And suddenly he tripped again and was hurled forward by his considerable momentum. But just at the moment he was about to hit the ground astoundingly hard he saw lying directly in front of him a small navy blue tote bag that he knew for a fact he had lost in the baggage retrieval system at the Athens airport some ten years previously in his personal time scale, and in his astonishment he missed the ground completely and bobbed off into the air with his brain singing.

What he was doing was this: he was flying. He glanced around him in surprise, but there could be no doubt that that was what he was doing. No part of him was touching the ground, and no part of him was even approaching it. He was simply floating there with boulders hurtling through the air around him.

He could now do something about that. Blinking with the noneffort of it he wafted higher into the air, and now the boulders were hurtling through the air beneath him.

He looked downward with intense curiosity. Between him and the shivering ground was now some thirty feet of empty air, empty, that is, if you discounted the boulders that didn’t stay in it for long, but bounded on downward in the iron grip of the law of gravity: the same law that seemed, all of a sudden, to have given Arthur a sabbatical.

It occurred to him almost instantly, with the instinctive correctness that self-preservation instills in the mind, that he mustn’t try to think about it, that if he did, the law of gravity would suddenly glance sharply in his direction and demand to know what the hell he thought he was doing up there, and all would suddenly be lost.

So he thought about tulips. It was difficult, but he did. He thought about the pleasing firm roundness of the bottom of tulips, he thought about the interesting variety of colors they came in, and wondered what proportion of the total number of tulips that grew, or had grown, on the Earth would be found within a radius of one mile from a windmill. After a while he got dangerously bored with this train of thought, felt the air slipping away beneath him, felt that he was drifting down into the paths of the bouncing boulders that he was trying so hard not to think about, so he thought about the Athens airport for a bit and that kept him usefully annoyed for about five minutes — at the end of which he was startled to discover that he was now floating about six hundred feet above the ground.

He wondered for a moment how he was going to get back down to it, but instantly shied away from that area of speculation again, and tried to look at the situation steadily.

He was flying. What was he going to do about it? He looked back down at the ground. He didn’t look at it hard, but did his best just to give it an idle glance, as it were, in passing. There were a couple of things he couldn’t help noticing. One was that the eruption of the mountain seemed now to have spent itself — there was a crater just a little way beneath the peak, presumably where the rock had caved in on top of the huge cavernous cathedral, the statue of himself and the sadly abused figure of Agrajag.

The other was his tote bag, the one he had lost at the Athens airport. It was sitting pertly on a piece of clear ground, surrounded by exhausted boulders but apparently hit by none of them. Why this should be he could not speculate, but since this mystery was completely overshadowed by the monstrous impossibility of the bag’s being there in the first place, it was not a speculation he really felt strong enough for anyway. The thing is, it was there.

He was faced with the fact that he was going to have to pick the thing up. Here he was, flying along six hundred feet above the surface of an alien planet, the name of which he couldn’t even remember. He could not ignore the plaintive posture of this tiny piece of what used to be his life, here, so many light-years from the pulverized remains of his home.

Furthermore, he realized, the bag, if it was still in the state in which he lost it, would contain a can that would have in it the only Greek olive oil still surviving in the Universe.

Slowly, carefully, inch by inch, he began to bob downward, swinging gently from side to side like a nervous sheet of paper feeling its way toward the ground.

It went well; he was feeling good. The air supported him, but let him through. Two minutes later he was hovering a mere two feet above the bag and was faced with some difficult decisions. He bobbed there lightly. He frowned, but again, as lightly as he could.

If he picked the bag up, could he carry it? Wouldn’t the extra weight pull him straight to the ground?

Wouldn’t the mere act of touching something on the ground suddenly discharge whatever mysterious force it was that was holding him in the air?

Wouldn’t he be better off just being sensible at this point and stepping out of the air, back onto the ground for a moment or two?

If he did, would he ever be able to fly again?

The sensation, when he allowed himself to be aware of it, was so quietly ecstatic that he could not bear the thought of losing it, perhaps forever. With this worry in mind he bobbed upward a little again, just to try the feel of it, the surprising and effortless movement of it. He bobbed, he floated. He tried a little swoop.

The swoop was terrific. With his arms spread out in front of him, his hair and dressing gown streaming out behind him, he dived down out of the sky, bellied along a body of air about two feet from the ground and swung back up again, catching himself at the top of the swing and holding. Just holding. He stayed there.

It was wonderful.

And that, he realized, was the way to pick up the bag. He would swoop down and catch hold of it just at the point of the upswing. He would carry it on up with him. He might wobble a bit, but he was certain that he could hold it.

He tried one or two more practice swoops, and they got better and better. The air on his face, the bounce and woof of his body, all combined to make him feel an intoxication of the spirit that he hadn’t felt since, since — well, as far as he could work out, since he was born. He drifted away on the breeze and surveyed the countryside, which was, he discovered, pretty nasty. It had a wasted, ravaged look. He decided not to look at it anymore. He would just pick up the bag and then … he didn’t know what he was going to do after he had picked up the bag. He decided he would just pick up the bag and see where things went from there.

He judged himself against the wind, pushed up against it and turned around. He didn’t realize it, but his body was willomying at this point.

He ducked down under the airstream, dipped — and dived.

The air threw itself past him; he thrilled through it. The ground wobbled uncertainly, straightened its ideas out and rose smoothly up to meet him, offering the bag, its cracked plastic handles up toward him.

Halfway down, there was a sudden dangerous moment when he could no longer believe he was doing this, and therefore very nearly wasn’t, but he recovered himself in time, skimmed over the ground, slipped an arm smoothly through the handles of the bag, and began to climb back up, couldn’t make it and all of a sudden collapsed, bruised, scratched and shaking on the stony ground.

He staggered instantly to his feet and swayed hopelessly around, swinging the bag around him in an agony of grief and disappointment.

His feet suddenly were stuck heavily to the ground in the way they always had been. His body seemed like an unwieldy sack of potatoes that reeled, stumbling, against the ground; his mind had all the lightness of a bag of lead.

He sagged and swayed and ached with giddiness. He tried hopelessly to run, but his legs were suddenly too weak. He tripped and flopped forward. At that moment he remembered that in the bag he was now carrying was not only a can of Greek olive oil but a duty-free allowance of retsina, and in the pleasurable shock of that realization he failed to notice for at least ten seconds that he was now flying again.
