Table of Contents is a collection of eight pieces that range from Alaska to New Jersey, describing, for example, the arrival of telephones in a small village near the Arctic Circle and the arrival of wild bears in considerable numbers in New Jersey, swarming in from the Poconos in search of a better life (Riding the Boom Extension, A Textbook Place for Bears).

In North of the C.P. Line the author introduces his friend John McPhee, a bush-pilot fish-and-game warden in northern Maine, who is also a writer. The two men met after the flying warden wrote to The New Yorker complaining that someone was using his name. Maine also is the milieu of Heirs of General Practice, McPhee’s highly acclaimed report–virtually a book in itself–on the new medical specialty called family practice. Much of it takes place in the examining rooms of a dozen young physicans in various rural communities, where they are seen in the context of their work with a great many patients of all ages.

Two relatively short pieces revisit the subjects of earlier McPhee books. Ice Pond demonstrates anew the innovative genius of the physicist Theodore B. Taylor, who developed a way of making and using with impressive results in the conservation of the electrical energy. Open Man describes a summer day in New Jersey in the company of Senator Bill Bradley.

In Minihydro, various small-scale entrepreneurs in New York State set up turbines at nineteenth-century mill sites and sell electricity to power companies. A nice little country waterfall can earn as much as two hundred dollars a year for someone with such a turbine. And, Under the Snow, McPhee Goes back into black bear’s dens in Pensylvania in winter, where he becomes intoxicated with affection for some five-pound cubs. They remind him of his daughters.
