Or he could keep a diary. Set down his impressions. There must be lots of paper lying around, in unburned interior spaces that are still leak-free, and pens and pencils; he’s seen them on his scavenging forays but he’s never bothered taking any. He could emulate the captains of ships, in olden times—the ship going down in a storm, the captain in his cabin, doomed but intrepid, filling in the logbook. There were movies like that. Or castaways on desert islands, keeping their journals day by tedious day. Lists of supplies, notations on the weather, small actions performed—the sewing on of a button, the devouring of a clam.

He too is a castaway of sorts. He could make lists. It could give his life some structure.

But even a castaway assumes a future reader, someone who’ll come along later and find his bones and his ledger, and learn his fate. Snowman can make no such assumptions: he’ll have no future reader, because the Crakers can’t read. Any reader he can possibly imagine is in the past.

A caterpillar is letting itself down on a thread, twirling slowly like a rope artist, spiralling towards his chest. It’s a luscious, unreal green, like a gumdrop, and covered with tiny bright hairs. Watching it, he feels a sudden, inexplicable surge of tenderness and joy. Unique, he thinks. There will never be another caterpillar just like this one. There will never be another such moment of time, another such conjunction.

These things sneak up on him for no reason, these flashes of irrational happiness. It’s probably a vitamin deficiency.

The caterpillar pauses, feeling around in the air with its blunt head. Its huge opaque eyes look like the front end of a riot-gear helmet. Maybe it’s smelling him, picking up on his chemical aura. “We are not here to play, to dream, to drift,” he says to it. “We have hard work to do, and loads to lift.”
