Experiments.

London. Sept. L-Marconi's system OF
wireless biography is now in practical
commercial operation. The great Inventor

voyage on the Carlo Alberto. have once
more drawn public attention 10 his remark

data as TO the utIitarian aspect Of this
new form of communication. one OF our
representatives called upon Mr.. II. Cuth-
bert Hall. managing director OF the Mar
conf Wireless Telegraph Company. Limited.
and was favored with a detailed statement
on the subject.
Nfr. Hall at the outset described the long
distance station at Poidhu. in Cornwall.
which has been installed 10 communicate
with the station at Cape Breton, in Can
ada. and with a second station at Cape
Cod. Mass Mr.. Hall continues: In COM
municating over long distances a certain
amount OF experiment IS necessary. II is
found in practice that before a continuous
nov OF messages can be secured the plant
has 10 be adjusted 10 a nicely; and the
additions or notifications which may be
required are ascertained by preliminary
tests. We have had sucl a test quite re-
cently between Poldhu and kronstandt.
This took place from the ship of the ltal-
ian Navy, the Carlo Alberto. during the
visit of the King Of Italy TO the Gar, MI

telegraph communication over long stretches

about four times as obstructive as water.
A very large part OF the ransmiSsion be-

Mr.. Hall was asked for his view concern
ing the establishment Of an electric postal
system. but beyond the suggestion that the
method to be adopted might be that known
as telpherage, n that In all likelihood the
system would be from one point TO another,

he would not hazard an opinion. He de-
