Presently, with the heat, and the sun beating right down on to me, I grew thirsty; and, for want of something better, I pulled out a bit of plug I had on me, and bit off a chew; though, as a rule, it is not a habit of mine. After a little, naturally enough, I glanced round for the spittoon; but discovered that it was not there. Probably it had been taken forrard when the decks were washed, to give it a scrub. So, as there was no one on the poop, I left the wheel, and stepped aft to the taffrail. It was thus that I came to see something altogether unthought of--a full-rigged ship, close-hauled on the port tack, a few hundred yards on our starboard quarter. Her sails were scarcely filled by the light breeze, and flapped as she lifted to the swell of the sea. She appeared to have very little way through the water, certainly not more than a knot an hour. Away aft, hanging from the gaff-end, was a string of flags. Evidently, she was signalling to us. All this, I saw in a flash, and I just stood and stared, astonished. I was astonished because I had not seen her earlier. In that light breeze, I knew that she must have been in sight for at least a couple of hours. Yet I could think of nothing rational to satisfy my wonder. There she was--of that much, I was certain. And yet, how had she come there without my seeing her, before? All at once, as I stood, staring, I heard the wheel behind me, spin rapidly. Instinctively, I jumped to get hold of the spokes; for I did not want the steering gear jammed. Then I turned again to have another look at the other ship; but, to my utter bewilderment, _there was no sign of her_--nothing but the calm ocean, spreading away to the distant horizon. I blinked my eyelids a bit, and pushed the hair off my forehead. Then, I stared again; but there was no vestige of her-- nothing, you know; and absolutely nothing unusual, except a faint, tremulous quiver in the air. And the blank surface of the sea reaching everywhere to the empty horizon. Had she foundered? I asked myself, naturally enough; and, for the moment, I really wondered. I searched round the sea for wreckage; but there was nothing, not even an odd hen-coop, or a piece of deck furniture; and so I threw away that idea, as impossible.
