"Not entirely so! I merely wished to make a point. It is all a matter of objective. You have seen how older children are developing their psi talents in our classes. Your wife may have shown us how to begin training at a much earlier age, when training is most important."

"Still, I should think you would require more substantiation, some further testing, to support Miss Poteil's little experiment."

"Of course. Do you have any suggestions, Dr. Brill?"

Once more Lucifer found himself backed toward a corner. Only this time he did not try to escape. The challenge intrigued him, in spite of his determination not to become involved with this nonsense. A controlled experiment was quite a different thing....

"I might have," he replied, with an effort to be casual. He plucked at his mustache. "But you must grant that a valid basis for experimentation cannot be improvised on the spur of the moment."

"Improvise at your leisure, Dr. Brill."

Nina was sent off to continue orientation work with Dr. Thame. Lucifer was given a small cubicle near Huth's office. It consisted of little more than a desk, a stool, three bare walls and a floor to ceiling window through which an orange rim of the planet's great sun was now shining mistily.

Lucifer scribbled notes, drew crude diagrams, tore them up and started all over again. Spots of color flushed his cheeks. Though he would not have made the admission, he hadn't enjoyed himself so much in fifteen years. He didn't even notice when a new squall rustled across the wet jungle, blotting out the sun and drumming against the window.

Huth came in with the attendant who brought lunch.

"How many children are there here now?" Lucifer asked crisply.
