I0----,r-. a. Atlantic reIesraph Expedition

Nianara- the Agameun"hI he
GorTon, and the POrcuPine, started nom ny
SaoI.h Sonnd at ten O'Clock on the morning Of
he IOth of June, for mid ocean, where the WORK |
oe submerging the Atlantic telegraph cable will |
\ commenced some time between the 10th and |
2Oth inst. The particular point selected Is m
Ion. 50 DEG. min. N, and 80 deg. is mln- W.
where the depth of the ocean Is 500 fathoms
The ships are to keep in company until they
arrive at this locality, to prevent the Posslblhty
of any DELAY when they reach their destination
Rv a Glance at the chart on the telegraph pla-
,cau Il will be seen that the point selected Is
fiftv miles nearer to the coast Of Newfoundland
tban il is 10 the coast of ireland; but as the
Niagara will be obliged to land the cable at the
head Of Trinity Bay, she viii have no adyan-
tage. That Bay is about sixty miles long, SO
that the spot chosen will be half way between
the points of connection.
The weather is as fine as could be wished,
and the expedition started under the most Ia
vorabe auspices
Ninety additional miles of cable have been
placed on the Niagara and Agamemnon during
The mast five DAYS, so there Is now on board
both ships 1870 miles, or little more than fifty
per cent on the distance between ireland and
| Newfoundland
Among the scientific men on the Niagara is
Lieutenant the Baron dc BOye, one of the Aids
Of the Grand Duke Constantine, High Admiral
of the Russian Navy.
MECHANICAL AND ELECTRICAL ARRANGEMENTS
PoR THE ExPEDTTIOs.
The following are the rules which have been
drawn up for the mechanical and electrical de-
partments while on the expedition:
First-In case the cable should break after a
definite amount-say $50 miles-had been paid
out from each snip, the ends are to be reunited
after recovering as much a. possible, and the
paving out is TO be renewed unless circumstan-
/ ces may have arisen to induce the engineer to
determine otherwise, especially in the event Of
/ a LARGER proportion of slack having been eX-
pended than was Teckoned on.
Second-If signals should fail TO be received
between the paying out ships, the engineers
will continue paying out for at least six hours,
and SO much longer as the electricians and en-
pineers may deem necessary and desirsble.
Third-fn case e,cctrietl signals fail as the
ships approach the land, without other evidence
of breakage, sounding at the time being not
deeper than 200 fsthOms the ships are TO go on
paving out and land the ends.
Fourth-In case the cable break after more
than two hundred and fifty miles have been paid
out from each ship, and before il has been pos
sibIe to reach soundings of two hundred fathOms,
the ships are to return to Queenstown for or
ders.
Fifth-The cable is to be united in lat 50 deg.
! min n, Ion. 80 deg. IS min. W.
Sixth-Aiter the cable has been successfully
laid, Mr.. Field is authorized to dispose of any
surplus cable that may remain, at the rate Of not
less than f75 (S375) per statute mile of l,75O
yards.
Seventh-After the cable is laid the machine
~ on board the United States steam fngate Nj
agara is 10 be taken on to New York, and tran
shipped from the Niagara on board q vessel
bound Tor the United Kingdom.
Our previous faith in the probable success Of
laying the telegraphic cable has been much
shaken by recent publications Letters written
on board the Niagara after the experimental
trip show that the experiments were far from
satisfactory to all, and that the cable parted nc
less than five tiues during the trip of three
days, the calamity occurring to both the old
and the new cable alike. The break in every
instance was on the AgamemnOn. The acci
dents could not be attributed to bad weather OIL
rough sea, as both were favorable.
A correspondent of the n. Y. Times on the
Niagara gives a long and minute account o
the experimental trip. The writer states tha
when the cable parted the third time there wal
no apparent cause, and that in heaving in th,
! cable it came up very much kiHked, unlaid, th'
wire covering round the cable almost straight
the cable rendered totally unfit for relayinl
again, and in condition utterly impossible Il
coil it away in the tiers or circles. The en-,
came aboard in perfect snarl, hard twisted
open strands, and terribly kinked.
The correspondent eonfesses that his conf
dence, heretofore firm and mistaken, is impair
ed The parties most interested, however, wer
more sanguine than ever, and the sailing of tn
feet is the best Of evidence of the confidence il
success felt by Capt. Hudson and his associates
May their highest hopes be fully realized.
We add the account of the two last breaking
of the cable from the letter TO the Times:
The night is foggy-st Al o'clock in the NOR
ming misty-yet calm and sea smooth We agaiI
run hawser to Agamemnon, and afterwards thi
/ cable. AT st she signal,zes, 'All ready for pay
inc out" Both ships then pay out, each one
quarter of a mile; the hawser is then cast of
the weather is now clear and the sea is smooth
both ships contine to pay out cable, and thu
electric spark through the cable constant anC
uninterrupted; the ships steer opposite direc
lions, and our distance IRON each other Is in
creasing; our speed st miles, the AgamemnOr
probably the sane, not less; the wheels owe

80 revolutions. At this point, say st miles ca
bic being out from the Niagara, the dynamo

} however, inetuated up to $3.50 pounds. Th'
cable was then checked from going out so fast
: at A NJ, the order was given to reverse th'
ships engine for the purpose Of attaching buoy
This buoy is large iron, made 26 feet long, and
l3 feet circumference; it is carried outsice. TG
this is attached chain-buoy rope-the Tele
graph Cable is, however, made fast to a rope
, After the cable had become attached to this i'm
mense buoy, the pressure Of the cable wa
greatly diminished. More was paid out, AM
the velocity much increased, the wheels revolv
ing at the rate of so revolutions The buol
! stood upright on the water very eOnspieuOusly
The second buoy was now made fast to the
cable at a distance of twenty fathoms from
the first buoy. This buoy is of wood. j
also worked beautifully; continued to pay
out eable-the ship at the same time go
ing ahead left the buoys considerable dis
tance of. It is beautiful weather and nearly
+ calm. The length Of the rope made fast 4

Of Telegraph cable was paid out after smal
r buoy was put on. When Just at the time wher
running finely over the wheels slight defec
tive place in cable was noticed coming along
, it, however, passed safely over and past tb,

and the stem # the ship. Three miles and 75C

was to take I'D the buoys. For this purpose ;
