THE INQUEST
Expert Trials--Expert Evidence
The great historical sea-line having collapsed, some of the foremost of
the electrical profession were called in--first to determine the nature
of the interruption with a view to possible remedy, next to elicit _the
cause_.
_Expert Opinions on the Failure._--Mr. Cromwell Fleetwood Varley, the
electrician to the Electric Telegraph Company, Mr. E. B. Bright, the
chief of the "Magnetic" Company; and Mr. W. T. Henley, the well-known
telegraph inventor, were severally requested by the "Atlantic" Company
to report on the subject in conjunction with Sir Charles Bright and
Professor Thomson.
First of all the dead line was subjected to a series of tests. For this,
resistance-coils and Messrs. Bright's apparatus for ascertaining the
position of a fault were employed. There was every evidence of a serious
electrical leakage about 300 miles from Valentia, but there did not
appear to be any fracture in the conductor, as exceedingly weak currents
still came through fitfully. According to the above location, the main
leak through the gutta-percha envelope was in water of a depth of about
two miles. At that time means were not devised for grappling and
lifting a cable from such depths. But from independent tests by Thomson
and Bright, it appeared likely that the Valentia shore end was also
especially faulty. Accordingly, it was underrun from the catamaran-raft
(previously used in 1857) for some three miles, but, on being cut at the
farthest point at which it was found possible to raise the cable, the
fault still appeared on the seaward side. The idea of repairs had,
therefore, to be abandoned, and the cable was spliced up again.
The conductor being again intact, efforts were made to renew signals
with the curb-key recently invented by Messrs. Bright. By means of this,
currents of opposite character were transmitted so that each signaling
current was followed instantly by one of opposite polarity, which
neutralized, by a proportionate strength and duration, all that remained
of its predecessor. Though this was the right principle on which to
work, the "patient" was too far gone, and all efforts proved unavailing;
for signaling purposes the poor cable was defunct.
Having dealt with the nature of the interruption, we now come to the
_cause_. It was first of all abundantly clear from the station-diaries
kept by the electricians at Valentia and Newfoundland, and by other
irrefragable evidence, that when the laying was completed, and the cable
ends were handed over to them from the ships on August 5th, all was in
good working order.
The authorities were unanimous in their opinion. Mr. C. F. Varley
declared that "had a more moderate power been used, the cable would
still have been capable of transmitting messages." In giving extra force
to the above opinion, Mr. Varley described an experiment he had made on
the cable in conjunction with Mr. E. B. Bright:
We attached to the cable a piece of gutta-percha-covered wire,
having first made a slight incision, by a needle-prick, in the
gutta-percha to let the water reach the conductor. The wire was
then bent, so as to close up the defect. The defective wire was
then placed in a jar of sea-water, and the latter connected with
the earth. After a few momentary signals had been sent from the
five-foot induction-coils into the cable, and, consequently into
the test-wire, the intense current burst through the excessively
minute perforation, rapidly burning a hole nearly one-tenth of an
inch in diameter, afterward increased to half an inch in length
when passing the current through the faulty branch only. The burned
gutta-percha then came floating up to the surface of the water,
while the jar was one complete glow of light.
Professor Hughes, the inventor of the type-printing telegraph, and,
subsequently, of the microphone, considered that "the cable was injured
by the induction-coils, and that the intense currents developed by them
were strong enough to burst through gutta-percha." Professor Wheatstone
gave a similar opinion.
Some one inquired of the electrician whether, if any one touched the
cable at the time when the current was discharged from the
induction-coil, he would receive a shock sufficiently strong to cause
him to faint. It was admitted in reply that "those who touched the bare
wire would suffer for their carelessness, though not if discretion be
exercised by grasping the gutta-percha only."
The chairman of the company (the Right Honorable J. Stuart Wortley,
M.P.), in the course of a deputation to Lord Palmerston later on,
stated that "far too high charges of electricity were forced into the
conductor. It was evidently thought at that time by certain electricians
that you could not charge a cable of this sort too highly. Thus they
proceeded somewhat like the man who bores a hole with a poker in a deal
board; he gets the hole, to be sure, _but the board is burned in the
operation_."
Professor Thomson (now Lord Kelvin), writing in 1860, expressed the
following opinion:
It is quite certain that, with a properly adjusted
mirror-galvanometer as receiving-instrument at each end, twenty
cells of Daniell's battery would have done the work required, and
at even a higher speed if worked by a key devised for diminishing
inductive embarrassment; and the writer--with the knowledge derived
from disastrous experience--has now little doubt but that, if such
had been the arrangement from the beginning, if no induction-coils
and no battery-power exceeding twenty Daniell cells had ever been
applied to the cable since the landing of its ends, imperfect as it
then was, _it would be now in full work day and night, with no
prospect or probability of failure_.[50]
Summing up the _cause_ of the untimely ending to the ill-used cable,
perhaps the concisest verdict would be, in mechanical-engineering
_parlance_, that "high-pressure steam had been got up in a low-pressure
boiler."
PART III
INTERMEDIATE KNOWLEDGE AND ADVANCE
CHAPTER XII
OTHER PROPOSED ROUTES
North Atlantic Telegraph Project--Exploring Expedition--Ice
Troubles--South Atlantic Telegraph Project.
The gradual failure of the 1858 cable after a short period of working,
and the slow rate at which messages were capable of being transmitted,
naturally deterred capitalists from providing the means for another
cable of such length in deep water.
Several schemes, however, for a fresh line on other routes were brought
forward; and there was an alternative route between Great Britain and
America by which the transmission of the electric current could be
subdivided into four comparatively short sections. This was known in
1860 as the North Atlantic Telegraph project, in which the route was
from the extreme north of Scotland to the Faroe Islands, thence to
Iceland; from there to the southern point of Greenland, and so on to
Labrador or Newfoundland. The distances were (varying a little according
to landing-places selected) approximately:
Miles
From the north of Scotland to Faroe Islands 225
From the Faroe Islands to Iceland 280
From Iceland to Greenland, S. W. Harbor 700
From Greenland to Labrador 550
----
Total 1755
[Illustration: FIG. 32.--The North Atlantic Telegraph Project, 1860.]
From the electrician's point of view, these subdivisions were extremely
favorable as compared with the long continuous length entailed by an
Atlantic cable between Ireland and Newfoundland. Then, again, the
soundings (except for a section between Greenland and Labrador) did not
yield anything approaching the more southern depths. But against these
obvious advantages there was the engineering objection--which at first
seemed insurmountable--that the Greenland coast was bound up by ice for
a great part of the year, in addition to the risk of injury to the cable
from the grounding of icebergs. This latter was of less moment, for it
could be provided against by keeping the cable when approaching shore in
the middle of any inlet, and thus away from the shallow sides where the
icebergs "ground." There was also the probable difficulty of obtaining a
trained staff to work a line when laid to such inhospitable regions.
However, having regard to the anxiety exhibited by many to get to the
North Pole, this did not present an insuperable obstacle.
This bold project, with a route across the coldest and iciest regions of
the Atlantic, was originally brought to the notice of the Danish
Government by Mr. Wyld, the geographer, even before the Atlantic
Telegraph Company had been established. It was again introduced in a
different form by Colonel T. P. Shaffner, an American electrician of
some note. Colonel Shaffner made a strong case of the series of short
stages geographically afforded by the North Atlantic deviation. After
the 1858 cable had ceased working, to back up his belief in the
advantages of the route, which he characterized as having "natural
stepping-stones which Providence had placed across the ocean in the
north," he actually chartered a small sailing vessel, and, with his
family on board, put forth from Boston on August 29th, 1859, for the
purpose of making the preliminary survey. He landed in Glasgow in
November of that year, and presented to the public the results of his
voyage. During the voyage, Colonel Shaffner sounded the deep seas to be
traversed between Labrador and Greenland and between Greenland and
Iceland. His first object was to convince the public that there were no
insuperable difficulties in the way. He found a warm supporter in Mr. J.
Rodney Croskey, of London, who advanced the "caution" money to the
Danish Government for the concessions requisite in the Faroes, Iceland,
and Greenland.[51]
On May 15th, Lord Palmerston granted an audience to an influential
deputation, headed by the Right Honorable Milner Gibson, M.P., and four
other members of the House of Commons, to solicit the assistance of
Government in sending out ships and officers to make the necessary
official survey for ascertaining the practicability of the proposed
route. The Premier appeared fully to appreciate the advantages of the
north-about scheme, and in a very short time the Admiralty were directed
to send out an expedition for the purpose of making the required survey.
The Admiralty selected for this duty Captain M'Clintock, R. N.,[52] an
officer of great experience in the navigation of the Arctic seas, and
H.M.S. Bulldog was placed under his command. This distinguished officer
was directed to take the deep-sea soundings, and he sailed from
Portsmouth on his mission in June, 1860. In the meantime, the promoters
of the enterprise purchased the Fox, the steam-yacht formerly employed
in the successful search for the remains of the Franklin expedition, and
fitted her out for the purpose of making surveys of the landing-places
of the respective cables. The Fox was placed under the command of
Captain Young,[53] of the mercantile marine, an officer well known for
his distinguished labors under M'Clintock in the Franklin search. At the
same time, Dr. John Rae, F.R.G.S., an intrepid Arctic explorer,
volunteered his services to join the Fox, and take charge of the
overland expeditions in the Faroe Isles, Iceland, and Greenland. Colonel
Shaffner, as concessionaire--besides two delegates on the part of the
Danish Government, Lieutenant von Zeilau and Arnljot Olafsson--also
accompanied the Fox expedition, to take part in the necessary surveys.
