had covered some hundred yards from shore

I had covered some hundred yards from shore when it became evident that my pursuer must grasp the stern of the skiff within the next half-dozen strokes. In a frenzy of despair, I bent to the grandfather of all paddles in a hopeless effort to escape, and still the copper giant behind me gained and gained.
His hand was reaching upward for the stern when I saw a sleek, sinuous body shoot from the depths below. The man saw it too, and the look of terror that overspread his face assured me that I need have no further concern as to him, for the fear of certain death was in his look.

And then about him coiled the great, slimy folds of a hideous monster of that prehistoric deep—a mighty serpent of the sea, with fanged jaws, and darting forked tongue, with bulging eyes, and bony protuberances upon head and snout that formed short, stout horns.

As I looked at that hopeless struggle my eyes met those of the doomed man, and I could have sworn that in his I saw an expression of hopeless appeal. But whether I did or not there swept through me a sudden compassion for the fellow. He was indeed a brother-man, and that he might have killed me with pleasure had he caught me was forgotten in the extremity of his danger.
