Illustrated by Freas Miss Abercrombie, the manual therapist patted the old man on the shoulder. The oldster in the stained convalescent suit gave her a quick, shy smile and went back to his aimless smearing in the finger paints. Miss Abercrombie smoothed her smock down over trim hips and surveyed the other patients working at the long tables in the hospital's arts and crafts shop. Two muscular and bored attendants in spotless whites, lounged beside the locked door and chatted idly about the Dodgers' prospects for the pennant. Through the barred windows of the workshop, rolling green hills were seen, their tree-studded flanks making a pleasant setting for the mental institution. The crafts building was a good mile away from the main buildings of the hospital and the hills blocked the view of the austere complex of buildings that housed the main wards. The therapist strolled down the line of tables, pausing to give a word 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. "You've been coming along famously and you must remember to answer when someone talks to you. Thaddeus Funston continued to mold the clay bits and put them in place. I thought you said an 'atom bomb.'" Safely behind the patient's back, Miss Abercrombie smiled ever so slightly. That shows real creative thought. A tall, blond patient with a flowing mustache, put one more dab of paint on his canvas and stood back to survey the meaningless smears. At the clay table, Funston feverishly fabricated the last odd-shaped bit of clay and slapped it into place. The patients lined up at the door, waiting for the walk back across the green hills to the main hospital. Miss Abercrombie gazed around the cluttered room and picked up her chart book of patient progress. Moving slowly down the line of benches, she made short, precise notes on the day's work accomplished by each patient. At the clay table, she carefully lifted the top half of the clay ball and stared thoughtfully at the jumbled maze of clay strips laced through the lower hemisphere.
