We saw no more of them that day, or the next, but on the second day, in the afternoon, when Billy got on the boulder to take a look round, he called to me that he spied a raft coming towards us from the direction of the cave, with Hoggett and half-a-dozen more aboard. I could see that Billy was a little alarmed at this, for he always had a great dread of Hoggett; but I told him not to be disturbed, for I was sure from our vantage ground, and with our bows and arrows, we could easily beat them off if they landed and tried to clamber up. "Things are going well," I said to him. "They have actually begun to work at last, and pretty diligently, too, to make that raft in less than two days." "But what's the odds to us, master," says Billy, "if they have begun to work? I think it's a very bad sign, I do." "We shall see," I said; and Billy looked very much puzzled, for I had not told him my design in its fulness, because I wished to get a certain assurance of its success first. [Sidenote: Invasion Fails] It was soon plain that we should not be put to the trouble of defence, and we had a hearty laugh at the coil in which the men soon found themselves; for coming pretty close to the shore, they were caught in the current which ran very swiftly through the narrow gap, and despite the desperate efforts which they made with their paddles, the raft, which is at all times a clumsy vessel, was swept along and twirled this way and that, and the men were in such extremity of danger that they ceased to gaze at us, and bent all their energies to prevent the raft from being dashed against the rocks on either side and shivered to atoms. They were carried right through the channel, and pretty nearly to the natural archway, before they got the least control over the raft, and even then they could only manage it enough to steer clear of the sides of the arch, and so win to the open sea. By that time the current had lost the most of its force, and we knew very well that if they paddled out to the left, and made a sufficiently large circuit, they might gain the north side of Red Rock, even with so clumsy a vessel as theirs, and discover our landing-place. However, they had been so greatly discomfited that I was not much surprised when, instead of steering to the left, they allowed the raft to drift past the promontory, and after a little while they disappeared from our sight, having clearly determined to return to the place where they had embarked.
