The next day, the 18th of February, was devoted to the exploration of all that wooded region forming the shore from Reptile End to Falls River. The colonists were able to search this forest thoroughly, for, as it was comprised between the two shores of the Serpentine Peninsula, it was only from three to four miles in breadth. The trees, both by their height and their thick foliage, bore witness to the vegetative power of the soil, more astonishing here than in any other part of the island. One might have said that a corner from the virgin forests of America or Africa had been transported into this temperate zone. This led them to conclude that the superb vegetation found a heat in this soil, damp in its upper layer, but warmed in the interior by volcanic fires, which could not belong to a temperate climate. The most frequently occurring trees were knaries and eucalypti of gigantic dimensions.
But the colonists' object was not simply to admire the magnificent vegetation. They knew already that in this respect Lincoln Island would have been worthy to take the first rank in the Canary group, to which the first name given was that of the Happy Isles. Now, alas! their island no longer belonged to them entirely; others had taken possession of it, miscreants polluted its shores, and they must be destroyed to the last man.
No traces were found on the western coast, although they were carefully sought for. No more footprints, no more broken branches, no more deserted camps.
"This does not surprise me," said Cyrus Harding to his companions. "The convicts first landed on the island in the neighborhood of Flotsam Point, and they immediately plunged into the Far West forests, after crossing Tadorn Marsh. They then followed almost the same route that we took on leaving Granite House. This explains the traces we found in the wood. But, arriving on the shore, the convicts saw at once that they would discover no suitable retreat there, and it was then that, going northwards again, they came upon the corral."
"Where they have perhaps returned," said Pencroft.
"I do not think so," answered the engineer, "for they would naturally suppose that our researches would be in that direction. The corral is only a storehouse to them, and not a definitive encampment."
"I am of Cyrus' opinion," said the reporter, "and I think that it is among the spurs of Mount Franklin that the convicts will have made their lair."
"Then, captain, straight to the corral!" cried Pencroft. "We must finish them off, and till now we have only lost time!"
"No, my friend," replied the engineer; "you forget that we have a reason for wishing to know if the forests of the Far West do not contain some habitation. Our exploration has a double object, Pencroft. If, on the one hand, we have to chastise crime, we have, on the other, an act of gratitude to perform."
"That was well said, captain," replied the sailor, "but, all the same, it is my opinion that we shall not find the gentleman until he pleases."
And truly Pencroft only expressed the opinion of all. It was probable that the stranger's retreat was not less mysterious than was he himself.
That evening the cart halted at the mouth of Falls River. The camp was organized as usual, and the customary precautions were taken for the night. Herbert, become again the healthy and vigorous lad he was before his illness, derived great benefit from this life in the open air, between the sea breezes and the vivifying air from the forests. His place was no longer in the cart, but at the head of the troop.
The next day, the 19th of February, the colonists, leaving the shore, where, beyond the mouth, basalts of every shape were so picturesquely piled up, ascended the river by its left bank. The road had been already partly cleared in their former excursions made from the corral to the west coast. The settlers were now about six miles from Mount Franklin.
The engineer's plan was this:--To minutely survey the valley forming the bed of the river, and to cautiously approach the neighborhood of the corral; if the corral was occupied, to seize it by force; if it was not, to entrench themselves there and make it the center of the operations which had for their object the exploration of Mount Franklin.
This plan was unanimously approved by the colonists, for they were impatient to regain entire possession of their island.
They made their way then along the narrow valley separating two of the largest spurs of Mount Franklin. The trees, crowded on the river's bank, became rare on the upper slopes of the mountain. The ground was hilly and rough, very suitable for ambushes, and over which they did not venture without extreme precaution. Top and Jup skirmished on the flanks, springing right and left through the thick brushwood, and emulating each other in intelligence and activity. But nothing showed that the banks of the stream had been recently frequented--nothing announced either the presence or the proximity of the convicts. Towards five in the evening the cart stopped nearly 600 feet from the palisade. A semicircular screen of trees still hid it.
It was necessary to reconnoiter the corral, in order to ascertain if it was occupied. To go there openly, in broad daylight, when the convicts were probably in ambush, would be to expose themselves, as poor Herbert had done, to the firearms of the ruffians. It was better, then, to wait until night came on.
However, Gideon Spilett wished without further delay to reconnoiter the approaches to the corral, and Pencroft, who was quite out of patience, volunteered to accompany him.
"No, my friends," said the engineer, "wait till night. I will not allow one of you to expose himself in open day."
"But, captain--" answered the sailor, little disposed to obey.
"I beg of you, Pencroft," said the engineer.
"Very well!" replied the sailor, who vented his anger in another way, by bestowing on the convicts the worst names in his maritime vocabulary.
The colonists remained, therefore, near the cart, and carefully watched the neighboring parts of the forest.
Three hours passed thus. The wind had fallen, and absolute silence reigned under the great trees. The snapping of the smallest twig, a footstep on the dry leaves, the gliding of a body among the grass, would have been heard without difficulty. All was quiet. Besides, Top, lying on the grass, his head stretched out on his paws, gave no sign of uneasiness. At eight o'clock the day appeared far enough advanced for the reconnaissance to be made under favorable conditions. Gideon Spilett declared himself ready to set out accompanied by Pencroft. Cyrus Harding consented. Top and Jup were to remain with the engineer, Herbert, and Neb, for a bark or a cry at a wrong moment would give the alarm.
"Do not be imprudent," said Harding to the reporter and Pencroft, "you have not to gain possession of the corral, but only to find out whether it is occupied or not."
"All right," answered Pencroft.
And the two departed.
Under the trees, thanks to the thickness of their foliage, the obscurity rendered any object invisible beyond a radius of from thirty to forty feet. The reporter and Pencroft, halting at any suspicious sound, advanced with great caution.
They walked a little distance apart from each other so as to offer a less mark for a shot. And, to tell the truth, they expected every moment to hear a report. Five minutes after leaving the cart, Gideon Spilett and Pencroft arrived at the edge of the wood before the clearing beyond which rose the palisade.
They stopped. A few straggling beams still fell on the field clear of trees. Thirty feet distant was the gate of the corral, which appeared to be closed. This thirty feet, which it was necessary to cross from the wood to the palisade, constituted the dangerous zone, to borrow a ballistic term: in fact, one or more bullets fired from behind the palisade might knock over any one who ventured on to this zone. Gideon Spilett and the sailor were not men to draw back, but they knew that any imprudence on their part, of which they would be the first victims, would fall afterwards on their companions. If they themselves were killed, what would become of Harding, Neb, and Herbert?
But Pencroft, excited at feeling himself so near the corral where he supposed the convicts had taken refuge, was about to press forward, when the reporter held him back with a grasp of iron.
"In a few minutes it will be quite dark," whispered Spilett in the sailor's ear, "then will be the time to act."
