<passage>:
Bucky heaved the table off his lap and cursed me. "What's eating you, Jig? I'm not going to hurt him." curtains apart, had thick black hair on them and were not much larger than the hams of a Venusian swamp-rhino. He said, "Boss, Gertrude's actin' up again." "Gertrude be blowed," growled Bucky. "Can't you see I'm busy?" Gow's black eyes were unpleasant. "I'm tellin' you, Boss, Gertrude ain't happy. She ain't had the right food. If something...." I said, "That'll all be taken care of, Gow. Run along now." He looked at me like he was thinking it wouldn't take much timber to fit me for a coffin. "Okay! But Gertrude's unhappy. She's lonesome, see? And if she don't get happier pretty soon I ain't sure your tin-pot ship'll hold her." He pulled the curtains to and departed. Bucky Shannon groaned. Beamish cleared his throat and said, rather stiffly, "Gertrude?" "Yeah. She's kind of temperamental." Bucky took a quick drink. I finished for him. She was also much younger, but I didn't go into that. Gertrude may be a little creaky, but she's still pretty impressive. I only hoped she wouldn't die on us, because without her we'd have a sicker-looking rewarded them." I said, "Sure," rather sourly. Bucky hiccoughed. "Let's go see Gertrude." I didn't want to see Gertrude. I never got over feeling funny going into the brute tank, especially at night or out in space. I'm a city The fight had just put the topper on him. I was afraid he'd fall down the ladder and break his neck. That's why I went along. If I hadn't.... It was dark down there in the tank. Way off at the other end, there was a dim glow. Gow was evidently holding Gertrude's hand. We started down rank and sour and wild. And the sound of them, breathing and rustling in the dark, with the patient hatred walled around them as strong as the cage bars. Bucky Shannon lurched against me suddenly. I choked back a yell, and then wiped the sweat off my forehead and cursed. The scream came again. A high, ragged, whistling screech like nothing this side of hell, ripping through the musty darkness. Gertrude, on the wailing wall. It had been quiet. Now every brute in the place let go at the same time. My stomach turned clear over. I called Gertrude every name I could think of, and I couldn't hear myself doing it. Presently a great metallic clash nearly burst my eardrums, and the beasts shut up. Gow had them nicely conditioned to that gong. to put my back-hair up and snarl. Yeah. They were uneasy that night, all of a sudden.... Gow glared at us as we came up into the lantern light. "She's gettin' worse," he said. "She's lonesome." "That's tough," said Bucky Shannon. His grey-green eyes looked like an clear down to her flat, short tail, burn all colors. She looked like old Mother Misery herself, from way back before time began. Gow said softly, "She wants a mate. And somebody better get her one." Bucky Shannon sniffled again. I said irritably, "Be reasonable, Gow! cansin . There may not even be any." Gertrude screamed again. She didn't move, not even to raise her head. The sadness just built up inside her until it had to come out. That close, the screech was deafening, and it turned me all limp and cold inside. The loneliness, the sheer stark, simple pain.... Bucky Shannon began to cry. I snarled, "You'll have to snap her out of this, Gow. She's driving the rest of 'em nuts." He hammered on his gong, and things quieted down again. Gow stood looking out over the tank, sniffing a little, like a hound. Then he turned to Gertrude. He draped himself over my shoulder and we went off. Gow didn't look at us. Bucky sobbed. "You were right, Jig," he mumbled. "Circus is no good. I know it. But Gertrude. She's ugly and no good, but he loves her. I love...." "Sure, sure," I told him. "Stop crying down my neck." We were a long way from the light, then. The cages and tanks loomed rose up out of the darkness in little lazy coils, sparkling faintly with blue, cold fire. I yelled, "Gow! Gow, the Vapor snakes! Gow—for God's sake!" I started to run, back along the passageway. Bucky weighed on me, limp and heavy. The noise burst suddenly in a deafening hell of moans and roars and shrieks, packed in tight by the metal walls, and above it all I could hear Gertrude's lonely, whistling scream. I thought, " Somebody's down here. Somebody let 'em out. Somebody wants Bucky moaned and kicked under me. I remember hanging on and thinking, "This is it. This is it, and oh God, I'm scared!" Then I went out. He slapped some cold greasy stuff on my face. It hurt. I cursed him and said, "Where's Shannon? How is he?" "Mis' Bucky okay. You save life. You big hero, Mis' Jig. Mis' Gow come nickuhtime get snakes. You hero. Haw! You funny like hell!" I said, "Yeah," and pushed him away and got up. I almost fell down a couple of times, but presently I made it to the mirror over the "Question is, Jig, who wants to kill us, and why?" latch and looked at my feet. "And—uh—Jig, I...." I said, "Skip it. The next time, just don't trip me up, that's all!" and Gow, on the rare occasions he came up for air, went around looking like a disaster hoping to happen. To make it worse, Zurt the Jovian strong-man got hurt during the take-off, and the Mercurian cave-cat had kittens. I snarled, "What do you want, with this lousy dog-and-pony show!" and went out. He followed. The gang was converging on the lock, but they heat was already sneaking into the ship. While we passed the hatchway to the brute tank, I could hear Gertrude, screaming. The canvasmen were busy setting up the annex, slopping and cursing in He fell on his knees in the mud, making noises. It took him three or four tries to get our names out clear enough to understand. around to see what was happening. People began to close in on the man who crawled and whimpered in the mud. Kapper's face was horrible. I felt sick, listening to him fight for air. I wanted to go for a doctor anyway, but somehow I knew it was no use. Kapper whispered, " Cansin . Male. Only one. You don't know...! Take him back." "Keep this guy here till I get back," I said. Shannon stared at me. Beamish started to get indignant. "Shut up," I " Selak