Before the departure of the Fox, which sailed on July 18, 1860, her
Majesty Queen Victoria, the Prince Consort, and other members of the
royal family, honored the enterprise by a visit to that vessel, while
lying off Osborne, and showed a lively interest in the details of the
expedition.
On the return of the expedition, Sir Leopold M'Clintock wrote a full
report to Sir Charles Bright, the consulting engineer of the project.
In this, Sir Leopold favored the route as perfectly practicable,
pointing out that the ice would not really prove a difficulty, and
strongly approving of the original intention of a land-line across
Iceland to Faxe Bay, "as by so doing you will avoid the only part of the
sea where submarine volcanic disturbances may be suspected."
The results of the voyages of H.M.S. Bulldog and the steam-yacht Fox
were brought before a crowded meeting of the Royal Geographical Society
on January 28, 1861. Sir Leopold M'Clintock then gave the first public
account of his numerous and careful soundings along, and in the vicinity
of, the proposed course of the cable, interspersed with many useful
remarks and hints as to ice, the best time for laying the line, etc., as
well as the probable sphere of volcanic action in and off the south of
Iceland. The above was followed by an exhaustive paper by Sir Charles
Bright, giving a synopsis of Captain Young's report on his voyage in the
Fox, including the examination of various estuaries and harbors, so as
to enable a decision to be arrived at as to the best landing-places, the
climatic conditions, etc.
From both sets of soundings it was shown that, as a rule, the bottom was
of ooze. Dr. Wallich, the naturalist of the expedition, had brought up
brightly colored starfish from depths of over a mile, whereas it had
previously been believed that nothing could possibly live under such an
enormous pressure of water.
[Illustration: FIG. 33.--The North Atlantic Exploring Expedition, 1860.]
Then came a highly instructive paper by Dr. Rae. He gave a number of
interesting particulars of his land surveys, the population, price of
food, wages, etc. He also described the ride of the Fox party across
Iceland, while making important suggestions as to the route for the
land-line with a view to avoiding the geysers.
Captain R. B. Beechey, R.N., afterward made a beautiful oil-painting of
the party, including some of the Eskimos on the occasion of landing to
explore the inland ice at Igaliko Fiord (see Fig. 33).[54]
At this time, however (1861), there was still too much discouragement
owing to the stoppage in working of the first Atlantic cable, and to
other causes with which we are about to deal. Moreover, there were those
who still feared the ice-floes; and in the end the public did not
respond sufficiently. Thus, after all, the "Grand North Atlantic
Telegraph" project, which had been worked out with so much trouble and
expense, was never actually realized.
* * * * *
Another scheme which attracted some attention about the same time was
described as the "South Atlantic Telegraph." This was for a long length
of cable between the south of Spain and the coast of Brazil, touching at
Madeira, the Canary Islands, Cape de Verde Isles, Don Pedro, and
Fernando de Noronha Isles on the way, and stretching out to the West
Indies and the United States. Then there was a project for a cable on an
intermediate route from Portugal to the Azores, and thence to America,
via Bermuda and the Southern States. Being, however, to a great extent
foreign in their scope, these latter schemes found little favor in this
country at the time. They have, however, since been realized in some
shape or form.
CHAPTER XIII
EXPERIENCE, INVESTIGATION, AND PROGRESS
The Red Sea Line--Government Inquiry--Electrical Standards and
Units--Further Cables--Improvements in Manufacture, Testing, and
Working--Completion of Pioneer Stage.
_The Red Sea Line._--Mr. Lionel Gisborne had obtained powers from the
Turkish Government to carry a telegraph-line across Egypt and lay a
cable down the Red Sea. The importance of this line to Great Britain led
the Government to give definite assistance.
The first portion of the proposed cable--from Suez to Aden, with
intermediate landings--was laid in 1859. The different sections broke
down one by one. They were all laid very taut, the slack in some cases
being less than one per cent, though the bottom was in certain parts
very uneven. The second portion of the line, from Aden to Kurrachee,
with intermediate stations, was laid during 1860, the slack working out
at 0.1 per cent only. Faults developed very quickly in all the sections
of both portions of the line. Apart from the small allowance for slack,
the type of cable adopted was of far too fragile a nature for some of
its rough, reef-like resting-spots; indeed, the undertaking was spoken
of as "like running a donkey for the Leger"! The promoters of this
enterprise, having neither specially qualified men nor the necessary
materials for carrying out repairs, were obliged to abandon it before
any commercial work had been effected. This was a most unfortunate line
in every way, for a complete message was never got through the entire
length, but only through each section separately. Nevertheless, until
quite recently, it cost Great Britain £36,000 per annum.
_Inquiry on the Construction of Submarine Telegraphs._--Aroused more
especially by the above failure, the Government, in 1859, before
undertaking further responsibility, resolved to thoroughly investigate
the construction of cables. It was also felt that the ultimate failure
of the Atlantic line was possibly due, in part, to weak joints and
general defects in the manufacture of the insulating envelope. This
committee--under the direction of the Board of Trade, with Captain,
afterward Sir Douglas, Galton, R.E., in the chair--devoted twenty-two
sittings (covering a considerable period of time) to questioning
engineers, electricians, professors, physicists, manufacturers, and
seamen, who had taken part in the various branches of cable-work and
whose knowledge or experience might throw light on the subject.
Investigations were instituted concerning the structure of all cables
previously made, and the quality of the different materials used, as to
special points arising during manufacture and laying, on the routes
taken, electrical testing, and on sending and receiving instruments,
speed of signaling, etc. Actual experiments were also made in connection
with this inquiry, to ascertain (1) the electrical and mechanical
qualities of copper, pure and alloyed; also of gutta-percha and other
insulating substances; (2) the chemical change in their condition when
submerged; (3) the effects of temperature and pressure on the insulating
substances employed; (4) the elongation and breaking strain of copper
wires; of iron, steel, and tarred hemp separately and combined; (5) the
phenomena connected with electrically charging and discharging
conductors; (6) methods of testing conductors and of locating faults;
besides the whole science and practise of cable-making and laying.
The report of the committee was not published till some time afterward.
It expressed a conviction that submarine telegraphy might be made sure
and remunerative in the future, based on the evidence adduced regarding
the proper manufacture and working of submarine telegraphs.
_Formulation of Electrical Standards and Units._--This inquiry was
shortly followed by an important paper before the British Association
for the advancement of science by Sir Charles Bright and Mr. Latimer
Clark (then in partnership), which put the practise of electrical
testing on a systematic basis, thereby considerably forwarding all
electrical work connected with submarine telegraphy. A committee was
formed shortly afterward, which gave the suggestions then brought
forward the seal of universal officialdom.
_Further Cables._--About this time a number of other cable enterprises
were set afoot, some in shallow water and others in comparatively great
depths. Though few of them were able to benefit by the information
obtained in the inquiry, they were, in the main, more or less
successful. These projects included cables between Malta and Alexandria,
besides others in the Mediterranean and elsewhere. Sir Charles Bright,
Mr. (afterward Sir C. W.) Siemens, Mr. Lionel Gisborne, and Mr. H. C.
Forde were mainly associated with them as engineers and electricians.
The line which met, however, with the most complete and lasting success
was the first cable to India, laid (by Sir Charles Bright) in several
sections along the Persian Gulf in 1863-'64. In this undertaking Messrs.
Bright & Clark (engineers to the Government) introduced a complete
system of electrical and mechanical testing. Every joint was, for the
first time, efficiently tested, and the insulated core submitted to a
hydraulic pressure representative of that which it would experience when
laid.[55] A formula was also arrived at by an elaborate series of
experiments for the effect of temperature on the insulation, which
showed how enormously the resistance of gutta-percha increased by
consolidation when submitted to the low temperatures of the bottom of
the ocean. Chatterton's compound had been already introduced for
adhering the gutta-percha envelope to the wires, as well as for
cementing together the different insulating coats; but Bright & Clark's
preservative composition for the iron armor was first used in this
enterprise. This mixture not only evades the oxidation that iron wires,
even when galvanized, are subject to, but resists the attacks of the
teredo and other objectionable animal life. Moreover, besides the type
of cable being eminently suitable, the manufacture was carried out with
extreme care and with all the advantage of experience and improved
methods.[56]
_Completion of Pioneer Stage._--With the successful termination of the
above enterprise, forming the first telegraphic connection between the
United Kingdom, Europe, and India, the science of constructing and
laying submarine telegraphs was pretty definitely worked out, and no
very striking departure has since been introduced. The pioneer stage
may, indeed, at this juncture, be said to have reached completion.
For this reason the rest of our narrative on the Atlantic cable will be
told more briefly--though at greater length than the contents of this
chapter, recounting only the stepping-stones to what was to follow.
PART IV
COMMERCIAL SUCCESS
CHAPTER XIV
THE 1865 CABLE AND EXPEDITION
Fresh Efforts and Funds--The Contractors' Share--Design and
Construction--Provisions for Laying--S.S. Great Eastern--Sailing
Staff--Landing the Irish End--Another Bad Start.
_Fresh Efforts and Funds._--Though their cable had ceased to work, the
Atlantic Telegraph Company was kept alive by the promoters.
In 1862 the Government was prevailed on to despatch H.M.S. Porcupine to
further examine the ocean floor 300 miles out from the coasts of Ireland
and Newfoundland, respectively.
