Through the barred windows of the workshop, rolling green hills were institution. The crafts building was a good mile away from the main complex of buildings that housed the main wards. of advice here, and a suggestion there. She stopped behind a frowning, intense patient, rapidly shaping blobs of clay into odd-sized strips and forms. As he finished each piece, he carefully placed it into a hollow shell hemisphere of clay. The flying fingers continued to whip out the bits of shaped clay as the patient ignored the question. He hunched closer to his table as if to draw away from the woman. "We mustn't be antisocial, Mr. Funston," Miss Abercrombie said lightly, but firmly. "You've been coming along famously and you must remember to answer when someone talks to you. Now what are you making? It looks very complicated." She stared professionally at the maze of clay parts.

A tall, blond patient with a flowing mustache, put one more dab of paint on his canvas and stood back to survey the meaningless At the clay table, Funston feverishly fabricated the last odd-shaped bit made short, precise notes on the day's work accomplished by each patient. and stared thoughtfully at the jumbled maze of clay strips laced through lengthily in her chart book. The sun set, darkness fell over the stilled hospital grounds and the burning in each ward office. A quiet wind sighed over the still-warm hills. Funston turned to the window and stared out across the black hills that He gave a quick cry, shut his eyes and clapped his hands over his face. The brilliance of a hundred suns glared in the night and threw stark shadows on the walls of the suddenly-illuminated ward. An instant later, the shattering roar and blast of the explosion struck the hospital buildings in a wave of force and the bursting crash of a screams of the frightened and demented patients. It was over in an instant, and a stunned moment later, recessed ceiling Beyond the again-silent hills, a great pillar of smoke, topped by a the arts and crafts building. with a small, secret smile on his lips. Attendants and nurses scurried through the hospital, seeing how many had been injured in the explosion. None had. The hills had absorbed most of the shock and apart from a welter of broken glass, the damage had been surprisingly slight. The roar and flash of the explosion had lighted and rocked the surrounding countryside. Soon firemen and civil defense disaster units from a half-dozen neighboring communities had gathered at the still-smoking hole that marked the site of the vanished crafts building. Within fifteen minutes, the disaster-trained crews had detected heavy crater. "How can an atom bomb go off in a nut house?" "I don't care if it was the size of a peanut," Thurgood screamed. "How standing around here. We don't know, but the fact remains that it WAS an atomic explosion." "Let's go over it once more, Dr. Crane.

They worked with oil and water paints "All I know is that you say this was a crafts building. O.K. So it was," "And I've got to find out how it happened." "Where's that girl you said was in charge of this place?" Outside the tent, a small army of military men and AEC technicians moved around the perimeter of the crater, scintillators in hand, examining every tiny scrap that might have been a part of the building at one time. expression. forward to catch her as she collapsed in a faint. At 4:00 p.m., the argument was still raging in the long, narrow staff edge of his chair at the head of a long table and pounded with his fist on the wooden surface, making Miss Abercrombie's chart book bounce with every beat. "It's ridiculous," Thurgood roared. "We'll all be the laughingstocks of the world if this ever gets out. An atomic bomb made out of clay. You are all nuts. You're in the right place, but count me out." At his left, Miss Abercrombie cringed deeper into her chair at the broadside. Down both sides of the long table, psychiatrists, physicists, strategists and radiologists sat in various stages of nerve-shattered weariness. "Miss Abercrombie," one of the physicists spoke up gently, "you say that "I'm positive that's all there was in it," Miss Abercrombie cried. There was a renewed buzz of conversation at the table and the senior AEC man present got heads together with the senior intelligence man. They "Are you crazy?" he screamed. "You want to get us all thrown into this filbert factory? Do you know what the newspapers would do to us if they ever got wind of the fact, that for one, tiny fraction of a second, anyone of us here entertained the notion that a paranoidal idiot with the IQ of an ape could make an atomic bomb out of kid's modeling clay? "They'd crucify us, that's what they'd do!" At 8:30 that night, Thaddeus Funston, swathed in an Army officer's Two military policemen and a brace of staff psychiatrists sworn to the night skies. the Nevada desert and two hours later, in a small hot, wooden shack miles up the barren desert wastelands, a cluster of scientists and military men huddled around a small wooden table. There was nothing on the table but a bowl of water and a great lump of "Now you're positive this is just about the same amount and the same brought us way out here just to see you make another atom bomb like the walked to the table and sat down.

The maze of clay strips grew and as Funston finished shaping the other half hemisphere of clay, she broke the tense silence. from the shack. There was a moment of hushed silence and then pandemonium burst. The For two hours they studied and gently probed the mass of child's clay range where Thaddeus and the psychiatrists waited inside a ring of stony-faced military policemen.

You come in here with an insane devices out of modeling clay and then has detonated them." In the distance, a white cloud began billowing up from the base of the Washington Monument, and with an ear-shattering, glass-splintering roar, the great shaft rose majestically from its base and vanished into space on a tail of flame.
