"Well!" answered Pencroft, "I agree with you that the n.o.bleman will return, and soon too. But where will he touch? At Tabor Island, and not at Lincoln Island."

"That is the more certain," replied Herbert, "as Lincoln Island is not even marked on the map."

"Therefore, my friends," said the engineer, "we ought to take the necessary precautions for making our presence, and that of Ayrton on Lincoln Island known at Tabor Island."

"Certainly," answered the reporter, "and nothing is easier than to place in the hut, which was Captain Grant's and Ayrton's dwelling, a notice which Lord Glenarvan and his crew cannot help finding, giving the position of our island."

"It is a pity," remarked the sailor, "that we forgot to take that precaution on our first visit to Tabor Island."

"And why should we have done it?" asked Herbert.

"At that time we did not know Ayrton's history; we did not know that any one was likely to come some day to fetch him; and when we did know his history, the season was too advanced to allow us to return then to Tabor Island."

"Yes," replied Harding, "it was too late, and we must put off the voyage until next spring."

"But suppose the Scotch yacht comes before that," said Pencroft.

"That is not probable," replied the engineer, "for Lord Glenarvan would not choose the winter season to venture into these seas. Either he has already returned to Tabor Island, since Ayrton has been with us, that is to say, during the last five months and has left again; or he will not come till later, and it will be time enough in the first fine October days to go to Tabor Island, and leave a notice there."

"We must allow," said Neb, "that it will be very unfortunate if the Duncan has returned to these parts only a few months ago!"

"I hope that it is not so," replied Cyrus Harding, "and that Heaven has not deprived us of the best chance which remains to us."

"I think," observed the reporter, "that at any rate we shall know what we have to depend on when we have been to Tabor Island, for if the yacht has returned there, they will necessarily have left some traces of their visit."

"That is evident," answered the engineer. "So then, my friends, since we have this chance of returning to our country, we must wait patiently, and if it is taken from us we shall see what will be best to do."

"At any rate," remarked Pencroft, "it is well understood that if we do leave Lincoln Island in some way or another, it will not be because we were uncomfortable there!"

"No, Pencroft," replied the engineer, "it will be because we are far from all that a man holds dearest in this world, his family, his friends, his native land!"

Matters being thus decided, the building of a vessel large enough to sail either to the Archipelagos in the north, or to New Zealand in the west, was no longer talked of, and they busied themselves in their accustomed occupations, with a view to wintering a third time in Granite House.

However, it was agreed that before the stormy weather came on, their little vessel should be employed in making a voyage round the island. A complete survey of the coast had not yet been made, and the colonists had but an imperfect idea of the sh.o.r.e to the west and north, from the mouth of Falls River to the Mandible Capes, as well as of the narrow bay between them, which opened like a shark's jaws.

The plan of this excursion was proposed by Pencroft, and Cyrus Harding fully acquiesced in it, for he himself wished to see this part of his domain.

The weather was variable, but the barometer did not fluctuate by sudden movements, and they could therefore count on tolerable weather. However, during the first week of April, after a sudden barometrical fall, a renewed rise was marked by a heavy gale of wind, lasting five or six days; then the needle of the instrument remained stationary at a height of twenty-nine inches and nine-tenths, and the weather appeared propitious for an excursion.

The departure was fixed for the 16th of April, and the Bonadventure, anch.o.r.ed in Port Balloon, was provisioned for a voyage which might be of some duration.

Cyrus Harding informed Ayrton of the projected expedition, and proposed that he should take part in it; but Ayrton preferring to remain on sh.o.r.e, it was decided that he should come to Granite House during the absence of his companions. Master Jup was ordered to keep him company, and made no remonstrance.

On the morning of the 16th of April all the colonists, including Top, embarked. A fine breeze blew from the south-west, and the Bonadventure tacked on leaving Port Balloon so as to reach Reptile End. Of the ninety miles which the perimeter of the island measured, twenty included the south coast between the port and the promontory. The wind being right ahead, it was necessary to hug the sh.o.r.e.

It took the whole day to reach the promontory, for the vessel on leaving port had only two hours of the ebb tide, and had therefore to make way for six hours against the flood. It was nightfall before the promontory was doubled.

The sailor then proposed to the engineer that they should continue sailing slowly with two reefs in the sail. But Harding preferred to anchor a few cable-lengths from the sh.o.r.e, so as to survey that part of the coast during the day. It was agreed also that as they were anxious for a minute exploration of the coast they should not sail during the night, but would always, when the weather permitted it, be at anchor near the sh.o.r.e.