It took a considerable time to raise the full amount of capital required
for another Atlantic cable, for this could only be done gradually. The
great civil war in America stimulated capitalists to renew the
undertaking. One of the main advantages adduced was, on this occasion as
before, the avoidance of misunderstandings between the two countries.
Another--intended by Mr. Cyrus Field as a special inducement to his
fellow countrymen--was the improvement of the agricultural position of
the United States, by extending to it the facilities already enjoyed by
France of commanding the foreign grain-markets.[57] On this account the
project was warmly supported by John Bright and other eminent
free-traders.
Mr. Field, however, met with as little success in obtaining pecuniary
support in the States as he had in connection with the previous line.
His brother, Mr. H. M. Field, writes:
The summer of this year (1862) Mr. Field spent in America, where he
applied himself vigorously to raising capital for the new
enterprise. To this end he visited Boston, Providence,
Philadelphia, Albany, and Buffalo, to address meetings of merchants
and others. He used to amuse us with the account of his visit to
the first city, where he was honored with the attendance of a large
array of "the solid men of Boston," who listened with an attention
that was most flattering to the pride of the speaker addressing
such an assemblage in the capital of his native State. There was no
mistaking the interest they felt in the subject. They went still
further; they passed a series of resolutions, in which they
applauded the projected telegraph across the ocean as one of the
grandest enterprises ever undertaken by man, which they proudly
commended to the confidence and support of the American public.
After this they went home feeling that they had done the generous
thing in bestowing upon it such a mark of their approbation. _But
not a man subscribed a dollar._
In point of fact, as before, the cable of 1865--as well as that of
1866--was provided for out of English pockets. Let us now substantiate
this statement by a glance at events. The late Mr. Thomas Brassey was
the first to be appealed to in England, and he supported the venture
nobly. Then Mr. Pender[58] was applied to, and here also substantial aid
was forthcoming. Both these gentlemen had joined the board of the
Telegraph Construction and Maintenance Company, which had just been
formed (in April, 1864) as the result of an amalgamation of the
Gutta-Percha Company and Messrs. Glass, Elliot & Co. Mr. Pender, who had
been largely instrumental in effecting this combination, became the
first chairman.
_The Contractors' Share._--Shortly after the first Atlantic cable was
laid, Messrs. Glass, Elliot & Co. availed themselves of the services of
Mr. Canning and Mr. Clifford, whose engagements on Sir Charles Bright's
staff for the "Atlantic" Company had terminated. Thus, with an
additional staff of electricians, they had placed themselves in a
position to undertake direct contracts for laying, as well as
manufacturing, submarine telegraphs. They had, indeed, carried out work
of this character in the Mediterranean during the year 1860; and on the
amalgamation of the two businesses above mentioned into a limited
liability company, their position was still further strengthened.
The capital raised for the new cable by the Atlantic Telegraph Company
was £600,000; and, by agreeing to take a considerable proportion of
their payment in "Atlantic" shares, the contractors practically found
more than half of this amount. In the result, the undertaking became a
contractors' affair from first to last.
_Design and Construction._--It will be seen that the new cable was to be
an expensive one as compared with that of 1857-'58. It was the outcome
of six years' further experience, during which several important lines,
referred to in the last chapter, had been laid. It also followed upon
the exhaustive Government inquiry to which allusion has been made.
[Illustration: FIG. 34.--The Main Cable, 1865-'66.]
The actual type adopted (Fig. 34), on the recommendation of Sir Charles
Bright and other engineers who were additionally consulted, was much the
same in respect to the conductor and insulator--300 pounds copper to 400
pounds gutta-percha per nautical mile--as that which the former had
suggested for the previous Atlantic line. This combination for the
length involved was based on Professor Thomson's law for the working
speed of a cable, as depending inversely on the resistance of the
conductor as well as on the electrostatic capacity of the core. The
armor consisted of a combination of iron and hemp, each wire being
enveloped in manila yarns. The object of incasing the separate wires in
hemp was (1) to protect them from rust due to exposure to air and water,
and (2) to reduce the specific gravity of the cable, with a view to
rendering it more capable of supporting its own weight in water. This
form of cable, bearing a stress of about eight tons,[59] and suspending
eleven miles of itself, was considered by most of the authorities at
that period to perfectly fulfil the conditions required for deep-sea
lines.[60] The claims of light hempen cables, without any iron, had been
urged for meeting the difficulty of lay and recovery in deep water; and
this type formed a sort of compromise, its total diameter being 1.1
inch, weighing 1 ton 16 hundredweight in air, and only 14 hundredweight
in water. The shore end was to have a further outer sheathing of twelve
strands, each strand containing three stout galvanized-iron wires of No.
2 B.W.G., bringing the weight up to 20 tons per mile. This was to be
joined on to the main deep-sea type by a gradually tapering length of
twenty-five fathoms.
_Arrangements for Laying._--It was determined that this time the cable
must be laid in one length, with the exception of the shore ends, by a
single vessel. There was but one ship that could carry such a cargo.
This ship was the Great Eastern, the conception of that distinguished
engineer, Isambard Kingdom Brunel. She was in course of construction by
the late Mr. Scott Russell at the time of the first cable, and it was a
subject for regret that she was not then available. An enormous craft of
22,500 tons, she did not prove suitable at that time as a cargo-boat;
and the laying of the second Atlantic cable was the first piece of
useful work she did, after lying more or less idle for nearly ten
years.[61] It is sad to think of the way this poor old ship was
metaphorically passed from hand to hand. Even at this period three
separate companies had already been formed one after another to work
her. As promoter and chairman of one of these, Mr. (afterward Sir
Daniel) Gooch took an active part in arranging for her charter on this
undertaking, and it was in this way that he became a prominent party in
the enterprise.
All the cable machinery was fitted to the Great Eastern, on behalf of
the Telegraph Construction Company, by Mr. Henry Clifford to the designs
of Mr. Canning and himself. It was constructed and set up by the famous
firm of engineers, Messrs. John Penn & Son, of Greenwich. In the main
principles the apparatus employed was similar to that previously adopted
in 1858 on the Agamemnon and Niagara. There were, however, several
modifications introduced, as the result of the extra experience gained
during the seven years' interval. The main point of difference was the
further application of jockeys to the paying-out gear in a more complete
form.
As it was not practicable to moor so enormous a vessel off the works at
East Greenwich, the cable had to be cut into lengths and coiled on two
pontoons, and thence transferred to the big ship.
[Illustration: FIG. 35.--The Great Eastern at Sea.]
_Landing the Irish End._--At length all the cable having been
manufactured and shipped from the Greenwich works, the Great Eastern,
under the command of Captain (later Sir James) Anderson,[62] left the
Thames on July 23, 1865, with a total dead weight of 21,000 tons, and
proceeded to Foilhommerun Bay, Valentia. Here she joined up her cable to
the shore end, which had been laid a day earlier by S.S. Caroline, a
small vessel chartered and fitted up for the purpose. The great ship
then started paying out as she steamed away on her journey to America,
escorted by two British men-of-war, the Terrible and the Sphinx.
_The Sailing Staff._--On behalf of the contractors, Mr. (afterward Sir
Samuel) Canning was the engineer in charge of the expedition, with Mr.
Henry Clifford as his chief assistant. As we have seen, both these
gentlemen had been engaged with Sir Charles Bright on the first line,
besides having much experience in mechanical engineering as well as in
cable work. On the contractors' engineering staff there were also Mr.
John Temple and Mr. Robert London. Mr. C. V. de Sauty served as chief
electrician, assisted by Mr. H. A. C. Saunders and several others. By
arrangement with the Admiralty, Staff-Commander H. A. Moriarty, R.N.,
acted as the navigator of the expedition. Captain Moriarty was possessed
of great skill in this direction, a fact which had been made clear in
the previous undertaking.
[Illustration: FIG. 36.--Cable and Machinery aboard S.S. Great Eastern.]
The Atlantic Telegraph Company was represented on board by Professor
Thomson and Mr. C. F. Varley as electricians, the former acting mainly
as scientific expert in a consultative sense. Mr. Willoughby Smith, the
electrician to the Gutta-Percha Works, was also on board at the request
of the contractors, though holding no exact official position. Both Mr.
Field and Mr. Gooch accompanied the expedition, the former as the
initial promoter of the enterprise, and the latter on behalf of the
Great Eastern Company. Representing the press there were also on board
Dr. (afterward Sir W. H.) Russell, the well-known correspondent of The
Times, as the historian of the enterprise, and Mr. Robert Dudley, an
artist of repute, who produced several excellent sketches of the work in
its different stages for the Illustrated London News.
