Pleasantly and simply written by a Pennsylvania housewife who is also a student of natural history, this book, aimed at the amateur rather than the professional naturalist, deals with nature study in general and with birds, fossils and shells in particular. As a child on a farm near Sewickley, Pa., the author was fascinated by geological formations and fossils; encouraged by sympathetic parents she early started her own collection of fossils, minerals and plants; later she became interested in conchology, collecting shells in all parts of the world. Her collections, expanded, classified and labeled, now form a private natural history museum of her own. She also ""collects"" birds, not in her museum but in bird sanctuaries and on feeding tables. The book, in effect a ""how-to"" volume, tells the amateur collector and nature student what to collect and how to preserve and house his collections; and also how to attract, feed and watch birds. Although not a juvenile, the book -- despite occasional descent into sentimentality, is a natural for the growing army of hobbyists,- city, town and country dwellers, for youthful enthusiasts and the middle aged who are just discovering an interest in nature. Not a book for rental libraries, nor-perhaps- for the incurable city dweller, but a good plus sale item for school libraries and natural history shelves in the non-scientific areas.
