The Ocean Telegraph.

We find an article on the Ocean Telegraph in the
London Times of the 22d ult. We publish the fol-
lowing extract, for the sake Of the information il
containsupon project now of so much interest to
the people of this country. The Times is doubtful
o. the success of the enterprise, with the form o
cable which is proposed to be laid down, and its
reasons for the doubt would seem to possess some
what of weight: &C..
''Tbe iuterest with which the progress of this
great work is regarded on both sides of the Alta
tic will excuse our giving q brief description
of the various process s through which the cable
passas 10 IFS course towards completion. The con-
Quoting wire through which the electric current
will have 10 pass consists Of seven No. y copper
wires twisted into one strand, the thickness of
No 10 wire or about l-l6th Of an inch. This, we
believe, is made by the Gutta Percha Company, or
ct all events coated by them with three folds o.
gutta pescha which increases the diameter OF the
whole 10 three-eights Of iuch. In this form it is
delivered at the manufactures, coiled on wooden
drums in two mile lengths, with short piece OF the
copper conductor left out at each end Tor the pur-
pose OF Joining.
As these arrive at Greenwich the ends Of the
conductor are carefully brazed together, bound
round With eutta percha, and go joined 10 the en-
tire length Of the cable. which, ell 10 one place,

workman, therefore, who joins the ends, being j

proofs of the perfection with which the current

The strand machine in which the seven wires ar
placed revoves $50 times per minute, binding a.

strand. There ere 81 macbDes ct work. which
thus eyery "a hours converts 2 05S miles Of wire
into 294 miles OF strand, which is suffice to cover
about 10 miles of the cable. After the strand is
spun il is wound on TO bobbins, aud, having beer
carefully oiled and passed through a number Q.
guages to ensure its being of the requisite diameter
throughout, the bobbins placed in the closing
machine, which is, OF course, similar TO that used
for serving the yarn, but very much larger. BY
the revolution of is bObbns round the cable the
is strands Of wire are woven round il as TO form
