The Devil's Asteroid

It was not very large, as asteroids go, but about it clung a silvery mist of atmosphere. Deeper flashes through the mist betokened water, and green patches hinted of rich vegetation. The space-patroller circled the little world knowledgeably, like a wasp buzzing around an apple. In the control room, by the forward ports, the Martian skipper addressed his Terrestrial companion. At first view it wasn't really bad. At second, it wasn't really strange. The sky, by virtue of an Earth-type atmosphere, shone blue with wispy clouds, and around the small plain on which he stood sprouted clumps and thickets of green tropical trees. Heathery ferns, with white and yellow edges to their leaves, grew under his bare feet. The sun, hovering at zenith, gave a July warmth to the air. The narrow horizon was very near, of course, but the variety of thickets and the broken nature of the land beyond kept it from seeming too different from the skyline of Earth. Parr decided that he might learn to endure, even to enjoy. Meanwhile, what about the other Terrestrials exiled here? And, as Parr wondered, he heard their sudden, excited voices.
