Chapter 15

The next day, the 17th of April, the sailor’s first words were addressed

to Gideon Spilett.

“Well, sir,” he asked, “what shall we do to-day?”

“What the captain pleases,” replied the reporter.

Till then the engineer’s companions had been brickmakers and potters,

now they were to become metallurgists.

The day before, after breakfast, they had explored as far as the point

of Mandible Cape, seven miles distant from the Chimneys. There, the long

series of downs ended, and the soil had a volcanic appearance. There

were no longer high cliffs as at Prospect Heights, but a strange and

capricious border which surrounded the narrow gulf between the two

capes, formed of mineral matter, thrown up by the volcano. Arrived at

this point the settlers retraced their steps, and at nightfall entered

the Chimneys; but they did not sleep before the question of knowing

whether they could think of leaving Lincoln Island or not was definitely

settled.

The twelve hundred miles which separated the island from the Pomoutous

Island was a considerable distance. A boat could not cross it,

especially at the approach of the bad season. Pencroft had expressly

declared this. Now, to construct a simple boat even with the necessary

tools, was a difficult work, and the colonists not having tools they

must begin by making hammers, axes, adzes, saws, augers, planes, etc.,

which would take some time. It was decided, therefore, that they

would winter at Lincoln Island, and that they would look for a more

comfortable dwelling than the Chimneys, in which to pass the winter

months.

Before anything else could be done it was necessary to make the iron

ore, of which the engineer had observed some traces in the northwest

part of the island, fit for use by converting it either into iron or

into steel.

Metals are not generally found in the ground in a pure state. For the

most part they are combined with oxygen or sulphur. Such was the case

with the two specimens which Cyrus Harding had brought back, one of

magnetic iron, not carbonated, the other a pyrite, also called sulphuret

of iron. It was, therefore the first, the oxide of iron, which they must

reduce with coal, that is to say, get rid of the oxygen, to obtain it in

a pure state. This reduction is made by subjecting the ore with coal to

a high temperature, either by the rapid and easy Catalan method,

which has the advantage of transforming the ore into iron in a single

operation, or by the blast furnace, which first smelts the ore, then

changes it into iron, by carrying away the three to four per cent. of

coal, which is combined with it.

Now Cyrus Harding wanted iron, and he wished to obtain it as soon as

possible. The ore which he had picked up was in itself very pure and

rich. It was the oxydulous iron, which is found in confused masses of a

deep gray color; it gives a black dust, crystallized in the form of the

regular octahedron. Native lodestones consist of this ore, and iron

of the first quality is made in Europe from that with which Sweden and

Norway are so abundantly supplied. Not far from this vein was the vein

of coal already made use of by the settlers. The ingredients for the

manufacture being close together would greatly facilitate the treatment

of the ore. This is the cause of the wealth of the mines in Great

Britain, where the coal aids the manufacture of the metal extracted from

the same soil at the same time as itself.

“Then, captain,” said Pencroft, “we are going to work iron ore?”

“Yes, my friend,” replied the engineer, “and for that--something which

will please you--we must begin by having a seal hunt on the islet.”

“A seal hunt!” cried the sailor, turning towards Gideon Spilett. “Are

seals needed to make iron?”

“Since Cyrus has said so!” replied the reporter.

But the engineer had already left the Chimneys, and Pencroft prepared

for the seal hunt, without having received any other explanation.

Cyrus Harding, Herbert, Gideon Spilett, Neb, and the sailor were

soon collected on the shore, at a place where the channel left a ford

passable at low tide. The hunters could therefore traverse it without

getting wet higher than the knee.

Harding then put his foot on the islet for the first, and his companions

for the second time.

On their landing some hundreds of penguins looked fearlessly at them.

The hunters, armed with sticks, could have killed them easily, but they

were not guilty of such useless massacre, as it was important not to

frighten the seals, who were lying on the sand several cable lengths

off. They also respected certain innocent-looking birds, whose wings

were reduced to the state of stumps, spread out like fins, ornamented

with feathers of a scaly appearance. The settlers, therefore, prudently

advanced towards the north point, walking over ground riddled with

little holes, which formed nests for the sea-birds. Towards the

extremity of the islet appeared great black heads floating just above

the water, having exactly the appearance of rocks in motion.

These were the seals which were to be captured. It was necessary,

however, first to allow them to land, for with their close, short

hair, and their fusiform conformation, being excellent swimmers, it is

difficult to catch them in the sea, while on land their short, webbed

feet prevent their having more than a slow, waddling movement.

