" A big fly came down also and settled on a leaf close to her face; he had two round brown knobs on his head and at that range looked enormous, a prehistoric animal that had roamed the jungles of a forgotten world. First he stood on four front legs and rubbed the two back ones with sinuous ease up and down his wings, then he stood on the four back and rubbed the two front ones like an obsequious shopkeeper. "
