tn r proposed experiment of sending mes
sages from the top of the Eiffel tower in
Paris to the dome of ST Paul's cathedral
II London. MarconFs experiments de-
mand a vertical wire. while Tesla claims
20 send his messages by an affinity OF
sound through any substance capable Of
transmitting sound OF vibration. In
comparison OF statements Tssla's inyen-
ton is the more valuable.
In special correspondence from London
the World prints the following statement.
In which the necessity OF air as a trans
mitter is set forth:
Most OF Europes really great scientists
give the boy as much credit for the dis
eoyery OF the value OF the vertical wire

coherers as they would give him II he
had created the whole electrical scheme
utilized II new instruments.
When | suggested 10 MIN TO make the
experiment of sending a message from
St Pauis cathedral 10 the Eiffel tower.
he modestly shook his head and said:
But how do ! know? ! have only tel
egraphed twelve miles. What If my IN
struments and my system prove unequal
10 the great task? / am unwilling TO pre-
diet anything.
But arrangements for the experiment
are at last we'll under way and Will be
made within a few weeks. IL involves
the construction OF new and more power
ful instruments than are at present in
existence. Marconi will attempt to send
the message from st. PaulS in London to
the Eiffel tower in Paris.
THE Importance attached TO young
Marconfs invention is shown By the fact
that the Italian government has been ex-
perimenting at a cost of 5000 day for
weeks. has decided that II is the greatest
discovery Of the time. and has secured
patent rights for Italy, all other rights
being owned by Marconi and associates
In his company, which has already paid
him over $i101
when public experiments were con-
Quoted In Italy the enthusiasm Of the Of
ficials and popUlace over the seemingly
supernatural results reached a point OF
almost frenzy. and the young inventor
received such an ovation as falls to the
lot OF bat few men.
Wires No Longer Needed.
Experiments made by the German
government are laughed at by German
scientists. but in Berlin itself Prof Slaby
carried out the most successful expert
ments by passing a current. without
wires. through brick walls and other OBJ
structions, believed 10 be insurmountabe
by his skeptical colleagues. He had been
present at experiments carried on by
Preece. the chief engineer OF the govern
ment telegraphs IN Great Britain In Lon
don, and had made his own instruments,
and Is now carrying on public expert
ments daily TO show that no known body
has any effect on the passage of the cur

ends Of the route
"Marconl says OF his work. My expert
ments have proved shat the distance over
which meSSe ges can be transmitted in
creases in geometrical or nearly geometri-
cal. ratio 10 the height OF the vertical wire.
Thus. while a wire thirty feet i'm
height IS required 20 telegraph one and
oue-half miles a wire double that height
will get range OF over five miles

height and II Will be possible | think 70

kites. According TO this ratio and acting
on the theory that ON the height Of the
vertical wire depends the distance 10 which
a message can be transmitted. / believe
