All next day the horizon on every side was clear of a single speck; no signs either of ship or schooner, till I began to wish we were out of it, hoping the Seringapatam had, after all, kept the old course for Bombay, in spite of us. I found Jones had warned the men not to get our water out of the tank; it being poisoned in a way fit to last for years, as the pirates knew how to do. For our parts, we had to amuse ourselves the best way we could, waiting for the schooner to come down again for us, which was the only thing I looked for now. That night the white appearance of the water to north and windward seemed a good deal gone, save where it hung like a haze in the direction it took off the island: the stars shone out, and in two or three nights more I found from Jones there would be nothing of it, which I hoped I should have to take on his word. At daybreak, however, our look-out could all of a sudden be seen hoisting the signal for a sail in sight, and waving his hat for us to come. No sooner had we hurried up, accordingly, than a sail could be made out in the south-east, hull down; and the schooner not being likely thereaway, a certain flutter in me at once set it down for the Indiaman at last, on her way far past the island for the open channel. Being broad daylight, too, with a fresh breeze blowing, we saw that Foster and his party, if they carried out their scheme, would have to wait till she was a long way to windward at night-time, in order to get clear off. In fact, I had every one kept down off the height, lest the ship's glasses might possibly notice something; while, at the same time, we hadn't even a fire kindled to cook our victuals. I was watching her over the brow of the hill, through the telescope, when she evidently stood round on the other tack to get up to windward, which brought her gradually nearer. She was a large ship, under full canvass; and at last she rose her hull to the white streak below the bulwarks, till I began to think they intended passing the island to eastward to make the channel. I went down for Jones, and asked him how far the reefs actually ran out, when he told me there would probably be signs enough of them in such a strong, breeze; besides, as he reminded me, if she was the Indiaman, it was the captain himself that had a chart of them; in which, from the particular nature of it--being an old buccaneering chart, as he thought--they would be laid down quite plainly. Indeed, when we both returned to the height, there were lines of surf to be noticed here and there, more than three miles out; and seeing her by that time so distinctly, a new uneasiness began to enter my head. There were no signals we could make, even if they didn't serve the other way; and, to tell the truth, I didn't much like the idea of being found there. Still, it was terrible to see her getting nearer and nearer, without the power of doing the least thing to warn her
