Nothing of the kind was evident here. There was, indeed, no lack of water. I could see a storm cloud gathering in the distance. The air I was breathing seemed unwarrantably moist; and all about me on the ground little pools remained from the last rainfall. But here there was no soil, not so much even as a grain of sand seemed to exist. The air was warm, as warm as a midsummer's day in my own land, a peculiarly oppressive, moist heat.

I had been prepared for this by Miela. I was bareheaded, since there never was to be direct sunlight. My feet were clad in low shoes with rubber soles. I wore socks. For the rest, I had on simply one of my old pairs of short, white running pants and a sleeveless running shirt. With the exception of the shoes it was exactly the costume I had worn in the races at college.

I had been standing motionless, hardly more than a step from the car in which we had landed. Suddenly, in the midst of my meditations on the strange scene about me, Miela said: "Go there, Alan."

She was smiling and pointing to a little rise of ground near by. I looked at her blankly.

"Jump, Alan," she added.

The spot to which she pointed was perhaps forty feet away. I knew what she meant, and, stepping back a few paces, came running forward and leaped into the air. I cleared the intervening space with no more effort than I could have jumped less than half that distance on earth.

Miela flew over beside me.

"You see, Alan, my husband, it is not so bad, perhaps, that I can fly."

She was smiling whimsically, but I could see her eyes were full of pride.

"There is no other man on Mercury who could do that, Alan," she added.
