A glittering carpet shot out and about, whirling, spinning an insubstantial web that engulfed all space, and from it luminous shoots stabbed upward and branched into trees that sang with a music all their own.

Bayta sat inclosed in it. The music welled about her in rapid, lyrical flights. She reached out to touch a fragile tree and blossoming spicules floated downwards and faded, each with its clear, tiny tinkle.

The music crashed in twenty cymbals, and before her an area flamed up in a spout and cascaded down invisible steps into Bayta's lap, where it spilled over and flowed in rapid current, raising the fiery sparkle to her waist, while across her lap was a rainbow bridge and upon it the little figures-

A palace, and a garden, and tiny men and women on a bridge, stretching out as far as she could see, swimming through the stately swells of stringed music converging in upon her-

And then - there seemed a frightened pause, a hesitant, indrawn motion, a swift collapse. The colors fled, spun into a globe that shrank, and rose, and disappeared.

And it was merely dark again.

A heavy foot scratched for the pedal, reached it, and the light flooded in; the flat light of a prosy sun. Bayta blinked until the tears came, as though for the longing of what was gone. Ebling Mis was a podgy inertness with his eyes still round and his mouth still open.

Only Magnifico himself was alive, and he fondled his Visi-Sonor in a crooning ecstasy.

"My lady," he gasped, "it is indeed of an effect the most magical. It is of balance and response almost beyond hope in its delicacy and stability. On this, it would seem I could work wonders. How liked you my composition, my lady?"

"Was it yours?" breathed Bayta. "Your own?"

At her awe, his thin face turned a glowing red to the tip of his mighty nose. "My very own, my lady. The Mule liked it not, but often and often I have played it for my own amusement. It was once, in my youth, that I saw the palace - a gigantic place of jeweled riches that I saw from a distance at a time of high carnival. There were people of a splendor undreamed of - and magnificence more than ever I saw afterwards, even in the Mule's service. It is but a poor makeshift I have created, but my mind's poverty precludes more. I call it, 'The Memory of Heaven.'"

Now through the midst of the chatter, Mis shook himself to active life. "Here," he said, "here, Magnifico, would you like to do that same thing for others?"

For a moment, the clown drew back. "For others?" he quavered.

"For thousands," cried Mis, "in the great Halls of the Foundation. Would you like to be your own master, and honored by all, wealthy, and… and-" his imagination failed him. "And all that? Eh? What do you say?"

"But how may I be all that, mighty sir, for indeed I am but a poor clown ungiven to the great things of the world?"

The psychologist puffed out his lips, and passed the back of his hand across his brow. He said, "But your playing, man. The world is yours if you would play so for the mayor and his Trading Trusts. Wouldn't you like that?"

The clown glanced briefly at Bayta, "Would she stay with me?"

Bayta laughed, "Of course, silly. Would it be likely that I'd leave you now that you're on the point of becoming rich and famous?"

"It would all be yours," he replied earnestly, "and surely the wealth of Galaxy itself would be yours before I could repay my debt to your kindness."

"But," said Mis, casually, "if you would first help me-"

"What is that?"

The psychologist paused, and smiled, "A little surface probe that doesn't hurt. It wouldn't touch but the peel of your brain."

There was a flare of deadly fear in Magnifico's eyes. "Not a probe. I have seen it used. It drains the mind and leaves an empty skull. The Mule did use it upon traitors and let them wander mindless through the streets, until out of mercy, they were killed." He held up his hand to push Mis away.

"That was a psychic probe," explained Mis, patiently, "and even that would only harm a person when misused. This probe I have is a surface probe that wouldn't hurt a baby. "

"That's right, Magnifico," urged Bayta. "It's only to help beat the Mule and keep him far away. Once that's done, you and I will be rich and famous all our lives."

Magnifico held out a trembling hand, "Will you hold my hand, then?"

Bayta took it in both her own, and the clown watched the approach of the burnished terminal plates with large eyes.

Ebling Mis rested carelessly on the too-lavish chair in Mayor Indbur's private quarters, unregenerately unthankful for the condescension shown him and watched the small mayor's fidgeting unsympathetically. He tossed away a cigar stub and spat out a shred of tobacco.

"And, incidentally, if you want something for your next concert at Mallow Hall, Indbur," he said, "you can dump out those electronic gadgeteers into the sewers they came from and have this little freak play the Visi-Sonor for you. Indbur - it's out of this world."

