"Mr Harding, I wish to speak with you--alone!"

The engineer's companions, respecting the wish of the dying man, retired.

Cyrus Harding remained but a few minutes alone with Captain Nemo, and soon recalled his companions; but he said nothing to them of the private matters which the dying man had confided to him.

Gideon Spilett now watched the captain with extreme care. It was evident that he was no longer sustained by his moral energy, which had lost the power of reaction against his physical weakness.

The day closed without change. The colonists did not quit the _Nautilus_ for a moment. Night arrived, although it was impossible to distinguish it from day in the cavern.

Captain Nemo suffered no pain, but he was visibly sinking. His n.o.ble features, paled by the approach of death, were perfectly calm.

Inaudible words escaped at intervals from his lips, bearing upon various incidents of his chequered career. Life was evidently ebbing slowly, and his extremities were already cold.

Once or twice more he spoke to the colonists who stood around him, and smiled on them with that last smile which continues after death.

At length, shortly after midnight, Captain Nemo by a supreme effort succeeded in folding his arms across his breast, as if wishing in that att.i.tude to compose himself for death.

By one o'clock his glance alone showed signs of life. A dying light gleamed in those eyes once so brilliant. Then, murmuring the words, "G.o.d and my country!" he quietly expired.

Cyrus Harding, bending low, closed the eyes of him who had once been the Prince Dakkar, and was now not even Captain Nemo.

Herbert and Pencroft sobbed aloud. Tears fell from Ayrton's eyes. Neb was on his knees by the reporter's side, motionless as a statue.

Then Cyrus Harding, extending his hand over the forehead of the dead, said solemnly--

"May his soul be with G.o.d! Let us pray!"

Some hours later the colonists fulfilled the promise made to the captain by carrying out his dying wishes.

Cyrus Harding and his companions quitted the _Nautilus_, taking with them the only memento left them by their benefactor, that coffer which contained wealth amounting to millions.

The marvellous saloon, still flooded with light, had been carefully closed. The iron door leading on deck was then securely fastened in such a manner as to prevent even a drop of water from penetrating to the interior of the _Nautilus_.

The colonists then descended into the canoe, which was moored to the side of the submarine vessel.

The canoe was now brought round to the stern. There, at the water-line, were two large stop-c.o.c.ks, communicating with the reservoirs employed in the submersion of the vessel.

The stop-c.o.c.ks were opened, the reservoirs filled, and the _Nautilus_, slowly sinking, disappeared beneath the surface of the lake.

But the colonists were yet able to follow its descent through the waves.

The powerful light it gave forth lighted up the translucent water, while the cavern became gradually obscure. At length this vast effusion of electric light faded away, and soon after the _Nautilus_, now the tomb of Captain Nemo, reposed in its ocean bed.

CHAPTER EIGHTEEN.

REFLECTIONS OF THE COLONISTS--THEIR LABOURS OF RECONSTRUCTION RESUMED-- THE 1ST OF JANUARY 1869--A CLOUD OVER THE SUMMIT OF THE VOLCANO--FIRST WARNINGS OF AN ERUPTION--AYRTON AND CYRUS HARDING AT THE CORRAL-- EXPLORATION OF THE DAKKAR GROTTO--WHAT CAPTAIN NEMO HAD CONFIDED TO THE ENGINEER.

At break of day the colonists regained in silence the entrance of the cavern, to which they gave the name of "Dakkar Grotto," in memory of Captain Nemo. It was now low-water, and they pa.s.sed without difficulty under the arcade, washed on the right by the sea.

The canoe was left here, carefully protected from the waves. As an excess of precaution, Pencroft, Neb, and Ayrton drew it up on a little beach which bordered one of the sides of the grotto, in a spot where it could run no risk of harm.

The storm had ceased during the night. The last low mutterings of the thunder died away in the west. Rain fell no longer, but the sky was yet obscured by clouds. On the whole, this month of October, the first of the southern spring, was not ushered in by satisfactory tokens, and the wind had a tendency to shift from one point of the compa.s.s to another, which rendered it impossible to count upon settled weather.

Cyrus Harding and his companions, on leaving Dakkar Grotto, had taken the road to the corral. On their way Neb and Herbert were careful to preserve the wire which had been laid down by the captain between the corral and the grotto, and which might at a future time be of service.

The colonists spoke but little on the road. The various incidents of the night of the 15th October had left a profound impression on their minds. The unknown being whose influence had so effectually protected them, the man whom their imagination had endowed with supernatural powers, Captain Nemo, was no more. His _Nautilus_ and he were buried in the depths of the abyss. To each one of them their existence seemed even more isolated than before. They had been accustomed to count upon the intervention of that power which existed no longer, and Gideon Spilett, and even Cyrus Harding, could not escape this impression. Thus they maintained a profound silence during their journey to the corral.

Towards nine in the morning the colonists arrived at Granite House.

It had been agreed that the construction of the vessel should be actively pushed forward, and Cyrus Harding more than ever devoted his time and labour to this object. It was impossible to divine what future lay before them. Evidently the advantage to the colonists would be great of having at their disposal a substantial vessel, capable of keeping the sea even in heavy weather, and large enough to attempt, in case of need, a voyage of some duration. Even if, when their vessel should be completed, the colonists should not resolve to leave Lincoln Island as yet, in order to gain either one of the Polynesian archipelagos of the Pacific or the sh.o.r.es of New Zealand, they might at least, sooner or later, proceed to Tabor Island, to leave there the notice relating to Ayrton. This was a precaution rendered indispensable by the possibility of the Scotch yacht reappearing in those seas, and it was of the highest importance that nothing should be neglected on this point.

The works were then resumed. Cyrus Harding, Pencroft, and Ayrton, a.s.sisted 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 labours, 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 scrupled not to 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 unfavourable 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 signalised 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 micocouliers which 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 onagas, 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 vapours 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 vapours more or less dense, but which were as yet produced only by an internal ebullition of mineral substances. But now the vapours were replaced by a thick smoke, rising in the form of a greyish 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. .h.i.therto 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.
