I For Sending News to Daily Pnperas
Signor Marconi Finished his expert
mental work at the wireless telegraph
station In Wellfeet. Mass, early tliss
other forenoon and left for New York
on the afternoon train. says the New

4 For the first time that day Marcolli
consented to take the newspaper corres
spondents into the operating room aud
explain the process by which the Herts
.zian waves are started on their way
through the ether. The room is aboitf
thirty, feet square. Near the dooi. is d
raised platform upon which the opera
tor stands while sending. The key is
on shelf, and on the wall there is IL
switch which turns on or shuts of tile
power from the dynamo.
H First sendings by the wireless meth
od were done by means of a wooden
lever which operated pump handle
fashion The new key devised by Mar
conf. while several times; larger tiissn
the regulation telegraph key, is like it
in many respects. 1t is about twelve

gutta percha button and has platinum
contact points. The play between the:
contacts was about an inch. This, Of
course, can be regulated. but a consids
cradle play is necessary to prevent
sticking. st
room floor space is occupied by con-
densers. They are about waist high
ard form q squarein the room. Cross
ing, them from corner to corner are tive
pieces Of sheet zinc about a foot wide
and ten or twelve feet long, At the left;
end Of the room from the entrance are
the electrodes, with three square foii
tanks for cooling purposes and two sii-
very globes about the size Of a croquet
ball. Il s3 N IS 81; 4;
There is space of about four inches
between these globes. and 1t is the
crossing Of the electricity over this adr3
bridge from. one electrode to the other
that gives the spark and the loud re-s
ports when the operator is busy with
the key. One OF the electrodes, he said
was connected with the aerial wires
and the other witch the ground. Wbea.
tho electricity was switched into the
condensers, it gathered force. passed
to the outer wires and down to an
electrode. n! ~ 81
The opening and closing Of the key
caused the wires to charge and dis
charge and the jumping Of the current
across the air space from one electrode
to the other gave the pulsations which
the ether took up and carried to- the
other side of the Atlantic. i,
Assistant Kemp turned the current
on at word from Marconi, and the
quick opening and closing of the key
was responded to by a spark between
the electrodes almost binding In vivid
ness. The reports were like the crac-
kle heard when lightning strikes at no
great distance. The letter .sP' or the
numeral "6' in American Morse sug-
gested machine gun fire. Dashes were
q kind Of Zip" q running together of
dots M II s s3s
Before taking hold OF the key Mar
conf stuffed his ears with cotton to
deaden the sound and told the visitors
that eventually operators would have
q sound proof booth to work In.
The receiving Instruments are in the
same room. The ether waves when
they arrive from Glace Bay Cor Poldhu
are rather feeble, but Marconi's mag
netic detector rejuvenates the tired vi
brations and gives them through a
telephone receiver or on q recording
tape ia clean cut dots and dashes.
4 Speaking OF his latest and greatest
project, which is nothing less than the
establishment at some central point In
the United States OF q wireless station
from which the news now sent over
wires may be sent direct and simulta-
neously to every newspaper equipped
with Marconi receiving apparatus, Mr.. 4
Marconi recently said to Il New York
Evening Journal reporter: 4,
'.I consider this the greatest appara-
tus have vet contempla tied. If it is I
carried out as at present planned there
will be q central sta ton 4 at. say, st.