The night was pa.s.sed under the promontory, and the wind having fallen, nothing disturbed the silence. The pa.s.sengers, with the exception of the sailor, scarcely slept as well on board the Bonadventure as they would have done in their rooms at Granite House, but they did sleep however. Pencroft set sail at break of day, and by going on the larboard tack they could keep close to the sh.o.r.e.

The colonists knew this beautiful wooded coast, since they had already explored it on foot, and yet it again excited their admiration. They coasted along as close in as possible, so as to notice everything, avoiding always the trunks of trees which floated here and there. Several times also they anch.o.r.ed, and Gideon Spilett took photographs of the superb scenery.

About noon the Bonadventure arrived at the mouth of Falls River. Beyond, on the left bank, a few scattered trees appeared, and three miles further even these dwindled into solitary groups among the western spurs of the mountain, whose arid ridge sloped down to the sh.o.r.e.

What a contrast between the northern and southern part of the coast! In proportion as one was woody and fertile so was the other rugged and barren! It might have been designated as one of those iron coasts, as they are called in some countries, and its wild confusion appeared to indicate that a sudden crystallisation had been produced in the yet liquid basalt of some distant geological sea. These stupendous ma.s.ses would have terrified the settlers if they had been cast at first on this part of the island! They had not been able to perceive the sinister aspect of this sh.o.r.e from the summit of Mount Franklin, for they overlooked it from too great a height, but viewed from the sea it presented a wild appearance which could not perhaps be equalled in any corner of the globe.

The Bonadventure sailed along this coast for the distance of half a mile. It was easy to see that it was composed of blocks of all sizes, from twenty to three hundred feet in height, and of all shapes, round like towers, prismatic like steeples, pyramidal like obelisks, conical like factory chimneys. An iceberg of the Polar seas could not have been more capricious in its terrible sublimity! Here, bridges were thrown from one rock to another; there, arches like those of a wave, into the depths of which the eye could not penetrate; in one place, large vaulted excavations presented a monumental aspect; in another, a crowd of columns, spires, and arches, such as no Gothic cathedral ever possessed. Every caprice of nature, still more varied than those of the imagination, appeared on this grand coast, which extended over a length of eight or nine miles.

Cyrus Harding and his companions gazed, with a feeling of surprise bordering on stupefaction. But, although they remained silent, Top, not being troubled with feelings of this sort, uttered barks which were repeated by the thousand echoes of the basaltic cliff. The engineer even observed that these barks had something strange in them, like those which the dog had uttered at the mouth of the well in Granite House.

"Let us go close in," said he.

And the Bonadventure sailed as near as possible to the rocky sh.o.r.e. Perhaps some cave, which it would be advisable to explore, existed there? But Harding saw nothing, not a cavern, not a cleft which could serve as a retreat to any being whatever, for the foot of the cliff was washed by the surf. Soon Top's barks ceased, and the vessel continued her course at a few cable-lengths from the coast.

In the north-west part of the island the sh.o.r.e became again flat and sandy. A few trees here and there rose above a low, marshy ground, which the colonists had already surveyed; and in violent contrast to the other desert sh.o.r.e, life was again manifested by the presence of myriads of water-fowl. That evening the Bonadventure anch.o.r.ed in a small bay to the north of the island, near the land, such was the depth of water there. The night pa.s.sed quietly, for the breeze died away with the last light of day, and only rose again with the first streaks of dawn.

As it was easy to land, the usual hunters of the colony, that is to say, Herbert and Gideon Spilett, went for a ramble of two hours or so, and returned with several strings of wild duck and snipe. Top had done wonders, and not a bird had been lost, thanks to his zeal and cleverness.

At eight o'clock in the morning the Bonadventure set sail, and ran rapidly towards North Mandible Cape, for the wind was right astern and freshening rapidly.

"However," observed Pencroft, "I should not be surprised if a gale came up from the west. Yesterday the sun set in a very red-looking horizon, and now, this morning, those mares-tails don't forebode anything good."

These mares-tails are cirrus clouds, scattered in the zenith, their height from the sea being less than five thousand feet. They look like light pieces of cotton wool, and their presence usually announces some sudden change in the weather.

"Well," said Harding, "let us carry as much sail as possible, and run for shelter into Shark Gulf. I think that the Bonadventure will be safe there."

