LONDON, April 1.-(New York World
Cablegram-Special Telegram Jon be-
half of the American people, the
World congratulates you on your
marvellous achievements in transmit
ting telegraphic messages without
wires between the shores of England and
France, and express their hope that at no
distant day these islands and the continent
of America may be Joined by the same magic
bond"
This message was dictated last night by
the World correspondent to operators of
Marconi's instruments in a little room at
tached to South Foreland light, whence the
first communication by the wireless teleg-
raphy was opened between England and
France 1t was dispatched almost as
speedily as by ordinary telegraphy and
shortly the reply came on the tape in
steady flow from the corresponding station
at WimereuX, thirty-two miles across the
restless sea:
1--WE thank the World for its message on
behalf of the people who Nave ever been
foremost in inventive genius, and cordially
second the aspiration that this system may
span the Atlantic as it now does the English
channel"
The apparatus by which this momentous
scientific development was attained stood on
a little table in the center of a plain room.
Fifty primary cells in which the current
was generated were under table. When
the president made the contact by pressing
key an electric spark three -fourths of an
inch long flashed out from knob on one
pole to the other and escaped into space off
a pole outside the building and was received
instantaneously by the instrument at
rhn ,ND1o nork x,ta, opn
$50 feet high. The message was sent at the
rate OF seventeen words per minute. while
the reply came at a rate of fifteen, the cur
rent employed being the same as used in the
messages to East Goodwin lightshp, only
six miles away. Messages both going and
| coming were recorded by a bell whose
eounds could he read by anyone acquainted
with the Morse code.
Marconi in an interview stated: "The
cost of the method of transmission is in
finitesimical compared with cabling. The
whole installation by which these demon
stratons were carried out cost only about
S1,250. With multiplication the expenditure
is greatly reduced"
| What will be your next eXperiments?"
II hope between New Haven and Dieppe,
a distance OF sixtyfour miles 1 only re-
! quire authorization from the French gov
ernment to set up my stations French gov
ernment experts have been deeply interested
! in these experiments and are preparing an
exhaustive report on the possibilities OF my
system. The French government has given
me more encouragement far than any
! other"
May Span the Atlantic.
"Is wireless communication across the At
| lantic practicable?
| Speaking broadly l believe so, but / have
not yet made calculations with that in view.
! l expect it would require a tower on the
coast Of the west of Ireland and the United
States 1000 to 1900 feet high, with certain
| lengths Of wire netting to catch the current
and make the circuit. l don't positively
affirm that this demonstration Is possible,
as there are many difficulties, but when
seriously tackled no doubt they could be
overcome The outlay would be heavy, as
the erection of the towers required would
! be costly, but much less than cable at the
outside estimate. AS | go on improving my
appliances | reduce the cost and by the time
! transatlantic transmission is seriously in
hand the outlay doubtless would be greatly
reduced. But all that is a matter for the
| future. l am going to America in the
! autumn, when perhaps the question will as
sumo a practical shape"
/ Lord Kelvin, interviewed, said: II am no,
! at all surprised at the results attained by
Marconi l believe wireless telegraphy hae
already become practical success and its
future is immense. For over-sea communi-
cation 1t has many advantages which will
| make II invaluable"
Prof Sylvanus Thompson, Englands most
distinguished electrician, says: "Marconi'e
demonstration Is the natural development OF
the principles propounded by Hertz and
! Oliver Lodge. 1t will be possible to estab-
Iish direct communication across space
either between England. the Cape and India
or even Australia. 1t Is far cheaper than
by the submarine cable. Nine years ago
offered to establish telegraphic communica
ton with the Cape provided $4,000 was
forthcoming, but the scheme was treated as
visionary. Before long / believe you will
| see it realized"
Marconi's achievement has excited intense
interest in all classes here and when Parlla.
ment reassembles the ministry will be ques-
toned why 1t has not given more generous
assistance to the inventor in demonstrating
the value Of his system
Tesla's criticisms of MarcOni's demonstra
tions are causing controversy among elec
trcians. Prof Fleming, who was present a
tho demonstrations today at South Forelan
said Tesla says that the introduction O
| an inductiye coil anywhere between tn,
terminals would destroy communication
which would prove vital defect. Well. a,
an answer TO that allegation, | may point ou
that in the next room to this there is /
large induction coil in connection with a
4,0O0-candle power light OF this lighthouse
and that the coil has not had the slightes
effect on Marconi's instrument"
