However, when we met, Billy told me that from the hill-top he had seen a fleet of canoes on the north side of the island, passing from west to east. They were filled with savages, though whether armed or not he could not tell, they being a good distance out at sea, nor was there anything to show whether they purposed landing. It came into my mind with a shock at that moment that we were very ill able to defend ourselves in case they should land and attack us, for we had very little provision in our hut, and if we took refuge there they might keep us shut up until we died of hunger, or thirst, which would be worse. I blamed myself very much for lack of prudence in not making provision for such an emergency, but the truth is that after spending so many months without seeing a human form we had become careless, and went from day to day as though there had been no human beings in the world except our two selves. However, it was too late to make up for this neglect now, if the savages did indeed land, and I saw that in that case we could only take to the woods and trust that our hut and plantations, being inland, might pass undiscovered. Accordingly I accompanied Billy back up the hill, and we went round the wood where our signal-tree was, to a place nearer the crater, whence we had a more extensive view. "There they are!" cried Billy, pointing out to sea, and I saw eight or nine long canoes filled with brown men, who must have numbered near two hundred in all. But I saw with inexpressible relief that they had come past the Red Rock, and were proceeding steadily eastward, and knowing that there was no beach on the north side of the island where they might land, we had great hope that we should not be troubled with them. Keeping out of sight behind rocks, though indeed there was perhaps little danger of our being seen, we watched the fleet until it became no more than a speck on the eastern horizon, and then we went down to our hut, relieved of present danger, but by no means easy in mind about the future.
