"Come on! Let's see who can send his highest!" And I took all the new atoms I was hiding and flung them into space. At first they seemed to scatter, then they thickened together into a kind of light cloud, and the cloud swelled and swelled, and inside it some incandescent condensations were formed, and they whirled and whirled and at a certain point became a spiral of constellations never seen before, a spiral that poised, opening in a gust, then sped away as I held on to its tail and ran after it. But now I wasn't the one who made the galaxy fly, it was the galaxy that was lifting me aloft, clinging to its tail; I mean, there wasn't any height or depth now but only space, widening, and the galaxy in its midst, also opening wide, and me hanging there, making faces at Pfwfp, who was already thousands of light-years away.

Pfwfp, at my first move, had promptly dug out all his hoard, hurling it with a balanced movement as if he expected to see the coils of an endless galaxy open in the sky. But instead, nothing happened. There was a sizzling sound of radiations, a messy flash, then everything died out at once.

"Is that the best you can do?" I shouted at Pfwfp, who was yelling curses at me, green with rage:

"I'll show you, Qfwfq, you pig!"

But in the meanwhile my galaxy and I were flying among thousands of other galaxies, and mine was the newest, the envy of the whole firmament, blazing as it was with young hydrogen and the youngest carbon and newborn beryllium. The old galaxies fled us, filled with jealousy, and we, prancing and haughty, avoided them, so antiquated and ponderous to look at. As that reciprocal flight developed, we sailed across spaces that became more and more rarefied and empty: and then I saw something appear in the midst of the void, like uncertain bursts of light. These were new galaxies, formed by matter just born, galaxies even newer than mine. Soon space became filled again, and dense, like a vineyard just before vintage time, and we flew on, escaping from one another, my galaxy fleeing the younger ones as it had the older, and young and old fleeing us. And we advanced to fly through empty skies, and these skies also became peopled, and so on and on.

In one of these propagations, I heard: "Qfwfq, you'll pay for this now, you traitor!" and I saw a brand-new galaxy flying on our trail, and there leaning forward from the very tip of the spiral, yelling threats and insults at me, was my old playmate Pfwfp.

The chase began. Where space rose, Pfwfp's galaxy, young and agile, gained ground, but on the descents, my heavier galaxy plunged ahead again.

In any kind of race there's a secret: it's all in how you take the curves. Pfwfp's galaxy tended to narrow them, mine to swing out. And as it kept broadening the curves, we were finally flung beyond the edge of space, with Pfwfp after us. We kept up the pursuit, using the system one always uses in such circumstances, that is, creating space before us as we went forward.

So there I was, with nothingness in front of me, and that nasty-faced Pfwfp after me: an unpleasant sight either way. In any case, I preferred to look ahead, and what did I see? Pfwfp, whom my eyes had just left behind me, was speeding on his galaxy directly in front of me. "Ah!" I cried, "now it's my turn to chase you!"

"What?" Pfwfp said, from before me or behind me, I'm not really sure which, "I'm the one who's chasing you!"

I turned around: there was Pfwfp, still at my heels. I looked ahead again: and he was there, racing off with his back turned to me. But as I looked more closely, I saw that in front of this galaxy of his that was preceding me there was another, and that other galaxy was mine, because there I was on it, unmistakable even though seen from behind. And I turned toward the Pfwfp following me and narrowed my eyes: I saw that his galaxy was being chased by another, mine, with me on top of it, turning at that same time to look back.

And so after every Qfwfq there was a Pfwfp, and after every Pfwfp a Qfwfq, and every Pfwfp was chasing a Qfwfq, who was pursuing him and vice versa. Our distances grew a bit shorter or a bit longer, but now it was clear that one would never overtake the other, nor the other overtake one. We had lost all pleasure in this game of chase, and we weren't children any more for that matter, but now there was nothing else we could do.

The first vertebrates who, in the Carboniferous period, abandoned aquatic life for terrestrial, descended from the osseous, pulmonate fish whose fins were capable of rotation beneath their bodies and thus could be used as paws on the earth.

By then it was clear that the water period was coming to an end, – old Qfwfq recalled, - those who decided to make the great move were growing more and more numerous, there wasn't a family that didn't have some loved one up on dry land, and everybody told fabulous tales of the things that could be done there, and they called back to their relatives to join them. There was no holding the young fish; they slapped their fins on the muddy banks to see if they would work as paws, as the more talented ones had already discovered. But just at that time the differences among us were becoming accentuated: there might be a family that had been living on land, say, for several generations, whose young people acted in a way that wasn't even amphibious but almost reptilian already; and there were others who lingered, still living like fish, those who, in fact, became even more fishy than they had been before.

Our family, I must say, including grandparents, was all up on the shore, padding about as if we had never known how to do anything else. If it hadn't been for the obstinacy of our great-uncle N'ba N'ga, we would have long since lost all contact with the aquatic world.

Yes, we had a great-uncle who was a fish, on my paternal grandmother's side, to be precise, of the Coelacanthus family of the Devonian period (the fresh-water branch: who are, for that matter, cousins of the others – but I don't want to go into all these questions of kinship, nobody can ever follow them anyhow). So as I was saying, this great-uncle lived in certain muddy shallows, among the roots of some protoconifers, in that inlet of the lagoon where all our ancestors had been born. He never stirred from there: at any season of the year all we had to do was push ourselves over the softer layers of vegetation until we could feel ourselves sinking into the dampness, and there below, a few palms' lengths from the edge, we could see the column of little bubbles he sent up, breathing heavily the way old folk do, or the little cloud of mud scraped up by his sharp snout, always rummaging around, more out of habit than out of the need to hunt for anything.

"Uncle N'ba N'ga! We've come to pay you a visit! Were you expecting us?" we would shout, slapping our paws and tails in the water to attract his attention. "We've brought you some insects that grow where we live! Uncle N'ba N'ga! Have you ever seen such fat cockroaches? Taste one and see if you like it "

"You can clean those revolting warts you've got with your stinking cockroaches!" Our great-uncle's answer was always some remark of this sort, or perhaps even ruder: this is how he welcomed us every time, but we paid no attention because we knew he would mellow after a little while, accept our presents gladly, and converse in politer tones.

"What do you mean, Uncle? Warts? When did you ever see any warts on us?"

This business about warts was a widespread prejudice among the old fish: a notion that, from living on dry land, we would develop warts all over our bodies, exuding liquid matter: this was true enough for the toads, but we had nothing in common with them; on the contrary, our skin, smooth and slippery, was such as no fish had ever had; and our great-uncle knew this perfectly well, but he still couldn't stop larding his talk with all the slanders and intolerance he had grown up in the midst of.
