acting electrical Instruments, called re-
laws, the messages will be RENTED, with
out the intervention of clerks, to the chief
German towns. BY the adoption of this
plan, which will be rendered possible by
The excellence of The cable, and by the
possession of independent land-lines, great
Improvement will be effected in the trans
mission Of messages both as TO time and
accuracy. Each conductor Of the cable
is formed Of a copper strand weighing
1O7 lbs. per knot, and of q gutla percha
covering weighing $50 lbs. The tests of
the insulation of each wire were nearly
if not quite as high-a as those of the Allan
tic wire when it left England. Great
care has also been taken in the selection
of the copper, which was on The average
only about 7 per cent. inferior in electri-
cal properties to chemically pure copper.
Not many years since an inferiority of
about 20 per cent. was considered almost
unavoidable. Although the main cable
is as strong as the shore ends Of many
submarine lines, 20 miles Of cable of
more than twice the weight are placed
near the shores where greater risk occurs
of injury fIom anchors. This cable
would bear 40 tons strain, and is covered
with o double sheathing of iron the
outer mail being formed of small wire
ropes, laid round and round the main
cable. The total weight of the $40 miles
is about 1900 tons, an amount which
will bear comparison even with the total
weight Of each Atlantic cable, which, ex-
GLIDING the shore ends, is about 5000
tons. The contract for manufacture and
LAYING was let to the Telegraph COnstruc-
ton and Maintenance Company, and
Messrs. Forde and Fleming Jenkin have
superintendent the manufacture and sub
mersion, as engineers and electricians, on
behalf of Reuters Telegram Company.
THE "NoRTH ATLANTIC TELEGRAPH."-
During the last few months various ar
engagements for the immediate commence
ment Of this important undertaking lave
been negotiated and completed. It is
we'll known how strongly the North Allan
tic route, uid Iceland, commends itself
from the great natural advantages it pos
sessps in the subdivision of the cable into
four short and manageable sections, the
longest of which does not much exceed
$40 miles. The North Atlantic route
possesses, however, other features of in
terest which equally command attention
for instance, the opening Of new and
more direct and speedy Geographic COM
munications with the great circuits of
Northern Europe. Mr.. Holmes, the en-
gineer Of the company, has at length
completed these important arrangements,
which will ultimately afford advantages in
connection with Indian traffic at present

systems of the respective Governments of
Denmark, Norway, Sweden and Russia
are all interested in these new and impor-
tant traffic arrangements, and the neces-
sary moneys required to erect new and
independent lines through Norway, Dem
mark and Sweden, to be placed in spe-
cial and exclusive connection with the
cables to be immediately submerged be-
tween England and Denmark, and Den
mark and Norway, by the North Atlantic
Company, have been voted by the respec-
tive Governments, and these lines will
be Immediately carried out, so as to be
