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. Nona’s fingers clutched mine tightly. Suddenly she twisted me downward and dropped me. A strong side wind had sprung up. We swam down against it, fighting our way until we at last were back to the meteor’s surface. I was tired, for through my clumsiness I had used far more energy than Nona; but I would not let her see it. I saw her look upon the muscles of my arms and shoulders, and her admiration pleased me. I stretched my arms for her, showed her the muscles of my legs; and looked about for some way of displaying my prowess. There were many boulders around that could be loosened. One by one I flung them into the air, sent them into Space never to return. * * * * * Nona watched me with awe, encouraging me with little syllables of pleasure as I selected larger and larger rocks. Some I dug up and tore loose, until at last I ripped off the top and side of a hill. It was a mountain of rock. I staggered like Atlas, with it over my head, and then launched it into the air. It rose a short distance, and fell back to form another hill. Nona gazed at me with new respect and with a look in her eyes that made my heart pound. I was casting about for some larger burden, but she drew me away. I was pleased. A sense of my own power filled me. I was master here on this world of mine. I could have taken it apart bit by bit and tossed it into Space. I could tear down mountains, build others in their stead. [Illustration: “_With my slight weight, I could lift huge masses of stone._”] Facts and figures? I am in a position now to give them to you. My meteor had a diameter of five miles, a circumference of some fifteen. Its density relative to Earth was .67. Its surface gravity—again relative to your Earth—was .00039, placing Earth as 1.00. My weight at the surface of my meteor—neglecting other factors which I shall name in a moment—was slightly over one ounce. Without undue exertion I could leap upward nearly ten thousand feet—that is to say, almost two miles. And the mountain of rock I tossed into the air on your Earth would have weighed some 320,000 pounds! I have said that the boulders I tossed upward left the surface of the meteor never to return. At an initial velocity of 13 feet a second, all objects became satellites of the meteor, revolving about it comparatively close to the surface in perfect circles. The velocity of escape was but 18½ feet a second, i. e., that velocity which would cause an object to pass into outer Space, moving onward until it found some larger body to encircle.