"Perfectly," replied Pencroft, "and besides, the north coast is merely sand, very uninteresting to look at."

"I shall not be sorry," resumed the engineer, "to pa.s.s not only to-night but to-morrow in that bay, which is worth being carefully explored."

"I think that we shall be obliged to do so, whether we like it or not," answered Pencroft, "for the sky looks very threatening towards the west. Dirty weather is coming on!"

"At any rate we have a favourable wind for reaching Cape Mandible," observed the reporter.

"A very fine wind," replied the sailor; "but we must tack to enter the gulf, and I should like to see my way clear in these unknown quarters."

"Quarters which appear to be filled with rocks," added Herbert, "if we judge by what we saw on the south coast of Shark Gulf."

"Pencroft," said Cyrus Harding, "do as you think best, we will leave it to you."

"Don't make your mind uneasy, captain," replied the sailor, "I shall not expose myself needlessly! I would rather a knife were run into my ribs than a sharp rock into those of my Bonadventure!"

That which Pencroft called ribs was the part of his vessel under water, and he valued it more than his own skin.

"What o'clock is it?" asked Pencroft.

"Ten o'clock," replied Gideon Spilett.

"And what distance is it to the Cape, captain?"

"About fifteen miles," replied the engineer.

"That's a matter of two hours and a half," said the sailor, "and we shall be off the Cape between twelve and one o'clock. Unluckily, the tide will be turning at that moment, and will be ebbing out of the gulf. I am afraid that it will be very difficult to get in, having both wind and tide against us."

"And the more so that it is a full moon to-day," remarked Herbert, "and these April tides are very strong."

"Well, Pencroft," asked Cyrus Harding, "can you not anchor off the Cape?"

"Anchor near land, with bad weather coming on!" exclaimed the sailor. "What are you thinking of, captain? We should run aground to a certainty!"

"What will you do then?"

"I shall try to keep in the offing until the flood, that is to say, till about seven in the evening, and if there is still light enough I will try to enter the gulf; if not, we must stand off and on during the night, and we will enter to-morrow at sunrise."

"As I told you, Pencroft, we will leave it to you," answered Harding.

"Ah!" said Pencroft, "if there was only a light-house on the coast, it would be much more convenient for sailors."

"Yes," replied Herbert, "and this time we shall have no obliging engineer to light a fire to guide us into port!"

"Why, indeed, my dear Cyrus," said Spilett, "we have never thanked you for it, but frankly, without that fire we should never have been able to reach--"

"A fire?" asked Harding, much astonished at the reporter's words.

"We mean, captain," answered Pencroft, "that on board the Bonadventure we were very anxious during the few hours before our return, and we should have pa.s.sed to windward of the island, if it had not been for the precaution you took of lighting a fire in the night of the 19th of October, on Prospect Heights."

"Yes, yes! That was a lucky idea of mine!" replied the engineer.

"And this time," continued the sailor, "unless the idea occurs to Ayrton, there will be no one to do us that little service!"

"No! no one!" answered Cyrus Harding.

A few minutes after, finding himself alone in the bows of the vessel with the reporter, the engineer bent down and whispered,-- "If there is one thing certain in this world, Spilett, it is that I never lighted any fire during the night of the 19th of October, neither on Prospect Heights nor on any other part of the island!"

[Ill.u.s.tration: ANOTHER MYSTERY]

CHAPTER XX.

A Night at Sea -- Shark Gulf -- Confidences -- Preparations for Winter -- Forwardness of the bad Season -- Severe Cold -- Work in the Interior -- In six Months -- A photographic Negative -- Unexpected Incident.

Things happened as Pencroft had predicted, he being seldom mistaken in his prognostications. The wind rose, and from a fresh breeze it soon increased to a regular gale; that is to say, it acquired a speed of from forty to forty-five miles an hour, before which a ship in the open sea would have run under close-reefed topsails. Now, as it was nearly six o'clock when the Bonadventure reached the gulf, and as at that moment the tide turned, it was impossible to enter. They were therefore compelled to stand off, for even if he had wished to do so, Pencroft could not have gained the mouth of the Mercy. Hoisting the jib to the mainmast by way of a storm-sail, he hove to, putting the head of the vessel towards the land.

Fortunately, although the wind was strong, the sea, being sheltered by the land, did not run very high. They had then little to fear from the waves, which always endanger small craft. The Bonadventure would doubtlessly not have capsized, for she was well ballasted; but enormous ma.s.ses of water falling on the deck, might injure her, if her timbers could not sustain them. Pencroft, as a good sailor, was prepared for anything. Certainly, he had great confidence in his vessel, but nevertheless he awaited the return of day with some anxiety.

