They were still separated, two on one side of the airlock, two on the other. lumbered directly away from the dome for a distance of about fifteen feet, then turned and positioned himself, some five feet behind the melting, yes. Melting down at the bottom a little. Now it's falling over to one side and laying on the air tank. The air tank is getting red, too. I'm afraid ... it's weakening it.... Redder. Oh, oh." Next morning, before the sunlight exploded, the four of them donned their space suits and went and sat outside the dome, waiting. The sun "The static level hasn't gone up much, if at all." "Maybe," Lt. Chandler said, "it's buried too deep." "Maybe so," Major Winship said. "But we can't have the dome fall down around all our ears." He stood. "Whew! You guys stay put." He crossed with the floating moon-motion to the airlock and entered, the illuminated central area. His foot was lifted for the second step when the floor beneath him rose and fell gently, pitching him forward, off balance. He stumbled against the table and ended up seated beside the radio equipment. The ground moved again. completely. It then abated to something in excess of normal. "Well," Lt. Chandler commented, "even though we didn't build this thing to withstand a moonquake, it seems to have stood up all right." "I guess I was just—" Major Winship began. "Oh, hell! We're losing He peeled back a marker and let it fall. Air currents whisked it away and plastered it against a riveted seam of the dome. It pulsed as though it were breathing and then it ruptured. Major Winship moved quickly to cut out the emergency air supply which He moved for the plastic sheeting. "We've lost about three feet of calk out here," Capt. Lawler said. "I can see more ripping loose. You're losing pressure fast at this rate." Major Winship pressed the sheeting over the leak. "How's that?" "Not yet." "I don't think I've got enough pressure left to hold it, now. It's sprung a little, and I can't get it to conform over the rivet heads." There was a splatter of static. "Damn!" Major Winship said, "they should have made these things more "Best I can do." Major Winship stepped back. The sheet began slowly to slide downward, then it fell away completely and lay limply on the floor. "Come on in," he said dryly. With the four of them inside, it was somewhat cramped. Most of the five hundred square feet was filled with equipment. Electrical cables trailed loosely along the walls and were festooned from the ceiling, his helmet against the speaker and then shook his head sadly. "We can't hear anything without any air." They huddled over the instruction sheet. "Gentlemen! It doesn't make any difference," Lt. Chandler said. "Some air must already have leaked into this one. It's hard as a rock. A gorilla couldn't extrude it." "The only way you can check is to extrude it," Lt. Chandler said, "and if it does extrude, you've ruined it." cursed twice during the operation. "I'd hate to live in this thing for any period." Capt. Wilkins raised eyebrows. "What brought this on?" "I was just thinking.... They really got it made, Larry. They've got better than three thousand square feet in the main dome and better than twelve hundred square feet in each of the two little ones. And there's only seven of them right now. That's living." wooden desk. And a chair. A wooden chair. Everything big and heavy. Everything. Weight, hell. Fifty pounds more or less—" "They've got the power-plants for it." "Do you think he did that deliberately?" Major Winship asked. "I think "If you've got all that power...." "That's the thing. That's the thing that gripes me, know what I mean? It's just insane to send up a heavy wooden desk. That's showing off. Like a little kid." "Maybe they don't make aluminum desks." "They've—got—aluminum. Half of everything on the whole planet is aluminum. You know they're just showing off." stresses in the long undisturbed satellite, and was done in the face of vigorous American protests." being inserted. Another tap indicated it was seated. Major Winship flicked the appropriate chest button and nodded in appreciation. "However," he continued, "we did experience a minor leak in the dome, which is presently being repaired." "The leak has not yet been repaired. Over and out." Capt. Lawler and Lt. Chandler returned with the calking compound. It occupied the rear section of the land car. Lt. Chandler sat atop it. It was a fifty-five gallon drum. "Why didn't you just borrow a cupful?" Major Winship said sarcastically. "It's this way," Lt. Chandler said. "They didn't have anything but 55-gallon drums of it." "Oh, my," said Capt. Wilkins. "I suppose it's a steel drum. Those things must weigh...." "Actually, I think you guys have got the general wrong," Capt. Lawler combine them in just the right proportion. He told me to take a little scale—" "A little scale?" asked Capt. Wilkins, rolling his eyes at the dome. "That's what I told him. We don't have any little scale." "Yeah," said Captain Lawler, "and he looked at us with that mute, whole fifty-five gallon drum. There's a little bucket of stuff that "He had five or six of them." "Jesus!" said Capt. Wilkins. "That must be three thousand pounds of It's supposed to be mixed thoroughly." They thought over the problem for a while. "That will be a man-sized job," Major Winship said. "We're going to have to bring the drum in," Capt. Wilkins said. "Well," said Capt. Lawler, "that will make it nice and cozy." It took the four of them to roll the drum inside, rocking it back and forth through the airlock. At that time, it was apparent the table was interposing itself. Lt. Chandler tried to dismantle the table. "Damn these suits," he said. "You've got it stuck between the bunk post." "I back the drum out." Reluctantly, they backed the drum out and deposited it. With the aid of carried it around the drum of calking compound and set it down. It rested uneasily on the uneven surface. "Now, let's go," said Major Winship. Eventually, they accomplished the moving. They wedged the drum between the main air-supply tank and the transmitter. They were all perspiring. "It's not the weight, it's the mass," said Capt. Wilkins brightly. "The hell it isn't the weight," said Lt. Chandler. "That's heavy." "With my reefer out," said Major Winship, "I'm the one it's rough on." He shook perspiration out of his eyes. "They should figure a way to get and touched the drum. He jerked back. "Ye Gods! that's hot! And it's harder than a rock! It is an epoxy! Let's get out of here." temporarily engaged with each other. Movement was somewhat ungainly in the space suits under the best of conditions, and now, with the necessity for speed, was doubly so. The other two crashed into them from behind, and they spewed forth from the dome in a tangle of arms and legs. At the table, they separated, two going to the left, two to the right.
