After a dragging day, they were locked into their box--no one had a chance to gimmick the wall, for the giant were watching them closely--and shortly afterward a load of raw vegetables was dumped in. Watkins paced the floor after he had eaten, waiting for the sleep gas, determined to combat it if he could. When the drowsiness came, he walked faster. It didn't do any good. He knew he was sinking to the floor. Powerful stuff, he said to himself, very powerful st-- * * * * * Mrs. Full kept close to Calvin all through Sunday. They had been here since Thursday, all these men without women, and she knew there were men who had to have women frequently or they became vicious and could not be stopped by any thought of consequences. The Mexican seemed all right, but you never knew with a person from a Latin country. Another facet of the same problem was the fact that she and Calvin were supposed to be on their honeymoon. She faced it: she was frustrated. She wanted a honeymoon, no matter what sort of prison they were in. So after their first meal on Sunday, she asked Calvin to fix up a private apartment in their prison. With various materials, plastic blocks and the different sizes of slabs, and some screens of translucent fabric she had dug up in a corner, he made a walled-off compartment just large enough for two. Then one of the scientists looked in, saw what he was doing, and promptly knocked it down. Adam, who had been helping in the latter stages, squinted at the ceiling of the box. "You know, Mrs. Full, I think they can see us through that. If it's opaque to us, it still might be transparent to them; like a mirror, I mean, I've seen them at home, mirror on one side, window from the other. That'd explain the light we get in here. And if they want to observe us all the time, then this private cell of yours would make 'em mad." "But _it_ had no roof," she objected. "That's right." He shook his head. "Another theory gone poof." "I'll build it again," said Calvin stubbornly, and did so. This time the giants left it alone. He and Adam made a screen for the sand box too, and built a permanent grill on one side of the box. VIII By Tuesday they were all in a state of anxiety and scarcely-contained rage. Their surveillance was casual, often non-existent, yet not once had they been able to block the wall of their prison or open the great door of the laboratory. Circumstances, chance, fate, whatever you wanted to call it, something had stopped them every time.
