THE ATLANTIC TELEGRAPH.

The operation of stowin=g the wire for a second
effort on bowel her Majesty's ship Agamemnon, in
Keyham basin, is now proceeding rapidly. An
extra place for deposit his been eons rooted on her
upper deck, abaft the foremast, capable of taking
2 1-sth miles each fl tke or layer. Here about 140
miles were deposited up to yesterday, Thursday
evesing, at an avera,ge of 27 miles a-day. It will
contain together 2eo miles, which forms the first
portion to be tail. The place of deposit last year,
in the hold,
mads the coil oval in one direction,
close to the kelson, an.l oval in the opposi'e direc-
tion above. A different arrangement prevails now ;
two additional bulkheads have been knocked away,
and the hold presents the appearance of a basin
perfectly circular in every part. The cone in the
centre is 12 feet 3 inches high, and has a diameter
of 10 feet at the base an 1 5 feet at the top, it will
be encircled by 1,050 miles of cable. The remain-
ing 150 milts are to be coiled on the orlop deck
where the heavy shore en:l was placed lets, year. A
new guard has been fitted for the Agamemnon's
stern, to prevent the cable from fouling the pro-
peller. Tae cage
previously used was weakened by
its proximity to the copper oa the ship's bottom,
which served as a negative to the iron. The gal-
vanic ac ion of sal:. water on it during the last
eight mouths has rendered it desirable to provide
a new one, which will not touch the surface until
the load line is reached. On ho trel the Niagara
the boats forward on the upper deck are to be re-
moved, and a snace prepared of 33 feet diameter,
equal to •he reception of from 170 t i 180 miles of
cable. Fur the appro ichiug trial the Atlantic
Telegraph Company appear to have ma de very
complete arrangements through their engineer-in-
chief, Mr. Bright, who has teen some days a,
Plymouth. The ceiling on hoard the Agamemnon
is superintended by Mr. Caneing, who assi-trd in
the operations last year, and who laid the cable
across the Gulf of St. Lawrence from New
en. Mr. Whitehouse,
foundiand to Cape Bret,
who completed the lines from Varna t
klava, and was charged with the first shipment
and fittings on board the Niagara, takes the saute
duty now, with the aid of C =ptain Kell, who wa,
engaged in lay 'ng the early Mediserranean lines.
Mr. Everett, of the Niagara, accompanied by Mr.
°Mold, one of the Compa iy's assistant wegineers
on the former occasiou, hts been entrusted with
the supervision of the experiments carried on at
the works of Messrs. Easton and Amos, under the
advice of Messrs. Penn, Field, and Lltyd, whom
the company have eonsulted upon the modifications
to be made in the paying oat to ichinery, and with
the coucurrence of Mr. Brigh-, teeir engineer, and
Mr. App ld, who invented, for a different purpose,
the form of brake to be used. The staff of
telegraphic clerks engaged last year has been re-
tained, and some of them under the guidance of
Mr. Whitehouse, the tlectrician, are perfecting
themselves in their future employment by trans-
mitting and receiving, through the 2,630 miles of
wire now at Plymouth, the class of messages antici-
pated on the closer junction of England with the
United States and the continent of America.

ANCHORS FOR THE GREAT EASTERN.—On Tuesday
and Wednesday two of Trotman's parent anchors, each
weighing 5 tons 12 cwt., and intended for the Great
Eastern steam-ship, were tested by the powerful h) drau-
lie machinery at Woolwich Dockyard, in presence of the
patentee and numerous visitors, comprising the Marquis
of Stafford, Capt. Stopford, Lieut.-Col. Maude, R.A.,
and several idieutifia gentlemen. As it is requisite that
the anchors for the Great Eastern shall be of enormous
strength, they were submitted to a pressure amounting
to 45 per cent. over the proof required by the Admiralty.
At a pressure of 20 tons the deflection was a quarter of
an inch, and the strain being gra-lually increased to 90
ions, the extreme dell ction amounted to 1i inches. At
this strain Mr. Rice and Mr. Peake, master shipwrights,
Mr. Atherton, chief engineer, and Mr. Nodiali, master
of the Fiegard, who conducted the experiments, cau-
tioned all present to keep clear of the machinery, lest an
accident Fhould result from the sudden flying of the metal.
With theconwseintht ofa tension of
100ntee the machinery wit%
tons,
the most intense
interest prevailing to ascertain the result. Both anchors
stood this extraordinary test without the least indication
of giving way, a result highly fay, urable to the manu,
tacturers, Messrs. Wood and Co., of Liverpool.

Mr. Smiles, Secretary to Mr."Eborall, General Man-
ager of the South Eastern Railway Company, had at
interview with Mr. Fitzgerald, yesterday, at the
Foreign office, on the subject of foreign passports.
There was a concert a day or two since in the Austrian
State Lunatic Asylum, and Staudigl, the once celebrated
4inger, sang the "Chapel in the Wood," by Schubert,"
:o the great delight of his fellow patients.
