616 EUROPEAN SUBMARINE TELEGRAPHS.
laid some three miles apart across the channel, and near the
shore they are connected together in one great cable as represented by fig. 10. The shre ends are made as seen in the
figure, being composed of seven lesser cables, such as are laid
in the sea, twisted together, forming one of great strength and
size. It is intended to lay the other four across the sea whenever the business requires them.
PRINCE EDWARD S ISLAND CABLE.
A submarine cable manufactured by Messrs. Newall & Co.,
as represented by fig. 11, was laid in 1852 between Prince
Edward's Island and New Brunswick, a distance of ten miles.
It worked successfully. This was intended as a part of the
telegraph, designed to run from Prince Edward's Island to
the island of St. Paul, or to the west coast of Newfoundland.

THE DANISH BALTIC SEA TELEGRAPH.
Fig. 12 represents the cable constructed for the Danish government and laid across the great belt of the Baltic sea. It
runs from Nyborg to Korsoe on the Island of Zealand, connecting there with the line to Copenhagen. This cable has three
electric wires well insulated and surrounded with an armor
of nine large iron wires. The cable completed the telegraphic
connection between Denmark and the other states of Europe,
and by another cable laid across the Sound in 1854, a connection was formed between Denmark, Norway and Sweden. It
was necessary that the cable laid across the belts of the Baltic should be very strong, because it was liable to be drawn
