    Although there were of course locks for smaller maintenance vehicles to exit the main body of the starship, all located on the inner rings, with the biggest docking ports at the stern and bow of the spine, it was still true that each such excursion outside the ship lost a very small but ultimately measurable amount of volatiles from the opened locks. As there was no source of resupply before arrival in the Tau Ceti equivalent of an Oort cloud, these losses were avoided by the voyagers, who did not leave the body of the ship from the ferry docks except in extraordinary circumstances. One small triple lock in Inner Ring B was regularly used for excursions by individuals in spacesuits, including the paleo culture in Labrador.
    Within the various parts of the ship there were 2,004,589 cameras and 6,500,000 microphones, located such that almost every internal space of the ship was recorded visually and aurally. The exterior was monitored visually. All recordings were kept permanently by the ship’s operating computer, and these recordings werearchived by the year, day, hour, and minute. Possibly one could call this array the ship’s eyes and ears, and the recordings its personal or life memory. A metaphor, obviously.

    Freya continued her wanderjahr travels, returning to Ring B, then again to Ring A. In every biome she visited, she spent a month or two, depending on her accommodations, and the needs of her hosts and friends. She “met everybody,” meaning she met about 63 percent of any given biome’s population, on average. That was enough to make her one of the best-known individuals in the ship.
    Fairly often Euan met up with her and they took off into the infrastructure of the ship, exploring in a more and more systematic fashion the twelve spokes, the twelve inner ring rooms, the four struts connecting the inner rings, and the two outer struts that connected Costa Rica and Bengal, and Patagonia and Siberia. They sometimes joined other people, many of whom were unaware of each other, who were making efforts to explore every nook and cranny of the ship. These people often called themselves ghosts, or phantoms, or trail phantoms. Devi too had been one of these people, though she had not met the same people Freya and Euan did. Ship calculated there were 23 people alive who had made this their project, and through the course of the voyage, there had been 256 of them, but fewer as the voyage went on. It had been thirty years since Devi had made her own explorations. Most phantoms did their exploring when they were young.
    Freya continued asking people questions, and as a result of this habit her knowledge of the population, although anecdotal, was very extensive. Nevertheless, she could not perform the quantitative calculations that were involved in any statistical analyses that might have given her investigations any social science rigor or validity. She still made no hypotheses.
    She was not unique, or even very unusual, in how well she knewthe ship and its crew; every generation of the ship’s population had included wanderers, who became acquainted with more people than most. These wanderers were not the same as the phantoms, and there were more of them; on average they were about 25 percent of the population alive at any given time, although the rules regulating wandering had changed as the generations passed, and there were fewer than there had been in the voyage’s first sixty-eight years. What the wanderers served to demonstrate is that a population of just over two thousand people is one that a single human could, with an effort, come to know pretty well; but it had to be their project, or it wouldn’t happen.
    In most of the biomes she was now expected in advance, on a schedule of sorts, and welcomed and enfolded into the life of whatever settlement she joined. People wanted her. Possibly it could be said that many seemed to feel protective of her. It was as if she were some kind of totemic
