"I think of the fox that Park Service Ranger Gene Parker told me about. The fox sprawled naked and pink-skinned in a mountain field, unable to rise, dying of mange. I think of the swimming bluegill I saw at the Lawsons', upstream in Tinker Creek on the other side of Tinker Mountain. One of its eyes was blinded by an overgrowth of white water mold, a white that spread halfway down its back in filmy lumps like soaked cotton batting. It had been injured, perhaps when a fisherman had hooked it and tossed it back, perhaps when a flood dashed it on rocks, and the fungus had spread from the injured site. I think of Loren Eiseley's description of a scientist he met in the field, who was gleefully bearing a bloody jar squirming with yard after yard of some unthinkable parasite he had just found in the belly of a rabbit. Suddenly the lives of the parasites—some sort of hellish hagiography—come to mind. I remember the bloodworms and flukes, whose parasitic life cycles require the living bodies of as many as four hosts. How many of the grasshoppers that hurtled around me in the Lucas meadow bore inside their guts the immense coiled larvae of horsehair worms?"
