New York, Nov. 1.-The Unite,
States steamship New York, flagship o
Rear Admiral Farquhar, and the bat
tleship Massachusetts returned to
night to the anchorage near Thirty
fifth street. North river, after beint
employed for three days in evolution
for the purpose of demonstrating tn,
working Of the Marconi system o
wireless telegraphy under various prac
tical conditions. The operations were
under the direction of board of three
naval officers, namely Lieutenant j
T. Newton, aboard the New York; j
w. Blish, with the instruments at Nav.
esink, N. j., and Lieutenant F. X Hill
on board the Massachusetts.
Mr. Marconi was handicapped by in.
complete instruments which he ha6
brought to the United States simply
for the purpose of reporting the inter-
national yacht races and was unable tc
give the government hoard as thorough
demonstration of the capabilities OF
the apparatus as he would have wish
ed. But the result of the working OF
the three sets Of instruments employed
in the tests Of the past three days was
to show the government board that
there is practical utility in the sys-
tenn which would be of great value to
naval vessels during evolutions Of any
kind and especially when on scouting
duty. The members of the government
will be obliged to call attention to the
fact that during these tests it was pos
sible for any instrument located within
the circumscribed radius Of transmits
sion to destroy the effectiveness of 9TH
er instruments at any time. While the
Massa chusette, for instance, was tele-
graphing to the New York the opera
same time and the result on the receiv-
ing side Of the New York's set was a
tumble of undecipherable characters
caused by the two sets of electrical inn
pulses reaching the instrument at the
same time. This was done deliberate
ly. Mr.. Marconi said that he could
prevent this interference on the part of
IL. I..% x,rxf
demonstrate it during these tests
because he had not yet received his
patent for that feature.
practical use of the wireless tele-
graph that pleased all the naval board
took place to-day. While the New
York and Massachusetts, were putting
out to sea- the Massachusetts in the
rear, a message was clicked from one
vessel to the other than a man was
overheard. The battleshp's lifeboats
We're rapidly lowered and were soon
pulling for the rescue of the unlucky
Jackie. Signals were sent aloft notify
ing the flagship what had occurred, but
during the ten minutes occupied in dis
playing the message Admiral Farquhar
had been in constant communication
with the Massachusetts by wireless tel
egraph and had learned that the man
overheard had caught the life buoy
thrown by a sailor and was therefore
not in much danger. Admiral Farquhar
ordered the Massa achusetts to report
when the man had been picked up, and
half an hour later, while those on deck
were watching the return of the port
Iifeboat through their glasses and Won
ierng which boat had succeeded in res
cuing him, the receiver in the instru-
ment room recorded that the starboard
which had been hidden from
view from the New York, had made the
rescue and been hoisted aboard.
Beyond the simple test of the ability
Of the instruments to transmit and re-
ceive messages the government boards
called for long distance
and interference tests.
On Monday the New York hovered
about the Sandy Hook lghtship and the
steamed off east at about
twelve knots. Constant communication
was kept up between the two ships, the
Instruments working without hitch
until the battleship had proceeded thir-
w miles. linen the recording OF llle
impulses from the Massachusetts by the
receiver aboard the New York began
20 grow weaker and at thirty-siX miles
became unreadable. Mr.. Marconi eX-
pressed regret at his inability to show
he board transmission at eighty miles,
which would have been possible with
more preparation.
Five successful interferences were
made OH that day by the Massachusetts,
while the Navesink station was send
ng to the New York. The wind kicked
Up such sea on Tuesday that both
ships came inside and anchored eight
niles apart The two ships, however,
we're in communication throughout the
lay and messages We're exchanged ev-
,ry few minutes. There will be work
when the instruments on
he New York will be taken to sea on
torpedo boat. This will test the abil-
ty of the apparatus to stand the more
,iolent rolling and lurching of a smaller
yessel.
