FURTHER TELEGRAPH MAKING IN ENG

LAND.
The London Times of the 2Sth ult, thus alludes
to the shore ends of the Atlantic Telegraph and to
further submarine cable manufacture now going
on:
On Sunday or Monday next, Mr.. Clifford starts
first for Naentia, and next for Newfoundland, with
the shore ends of the Atlantic cable. These ropes
are exceedingly massive, weighing upwards OF six
tons to the mile, and when these have been care
fully splced and added on, the Atlantic telegraph
will be complete, and trust remain for years
to come About five six miles of the shore end
at Naentia laid last year, and this length has
been buoyed so that Mr.. Clifford will only have to
grapple for it and to make the splice with the
rest Submerging the portion at Newfound-
land will require more and Il iudiciOuS
choice of position, but such cables in
such shallow waters can neither be lost or
broken. and in the of such an engineer
as Mr.. Clifford, they run little risk of either. In
short time also Mr. Canning, we believe, will have
to start with the great cable which is now being
made at Glass Elliott's and which is to be laid
down for the Electric and International Telegraph
Company between this country and the Hague
This is the largest and heavist cable that
has ever been yet manufactured, and it is not too
much to say that no other makers besides
Glass Elliott, in the world could produce wire
massive, and yet so finely and perfectly fin
ished. Up to the present time the electrical com
munications between this country and the Hague
have been maintained nomnally by four light
ropes, each containing one copper conductor
and each covered with solid iron wire. We say
nomlnay by four ropes though, really, it has rare
~ been by more than two, as, from the ShalOwneSs
of the water between Lowestoft and Holland some
one or more were always being injured by vessels
anchors, that it constantly necessary to keep
steamer employed to pick them up, mend them
and lay them down again. To put end osce
and for all to these perpetual of outlay the
company have determined the present mon
ster rope, combining the four wires in one and
otherwise of such strength and weight that if a
vessel Is so unfortunate to catch her anchor in it,
she will inialiby lose it, as, beyond a doubt she
can neither raise nor break this cable. 1t is com
posed OF an inner rope of four separately insulated
No. l3 copper wires, each caSed in its own gutta
percha, and the four twisted with hemp between
the lnterStices, into rope. This is bound round
by SIX large strands of creased hemp, and the
whole enclosed with ten iron wires, which have
no number in the trade, for EACH in fact, is
small iron rod being no less than x inch in
circumference The weight of the whole cable is
nearly 10 tons per mile, and its breaking strain
is upwards Of 100 tons. The length made is 40
miles; the distance between the points of landing
Dunwich, near Lowestott, and Zandvoort, about 80
miles from the Hague-is about 9S or 100 miles
Nearly 90 per cent, therefore, is allowed for slack
large margin, considering the immense strength
OF the cable, and that the vessel may put any strain
on it she pleases. The paying-ou machines to be
used on this occasion, are simply double drums of
great weight and strength, with friction clutches
of equal power to the size and weight of the drums
This machine used with the first Mediterranean
cable, and for the cable laid by Mr. Canning across
the Gulf Of St. Lawrence.
At Glass Elliott's works two other cables are
also in progress, one for the Submarine COMPANY
about 300 miles long, between Cromer, in Norfolk
and Emden, in Hanover, and another for the same
company to Denmark, near Cuxhaven, a distance of
$50 miles. Both these cables will be heavy as be-
comes the places they have to work across
