Yes! Yes, he did remember! But there was still something wrong because--he couldn't think why. He remembered walking on a grassy meadow on a spring day. The grass was rich and luxuriant and the sun was hot copper in the sky. He was walking toward the top of a hill. Right at the top there was a single small, green tree. He was going to go up and lie down under that tree and look down in the valley at the meadow. And beside him there was--a presence. He remembered turning to look, and--nothing. There was nothing there. But the feeling of the presence next to him made him pleased, somehow. It was right. It was not menacing, like this afternoon, it was more--comforting. As the sound the Skipdrive made was comforting. It made him feel fine. But when he turned to look, there was nothing. He could not remember. What kind of presence? Like the ship? No, much smaller. Smaller even than himself. Compared to the ship, he was small, quite small. He was infinitely smaller than even planetary mass. And there were things on the ship that were smaller than he. But he couldn't quite place himself with assurance on the scale of size. He was larger than some things, like the bowl of soup, and he was smaller than other things, like planets. He must be of a sort of medium size. But closer to the bowl of soup than the planet. _A wife is a Martha._ He remembered thinking that just as the rockets had fired. It was in the song.... He whistled a few bars. _I had a good wife but I left her, oh, oh, oh, oh._ And it had something to do with the remembered--presence, when he was walking in the meadow. But what was a Martha? You can't define a nonsense word in terms of another nonsense word. Or perhaps, he thought ruefully, you can't define it any _other_ way. _A wife is a Martha. A wife is a Martha. A Martha is a wife._ Nothing. But he felt the headache coming on again. He went down to the galley again, and took the soup bowl with him. He put it in the washer, and rummaged around in the cabinets until he found the little white pills that helped his headaches. He took three of them before he went back up to the control room. He had to make some kind of plans for--for what? Escape? He didn't want to escape. He was home. He wanted to stay here. But he had to deal with the--things, somehow. He wondered if they could be killed. There was no way to tell. If you killed one you couldn't see its body. And he didn't have any weapons, at any rate. He would simply have to outsmart them. He wondered how smart they were. And how large. That would make a good deal of difference, how large they were. He went to the viewport and cracked the shutter, just a little. It was dark. He didn't want to go out in the dark, that was too much. It would be too much risk. He would wait until morning. In spite of the pills, the headache was getting worse, almost to the insane level it had been in the afternoon. He decided he'd better try to sleep. 3.
