"What was he doing under water?"

"He must have been tearing the bird to pieces. Oh, it was quite unpleasant, I assure you, Mr. Smith. And when he came up and looked at me out of those very vitreous eyes he resembled something horridly amphibious.... And I felt rather sick and dizzy."

"He's got to stop that sort of thing!" I said angrily. "Snake-birds are harmless and I won't have him killing them in that barbarous fashion. I've warned him already to let birds alone. I don't know how he catches them or why he kills them. But he seems to have a mania for doing it—"

I was interrupted by Grue's soft and rather pleasant voice from the water's edge, announcing a sail on the horizon. He did not turn when speaking.

The next moment I made out the sail and focussed my glasses on it.

"It's Professor Kemper," I announced presently.

"I'm so glad," remarked Evelyn Grey.

I don't know why it should have suddenly occurred to me, apropos of nothing, that Billy Kemper was unusually handsome. Or why I should have turned and looked at the pretty waitress—except that she was, perhaps, worth gazing upon from a purely non-scientific point of view. In fact, to a man not entirely absorbed in scientific research and not passionately and irrevocably wedded to his profession, her violet-blue eyes and rather sweet mouth might have proved disturbing.

As I was thinking about this she looked up at me and smiled.

"It's a good thing," I thought to myself, "that I am irrevocably wedded to my profession." And I gazed fixedly across the Atlantic Ocean.
