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. Circ.u.mstances, chance, fate, whatever you wanted to call it, something had stopped them every time.

There were three giants in the lab today. Sometimes there would be one of them, sometimes as many as five; but always there would be the one who had first removed them from the box, who seemed to be the head scientist, giving orders, bullying the others in the queer emotional way of these creatures. Today there were three. As usual, when they had let the humans out, the lab was clean and orderly. The sloppy scientists had very efficient janitors, thought Adam. By this time the place was a shambles.

Out in the lab, there rose the honking sound of pain and anger--some of the noises they made, especially the commands, were recognizable now to the people--and a sharp slap. Then Mrs. Full hurried into the box, carrying a number of two-foot-square slabs under her arm.

"What happened, ma'am?"

"h.e.l.lo, Adam. The criminal Watkins played a few bars of a real song on that device, and the brutes. .h.i.t him." She laid down the slabs. "Our harmonies enrage them, I think perhaps cause them actual pain. They held the sides of their heads where ears ought to be, and shook themselves and made those hideous noises."

"They hit me when I sang the other day," said Adam, "remember?"

"That's right. Look here." She sat down, pulled one of the thick slabs onto her lap. "I found these under a shelf out there. One of the creatures knocked them off and I picked them up. I wondered why they had been up there, when so many stacks of them just sit around on the floor."

"I never saw any like these, ma'am. They have that little ridge on the edge there, and the border of different colored stuff around 'em."

"Watch what happens when I push the ridge upward, Adam. It's like an automatic b.u.t.ton." She pressed it and the slab, at first gay orange, turned pale blue; on it appeared three lines of squiggly characters, like a cross between Arabic writing and Egyptian hieroglyphics.

"A magic slate," said Adam. "That's neat!"

"You haven't seen anything yet," she told him, and pushed the ridge again. The writing disappeared, and out of the slab leered a bull gorilla, paws on chest, eyeing Adam with beady, ridge-browed malevolence. It took a second for sanity to convince him that it was only a picture: three-dimensional, on a two-dimensional sheet of plastic, but so real he half-expected the beast to charge out at him.

"What about that?" she asked.

He hit his thigh with a fist. It was a photograph, he imagined, but made by an illusory process so far ahead of anything humanity could produce that it seemed he might glimpse whatever was behind the gorilla if he put his eyes down to the side of the slate. "Gosh!" he said, feeling it a little nave but afraid to swear in front of her. "Isn't that something!"

"It's a book," she said, "an alb.u.m of photographs. Look here."

The next picture was an equally miraculous one of half a dozen monkeys sitting on a tree trunk. Adam looked at it, then at the farthest trunk in their box of a room. Undeniably it was the same one.

Under the picture was a line of squiggles that probably spelled out the scientists' equivalent of "monkeys."

"They were here, in this place," said Adam. "The giants must have experimented on them too." He turned his eyes up to the woman and saw that she was white and drawn. "What happened to them?" he asked. "There aren't any monkeys here now."

"Exactly," she said. She put on the next picture, and after a moment the next.

Dogs greeted his eyes, so real he could almost hear them pant; a cow gazed stolidly at him; a cheetah sat on a mound of straw with clown's head c.o.c.ked inquisitively; two c.o.c.katoos perched in rigid still life on the silver rod of the prison box.

"What happened to them?" he asked again.

"The experiments ended," she said.

Then there flashed out a thing like a blue sponge with legs, a thing which sat in the cat's-cradle they had speculated so much about. From its center two ruby eyes blazed with three-dimensional fire. _That_ never came from Earth! Mars or Venus could have produced it, maybe, or a planet so far from Earth that it bore no name. He said as much, his voice quavering.

She stared at him. Moistening her lips, she said, "If that was here, in this box, then _where are we_?"

He shook his head. He could not even guess. "What's next?"

The last picture in the slate was a group portrait of himself, the Fulls, Summersby, Watkins, and Porfirio Villa.

When was that taken? They were sitting in a circle on the straw, eating something. Peering closely, he thought it must be the vegetables, for there was a small heap of round things next to Calvin Full which were probably buckeyes. Sunday night, then.

"They must have taken it through the food panel," he said. "Are there any more pictures?"

"That's all. I don't know what's in the other ones yet."

Calvin came in. She handed him the first "book" and showed him how to operate it. He flipped through it and when he came to the monstrosity in the web his eyes widened. "What is it?" he asked, in the hard tw.a.n.g of his region.

"A guinea pig, like all the others including us," his wife said.

"The tree trunks are explained now," said Adam, half to himself. "The sand box, too. That isn't a very scientific-looking treatise, but I guess it's more of a memento, a record of us all." He raised his brows in a facial shrug. "Us and the monkeys," he said. "Gosh!"

She took the next big slate on her lap. It was lavender. The first few pages to appear were covered with the curious writing, very large and only a few words to a page. Then came pictures of many things, not photographs but drawings and paintings in vivid color, and the things could in no way be linked to science. There were portraits of the tall creatures themselves, in various settings, some in labs like this one, some outdoors in a landscape that was predominantly scarlet and green; there were group scenes in which they ate odd-looking foods and walked down blue pathways and examined strange pets and familiar animals. Under each picture was a short grouping of squiggles, marks, scribbles, etc.

"Can that be a science book?" asked Cal, leaning over his wife's shoulder. The beings were pictured as simply as possible, in no minute detail whatever, and their activities were of the dullest and most prosaic sort.

This pattern was followed through page after page--a picture (some of them were of things so alien they could not be placed by either the Fulls or himself), a single character, then a short word and another, long or short as the case might be. After a dozen of them had flashed on and off Adam noticed that the large character was always repeated at the beginning of the last word.

When he realized what it meant, the whole business clicked into focus.

The whole d.a.m.ned deal, the lab and the scientists and the experiments and the meaning of the four magic slates, and everything. There was no particular reason why this last slate should have done it, for it was no more suggestive than many other things that he had seen; it was simply the last piece of evidence, the final push that sent him headlong into terrible knowledge.

Carefully, desperately, he went over it all in his mind, while the Fulls spoke in low tones.

_G.o.d_, he thought, _oh, G.o.d!_ He was shivering now. He was more terrified than he had ever been before. His tongue felt thick.

The punishments, the high stool and the arbitrary cuffs and swats; the gadgets, the mazes, the puzzles; were they all a part of the conditioning to neurosis of a scientific experiment? They were not.
