Capt. Wilkins flicked off the transmitter. "Some days you don't mine at all," he said. "Les, have you found it?" "It's around here somewhere. Supposed to be back here." "Well, _find_ it." Lt. Chandler began moving boxes. "I saw it--" "Skip, help look." Capt. Lawler got down from the bunk and Major Winship mounted. "We 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." Major Winship got down and Capt. Wilkins got up. "Marker showed it over here," Major Winship said, inching over to the wall. He traced the leak with a metallic finger. "How does this stuff work?" Capt. Lawler asked. 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 service." Major Winship said dryly, "Never mind. I notice it hardens on contact with air." Capt. Wilkins lay back on the bunk and stared upward. He said, "Now that makes a weird kind of sense, doesn't it?" "How do they possibly think--?" "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." "How're the other ones?" asked Major Winship. Lt. Chandler turned and made a quick examination. "Oh, they're all hard, too." "Who was supposed to check?" demanded Capt. Wilkins in exasperation. "The only way you can check is to extrude it," Lt. Chandler said, "and if it does extrude, you've ruined it." "That's that," Major Winship said. "There's nothing for it but to yell help." II Capt. Lawler and Lt. Chandler took the land car to Base Gagarin. The Soviet base was situated some ten miles toward sunset at the bottom of a natural fold in the surface. The route was moderately direct to the tip of the gently rolling ridge. At that point, the best pathway angled left and made an S-shaped descent to the basin. It was a one-way trip of approximately thirty exhausting minutes. Major Winship, with his deficient reefer, remained behind. Capt. Wilkins stayed for company. "I want a cigarette in the worst way," Capt. Wilkins said. "So do I, Larry. Shouldn't be more than a couple of hours. Unless something else goes wrong." "As long as they'll loan us the calking compound," Capt. Wilkins said. "Yeah, yeah," Major Winship 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."
