But not for some men and most boys! I've always said that even if Sis is seven years older than me—and a "Now, Miss Sparling, no hoopla. I'm saying let's get married, and you know it. You figured out from what the boy told you that I was chewing on you for a wife. You're healthy and strong, got good heredity, you ? Are—are you daring to suggest that—that—" yes !" jam-packed with three hundred females just aching to get themselves husbands in the one place they're still to be had—the planet girl besides—she don't always know what's best. Put me on a spaceship Eleanor Roosevelt ! Gee , I thought excitedly, this is one big ship ! Of course, every once in a while I would run across a big scene of going purr-purr-purrty-purr case of emergency. I looked for the important As I trotted along the crossway, I sort of wished that Sis hadn't decided to go after a husband on a luxury liner.

I only remembered one voice key—might as well see if that's it, I figured. "Twenty, Twenty-three. Open Sesame." For a second, I thought I'd hit it just right out of all the million blaster which I knew it was against the law for him to have at all, when I suddenly got scared right through. jumpy enough to splash." Then he shoved the blaster away in a holster made of the same scaly " What? " We're from Undersea."

He looked impressed when I told him about Mom and Pop being one of the first couples to get married in Undersea. He looked thoughtful when I told him how Sis and I had been born there and spent half our childhood listening to the pressure pumps. He raised his eyebrows and looked "Well, after the funeral, there was a little money, so Sis decided we might as well use it to migrate. There was no future for her on Earth, she figured. You know, the three-out-of-four." "How's that?" "The three-out-of-four. No more than three women out of every four on Earth can expect to find husbands. Not enough men to go around. Way back in the Twentieth Century, it began to be felt, Sis says, what with the wars and all. Then the wars went on and a lot more men began to die or get no good from the radioactivity. Then the best men went to the planets, Sis says, until by now even if a woman can scrounge a personal islands he had decided to go to Earth where there was supposed to be a and imagine !—he not only attorneys.

Twice, the mechanical hamper refused to accept my jacket for laundering and I had to wash it myself. But I learned so many wonderful things about Venus every time I visited that stowaway.... I learned how you tell the difference between a lousy government paddlefoot from New Kalamazoo and the slaptoe slinker who is the planter's friend. After a lot of begging, Butt Lee Brown explained the workings of his blaster, explained it the control swivel-chair at the nose of the lifeboat. "But way I look at it, a man who lets somebody else handle his blaster is like the giant whose heart was in an egg that an enemy found. When you've grown enough so's your pop feels you ought to have a weapon, why, then's the time to learn it and you might's well learn fast. Before then, you're All I have is Sis. And she —" tell him, my aunts on both sides of my family each had had more than Continent.

"Does it, now?" she said, looking at me as if I were beginning to grow a second pair of ears. "Tell me more." "You can't have meek, law-abiding, women-ruled men when you start civilization on a new planet. You've got to have men who aren't afraid to make their own law if necessary—with their own guns.
