They were still separated, two on one side of the airlock, two on the Trouble was—their friendship was as dangerous as their hate! "Nope." "We'll get static on these things." A small infinity seemed to pass very slowly. bitterly. There was a wait during which everyone seemed to be holding their "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 though it were breathing and then it ruptured. Major Winship moved quickly to cut out the emergency air supply which "We've lost about three feet of calk out here," Capt. Lawler said. "I "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." "Damn!" Major Winship said, "they should have made these things more flexible." 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, space was more restricted than in a submarine, with the bunks jutting out from the walls about six feet from the floor. no comment was forthcoming, he continued: "Perhaps we built a bit more strongly, Major." this leak fixed. Skip, can you get the calking compound?" haven't got all day." A few minutes later, Lt. Chandler issued the triumphant cry. "Here it is! Dozen tubes. Squeeze tubes. It's the new stuff." They huddled over the instruction sheet. "Let's see. Squeeze the tube until the diaphragm at the nozzle ruptures. Extrude paste into seam. Allow to harden one hour before "As long as they'll loan us the calking compound," Capt. Wilkins said. "Let's eat." "You got any concentrate? I'm empty." "I'll load you," Capt. Wilkins volunteered wearily. It was an awkward operation that took several minutes. Capt. Wilkins cursed twice during the operation. "I'd hate to live in this thing for any period." "I think these suits are one thing we've got over the Russians," Major Winship said. "I don't see how they can manipulate those bulky pieces of junk around." They ate. "Really horrible stuff." "Nutritious." "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." "They've been here six years longer, after all." office is about ten by ten. Think of that. One hundred square feet. And a wooden desk. A 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 "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." "However," he continued, "we did experience a minor leak in the dome, has tendered their official apology. You want it?" "It can wait until later. Send it by mail for all I care. Vacuum has destroyed our organic air reconditioner. We have approximately three necessary replacement." The wait of a little better than three seconds for the response gave the conversation a tone of deliberation. I never felt so ... idiotic is not quite strong enough ... there for a minute in my whole life. I didn't know how much emergency air was left, and I thought, my God, I'll never live this down. All the hams in the 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. "That," said Capt. Lawler, "is the calking compound." "I am not kidding." Capt. Lawler and Lt. Chandler came inside. Capt. Wilkins mounted a bunk. "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 "Well, like I said, it's this way," Lt. Chandler resumed. "I told him we needed about a pint. Maybe a quart. But this stuff you have to mix up. He only had these drums. There's two parts to it, and you have to 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, surprised look, like everybody, everywhere has dozens of little scales." "Well, anyway," Lt. Chandler continued, "he told us just to mix up the whole fifty-five gallon drum. There's a little bucket of stuff that goes in, and it's measured just right. We can throw away what we don't need." "Somehow, that sounds like him," Major Winship said. "He had five or six of them." "Jesus!" said Capt. Wilkins. "That must be three thousand pounds of calking compound. Those people are insane." 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. carried it around the drum of calking compound and set it down. It "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." "No!" Major Winship snapped. With the drum of calking compound inside, both Capt. Lawler and Lt. Chandler retreated to the bunks. Capt. Wilkins maneuvered the mixing attachment. "I feel crowded," he said. "Cozy's the word." "Watch it! Watch it! You almost hit me in the face plate with that!" 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. like shrapnel." They obeyed. "What—what—what?" Capt. Lawler stuttered.
