A. has already been mentioned in the
foreign news, the expectation is now en-
tertained Of renewing the attempt to lay the
Atlantic Telegraph cable, at the end Of
next June, or beginning Of July,-,he por.
tions already discharged from the steamships
Agamemnon and Niagara being left TO
hibernate" like q monster snake at the
yard in Plymouth, Eng.,-whle the man.
ufacters have again set 10 work TO supply
the deficiency Of some eight hundred miles o.
wire now existing. That portion Of the
cable lost, il is stated, is not useless, Z" for
the changes in the electrical condition Of the
wire is watched night and day, and will be
used for the purpose of throwing additional
light GU the subject OF terrestrial electro
magnetic currents" No fault whatever has
been found with the wire which broke last
year, with such unfortunate results. Many
important precautions and impro vements
suggested by that event will be introduced
in the new plan Of operations, but principally
in the paying out machines, with the special
design of guarding against the strain caused
by the sudden pitch of the vessel, and with
the break in the wheels so adjusted as to be
selfactiug, effectually preventing any undue
pressure. In relation to the plan more re.
Gently determined upon Of uniting the two
halves.of the Geographic wire in the middle
Of the ocean and from thence steering for
the opposite shore, the London Times says:
The opponents of this plan are to be found
among the deep sea fishermen, who generally
prefer the plan Of laying down the cable from
the New World to the Old, and who adj
vance among other reasons, the fact that
the set of Gulf stream is in this direction
and that il would be better for the expedi-
ton to have the current in its favor than
against IT, But, as We believe the influence
fthe Gulf stream does not extend below 20
fathoms depth, one is at IA loss to perceive
how il can effect an undertaking to submerge
q cable TO the depth Of more than 1000
fathoms. A more reasonable objection lies
in the fact that in the centre the cable must
be Joined, and that it mas been joined, and
that it is has been determined not to join
with five mile centre of steel wire, which
would give it tenfold strength at this point.
When to this deficiency we add the fact that
the lay Of each piece Of cable is made in
different direction, and that one portion
forms right and the other lcfthand screw,
each Of which helps the other TO untwist, we
cannot, however reluctantly, help seeing that
this joining in the centre is blot on the
whole scheme. OF course, a plan according
to which heavy square weight is to be at
tached to the joining has been devised to
prevent the wire untwisting il possible. But
a weight at this junction is = most serious
danger.
The Times remarks that there seems an
unusual demand just now for submarine
cables no less than five or six cables for
different places and Governments having
been lately completed ;-sne for the Swedish
Government; one for the Danish, 10 connect
Denmark with Sweden one to connect Cey-
lon and Colombo on the main land and one
to Join kurrachee with Calcutta.
In almost every instance, the conducting
wire is similar to that for the proposed At
lantic cable.