During the night, Cyrus Harding and Gideon Spilett had no opportunity for talking together, and yet the words p.r.o.nounced in the reporter's ear by the engineer were well worth being discussed, together with the mysterious influence which appeared to reign over Lincoln Island. Gideon Spilett did not cease from pondering over this new and inexplicable incident,--the appearance of a fire on the coast of the island. The fire had actually been seen! His companions, Herbert and Pencroft, had seen it with him! The fire had served to signalise the position of the island during that dark night, and they had not doubted that it was lighted by the engineer's hand; and here was Cyrus Harding expressly declaring that he had never done anything of the sort! Spilett resolved to recur to this incident as soon as the Bonadventure returned, and to urge Cyrus Harding to acquaint their companions with these strange facts. Perhaps it would be decided to make in common a complete investigation of every part of Lincoln Island.

However that might be, on this evening no fire was lighted on these yet unknown sh.o.r.es, which formed the entrance to the gulf, and the little vessel stood off during the night.

When the first streaks of dawn appeared in the western horizon, the wind, which had slightly fallen, shifted two points, and enabled Pencroft to enter the narrow gulf with greater ease. Towards seven o'clock in the morning, the Bonadventure, weathering the North Mandible Cape, entered the strait and glided on to the waters, so strangely enclosed in the frame of lava.

"Well," said Pencroft, "this bay would make admirable roads, in which a whole fleet could lie at their ease!"

"What is especially curious," observed Harding, "is that the gulf has been formed by two rivers of lava, thrown out by the volcano, and acc.u.mulated by successive eruptions. The result is that the gulf is completely sheltered on all sides, and I believe that even in the stormiest weather, the sea here must be as calm as a lake."

"No doubt," returned the sailor, "since the wind has only that narrow entrance between the two capes to get in by; and besides, the north cape protects that of the south in a way which would make the entrance of gusts very difficult. I declare our Bonadventure could stay here from one end of the year to the other, without even dragging at her anchor!"

"It is rather large for her!" observed the reporter.

"Well! Mr. Spilett," replied the sailor, "I agree that it is too large for the Bonadventure; but if the fleets of the Union were in want of a harbour in the Pacific, I don't think they would ever find a better place than this!"

"We are in the shark's mouth," remarked Neb, alluding to the form of the gulf.

"Right into its mouth, my honest Neb!" replied Herbert; "but you are not afraid that it will shut upon us, are you?"

"No, Mr. Herbert," answered Neb; "and yet this gulf here doesn't please me much! It has a wicked look!"

"Hallo!" cried Pencroft, "here is Neb turning up his nose at my gulf, just as I was thinking of presenting it to America!"

"But, at any rate, is the water deep enough?" asked the engineer, "for a depth sufficient for the keel of the Bonadventure, would not be enough for those of our iron-clads."

"That is easily found out," replied Pencroft.

And the sailor sounded with a long cord, which served him as a lead-line, and to which was fastened a lump of iron. This cord measured nearly fifty fathoms, and its entire length was unrolled without finding any bottom.

"There," exclaimed Pencroft, "our iron-clads can come here after all! They would not run aground!"

"Indeed," said Gideon Spilett, "this gulf is a regular abyss; but, taking into consideration the volcanic origin of the island, it is not astonishing that the sea should offer similar depressions."

"One would say too," observed Herbert, "that these cliffs were perfectly perpendicular; and I believe that at their foot, even with a line five or six times longer, Pencroft would not find the bottom."

"That is all very well," then said the reporter; "but I must point out to Pencroft that his harbour is wanting in one very important respect!"

"And what is that, Mr. Spilett?"

"An opening, a cutting of some sort, to give access to the interior of the island. I do not see a spot on which we could land."

And, in fact, the steep lava cliffs did not afford a single place suitable for landing. They formed an insuperable barrier, recalling, but with more wildness, the fiords of Norway. The Bonadventure, coasting as close as possible along the cliffs, did not discover even a projection which would allow the pa.s.sengers to leave the deck.

Pencroft consoled himself by saying that with the help of a mine they could soon open out the cliff when that was necessary, and then, as there was evidently nothing to be done in the gulf, he steered his vessel towards the strait and pa.s.sed out at about two o'clock in the afternoon.
