MEDITERRANEAN ELECTRIC TELEGRAPH

COMPANY.

The Mediterranean Electric Telegraph Company
is on the point of despatching their cable, which is shortly
to complete the telegraphic communication between Lon-
don and Algiers. It will be remembered that last year 110
miles of cable were sent out from England, and hid down
between Speszia and the most northern point of Conies.
For this section of the line 90 miles of cable, weighing eight
tons to the mile, and containing six insulated wires, were
required ; the remainder was taken to the straits between
Corsica and Sardinia, and twelve miles were laid down
there, the communication basing in the mean time been
completed along the island of Corsica by land. The re-
mainder, which had been sent out to ensure a sufficient
quantity, was then brought home (in length about eight
miles), and spliced to the cable just about to be
sent out. The communication being now complete from
_ _

London to Cagliari, in the south of Sareilis, and

ter, belonging to Me. Green, of Blackwell, and commandid
by Mr. Kell, the same gentleman who conducted the pre-
vious operation so successfully. This cable is the largest
and heaviest, besides being the longest, ever laid down, It
V 160 miles loag, each mile weighing 8 toes, and the whole
cable weighing 1,900 tons. This is exclasive of 12 mike of
lighter cable sent with it to avoid all chance of deficiency.
This cable is the manufacture of Messrs. W.Keeper and Co.,
of Lesdenhell-street. Its stowage demands the greatest
*are, owing to the enormous weight, sad to the circumstance
that it is all in one piece. Seventy-one miles of it have
been pat in the lower hold, forty-two miles on the orlop
deck, thirty miles in %wee° decks, seven miles in the after
held, and the twelve spare miles of what is called small
table, although it weighs five tons to the mile, is also on
tween decks, and every one of these portions has to be
shored at very short intervals, to prevent the movement
of the cable. Altogether, the weight which will be
seat in this vessel will be 1,960 tons— a weight
which Csp'ain Kell informed us with pride only made
her draw 22 feet 6 inches of water. In laying down
the last portion of the cable, that between Spenia and
Corsica, it took five days, including the stoppage that had
to take place in cutting the cable, and going round to lay
the short lengths between Corsica end Sardinia. It is ex-
penned that the present cable will be laid down in tour
days. The Mediterranean Telegraph Company anticipate
that in two years and a half they will have a direct com-
munication with Bombay, and from thence, by telegraphs
already at work in the presidencies, to Calcutta ; and they
corsider this line they are just about to complete as only the
preliminary steps to this result. Their proposed line, join-
ing the one at present open to Cagliari at Caps Spud-
vents, will first be taken to Malta, and thence direct under
the Mediterranean to Alexandria. This will be an is.

Professor Faraday, about two years age: •.:alled the atten-
tion of telegraph companies to the tact ae,at there was great
difficulty in sending any communicatx

length of wire than 300 miles; but

Brett ha been experimenting, with a view to overcome this
