tobacco. All we Lapins need to keep us happy is a good solid vice like smoking." I looked at the Chief. "Why'd you follow me here, Dr. McQueen? I know I've been naughty." "Self-pity doesn't become a man, Johnny," he said. "And why the hell not?" I demanded, my blood-pressure ready to challenge any manometer in sight. "If I can feel compassion for some poor joker on TV, why can't I hurt a little for myself—for John Bogardus, swaddled from his darling by a damned plastic diving-suit? I was—I am—in love with Anne, Doctor." "Your marriage-night would kill you, John," he said. I jumped up with ready-made fists, then flopped down onto the grass, laughing at the picture I saw. Battle of the Century. In this corner, wearing helmet, chastity-suit, and thirty-five feet of air-hose Roy McQueen, Ph. D.

"I could have married Anne, and made her either an unkissed bride or an early widow," I said. "Neither of these alternatives struck me as an attractive career for the woman I love, so I left her. It's so logical it's practically simple arithmetic. Anne put up a fight to keep me, Chief; it was most warming to my amour-propre. Women aren't logical like us men of science. What a stinking situation!" "It is," Dr. McQueen said. "But remember, John, lovers outside the Big Tank often get just as star-crossed as you and Anne." "And they have dental caries to contend with, which we don't," I said. "Somehow, Chief, we'll get this experiment into its second generation, past the
