It figured that as the animals had been dropped on ten thousand sites, they would get opposition in some places; at least so it seemed in advance, although no one was sure of anything. In any case they worked as if they had only a few days of freedom to do so, and used helicopters like hoppers to move around, setting loose robotic sun-powered tractors, which hauled seeders that looked like the farming machinery one saw in photos from long before. Some of these planted trees two meters tall at a rate of sixty per hour until their supplies were exhausted. Thus the reanimation included a botanical element, and the tractors proved hard to stop. And few people tried.

Still there were incidents, and in Yellowknife as they ate they checked the stories coming in from around the world. It was everything from hosannas to artillery fire: cheered or denounced, and everything in between, from every possible source, including the U.N. Security Council, gathered in emergency session and yet at a loss. Orangutans back all over Southeast Asia, river dolphins in all their old river mouths, tigers in India and Siberia and Java, grizzly bears back in their old range in North America… was this not the alien invasion feared for so many centuries, come at last? It was unpermitted; it was disruptive; the animals included carnivores that could kill people; it had to be bad. Certainly it was confusing. And power, confused, was always dangerous.

But they also saw the Terran news noting that the animals were always landing in their original native habitats, shifted if necessary to adjust to climatic change since their disappearance. Also, that although they were not genetically modified organisms, an intense breeding effort in the terraria had created much more genetically diverse animals than the remnant Earthly populations. This was part of Wahram’s publicity packet information, so he was particularly pleased to see the media pick that up. Also the reports were noting that animals had for the most part come down in wilderness preserves, and in areas of hills, deserts, pasturage, and other least-human-impacted spaces—never in cities, and only once or twice in villages. A Colombian village that suffered an aerial invasion of sloths and jaguars had already renamed itself Macondo, and clearly would live to tell the tale.

For a while Swan slept on a couch in their impromptu conference center. Wahram found he was not comfortable letting her out of his sight. She was still acting very affectionately toward him, cast into some kind of ecstasy by her night spent with the wolf. Sleeping with her head on his leg. The poor thing looked emaciated still, somewhat as in the tunnel.

“I want to go back out,” she said now when she woke up. “Come with me. I want to follow the caribou again, and they need beaters. Maybe I’ll see my wolf too.”

“All right.”

He saw to the arrangements, and the next morning they joined the rest going north that day, and heloed out in a frost-steamed sunrise. “Look,” Swan said as the sun cracked the distant horizon, leaning over him to stare right into it.

“You can burn your eyes here too,” he said. “You can burn your eyes out even on Saturn.”

“I know, I know. I look without looking.”

The new light cracked in shards on the numberless patches of water spread on the land. Near the Thelon River they landed and got out, the helo buzzed away, and suddenly they were on the vast windy tundra, walking on variously crunchy or squishy ground, in some ways like the icy ground of Titan. Wahram upped the support of his body bra and tried to accustom himself to the give of the soggy land. For a while the act of walking over the broken ground of the semi-frozen caribou path felt like working in a waldo, and because of the body bra, in a way it was.

He straightened up and looked around. Sunlight mirrorflaked off water into his brain, and he adjusted the polarization in his glasses. Swan kept pulling down her glasses to look around with her naked eyes: sometimes she reeled, tears frozen on her cracked red cheeks, but she laughed or moaned orgasmically. Wahram only tried it once.

“You’re going to go blind,” he told her.

“They used to do it all the time! They used to live without any glasses!”

“I believe the Inuit protected their eyes,” he groused. “Strips of leather or some such thing. Anyway, it was something to withstand. They were stunted by life up here, held back from full humanity by their own harsh planet.”

She hooted at this and threw a snowball at him. “How you lie! We are bubbles of Earth! Bubbles of Earth!”

“Yes, yes,” he said. “ Lark Rise to Candleford. We were taught it too. ‘When alone in the fields, with no one to see them, they would hop, skip, and jump, touching the ground as lightly as possible and crying, “We are bubbles of Earth! Bubbles of Earth! Bubbles of Earth!” ’ ”

“Exactly! You were brought up Unitarian?”

“Aren’t we all? But no, I read it in Crowley. And I can’t hop, skip, or jump in this g. I would trip and fall.”

“Oh come on, get tough.” She regarded him. “You must weigh a lot here. But you’ve been here a long time, you should be used to it.”

“I haven’t been doing much walking, I confess. My work has been more sedentary.”

“Recreating Florida, sedentary? Then it’s good you’re out here.”

She was happy. He stumped along comfortably enough; he had been exaggerating the impact of the g, just to annoy her. Now the cold air and the sunlight were giving the day a kind of crystalline quality. “It is good,” he admitted.

So they walked the southern edge of the caribou’s route east, and Swan planted transponders and photographed tracks and took soil and fecal samples. In the evenings they gathered with other trackers at a big dining tent set up daily in a new position. In the short nights they lay on cots in the same tent and caught a few hours of sleep before eating and heading out again. After the third day of the beat they had to deal with the helicoptered arrival of the Royal Canadian Mounted Police, who arrested them and flew them to Ottawa.

“No way!” Swan cried as they watched the land unfurl below them. “We weren’t even in Canada!”

“Actually we were.”

The vast fields of wheat at midday looked very different than they had during their recent morning trip out. “Look at that!” Swan exclaimed at one point, gesturing down with disdain. “It looks like an algae bloom on a pond.”

In Ottawa, when they were released from custody, Swan took Wahram to the Mercury House to clean up and try to find out what was happening. News of the reanimation was still all over, and there were too many stories to tell, because everyone in the world was telling their story at once, in the usual manner but even more so; so it was hard for them to find out their own story—specifically, why they had been arrested. They had been released without charge, and no one in Ottawa seemed to know anything about why they had been pulled in.

On the newsfeeds clusters had already formed, one could watch images arranged alphabetically by animal or region or several other categories—worst landings, animal actions beautiful or comic, human cruelties against animals, animal aggression against humans, and so forth. They watched the screens in the dining hall as they ate, and afterward walked the narrow streets by the blackish river and canal system, dropping in on pubs here and there to have a drink and see more. Soon enough Swan was getting in drunken arguments with other patrons; she made no secret of her spacer origins, which would have been hard to do anyway, given the way she looked, and the graceful but stylized way she moved in her body bra. Wahram thought people looked up at her with a bit of fear in their gazes. “A round on the Mercury House, that’s where I’m from,” she would declare when people got pissy, which of course helped, but wasn’t a complete solution.
