O'Rielly had slammed the safety helmet on his head chance! Swiftly O'Rielly unlocked the controls and reset them. The "Well, Mr. O'Rielly?" O'Rielly wondered had Callahan passed out, was so long before the old "If every control hadn't been locked in correct setting," O'Rielly "So a control reset itself in flight, hey?" "Well, Mr. O'Rielly, you better know before we orbit Earth!" why did something crazy have to happen to O'Rielly's? In a in pre-flight school, no control had ever been known to slip. But one officers. Ever since Venus blast-off O'Rielly had been in Four's watch room. Nobody had passed through. O'Rielly knew it. Callahan knew it. By now the Old Woman herself, Captain Millicent Hatwoody, had probably Well, ma'am, O'Rielly searched every cranny where even a three-tailed mouse of Venus could have stowed away. His first flight, and O'Rielly saw himself washed out, busted to sweeper on the blast-off stands of either. Oh, she was a female human, though, this creature at which O'Rielly stood gaping. Yes, ma'am! resetting the control." O'Rielly suddenly felt like turning her over his knee and whaling her Yes, ma'am, O'Rielly was floating on a pink cloud with heavenly music in his head. Never felt so fine before. Except on the Venus layover when he'd been roped into a dice game with a bunch of Venus lads who had a jug to cheer one's parting with one's money. "Oh, that little thing."

Somehow he doubted that to shower the stink off yourself? Old Woman's taking a Venus bigwig on tour the ship. Old Woman catches you like you been rassling skunks myself here." Wherewith Callahan reached hand for O'Rielly's shower door. "Venus dames," O'Rielly said dreamily, "don't boss anything, do they?" Callahan yelped like he'd been bit in the pants by a big Jupiter ant. with knots in their tails. Before the guys who'd brought the Venus dames to Earth could say anything they was taken apart too small to pick up with a blotter. Earth dames wound up by flying the Venus ones "Venus boys rared up and served notice that if Earth ever got any funny notions, right away there wouldn't be enough Earth left to hide in an atom's eyebrow. Touchy as hornets on a hot griddle, them Venus guys. "No Venus dames allowed within fifty miles of their port. Earth guys stay inside the high-voltage fence. Any dame caught trying to leave Venus thrown to the tigers for supper. Same for any Earth guy caught around a Venus dame. In return, Earth could buy practically everything at bargain basement prices." dreamily. "But not a peek of any Venus dame." "Pray heaven you'll never lay eyes on one nor have one get within ten foot of you! Even though you'd know she'd be your damnation wouldn't was saved! And O'Rielly would now think of grand ways to save her O'Rielly's shower door, however, opened abruptly. O'Rielly had not opened it. O'Rielly, however, suffered a cruel stab of dismay. Surely O'Rielly's shower. Never in his right mind would any crewman dare fail to come stiffly erect the instant the Old Woman appeared. Behind her stood a colorfully robed specimen of Venus man. Handsome as the devil himself. Fit to snap lesser men in two with his highly bejeweled hands. Fuzzy beards trailed from his ears and kept twitching lazily as he sneered at the spectacle ever told any Venus man what to do. The shower units were equipped so no Burnerman need be more than two steps from his responsibility. To keep the Old Woman from possibly blowing her gaskets completely, O'Rielly simply stepped in, shut the O'Rielly's watch room. Was all O'Rielly could do to keep from busting yanked open the doors under O'Rielly's bunk.

"Yes! War in which people will actually die!" As His Excellency paled at that grisly remark, the Old Woman spoke through her teeth at "Presidents of Earth and Venus, please," the Old Woman stated evenly. "Interplanetary emergency." Highly groomed flunkies appeared on the panels and were impersonally efforts." Old Woman sighed through her teeth. "Venus woman aboard this ship. Stowaway. Rattle that around your belfries." The flunkies' faces went slack with shock, then were replaced by a The Venus panel finally held steady on universally notorious features, that were as fierce as an eagle's, in a fancy war helmet. "Trillium! My own granddaughter? Impossible! Dimdooly," Mr. President roared at his "Obviously Trillium's poor little brain has been drugged," His your official command! Weren't you, Trillium dear?" "No. One of us stowing away was the only way we Venus women could bring our cause to the attention of Earth's President. If Earth will only stop buying from Venus, you won't have any money to squander on your Venus manhood laying down the law. "That's the way things have been on Venus for ten thousand years and all the women in the universe can't change it!" "I have been in constant contact with my Cabinet during these the panel too. "From now on I'm doing the deciding." "Nonsense! You're only my wife!" "And new President of Venus, elected by unanimous vote of all women." "Impossible! The men run Venus!

Madame President of Venus, congratulations on your victory! "Long may the superior sex reign on Venus too! We shall be delighted to said in sudden thought.

Later, was part of organizing to take over Venus, I guess." O'Rielly still had memories of the way he had felt about Trillium "But I thought our boy was wearing the best fakes ever." "Ain't nothing can match the natural growed-on variety, no, ma'am. Venus guy kisses a Venus dame, his beards grabs her roundst the ears." "So what?" "Tickles 'em, boy, tickles 'em!"
