Harding did not hesitate to give utterance to the suggestions which this fact, at once surprising and unexpected, could not fail to raise in his mind. He took the bullet, turned it over and over, rolled it between his finger and thumb; then, turning to Pencroft, he asked—
"Are you sure that the peccary wounded by this bullet was not more than three months old?"
"Not more, captain," replied Pencroft. "It was still sucking its mother when I found it in the trap."
"Well," said the engineer, "that proves that within three months a gun-shot was fired in Lincoln Island."
"And that a bullet," added Gideon Spilett, "wounded, though not mortally, this little animal."
"That is unquestionable," said Cyrus Harding, "and these are the deductions which must be drawn from this incident: that the island was inhabited before our arrival, or that men have landed here within three months. Did these men arrive here voluntarily or involuntarily, by disembarking on the shore or by being wrecked? This point can only be cleared up later. As to what they were, Europeans or Malays, enemies or friends of our race, we cannot possibly guess; and if they still inhabit the island, or if they have left it, we know not. But these questions are of too much importance to be allowed to remain long unsettled."
"No! a hundred times no! a thousand times no!" cried the sailor, springing up from the table. "There are no other men than ourselves on Lincoln Island! By my faith! The island isn't large, and if it had been inhabited, we should have seen some of the inhabitants long before this!"
"In fact, the contrary would be very astonishing," said Herbert.
"But it would be much more astonishing, I should think," observed the reporter, "that this peccary should have been born with a bullet in its inside!"
"At least," said Neb seriously, "if Pencroft has not had—"
"Look here, Neb," burst out Pencroft. "Do you think I could have a bullet in my jaw for five or six months without finding it out? Where could it be hidden?" he asked opening his mouth to show the two-and-thirty teeth with which it was furnished. "Look well, Neb, and if you find one hollow tooth in this set, I will let you pull out half a dozen!"
"Neb's supposition is certainly inadmissible," replied Harding, who, notwithstanding the gravity of his thoughts, could not restrain a smile. "It is certain that a gun has been fired in the island, within three months at most. But I am inclined to think that the people who landed on this coast were only here a very short time ago, or that they just touched here; for if, when we surveyed the island from the summit of Mount Franklin, it had been inhabited, we should have seen them or we should have been seen ourselves. It is therefore probable that within only a few weeks castaways have been thrown by a storm on some part of the coast. However that may be, it is of consequence to us to have this point settled."
"I think that we should act with caution," said the reporter.
"Such is my advice," replied Cyrus Harding, "for it is to be feared that Malay pirates have landed on the island!"
"Captain," asked the sailor, "would it not be a good plan, before setting out, to build a canoe in which we could either ascend the river, or, if we liked, coast round the island? It will not do to be unprovided."
"Your idea is good, Pencroft," replied the engineer, "but we cannot wait for that. It would take at least a month to build a boat."
"Yes, a real boat," replied the sailor; "but we do not want one for a sea voyage, and in five days at the most, I will undertake to construct a canoe fit to navigate the Mercy."
"Five days," cried Neb, "to build a boat?"
"Yes, Neb; a boat in the Indian fashion."
"Of wood?" asked the negro, looking still unconvinced.
"Of wood," replied Pencroft, "or rather of bark. I repeat, captain, that in five days the work will be finished!"
"In five days, then, be it," replied the engineer.
"But till that time we must be very watchful," said Herbert.
"Very watchful indeed, my friends," replied Harding; "and I beg you to confine your hunting excursions to the neighbourhood of Granite House."
The dinner ended less gaily than Pencroft had hoped.
So, then, the island was, or had been, inhabited by others than the settlers. Proved as it was by the incident of the bullet, it was hereafter an unquestionable fact, and such a discovery could not but cause great uneasiness amongst the colonists.
Cyrus Harding and Gideon Spilett, before sleeping, conversed long about the matter. They asked themselves if by chance this incident might not have some connection with the inexplicable way in which the engineer had been saved, and the other peculiar circumstances which had struck them at different times. However Cyrus Harding, after having discussed the pros and cons of the question, ended by saying—
"In short, would you like to know my opinion, my dear Spilett?"
"Yes, Cyrus."
"Well, then, it is this: however minutely we explore the island, we shall find nothing."
The next day Pencroft set to work. He did not mean to build a boat with boards and planking, but simply a flat-bottomed canoe, which would be well suited for navigating the Mercy—above all, for approaching its source, where the water would naturally be shallow. Pieces of bark, fastened one to the other, would form a light boat; and in case of natural obstacles, which would render a portage necessary, it would be easily carried. Pencroft intended to secure the pieces of bark by means of nails, to insure the canoe being water-tight.
It was first necessary to select the trees which would afford a strong and supple bark for the work. Now the last storm had brought down a number of large birch trees, the bark of which would be perfectly suited for their purpose. Some of these trees lay on the ground, and they had only to be barked, which was the most difficult thing of all, owing to the imperfect tools which the settlers possessed. However, they overcame all difficulties.
Whilst the sailor, seconded by the engineer, thus occupied himself without losing an hour, Gideon Spilett and Herbert were not idle. They were made purveyors to the colony. The reporter could not but admire the boy, who had acquired great skill in handling the bow and spear. Herbert also showed great courage and much of that presence of mind which may justly be called "the reasoning of bravery." These two companions of the chase, remembering Cyrus Harding's recommendations, did not go beyond a radius of two miles round Granite House; but the borders of the forest furnished a sufficient tribute of agouties, capybaras, kangaroos, peccaries, etc.; and if the result from the traps was less than during the cold, still the warren yielded its accustomed quota, which might have fed all the colony in Lincoln Island.
Often during these excursions, Herbert talked with Gideon Spilett on the incident of the bullet, and the deductions which the engineer drew from it, and one day—it was the 26th of October—he said—
"But, Mr. Spilett, do you not think it very extraordinary that, if any castaways have landed on the island, they have not yet shown themselves near Granite House?"
"Very astonishing if they are still here," replied the reporter, "but not astonishing at all if they are here no longer!"
"So you think that these people have already quitted the island?" returned Herbert.
"It is more than probable, my boy; for if their stay was prolonged, and above all, if they were still here, some accident would have at last betrayed their presence."
"But if they were able to go away," observed the lad, "they could not have been castaways."
"No, Herbert; or, at least, they were what might be called provisional castaways. It is very possible that a storm may have driven them to the island without destroying their vessel, and that, the storm over, they went away again."
"I must acknowledge one thing," said Herbert, "it is that Captain Harding appears rather to fear than desire
