TELLS OF GREAT EFFORTS AND FAILURES AND GRAND SUCCESS.

Thus happily and smoothly all things went, with little bursts of anxiety

and little touches of alarm, just sufficient, as it were, to keep up the

spirits of all, till the morning of the 30th July. But on that morning

an appearance of excitement in the testing-room told that something had

again gone wrong. Soon the order was given to slow the engines, then to

stop them!

The bursting of a thunder-clap, the explosion of a powder-magazine,

could not have more effectually awakened the slumberers than this abrupt

stoppage of the ship's engines. Instantly all the hatchways poured

forth anxious inquirers.

"Another fault," was the reply to such.

"O dear!" said some.

"Horrible!" said others.

"Not so bad as a break," sighed the hopeful spirits.

"It is bad enough," said the chief electrician, "for we have found dead

earth."

By this the chief meant to say that insulation had been completely

destroyed, and that the whole current of electricity was escaping into

the sea.

About 716 miles had been payed out at the time, and as signals had till

then been regularly received from the shore, it was naturally concluded

that the fault lay near to the ship.

"Now then, get along," said an engineer to one of the cable-men; "you'll

have to cut, and splice, and test, while we are getting ready the tackle

to pick up."

"I don't like that cuttin' o' the cable, Bill," said one of the sailors,

as he went forward, "it seems dangerous, it do."

"No more do I, Dick," replied his mate; "I feel as if it never could be

rightly spliced again."

"Why, bless you, boys," said a cable-man near them, "cables is used to

that now, like eels to bein' skinned; and so are we, for that matter.

We think nothin' of it."

Clearly the cable-man was right, for, while the picking-up apparatus was

being got ready, the cable was cut in no fewer than three places, in

order to test the coils that lay in the tanks. These being found all

right, the picking-up was begun with anxious care. The moment of

greatest danger was when the big ship was swinging round. For a few,

but apparently endless, moments the cable had to bear the strain, and

became rigid like a bar of steel. Then it was got in over the bows,

where all was bustle, and noise, and smoke, as the picking-up machinery

panted and rattled.

All day the work went on. Night descended, but still the cable was

coming in slowly, unwillingly,--now jerkily, as if half inclined to

yield, anon painfully, as if changing its mind, until the strain was

equal to two and a half tons. A row of lanterns lighted it, and the men

employed watched and handled it carefully to detect the "fault," while

the clattering wheels played harsh music.

"We'll never find it," growled an impatient young electrician.

As if to rebuke him for his want of faith, the "fault" came in then and

there--at 9:50 p.m., ship's time.

"Ah!" said Mr Field, whose chief characteristic was an unwavering faith

in ultimate success, "I knew we should find it are long. I have often

known cables to stop working for two hours, no one knew why, and then

begin again."

"Well now, Mr Wright, it floors me altogether, does this here talkin'

by electricity."

The man who made this remark to our hero was one who could not have been

easily "floored" by any other means than electricity. He was a huge

blacksmith--a stalwart fellow who had just been heaving the

sledge-hammer with the seeming powers of Vulcan himself, and who chanced

to be near Robin when he paused to rest and mop the streaming

perspiration from his brow, while a well-matched brother took his place

at the anvil.

"You see," he continued, "I can't make out nohow what the electricity

does when it gits through the cable from Ireland to Noofun'land. Of

course it don't actooally speak, you know--no more does it whistle, I

suppose; an' even if it did I don't see as we'd be much the wiser. What

_do_ it do, Mr Wright? You seem to be well up in these matters, an'

not above explainin' of 'em to the likes o' us as ha'n't got much

edication."

Few things pleased Robin more than being asked to impart what knowledge

he possessed, or to make plain subjects that were slightly complex. He

was not always successful in his attempts at elucidation, partly because

some subjects were too complex to simplify, and partly because some

intellects were obtuse, but he never failed to try.

"You must know," he replied, with that earnest look which was apt to

overspread his face when about to explain a difficulty, "that a piece of

common iron can be converted into a magnet by electrifying it, and it

can be unconverted just as fast by removing the electricity. Well,

suppose I have a bit of iron in America, with an electric battery in

Ireland, or _vice versa_--"

"W'ot's wicey wersa, Mr Wright?"

"Oh, it means the terms being changed--turned the other way, you know--

back to the front, as it were--in short, I mean the battery being in

America and the bit of iron in Ireland."

"Well, well, who'd a thought there was so much in wicey wersa; but go

on, Mr Wright."

