The nature of the ground had led us somewhat out of the course for the house. We now struck across the country, hoping to reach it, the ground being less covered with trees and underwood. We had gone for some distance, when we saw before us a high mound. It could not be called a mountain, but it was of considerable elevation, and of a conical shape, with a flat top. My uncle believed that it had been formed by volcanic action, though now being covered with brushwood and herbage and a few tall trees, it was evident that it had been thrown up some time. We climbed to the top of it, expecting to find a view of the sea beyond; but the trees which clothed the base were too lofty to allow us to see to any great distance. Here and there, however, there was a small gap, through which we caught a glimpse of the ocean.

“This would make a fine place for a fort, if any of those pirate fellows come this way,” observed Dick Tarbox as I was standing near him. “I would undertake to fortify it against all comers, if we had a little time to make ready. I have seen some work of that sort in my younger days, when I served aboard a man-of-war; and it would require daring fellows to get inside such a place as we could make it, if we defended it with the spirit which I know we should. Why, bless you, Walter, the young ladies and the old Frau would load our muskets for us, and we might blaze away till we had picked off every Malay who might attempt to get up the hill.”

“But why do you think pirates are likely to come here?” I asked.

“As to that, they are cruising about in these seas, and are as likely to come here as to any other place, if they think they can get anything by coming. Your uncle did wisely to build his house in the forest out of sight, or he would have been carried off long ago; and as they have not been here for some time, it is the more likely that they will come soon.”

There was a hollow in the centre of the cone which had probably formed the mouth of the old volcano, if volcano it had been, thus making a rim or bank all the way round; and on the top of this Tarbox proposed erecting palisades, and a stage, from which we might fire. By making hollows in the earth where we might store our goods and provisions, and where the ladies might remain free from the risk of shot, our fort would be perfect. My uncle overheard our conversation. “I hope there is little risk of such an event,” he observed carelessly. The wood below us was so thick, that it seemed scarcely possible we could penetrate it. However, we were compelled to get there some way or other, or we should have had to go back the way we had come. While hunting about, we found what appeared to be the bed of a stream, though perfectly dry. My uncle, on examining it, said he was sure it led in the direction we wished to go. After proceeding a little way, we found that it was entirely free of trees or shrubs. The bottom was covered with stones, rounded by the once boiling torrent which poured down from the high ground during the rainy season. They were, however, not spheres, but disk-shaped fragments of slate, very thin, the sharp corners rounded off by the water. Here and there, too, we found boulders of opaque, milk-white quartz. Generally the bed was level, but occasionally there were holes where the torrent had been wont to rest in its course towards the ocean. We proceeded along it at a far more rapid rate than we had hitherto been able to move. The shadows which came across our path had been growing longer and longer, when my uncle recognised some trees which grew in the neighbourhood of the house. We had once more to use our axes, and by exerting them actively, we cut our way through to the path which he had formed. It was almost dusk when we saw the high pointed roof of the house before us. Our shouts brought out the inmates, the Frau leading the way, though not accustomed to running. She clasped Emily and Grace in her arms, bursting into tears when she saw them.

“Oh! so glad you come back!” she exclaimed. “We so frightened that you have been carried away by de pirates!”

What she could mean we could scarcely understand, nor was Tanda at first very explicit. Mr Hooker, however, after our greetings were over, told us that as Tanda had been on the sea-shore, collecting shell-fish as a variety to their repast, he had seen, at no great distance from the land, several prows, which, from their build and general appearance, he was sure were those of Sooloo rovers, or perhaps pirates from the coast of Borneo. He had just arrived with the alarming intelligence, and he was afraid they were coming to land on the island. The fading light would scarcely enable us to discover them, for though a few minutes before it had been broad daylight, darkness comes on so rapidly in that latitude, that day, as it were, leaps into night in the course of a few minutes. We hurried down, however, to the beach; but when we got there, we could only distinguish in the far distance some shadowy forms, which might have been the piratical vessels. Which way they were steering, however, the most practised eyes among us could not discover, and directly afterwards they were totally hid from sight. We returned to the house to consult what was to be done.

“If you would take my advice, gentlemen,” said Mr Thudicumb, “you will have provisions done up, and arms and ammunition ready for a quick march, and anything else that you consider most valuable to carry away. We will then station a look-out down on the beach, or at the end of Flagstaff Rock, to give us early notice of the approach of the enemy. If they come, they are pretty sure to find this house out; and, if they get hold of us, to knock us on the head or cut our throats. As, however, you have explored the interior of the country, we shall know in what direction to go, and we shall be able to have the start of them, and may therefore get away into a safe place, where they cannot find us. Probably they will be content with such booty as they can find here—though there is not much to their taste—and will, after a time, take themselves off.”

Mr Thudicumb’s advice was considered good, and my uncle and Mr Hooker agreed to adopt it.

“If they do come, though, what a grievous pity it would be to have all our collection destroyed,” said Mr Hooker. “Is there no place where we can stow them in safety?”