Pencroft knew the habits of these creatures, and he advised waiting till

they were stretched on the sand, when the sun, before long, would send

them to sleep. They must then manage to cut off their retreat and knock

them on the head.

The hunters, having concealed themselves behind the rocks, waited

silently.

An hour passed before the seals came to play on the sand. They could

count half a dozen. Pencroft and Herbert then went round the point of

the islet, so as to take them in the rear, and cut off their retreat.

During this time Cyrus Harding, Spilett, and Neb, crawling behind the

rocks, glided towards the future scene of combat.

All at once the tall figure of the sailor appeared. Pencroft shouted.

The engineer and his two companions threw themselves between the sea and

the seals. Two of the animals soon lay dead on the sand, but the rest

regained the sea in safety.

“Here are the seals required, captain!” said the sailor, advancing

towards the engineer.

“Capital,” replied Harding. “We will make bellows of them!”

“Bellows!” cried Pencroft. “Well! these are lucky seals!”

It was, in fact, a blowing-machine, necessary for the treatment of

the ore that the engineer wished to manufacture with the skins of the

amphibious creatures. They were of a medium size, for their length did

not exceed six feet. They resembled a dog about the head.

As it was useless to burden themselves with the weight of both the

animals, Neb and Pencroft resolved to skin them on the spot, while Cyrus

Harding and the reporter continued to explore the islet.

The sailor and the Negro cleverly performed the operation, and three

hours afterwards Cyrus Harding had at his disposal two seals’ skins,

which he intended to use in this state, without subjecting them to any

tanning process.

The settlers waited till the tide was again low, and crossing the

channel they entered the Chimneys.

The skins had then to be stretched on a frame of wood and sewn by means

of fibers so as to preserve the air without allowing too much to escape.

Cyrus Harding had nothing but the two steel blades from Top’s collar,

and yet he was so clever, and his companions aided him with so much

intelligence, that three days afterwards the little colony’s stock of

tools was augmented by a blowing-machine, destined to inject the air

into the midst of the ore when it should be subjected to heat--an

indispensable condition to the success of the operation.

On the morning of the 20th of April began the “metallic period,” as the

reporter called it in his notes. The engineer had decided, as has been

said, to operate near the veins both of coal and ore. Now, according to

his observations, these veins were situated at the foot of the northeast

spurs of Mount Franklin, that is to say, a distance of six miles from

their home. It was impossible, therefore, to return every day to the

Chimneys, and it was agreed that the little colony should camp under a

hut of branches, so that the important operation could be followed night

and day.

This settled, they set out in the morning. Neb and Pencroft dragged the

bellows on a hurdle; also a quantity of vegetables and animals, which

they besides could renew on the way.

The road led through Jacamar Wood, which they traversed obliquely from

southeast to northwest, and in the thickest part. It was necessary to

beat a path, which would in the future form the most direct road to

Prospect Heights and Mount Franklin. The trees, belonging to the species

already discovered, were magnificent. Herbert found some new ones, among

others some which Pencroft called “sham leeks”; for, in spite of their

size, they were of the same liliaceous family as the onion, chive,

shallot, or asparagus. These trees produce ligneous roots which, when

cooked, are excellent; from them, by fermentation, a very agreeable

liquor is made. They therefore made a good store of the roots.

The journey through the wood was long; it lasted the whole day, and so

allowed plenty of time for examining the flora and fauna. Top, who

took special charge of the fauna, ran through the grass and brushwood,

putting up all sorts of game. Herbert and Gideon Spilett killed two

kangaroos with bows and arrows, and also an animal which strongly

resembled both a hedgehog and an ant-eater. It was like the first

because it rolled itself into a ball, and bristled with spines, and the

second because it had sharp claws, a long slender snout which terminated

in a bird’s beak, and an extendible tongue, covered with little thorns

which served to hold the insects.

“And when it is in the pot,” asked Pencroft naturally, “what will it be

like?”

“An excellent piece of beef,” replied Herbert.

“We will not ask more from it,” replied the sailor.

During this excursion they saw several wild boars, which however, did

not offer to attack the little band, and it appeared as if they would

not meet with any dangerous beasts; when, in a thick part of the wood,

the reporter thought he saw, some paces from him, among the lower

branches of a tree, an animal which he took for a bear, and which he

very tranquilly began to draw. Happily for Gideon Spilett, the animal in

question did not belong to the redoubtable family of the plantigrades.

It was only a koala, better known under the name of the sloth, being

about the size of a large dog, and having stiff hair of a dirty color,

the paws armed with strong claws, which enabled it to climb trees and

feed on the leaves. Having identified the animal, which they did not

disturb, Gideon Spilett erased “bear” from the title of his sketch,

putting koala in its place, and the journey was resumed.

