That was easy for Sherkaner Underhill to say. He didn't have to engineer the science into reality.

Underhill had stopped at an empty classroom; he peeked in at the blackboards. More gobbledegook. "You remember the cam-and-gear devices that Lands Command used in the War, to figure ballistic tables? We're making things like that with vacuum tubes and magnet cores. They're a million times faster than the cam gadgets, and we can input the numbers as symbol strings instead of vernier settings. Your physicists will love it." He chuckled. "You'll see, Hrunk. Except for the fact that the inventions are first-patented by our sponsors, you and Victory will have more than enough to keep you happy... ."

They continued up the long spiral stair. It opened finally onto an atrium near the top of the hill. There were higher hills around Princeton, but the view from here was spectacular enough, even in a cool drizzle. Unnerby could see a trimotor coming in at the airport. Tracts of late-phase development on the other side of the valley were the colors of wet granite and just-laid asphalt. Unnerby knew the company on that job. They had faith in the rumors that there would be power available to live long into the next Dark. What would Princeton be like if that were so? A city under the stars and hard vacuum, yet not asleep, and its deepnesses empty. The biggest risks would be late in the Waning Years, when people must decide whether to stock up for a conventional Dark, or gamble on what Hrunkner Unnerby's engineers thought they could do. His nightmares were not of failure, but of partial success.

"Daddy, Daddy!" Two five-year-olds careered into sight behind them. They were followed by two more cobblies, but these looked almost big enough to be in-phase. For more than ten years, Hrunkner Unnerby had done his best to overlook his boss's perversions: General Victory Smith was the best Intelligence chief he could imagine, probably even better than Strut Greenval. It shouldn't matter what her personal habits were. It had certainly never bothered him that she was born out-of-phase herself; that was something a person had no control over. But that she would start a family at the beginning of a New Sun, that she would damn her own children as she had been damned...And they aren't even all the same age.The two babies had hopped off Underhill's back. They scuttled across the grass and up the legs of their two oldest siblings. It was almost as if Smith and Underhill had deliberately set out to smear offal in the eyes of society's regard. This visit, so long avoided, was turning out to be just as bad as he'd feared.

The two oldest, both boys, hoisted the babies up, pretended for a moment to carry them like real fathers. They had no back fur, of course, and the babies slipped and slid down their carapaces. They grabbed hold of their brothers' jackets and scrambled back up, their baby laughter loud.

Underhill introduced the four to the sergeant. They all trooped across the soggy grass to the protection of an awning. This was the biggest play area that Unnerby had ever seen outside a schoolyard, but it was also very strange. A proper school went through discrete grades, targeting the current age of the pupils. The equipment in Underhill's play garden spanned a number of years. There were vertical gymnets, such as only a two-year-old could easily use. There were sandboxes, several huge dollhouses, and low play tables with picture books and games.

"Junior is the reason we didn't meet you and Mr. Unnerby downstairs, Dad." The twelve-year-old flicked a pointed hand in the direction of one of the five-year-olds—Victory Junior? "She wanted you up here, so we could show Mr. Unnerby all our toys."

Five-year-olds are not very good at hiding their feelings. Victory Junior still had her baby eyes. Even though baby eyes could turn a few degrees, there were only two of them; she had to face almost directly toward whatever she wanted to observe. In a way that could never be true of an adult, it was easy to see where Junior's attention was. Her two big eyes looked first at Underhill and Unnerby, then glanced toward her older brother. "Snitch!" she hissed at him. "You wanted them up here, too." She flicked her eating hands at him, and sidled close to Underhill. "I'm sorry, Daddy. I wanted to show my dollhouse, and Brent and Gokna still had their lessons to finish."

Underhill lifted his forearms to enclose her in a hug. "Well, we were going to come up here anyway." And to Unnerby: "I'm afraid the General has made rather a big thing of you, Hrunkner."

"Yeah, you're an Engineer!" said the other five-year-old—Gokna?

Whatever Junior's desires, Brent and Jirlib got to show off first. Their actual educational state was hard to estimate. The two had some kind of study curriculum, but were otherwise allowed to look into whatever they wished. Jirlib—the boy who had tattled on Junior—collected things. He seemed more deeply into fossils than any child Unnerby had ever seen. Jirlib had books from the Kingschool library that would have challenged adult students. He had a collection of diamond foraminiafera from trips with his parents down to Lands Command. And almost as much as his father, he was full of crazy theories. "We're not the first, you know. A hundred million years ago, just under the diamond strata, there are the Distorts of Khelm. Most scientists think they were dumb animals, but they weren't. They had a magic civilization, and I'm going to figure out how it worked." Actually, that was not new craziness, but Unnerby was a little surprised that Sherkaner let his children read Khelm's crank paleontology.

Brent, the other twelve-year-old, was more like the stereotype of an out-of-phase child: withdrawn, a little bit sullen, perhaps retarded. He didn't seem to know what to do with his hands and feet, and though he had plenty of eyes, he favored his foreview as though he were still much younger. Brent didn't seem to have any special interests except for what he called "Daddy's tests." He had bags of buildertoys, shiny metal dowels and connector hubs. Three or four of the tables were covered by elaborate dowel and connector structures. By clever variation of the number of dowels per hub, someone had constructed various curved surfaces for the child. "I've thought a lot about Daddy's tests. I'm getting better and better." He began fiddling with a large torus, breaking up the carefully built framework.

"Tests?" Unnerby waved a glare at Sherkaner. "What are you doing with these children?"

Underhill didn't seem to hear the anger in his voice. "Aren't children wonderful—I mean, when they aren't a pain in the ass. Watching a baby grow up, you can see the mechanisms of thought grow into place, stage by stage." He slipped a hand gently across his back, petting the two babies, who had returned to safe haven. "In some ways, these two are less intelligent than a jungle tarant. There are patterns of thought that just don't exist in babies. When I play with them, I can almost feel the barriers. But as the years pass, the minds grow; methods are added." Underhill walked along the play tables as he spoke. One of the five-year-olds—Gokna—danced half a pace in front of him, mimicking his gestures, even to the tremor. He stopped at a table covered with beautiful blown-glass bottles, a dozen shapes and tints. Several were filled with fruitwater and ice, as if for some bizarre lawn party. "But even the five-year-olds have mental blinders. They have good language skills, but they're still missing basic concepts—"

"And it's not just that we don't understand sex!" said Gokna.

For once, Underhill looked a little embarrassed. "She's heard this speech too many times, I fear. And by now her brothers have told her what to say when we play question games."

Gokna pulled on his leg. "Sit down and play. I want to show Mr. Unnerby what we do."