"Now, you must suppose," continued Robin, "that a needle, like the

mariner's compass needle, hangs beside my bit of iron, close to it, and

that a wire, or conductor of electricity, connects the iron with my

electric battery in Ireland. Well, that makes a magnet of it, and the

suspended needle, being attracted, sticks to it. Then I disconnect the

wire from my battery by touching a handle, the bit of iron ceases to be

a magnet, and the needle was free. Again I connect the battery, and the

needle flies to the remagnetised bit of iron. Thus, as fast as I

choose, I can make the needle wag, and by a simple arrangement we can

make it wag right or left, so many beats right or left, or alternately,

representing letters. By varying the beats we vary the letters, and

thus spell out our messages. Now, do you understand it?"

"I ain't quite sure that I does," replied Vulcan; "I've got a hazy

notion that by touchin' and removin' the touch from a conductor,

connecting and disconnecting wires and batteries, you can make

electricity flow just as you let on or stop water by turnin' a

stopcock--"

"Not exactly," interrupted Robin, "because, you see, electricity does

not really flow, not being a substance."

"Not a substance, sir! w'y, w'ot is it then?"

"Like light and sound, it is merely an effect, an influence, a result,"

answered Robin. "We only use the word _flow_, and talk of electricity

as a fluid, for convenience' sake."

"Well, w'otever it is or isn't," continued the puzzled Vulcan, gazing at

vacancy for a few seconds, "when you've set it agoin'--or set agoin' the

things as sets it agoin'--you make a suspended needle wag, and when you

stop it you make the needle stop waggin', and by the way in which that

there needle wags you can spell out the letters o' the alphabit--so many

wags to the right bein' one letter, so many wags to the left bein'

another letter, an' so on,--so that, what between the number o' wags an'

the direction o' the waggin's, you--you come for to--there, I'm lost

again, an' I must go in for another spell wi' the sledge, so we'll have

to tackle the subject another time, Mr Wright."

Thus speaking, Vulcan seized the ponderous hammer in his powerful grasp

and proceeded to beat form into a mass of glowing metal with much

greater ease than he had been able to thump telegraphy into his own

brain.

In the discovery of the "fault" and the cutting out of the injured part

of the cable, twenty-six hours were lost. During all the time Captain

Anderson was obliged to remain on deck, while the minds and bodies of

the engineers and electricians were subjected to a severe strain for the

same period. They had scarcely begun to breathe freely again, and to

congratulate each other on being able to continue the voyage, when they

received another shock of alarm by the cable suddenly flying off the

drum, while it was being transferred from the picking-up machinery in

the bow to the paying-out arrangements in the stern. Before the

machinery could be stopped, some fathoms of cable had become entangled

among the wheels and destroyed. This part having been cut out, however,

and new splices made, the paying-out process was resumed.

"I'll turn in now and have a snooze, Robin," said Ebenezer Smith, "and

you had better do the same; you look tired."

This was indeed true, for not a man or boy in the ship took a more

anxious interest in the cable than did our little hero; he had begun to

regard it as a living creature, and to watch over it, and dream about

it, as if it were a dear friend in extreme danger. The enthusiastic boy

was actually becoming careworn and thin, for he not only performed all

the duties required of him with zealous application, but spent his

leisure, and much of the time that should have been devoted to rest, in

the careful study of his idol--intensely watching it, and all that was

in the remotest way connected with it.

"You're a goose," said Stumps, in passing, when he heard Robin decline

to retire as Smith had advised him.

"It may be so, and if so, Stumps, I shall continue to cackle a little

longer on deck while they are examining the fault."

That examination, when finished, produced a considerable sensation. The

process was conducted in private. The condemned portion was cut in

junks and tested, until the faulty junk was discovered. This was

untwisted until the core was laid bare, and when about a foot of it had

been so treated, the cause of evil was discovered, drawing from the

onlookers an exclamation of horror rather than surprise, as they stood

aghast, for _treachery_ seemed to have been at work!

"An enemy in the ship!" murmured one.

"What ship without an enemy?" thought another.

That mischief had been intended was obvious, for a piece of iron wire,

bright as if cut with nippers at one end and broken off short at the

other, had been driven right through the centre of the cable, so as to

touch the inner wires--thus forming a leak, or conductor, into the sea.

