HAGERTY'S ENZYMES By A. L. HALEY There's a place for every man and a man for every place, but on robot-harried Mars the Extensive research did not uncover any evidence that the U.S. copyright on this publication was renewed.] Harper Breen sank down gingerly into the new Relaxo-Lounge. He placed tenderly. With velvety cushions it massaged his back and arms and legs. For all of five minutes Harper stood it. Then with a frenzied lunge he escaped the embrace of the Relaxo-Lounge and fled to a gloriously stationary sofa. a four-alarm fire. And what does he prescribe? A blasted jiggling "Vacation!" he snorted. "Batting a silly ball around or dragging a hook after a stupid fish! Fine activities for an intelligent middle-aged man! And let me correct you. It isn't business worries that are driving me to a crack-up. It's the strain of trying to get some sensible, reasonable coöperation from the nincompoops I have to hire! It's the idiocy of the human race that's got me whipped! It's the—" with the harmony of his home. "You're away behind the times, Harp," he declared. "Don't you know that those have proved to be the most astoundingly curative springs ever discovered anywhere? Don't you know that a syndicate has built the largest extra-terrestial hotel of the solar system there and that people are flocking to it to get cured of whatever ails 'em? Old man, you missed a bet!" Scribney's hands. He glared at the spread which depicted a star-shaped structure of bottle-green glass resting jewel-like on the rufous rock skyscraper with a glass-domed roof. Between its star-shaped annexes, other domes covered landscaped gardens and noxious pools which in the drawing looked lovely and enticing. "Why, I remember now!" exclaimed Bella. "That's where the Durants went two years ago! He was about dead and she looked like a hag. They came back in wonderful shape. Don't you remember, Scrib?" they use in the rockets nowadays is as good as a rest-cure it sort of floats you along the time-track in a pleasant daze, they tell me. And you can finish the cure at the hotel while looking it over. And not only that." Confidentially he leaned toward his insignificant looking brother-in-law. "The chemists over at Dade McCann have just isolated an calculating. He even forgot to twitch. "Maybe you're right, Scrib," he acknowledged. "Combine a rest-cure with business, eh?" Raising the magazine, he began reading the advertisement. And that was when he saw the line about the robots. "—the only hotel staffed entirely with robot servants—" "Robots!" he shrilled. "You mean they've developed the things to that about it, whatever it is! If it's something at the Emerald Star Hotel, why don't you just go and find out for yourself instead of throwing a tantrum? That's the only sensible way!" lope. the hammock, made his way to the airlock, and found himself whisked by pneumatic tube directly into the lobby of the Emerald Star Hotel. Appreciatively he gazed around at the half-acre of moss-gray carpeting, green-tinted by the light sifting through the walls of Martian copper-glass, and at the vistas of beautiful domed gardens framed by a state of perfection. How, he wondered again, had this been done without his knowledge? Was Scrib right? Was he slipping? Gnawing at the doubt, he watched the robots moving efficiently about, pushing patients in expense! There'd be no more of that obnoxious personal friction and proneness to error that was always deviling the most carefully trained office staffs! He'd investigate and find out the exact potentialities the hotel is staffed entirely with robots. They're much more expensive, really, than human employees, but so much more efficient, you know. Admit it, they give excellent service, don't they, now?" Toothily he good. I might just as well have a set of push buttons in the room. I want are always civil. But you should know by now that civility isn't a normal human trait." Leaving her temporarily quashed, he beckoned authoritatively to the clerk. "I've just arrived and want to get settled. I'm here merely for a rest-cure, no treatments. You can assign my quarters before continuing your—ah—discussion with the lady." "Here you are, Mr. Breen. I'm sure you'll find it comfortable." With a pallid smile he pressed a button and consigned Harper to the care of a silent and efficient robot. The room was more than comfortable. It was beautiful. Its bank of clear windows set in the green glass wall framed startling rubicund views of the Martian hinterland where, Harper affectionately thought, fungi were busy producing enzymes that were going to be worth millions for him and and almost airless planet. Details for his bright young laboratory men mere details.... Leaving his luggage to be unpacked by the robot attendant, he went up to the domed roof restaurant. Lunching boldly on broiled halibut with consomme, salad and a bland custard, he stared out at the dark blue sky of Mars, with Deimos hanging in the east in three-quarter phase Enzymes. There's good money in it, but man, what a job! No air worth mentionin'. Temperature always freezin' or below. Pressure suits. Huts. Factory. Processed food. Nothin' else. Just nothin'. That's where they could use some robots. It sure ain't no job for a real live man. And in treatment I can get. Take me! I'm just a wreck, fellers—" and I'm getting your treatments. Why don't we switch rooms and see what happens?" that fancy lobby." Harper looked at his watch. "Time to go. Relax, old man. The robots downstairs in garb that makes a laughing stock of me? Do you know why? don't, somebody else will. And if nobody sues, we'll go broke anyway, at the rate our guest list is declining. I'm ready to hand in my resignation." reasonable price, of course—and forget the outrages I've suffered at your establishment." Hayes leaned toward him incredulous. "You mean you want these robots after what you've seen and experienced?" back you to the hilt! I'll notify the owners at once. At once, Mr. Breen! And while we wait for them, allow me to put you up as a guest of the hotel." Coming around to Harper, he effusively shook Harp's scrawny across the lobby to the elevator. Harper gazed out at the stunned audience. This was more like the inside the immense jacket and stepped into the elevator. He was ready for the second step of his private Operation Robot. Back on Earth it was a warm, misty spring day—the kind of day unknown to the planet Mars. Bella and Scribney, superb in new spring outfits, waited restlessly while the rocket cooled and the passengers recovered from deceleration. And indeed, Harper was stepping briskly downward, looking spry and fit again!" Harper smirked. "Yep, I turned a neat little deal. I bought out Hagerty's Enzymes and staffed the plant with the hotel's robots. Got both of 'em dirt cheap. Both concerns going bankrupt because they didn't have sense enough to swap their workers. Feel I owe you a bit after all. "All right! Yes, sir! But aren't you going to use some of those robots for office help? Aren't they efficient and all that?"
