direct from Brussels TO Antwerp a dis
lance OF twenty-five miles, and thoroughly
established the futility of tempting to
send messages over such a distance without
the aid of captive balloons or masts. He
then turned all his attention toward the
transmission OF the electric rays by relays.
and in this. IL Is stated. was entirely sue
cessful. He telegraphed from a station on
top OF q structure In Brussels 10 one on
the tower Of st. Rombant Church I'm Ma
linese. Numerous. messages. says Consul
Roosevelt. were received and transmitted
with great distinctness, and two messages
were received at "A time when communica-
ton with the ground from the t-ransmitter
had been interrupted. This was the first
instance on record where wireless messages
were exchanged between two large cities
with the antennes placed on high monu-
ments and without the help Of captive bal
looms or kites. The rays arriving at Ma
linese traversed several

a large part OF Malinese itself. over Chin

which tend to stop or weaken the electrical
vibrations. Mr.. Guarinis system involves
the method used In ordinary t~elegraphing
OF relays and transmitter, the transmitters
at stations repeating the message auto
maticaily as received. Mr.. Guarini presents
a formidable argument against the hope
hat great distances will ever be traversed
AT a single fash. ''The world is round.'
he says, 'and the rays spread In a straight
