PLB 0-688-15269-4 George offers alert naturalists a chance to go sleuthing around the world, and the results are invigorationg. Miss Lewis, a teacher, is off circumnavigating Earth; she corresponds with the students back home, telling of her travels and the creatures she encounters in Peru, Antarctica, Kenya, China, Japan, Australia, Alaska, and an island off the coast of California. She describes the wildlife, mentions particular sites she visits, often throws in an anthropological nugget or two, and then ends with a question that relates to some unusual trace that has been left by an animal—gouges taken out of cliff faces, a tree stripped bare, mysterious snowballs around a hot spring, a trail cut through the stony tundra. The animal is subsequently identified, although readers will not know until the end of the book, where the traces are explained, exactly what has transpired. George doesn’t try to cram every page with information, but is selective, choosing material that distills the unique character of a place. Excellent, highly detailed illustrations accompany the text.
