"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?"
