TRIALS WERE A
BRILLIANT SUCCESS
Marconi Wireless Telegraphy Tested
Under the Most Thorough Con-
ditions by the Navy,

New York, Oct. 30.-Over 90 miles Of
the Atlantic ocean, over house tons
church spires, towering office buildings
the Marconi electrical ripples success
fully carried and dropped messages
between two moving warships to-day.
The naval test at sea proved that with
in a radius of 81 miles messages can
be transmitted by wireless telegra ply
with all the accuracy and precision of
an ordinary land line This proved
that hills, high buildings and wires do
not break the force of the electrical
waves and do not interfere in the
slightest degree with the transmission
of messages. BY Encouragement.
operations on board the New York
were conducted by Marconi himself.
One Of his assistants named Bradfield
operated the instrument on the Massa
chusetts. while Telegrapher Bowden.
another Marconi expert, was stationed
in the lighthouse on the highlands of
Navesink. From the Marconi trans
mftter on the lower floor of the light
house annex, the wire was carried
through the window up the tall flag
staff and up a sort of topmast, max
ing it's total height above the ground
about $50 feet. Through the hatch
ways of the two warships the wires
were extended to the same height.
The message which the New York,
as she passed down the North river,
sent to the Massachusetts lying at her
| anchorage at 35th street was read
| plainly in dots and dashes at Navesink,
| 10 miles away. 1t was:
| Follow us down at p M
This message was the overture TO the
| telegraph testing programme, when
included about rs messages, all OF
which had been prepared by the naval
board and We're especially difficult. EV-
cry five minutes during it's course down
the river the New York telegraphed
over the constantly increasing distance
| to the Massachusetts,, and the battle
ship replied to the flagship without a
break All the messages in the corre-
| spondence were caught at Navesink
| and a careful record of them was kept
1t was during the voyage down the
| river that an official test for interior
ence" was made. Without any warn
ing to Marconi, the operator at Nave
| sink, at the direction Of Lieutenant
| Bliss, sent several messag es in quick
succession to the flagship, the result
| being message from the Massacnu-
setts to the New York:
| "Navesink has successfully inter-
fered"
| But a few minutes later the light
house caught Marconis explanation
| that one of the ground wires on the
New York had not been secured prop
erly, which allowed the stray messages
| to break in on the conversation be-
| tween the two warships.
| 1t was a long time after the tele-
graphing began before either OF the
warships were visible from the light
house. Without wire, without any
| apparent connection. messages kept
dropping out of space. as If some su-
| pernatural power were hufllnS tneln
| down from the clouds.
| The New York came in sight about IL
! o'clock, and although messages from
| the Massa chusetts continued to ram
| down as fast as the receiving lnstru-
ment could reel off, it was fully two
| hours before she could be made out
| creeping slowly toward the flagship.
| Then the New York wired the Massa-
chusetts:
| Put out to sea in a straight line,
keeping careful account of your dis
| lance
| The black smoke of, the Massachu-
sets a few minutes later trailing pack
towards the Highlands showed that she
was obeying. The telegraphlng con
! tinued for more than an hour with Just
as much accuracy as that with which
two operators convey between Yonkers
and New York.
When about IA miles of gray ocean
| were between the two ships sy.lables
began to drop out of words: sentences
were received in which articles ana
propositions were missing. Later
longer words began to disappear un-
til finally the Massachusetts, messages
| became uninteligible at the light
house, although she was evidently in
| communication with the New YORK
| still The last intelligible message
| from the Massachusetts was sent at
1912 D. M, when she was q miles
from shore and IS miles from the New
York.
