And what do they make in this factory? Why, the vermin of Palimpsest. There is a machine for stamping cockroaches with glistening green carapaces, their maker’s mark hidden cleverly under the left wing. There is a machine for shaping and pounding rats, soft gray fur stiff and shining when they are first released. There is another mold for squirrels, one for chipmunks and one for plain mice. There is a centrifuge for spiders, a lizard-pour, a delicate and ancient machine which turns out flies and mosquitoes by turn, so exquisite, so perfect that they seem to be made of nothing but copper wire, spun sugar, and light. There is a printing press for graffiti which spits out effervescent letters in scarlet, black, angry yellows, and the trademark green of Casimira. They fly from the high windows and flatten themselves against walls, trestles, train cars.
