The Mysterious Island
The works were then resumed. Cyrus Harding, Pencroft, and Ayrton,
assisted by Neb, Gideon Spilett, and Herbert, except when unavoidably
called off by other necessary occupations, worked without cessation. It
was important that the new vessel should be ready in five months--that
is to say, by the beginning of March--if they wished to visit Tabor
Island before the equinoctial gales rendered the voyage impracticable.
Therefore the carpenters lost not a moment. Moreover, it was unnecessary
to manufacture rigging, that of the “Speedy” having been saved entire,
so that the hull only of the vessel needed to be constructed.
The end of the year 1868 found them occupied by these important labors,
to the exclusion of almost all others. At the expiration of two months
and a half the ribs had been set up and the first planks adjusted. It
was already evident that the plans made by Cyrus Harding were admirable,
and that the vessel would behave well at sea.
Pencroft brought to the task a devouring energy, and would even grumble
when one or the other abandoned the carpenter’s axe for the gun of the
hunter. It was nevertheless necessary to keep up the stores of Granite
House, in view of the approaching winter. But this did not satisfy
Pencroft. The brave, honest sailor was not content when the workmen were
not at the dockyard. When this happened he grumbled vigorously, and, by
way of venting his feelings, did the work of six men.
The weather was very unfavorable during the whole of the summer season.
For some days the heat was overpowering, and the atmosphere, saturated
with electricity, was only cleared by violent storms. It was rarely that
the distant growling of the thunder could not be heard, like a low but
incessant murmur, such as is produced in the equatorial regions of the
globe.
The 1st of January, 1869, was signalized by a storm of extreme violence,
and the thunder burst several times over the island. Large trees were
struck by the electric fluid and shattered, and among others one of
those gigantic nettle-trees which had shaded the poultry-yard at the
southern extremity of the lake. Had this meteor any relation to the
phenomena going on in the bowels of the earth? Was there any connection
between the commotion of the atmosphere and that of the interior of the
earth? Cyrus Harding was inclined to think that such was the case, for
the development of these storms was attended by the renewal of volcanic
symptoms.
It was on the 3rd of January that Herbert, having ascended at daybreak
to the plateau of Prospect Heights to harness one of the onagers,
perceived an enormous hat-shaped cloud rolling from the summit of the
volcano.
Herbert immediately apprised the colonists, who at once joined him in
watching the summit of Mount Franklin.
“Ah!” exclaimed Pencroft, “those are not vapors this time! It seems to
me that the giant is not content with breathing; he must smoke!”
This figure of speech employed by the sailor exactly expressed the
changes going on at the mouth of the volcano. Already for three months
had the crater emitted vapors more or less dense, but which were as yet
produced only by an internal ebullition of mineral substances. But
now the vapors were replaced by a thick smoke, rising in the form of a
grayish column, more than three hundred feet in width at its base, and
which spread like an immense mushroom to a height of from seven to eight
hundred feet above the summit of the mountain.
“The fire is in the chimney,” observed Gideon Spilett.
“And we can’t put it out!” replied Herbert.
“The volcano ought to be swept,” observed Neb, who spoke as if perfectly
serious.
“Well said, Neb!” cried Pencroft, with a shout of laughter; “and you’ll
undertake the job, no doubt?”
Cyrus Harding attentively observed the dense smoke emitted by Mount
Franklin, and even listened, as if expecting to hear some distant
muttering. Then, turning towards his companions, from whom he had gone
somewhat apart, he said,--
“The truth is, my friends, we must not conceal from ourselves that an
important change is going forward. The volcanic substances are no longer
in a state of ebullition, they have caught fire, and we are undoubtedly
menaced by an approaching eruption.”
“Well, captain,” said Pencroft, “we shall witness the eruption; and if
it is a good one, we’ll applaud it. I don’t see that we need concern
ourselves further about the matter.”
“It may be so,” replied Cyrus Harding, “for the ancient track of
the lava is still open; and thanks to this, the crater has hitherto
overflowed towards the north. And yet--”
“And yet, as we can derive no advantage from an eruption, it might be
better it should not take place,” said the reporter.
“Who knows?” answered the sailor. “Perhaps there may be some valuable
substance in this volcano, which it will spout forth, and which we may
turn to good account!”
Cyrus Harding shook his head with the air of a man who augured no good
from the phenomenon whose development had been so sudden. He did not
regard so lightly as Pencroft the results of an eruption. If the lava,
in consequence of the position of the crater, did not directly menace
the wooded and cultivated parts of the island, other complications might
present themselves. In fact, eruptions are not unfrequently accompanied
by earthquakes; and an island of the nature of Lincoln Island, formed of
substances so varied, basalt on one side, granite on the other, lava on
the north, rich soil on the south, substances which consequently could
not be firmly attached to each other, would be exposed to the risk
of disintegration. Although, therefore, the spreading of the volcanic
matter might not constitute a serious danger, any movement of the
terrestrial structure which should shake the island might entail the
gravest consequences.
“It seems to me,” said Ayrton, who had reclined so as to place his ear
to the ground, “it seems to me that I can hear a dull, rumbling sound,
like that of a wagon loaded with bars of iron.”
