"Now turn them so that they can see the flowers and books."
Turned, the babies at once fell silent, then began to crawl towards those clusters of sleek colours, those shapes so gay and brilliant on the white pages. As they approached, the sun came out of a momentary eclipse behind a cloud. The roses flamed up as though with a sudden passion from within; a new and profound significance seemed to suffuse the shining pages of the books. From the ranks of the crawling babies came little squeals of excitement, gurgles and twitterings of pleasure.
The Director rubbed his hands. "Excellent!" he said. "It might almost have been done on purpose."
The swiftest crawlers were already at their goal. Small hands reached out uncertainly, touched, grasped, unpetaling the transfigured roses, crumpling the illuminated pages of the books. The Director waited until all were happily busy. Then, "Watch carefully," he said. And, lifting his hand, he gave the signal.
The Head Nurse, who was standing by a switchboard at the other end of the room, pressed down a little lever.
There was a violent explosion. Shriller and ever shriller, a siren shrieked. Alarm bells maddeningly sounded.
The children started, screamed; their faces were distorted with terror.
"And now," the Director shouted (for the noise was deafening), "now we proceed to rub in the lesson with a mild electric shock."
He waved his hand again, and the Head Nurse pressed a second lever. The screaming of the babies suddenly changed its tone. There was something desperate, almost insane, about the sharp spasmodic yelps to which they now gave utterance. Their little bodies twitched and stiffened; their limbs moved jerkily as if to the tug of unseen wires.
"We can electrify that whole strip of floor," bawled the Director in explanation. "But that's enough," he signalled to the nurse.
The explosions ceased, the bells stopped ringing, the shriek of the siren died down from tone to tone into silence. The stiffly twitching bodies relaxed, and what had become the sob and yelp of infant maniacs broadened out once more into a normal howl of ordinary terror.
"Offer them the flowers and the books again."
