<passage>:
I felt the same way when he—that is, of course, I or we—came back to tell me about it, thirty years ago. Here, have one of these. You'll get to like them in a couple more but he—I—told me what I was going to do, so I might as well do the same. I probably couldn't help telling you the you'll want to go along. I'll be tired of talking by then, and in a hurry to get going. So I cut off your questions, and get you inside. I snap on a green button, and everything seems to cut off around us. You can see a sort of isn't protected, though. You start to say something, but by then I'm pressing a black button, turns over and pokes back at you. Doesn't hurt, and when you pull your arm back, you're still sound and uninjured. But it looks frightening and you don't try it again. anyway?" I'd told you that, too, but you've forgotten. "As near as I can guess, you see me going by, mixed into a crowd that is loafing along toward a restaurant, or something like it, that is just opening. I'm asking questions of a man, who points, and I turn and move off. But there is only a single picture of a dull-looking metal sphere, with passengers moving up a ramp, and the office is closed. You begin to get you'd figure it was some part in a play and let it go. Well, people don't change much. You get up your courage and go up to a boy selling something that might be papers on tapes. "Where can I find the Museum of Science?" "Downayer rien turn lefa the sign. Stoo bloss," he tells you. Around you, you hear some pretty normal English, but there are others using stuff as garbled as his. The educated and uneducated? I don't know. You go right until you find a big sign built into the rubbery surface of the walk: Miuzi:m *v Syens . There's an arrow pointing and you turn left. Ahead of you, two blocks on, you can see a pink building, with faint aqua trimming, bigger than most of the others. They are building hesitate for a moment, then. You're beginning to think the whole affair is complete nonsense, and you should get back to the time machine and go home. But then a guard comes to the gate. Except for the short legs in his suit and the friendly grin on his face, he looks like any other guard. guards as polite as that. "I—I'm told I should investigate your display of atomic generators." He beams at that. "Of course." The gate is swung to behind you, but of what seem to be bearings, and slips something the size of a penny toward you. "Souvenir," it announces in a well-modulated voice. "This is a typical gem of the twentieth century, properly cut to 58 facets, known technically as a Jaegger diamond, and approximately twenty carats in size. You can have it made into a ring on the third floor during morning hours for one-tenth credit. If you have more than one child, press the red button for the number of stones you desire." You put it in your pocket, gulping a little, and get back to the , filled with everything from a crossbow to a tiny rod four inches long and half the thickness of a pencil, marked Fynal Hand Arm . Beyond is the end of the corridor, and a big place that bears a sign, Mad:lz *v Atamic Pau:r Sorsez , is about the size of a desk telephone. The earlier ones are larger, of course, clumsier, but with variations, probably depending on the power output. A big sign You study it, but it mentions casually the inventor, without giving his name. Either they don't know it, or they take it for granted that everyone does, which seems more probable. They call attention to the fact that they have the original model of the first atomic generator each side. "Nice," the guard says over your shoulder. "It finally wore out one of the cathogrids and we had to replace that, but otherwise it's exactly Like to have me tell you about it?" "Not particularly," you begin, and then realize bad manners might be conspicuous here. While you're searching for an answer, the guard pulls something out of his pocket and stares at it. "Fine, fine. The mayor of Altasecarba—Centaurian, you know—is arriving, but I'll be back in about ten minutes. He wants to examine moves. There's a little sign under it, indicating you shouldn't touch it, since the gravostatic plate is being renewed. seems clear. Then you hear his voice from the weapons room. You bend down and try to scurry past, but you know you're in full view. Nothing happens, though. of your feet, with a sudden ringing sound. You don't wait to find out about that, either. Somebody reaches out a hand to catch you and you dart past. seeming to come out of the sockets, and that atomic generator getting heavier at every step. Out of nowhere, something in a blue uniform about six feet tall and on the beefy side appears—and the badge hasn't changed much. The cop catches your arm and you know you're not going to get away, so you stop. "You can't exert yourself that hard in this heat, fellow," the cop says. "There are laws against that, without a yellow sticker. Here, let me grab you a taxi." Reaction sets in a bit and your knees begin to buckle, but you shake "I—I left my money home," you begin. The cop nods. "Oh, that explains it. Fine, I won't have to give you an appearance schedule. But you should have come to me." He reaches out and taps a pedestrian lightly on the shoulder. "Sir, an emergency request. Would you help this gentleman?" The pedestrian grins, looks at his watch, and nods. "How far?" You did notice the name of the building from which you came and you mutter it. The stranger nods again, reaches out and picks up the other side of the generator, blowing a little whistle the cop hands him. Pedestrians begin to move aside, and you and the stranger jog down the street at a trot, with a nice clear path, while the cop stands beaming at you both. And he is. He stands just inside the door of the building as you reach it. The stranger lifts an eyebrow and goes off at once when you nod at him, not waiting for thanks. And the guard comes up, holding some dinkus in his hand, about the size of a big folding camera and not too dissimilar in other ways. He snaps it open and you get set to duck. we'll pick it up." You swallow several sets of tonsils you had removed years before, and take the bundle of papers he hands you out of the little case. He pumps you for some more information, which you give him at random. It seems to satisfy your amiable guard friend. He finally smiles in satisfaction down beside it, and climb into the cockpit, sweating and mumbling. You reach forward toward the green button and hesitate. There's a red one beside it and you finally decide on that. Suddenly, there's a confused yell from the direction of the elevator and a beam of light strikes against your eyes, with a shout punctuating it. Your finger touches the red button. You'll never know what the shouting was about—whether they finally doped out the fact that they'd been robbed, or whether they were trying to help you. You don't care which it is. The field springs up around you and the next button you touch—the one on the board that hasn't been used so far—sends you off into nothingness. There is no beam of Before long, your riches from the generator are piling in. Little kids from school are coming around to stare at the man who changed history and made atomic power so common that no nation could hope to came looking for you and shouting, before the time machine left.
