The landing crew was composed of all men not at regular stations; nearly half of the _Kalid's_ entire crew. They were equipped with the small atomic power pistols as side-arms, and there were two three-men disintegrator ray squads. We all wore menores, which were unnecessary in the ship, but decidedly useful outside. I might add that the menore of those days was not the delicate, beautiful thing that it is to-day: it was comparatively crude, and clumsy band of metal, in which were imbedded the vital units and the tiny atomic energy generator, and was worn upon the head like a crown. But for all its clumsiness, it conveyed and received thought, and, after all, that was all we demanded of it. I caught a confused jumble of questioning thoughts as I came up, and took command of the situation promptly. It will be understood, of course, that in those days men had not learned to blank their minds against the menore, as they do to-day. It took generations of training to perfect that ability. "Open the exit," I ordered Kincaide, who was standing by the switch, key in the lock. "Yes, sir," he thought promptly, and unlocking the switch, released the lever. The great circular door revolved swiftly, backing slowly on its fine threads, gripped by the massive gimbals which, as at last the ponderous plug of metal freed itself from its threads, swung the circular door aside, like the door of a vault. * * * * * Fresh clean air swept in, and we breathed, it gratefully. Science can revitalize air, take out impurities and replace used-up constituents, but if cannot give it the freshness of pure natural air. Even the science of to-day. "Mr. Kincaide, you will stand by with five men. Under no circumstances are you to leave your post until ordered to do so. No rescue parties, under any circumstances, are to be sent out unless you have those orders directly from me. Should any untoward thing happen to this party, you will instantly reseal this exit, reporting at the same time to Mr. Correy, who has his orders. You will not attempt to rescue us, but will return to the Base and report in full, with Mr. Correy in command. Is that clear?" "Perfectly," came back his response instantly; but I could sense the rebellion in his mind. Kincaid and I were old friends, as well as fellow officers. I smiled at him reassuringly, and directed my orders to the waiting men. "You are aware of the fate of the two ships of the Patrol that have already landed here," I thought slowly, to be sure they understood perfectly. "What fate overtook them, I do not know. That is what we are here to determine."