_A Bad Start._--Unfortunately trouble soon arose. The first fault
declared itself the day after starting, when eighty-four miles had been
paid out. It was decided to pick up back to the fault, which was
discovered after ten and a half miles had been brought on board. A piece
of iron wire was found to have pierced the cable diametrically, so as to
make contact between the sea and the conductor. The faulty portion was
cut out, and the paying out resumed as soon as the cable was spliced up
again. On July 29th, when 716 miles had been laid, another and more
serious fault appeared. The arduous operation of picking up again
commenced. After nine hours' work the fault was safe inboard, and the
necessary repair effected. On stripping the cable another piece of iron
wire was discovered sticking right through the core. Anxiety and
misgivings were now felt by all on board, for it seemed that such
reverses could only be attributed to malevolence. On August 2d yet a
further fault was reported; they were now two-thirds of the way across,
1,186 miles of cable being already laid. Again they had to pick up, and
this time in a depth of 2,000 fathoms. One mile only had been recovered,
when an accident of some kind happened to the machinery. The great ship,
having stopped, was at the mercy of the wind and swell, and heavy
strains were brought on the cable, which consequently suffered badly in
two places. Before the two injured portions could be secured on board
the cable parted and sank. Mr. Canning at once decided to endeavor to
recover the cable, notwithstanding the fact that it lay in 2,000
fathoms. After maneuvering in this way for about fifteen hours, 700
fathoms of rope had been hove in, when one of the connecting links gave
way, and all beyond it sank to the bottom. The work was recommenced with
hempen ropes, two miles farther west, in a depth of 2,300 fathoms, and
on August 8th the cable was again hooked; but when raised to within
1,500 fathoms of the surface, yet another connecting link parted, the
strain being about nine tons. Two more attempts were made, but both were
doomed to end in failure. The store of rope being now quite exhausted,
the work had to be abandoned, and on August 11, 1865, the fleet of ships
parted company to return home--shattered in hopes as well as in ropes!
CHAPTER XV
SECOND AND SUCCESSFUL ATTEMPT
Further Funds--Fresh Provisions--New Picking-up
Machine--Staff--Cable-Laying again--Success.
The results of the last expedition, disastrous as they were from a
financial point of view, in no wise abated the courage of the promoters
of the enterprise. During the heaviest weather the Great Eastern had
shown exceptional "stiffness," while her great size and her maneuvering
power (afforded by the screw and paddles combined) seemed to show her to
be the very type of vessel for this kind of work. The picking-up gear,
it was true, had proved insufficient, but with the paying-out machinery
no serious fault was to be found. The feasibility of grappling in
mid-Atlantic had been demonstrated, and they had gone far toward proving
the possibility of recovering the cable from similar depths.
_Further Funds._--To overcome financial difficulties, the Atlantic
Telegraph Company was amalgamated with a new concern, the Anglo-American
Telegraph Company, which was formed, mainly by those interested in the
older business, with the object of raising fresh capital for the new and
double ventures of 1866. The ultimate capital of this company amounted
(as before) to £600,000. In raising this, Mr. Field first secured the
support of the late Sir Daniel Gooch, M.P., then chairman, and
previously locomotive superintendent of the Great Western Railway
Company, who, after what he had seen on the previous expedition,
promised, if necessary, to subscribe as much as £20,000. On the same
conditions, Mr. Brassey expressed his willingness to bear one-tenth of
the total cost of the undertaking. Ultimately, the Telegraph
Construction Company led off with £100,000, this amount being followed
by the signatures of ten directors interested in the contract (as
guarantors) at £10,000 apiece. Then there were four subscriptions of
£5,000, and some of £2,500 to £1,000, principally from firms
participating in the subcontracts. These sums were all subscribed before
even the prospectus was issued or the books opened to the public. The
remaining capital then quickly followed.
The Telegraph Construction Company, in undertaking the entire work, were
to receive £500,000 for the new cable in any case; and, if it succeeded,
an extra £100,000. If both cables came into successful operation, the
total amount payable to them was to be £737,140. In fact, it was, if
possible, even more of a contractor's enterprise than that of 1865.
It was now proposed not only to lay a new cable between Ireland and
Newfoundland, but also to repair and complete the one lying at the
bottom of the sea. A length of 1,600 miles of cable was ordered from the
contractors. Thus, with the unexpended cable from the last expedition,
the total length available when the expedition started would be 2,730
miles, of which 1,960 miles were allotted to the new cable, and 697 to
complete the old one, leaving 113 miles as a reserve.
_Fresh Provisions._--The new main cable was similar to that of the year
before, but the shore-end cable determined on in this case was of a
different description. It had only one sheathing, consisting of twelve
contiguous iron wires of great individual surface and weight; and
outside all a covering of tarred hemp and compound. That part of the
line which was intended for shallow depths was composed of three
different types. Starting from the coast of Ireland, eight miles of the
heaviest was to be laid, then eight miles of an intermediate type, and
lastly fourteen miles of a lighter type, making thirty miles of
shoal-water cable on the Irish side. Five miles of shallow-water cable,
of the different types named, were considered sufficient on the
Newfoundland coast.
The previous paying-out machinery on board the Great Eastern was altered
to some extent by Messrs. Penn to the instructions of Messrs. Canning &
Clifford. Though different in detail, the main improvement over the 1865
gear consisted in the fact that a 70-horse-power steam-engine was fitted
to drive the two large drums in such a way that the paying-out
machinery, as in 1858, could be used to pick up cable during the laying,
if necessary, thereby avoiding the risk incurred by changing the cable
from the stern to the bows. This addition of Penn trunk-engines, as well
as the general strengthening of the entire machinery, was made in
accordance with the designs of Mr. Henry Clifford.
[Illustration: FIG. 37.--The Picking-up Machine, 1866.]
The picking-up machinery forward (Fig. 37) after the previous expedition
was considerably strengthened and improved with spur-wheels and
pinion-gearing. It had two drums worked by a similar pair of
70-horse-power engines. This formed an exceedingly powerful machine, and
reflected great credit on those who devised and constructed it.
Similar gear was fitted up on board the two vessels--S.S. Medway and
S.S. Albany--chartered to assist the Great Eastern.
For the purpose of grappling the 1865 cable, twenty miles of rope were
manufactured, which was constituted by forty-nine iron wires, separately
covered with manila hemp. Six wires so served were laid up strandwise
round a seventh, which formed the heart, or core, of the rope. This rope
would stand a longitudinal stress of 30 tons before breaking.
In addition, five miles of buoy-rope were provided, besides buoys of
different shapes and sizes, the largest of which (Fig. 38) would support
a weight of twenty tons. As on the previous expedition, several kinds of
grapnels were put on board, some of the ordinary sort, and some with
springs to prevent the cable surging, and thus escaping while the
grapnel was still dragging on the bottom; others, again, were fashioned
like pincers, to hold (or jam) the cable when raised to a required
height, or else to cut it only, and so take off a large proportion of
the strain previous to picking up. Most of this apparatus was furnished
by Messrs. Brown, Lenox & Co., the famous chain, cable, anchor, and buoy
engineers, several of the grapnels being to their design, as well as the
"connections."
The propelling machinery of the Great Eastern had similarly received
alteration and improvement in the intervals of the two expeditions.
Moreover, the screw propeller was surrounded with an iron cage, to keep
the cable and ropes from fouling it, as had been provided for the
Agamemnon and Niagara in 1857.
[Illustration: FIG. 38.--Buoys, Grapnels, Mushrooms--and Men.]
The testing arrangements had been perfected by Mr. Willoughby Smith in
such a way that insulation readings could be continuously observed,
even while measuring the copper resistance, or while exchanging signals
with Valentia. Thus there was no longer any danger of a fault being paid
overboard without instant detection. On this occasion also condensers
were applied to the receiving-end of the cable, having the effect of
very materially increasing--indeed, sometimes almost doubling--the
working speed.
On June 30, 1866, the Great Eastern, steaming from the Thames--followed
by the Medway and Albany--arrived at Valentia, where H.M.S. Terrible and
Racoon were found, under orders to accompany the expedition. The Medway
had on board forty-five miles of deep-sea cable in addition to the
American shore end.
The principal members of the staff acting on behalf of the contractors
in this expedition were the same as in that of the previous year. Mr.
Canning was again in charge, with Mr. Clifford and Mr. Temple as his
chief assistants. In the electrical department, however, the Telegraph
Construction Company had since secured the services of Mr. Willoughby
Smith as their chief electrician, while he still acted in that capacity
at the Wharf Road Gutta-Percha Works. Mr. Smith, therefore, accompanied
the expedition as chief electrician to the contractors. Captain James
Anderson and Staff-Commander H. A. Moriarty, R.N., were once more to be
seen on board the great ship, the former as her captain, and the latter
as navigating officer. Professor Thomson was aboard as consulting
electrical adviser to the Atlantic Telegraph Company, while Mr. C. F.
Varley was ashore at Valentia as their electrician. Sir Charles Bright
(then M.P. for Greenwich) was at this period serving on various
committees of the House of Commons;[63] but his partner, Mr. Latimer
Clark, took up quarters at Valentia to personally represent the firm as
consulting engineers to the Anglo-American Telegraph Company. Mr. J. C.
Laws and Mr. Richard Collett[64] being respectively aboard and ashore at
the Newfoundland end in the same interests. Mr. Glass, the managing
director of the Telegraph Construction Company, was ashore at Valentia
for the purpose of giving any instructions to his (the contractor's)
staff on board, while Mr. Gooch and Mr. Field were aboard the Great
Eastern as onlookers and watchers of their individual interests.
_Cable-Laying again._--On July 7th the William Cory--commonly known as
the Dirty Billy--landed the shore end in Foilhommerum Bay, and afterward
laid twenty-seven miles of the intermediate cable. On the 13th, the
Great Eastern took the end on board, and having spliced on to her cable
on board, started paying out. The track followed was parallel to that
taken the year before, but about twenty-seven miles farther north. There
were two instances of fouls in the tank, due to broken wires catching
neighboring turns and flakes, and thus drawing up a whole bundle of
cable in an apparently inextricable mass of kinks and twists quite close
to the brake-drum. In each case the ship was promptly got to a
standstill and all hands set to unraveling the tangle. With a certain
amount of luck, coupled with much care, neither accident ended fatally;
and, after straightening out the wire as far as possible, paying out was
resumed.
