The school door crashed open and there was Coyote, teacher for the day. Coyote traveled all over the world, and spent very little time in Zygote. It was a big day when he taught them. He led them around the village finding odd things to do, but all the time he made one of them read aloud, from books impossible to understand, written by philosophers, who were dead people. Bakunin, Nietzsche, Mao, Bookchin— these people’s comprehensible thoughts lay like unexpected pebbles on a long beach of gibberish. The stories Coyote had them read from the Odyssey or the Bible were easier to understand, though unsettling, as the people in them killed each other a lot and Hiroko said it was wrong. Coyote laughed at Hiroko and he often howled for no obvious reason as they read these gruesome tales, and asked them hard questions about what they had heard, and argued with them as if they knew what they were talking about, which was disconcerting. “What would you do? Why would you do that ” All the while teaching them how the Rickover’s fuel recycler worked, or making them check the plunger hydraulics on the lake’s wave machine, until their hands went from blue to white, and their teeth chattered so much they couldn’t talk clearly. “You kids sure get cold easy,” he said. “All but Nirgal.”

Nirgal was good with cold. He knew intimately all its many stages, and he did not dislike the feel of it. People who disliked cold did not understand that one could adjust to it, that its bad effects could all be dealt with by a sufficient push from within. Nirgal was very familiar with heat as well. If you pushed heat out hard enough, then cold only became a sort of vivid shocking envelope in which you moved. And so cold’s ultimate effect was as a stimulant, making you want to run.

“Hey Nirgal, what’s the air temperature?”

“Two seventy-one.”

Coyote’s laugh was scary, an animal cackle that included all the noises anything could make. Different every time too. “Here, let’s stop the wave machine and see what the lake looks like flat.”
