"I don't know."

Another scientist wandered over and sat down beside the first. Shortly they seemed to get in each other's way, and there was a lot of shoving and squawking. At last one of them hit the other in the face with an open hand. Then they were rolling on the floor, snatching at one another's hair and pummeling the big bodies and heads with those gargantuan fists. It sounded like a brawl between elephants. Watkins swiveled round to watch. Mrs. Full said to someone—Watkins heard her distinctly in a lull in the ruckus—"If these are scientists, what are the common people like?" For the first time that day he grinned. He had stopped playing the organ. The other scientists had gathered around the fight and were uttering strange cries, like wild geese honking. Cheering them on? he wondered.

Adam came over. "Mr. Watkins," he said, "could we have been wrong about them? Do you think a scientist would act like that?"

"They sure seem to be a quarrelsome race, Adam," he said, "they're not noticing what we do. Suppose you go look for a way out."

"We want to get away as soon as we can," nodded the boy. "Dangerous around here!" He ran down the hall.

The giants arose and straightened their clothing. They had patched up their argument in the midst of fighting over it. The leader walked toward a tall device of pipes and boards and steps, motioning Mrs. Full to follow.

Apparently Watkins had been forgotten. He took his briefcase off his lap, where he had held it all the time he played, and dropped it to the floor. Then he hung by his hands and let go. He picked up the case and went to investigate the room.

Before he had done more than glimpse the enormous door, he was picked up kitten-fashion by a scientist, who carried him off, dangling and swearing, to another infernal machine.

For a couple of hours they were put through paces, all of them; sometimes one man would be working a gadget while all the scientists and humans watched him, at other periods they would each be hard at work doing something the result of which they had no conception of.