There could be no doubt that it had not got there by accident; neither

had it been driven there during the making or shipping of the cable, for

in that case the testings for continuity would have betrayed its

presence before the starting of the expedition. The piece of wire, too,

was the same size as that which formed the protecting cover, and it was

of the exact diameter of the cable. There was also the mark of a cut on

the Manilla hemp, where the wire had entered. It could have been done

only by one of the men who were at work in the tank at the time the

portion went over, and, strange to say, this was the same gang which had

been at work there when the previous "fault" occurred.

"Call all the men aft," was the order that quickly followed this

discovery.

The piece of cable was handed to them, and they were allowed to examine

it in silence. They did so in great surprise, mingled with indignation.

"It's bin done a'purpose, an' driven in by a skilful hand," said one.

"You're right, Joe," said another.

"I knows," whispered a third, "that _one_ of the men expressed

satisfaction when the last fault occurred, an' I've heard say that we've

got enemies to the makers o' the cable aboard."

The man thus darkly referred to, whoever he was, of course looked as

innocent and as indignant as the most virtuous among them; the guilt,

therefore, could not be brought home to him. Woe betide him if it had

been, for there was a serious talk of lynching some one among the

wrathful men, each of whom was now subject to suspicion.

In these trying circumstances, the chief engineer accepted an offer made

by the gentlemen in the ship, to take turn about in superintending the

men at work in the tank paying-out the cable.

"It's not pleasant, of course," replied one of the men, speaking for the

rest, "but we feel it to be justifiable, as well as necessary, and are

very glad the plan has been adopted."

Once more the big ship went merrily on her way, and the great cable went

down to its ocean-bed so smoothly and regularly, that men began to talk

of speedy arrival at Heart's Content--their destination in

Newfoundland--which was now only about 600 miles distant; but their

greatest troubles still lay before them. About eight o'clock in the

morning of 2nd August another bad fault was reported, and they had once

again to resort to the wearisome process of picking-up.

At first all seemed about to go well. A gale was indeed blowing at the

time, but that did not much affect the colossal ship. The cable was

cut, fastened to its iron rope, passed to the bow, and got in over the

pulleys. Then, and very slowly, it was drawn on board. When a mile or

so had been recovered, the gearing of one of the engines got a little

out of order, and the process had to be temporarily stopped; then

something went wrong with the boilers, but soon these difficulties were

removed. Immediately after, the Great Eastern drifted, so that it was

impossible to prevent the cable from chafing against her bows. Equally

impossible was it to go astern, lest the strain should be too great.

Then the wind suddenly shifted, making matters worse. Suddenly the

chain shackle and wire-rope attached to the cable came in over the wheel

at the bows with considerable violence. Another moment and the cable

parted, flew through the stoppers, and, with one bound, flashed into the

sea and disappeared!

Now, at last, the fatal climax so much dreaded had arrived. The days

and nights of anxious labour had been spent in vain. The cable was

lost, and with it went not only hundreds of thousands of pounds, but the

hopes of hundreds of thousands of people, whose sanguine expectations of

success were thus rudely dispelled.

Need it be said that something very like despair reigned for the moment

on board the Great Eastern?

Most of the gentlemen on board--never dreaming of catastrophe--were at

luncheon, when Mr Canning entered the saloon with a look that caused

every one to start.

"It is all over!--it is gone!" he said, and hastened to his cabin.

Mr Field, with the composure of faith and courage, though very pale,

entered the saloon immediately after, and confirmed the chief engineer's

statement.

"The cable has parted," he said, "and has gone overboard."

From the chiefs down even to Stumps and his fraternity all was blank

dismay! As for our hero Robin Wright, he retired to his cabin, flung

himself on his bed, and sobbed as though his heart would break.

But such a state of things could not last. Men's spirits may be stunned

and crushed, but they are seldom utterly overwhelmed so long as life

endures.

Recovering from the shock, Mr Canning set about the process of

grappling for the lost cable with persistent energy. But fishing in

water two and a half miles deep is no easy matter. Nevertheless, it was

done. Again and again, and over again, were two monster hooks in the

shape of grapnels let down to the bottom of the sea, with an iron rope

for a line, and the Great Eastern for a float!

The plan, of course, was to go back a few miles on their course and then

drag across the known position of the lost treasure.

We say known, because good observations had fortunately been obtained by

Captain Anderson just before the accident.

Two hours did the grapnels descend before they reached the bottom of the

sea! All night did the cable-layers fish, with the characteristic

patience of fishermen, but did not get a nibble. Towards morning,

however, there was a decided bite, and the line became taut.

"Got him!" exclaimed an enthusiast eagerly.

"Don't be too sure," replied a philosopher cautiously.

