This early twentieth-century guide to the geography and geology, fauna and flora of Cambridgeshire was written during a period when natural history played a particularly prominent role in British cultural life. The heart of the book is a comprehensive survey of the diversity of animal life in the region, focussing particularly on the insect orders. It also includes chapters on vertebrate palaeontology and archaeology. Two maps show locations of discovery of ancient skulls, as well as important ancient roads that cross the county. There are additional botanical and geological maps. The book provides a valuable baseline for present-day studies of biodiversity or the effects of climate change, and will also appeal to local enthusiasts with an interest in environmental history.