Indbur said peevishly, "I did not call you here to listen to your lectures on music. What of the Mule? Tell me that. What of the Mule?"

"The Mule? Well, I'll tell you - I used a surface probe and got little. Can't use the psychic probe because the freak is scared blind of it, so that his resistance will probably blow his unprintable mental fuses as soon as contact is made. But this is what I've got, if you'll just stop tapping your fingernails-

"First place, de-stress the Mule's physical strength. He's probably strong, but most of the freak's fairy tales about it are probably considerably blown up by his own fearful memory, He wears queer glasses and his eyes kill, he evidently has mental powers."

"So much we had at the start," commented the mayor, sourly.

"Then the probe confirms it, and from there on I've been working mathematically."

"So? And how long will all this take? Your word-rattling will deafen me yet."

"About a month, I should say, and I may have something for you. And I may not, of course. But what of it? If this is all outside Seldon's plans, our chances are precious little, unprintable little."

Indbur whirled on the psychologist fiercely, "Now I have you, traitor. Lie! Say you're not one of these criminal rumormongers that are spreading defeatism and panic through the Foundation, and making my work doubly hard."

"I? I?" Mis gathered anger slowly.

Indbur swore at him, "Because by the dust-clouds of space, the Foundation will win - the Foundation must win."

"Despite the loss at Horleggor?"

"It was not a loss. You have swallowed that spreading lie, too? We were outnumbered and betreasoned-"

"By whom?" demanded Mis, contemptuously.

"By the lice-ridden democrats of the gutter," shouted Indbur back at him. "I have known for long that the fleet has been riddled by democratic cells. Most have been wiped out, but enough remain for the unexplained surrender of twenty ships in the thickest of the swarming fight. Enough to force an apparent defeat.

"For that matter, my rough-tongued, simple patriot and epitome of the primitive virtues, what are your own connections with the democrats?"

Ebling Mis shrugged it off, "You rave, do you know that? What of the retreat since, and the loss of half of Siwenna? Democrats again?"

"No. Not democrats," the little man smiled sharply. "We retreat - as the Foundation has always retreated under attack, until the inevitable march of history turns with us. Already, I see the outcome. Already, the so-called underground of the democrats has issued manifestoes swearing aid and allegiance to the Government. It could be a feint, a cover for a deeper treachery, but I make good use of it, and the propaganda distilled from it will have its effect, whatever the crawling traitors scheme. And better than that-"

"Even better than that, Indbur?"

"Judge for yourself. Two days ago, the so-called Association of Independent Traders declared war on the Mule, and the Foundation fleet is strengthened, at a stroke, by a thousand ships. You see, this Mule goes too far. He finds us divided and quarreling among ourselves and under the pressure of his attack we unite and grow strong. He must lose. It is inevitable - as always."

Mis still exuded skepticism, "Then you tell me that Seldon planned even for the fortuitous occurrence of a mutant."

"A mutant! I can't tell him from a human, nor could you but for the ravings of a rebel captain, some outland youngsters, and an addled juggler and clown. You forget the most conclusive evidence of all - your own."

"My own?" For just a moment, Mis was startled.

"Your own," sneered the mayor. "The Time Vault opens in nine weeks. What of that? It opens for a crisis. If this attack of the Mule is not the crisis, where is the 'real' one, the one the Vault is opening for? Answer me, you lardish ball."

The psychologist shrugged, "All tight. If it keeps you happy. Do me a favor, though. Just in case… just in case old Seldon makes his speech and it does go sour, suppose you let me attend the Grand Opening."

"All right. Get out of here. And stay out of my sight for nine weeks."

"With unprintable pleasure, you wizened horror," muttered Mis to himself as he left.

There was an atmosphere about the Time Vault that just missed definition in several directions at once. It was not one of decay, for it was well-lit and well-conditioned, with the color scheme of the walls lively, and the rows of fixed chairs comfortable and apparently designed for eternal use. It was not even ancient, for three centuries had left no obvious mark. There was certainly no effort at the creation of awe or reverence, for the appointments were simple and everyday - next door to bareness, in fact.

Yet after all the negatives were added and the sum disposed of, something was left - and that something centered about the glass cubicle that dominated half the room with its clear emptiness. Four times in three centuries, the living simulacrum of Hari Seldon himself had sat there and spoken. Twice he had spoken to no audience.

Through three centuries and nine generations, the old man who had seen the great days of universal empire projected himself - and still he understood more of the Galaxy of his great-ultra-great-grandchildren, than did those grandchildren themselves.