[Illustration: FIG. 39.--"Foul in Tank" while Paying out.]
_Successful Completion._--Fourteen days after starting the Great Eastern
arrived off Heart's Content,[65] Trinity Bay, where the Medway joined on
and landed the shore end partly by boats, thus bringing to a successful
conclusion this part of the expedition. The total length of cable laid
was 1,852 nautical miles; average depth, 1,400 fathoms. Rejoicings then
took place during the coaling of the Great Eastern--to provide for
which as many as six coal-laden steamers had left Cardiff some weeks
before. The rejoicings were somewhat damped by the fact that the cable
between Newfoundland and Cape Breton (Nova Scotia) still remained
interrupted, and that consequently the entire telegraphic system was not
even now completed. However, in the course of a few days this line was
repaired, and New York and the east of the United States and Canada were
once more put into telegraphic communication with Europe.
The telegraphic fleet put to sea again on August 9th.
CHAPTER XVI
RECOVERY AND COMPLETION OF THE 1865 CABLE
Prospects and Plans--Setting to Work--Repeated Failures--Ultimate
Triumph--Electricians
Ashore--"Spot-watching"--"Putting-through"--Pioneering--Working the
Lines.
_Prospects and Plans._--It now remained to find the end of the cable
lost on August 2, 1865, situated about 604 miles from Newfoundland, to
pick it up, splice on to the cable remaining on board, and finish the
work so unfortunately interrupted the year before. The difficulties to
be overcome can be readily imagined, the cable lying 2,000 fathoms
without mark of any kind to indicate its position. The buoys put down
after the accident had long since disappeared, either their moorings
having dragged during various gales of wind, or the wire ropes which
held them having chafed through, owing to incessant rise and fall at the
bottom. The position of the lost end had to be determined by
astronomical observations. These necessitate clear weather, and can then
only give approximate results on account of the variable ocean currents,
which sometimes flow at the rate of three knots. Moreover, for grappling
and raising the cable to the bows, the sea must be tolerably smooth; and
in that part where the work lay a succession of fine days is rare, even
in the month of August. However, they still had on board Captain
Moriarty, one of the ablest navigators in the world. Added to this, the
greater portion of the cable in deep water had been paid out with about
15 per cent slack.
The chiefs of the expedition, fully confident of success, hastened their
preparations, and on August 9, 1866, the Great Eastern again put to sea,
accompanied by S.S. Medway. On the 12th the vessels arrived on the scene
of action, and joined company with H.M.S. Terrible and S.S. Albany,
these vessels having left Heart's Content Bay a week in advance to buoy
the line of the 1865 cable and commence grappling.
The plan decided on was to drag for the cable near the end with all
three ships at once. The cable when raised to a certain height, was to
be cut by the Medway stationed to the westward of the Great Eastern, so
as to enable the latter vessel to lift the Valentia end on board. This
was, of course, before the days of cutting and holding grapnels as we
now have them, which render it possible for a single ship to effect
repairs--even where it is out of the question to recover the cable in
one bight.
[Illustration: FIG. 40.--S.S. Great Eastern Completing the Second
Atlantic Cable.]
_Setting to Work: Repeated Failures._--When the Great Eastern arrived on
the grappling ground, the Albany (with Mr. Temple in engineering charge)
had already hooked and buoyed the cable, but the buoy-chain having been
carried away, they not only lost the cable, but 2,000 fathoms of wire
rope besides. On August 13th the Great Eastern made her first drag,
about fifteen miles from the end, and, after several vain attempts, the
cable was finally hooked and lifted about 1,300 fathoms. During the
operation of buoying the grappling rope, a mistake occurred which
resulted in the rope slipping overboard and going to the bottom.
The Great Eastern now proceeded six miles to the eastward, and commenced
a new drag, for raking the ocean bed with 2,400 fathoms of wire rope.
About eleven o'clock at night the grapnel came to the surface with the
cable caught on two of the prongs. Boats were quickly in position
alongside the grapnel. Shortly afterward they were endeavoring to secure
the cable to the strong wire rope, by means of a nipper, when the
grapnel canted, allowing the line to slip away from the prongs--like a
great eel--and disappear into the sea. On the 19th the cable was once
more hooked, and raised about a mile from the bottom, but the sea was
too rough for buoying it. During the following week all three vessels
dragged for the cable at different points, according to the plan
previously arranged, but the weather was unfavorable, and the cable was
not hooked--or, if hooked, had managed to slip away from the grapnels.
The ship's company about this time became discouraged--in fact, more and
more convinced of the futility of their efforts.
On the 27th the Albany signaled that they had got the cable on board
with a strain of only three tons, and had buoyed the end, but it was
soon discovered that her buoy was thirteen miles from the track of the
cable, and that she had recovered a length of three miles which had been
purposely paid overboard a few days before. Shifting ground to the
eastward about fifteen miles, the vessels were now working in a depth of
2,500 fathoms. As the store of grappling rope was diminishing day by
day, and the fine season rapidly coming to an end, it was decided to
proceed at once eighty miles farther east, where the depth was not
expected to exceed 1,900 fathoms, and there try a last chance.
_Ultimate Triumph._--After the above repeated failures, the cable was
hooked on August 31st by the Great Eastern (when the grapnel had been
lowered for the thirtieth time), and picking up commenced in very calm
weather. The monster vessel did her work admirably. To quote the words
of an eye-witness: "So delicately did she answer her helm, and coil in
the film of thread-like cable, that she put one in mind of an elephant
taking up a straw in its proboscis." When the bight of cable was about
900 fathoms from the surface, the grappling-rope was buoyed. The big
ship then proceeded to grapple three miles west of the buoy (Fig. 41),
and the Medway (with Mr. London on board) another two miles or so west
of her again. The cable was soon once more hooked by both ships, and
when the Medway had raised her bight to within 300 fathoms of the
surface she was ordered to break it. The Great Eastern having stopped
picking up when the bight was 800 fathoms from the surface, proceeded to
resume the operation as soon as the intentional rupture of the cable had
eased the strain, which, with a loose end of about two nautical miles,
at once fell from 10 or 11 tons to 5 tons. Slowly, but surely, and amid
breathless silence, the long-lost cable made its appearance at last (see
opposite), for the third time above water, a little before one o'clock
(early morn) of September 2d.[66]
Two hours afterward the precious end was on board, and signals were
immediately exchanged with Valentia. This was at once led into the
testing-room, where Mr. Willoughby Smith, in the presence of all the
leaders on board, applied the tests which were to determine the
important question regarding the condition of the cable, and whether it
was entirely continuous to each end. In a few minutes all suspense was
relieved, the tests showed the cable to be healthy and complete, and
immediately afterward (in response to the ship's call) the answering
signals were received from the Valentia end, which were received with
loud cheers that echoed and reechoed throughout the great ship.
_Electricians Ashore: "Spot-watching."_--Let us now look at those
patiently watching day after day, night after night, in the wooden
telegraph cabin on shore, the experience of whom may be taken as a fair
sample of that of the electrician ashore during repairing operations in
the present day.
[Illustration: FIG. 41.--Diagram Illustrative of the Final Tactics
Adopted for Picking up the 1865 Cable.

]
Such a length of time had elapsed since the expedition left Newfoundland
that the staff at Foilhommerum, under the superintendence of Mr. James
Graves, felt they were almost hoping against hope. Suddenly, on a Sunday
morning at a quarter to six, while the tiny ray of light from the
reflecting instrument was being watched, the operator observed it moving
to and fro upon the scale. A few minutes later the unsteady flickering
was changed to coherency. The long-speechless cable began to talk, and
the welcome assurance arrived, "Ship to shore; I have much pleasure in
speaking to you through the 1865 cable. Just going to make splice." Glad
tidings were also sent from the ship via Valentia to London, and, by
means of the 1866 cable, to Newfoundland and New York. Thus it happened
that those being tossed about in a stormy sea held conversation with
Europe and America at one and the same time.[67]
"_Putting Through._"--The recovered end was spliced on without delay to
the cable on board, and the same morning at seven o'clock the Great
Eastern started paying out about 680 nautical miles of cable toward
Newfoundland. On September 8th, when only thirteen miles from the Bay of
Heart's Content, just after receiving a summary of the news in The Times
of that morning, the tests showed a fault in the cable. The mischief was
soon found to be on board the ship, and caused by the end of a broken
wire, which, bending at right angles under the weight of the men
employed in the tanks, had been forced into the core. This occurrence
explained the probable cause of the faults (of same character) which had
shown themselves during paying out the year before, tending to remove
all suspicion of malicious intent. The faulty portion having been cut
out, and the splice made without delay, paying out again proceeded,
finishing the same day at eleven o'clock in the forenoon. The Medway
immediately set to work laying the shore end, and that evening a second
line of communication across the Atlantic was completed. The total
length of this cable, commenced in 1865, was 1,896 miles; average depth,
1,900 fathoms.
[Illustration: FIG. 42.--S.S. Great Eastern with 1865 Cable at Bows;
Depth, 2 Miles.]
_Pioneering._--The main feature and accomplishment in connection with
the second and third Atlantic cables of 1865 and 1866 was, without
doubt, the recovery of the former in deeper water than had ever been
before effected, and in the open ocean; just as in the first 1858 line
it was the demonstration of the fact that a cable could be successfully
laid in such a depth and worked through electrically. In the interval
between the two undertakings cable repairs had certainly been carried
out in the Mediterranean in 1,400 fathoms. Moreover, the recovery and
repair of a cable from the depths of the open ocean are now matters of
ordinary every-day occurrence, forming part and parcel of cable
operations generally. These facts should not, however, in any way
detract from the greatness of the achievement at that time in so vast
and boisterous an ocean.
