The Animal World, A Book of Natural History / Young Folks' Treasury (Volume V)

A young-reader’s survey of animal life worldwide that offers concise, accurate sketches of major groups—mammals, birds, fishes, reptiles, amphibians, insects, and marine invertebrates—organized into focused chapters with representative species and illustrations. Each chapter describes characteristic anatomy, behaviors, habitats, and typical life habits, often using vivid examples to explain relationships among groups. Supplementary sections encourage outdoor observation, seaside nature-study, and ethical regard for living creatures. The prose aims to stimulate curiosity and train attention rather than provide technical taxonomy.
