been greatly simplified. In post-war Japan Walt Sheldon has found not only serenity, but complete freedom to write undisturbed about the things he treasures most. A one-time Air Force officer, he has turned to fantasy in It is not difficult to understand why. houlihan's The working model and the fact that the small people with their quick eyes and clever fingers could by ... Walt Sheldon The tiny spaceship had been built for a journey to a star. But its small, mischievous pilots had a rendezvous with destiny—on Earth. I must spot all sorts of minute shortcomings noises. It was in a park near the nuclear propulsion center—a cool, each other to hush, be quiet, and the soft breeze stirring them up was a great help. And I was a secluded little green sanctuary just over the hill from Mr. Riordan's again. I had known precisely such and under all conditions of friction and combustion." "Thank you, Mr. Houlihan," said Keech. All his people had gathered in a loose circle, as though attending his lighter moments, to bring us such brightly sparkling little gems as this. "Mr. Houlihan," said Keech, leprechauns. If we ever meet again, upon another world perchance, you'll find our friendship always eager and ready." "Thank you," I said. "And now, Mr. Houlihan," said gold is delivered to your rooms tonight, and so keep my part of the what the drive amounts to despite people. "We'll have three cheers now, do you hear, for Mr. Houlihan—friend of the little people as long as he shall live!" And they cheered. And little tears crept into the corners of some of much of this that if you're not a nuclear engineer yourself it's certain Perhaps you had better take my word for it that without this equation—correctly stated, mind you—mankind would be well advised not named Kevin Francis Houlihan. But I am, after all, a scientist. If I had not been a specialist in my field I would hardly have found myself engaged in vital research at the center. their spaceship to work now, and later, if they tried to spy out the right information I would take special at me. "Stop starin' and get to determined the true coefficient of in the glade with Keech and his working model. It would go down in scientific literature now, I suppose, as Houlihan's group of little people, hard at work. There was a leader, an older one do without Keech's pot of gold, though it would have been pleasant Equation, and that was honor with a crank face. He was beating him out of the gold to boot, for leprechauns are most clever in matters of this sort and he would have had it back soon enough—or else made it a burden in some way. Indeed, I had done a piece of work greatly to my advantage, and also to the advantage of humankind, and when a man can do the first and include the second as a fortunate byproduct it is a most happy accident. For if I had shown the little people how to make a spaceship they never seen them so busy, either. They were building something in would it be in that event? I ask you now, wouldn't we be even more likely to blow ourselves to Kingdom Come without the little people here work! You'll not be needin' to mind that man standin' there! You know he can't see nor hear us!" for us to believe in every now and "Come along now, people!" said this crotchety one, looking straight Extensive research did not uncover any evidence that the U.S. foreman of the leprechauns—if that's what he was—saw me smile Oh, it was good to hear the rich then? Transcriber's Note: with us! He's a believer! Run everybody—run for your lives!" even if I had latched on to a fine job of work for almost shamefully generous pay. You see, in a place as full of science as the nuclear propulsion center there is not much time for the old things. I very much wanted to talk to the little people. I walked over to the center of the glade where the curious shiny object was standing. It was as smooth as glass and shaped like a almost miraculously complete and workable. and looked about the glade. I knew they were all hiding nearby, watching Houlihan of the Roscommon Houlihans. father used to say! Come on out now, and pass the time o' day!" Then I waited, but they didn't stood there. The others all followed at a safe distance. I smiled to reassure "And mine's Houlihan, as I've "Mr. Houlihan," said Keech, living for many centuries I am all too acutely aware of the perversity of human nature." "Yes," I said. "Well, as you will quickly see, all I want to do is Houlihan." all he wants," standing. "Have your say, Mr. Houlihan. And afterward we'll appreciate it if you'll go away and leave us to our work." "Well, now, your work," I said, and glanced at the spaceship. "That's exactly what's got me curious." "It just so happens I'm a doctor of science." "A doctor of science, now," said Keech. "Invited by the American government to work on the first moon rocket here at the nuclear propulsion center. Since it's no secret I can advise you of it." "A scientist, is it," said Keech. "Well, now, that's very interesting." "I'll make no apologies for it," I "Oh, there's no need for apology," said Keech. "Though in truth we prefer poets to scientists. But it has just now crossed my mind, Mr. Houlihan that you, being a scientist, might be of help to us." "How?" I asked. "But continue." "We had to come here," said Keech, "to learn how to make a inclined," said Keech. "Their major passions are music and laughter and mischief, as anyone knows." "Myself included," I agreed. yourselves." "There is the planet, you say. And where would you be going?" "There's another committee working on that. 'Tis not our concern. I was inclined to suggest the construction. Naturally, we didn't understand all of your high-flyin' science, but some of our people are when you're thinkin' of us, and of course truly believin' in us. I don't know—'tis a thing of the mind, and not important at the moment. What's important is for us to get and then we'll be on our way." "You're determined to go." "Truly we are, Mr. Houlihan. Now—to business. Just during these last few minutes a certain matter has crossed my mind. That's why I'm wastin' all this time with you, sir. You say you are a scientist." "A nuclear engineer." "Well, then, it may be that you can help us—now that you know we're here." "Help you?" "The power control, Mr. Houlihan. As I understand it, 'tis necessary "Whatever it might be named," said Keech, shrugging. "'Tis the one thing we lack. I suppose eventually finally, "why should I help you?" "Ha!" said Keech, grinning, but not with humor, "the avarice of humans! I knew it! Well, Mr. Houlihan, I'll give you reason enough. The pot o' gold, Mr. Houlihan!" about the whole project. It was a most fascinating session. I had often wished for a true working model at the center, but no allowance as you would a needle, I was able to make many sensible observations and even a few innovations. or the center itself would pass by, and stop to watch me. But of course or anything the leprechauns had made, not being believers. I would halt work, pass the time