_Working the Two Lines._--Professor Thomson's reflecting-apparatus for
testing and signaling had been considerably improved since the first
cable. In illustration of the degree of sensibility and perfection
attained at this period in the appliances for working the line, the
following experiment is of striking interest: Mr. Latimer Clark, who
went to Valentia to test the cable for the "Atlantic" Company, had the
conductor of the two lines joined together at the Newfoundland end, thus
forming an unbroken length of 3,700 miles in circuit. He then placed
some pure sulfuric acid in a silver thimble,[68] with a fragment of zinc
weighing a grain or two. By this primitive agency he succeeded in
conveying signals twice through the breadth of the Atlantic Ocean in
little more than a second of time after making contact. The deflections
were not of a dubious character, but full and strong, the spot of light
traversing freely over a space of twelve inches or more, from which it
was manifest that an even smaller battery would suffice to produce
somewhat similar effects. Again, in testing these cables it was found
that if either was disconnected from the earth and charged with
electricity, it required more than an hour for half of the charge to
escape through the insulating material to the earth. This speaks well
for the electrical components assigned to the two lines, and for the
arrangements adopted in working them. It also shows the benefit derived
from seven years' extra experience in manufacture, backed up by the
previously mentioned exhaustive Government inquiry thereon.
Notwithstanding the dimensions of the core, these cables were worked
slowly at first, and at a rate of about eight words per minute. This,
however, soon improved as the staff became more accustomed to the
apparatus, and steadily increased up to fifteen--and even
seventeen--words per minute on each line, with the application of
condensers.
Unfortunately both these cables broke down a few months later, and one
of them again during the following year. The faults were localized with
great accuracy from Heart's Content by Mr. F. Lambert on behalf of
Messrs. Bright & Clark, engineers to the "Anglo-American" Company.
Unlike the 1858 line, however, these last cables had not been killed
electrically, and, being worthy of repairs, they were maintained for a
considerable time.
CHAPTER XVII
JUBILATIONS
Banquets--Speeches--Honors
On the return of the 1866 Expedition a banquet was given to the
cable-layers by the Liverpool Chamber of Commerce, as soon as the Great
Eastern was safely moored in the Mersey.
The following from The Times will be of some interest here:
The chair was occupied by the Rt. Hon. Sir Stafford Northcote,
Bart.,[69] President of the Board of Trade. The following were
among the invited guests: the Rt. Hon. Lord Stanley, M.P.,
Secretary of State for Foreign Affairs; the Rt. Hon. Lord
Carnarvon; the Rt. Rev. the Lord Bishop of Chester; the Rt. Hon. W.
E. Gladstone, M.P.; Sir Charles Bright, M.P., original projector of
the Atlantic cable, and Engineer to the Anglo-American Telegraph
Company; Prof. W. Thomson, electrical adviser to the Atlantic
Telegraph Company; Mr. Latimer Clark, coengineer with Sir Charles
Bright; Mr. R. A. Glass, managing director to the Telegraph
Construction Company (contractors); Mr. Samuel Canning, engineer to
the contractors; Mr. Henry Clifford, assistant engineer to the
contractors; Mr. Willoughby Smith, electrician to the contractors;
Captain James Anderson, commander of the Great Eastern; Mr. William
Barber, chairman of the Great Ship Company; Mr. John Chatterton,
manager of the Gutta-Percha Works; Mr. E. B. Bright, Magnetic
Telegraph Company; Mr. T. B. Horsfall, M.P.; and Mr. John Laird,
M.P.
After proposing toasts to Her Majesty the Queen, to the President
of the United States, and to the Prince of Wales, the chairman (Sir
S. Northcote) again rose amid applause, and said it was a maxim of
a great Roman poet that a great work should be begun by plunging
into the middle of the subject. He would therefore do so by
proposing a toast to the projectors of the Atlantic Telegraph--Sir
Charles Bright and Mr. Cyrus Field, Mr. J. W. Brett having since
unfortunately died. When they came in after years to relate the
history of this cable, they would find many who had contributed to
it, but it would be as impossible to say who were the originators
of the great invention as it was to say who were the first
inventors of steam. He begged to couple with the toast the name of
Sir Charles Bright, as, perhaps, the foremost representative from
all points of view up to the present time (applause). The greatest
honor is due to the indomitable perseverance and energy of Sir
Charles Bright that the original cable was successfully laid,
though, through no fault of his, it had but a short useful
existence (great cheering).
Sir Charles Bright, M.P., after acknowledging the compliment paid
to the "original projectors" and to himself personally, said that
the idea of laying a cable across the Atlantic was the natural
outcome of the success which was attained in carrying short lines
under the English and Irish Channels, and was a common subject of
discussion among those concerned in telegraph extension prior to
the formation of the Atlantic Telegraph Company.
About ten years ago the science had sufficiently advanced to permit
of the notion assuming a practical form. Soundings taken in the
Atlantic between Ireland and Newfoundland proved that the bottom
was soft, and that no serious currents or abrading agencies
existed, for the minute and fragile shells brought up by the
sounding-line were perfect and uninjured.
There only remained the proof that electricity could be employed
through so vast a length of conductor. Upon this point and the best
mode of working such a line, he had been experimenting for several
years. He had carried on a series of investigations which resulted
in establishing the fact that messages could be practically passed
through an unbroken circuit of more than 2,000 miles of insulated
wire, a notion derided at that time by many distinguished
authorities. Mr. Wildman Whitehouse, who subsequently became
electrician to the company, had been likewise engaged. On comparing
notes later, it was discovered that we had arrived at similar
results, though holding somewhat different views, for his (Sir C.
Bright's) calculations, using other instruments, led him to believe
that a conductor nearly four times the size of that adopted would
be desirable with a slightly thicker insulator. It was this type
which the new cables just laid had been furnished with.
In 1856, Mr. Cyrus Field--to whom the world was as much indebted
for the establishment of the line as to any man--came over to
England upon the completion of the telegraph between Nova Scotia
and Newfoundland. He then joined with the late Mr. Brett and
himself (Sir C. Bright) with the view of extending this system to
Europe, and they mutually agreed, as also did Mr. Whitehouse later,
to carry out the undertaking. A meeting was first held in
Liverpool, and in the course of a few days their friends had
subscribed the necessary capital. So that in greeting those who had
just returned from the last expedition--Mr. Canning, Mr. Clifford,
Captain Anderson, and other guests of the evening--Liverpool was
fitly welcoming those who had accomplished the crowning success of
an enterprise to which at the outset she had so largely contributed
(applause).
The circumstances connected with the first cable would be in the
recollection of every one, and, although the loss was considerable,
the experience gained was of no small moment. A few months after
the old line had ceased to work, their chairman (Sir S. Northcote)
consulted him on behalf of the Government as to the best form of
cable for connecting us telegraphically with Gibraltar, and he
(Sir C. Bright) did not hesitate to recommend the same type of
conductor and insulator which he had himself before suggested for
the Atlantic line--a higher speed being desirable. This class of
conductor in the newly laid Atlantic cable appeared likely to give
every satisfaction, he was happy to say, and the mechanical
construction of the cable, also the same as that he had previously
specified for the Gibraltar line, appeared to have admirably met
some of the difficulties experienced in cable operations.
The credit attached to these second and third Atlantic cables must
mainly rest with the Telegraph Construction Company (formerly
Messrs. Glass, Elliot & Co.) and their staff, inasmuch as in this
case the responsibility rested with them throughout. The
directors--including Mr. Glass, Mr Elliot, Mr. Gooch, Mr. Pender,
Mr. Barclay, and Mr. Brassey--deserved the reward which they and
the shareholders would no doubt reap. To Mr. Glass, upon whom the
principal responsibility of the manufacture devolved, the greatest
praise was due for his indomitable perseverance in the enterprise.
Then the art of insulating the conducting-wire had been so
wonderfully improved by Mr. Chatterton and Mr. Willoughby Smith,
that, nowadays, a very feeble electrical current was sufficient to
work the longest circuits, an enormous advance on the state of
affairs nine years previously. Again, they must not forget how much
of the success now attained was due to Professor Thomson and his
delicate signaling-apparatus, the advantages of which have since
1858 been more firmly established. Mr. Varley had also done most
useful work since becoming electrician to the "Atlantic" Company.
Moreover, he (Sir C. Bright) hoped the active personal services of
his partner, Mr. Latimer Clark, would not be forgotten.
It was satisfactory to find that the cables were already being
worked at a very large profit. This system would doubtless be
quadrupled within a short period, when the land-lines on the
American side were improved (hear, hear, and applause). With this
commercial success--combined with the improvements introduced into
submarine cables, and the power of picking up and repairing them
from vast depths--there was a future for submarine telegraphy to
which scarcely any bounds could be imagined. A certain amount had
already been done, but China and Japan, Australia and New Zealand,
South America and the West India Islands, must all be placed within
speaking-distance of England. When this last has been accomplished,
but not till then, telegraphic engineers might take a short rest
from their labors and ask with some little pride:
Quoe regio in terris nostri non plena laboris? (loud applause).
Then followed speeches from Lord Stanley, the American Consul (on behalf
of Mr. Cyrus Field), and others.
Honors were subsequently bestowed on some of the various gentlemen most
immediately concerned in these--at last--wholly successful undertakings
of 1865 and 1866, which left their results behind in complete and
lasting form.
