"Ay, ay, I see her," I answered; for as the man spoke I caught sight of a small dark blur, which I knew must be a ship of some sort, showing indistinctly against the somewhat lighter background of cloud behind her.  She was about two miles away, and was steering a course that would carry her across our bows at a distance of about a quarter of a mile if we all held on as we were going; and for a moment I wondered whether it was our enemy the pirate brig again putting in an appearance.  But an instant's reflection sufficed to dissipate this idea, for, according to all the probabilities, the pirates ought by this time to be well on toward a hundred miles to the eastward of us, while the stranger was coming down, with squared yards, from the northward.
