“What are you doing?” Ann said, sounding annoyed.

Sax explained, and she listened in stony silence. He didn’t know what she might be thinking. That the world was somewhat explicable — he always found that a comfort. But Ann… well, it could be as simple as seasickness. Or something from her past, distracting her; Sax had found in the weeks since the experiment at Underhill that he was often distracted by some past incident, rising unbidden from a great bulk of them in his mind. Involuntary memory. And for Ann, that might include negative incidents of one kind or another; Michel had said she had been mistreated as a child. It still seemed to Sax too shocking to believe. On Earth men had abused women; on Mars, never. Was that true? Sax did not know for sure, but he felt it was true. This was what it meant to live in a just and rational society, this was one of the main reasons it was a good thing, a value. Possibly Ann would know more about the reality of the situation these days. But he did not feel comfortable asking her. It was clearly contraindicated.

“You’re awfully quiet,” she said.

“Enjoying the view,” he said quickly. Perhaps he had better talk about wave mechanics after all. He explained the groundswell, the cross chop, the negative and positive interference patterns that could result. But then he said, “Did you remember much about Earth, during the Underhill experiment?”

“No.”

“Ah.”

This was probably some kind of repression, and exactly the opposite of the psychotherapeutic method that Michel would probably have recommended. But they were not steam engines. And some things were no doubt better forgotten. He would have to work on once again forgetting John’s death, for instance; also on remembering better those parts of his life when he had been most social, as during the years of work for Biotique in Burroughs. So that across the cockpit from him sat Counter-Ann, or that third woman she had mentioned — while he was, at least in part, Stephen Lindholm. Strangers, despite that startling encounter at Underhill. Or because of it. Hello; nice to meet you.

Once they got out from among the fjords and islands at the bottom of Chryse Gulf, Sax turned the tiller and the boat swooped northeast, rushing across the wind and the whitecaps. Then the wind was behind them, and with a • following wind the mast sail bloomed into its own splayed-wing version of a spinnaker, and the hulls surfed on the mushy crests of the waves before losing to their superior speed. The eastern shore of the Chryse Gulf appeared before them; it was less spectacular than the western shore, but in many ways prettier. Buildings, towers, bridges: it was a well-populated coast, as were most of them these days. Coming off Olympus all the towns must be a bit of a shock.

After they passed the broad mouth of the Ares Fjord, Soo-chow Point emerged over the horizon, and then beyond it the Oxia Islands, one by one. Before the water’s arrival these had been the Oxia Colles, an array of round hills that stood at just the height to become an archipelago. Sax sailed into the narrow waterways between these islands, each a low round brown hump, standing forty or fifty meters out of the sea. By far the larger percentage of them were uninhabited, except perhaps by goats, but on the largest ones, especially kidney-shaped ones with bays, the stones covering the hills had been gathered up into walls, which split the slopes into fields and pastures; these islands were irrigated, green with orchards laden with fruit, or pastures dotted with white sheep or miniature cows. The ship’s maritime chart named these islands — Kipini, Wahoo, Wabash, Nau-kan, Libertad — and reading the map Ann snorted. “These are the names of the craters out in the middle of the gulf, underwater.”

“Ah.”

Still, they were pretty islands. The fishing villages on the bays were whitewashed, with blue shutters and doors: the Aegean model again. Indeed, on one high point bluff there stood a little Doric temple, square and proud. The boats down below in the bays were small sloops, or simply row-boats and dories. As they sailed past Sax pointed out a hilltop windmill here, a pasture of llamas there. “It seems a nice life.”

They talked about the natives then, easily and without hidden tension. About Zo; about the ferals and their strange hunter-gatherer city-shopper lifestyle; about the ag nomads, moving from crop to crop like migrant laborers who owned the farms; about the cross-fertilization of all these styles; about the new Terran settlements elbowing into the landscape; about the increasing number of harbor towns. Off in the middle of the bay, they spotted one of the new big townships, a floating island of a seacraft, with a population in the thousands; it was too big to enter the Oxia archipelago, and looked to be headed across the gulf to Ni-lokeras, or down to the southern fjords. As the land all over Mars was becoming more crowded, and the possibility of settling on it more and more restricted by the courts, more and more people were moving onto the North Sea, making townships like these their permanent home.

“Let’s go visit it,” Ann said. “Can we?”

“I don’t see why not,” Sax said, surprised at the request. “We can certainly catch it.”

He brought the catamaran about and tacked south and west toward the township, pushing the cat as much as he could, to impress the seafarers. In less than an hour they had reached its broad side, a rounded scarp about two kilometers long and fifty meters tall. A dock just above the waterline had a section against the township that would rise, as an open elevator, and when they had stepped across from the cat to the dock and tied their boat on, they got into this railed-off section and were lifted up to the deck of the township.

The deck was almost as broad as it was long, its central area a farm with many small trees scattered on it, so it was hard to see the other side. But it was clear from what they could see that the circumference of the deck was a kind of rectangular street or arcade, with buildings on both sides that were two to four stories high, the outer buildings topped by masts and windmills, the inner ones opening into broad breaks where parks and plazas led inward to the crops and groves of the farm, and a big freshwater pond. A floating town, somewhat like a walled city in Renaissance Tuscany in appearance, except that everything was extraordinarily neat and orderly, shipshape as one might say. A small group of the ship’s citizens greeted them on the plaza overlooking the dock, and when they found out who their visitors were they were thrilled — they insisted the travelers stay for a meal, and a few of them guided them on a walk around the perimeter of the ship, “or for as far as you care to go, it’s a good fair walk.”

This was a small township, they were told. Population, five thousand. Since its launch it had been almost entirely self-sufficient. “We grow most of our food, and fish for the rest. There are arguments now with other townships about overfishing certain species. We’re doing perennial polycul-ture, growing new strains of corn, sunflower, soybean, sand plum and so on, all intermixed and harvested by robot, because harvesting is backbreaking work. We’ve finally got the technology to go home to gathering, that’s what it comes down to. There are a lot of onboard cottage industries. We’ve got wineries, see the vineyards out there, and there are vintners and brandy distillers. That we do by hand. Also special-function semiconductors, and a famous bike shop.”

“Most of the time we sail around the North Sea. There are some really violent storms sometimes, but we’re so big that we ride them out pretty easily. Most of us have lived here for all ten years the ship has existed. It’s a great life. The ship is all you need. Although it’s great fun to make landfall from time to time. We come down to Nilokeras every Ls zero for the spring festival. We sell what we’ve made and resupply, and party all night long. Then back out to sea.”
