Earth coins." "Oh, that. Sure, I remember—Hey! You didn't!" "Yes. We made about a billion dollars on that one." A hayseed Martian among big-planet slickers ... of course he would get into trouble. But that was nothing compared the U.S. copyright on this publication was renewed.] to a select few—' That's our largest dollar-earning enterprise." He would have liked to say it was his suggestion originally, but it would have been too presumptuous. He was talking to an Earthman, who only hope. I've been wondering, maybe we could organize a Martian "I'll say you do! With a Martian!" Peri narrowed her silver-blue gaze and looked icily at him. "You must have heard wrong, Gus. He's the heir apparent of Indonesia, Inc., or something. I got this Martian for you, see?" "So? Since when has all Mars had as much spending money as one big-time marijuana rancher? Not to mention the heir ap—" through the Martian atmosphere shuddered from the racket conducted by Earth's. The passport official seemed to bellow at him. "Pardon me for asking this. The United Protectorates welcome all visitors to Earth and I assure you, sir, an ordinary five-year visa provokes no questions. But since you came on an official courier boat of your planet, Mr. Matheny, regulations force me to ask your business." "Well—recruiting." Mars, would they?" that no one is interested any more in giving up even second-class citizenship on Earth to live in the Republic. But we only wanted to hire——uh, I mean engage—an, an advisor. We're not businessmen. We know our export trade hasn't a chance among all your corporations What the hell is the Martian Embassy here for? , thought Matheny, here I am, one solitary outlander in the greatest commercial empire the human race has ever seen, and I'm supposed to find my planet a con man! Mars had such machines. If ever. He wished gambling were legal on Earth. The Constitution of the Martian against, say, the Grant, Harding &amp Adams Public Relations Agency. customary form of challenge on Mars. Here, though, they simply pushed "You're from Mars, aren't you?" he asked in the friendliest tone "Nah. I am not doing one thing in particular. Besides, I have never met a Martian. I am very interested." "There aren't many of us on Earth," agreed Matheny. "Just a small embassy staff and an occasional like me." "I should think you would do a lot of traveling here. The old mother planet and so on." "We can't afford it," said Matheny. "What with gravitation and distance, such voyages are much too expensive for us to make them for pleasure. Not to mention our dollar shortage." As they entered the shaft, he added wistfully: "You Earth people have that kind of money, made a million years ago by a, uh, extinct race ... I tell you, she appreciated "Trouble with it is, I hear Mars is not so comfortable," said Doran. "I "I do know," said Matheny. "But we're poor—a handful of people trying to make a world of dust and sand and scrub thorn into fields and woods and seas. We can't do it without substantial help from Earth, equipment and supplies—which can only be paid for in Earth dollars—and we can't export enough to Earth to earn those dollars." Matheny shuddered. "Good Lord, no!" "Huh? But they make thyle right on Mars, don't they?" "Yes. And it all goes to Earth and sells at 2000 dollars a fifth. But you don't think we'd drink why do you call yourselves poor?" "Because we are," said Matheny. "By the time the shipping costs have been paid on a bottle, and the Earth wholesaler and jobber and sales engineer and so on, down to the retailer, have taken their percentage, and the advertising agency has been paid, and about fifty separate Earth taxes—there's very little profit going back to the distillery on Mars. The same principle is what's strangling us on everything. Old Martian artifacts aren't really rare, for instance, but freight charges and the middlemen here put them out of the mass market." "Have you not got some other business?" so on to people who like to act cosmopolitan, and I understand our travel posters are quite popular as wall decoration. But all that has to be printed on Earth, and the printer and distributor keep most of the money. We've sold some books and show tapes, of course, but only one has been really successful— I Was a Slave Girl on Mars . know, the title deeds to one square inch of Mars—but expressed business, I have heard." "It was our mainstay," admitted Matheny, "but it's been overworked. Martian stamps are a drug on the market. What we'd like to operate is a sweepstakes, but the anti-gambling laws on Earth forbid that." Doran whistled. "I got to give your people credit for enterprise, to, well, attract capital from Earth?" "Of course," said Matheny bitterly. "We offer the most liberal concessions in the Solar System. Any little mining company or transport But who's interested? We haven't a thing that Earth hasn't got more of. We're only the descendants of a few scientists, a few political "The only beer on Mars comes forty million miles, with interplanetary Martian. entertain quite a bit." Doran's brows lifted a few minutes of arc. "You're here on business, then?" "Yes. I told you we haven't any tourists. I was sent to hire a business manager for the Martian export trade." "What's wrong with your own people? I mean, Pete, it is not your fault there are so many rackets—uh, taxes—and middlemen and agencies and et cetera. That is just the way Earth is set up these days." Matheny's finger stabbed in the general direction of Doran's pajama top. "Exactly. And who set it up that way? Earthmen. We Martians are babes in the desert. What chance do we have to earn dollars on the scale we need them, in competition with corporations which could buy and sell our whole planet before breakfast? Why, we couldn't afford three seconds of commercial time on a Lullaby Pillow 'cast. What we need, what we have to hire, is an executive who knows Earth, who's an Earthman himself. Let him tell us what will appeal to your people, and how to dodge the tax bite and—and—well, you see how it goes, that sort of, uh, thing." York. Plus his retirement benefits, which he would lose if he quit where he is now at. And I am sure he would not want to settle on Mars business consultant and it was barely possible that he could arrange some contacts.... "No, no, no commission, all done in the interest of interplanetary friendship ... well, anyhow, let's not talk business now. If you have Mars really needs, get me?—is a confidence man." "A what?" "The best and slickest one on Earth, to operate a world-size con game for us and make us some real money." "Con man? Oh. A slipstring." "You are from Mars. Okay? So you fought bushcats barehanded in an "Well, you see, maybe a man like that is just what Mars does need. And He shrugged and gave the Martian a sidelong glance. "Sure, you may not They had instructed him on Mars to take chances if he must. "Oh, it's simple enough," said Matheny. "It's only that we already are operating con games." "On Mars, you mean?" "In this case, it helps to be at the far end of an interplanetary haul," said Matheny. "Not many Terrestrial archeologists get to Mars and they depend on our people to—Well, anyhow—"
