"Don't you recognize it? Baked baby gregarian."

It took a couple of seconds for Don to place in his mind just what a gregarian was. As a small child he had seen hundreds of the little satyr-like bipeds-faunas gregariaus veneris Smythii-but he did not at first associate the common commercial name with the friendly, silly creatures he and his playmates, along with all other Venus colonials, had always called "move-overs" because of their chronic habit of crowding up against one, shouldering, nuzzling, sitting on one's feet, and in other ways displaying their insatiable appetite for physical affection.

Eat a baby, move-over? He felt like a cannibal and for the second time in one day started to behave like a groundhog in space. He gulped and controlled himself but could not touch another bite.

He looked back at the stage. Venusberg disappeared, giving way to a tired-eyed man who kept up a rapid fire of jokes while juggling flaming torches. Don was not amused; he let his gaze wander around the room. Three tables away a man met his eyes, then looked casually away. Don thought about it, then looked the man over carefully and decided that he recognized him. "Dr. Jefferson?"

"Yes, Don?"

"Do you happen to know a Venus dragon who calls himself `Sir Isaac Newton'?" Don added the whistled version of the Venerian's true name.

"Don't!" the older man said sharply.

"Don't what?"

"Don't advertise your background unnecessarily, not at this time. Why do you ask about this, uh, `Sir Isaac Newton'?" He kept his voice low with his lips barely moving.

Donald told him about the casual meeting at Gary Station. "When I got through I was dead sure that a security cop was watching me. And now that same man is sitting over there, only now he's not in uniform."

"Are you sure?"

"I think I'm sure."

"Mmm... you might be mistaken. Or he might simply be here in his off hours-though a security policeman should not be, not on his pay. See here, pay no further attention to him and don't speak of him again. And don't speak of that dragon, nor of anything else Venetian. Just appear to be having a good time. But pay careful attention to anything I say."

Don tried to carry out the instructions, but it was hard to keep his mind on gaiety. Even when the dancers reappeared he felt himself wanting to turn and stare at the man who had dampened the party. The plate of baked gregarian was removed and Dr. Jefferson ordered something for him called a "Mount Etna." It was actually shaped like a volcano and a plume of steam came out of the tip. He dipped a spoon into it, found that it was fire and ice, assaulting his palate with conflicting sensations. He wondered how anyone could eat it. Out of politeness he cautiously tried another bite. Presently he found that he had eaten all of it and was sorry there was not more.

At the break in the stage acts Don tried to ask Dr. Jefferson what he really thought about the war scare. The; doctor firmly turned the talk around to his parents' work and branched out to the past and future of the System. "Don't fret yourself about the present, son. Troubles, merely troubles-necessary preliminaries to the consolidation of the System. In five hundred years the historians will hardly notice it. There will be the Second Empire-six planets by then."

"Six? You don't honestly think well ever be able to do anything with Jupiter and Saturn? Oh-you mean the Jovian moons."

"No, I mean six primary planets. We'll move Pluto and Neptune in close by the fire and we'll drag Mercury back and let it cool off."

The idea of moving planets startled Don. It sounded wildly impossible, but he let it rest, since his host was a man who maintained that everything and anything was possible. "The race needs a lot of room," Dr. Jefferson went on. "After all, Mars and Venus have their own intelligent races; we can't crowd them much more without genocide-and it's not dead certain which way the genocide would work, even with the Martians. But the reconstruction of this system is just engineering - nothing to what else we'll do. Half a millennium from now there will be more Earth-humans outside this system than in it; we'll be swarming around every G-type star in this neighborhood. Do you know what I would do if I were your age, Don? I'd get me a berth in the Pathfinder."

Don nodded. "I'd like that." The Pathfinder, star ship intended for a one-way trip, had been building on, and near, Luna since before he was born. Soon she would go. All or nearly all of Don's generation had at least dreamed about leaving with her.

"Of course," added his host, "you would have to have a bride." He pointed to the stage which was again filling. "Take that blonde down there. She's a likely looking lassie-healthy at least."

Don smiled and felt worldly. "She might not hanker after pioneering. She looks happy as she is."

"Can't tell till you ask her. Here." Dr. Jefferson summoned the maitre d'hotel; money changed hands. Presently the blonde came to their table but did not sit down. She was a tom-tom singer and she proceeded to boom into Don's ears, with the help of the orchestra, sentiments that would have embarrassed him even if expressed privately. He ceased to feel worldly, felt quite warm in the face instead and confirmed his resolution not to take this female to the stars. Nevertheless he enjoyed it.

The stage was just clearing when the lights blinked once and the sound system again brayed forth: "Space raid warning! Space raid warning!" All lights went out.

For an infinitely long moment there was utter blackness and silence without even the muted whir of the blowers. Then a tiny light appeared in the middle of the stage, illuminating the features of the starring comic. He drawled in an intentionally ridiculous nasal voice, "The next sound you hear will be... The Tromp of Doom!" He giggled and went on briskly, "Just sit quiet, folks, and hang on to your money-some of the help are relatives of the management. This is just a drill. Anyhow, we have a hundred feet of concrete overhead-and a darn sight thicker mortgage. Now, to get you into the mood for the next act which is mine, the next round of drinks is on the house." He leaned forward and called out, "Gertie! Drag up that stuff we couldn't unload New Year's Eve."

Don felt the tension ease around the room and he himself relaxed. He was doubly startled when a hand closed around his wrist. "Quiet!" whispered Dr. Jefferson into his ear.

Don let himself be led away in the darkness. The doctor apparently knew, or remembered, the layout; they got out of the room without bumping into tables and with only one unimportant brush with someone in the dark. They seemed to be going down a long hall, black as the inside of coal, then turned a corner and stopped.

"But you can't go out sir," Don heard a voice say. Dr. Jefferson spoke quietly, his words too low to catch. Something rustled; they moved forward again, through a doorway, and turned left.

They proceeded along this tunnel-Don felt sure that it was the public tunnel just outside the restaurant though it seemed to have turned ninety degrees in the dark. Dr. Jefferson still dragged him along by the wrist without speaking. They turned again and went down steps.

There were other people about, though not many. Once someone grabbed Don in the dark; he struck out wildly, smashed his fist into something flabby and heard a muffled grunt. The doctor merely pulled him along the faster.

The doctor stopped at last, seemed to be feeling around in the dark. There came a feminine squeal out of the blackness. The doctor drew back hastily and moved on a few feet, stopped again. "Here," he said at last. "Climb in." He pulled Don forward and placed his hand on something; Don felt around and decided that it was a parked autocab, its top open. He climbed in and Dr. Jefferson got in behind, closing the top after him. "Now we can talk," he said calmly. "Someone beat us to that first one. But we can't go anywhere until the power comes on again."
