Lathan Devers felt definitely uncomfortable, and vaguely resentful. He had received his own decoration and withstood with mute stoicism the turgid oratory of the mayor which accompanied the slip of crimson ribbon. That had ended his share of the ceremonies, but, naturally, formality forced him to remain. And it was formality, chiefly ?the type that couldn't allow him to yawn noisily or to swing a foot comfortably onto a chair seat ?that made him long to be in space, where he belonged.

The Siwennese delegation, with Ducem Barr a lionized member, signed the Convention, and Siwenna became the first province to pass directly from the Empire's political rule to the Foundation's economic one.

Five Imperial Ships of the Line ?captured when Siwenna rebelled behind the lines of the Empire's Border Fleet ?flashed overhead, huge and massive, detonating a roaring salute as they passed over the city.

Nothing but drinking, etiquette, and small talk now.

A voice called him. It was Forell; the man who, Devers realized coldly, could buy twenty of him with a morning's profits ?but a Forell who now crooked a finger at him with genial condescension.

He stepped out upon the balcony into the cool night wind, and bowed properly, while scowling into his bristling beard. Barr was there, too; smiling. He said, "Devers, you'll have to come to my rescue. I'm being accused of modesty, a horrible and thoroughly unnatural crime."

"Devers," Forell removed the fat cigar from the side of his mouth when he spoke, "Lord Barr claims that your trip to Cleon's capital had nothing to do with the recall of Riose."

"Nothing at all, sir." Devers was curt. "We never saw the Emperor. The reports we picked up on our way back concerning the trial, showed it up to be the purest frameup. There was a mess of rigmarole about the general being tied up with subversive interests at the court."

"And he was innocent?"

"Riose?" interposed Barr. "Yes! By the Galaxy, yes. Brodrig was a traitor on general principles but was never guilty of the specific accusations brought against him. It was a judicial farce; but a necessary one, a predictable one, an inevitable one."

"By psychohistorical necessity, I presume." Forell rolled the phrase sonorously with the humorous ease of long familiarity.

"Exactly." Barr grew serious. "It never penetrated earlier, but once it was over and I could ... well ... look at the answers in the back of the book, the problem became simple. We can see, now, that the social background of the Empire makes wars of conquest impossible for it. Under weak Emperors, it is tom apart by generals competing for a worthless and surely death-bringing throne. Under strong Emperors, the Empire is frozen into a paralytic rigor in which disintegration apparently ceases for the moment, but only at the sacrifice of all possible growth."

Forell growled bluntly through strong puffs, "You're not clear, Lord Barr."

Barr smiled slowly. "I suppose so. It's the difficulty of not being trained in psychohistory. Words are a pretty fuzzy substitute for mathematical equations. But let's see now?

Barr considered, while Forell relaxed, back to railing, and Devers looked into the velvet sky and thought wonderingly of Trantor.

Then Barr said, "You see, sir, you ?and Devers ?and everyone no doubt, had the idea that beating the Empire meant first prying apart the Emperor and his general. You, and Devers, and everyone else were right ?right all the time, as far as the principle of internal disunion was concerned.

"You were wrong, however, in thinking that this internal split was something to be brought about by individual acts, by inspirations of the moment. You tried bribery and lies. You appealed to ambition and to fear. But you got nothing for all your pains. In fact, appearances were worse after each attempt.

"And through all this wild threshing up of tiny ripples, the Seldon tidal wave continued onward, quietly ?but quite irresistibly............
