EXTENSION OF THE ELEC rRIC TEL

From The English Mcchahics' Magan,ne.1
The establishment of an electro telegraph
ic communication acfoss the Straits between
England and France has been for consider
able time toreseen, as one of The most natural
in the train Of consequences resulting from
the modern application of electricity 10 the
transmission Of intelligence between distant

electric impulse for thousands Of miles over

is doing could be nothing in The nature

'efficacious il carried under The earth, or even
under water; granted always, what no one
has been heard 10 dispute, that it is IN the
power of art to protect the wire from what
ever antagonislic influences it may be expos
sed to when laid down under earth or water.
Trials of submerged lines of wire had in fact,

The newspapers say that they have obtained
"the exclusive right of electric communica-
lion between this country and France for ten
years" We do not well see how this can
be, looking at the legal difficulties in the way
but we are sure that no reward they can have
secured 10 themsels es will be too great for
the prodisious advantages which lhey have
secured by their individual exerlions, not on.
