Then, as I stood, I got another thought, or, perhaps, an intuition and I asked myself seriously whether this disappearing ship might not be in some way connected with the other queer things. It occurred to me then, that the vessel I had seen was nothing real, and, perhaps, did not exist outside of my own brain. I considered the idea, gravely. It helped to explain the thing, and I could think of nothing else that would. Had she been real, I felt sure that others aboard us would have been bound to have seen her long before I had--I got a bit muddled there, with trying to think it out; and then, abruptly, the reality of the other ship, came back to me--every rope and sail and spar, you know. And I remembered how she had lifted to the heave of the sea, and how the sails had flapped in the light breeze. And the string of flags! She had been signalling. At that last, I found it just as impossible to believe that she had not been real. I had reached to this point of irresolution, and was standing with my back, partly turned to the wheel. I was holding it steady with my left hand, while I looked over the sea, to try to find something to help me to understand. All at once, as I stared, I seemed to see the ship again. She was more on the beam now, than on the quarter; but I thought little of that, in the astonishment of seeing her once more. It was only a glimpse, I caught of her--dim and wavering, as though I looked at her through the convolutions of heated air. Then she grew indistinct, and vanished again; but I was convinced now that she was real, and had been in sight all the time, if I could have seen her. That curious, dim, wavering appearance had suggested something to me. I remembered the strange, wavy look of the air, a few days previously, just before the mist had surrounded the ship. And in my mind, I connected the two. It was nothing about the other packet that was strange. The strangeness was with us. It was something that was about (or invested) our ship that prevented me--or indeed, any one else aboard from seeing that other. It was evident that she had been able to see us, as was proved by her signalling. In an irrelevant sort of way, I wondered what the people aboard of her thought of our apparently intentional disregard of their signals. After that, I thought of the strangeness of it all. Even at that minute, they could see us, plainly; and yet, so far as we were concerned, the whole ocean seemed empty. It appeared to me, at that time, to be the weirdest thing that could happen to us.