The colonists listened with the greatest attention, and were convinced
that Ayrton was not mistaken. The rumbling was mingled with a
subterranean roar, which formed a sort of rinforzando, and died slowly
away, as if some violent storm had passed through the profundities of
the globe. But no explosion properly so termed, could be heard. It might
therefore be concluded that the vapors and smoke found a free passage
through the central shaft; and that the safety-valve being sufficiently
large, no convulsion would be produced, no explosion was to be
apprehended.
“Well, then!” said Pencroft, “are we not going back to work? Let Mount
Franklin smoke, groan, bellow, or spout forth fire and flame as much as
it pleases, that is no reason why we should be idle! Come, Ayrton, Neb,
Herbert, Captain Harding, Mr. Spilett, every one of us must turn to at
our work to-day! We are going to place the keelson, and a dozen pair
of hands would not be too many. Before two months I want our new
‘Bonadventure’--for we shall keep the old name, shall we not?--to float
on the waters of Port Balloon! Therefore there is not an hour to lose!”
All the colonists, their services thus requisitioned by Pencroft,
descended to the dockyard, and proceeded to place the keelson, a thick
mass of wood which forms the lower portion of a ship and unites firmly
the timbers of the hull. It was an arduous undertaking, in which all
took part.
They continued their labors during the whole of this day, the 3rd of
January, without thinking further of the volcano, which could not,
besides, be seen from the shore of Granite House. But once or twice,
large shadows, veiling the sun, which described its diurnal arc through
an extremely clear sky, indicated that a thick cloud of smoke passed
between its disc and the island. The wind, blowing on the shore, carried
all these vapors to the westward. Cyrus Harding and Gideon Spilett
remarked these somber appearances, and from time to time discussed
the evident progress of the volcanic phenomena, but their work went
on without interruption. It was, besides, of the first importance from
every point of view, that the vessel should be finished with the least
possible delay. In presence of the eventualities which might arise,
the safety of the colonists would be to a great extent secured by their
ship. Who could tell that it might not prove some day their only refuge?
In the evening, after supper, Cyrus Harding, Gideon Spilett, and Herbert
again ascended the plateau of Prospect Heights. It was already dark, and
the obscurity would permit them to ascertain if flames or incandescent
matter thrown up by the volcano were mingled with the vapor and smoke
accumulated at the mouth of the crater.
“The crater is on fire!” said Herbert, who, more active than his
companion, first reached the plateau.
Mount Franklin, distant about six miles, now appeared like a gigantic
torch, around the summit of which turned fuliginous flames. So much
smoke, and possibly scoriae and cinders were mingled with them, that
their light gleamed but faintly amid the gloom of the night. But a kind
of lurid brilliancy spread over the island, against which stood out
confusedly the wooded masses of the heights. Immense whirlwinds of vapor
obscured the sky, through which glimmered a few stars.
“The change is rapid!” said the engineer.
“That is not surprising,” answered the reporter. “The reawakening of the
volcano already dates back some time. You may remember, Cyrus, that
the first vapors appeared about the time we searched the sides of the
mountain to discover Captain Nemo’s retreat. It was, if I mistake not,
about the 15th of October.”
“Yes,” replied Herbert, “two months and a half ago!”
“The subterranean fires have therefore been smoldering for ten weeks,”
resumed Gideon Spilett, “and it is not to be wondered at that they now
break out with such violence!”
“Do not you feel a certain vibration of the soil?” asked Cyrus Harding.
“Yes,” replied Gideon Spilett, “but there is a great difference between
that and an earthquake.”
“I do not affirm that we are menaced with an earthquake,” answered Cyrus
Harding, “may God preserve us from that! No; these vibrations are due to
the effervescence of the central fire. The crust of the earth is
simply the shell of a boiler, and you know that such a shell, under the
pressure of steam, vibrates like a sonorous plate. It is this effect
which is being produced at this moment.”
“What magnificent flames!” exclaimed Herbert.
At this instant a kind of bouquet of flames shot forth from the crater,
the brilliancy of which was visible even through the vapors. Thousands
of luminous sheets and barbed tongues of fire were cast in various
directions. Some, extending beyond the dome of smoke, dissipated
it, leaving behind an incandescent powder. This was accompanied
by successive explosions, resembling the discharge of a battery of
machine-guns.
Cyrus Harding, the reporter, and Herbert, after spending an hour on the
plateau of Prospect Heights, again descended to the beach, and returned
to Granite House. The engineer was thoughtful and preoccupied, so much
so, indeed, that Gideon Spilett inquired if he apprehended any immediate
danger, of which the eruption might directly or indirectly be the cause.
“Yes, and no,” answered Cyrus Harding.
“Nevertheless,” continued the reporter, “would not the greatest
misfortune which could happen to us be an earthquake which would
overturn the island? Now, I do not suppose that this is to be feared,
since the vapors and lava have found a free outlet.”
“True,” replied Cyrus Harding, “and I do not fear an earthquake in the
sense in which the term is commonly applied to convulsions of the soil
