there will be no reason to complain Of any defects
in this important particular. In the meantime the
electricians have been hard at work in their partcu
lar department and have succeed in telegraphing
word minute through length of twenty-five hun
dIed miles OF cable. This is great advance, when
compared with the comparatively slow transmission
of signals previous TO the departure OF
the expedition last August. In fact the rate of
transmission has been so far improved that it will
than double the receipts of the Atlantic Tele-
graph Company. This is one Of the most important
features of the enterprise, not merely matter of
pecunary interest for the company but for the IN
creased working value which it will give to the line
when laid Considering these points, the public at
tenton will be more earnestly enlisted in the
OF the next expedition than it in that of the last
Everything that human foresight can provide for
has been done 10 secure the accomplishment OF the
great work, and never were the prospects of q
triumphant accomplishment more cheering and
promising. Both the AgamemnOn and Niagara will
make trial of the machinery in the Channel before
their final departure for mid ocean, which will not
probably take place previous to the first week in
June next. The whole length of wire to be cooled
on board both ships is about Twenty-Five hundred
miles which will allow a surplus of between twelve
and thirteen hundred over and above the actual dis
lance between the two points of connecton-that is
between Trinity Bay Newfoundland, and Valencia
Bay, Ireland. This viii not only be sufficient for the
purpose, but will leave large excess after the com
petien of the work, and should not be surprised if
there were some seven or eight hundred miles moro
than the actual length requires. This however is a
matter that can only be settled by trial, and it must
therefore remain undetermined till the close OF the
next expedition.
The coiiing of the cable will be commenced in the
Niagara next Monday, the 10Th inst and will Oc
cupy altogether five or six weeks. Everything is in
readiness for its reception-the circles ere ready
and nothing remains to be done but &c place it on
board at once. There will be six circles this time
on account Of the increased length Mt the cable, OF
which there will betwo hundred mile, on board
of each ship. II is not yet decided which end of
the line the Niagara is to take, but there is some
talk Of her running to the coast of Ireland as she
had the shore line there last year. and there is some
doubt as to the justice of requiring her to go to
Newfoundland, and of being obliged to lay the shore
end there also. This is matter however, of little
moment and will be settled satisfactorily. Perhaps
the best way would be to send the shore end over in
small steeier as there is but ten miles OF it, and
have it laid before the arrival of the ship in Trinity
Bay, and thus the work would be greatly expedited,
and any difficulty in approaching the coast, should
there be rough weather, prevented However, as
have said, this is matter of but little moment any
way. The calculations at present that the cable
win be laid about the middle of June next, that
it will be in perfect working order by the 4th of July
