The above table gives put few of the places
with which our merchants and others cores
pond, and the numbe Of days set down would,
in many instances indicate quick despatch. 1t
will, then, be seen that the time to be saved by
the cables will be from four TO thirty days
Another great advantage to arise from the con-
struction of these lines will be that of daily
communication; whereas, under the present
system, days, weeks, and often months must
elapse before intelligence can be obtained from
distant points.
DESCRIPTION OF THE CABLE.
The cable already laid was manufactured at
Silverton, England, by the India Rubber, Gutta
Percha, and Telegraph Works Company, the
ilectors OF which agreed to receive no pay for
their work until 1t had been found to give entire
satisfaction after submersion. The Cuba cable
is constructed in three parts. All of these are
composed OF the same materials, ViZ.:-An outer
sheathing of galvanized iron wire, of thickness
differing to the depth of water, and three coats
of gutta percha surrounding the conducting
wires which are seven in number. The copper
wire is about one hundred and seven pounds
to the mile, while the gutta percha covering
weighs one hundred and seventy pounds
per mile. The shore end of the cable, extending
from Key West, in Florida, to Sandy Light, is
protected by very thick iron wire, and weighs
three hundred fathoms water it is to be dimi-
nished in size and weigh nine tons per mile.
The deep sea portion is again smaller, Weighing
two and one-half tons per mile. 1t is three
quarters of an inch in diameter or rather less
than the Atlantic cable; but not nearly so much
strain will be brought upon 1t as the latter had
to stand, as the greatest depth of water is only
eight hundred fathOms, whereas the Atlantic
cable had to be laid in some places at a depth
OF two thousand fathoms No difficulty is ap-
pretended, therefore, in submerging the cable,
while the comparative shallow depth of water
would render graphing for lost eEd in case of
accident quite easy.
LAYING THE CABLE.
On July 26 the English steamer Narva, with
the cable on board arrived off Moro Castle,
when she was met by the authorities and noti-
ned not to enter the port of Havana. She ac.
cordingly started for Key West and on the Sd
of August the shore end was landed at that
point. On the daY following twenty miles of the
cable was paid out, when 1t was cut and buoyed.
The Narva then returned to Havana, where she
arrived on the 8th, and during the same day
landed the cable ut the hamlet OF Chouera. At
A. NJ. on the 9th commenced paying out the
cable, and having steered too far to the east all of
the Gulf line was exhausted, and nineteen miles
of the Punta Rassa (nOt Rosa) cable was used to
complete the connection. Precisely tWenty-four
hours after leaving Chorrera the Narva arrived
| at the buoy OH Key West, when preparations
! were at once made to splice the ends. The
| NarVa accordingly moved slowly for the Dur-
| pose OF drawing 10 the "slack,n when the cable
| parted about half mile distant from the stern
| of the steamer. Several days were spent in
| attempts at graphing for the lost end, but
| without success, and the work was temporarily
| suspended In Consequence of severe weather.
| Finally, as our special telegram announced on
! the 18th instant, the end was found and the
splice effected. We are, therefore, in direct COM
municaton with Cuba.
THE EFFECT OF THa CABLES UPON OUR COMMERCE..
The successful laying of the cable between
| Cuba and Key West, followed as IN undouht-
edly will be by the prompt construction of the
| other cable 10 connect us with South America,
will open new epoch for the commerce of New
| York and New Orleans with the countries south
| Of the United States. The large trade of the
West Indies will then be, in a great measure,
diverted to our shores, or be transacted by
American merchants, who, by possessing supe.