CHAPTER XVIII
SUBSEQUENT ATLANTIC LINES
As a natural sequence other Atlantic cables followed in course of time.
Thus in 1869 France was put into direct telegraphic communication with
America by means of a cable from Brest to the island of St. Pierre, and
another from St. Pierre to Sydney, U.S.A.[70] The former length was
manufactured by the Telegraph Construction and Maintenance Company, and
the latter by Mr. W. T. Henley. The Telegraph Construction Company were
the contractors for laying the whole cable on behalf of the French
Atlantic Cable Company (Société du Câble Trans-Atlantique Français).[71]
This work was successfully accomplished from the Great Eastern (Captain
Robert Halpin) by the same staff as had laid the 1866 cable. Owing to
the route, this line was materially longer than the previous Atlantic
cables, its length (from Brest to St. Pierre) being as much as 2,685
nautical miles. The working-speed attained on the French Atlantic cable
was ten and a half words per minute. The conductor of the Brest-St.
Pierre section was composed of seven copper wires stranded together,
weighing 400 pounds per nautical mile, covered with a gutta-percha
insulator of the same weight. The core of the St. Pierre-Sydney section
was made up as follows: Copper = 107 pounds per nautical mile;
gutta-percha = 150 pounds per nautical mile. Like the previous lines,
this cable has been "down," electrically speaking, for some years. It
proved a very costly one in repairs, one expedition alone having run
into as much as £95,000.
In 1873 the Direct United States Cable Company was formed, being the
first competitor--from this country--with the "Anglo-American"
Company.[72] Messrs. Siemens Brothers, who had taken an active part in
the promotion of the scheme, were the contractors, both for manufacture
and for submersion. It was, indeed, the first really important length
with which this firm had been concerned as manufacturers. The laying was
attended with complete success, and the line opened to the public in
1875. Later on, in 1877, the "Direct United States" Company was
reconstructed, their system entering into the "pool" or "joint purse."
The latter was established shortly after the 1869 Atlantic cable had
been laid, constituting one great financial combination.
In 1879 another French company was formed to establish independent
communication between France and the rest of the European Continent on
the one hand, and the United States of America on the other. The, to
English ears and lips, somewhat cumbersome title of this concern was La
Compagnie Française du Télégraphe de Paris à New York, but it soon
became styled in England the "P. Q. Company," after M. Pouyer-Quertier,
its presiding genius. The cable was made and laid in the same year by
Messrs. Siemens Brothers, though the scheme had taken three years to
reach contract point. The "P. Q." Company in 1894 amalgamated with La
Société Française des Télégraphes Sous-marins, under the title of La
Compagnie Française des Câbles Télégraphiques.
In 1881 an American company was formed, under the guidance of the late
Mr. Jay Gould, entitled The American Telegraph and Cable Company, with a
view to partaking in the profits of transatlantic telegraphy by
establishing another line of communication between the United States and
Great Britain, and thence to the rest of Europe. This cable was also
constructed and laid (in the course of that year) by Messrs. Siemens
Brothers, who were part promoters of the enterprise, as well as another
cable for the same system in the following year, 1882. This company's
cables are leased by the Western Union Telegraph Company, which was
practically Jay Gould's property, and remained so up to close on the
time of his death, a few years ago. In 1883 the above system entered the
"Pool"--the happy destination for which, maybe, it was originally
launched into existence.
A fresh competitor arrived in 1884 in the person of the Commercial Cable
Company. Two cables were laid across the Atlantic for this company in
the same year, its promoters wisely foreseeing that, in view of the
continual chance of a breakdown, this was the only way in which they
could safely attempt to compete with their more firmly established
rivals. The "Commercial" Company was mainly promoted by two American
millionaires, Mr. J. W. Mackay, the celebrated New York financier, and
Mr. Gordon Bennett, the proprietor of the New York Herald; with them
were associated Messrs. Siemens Brothers, who afterward became the
contractors for the enterprise. These cables, like the Jay Gould lines,
stretch from the extreme southwest point of Ireland (which is connected
by special cable with England) to Nova Scotia, and thence to the United
States, one of them direct to New York. The system is directly connected
with that of the Canadian Pacific Railroad Company, thus affording ready
communication with the Dominion.
Neither the "Commercial" Company's system nor that of the Compagnie
Française des Câbles Télégraphiques is at present in the "Atlantic
Pool."
In 1894 yet two more additions were made to the list of Atlantic
cables--one on behalf of the Commercial Cable Company, and the other for
the "Anglo-American" Company. The new "Commercial" line was constructed
and laid by Messrs. Siemens Brothers, and the "Anglo" cable by the
Telegraph Construction Company. Fig. 43 shows the type adopted for the
deepest water of the latter, and Fig. 44 that for the shore ends. Here
the wires, besides being of a very large gauge, are applied with an
extremely short lay (hence the elliptic appearance, though circular in
reality), in order to increase the weight of iron, and thereby avoid
shifting and abrasion. This type is now in constant use where rocks,
ice-floes, strong currents, or rough weather are experienced. Special
arrangements were made in the design of both these cables to meet the
requirements of increased speed. Since the successful application to
submarine cables of various modifications of Wheatstone's automatic
transmitter, the limit to the speed attainable only depends, practically
speaking, upon the type of cable employed. On these principles the core
of the new "Commercial" cable was composed of a copper conductor
weighing 500 pounds per nautical mile, covered with a gutta-percha
insulating-sheath weighing 320 pounds per nautical mile, while the new
"Anglo" has a core with conductor weighing 650 pounds per nautical mile,
and gutta-percha insulator 400 pounds per nautical mile, involving a
completed cable (main type) nearly double the weight of previous
corresponding lines.
[Illustration: FIG. 43.--Anglo-American Atlantic Cable (1894): deep-sea
type.]
[Illustration: FIG. 44.--Shore-end of the 1894 "Anglo" Cable. Reduced
size.]
The actual speed obtained by automatic transmission with the latter
cable is as high as forty-seven (or even up to fifty) five-letter words
per minute. On the previous, lighter, Atlantic cores twenty-five to
twenty-eight words per minute was the usual maximum speed attainable;
the former, say, by average transmission and average receiving, and the
latter by automatic transmission--other circumstances corresponding.
Practically all submarine cables between important points--and certainly
all those across the Atlantic--are now "duplexed"--a system of
electrical working (instituted by Messrs. Muirhead in 1875) which
enables messages to be sent in both directions at the same time. The
result of this is nowadays to practically double the carrying capacity
and earning power of the line, the effective speed in either direction
remaining virtually the same as in "simplex" working, provided the cable
is in good condition.[73] The armor of this cable (Fig. 43) is also a
good example of present-day practise, each wire (usually covered with
compounded tape) butting against the next; this is found to be the most
durable form for a deep-sea cable.
In 1898 another French Atlantic line of a similar type to the above was
laid. This involved the longest Atlantic cable-section in existence,
i.e., 3,174 nautical miles, from Brest to Cape Cod, and was the first
Atlantic line made and laid by Frenchmen, with the active assistance, as
regards laying, of the Silvertown Company.
Recently, too, a German Atlantic cable has been laid by the Telegraph
Construction Company from Emden to the Azores, and hence to New York.
* * * * *
The various proprietary companies here named have had duplicating lines
laid for them from time to time, but these it is not necessary to
further allude to.
Neither has it been thought necessary to give particulars regarding the
methods of construction, laying, testing or working of any of these
later lines following on the pioneer undertakings, except where special
novelties were introduced. For similar reasons--and seeing that the
responsibility of these later lines rested with contractors--the names
of their permanent staff acting for them have not been introduced.
CHAPTER XIX
ATLANTIC CABLE SYSTEMS OF TO-DAY
Connecting Links--Tariff--Revenue
As a part of the union between the old world and the new, there are
altogether fifteen cables now working across the North Atlantic Ocean
(see Fig. 45), such as are usually termed "Atlantic cables." Some of the
Atlantic companies have special cables of their own from the landing
place on the coast of Ireland to points on the Continental coasts. The
figure on page 221 suggests one of the difficulties any wireless system
would have to contend with in attempting at transatlantic telegraphy on
a commercial basis.[74] Some of these cables at each end of the
corresponding main section contain more than one insulated conductor.
_Tariff._--In the early pioneer days of ocean telegraphy the Atlantic
Telegraph Company started with a minimum tariff of £20 for twenty words,
and £1 for each additional word. This was first reduced to £10 for
twenty words, and was further altered later on to £5 for ten words.
After this it stood for a long time at a minimum of 30s. for ten words
of five letters each. Subsequently, in 1867, the Anglo-American Company
tried a word-rate of £1 for the 1865 and 1866 Atlantic cables; but it
was not until 1872 that Mr. Henry Weaver, their able manager, first
instituted a regular word-rate system (without any minimum) of 4s. per
word. At the present time (1903), thanks to competition, to technical
improvements in the plant, and increased traffic--bringing in its train
those economies in the working which are always possible in a larger
scale of operation--the rate stands at 1s. a word with all the Atlantic
companies. Some day we may, perhaps, see a sixpenny transatlantic tariff
in permanent force.
[Illustration: FIG. 45.--Atlantic Cable Systems, 1903.]
