Tests Outside the Hook by the Mnssn chusetts
and New York An Interference station
on Shore Interrupts Communication,
but Inventor Says He Can Prevent This.
The test OF Marconi's wireless telegraphy
was concluded yesterday afternoon as far rs
the experiment applies to United States war
ships. The tests were made on the cruiser
New York and tho battleship Massachu-
sets by special commission appointed by the
Navy Department. Tho commission consisted
OF Lieutenant. Commander J. 4. Newton. Lieut.
John d. Blish and Lieut.. F. q. Hill. Mr..
Marconi conducted the experiments on board
the New York under the direction OF
Lieutenant Commantler Newton. Lieut.. Hill
was on the Massachusetts,. and Lieut.
Blish was at tho Highlands OF NnvesInk.
where wireless telegraphy apparatus had
been set UP for the purpose Of intsrrupting
messages sent between the New York and
Massachusetts. The Interference apparatus
on the Highlands consisted ot l50-foot ver-
tical wire triced up on pole. To the foot OF
this wire Marconi teleRraphing instrument
was attached so that when message was sent
from the Navsslnk station It would interrupt
any messages being sent at the same time
within the radial circumference OF tho electro
cal waves produced ny the sending OF the mes
sage.
The two warships left their anchorage OF
West Thirty-lfth street on Monday forenoon
and went down the bay. where tho tests were
begun. On the way messages were exchanged
successfully and to the expressed satisfaction OF
the commission. When the warships arrived of
Navesink the New York anchored and tho
Massachusetts, steamed out to sea thirty-sx
miles for the purpose Of making long distance
tests and also to try the extent Of the interior
ence the apparatus at Navesink would exer-
else while messages were being exchanged
between the warshps.
All the time the Massachusetts was making
her way to sea messages were exchanged be-
tween her and the New York at Intervals OF
ton minutes. and interference messages were
sent by the operator at Nave.lnk at longer in
tervals. The interference messages were sue
cessful and rendered the messages between
the warships unintelgabls, The eject was
the same as Il two messages had been set up in
type and then the type m ixed ind i.criminately.
A. distance 81 thirty-'x miles the messages
and anchored few hundred yards from the
New York; During The Jay i?rty-hys, mes.
twenty-three were received and five were in

Massachusetts, were compelled by the rough
weather TO como inside Sandy Hook. While
