The exact position of the encampment could be determined by the bearing of Mount Franklin, and as the volcano arose in the north at a distance of less than three miles, they had only to go straight towards the south-west to reach the western coast. They set out, having first carefully secured the canoe. Pencroft and Neb carried sufficient provisions for the little band for at least two days. It would not thus be necessary to hunt. The engineer advised his companions to refrain from firing, that their presence might not be betrayed to any one near the shore. The first hatchet blows were given among the brushwood in the midst of some mastick-trees, a little above the cascade; and his compass in his hand, Cyrus Harding led the way. The forest here was composed for the most part of trees which had already been met with near the lake and on Prospect Heights. There were deodars, Douglas firs, casuarinas, gum-trees, eucalypti, hibiscus, cedars, and other trees, generally of a moderate size, for their number prevented their growth. Since their departure, the settlers had descended the slopes which constituted the mountain system of the island, on to a dry soil, but the luxuriant vegetation of which indicated it to be watered either by some subterranean marsh or by some stream. However, Cyrus Harding did not remember to have seen, at the time of his excursion to the crater, any other watercourses but the Red Creek and the Mercy. During the first part of their excursion, they saw numerous troops of monkeys who exhibited great astonishment at the sight of men, whose appearance was so new to them. Gideon Spilett jokingly asked whether these active and merry quadrupeds did not consider him and his companions as degenerate brothers. And certainly, pedestrians, hindered at each step by bushes, caught by creepers, barred by trunks of trees, did not shine beside those supple animals, who, bounding from branch to branch, were hindered by nothing on their course. The monkeys were numerous, but happily they did not manifest any hostile disposition. Several pigs, agoutis, kangaroos, and other rodents were seen, also two or three kaolas, at which Pencroft longed to have a shot. "But," said he, "you may jump and play just now; we shall have one or two words to say to you on our way back!" At half-past nine the way was suddenly found to be barred by an unknown stream, from thirty to forty feet broad, whose rapid current dashed foaming over the numerous rocks which interrupted its course. This creek was deep and clear, but it was absolutely unnavigable. "We are cut off!" cried Neb. "No," replied Herbert, "it is only a stream, and we can easily swim over." "What would be the use of that?" returned Harding. "This creek evidently runs to the sea. Let us remain on this side and follow the bank, and I shall be much astonished if it does not lead us very quickly to the coast. Forward!"
