Thinking thus, and worrying myself as to the best course to be pursued in certain eventualities, I lay there restlessly tossing first to one side, then to the other, until at length, sitting up in my bunk and putting my face to the open port in quest of a breath of fresh air, the fancy took me that the darkness was no longer quite so opaque as it had been, nay, I was sure of it, for by putting my face right up against the circular opening I was enabled to catch an occasional transient gleam of faint, shifting light that I knew was the glancing of the coming dawn upon the back of the oily swell that came creeping up to the ship; while, by directing my glances higher, I found that I was able to make out indistinctly something of the outline of the great black cloud- masses that overhung us. In those latitudes the dawn comes as quickly as the daylight vanishes, day comes and goes with a rush--thus within five minutes of the time when I first glanced out through the port there was enough light abroad to reveal a louring, overcast, thunder-threatening sky, an inky, oil- smooth, sluggishly undulating sea, and a long, low schooner with tremendously taunt masts raking over her stern, and not an inch of canvas set, lying broadside-on to us at a distance of some two miles to the eastward. When I caught my first glimpse of her she was very little more than a black blur standing out against the background of scarcely less black sky; but even as I sat looking at her the light grew, her outline sharpened and became clear and distinct, and my heart gave a great bound of delight as the conviction forced itself upon me that I knew her. Yes, that long low hull, with its abnormal length of counter, and its bold sheer forward, the high, dominating bow with its excessive rake of stem, and the peculiar steeve of the bowsprit were all familiar to me. I had seen and noted them before while in Sierra Leone harbour, and I was convinced that the craft was none other than the British man- o'-war schooner _Gadfly_, armed with eight 12-pound carronades and a long 32-pound pivot-gun on her forecastle, with a crew of eighty men under the command of Lieutenant Peters, than whom there was not a more dashing and enterprising officer on the Coast. I had just arrived at the above conclusion when I heard one of the barque's crew hailing the poop; I could not distinguish what was said, but I presumed that it had reference to the schooner, for immediately upon the hail I heard the creaking of the basket-chair on the poop, as though Marcel was just hoisting himself out of it, and presently his reply came floating down through the skylight, "Ay, ay; I see her." Then I heard the soft shuffling of his footsteps overhead and guessed that he was getting hold of the telescope wherewith to examine the schooner.
