William Marconi reached this city yesterday
on the steamer Philadelphia after a trip that
was for him one of the most important since his
experiments with wireless telegraphy began, for
he succeeded in receiving aboard ship sentence
sent from the station at Poldhu, Cornwall. Eng
land when 1,551.5 miles from that station. This
beat all previous records for the transmission
of wireless messages by over thousand miles.
He also received signals, such as were received
last December in Newfoundland at a distance
of 2.O99 miles, or about the same distance as in
December. These signals to him as salts
factory test the sending of messages.
Mr.. MarcOni was accompanied on this trip by
H S. Saunders. one of the directors of the Mar
conf company: Wilfrid Blaydes, his private sec
retary; T. Vyvyan and J. D. Taylor. The latter
two will be in charge of the construction of
stations this side of the Atlantic. There
were also two skilled operators in the party.
Mr.. Marconi went to the Hoffman House, where
he spread out on the table in his room large
map of the Atlantic Ocean, marked with red
line by Captain A. r. Mills and Chief officer c.
Marsden of the Philadelphia, showing the course
OF the ship and the points at which messages
were received when these officers In the
receiving station of the ship. Every message
that came in their presence signed by them.
so that there should be no shadow of doubt as 10
its genuine character.
You see." said Mr.. Marconi. pointing with his
forefnger to cross on the curving red line that
fell south and little east of Newfoundland. in
latitude 42.1 north and longitude AZ % west,
there is the last point at which Communica-
tion was received from England. At that point.
2O99 miles away, only the much abused letter
s. received. But that is as good test as
any message. II SIS will come, any words will
come. The s. is easy to send; that's why
use It. And I shall keep on using it in my
periments 1t satisfies me- Now since Decem-
ber the Cornwall station, whence these signals
were sent has not been strengthened. AS this
point in the Atlantic is about the same distance
from Cornwall the station had in New
foundland. II seems to show that the power Of
the Cornwall station is just about enough at
present TO carry a message two thousand miles
1t viii be greatly strengthened soon. II seems
to me only question of power to send mas
sage around the globe
"Gnother satisfactory and important feature
Of the experiments made this trip" continued
Mr. MarcOni, was the fact that our receiving
instrument so tuned with the transmitting
instruments at Cornwall that not one Of the
messages sent received by any other boat
and could neither hear from nor speak to
any ship in midocean If the st. Louis had been
beside when receiving messages
from England. she could not have read one of
them. Not even the SIS were received by any
other boat, were they" he asked, turning to
one OF aIs assis 'ants. with laugh.
Il didn't hear Of any the assistant answered
also laughing
COULD NOT ANSWER THE MESSAGES
"Of course" Mr.. Marconi went on. I'VE could
not answer the messages after we were couple
of hundred miles out. for our instrument was
only OF low power Had we had a second instru-
ment tuned to the other instruments on the
liners. we could have both kept own secrets
and talked with other boats. But there was no
need of that. Experiments should be kept as
simple possible"
The inventor then explained how the station
