My log showed nearly a hundred "All's well" reports, as I remember it, when we slid up to Antri, which was, so far as size is concerned, one of our smallest ports o' call. Antri, I might add, for the benefit of those who have forgotten their maps of the universe, is a satellite of A-411, which, in turn, is one of the largest bodies of the universe, and both uninhabited and uninhabitable. Antri is somewhat larger than the moon, Earth's satellite, and considerably farther from its controlling body. "Report our presence, Mr. Croy," I ordered wearily. "And please ask Mr. Correy to keep a sharp watch on the attraction meter." These huge bodies such as A-411 are not pleasant companions at space speeds. A few minute's trouble--space ships gave trouble, in those days--and you melted like a drop of solder when you struck the atmospheric belt. "Yes, sir!" There never was a crisper young officer than Croy. I bent over my tables, working out our position and charting our course for the next period. In a few seconds Croy was back, his blue eyes gleaming. "Sir, an emergency is reported on Antri. We are to make all possible speed, to Oreo, their governing city. I gather that it is very important." "Very well, Mr. Croy." I can't say the news was unwelcome. Monotony kills young men. "Have the disintegrator ray generators inspected and tested. Turn out the watch below in such time that we may have all hands on duty when we arrive. If there is an emergency, we shall be prepared for it. I shall be with Mr. Correy in the navigating room; if there are any further communications, relay them to me there." * * * * * I hurried up to the navigating room, and gave Correy his orders. "Do not reduce speed until it is absolutely necessary," I concluded. "We have an emergency call from Antri, and minutes may be important. How long do you make it to Oreo?" "About an hour to the atmosphere; say an hour more to set down in the city. I believe that's about right, sir." I nodded, frowning at the twin charts, with their softly glowing lights, and turned to the television disc, picking up Antri without difficulty. Of course, back in those days we had the huge and cumbersome discs, their faces shielded by a hood, that would be suitable only for museum pieces now. But they did their work very well, and I searched Antri carefully, at varying ranges, for any sign of disturbances. I found none. The dark portion, of course, I could not penetrate. Antri has one portion of its face that is turned forever from its sun, and one half that is bathed in perpetual light. The long twilight zone was uninhabited, for the people of Antri are a sun-loving race, and their cities and villages appeared only in the bright areas of perpetual sunlight. Just as we reduced to atmospheric speed, Croy sent up a message
