It was somewhat late that night when I turned in, as I had slept well all through the previous night and did not feel tired; and even when I had bestowed myself for the night I did not get to sleep for some time, for I felt that we must by this time be drawing close in to the coast; and supposing we should fall in with a man-o'-war, how was I to communicate with her if this man was going to keep me cooped up down below?  True, I might succeed in attracting the attention of those on board such a ship by waving my handkerchief out of my cabin port if we happened to pass her closely enough for such a signal to be seen, and if she happened also to be on the starboard side, which was the side on which my berth was situated; but I was very strongly of opinion that, after what had happened, Williams would take especial care to give an exceedingly wide berth to any men-o'-war that he might happen to sight.
