TELLS OF HIS TESTS

Marconi's latest achievement in sending
messages by wireless telegraph from Table
Head, Cape Breton, to Cornwall marks
triumph for which he has been laborings for
year past. Just one year ago he COM
municated between Newfoundland and Eng
land, sending the signal 50 December Is,
1901.
Marconi's modest little office at Table
Head has been flooded with congratulatory
messages from all parts Of the world, and
the inventor was In great spirits.
There was nothing at Table Head yester-
day to signalize his triumph. When seen
he at first stated that he had nothing more
to give out than had been contained in his
message Sunday.
What Marconi Says.
ct have no objections whatever" he said,
ito telling you between whom the messages
were sent In the first place, there was one
from Lord Mimic to King Edward, then
there was one from myself to the king, to
which 1 received very nice reply, con-
graduating me on my success. also sent
message to the King Of Italy and received
an answer Of congratulation In reply. Com
mander Martini of the Italian cruiser Carl
Alberta sent message to the Italian gov
eminent and received a reply. Other mes
sages were sent from DR.. Parkin to London
and by Sir Richard Cartwright. The mes
sage from Commander Martini to the Ital-
ian government was in Italian, and. despite
the difficulty of working with English oper-
ators, both were successfully transmitted.
I sent all these messages myself, and
they were received by Mr.. Woodward, chief
Of the receiving staff at Poldhu.
when did 1 first succeed in transmitting
messages from Table Head to Cornwall!
1T first
messages were, of course, all in code, and
were simply queries. such as How is thls?'
We would have been in position to trans
NIT messages much sooner but for delays
in obtaining machinery Of all kinds. We
are, as you can see. somewhat out of the
world here, and often we had to send as far
as Montreal for parts of machinery. A
slight defect was found in one of the in
struments and it required two days to rem
edy this.

1t was not before her object in being placed
at my disposal had been accomplished and

presence, and that was during the night

Marconi will remain at Table Head some
time and then proceed to the Cape Cod sta
ton. President Roosevelt will be asked to
communicate across the Atlantic through
the air.
Marconi's Progress.
The idea Of transmitting messages through
space by means of etheric waves, otherwise
wireless telegraphy, came to Marcon! while
a student at Bologna in the spring Of 1894,
while reading an account in Italian cleo
trical journal Of the work of Prof. Hertz,
who had died in January of that year.
He sent signals a short distance,
POpoff. Russian scientist, experiment.
ing with Hertz waves, was able to send
messages without wires for short dis
tances in 1895. Marconi was still at work
in Prof. Rights laboratory in the Univer-
sity of Bologna. Right was specialist in
Hertz wave phenomena. Messages were
sent a few yards.
Right improved on Popoff's methods and
Marconi improved on Rights. The dis
lance over which messages could be sent
was increased by Marconi'S use of a mast.
He adapted all known laboratory devices,
improved on the Branley coherer Invented
1890, devised an automatic decoherer, sent
a message 800 feet and discovered the dis
lance could be increased by increasing the
height Of his mast. He went to England in
July. 1896. Two to three miles was his
limit.
Telegraphed from ship in motion for
the first time experimental In the Italian
navy and on June 4, 1897, w. H. Preece,
the chief electrical expert Of the British
government, announced before the Royal
institution that Marconi by new plan
had sent signals through nine miles of
space.
Marconi continued experimenting In 1893.
Increased the distance covered by wire
less signals to eighteen miles for land and
water stations and communicated between
British men-of-w war at sea sixty miles apart.
March %. 1899, Marconi sent messages
between Dover, England. and Wimereux
Boulogne), France, distance Of thirty
miles Worldwide interest was aroused.
Marconi sent messages freely on land
and sea over eighty miles, one at time
or many simultaneously. October g, 1900.
abandoned high masts for receivers and
used cylinders only four feet high.
January %, 1901, day of Queen Victoria's
death, Marconi sent a message between st.
a distance of 200 miles. Later improved
apparatus and extended the possible dis
tances to be covered. December 1913, COM
muntcated between Newfoundland and
Cornwall. England. distance of 1,750 miles.
December 81, 1902. sent a message from
Nova Scotia to Cornwall, England.
