Humphrey Fownes took out the dust jacket he'd found in the library. He held it up and carefully compared the spinning cloud in his bedroom with the illustration. The cloud rose and spun, assuming the identical shape of the illustration.

"It's a twister," he said softly. "A Kansas twister!"

"What," MacBride asked, his bravado slipping away again, "what ... is a twister?"

The twister roared and moved out of the bedroom, out over the rear of the house toward the side of the dome. "It says here," Fownes shouted over the roaring, "that Dorothy traveled from Kansas to Oz in a twister and that ... and that Oz is a wonderful and mysterious land beyond the confines of everyday living."

MacBride's eyes and mouth were great zeros.

"Is there something I can turn?" Lanfierre asked.

Huge chunks of glass began to fall around them.

"Fownes!" MacBride shouted. "This is a direct order! Make it go back!"

But Fownes had already begun to run on toward the next house, dodging mountainous puffs of glass as he went. "Mrs. Deshazaway!" he shouted. "Yoo-hoo, Mrs. Deshazaway!"

The dome weevils were going berserk trying to keep up with the precipitation. They whirred back and forth at frightful speed, then, emptied of molten glass, rushed to the Trough which they quickly emptied and then rushed about empty-handed. "Yoo-hoo!" he yelled, running. The artificial sun vanished behind the mushrooming twister. Optimum temperature collapsed. "Mrs. Deshazaway! Agnes, will you marry me? Yoo-hoo!"
