Inventor of the System Comes to Re-
port Cup Races without Wires.
| New York, Sept. 22-Signor Marconi
the inventor of wireless telegraphy
whose arrival yesterday was noted in
these dispatches, will attempt to dem
onstrate the practicability of his mar
Vicious system of communication with
out the aid of visible connecting agents
by employing 1t in reporting for New
| York paper the races for the America s
cup. He has with him complete para
phernalia for his experiments.
To New York Herald reporter Sig
nor Marconi chatted very freely about
what had been done in the develop
ment of wireless biography and what
he hoped to accomplish in the future.
He was very enthusiastic over the idea
of reporting the yacht races, and his
confidence in the success of the work
was firm.
I'VE will be able to send the details
of the racing to New York and thence
to Chicago as accurately and as quick
ly almost as you could telephone
them.' he said. THE distance involved
I is nothing, nor will hills or buildings
interfere with the communication. In
we sent messages over much greater
distances than we have to contend with
in this case. l have conducted many
tests from moving vessels to stationary
and moving receiving points with COM
plete satisfaction.
The most remarkable perhaps was
made during the recent British naval
maneuvers. The admiralty is very

asked me to install my system on board
three ships of the fleet that was en-
gagged in defending the coasts of Eng
land. The scouting cruiser Juno and
the flagship Alexandra were two of
three equipped. I was on board the
flagship and during the cruise did not
get much sleep. The scouts We're di-
rected to report every vessel sighted,
she was steering and everything about
her. They also reported routine mat
tiers to the admiral.
Between midnight and o'clock in
the morning we frequently transmitted
as many as 200 messages Except for
these reports the admiral had no def
mite idea where his scouts We're. nor
would the scouts have known of the
fleet. The distance between the two of
course varied. but the system worked
Well whether it was short or long. From
the scout not trace of the smoke from
the tunnels of the thirty warships of
the fleet could be seen, yet the lnstru-
ment down in the stateroom was click
ing out orders from the admiral every
few minutes.
Finally the Juno sighted the vessels
she was looking for, and the message
this Information was sent by
the operator on board. Eighty miles
distant Sir Compton Domville. in the
Alexandra, received the news which
enabled him to outmaneuver the enc
my's fleet, bring in the convoy in safety
and win the mimic naval contest
Another thing we have found is that
mountains, high mountains, steel
lmasts, etc, do not stop communication
We We're able, While in Bantry bay, to
talk with ship lying many miles from
US and separated by a chain of hills
hundreds of feet high. The message
radiated in all directions and was
caught by the pole on the other ship.
Again, very valuable point is that
fog does not interfere with wireless
gtelegraphic message at all. In fact, at
times the instruments have appeared to
work better in thick weather The
curvature of the earth has also been
discounted. With a pole sufficiently
high message can practically be sent
any distance. There was some talk of
my attempting TO communicate between
New York and Chicago, but / do not
think shall make the experiment.
may, however, try it,
4 1t is interesting to note that Signor
Marconi did not begin his experiments
until 1885,, when he began TO erect poles

/ ton between various parts of his fa-
hther's estate near Bologna. in Italy In
1886 he arrived in England, and after
working in conjunction with w. H.
Preece, then chief electrician of the
British postofice, he gave demonstra-
ton of the capabilities of the system
during the volunteer evoutions on
Salisbury Plain, and also in the British
channel More ambitious experiments
followed and wireless telegraphy be-
came fact and not a theory only.