At five o’clock in the evening, Cyrus Harding gave the signal to halt.

They were now outside the forest, at the beginning of the powerful spurs

which supported Mount Franklin towards the west. At a distance of some

hundred feet flowed the Red Creek, and consequently plenty of fresh

water was within their reach.

The camp was soon organized. In less than an hour, on the edge of the

forest, among the trees, a hut of branches interlaced with creepers,

and pasted over with clay, offered a tolerable shelter. Their geological

researches were put off till the next day. Supper was prepared, a good

fire blazed before the hut, the roast turned, and at eight o’clock,

while one of the settlers watched to keep up the fire, in case any wild

beasts should prowl in the neighborhood, the others slept soundly.

The next day, the 21st of April, Cyrus Harding accompanied by Herbert,

went to look for the soil of ancient formation, on which he had already

discovered a specimen of ore. They found the vein above ground, near the

source of the creek, at the foot of one of the northeastern spurs. This

ore, very rich in iron, enclosed in its fusible veinstone, was perfectly

suited to the mode of reduction which the engineer intended to employ;

that is, the Catalan method, but simplified, as it is used in

Corsica. In fact, the Catalan method, properly so called, requires the

construction of kilns and crucibles, in which the ore and the coal,

placed in alternate layers, are transformed and reduced, But Cyrus

Harding intended to economize these constructions, and wished simply to

form, with the ore and the coal, a cubic mass, to the center of which he

would direct the wind from his bellows. Doubtless, it was the proceeding

employed by Tubalcain, and the first metallurgists of the inhabited

world. Now that which had succeeded with the grandson of Adam, and which

still yielded good results in countries rich in ore and fuel, could not

but succeed with the settlers in Lincoln Island.

The coal, as well as the ore, was collected without trouble on the

surface of the ground. They first broke the ore into little pieces,

and cleansed them with the hand from the impurities which soiled their

surface. Then coal and ore were arranged in heaps and in successive

layers, as the charcoal-burner does with the wood which he wishes to

carbonize. In this way, under the influence of the air projected by the

blowing-machine, the coal would be transformed into carbonic acid, then

into oxide of carbon, its use being to reduce the oxide of iron, that is

to say, to rid it of the oxygen.

Thus the engineer proceeded. The bellows of sealskin, furnished at its

extremity with a nozzle of clay, which had been previously fabricated

in the pottery kiln, was established near the heap of ore. Using the

mechanism which consisted of a frame, cords of fiber and counterpoise,

he threw into the mass an abundance of air, which by raising the

temperature also concurred with the chemical transformation to produce

in time pure iron.

The operation was difficult. All the patience, all the ingenuity of the

settlers was needed; but at last it succeeded, and the result was a lump

of iron, reduced to a spongy state, which it was necessary to shingle

and fagot, that is to say, to forge so as to expel from it the liquefied

veinstone. These amateur smiths had, of course, no hammer; but they were

in no worse a situation than the first metallurgist, and therefore did

what, no doubt, he had to do.

A handle was fixed to the first lump, and was used as a hammer to forge

the second on a granite anvil, and thus they obtained a coarse but

useful metal. At length, after many trials and much fatigue, on the 25th

of April several bars of iron were forged, and transformed into tools,

crowbars, pincers, pickaxes, spades, etc., which Pencroft and Neb

declared to be real jewels. But the metal was not yet in its most

serviceable state, that is, of steel. Now steel is a combination of iron

and coal, which is extracted, either from the liquid ore, by taking from

it the excess of coal, or from the iron by adding to it the coal which

was wanting. The first, obtained by the decarburation of the metal,

gives natural or puddled steel; the second, produced by the carburation

of the iron, gives steel of cementation.

It was the last which Cyrus Harding intended to forge, as he possessed

iron in a pure state. He succeeded by heating the metal with powdered

coal in a crucible which had previously been manufactured from clay

suitable for the purpose.

He then worked this steel, which is malleable both when hot or cold,

with the hammer. Neb and Pencroft, cleverly directed, made hatchets,

which, heated red-hot, and plunged suddenly into cold water, acquired an

excellent temper.

Other instruments, of course roughly fashioned, were also manufactured;

blades for planes, axes, hatchets, pieces of steel to be transformed

into saws, chisels; then iron for spades, pickaxes, hammers, nails,

etc. At last, on the 5th of May, the metallic period ended, the smiths

returned to the Chimneys, and new work would soon authorize them to take

a fresh title.
