Though the cutter behaved very well, still there was a chance of our being pooped.  A strong current was setting us in the direction of the Longships light, which now appeared broad on the starboard bow.  We ran on, following, as we supposed, the Dolphin; but she was going faster than we were, and we soon lost sight of her.  We knew our exact position, for, although we had got beyond the gleam of Saint Agnes' Lighthouse, we could still see on our port-bow the two lights on board the light-vessel off the Seven Stones.  I own I wished that we were safe back in port, though papa appeared so cool that I could not suppose there was any real danger; still, as the seas came rolling up on either quarter, high above our deck, it seemed impossible that the vessel could escape being swamped.