_Revenue._--The fifteen Atlantic cables now in use represent a total
capital of well over £20,000,000 sterling. A knowledge of the profits
derived from each system is not readily arrived at; but from a
comparison of the traffic receipts or "money returns" of the oldest
existing Atlantic company at different periods, we are bound to conclude
that the "takings" are, roughly speaking, very much the same now as they
were twenty-five years ago. This is explainable by the fact that,
although the number of messages now passing is much greater, the
reduction of the rate (with the ever-increasing competition of rival
lines) just about cancels the advantage, so far as receipts are
concerned. Roughly speaking, however, the annual gross traffic on
transatlantic telegraphy stands at about £1,200,000, divided among two
English companies, two American, one French, and one German company.
Both the two latter are materially subsidized by their respective
Governments, who now foresee the desirability of being independent of
cables under English control.

[5] It was gravely suggested by a prominent naval officer to thread
the line through old cannonades lying idle, at Portsmouth harbor.
This notion was not taken up; but a light chain twined round the
insulated conductor throughout its length would certainly have served
the purpose better than the leaden weights, inasmuch as it would have
protected the line from chafing, besides being less liable to damage
the core.
[6] Some critics had actually supposed that the method of signaling
was that of _pulling_ the wire after the manner of mechanical
house-bells; and were at pains to point out that the bottom of the
channel was too rough for that.
[7] For further particulars, see the Life Story of Sir Charles Tilston
Bright. (London: Archibald Constable & Co., 1898.)
[8] It will be readily understood that without this weight, the line
would not for certain descend to the bottom--and certainly not in
a straight line--in any considerable depths. On the other hand, it
would be impossible to recover an effective weight without great risk
of breaking the line. For this reason the weight is abandoned, and a
considerable number may be found at the bottom of the sea in every
quarter of the globe.
[9] These live near the surface of the ocean in myriads upon myriads,
incessantly sinking to the bottom as their short life is ended. Thus,
in the course of ages, there grows constantly upward a formation
similar to the chalk cliffs of England, which contain the identical
shells, deposited when this country was submerged far below sea-level
thousands of years ago.
[10] In the present day, however, soundings are taken at intervals
of about ten miles along the proposed route, and even then submarine
hills and valleys are frequently encountered. This is effected by
means of the Thomson steam sounding-apparatus, the great feature of
which is a fine steel wire (the same as that in the treble notes of a
piano) in place of a hempen line of enormous bulk. Nowadays, taking a
sounding in the Atlantic occupies well under an hour of time, where by
the old method it took at least six hours.
[11] The full particulars of the agreement with the English Government
were embodied in a letter from the Treasury (see Life Story of Sir
Charles Bright) and form instructive reading even at the present time.

[18] An Atlantic cable of the present day runs into about half a
million sterling. Gutta-percha was, in those days, less scarce; on
the other hand, its manufacture was more of a novelty, and there was
comparatively little competition in cable-making.
[19] Professor Morse (who held a sort of watching brief for the United
States Government) also took passage, but had to retire to his berth
as soon as the elements asserted themselves, and was scarcely visible
again till all was over.
[20] The sheaves had several grooves which the cable fitted into in
its passage. Though possessing some merits, this plan was never again
adopted, owing partly to the above risk.
[21] This was owing to the two halves of the cable being made at
different factories, without any communication passing between them on
the subject.
[22] This apparatus first gained its name from the nature of the part
it plays in machinery, being similar to that of a human jockey.
[23] So called on account of the form of grooving adopted for taking

[24] Submarine Telegraphs.
[25] It is partly for this reason that so full an account is given
here.
[26] In those days all such instruments were spoken of as
galvanometers, no matter for what purpose they were employed.
Moreover, this instrument was also used sometimes for testing. That
which goes by the name of the marine galvanometer in the present day
was not invented by Lord Kelvin till some years later.
[27] This splice-frame was an ingenious arrangement for neutralizing
the untwisting tendency of two opposite lays when spliced together,
but is never required in present-day practise.
[28] This, of course, did not in any way come as a surprise, for the
length of cable employed for these experiments had long since been
condemned as imperfect.
[29] And so it is sometimes with telegraph-ships--as regards the dead
weight of cable--even in the present day, when compared with the risks
run by ordinary seagoing vessels.
[30] When these part to any extent a ship is always considered in a
dangerous condition.
[31] By subsequent tests it was clear that at any rate the cable
remaining on board was perfect. But after com paring notes with the
Niagara, a strong belief was held that the cable probably parted at
the bottom.
[32] This was from the last turn in the coil, and subsequently it was
discovered that owing to the disturbance in the flooring of the tank
during the storm, the cable had been damaged here.
[33] Life-Story of Sir Charles Bright.
[34] Though bearing this somewhat cumbersome and elaborate title, this
instrument was practically nothing more nor less than an ordinary
"detector," its capacity for actually measuring the electric current
being of an extremely limited character.
[35] This was some of the cable damaged during the storm, like that
which had been broken at the end of the previous attempt. The bottom
of the hold here was found afterward to be in a very disordered state.
[36] Later on it was made clear that this mysterious temporary want of
continuity, accompanied by an apparent variation in the insulation,
was due to a defect in the more or less inconstant sand-battery used
aboard the latter vessel.
[37] It subsequently transpired that the trouble had been due to a
fault in the Niagara's ward-room coil. As soon as the electricians
discovered this, and had it cut out, all went smoothly again.
[38] The amount of slack paid out had already been almost ruinous.
Luckily its continuance was not necessary, or it would have been
impossible to reach Ireland with the cable on board.

[48] In his work on the Electric Telegraph, the late Mr. Robert Sabine
said: "At the date of the first Atlantic cable, the engineering
department was far ahead of the electrical. The cable was successfully
laid--mechanically good, but electrically bad." Its electrical failure
was, of course, bound to spell commercial failure, no matter how great
its success as an engineering feat.
[49] In his presidential address to the Institution of Electrical
Engineers in 1889, Lord Kelvin (the Professor Thomson referred to in
these pages) said: "The first Atlantic cable gave me the happiness
and privilege of meeting and working with the late Sir Charles
Bright. He was the engineer of this great undertaking--full of
vigor, full of enthusiasm. We were shipmates on the Agamemnon on the
ever-memorable expedition of 1858, during which we were out of sight
of land for thirty-three days. To Sir C. Bright's vigor, earnestness,
and enthusiasm was due the successful laying of the cable. We must
always feel deeply indebted to our late colleague as a pioneer in that
great work, when other engineers would not look at it, and thought it
absolutely impracticable."

[57] Mr. Field compassed land and sea incessantly for the purpose
of agitating the subject. He is said to have crossed the Atlantic
altogether sixty-four times--suffering from sea sickness on each
occasion--in connection with this great enterprise in which he formed
so prominent a figure.
[58] Afterward Sir John Pender, G.C.M.G., M.P.
[59] The increased breaking strain here afforded over that of the
first Atlantic line was partly due to the great improvement made in
the manufacture of iron wire during the interval.
[60] Experience has since taught us, however, that such a type lacks
durability, owing to the rapid decay of the hemp between the iron
wires and the sea.
[61] The Great Eastern, in point of size, was only a little before her
time. In the present day, with improved engines, she could be usefully
and profitably employed, had she not been broken up.

[64] At a later period--after both the 1865 and 1866 cables were
in working order--Mr. Collett sent a message from Newfoundland to
Valentia with a battery composed of a copper percussion-cap and a
small strip of zinc, which were excited by a drop of acidulated
water--the bulk of a tear only.
[65] This is situated on the opposite side of Trinity Bay to Bull
Arm, where the 1858 cable had been landed, and not so far up. It was
supposed to be even more protected than Bull Arm, from which it is
some eighteen miles distant.
[66] Submarine Telegraphs.
[67] This is, of course, nowadays quite an ordinary occurrence, and
by means of wireless telegraphy likely to become still more so. Then,
however, it was a complete novelty.
[68] Mr. Clark borrowed the thimble--which was a very small one--from
Miss Fitzgerald, the daughter of the Knight of Kerry, living at
Valentia.
[69] Afterward the first Earl of Iddesleigh, G.C.B.
[70] This enterprise, although mainly on behalf of France and the rest
of the European continent, was principally advanced by financiers
in England; the working of the cable was also chiefly under British
direction and management.
[71] Afterward, in 1873, merged with its cable into the Anglo-American
Telegraph Company and its system.
[72] This company had just had two fresh cables laid for them (1873
and 1874) by the Telegraph Construction Company with some of their
usual staff. The laying of the 1874 Atlantic was the last piece of
telegraph work performed by the Great Eastern. She has since been
broken up, after being employed, among other things, as a sort of
variety show. New cables were first rendered necessary--according
to the joint-purse agreement previously referred to--by the final
breakdown, after several repairs, of the 1866 cable in 1872. Later
on (in 1877) the 1865 also succumbed, and another "Anglo" cable was
laid by the same contractors in 1880. The Telegraph Construction and
Maintenance Company laid this 1880 cable without any hitch or stoppage
within the surprisingly short space of twelve days, the record up to
date in Atlantic cable-laying.
[73] Thus the Atlantic cable of to-day may be credited with an
"output" of 100 words a minute as compared with a single word in the
same period, such as was at first obtained in the pioneer days of one
cable worked by one company.
[74] Wireless telegraphy is at present a comparatively slow working
affair; and if it is to successfully compete with our Atlantic
cables, this means a great multiplication of transatlantic circuits
all more or less close together, and, in consequence, all more or
less liable to interfere with each other under existing conditions.
Probably, however, any new company formed for the purposes of
telegraphic communication between different countries would not
confine itself--either in name or practise--to cables, but would also
cultivate the "wireless" system of telegraphy.