"It may be a bit of wreck," suggested Ebenezer Smith, who was a natural

doubter.

"Or a whale, or the great sea-serpent," said the sporting electrician,

who was everything by turns and nothing long.

"We shall very soon know," remarked a matter-of-fact engineer. "If it

is a loose object the strain will decrease as it nears the surface, but

if it be the cable the strain will certainly increase, because its

weight will be greater the more of it we lift off the bottom."

Earnestly did every one regard the dynamometer which told the exact

amount of strain on the iron fishing-line, and to their joy the strain

_increased_ until the object caught had been raised three-quarters of a

mile from the bottom. Then a swivel gave way, and the cable went back

to its ocean-bed.

But those plucky engineers were not to be overcome by a first failure.

Having started with five miles of fishing-line, they proceed at once to

make a second attempt.

"Oh, I _do_ hope they will hook it again!" said Robin Wright.

"And so they will," said Ebenezer Smith.

And so they did. Late in the afternoon of the Monday following, their

fish was again hooked and raised a full mile from the bottom, when

another swivel gave way, and down it went a second time!

The fishing-line was now getting short. It behoved them to act with

more caution. New bolts were put in each shackle and swivel, and the

capstan was increased in diameter, being belted with thick plates of

iron. To effect these alterations the forges had to be erected on deck,

and at night these cast a lurid glare on the busy workers, bringing out

every near object in vivid relief against the ebony background of space

behind, while they made preparations for a third cast of the

fishing-line. The cast was made successfully, it was thought, but one

of the grapnels had caught the line with one of its flukes, so that it

could not catch anything else, and the result was--nothing.

A fourth attempt was then made. It was to be the last. The

fishing-line seemed too weak, and its frequent breakings had reduced it

so much that other chains had to be attached to it. With this thing of

shreds and patches the cable was once more hooked and brought up nearly

eight hundred fathoms, when the line gave way once more, and the cable

went down for the last time.

Nothing more could be done. The Great Eastern turned her large bows to

the east and steered grandly though sadly, away for old England.

But don't imagine, good reader, that these cable-layers were beaten.

They were baffled, indeed, for that year (1865), but not conquered.

Cyrus Field had resolved that the thing should be done--and done it was

the following year; for the laying of the cable had been so nearly a

success, that great capitalists, such as Brassey, Gooch, Barclay,

Campbell, Pender, and others, at once came forward. Among these were

the contractors, Glass and Elliot, who agreed not only to make and lay a

new cable, but to pick up and complete the old one. Cyrus Field

himself, besides energising like Hercules to push the matter on, was one

of ten subscribers who each contributed 10,000 pounds. Thus 230,500

pounds were privately subscribed before a prospectus was issued.

Our little hero was at the laying of that (1866) cable, when the same

great ship, with the same captain and most of the engineers and

electricians who had gone out on the previous voyage, landed the end of

the 1820-mile rope on the shores of Newfoundland, on Friday, 27th July.

He cheered with the rest in wild enthusiasm when the Great Eastern

dropped anchor in "Heart's Content." He accompanied Captain Anderson

and the officers of the fleet when they went in a body to the little

church there, to thank God for the successful completion of the great

enterprise. He was present when the big ship, having received from

other ships 8000 tons of coal, and some six hundred miles of the old

cable, went back to mid-ocean to grapple for the lost cable of 1865. He

assisted and watched with the deepest interest the amazing efforts of

scientific and mechanical power put forth in the mere matter of dragging

for the cable from the bottom, and observed with reverence, amounting

almost to awe, the great moving spirit of the whole affair, the

indomitable Mr Field, as he went to the bow and sat on the rope to feel

the quiver which told him it was dragging the bottom of the sea two

miles below. He was present, with blazing cheeks and eyes and bated

breath, when, on the 17th of August, the cable was caught, dragged to

the surface, and actually seen, and broke and sank again as deep as

ever--though not so deep as the hearts of those who saw it go! He

shared in the weary delays that followed, and in the final triumph when

the cable was fairly caught and at last brought on board, and carried to

the testing-room, amid intense excitement, lest it should prove to have

been damaged by its rough treatment; and his voice helped to swell the

roar of enthusiastic cheering that greeted the announcement that the old

cable was still alive!

But all this we must leave, and carry the reader back to old England

faster than the Great Eastern could have rushed--ay, faster than the

message on the flashing cable itself could have sped, for mind is more

subtle than matter, and thought is swifter than even the Atlantic

Telegraph.
