This is Marshall's account of exploring the area which is now Gates of the Arctic National Park. Marshall was the first to systematically explore and describe it, in the 1930s. Introductions by his brother George update the information to 1970. There are wonderful, hilarious anecdotes. I read this to help plan my first trip there (summer 2000); can't imagine going without it.

Pond Life is like a general biology introduction to life found in ponds. All types of life are covered, albeit in very brief introductions. Plants and animals (microscopic to mammals to birds) each receive tertiary coverage. The book does not get into specifics on how wetlands function relation to other ecosystems, and such coverage would have been useful, but the overall emphasis is still relevant.

The book is likely not intended to be read from cover to cover, as it is a field guide. Field guides are really meant to be brought along in a pocket for easy reference when making field identifications. In this respect, I am a big fan of other field guides in the series.

This volume and its companions should be readily available at nature centers, but the price is low enough for people to purchase it for their own libraries. What it lacks in detail it makes up for in compactness and readability.

Golden Guides are often described as books for children just discovering the natural world. While the series is eminently usable by young naturalists, Golden Guides are solid introductory field guides. One of the strengths of "Pond Life" is its comprehensive scope covering everything from protozoa to plants to mammals. Indeed, it provides more good basic information on identifying types of water plants than any other source I know complete with measurements and color illustrations. The same applies to its coverage of invertebrates as well, though the minor objection of the previous reviewer concerning its scanty treatment of protozoa is a valid one. I would add to the strength of "Pond Life" its portability, which packs a plethora of information into a small package. Another weakness (of the Golden Guides in general) is its datedness to the 1950's and 60's. This does not affect its basic science in most cases, though it is strange (albeit nostalgic for some) to see the equipment suggested for pond watching.

E.O. Wilson, in his beautiful and brilliant autobiography, has stated that if he could live his life again, he would do so as a microbiologist who would dedicate himself to the study of a single tree and the area immediately surrounding it. He would investigate the organisms and the ecology of that small space, finding enough there to occupy his interest for a lifetime of exploration and research.

Given the same choice, I would choose a pond as my area of study, and this book would be one of the first field guides I would use. It is a basic introduction to the study of small bodies of fresh water: their defining characteristics, the forms they take through the seasons, the cycle of their lives, and the distinct forms they take throughout the United States. It also touches on the physical and chemical characteristics of water, and the importance these have for the organisms that live in or near the pond. The book introduces the concept of food webs and the multiple habitats of lakes and ponds, and also lists and describes some of the basic collecting tools of the limnologist (one who studies bodies of fresh water). The majority of the book is dedicated to the plants and animals which are frequently found near ponds. As one would expect, the emphasis is on how these organisms relate to the others in this environment, whether they are full or part time denizens, and in what types of ponds they can be found. More than merely a book about creatures found in ponds, it presents information about the pond itself and how its many inhabitants and visitors relate to one another there.

The book has two small weaknesses. The first is a slight bias towards organisms found only east of the Mississippi. There is enough information about ponds in general, however, to make this guide useful for any budding limnologist. The second flaw is that the sections on the protozoa and other microscopic organisms are far too short, but as a protozoologist I am perhaps biased. Still, I think that even a few more pages would have added to the value of this section by demonstrating the amazing complexity of these phyla.

As it is, however, the book functions admirably as an introduction to the study of ponds: it will lead beginners into the natural world, and to help them identify what they find there. It is suited for older children and adolescents, and will still be of some use at the college level, if only because it includes a list of more technical reference books. I recommend it for anyone who wants to "take the plunge" into the study of this fascinating environment!
