TIES ATLANTIC' TELEGRA.PII COMP&NY•

We have been favoured by the directors of the above
company with a series of reports received from the com-
manders of the Atlantic Telegraph squadrons, also from
the engineer-in-chief and assistant engineers, Mr. Wild-
man, electrician to the company, Professor Morse, and
Professor Thomson, of Glasgow College, on the subject
of the recent experiment of laying down the cable, together
with the causes which have led to its temporary failure.
The concluding document, as will be seen, is a copy of
a letter received from the commanders of the American
ships engaged in, this service. The directors state that a
vast number of suggestions are daily received, which are
undergoing careful examination by persons capable, of
judging of their merits; and the utmost confidence is
expressed in the final success of the enterprise :

Gentlemen, We, the nndersigned commanding angers of the
several ships composing the Atlantic Telegr4ph Sqma Iron, have great
pie isure in expresiag our opinions with reference to the Attantie
Telegraph.
We are of opinion, drawn from our several observations and exre-
rience, that no obstacles of a nautical or physical character exist in
the way of the enterprise, and that the effisiency of the form of cable
adopted by the company is in every way a iaptel to its mission.
With regard to tin s machinery, we are of opinion that the form of
controlling-Power adopted, and the mode of lubricating and adjusting
the bra,ies, a ?mit of very great improvement.
We are thorou:shly-convinced, from the soundings made by Lieut
Berryman, U.S.N , on the plateau between Newfaundiand and
Ireland, subsequently confirmed by Lieut. Dayman, Pa.N., and the
investigations of Lieut. Mancy, United St ites Ob,erva ory, and from
our own nautical experhmee, that no under or surface, current exists
between these points to interfere with the successful laying of your
cable.
We all agree in th.nk'ng that no farm of submarine telegraph
cable could be devised more suitable in every respect to the o'sject
intendei to be accomplish d; that lightne,s, touchness, and
firAlbilt,r adapt it in every way for the purp :se of being laid
between I,Livfoundland and Ireland, and we are unwilling to recom-
mend its modifl?atien or alteration. We are als sof opinion that no
neural obstacles exist to prevent its being successfully laid between
those points, and our views as to the future :.respects of your enter-
prise are sanguine. We have the honour to be, gentlemen, yoni s
fsithfolly,

Dear Sir,—Tn answer :to ysur no'e, rerrissting ms to sign the
accompanying statement addressed to the Directors of the Atlantic
Telegraph Company, as my name is mentioned, I would rather not
append my signature.
Tnis is my only reason, and I entirely concur in the opinions
expressed therein.—Believe me, dears r, ycurs trif y,

as
Gentlemen,—We, the undersigne I, who have been engagrel
engineers daring the constrneion, shipment, and subinersioa of the
Atlantic cable, bag to submit t 3 you our judgment as to its fitness
forthe object for which it was intended, in regard to materia ,
dimen-
and stricture.
We consid r it to ba so eminently suited for laying in deep water
that we cannot suggest any improvement in it 4 form and construc-
tion, and do not recommend that any change whatever should be
made in the manufacture of any further 7' le for. . crossing the
Atl •ntic.
•

The outer covering being conitosed of strands of iron or wire,
instead of single Fires, as in former cable 4, g'vesi such flexibility to
the rope as almist to prevent the possibility of kinks c ctarring in
the paying out, if the cave is properly cored, while the strength
with an equal weight of metal, h also increased.
In case of a broken wire passing into the paying-out machine no
damage is done, while with the solid wire it sometimes unravels and
occasions serious inconvenience.
The cenduciing wire being also formed of a strand of copp r wires,
the chance :of continnly being loot is the circuit is redaccd to a
minimum from the improb ibility of any flaw or weakness occurring
in more than one of the seven w res at the same place —We are,
gentlemen, yours faithfully,

(No. 3.)
London, Aug. 21, 1557.

Gentlemen,—We, the un lersigned, have pleamre in reporting to
you that every experiment which we have made upon the cable,
every test to which we have sabjected it, both for it 3 insulating an i
conducting power;has uniformly resulted in demonstrating the per-
fact fitness of the cable for its office.
The treble covering of gaits percha so entirely provides for the
remote possibility of accidental di A occurring in either the first
second coat, that all risk of defective insulation is thus avoile 1.
Experiments ma 'e with a short length had previously proved that
an hydraulic pressure of five tons to the square iacir in no way
is j tared the insulation, and in the hi ;haat degree c mfirmatory of this
II the result of the mat recently made in the great ocean depths ; th,
actual pressure which a depth of water exceeding two miles had
exerted uprn its stractnre, produced not the slightest injury to the
insulation of the submerged portion o! our cable, while the low tem.
perature by which it was then surrounded produced, a; had been
nticipated, a distinctly Lend' _dal effect on the electriza: coudition of

the gotta percha.
ForA cable of great length necessarily lim;ted to a single conductor,
we cannot anzgest, on electrical or other ground•, any improvement
upon the form adopted by the company.—We are, gentleman, yours
faithfully,
