That evening I took my supper along with the passengers, as I had been used to do, for I wished to appear unconcerned, as, after all, my suspicions might be altogether groundless. Nevertheless, I came upon deck again as soon as I was able, and found that the stranger was now so far come into sight as to show a part of her hull, which was low, and painted black, and was of such an appearance as rather to increase than to lessen my serious suspicions of her nature.
I could see there were two whale-boats ahead of her, and it was very plain to me that it was by means of these that the bark was making head against the current. At first I was more than ever amazed at this, seeing that the current at that point could not run at less than the rate of two or three knots an hour, against which two boats could not hope to tow a craft of her size without some contrivance to aid their efforts. Every now and then I could hear the clicking of the capstan, as though the vessel was heaving anchor, and led by this sound, I after a while perceived how she was making way, though if I had not seen the same plan used in the Strait of Malacca by the City of Worcester, when I was there in the year '17, I much misdoubt whether I could have so readily discovered the design which they were in this instance using. As it was, I was not long in finding out what they were about.
The two boats ahead of the strange craft were towing a square sail through the water by a line fastened to the middle of the same. From all four corners of this sail ran good stout ropes, which were made fast to the anchor cable of the bark. The two boats might tow this square through the water easily enough by that one line fastened to the middle, because the sail would then close and so slip easily through the water; but so soon as the bark began to haul upon it from all four corners it spread out as though filled with wind, and so offered a vast resistance to the water. By this contrivance the bark was making headway at about the rate of a knot an hour against the current, so that by seven o'clock she was clear out beyond the cape and into the open water beyond.
At that time the sun had not yet gone down, and the distant vessel stood out against the reddish-gray sky to the eastward, with all the cordage and the masts as sharp as so many hairs and straws in the red light of the setting sun.
I was standing just under the poop-deck at the time, with the glass to my eye, when, of a sudden, I saw something black begin rising from the deck to the fore. There was not enough breeze going to spread it, but I knew as well as anything in all of my life that it was the "Black Roger," and that the white that I could see among the folds was the wicked sign of the "skull and crossbones," which those bloody and cruel wretches are pleased to adopt as the ensign of their trade. Nor were we long in doubt as to their design, for even as I watched I saw a sudden puff of white smoke go up from her side and hang motionlessly in the still air, whilst a second or two later sounded the dull and heavy boom of the distant cannon, and a round shot came skipping across the water from wave to wave, though too far away and with too poor aim to do any damage from that distance, which could not have been less than two miles.
"What does that mean, captain?" said Mistress Pamela, who stood with the other passengers observing the bark from the poop-deck above.
"A salute, madam," said I, and so shut my glass and went into my cabin, where Mr. Langely presently joined me at my request, and where we talked over this very ugly piece of business at our leisure.

In those hot latitudes, such as Madagascar, the darkness cometh very sudden after sunset, and with no long twilights such as we have in England, so that within half an hour after the pirate had saluted us with a round shot, as told above, it had passed from daylight to night-time, and there being no moon until about four o'clock in the morning, it was very dark, with an infinite quantity of stars shining most beautifully in the sky.
