Firmon of hydroponics slouched in, a tall man with scanty hair and an equal lack of grace. He seemed to have difficulty in taking his eyes off Meredith, though, since he was a notch or so above her in the mating scale, he shouldn't have been so interested. But his planet had been inexplicably slow in developing and he wasn't completely aware of his place in the human hierarchy. Disdainfully, Meredith adjusted a skirt that, a few inches shorter, wouldn't have been a skirt at all, revealing, while doing so, just how long and beautiful a woman's legs could be. Her people had never given much thought to physical modesty and, with legs like that, it was easy to see why. Muttering something about primitive women, Firmon turned to the biologist. "The pilot doesn't like our air." "Then change it to suit him. He's in charge of the ship and knows more about these things than I do." "More than a man?" Firmon leered at Meredith and, when she failed to smile, added plaintively, "I did try to change it, but he still complains." * * * * * Halden took a deep breath. "Seems all right to me." "To everybody else, too, but the tapeworm hasn't got lungs. He breathes through a million tubes scattered over his body." It would do no good to explain that Taphetta wasn't a worm, that his evolution had taken a different course, but that he was in no sense less complex than Man. It was a paradox that some biologically higher humans hadn't developed as much as lower races and actually weren't prepared for the multitude of life-forms they'd meet in space. Firmon's reaction was quite typical. "If he asks for cleaner air, it's because his system needs it," said Halden. "Do anything you can to give it to him." "Can't. This is as good as I can get it. Taphetta thought you could do something about it." "Hydroponics is your job. There's nothing _I_ can do." Halden paused thoughtfully. "Is there something wrong with the plants?" "In a way, I guess, and yet not really." "What is it, some kind of toxic condition?" "The plants are healthy enough, but something's chewing them down as fast as they grow." "Insects? There shouldn't be any, but if there are, we've got sprays. Use them." "It's an animal," said Firmon. "We tried poison and got a few, but now they won't touch the stuff. I had electronics rig up some traps. The animals seem to know what they are and we've never caught one that way." Halden glowered at the man. "How long has this been going on?" "About three months. It's not bad; we can keep up with them." It was probably nothing to become alarmed at, but an animal on the ship was a nuisance, doubly so because of their pilot. "Tell me what you know about it," said Halden.
