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 masses 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 pronounced 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 signalize 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 shores, 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 accumulated 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 harbor in the Pacific, I don't think they would ever find a better place than this!"
"We are in the shark's mouth," remarked Nab, alluding to the form of the gulf.
"Right into its mouth, my honest Nab!" 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 bottom."
"That is all very well," then said the reporter, "but I must point out to Pencroft that his harbor 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 passengers 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 passed out at about two o'clock in the afternoon.
"Ah!" said Nab, uttering a sigh of satisfaction.
One might really say that the honest Negro did not feel at his ease in those enormous jaws.
The distance from Mandible Cape to the mouth of the Mercy was not more than eight miles. The head of the "Bonadventure" was put towards Granite House, and a fair wind filling her sails, she ran rapidly along the coast.
To the enormous lava rocks succeeded soon those capricious sand dunes, among which the engineer had been so singularly recovered, and which seabirds frequented in thousands.
About four o'clock, Pencroft leaving the point of the islet on his left, entered the channel which separated it from the coast, and at five o'clock the anchor of the "Bonadventure" was buried in the sand at the mouth of the Mercy.
The colonists had been absent three days from their dwelling. Ayrton was waiting for them on the beach, and Jup came joyously to meet them, giving vent to deep grunts of satisfaction.
A complete exploration of the coast of the island had now been made, and no suspicious appearances had been observed. If any mysterious being resided on it, it could only be under cover of the impenetrable forest of the Serpentine Peninsula, to which the colonists had not yet directed their investigations.
Gideon Spilett discussed these things with the engineer, and it was agreed that they should direct the attention of their companions to the strange character of certain incidents which had occurred on the island, and of which the last was the most unaccountable.
However, Harding, returning to the fact of a fire having been kindled on the shore by an unknown hand, could not refrain from repeating for the twentieth time to the reporter,--
"But are you quite sure of having seen it? Was it not a partial eruption of the volcano, or perhaps some meteor?"
"No, Cyrus," answered the reporter, "it was certainly a fire lighted by the hand of man. Besides; question Pencroft and Herbert. They saw it as I saw it myself, and they will confirm my words."
In consequence, therefore, a few days after, on the 25th of April, in the evening, when the settlers were all collected on Prospect Heights, Cyrus Harding began by saying,--
"My friends, I think it my duty to call your attention to certain incidents which have occurred in the island, on the subject of which I shall be happy to have your advice. These incidents are, so to speak, supernatural--"
"Supernatural!" exclaimed the sailor, emitting a volume of smoke from his mouth. "Can it be possible that our island is supernatural?"
"No, Pencroft, but mysterious, most certainly," replied the engineer; "unless you can explain that which Spilett and I have until now failed to understand."
"Speak away, captain," answered the sailor.
"Well, have you understood," then said the engineer, "how was it that after falling into the sea, I was found a quarter of a mile into the interior of the island, and that, without my having any consciousness of my removal there?"
"Unless, being unconscious--" said Pencroft.
"That is not admissible," replied the engineer. "But to continue. Have you understood how Top was able to discover your retreat five miles from the cave in which I was lying?"
"The dog's instinct--" observed Herbert.
"Singular instinct!" returned the reporter, "since notwithstanding the storm of rain and wind which was raging during that night, Top arrived at the Chimneys, dry and without a speck of mud!"
"Let us continue," resumed the engineer. "Have you understood how our dog was so strangely thrown up out of the water of the lake, after his struggle with the dugong?"
"No! I confess, not at all," replied Pencroft, "and the wound which the dugong had in its side, a wound which seemed to have been made with a sharp instrument; that can't be understood, either."
"Let us continue again," said Harding. "Have you understood, my friends, how that bullet got into the body of the young peccary; how that case happened to be so fortunately stranded, without there being an............
