What this means is that the suitcases have to be lashed down with the straps provided, and you and the operator have to hold on tight to the hand-grips placed here and there around the wall. Otherwise, you'd clonk your head on the ceiling.

But we got to level four at last, and off I went with my suitcases and the operator's directions. The suitcases weighed about half an ounce each out here, and I felt as though I weighed the same. Every time I raised a foot, I was sure I was about to go sailing into a wall. Local citizens eased by me, their feet occasionally touching the iron pavement as they soared along, and I gave them all dirty looks.

Level four was nothing but walls and windows. The iron floor went among these walls and windows in a straight straight line, bisecting other "streets" at perfect right angles, and the iron ceiling sixteen feet up was lined with a double row of fluorescent tubes. I was beginning to feel claustrophobic already.

The Chalmers Hotel—named for an Atronics vice-president—had received my advance registration, which was nice. I was shown to a second-floor room—nothing on level four had more than two stories—and was left to unpack my suitcases as best I may.

I had decided to spend a day or two at Atronics City before taking a scooter out to Ab Karpin's claim. Atronics City had been Karpin's and McCann's home base. All of McCann's premium payments had been mailed from here, and the normal mailing address for both of them was GPO Atronics City.

I wanted to know as much as possible about Ab Karpin before I went out to see him. And Atronics City seemed like the best place to get my information.

But not today. Today, my stomach was very unhappy, and my head was on sympathy strike. Today, I was going to spend my time exclusively in bed, trying not to float up to the ceiling.


The Mapping & Registry Office, it seemed to me the next day, was the best place to start. This was where prospectors filed their claims, but it was a lot more than that. The waiting room of M&R was the unofficial club of the asteroid prospectors. This is where they met with one another, talked together about the things that prospectors discuss, and made and dissolved their transient partnerships.

In this way, Karpin and McCann were unusual. They had maintained their partnership for fifteen years. That was about sixty times longer than most such arrangements lasted.
