claimed to be free from such dis
turbances. The introduction of Il
very large copper wire and the alter
alton of the instruments, so as to
embody certain deSiderata, have
been made; and it is stated that no
less than forty words per minute
have been transmitted without any
necessity having arisen for obtaining
a single repetition. If this report
be true (and there appears to be
ample confirmation that it is SO), the
most sanguine expectations of per-
sons interested in this latest Scien-
tifc wonder have been fully realized.
The following brief description
appeared in a local newspaper on
March goth:
Copper wires of a very large
gauge have been erected parallel
with each other, one on the sea
front at LavernOck Point and one
across the Flat Holm, near the light
houSe-three miles apart-and the
Morse code signals transmitted are
very distinct. Many Improvements
in the apparatus have been intro
duced since the previous trials were
carried out, and it is very satisfac-
tory to know that high speed of
working has been attained. The
vibrations transmitted through space
from the electric motor produce on
the telephone receiver a most pleas
ing tone, and the combination of
dots and daSheS are easily readable
by manipulation. AS many as
forty words a minute have been sig
nailed across and read without any
difficulty whatever. There can be
no doubt that the system of COM
munication now permanently eStab-
lished between the fort on the main
land to the fort on the Flat Holm
will mark an important epoch in the
telegraphic developments Of the CEN
tury, and Mr.. w. H. Preece is to be
congratulated on the great success
his method has attained. The two
of So-called wireless teleg-
raphy, which have recently created
such widespread interest, were fully
explained to Cardiff audience at
Mr.. Gavey'S recent lecture before
the Cardiff NaturaliStS' Society.
The postoffce has conSideredit wise,
for various reasons, to establish the
permanent communication between
Lavernock and the Flat Holm by
means of the electromagnetic rather
than by Marconi'S system, and,
without entering into technical de-
tails or criticising the action of the
Department in this matter, we can
merely say that a thoroughly salts
factory and trustworthy telegraph
service is now established between
these two points which, there is
every reason to believe, will be free
from the disturbing influences to
which other methods are subject.
From other sources, gather that
on the mainland a stout copper wire
has been fixed, as ordinarily, to
poles, the length of the wire being
three-fourthS of a mile. The ends
of this wire run into the sea. On
the island a similar wire runs eX-
actly parallel, as previously men
toned, to that on the mainland; and
the length of the island wire is
about half mile, with the ends run
to earth. 1t seems that the length
of the parallel wires is governed by
the extent of the space between
them. The transmitting and re-
ceiving apparatus are duplicated,
and it is said that the system is less
costly than that of Marconi; that
the parts of the apparatus are not
so delicate; and that the necessity
of having the instruments Practi-
