'Sure thing, Ace. How about you, dear?'

Margrethe took the same, but medium rare.

'Steve?' the waitress inquired.

That'll be three beers - Coors - and three sirloin steaks, one rare, one medium rare, one medium. With the usual garbage. Baked potato, fried promises, whatever. The usual limp salad. Hot rolls. All the usual. Dessert later. Coffee.'

'Gotcha.'

'Wantcha to meet my friends. Maggie, this is Hazel. That's Alec, her husband.'

'You lucky man! Hi, Maggie; glad to know you. Sorry to see you in such company, though. Has Steve tried to sell you anything?'

'No,'

'Good. Don't buy anything, don't sign anything, don't bet with him. And be glad you're safely married; he's got wives in three states.'

'Four,' Steve corrected.

'Four now? Congratulations. Ladies' restroom is through the kitchen, Maggie; men go around behind.' She left moving fast, with a swish of her skirt.

'That's a fine broad,' Steve said. 'You know what they say about waitresses, especially in truckers' joints. Well, Hazel is probably the only hash-slinger on this highway who ain't sellin' it. Come on, Alec.' He got up and led me outdoors and around to the men's room. I followed him. By the time I understood what he had said, it was too late to resent his talking that way in a lady's presence. Then I was forced to admit that Margrethe had not resented it had simply treated it as information. As praise of Hazel, in fact. I think my greatest trouble with all these worrisome world changes had to do, not with economics, not with social behavior, not with technology, but simply with language, and the mores and taboos thereto.

Beer was waiting for us when we returned, and so was Margrethe, looking cool and refreshed.

Steve toasted us. 'Skoal!'

We echoed 'Skaal!' and I took a sip and then a lot more - just what I needed after a long day on a desert highway. My moral downfall in S.S. Konge Knut had included getting reacquainted with beer, something I had not touched since my days as an engineering student, and very little then - no money for vices. This was excellent beer, it seemed to me, but not as good as the Danish Tuborg served in the ship. Did you know that there is not one word against beer in the Bible? In fact the word 'beer' in the Bible means 'fountain'- or 'well'.

The steaks were delicious.'

Under the mellowing influence of beer and good food I found myself trying to explain to Steve how we happened to be down on our luck and accepting the charity of strangers... without actually saying anything. Presently Margrethe said to me, 'Alec. Tell him.'

'You think I should?'

'I think Steve is ent.i.tled to know. And I trust him.'

'Very well. Steve, we are strangers from another world.'

He neither laughed nor smiled; he just looked interested. Presently he said, 'Flying saucer?'

'No. I mean another universe, not just another planet. Although it seems like the same planet. I mean, Margrethe and I were in a state Called Arizona and a city called Nogales just earlier today. Then it changed. Nogales shrank down and nothing was quite the same. Arizona looked about the same, although I don't know this state very well.'

'Territory.'

'Excuse me?'

'Arizona is a territory, not a state. Statehood was voted down.'

'Oh. That's the way it was in my, world, too. Something about taxes. But we didn't come from my world. Nor from Marga's world. We came, from -'I stopped. 'I'm not telling this very well.' I looked across at Margrethe. 'Can you explain it?'

'I can't explain it,' she answered, because I don't understand it. But, Steve, it's true. I'm from one world, Alec is from another world, we've lived in still another world, and we were in yet again another world this morning. And now we are here. That is why we don't have any money. No, we do have money but it's not money of this world.'

Steve said, 'Could we take this one world at a time? I'm getting dizzy.'

I said, 'She left out two worlds.'

'No, dear - three. You may have forgotten the iceberg world.'

'No, I counted that. I - Excuse me, Steve. I'll try to take it one world at a time. But it isn't easy. This morning - We went into an ice cream parlor in Nogales because I wanted to buy Margrethe a hot fudge sundae. We sat down at a table, across from each other like right now, and that put me facing a set of traffic lights-'

'A set of what?'

'A set of traffic signal lights, red, green, and amber. That's how I spotted that we had changed worlds again. This world doesn't have signal lights, or at least I haven't seen any. Just traffic cops. But in the world we got up in this morning, instead of traffic cops, they do it with signal lights.'

Sounds like they do it with mirrors. What's this got to do with buying Maggie a hot fudge sundae?'

'That was because, when we were. shipwrecked and, floating around in the ocean, Margrethe wanted a hot fudge, sundae. This morning was my first chance to buy one for her. When the traffic lights disappeared, I knew we had changed worlds again - and that meant that my money wasn't any good. So I could not buy her a hot fudge sundae. And could not buy her dinner tonight. No money. No spendable money, I mean. You see?'

'I think I fell off three turns back. What happened to your money?'

'Oh.' I dug into my pocket, hauled out our carefully h.o.a.rded bus-fare money, picked out a twenty-dollar bill, handed it to Steve. 'Nothing happened to it. Look at this.'

He looked at it carefully. ' "Lawful money for all debts public and private." That sounds okay. But who's this joker with his picture on it? And when did they start.printing twenty-dollar treasury notes?'

'Never, in your world. I guess. The picture is of William Jennings Bryan, President of the United States from 1913 to 192l.'

'Not at Horace Mann School in Akron, he wasn't. Never heard of him.'

'In my school he was elected in 1896, not sixteen years later. And in Margrethe's world Mr Bryan was never president at all. Say! Margrethe! This just might be your world!'

'Why do you think so, dear?'

'Maybe, maybe not. As we came north out of Nogales I didn't notice a flying field or any signs concerning one. And I just remembered that I haven't heard or seen a jet plane all day long. Or any sort of a flying machine. Have you?'

,No. No, I haven't. But I haven't been thinking about them.' She added, 'I'm almost certain there haven't been any near us.'

There you have it! Or maybe this is my world. Steve, what's the situation on aeronautics here?'

'Arrow what?'

'Flying machines. Jet planes. Aeroplanes of any sort. And dirigibles - do you have dirigibles?'

'None of those things rings any bells with me. You're talking about flying, real flying, up in the air like a bird?'.

'Yes, yes!'

'No, of course not. Or do you mean balloons? I've seen a balloon.'
