The fire she produced by rubbing two stones together. It seemed to ignite the stones, with a tiny flickering flame like the burning of sulphur. She had gathered a pile of dried vegetation from the surface above the cave; and when that was blazing she added rocks that glowed like coal. The fire interested me tremendously. It alarmed me; but only at first, for I saw that the girl had no fear of it.

I need not go into details. Her manner was proud when presently she indicated the hot food ready to eat and she watched me expectantly while I tasted it. I smiled my approval and beckoned her to take some of it with me. At which she curled up on the robe beside me, eating the food I pushed toward her.

We were friends. Like myself, she had no spoken language. But when we tried to talk it came fast. I indicated myself and told her I was Nemo. The word seemed to spring readily to my mind; I have no doubt it was some part of my earlier life. She had no name. I called her Nona. It seemed to please her. She repeated it after me half a dozen times, and clapped her hands delightedly.

A little later we went up to the surface of our tiny world. It chanced to be daylight; and Nona taught me how to swim through the air, how to handle myself against this lack of gravity.

The art came to me quickly. I was soon able to swim about with swift, powerful strokes. My stronger muscles gave me an advantage over her. I could swim more quickly; but I could never attain her deftness, her agility. She would swoop about, dive head downward in a graceful arc, right herself and land on tip-toe.

We circled our little globe, swimming at an altitude of a hundred feet, and following the Sun; and within half an hour were back at our starting point. Everywhere I saw the same bleak landscape. It was night when we returned, for we had overtaken the Sun and passed it. But in a few moments daylight came again.

Then Nona showed me how to jump. With arms folded, she leaped vertically into the air. Straight up her body shot, her hair brushed flat against her by the downward rush of wind. She held herself upright by throwing out a hand occasionally. Like an arrow she mounted; until standing on the ground I could see her only as a tiny dark speck against the blue of the sky.

She came swimming down a few moments later, her hair waving like a cloak behind her, spun gold with the sunlight on it. She was laughing and flushed from the exertion.

Then at arm’s length with fingers clasped, we leaped upward together. The tiny world dropped away. Looking down, it showed itself as a ball. I could see far around it.

We seemed to mount endlessly. The air grew so rare I gasped for breath. My head was roaring. I was cold. Below, I could see the spherical meteor turning under us. We were in Space, no longer a part of our world. And we had almost reached the limit of its atmosphere.
