He slipped one hand out of its boot, removed his big spectacles, and blinked his weak eyes. I watched him narrowly. His face was hairless. It might have been the face of an old woman or of an old man. A look of cunning now crept over it.

"I think," he said, "that I grasp your difficulty. You may speak of me as a man; but for beings of the first class, to which I belong, sex is abolished. It was perhaps the worst of nature's evils that our triumphant civilisation in the process of centuries overcame."

"But in that case," I said, "your race, or that class of it to which you belong, must be rapidly dying out."

"It is undoubtedly dying out," said the strange creature with a complacent smile, "but less rapidly than a barbarian would suppose. Increased knowledge has brought with it increased longevity. I am myself one hundred and ninety-two years of age. The end must come, of course, but after all, why not?"

As I looked at him I did not from the æsthetic point of view see why not. The creature had replaced the spectacles now, and lay at full length on the sand, as if wearied by the standing position. He went on speaking:

"Death in the individual is, of course, to some extent a confession of failure. It means inability, mostly due to ignorance, to adapt oneself to one's environment. Death of a race may be quite a different matter—an exhaustion of utility. However that may be, it is clear that the last of us to survive will represent the highest possible development of human potentiality. I speculate sometimes on the question of who the ultimate survivor will be. It may possibly be Professor YM6403 of the Outer Office. Some think so. I believe he thinks so himself. On the other hand, I may be the last survivor. However, there are still some thousands of us in existence, and for the present these disquisitions may appear to you idle."

My clothes were damp and I was chilly, hungry, and tired. His jabber about professors and survivors had no interest for me. I ventured to point out to him that I was at present in urgent need of rest and refreshment.

He rose on all fours again, and did so with extreme awkwardness. "True," he said. "I will attend to it. We are hospitable people, though it is seldom that a stranger visits us. I will proceed at once to conduct you to my house."

"Your house? I fear that must be at some great distance, for there is no house in sight."

For a moment he looked puzzled, and then light dawned again in his short-sighted eyes.
