incident is one that suggests the need
Of close inspection of the wires. in
cities, to prevent such accidents
1t ought to be possible in this age
of invention to avoid the dangers
incident to crossed wires if the cross

avoided.
Marconi's latest achievement is
literally so far-reaching that ii. aug.
urs complete success in the COM
mercial use of the wireless system
in transcceanic communication:
Dispatches sent from the. station at
Poldhu, Cornwall, were received. on
the deck Of the steamship Philadel
phia when she was 1551h miles out,
and single letter signal was receiv-
ed when the ship had reached dis
ia nee of 2099 miles from Poldhu.
In speaking of this achievement the
Young inventor says that the results
have merely confirmed his observat-
ions during the recent experiment
in signaling from Poldhu to the coast
of Newfoundland, that the distance
from which wireless message canbe
sent is limited only by the power of
the sending machine. Marconi
declares that in three month he will
be competing with the cable COM
panies in sending commercial mess
ages across the sea, This prediction
ought to influence the action of Con
gress in regard to the Pacific cable
bill, now before it; and it will I'M
doubtedly have some influence on
transatlantic cable stock.
Narconi' $ reference to power as a
necessary element in the perfection
of space telegraphy touches upon a
matter az to which there is a great
deal of popular interest that of pro-
ducing the etheric waves which
quickly spread over a large radius.
Century Magazine for March contains
an instructive article on ''Marconi
and His Transatlantic Signal, 49, by
P.T.McGrath, an editor of St. John g
Newfoundland, who talked with the
inventor frequently during the weeks
in which he was conducting his in
itial transatlantic signaling expert
ments. In this article the inventor
defines the vibrations as a sort of
electrical earthquake. THE static
electricity of the ether is energized
by the oscillating current sent up
and down the aerial wire, and is
diff used through the intinity of space
As a comparison he explains that
an earthquake is manifesting Of the
material electricity Of nature and
these waves are her natural electric
ity. If a weight could be raised
sufficiently high, the shock of its
fall would be felt in England, and
the solution of The problem is the
providing Of a means of SO disturb
ing the ether as to product waves
the effect of which maybe apreci-
able all over the world
Marconi has thus far used in his
transatlantic experiments an ~ordin-
airy alternate current generator
having voltage Of about 1000. By
means of a system Of specially design
ed transformers and cundensers,
says the writer in the Century 1.-The
electrical pressure is increased to
$4,000 volts or thereabouts. This,
then, is the voltage available for
changing the perpendicular wires. y
The etheric waves produced by this
alternating current are sent out in
all directions like the waves which
emanate from center of disturbance
in water, and therefore a message
can be read in any direction from
the sending station, if the waves are
not interfered with by intervening
obstacle, by receiverss that are turn
ed to the key Of the transmitter. 1t
is the principle of the telephone with
the static electricity of the air as
the diaphragm which transmits the
vibrations.
