""I want to ask you if you ever saw a man with gills like a fish?"
In Search of the Unknown (1904) by Robert W. Chambers
....I had been asleep for at least two hours when a movement by my bedside and a light in my eyes awakened me. I sat bolt upright in bed, blinking at Halyard, [25]who, clad in a dressing-gown and wearing a night-cap, had wheeled himself into my room with one hand, while with the other he solemnly waved a candle over my head.
"I'm so cursed lonely," he said—"come, there's a good fellow—talk to me in your own original, impudent way."
I objected strenuously, but he looked so worn and thin, so lonely and bad-tempered, so lovelessly grotesque, that I got out of bed and passed a spongeful of cold water over my head.
Then I returned to bed and propped the pillows up for a back-rest, ready to quarrel with him if it might bring some little pleasure into his morbid existence.
"No," he said, amiably, "I'm too worried to quarrel, but I'm much obliged for your kindly offer. I want to tell you something."
"What?" I asked, suspiciously.
"I want to ask you if you ever saw a man with gills like a fish?"
"Gills?" I repeated.
"Yes, gills! Did you?"
"No," I replied, angrily, "and neither did you."
"No, I never did," he said, in a curiously placid voice, "but there's a man with gills like a fish who lives in the ocean out there. Oh, you needn't look that way—nobody ever thinks of doubting my word, and I tell you that there's a man—or a thing that looks like a man—as big as you are, too—all slate-colored—with nasty red gills like a fish!—and I've a witness to prove what I say!"
"Who?" I asked, sarcastically.
"The witness? My nurse."
"Oh! She saw a slate-colored man with gills?"
"Yes, she did. So did Francis Lee, superintendent of the Mica Quarry Company at Port-of-Waves. So have a dozen men who work in the quarry. Oh, you needn't laugh, young man. It's an old story here, and anybody can tell you about the harbor-master."
"The harbor-master!" I exclaimed.
"Yes, that slate-colored thing with gills, that looks like a man—and—by Heaven! is a man—that's the harbor-master. Ask any quarryman at Port-of-Waves what it is that comes purring around their boats at the wharf and unties painters and changes the mooring of every cat-boat in the cove at night! Ask Francis Lee what it was he saw running and leaping up and down the shoal at sunset last Friday! Ask anybody along the coast what sort of a thing moves about the cliffs like a man and slides over them into the sea like an otter—"
"I saw it do that!" I burst out.
"Oh, did you? Well, what was it?"
Something kept me silent, although a dozen explanations flew to my lips.
After a pause, Halyard said: "You saw the harbor-master, that's what you saw!"
I looked at him without a word.
"Don't mistake me," he said, pettishly; "I don't think that the harbor-master is a spirit or a sprite or a hobgoblin, or any sort of damned rot. Neither do I believe it to be an optical illusion."
"What do you think it is?" I asked.
"I think it's a man—I think it's a branch of the human race—that's what I think.
