"I think it's a man—I think it's a branch of the human race—that's what I think. Let me tell you something: the deepest spot in the Atlantic Ocean is a trifle over five miles deep—and I suppose you know that this place lies only about a quarter of a mile off this headland. The British exploring vessel, Gull, Captain Marotte, discovered and sounded it, I believe. Anyway, it's there, and it's my belief that the profound depths are inhabited by the remnants of the last race of amphibious human beings!"

This was childish; I did not bother to reply.

"Believe it or not, as you will," he said, angrily; "one thing I know, and that is this: the harbor-master has taken to hanging around my cove, and he is attracted by my nurse! I won't have it! I'll blow his fishy gills out of his head if I ever get a shot at him! I don't care whether it's homicide or not—anyway, it's a new kind of murder and it attracts me!"

I gazed at him incredulously, but he was working himself into a passion, and I did not choose to say what I thought.

"Yes, this slate-colored thing with gills goes purring and grinning and spitting about after my nurse—when she walks, when she rows, when she sits on the beach! Gad! It drives me nearly frantic. I won't tolerate it, I tell you!"

"No," said I, "I wouldn't either." And I rolled over in bed convulsed with laughter.

The next moment I heard my door slam. I smothered my mirth and rose to close the window, for the land-wind blew cold from the forest, and a drizzle was sweeping the carpet as far as my bed.

That luminous glare which sometimes lingers after the stars go out, threw a trembling, nebulous radiance over sand and cove. I heard the seething currents under the breakers' softened thunder—louder than I ever heard it. Then, as I closed my window, lingering for a last look at the crawling tide, I saw a man standing, ankle-deep, in the surf, all alone there in the night. But—was it a man? For the figure suddenly began running over the beach on all fours like a beetle, waving its limbs like feelers. Before I could throw open the window again it darted into the surf, and, when I leaned out into the chilling drizzle, I saw nothing save the flat ebb crawling on the coast—I heard nothing save the purring of bubbles on seething sands.
