Z" SPARK TELEG RAPHY,"

Concerning wireless teegraphy In the
German navy II is now asserted that
the experiments conducted have prov
ed a complete success, The emperor
Is reported to have expressed himself
as satisfied with the results obtained
by the so-called slaby -ArcO system
During the recent manoeuvres the adj
miral's flagship was mostly near the
spot where things were likely 10 CONF
TO an issue. and, therefore, frequently
changed It's position, steaming large
distances from one part to the other.
Spark telegraphy allowed the cou-
mander Of the fleet, with rare excep-
lions, TO always keep himself informed
Of all that was going on.
II seems TO have been established al
80 that thunderstorms, and warm, dry
air seriously interfere with the trans
mission Of messages The more humid
and cooler the air Is, the better II IS
adapted for that kind Of biography,
All the ships OF the German fleet are
at present fitted with instruments nee
essary for spark biography and the
apparatus Is In the charge Of carefully
trained men. No other Geographic sys-
TEN is,-that IS the opinion Of officers
better adapted for maintaining con-
slant communications between the adj
miral and his subordnates, notwith-
standing the drawbacks IN atmospher-
Ic conditions. These will, OF course, be
overcome In time,
Slgnor Marconl also reports having
obtained some successful results on
board the Italian ship Carlo Alberto
during the months Of July, August and
September last The transmitting sta
ton was poldhu. In Cornwall. Thence
messages were sent TO the Carlo Alber-
70 at Kronstadt. The speed OF trans
mission at a distance OF some loo
miles was. 1t is said, 10 words min
ute, Marconi it Is claimed, found u
way OF overcoming atmospheric dis
turbances, almost entirely.
Wonderful stories are told about the
way news was sent to the ship at sea.
on Farrell, the report says, the news Of
Europe was received daily from Poldhu
with perfect regularity, At Gibraltar
the ship was anchored In the innermost
part OF the bay, and yet In that
screened and secluded position tele-
grams came from Poldhu unfaillngly.
every word clear and precise, though OBJ
stacles Of land and sea had to be sur
mounted by the electric current. At
sea, between Gibraltar and Spezla, mes
sages were received and clearly writ
ten on the tape Of the Morse machine
Among the messages was one from the
management at Poldhu to the king of
Italy, which was transmitted without
fault across the continent Of Europe
Some OF the conclusions arrived ut
and stated in the report are as follows;
There Is no distance limit to the
propulsion OF electric waves over the
surface OF the globe, both sea and land,
provided that the energy Of the trans
mission is proportional 90 the distance
TO be covered. Land interposed between
the transmitting and the receiving sta

munlcations, The light OF the sun has
the effect OF diminishing the field Of ra-
diation Of electric waves, and therefore
renders necessary the employment Of
greater energy during the day than the
night. The Influence. also, OF atm0s-
pheric electric disturbances makes II

independent Of It, and at the same time
calls for an increase IN the energy %
transmission go as to obtain the same
results unon the less sensitive appara-
fuses. The efficiency OF the magnetic
iptecter has been shown by posivlte
experience 10 be superior 10 that Of any
kind Of coherer. and that not only by
It's not recurring any regulation. but
also by tho absolute accuracy Of rs
working and the great hardness and
sensltiveness Of the system"
II these conclusions are correct. II Is
evident tina, wireless telegraphy, or
spark telegraphy. Is an accomplished
fact. To be sure. its future possibii-
ties are clearly beyond even the most
sangune forecasts,
