An aged man standing near by spoke to him. "It is the last time you shall fly through the air of this condemned world, O Rei," he murmured and sighed. Kuila scowled at the reminder of that fact, and pushed himself into the heart of the crowd. He found his way to one of the kiosks that housed an elevator and stepping in it he pressed the indicator for a floor a thousand feet below. The drop occupied less than a minute and he was in a corridor. He hurried along to an office wherein several people were still lingering. In the center of the room stood a machine with a mouthpiece on its face, and into this he dictated his report. He stated his name, age and occupation and explained that he had been the last to leave the observatory of Mount 83; that it was in perfect condition, a condition, he conjectured that would withstand the ice-flow that was slowly surmounting the peak on which the observatory stood. His report ended, he turned away. He knew that the machine would relay his report to an adjoining office, write it in indelible print on a thin metal sheet and file it away with similar reports in alphabetical and chronological order. * * * * * A Beautiful Companion With that done he left the office, returning to the shaft by which he descended. A girl was walking ahead of him, and they both reached the lift almost at the same moment. She was dressed exactly as Kuila Rei, and on her shoulder he descried insignia the same as he wore, the insignia of the astronomers. The suits of the Earthlings were made of a material that transmitted no heat, holding the normal body heat of the wearer. It was in two pieces, blouse and trousers. The trousers almost skin-tight fitted snugly at the hips. They were designed so as to contain the feet; and under the feet were sewn heavy pieces of felt that fitted the foot. The blouse was loose to give free movement to the torso. It fell straight from the shoulder half-way to the thighs and was caught tightly at the waist with a girdle. The sleeves hung rather full from shoulder to wrist and were buckled tightly; while the collar, rather high, fitted the neck closely. From the shoulders hung a hood that could be pulled over the head and fitted tightly about the face and chin. From it a mask could be drawn over the face to protect it in cases of extreme cold and to the mask were fastened small tubes for nose and mouth. These could be attached to an oxygen tank that the wearer would carry on his shoulders. Gloves were carried in one of the slit pockets of the blouse.
