"Trees, now--Slothrop's intensely alert to trees, finally. When he comes in among trees he will spend time touching them, studying them, sitting very quietly near them and understanding that each tree is a creature, carrying on its individual life, aware of what's happening around it, not just some hunk of wood to be cut down. Slothrop's family actually made its money killing trees, amputating them from their roots, chopping them up, grinding them to pulp, bleaching that to paper and getting paid for this with more paper. "That's really insane." He shakes his head. "There's insanity in my family." He looks up. The trees are still. They know he's there. They probably also know what he's thinking. "I'm sorry," he tells them. "I can't do anything about those people, they're all out of my reach. What can I do?" A medium-size pine nearby nods its top and suggests, "Next time you come across a logging operation out here, find one of their tractors that isn't being guarded, and take its oil filter with you. That's what you can do.""
