As he threw the last switch, he became aware of a soft scuffling sound behind him, and turned to see tiny Dr. Y Chi Tung, single-handedly manhandling through the double bulkhead the bulky magnetic resonance device on which he had been working when the flare alarm sounded, and having the utmost difficulty even though the near free-fall conditions made his problem package next to weightless. The monkeylike form of the erudite physicist, dwarfed by the big chassis, gave the appearance of a small boy trying to hide an outsize treasure; but the nonchalant humor that normally poked constant fun at both his profession as a physicist and the traditions of his Chinese ancestors, was lacking. Dr. Ishie was both breathless and worried. "Mike," he gasped. "I was afraid to leave it, unshielded. It might pick up some residual activity. Radiation, that is. From those hydrogen hordes outside." He let the object rest for a moment, mopping his head while he talked. "Can you hide it in here? I'm not really anxious to have Budget Control know where some of this stuff went--even though I have honorable intentions of returning the components later--and the good captain down there on the bridge might not consider its shielding important, either, if he knew I'd sabotaged his beautiful evacuation plan to bring my pet along!" The tone of Ishie's voice indicated his uncertainty as to Mike's reception. The idea of Dr. Y Chi Tung worrying about any components he might have "requisitioned" seemed almost irreverent to Mike. Budget Control would gladly have given that eminent physicist a good half of the entire space station, if he had expressed his needs through the proper channels--as a matter of fact, anything on board that wasn't actually essential to the lives of those on the satellite. * * * * * But Ishie seemed genuinely unaware of his true status, and the high regard in which he was held. Besides, Mike suspected in him a constitutional inability to deal through channels. Recognizing the true sensitivity that underlay Ishie's constant humor and ridicule of himself, Mike kept himself from laughing aloud at the stealth of the man who could have commanded the assistance of the captain himself in shielding whatever he thought it necessary to shield. Instead, he carefully kept his face solemn while he commented: "It ought to fit in that rack over there." He pointed to a group of half-filled racks. "We can slip a fake panel on it. Nobody will be able to tell it from any of the other control circuits." Ishie heaved a deep sigh of relief and grinned his normal grin. "Confusion say," he declared, "that ninety-six pound weakling who struggle down shaft with six hundred pound object, even in free fall, should have stood in bed."
