The author, ""Germany's most successful and versatile animal lover,"" has done several notable books on animal lore prior to this one. Previously preoccupied with the fate of wildlife in Africa, Mr. Grzimek now turns his attention to the Northern Hemisphere, focussing primarily on Russia where he spent several months. His ""depressive"" findings show that Russia, like America, is doing too little, too late in its conservation efforts. Nevertheless, this is an impressive overview of a number of the species, still more or less intact, that are native to the northern regions: Lynx, Saiga antelope, marmots, bison, ibex, the polar bear, the leveret, storks, salmon, elk, even the white mouse is included. It's a folksy yet intelligent survey combining history, fact, story and legend. There are a number of good photographs by the author. And, as a secondary concern, the book gives glimpses of the Russian Way; for instance, in Moscow, the sale of dogs is running way behind that of pigeons, fish, cage birds and other small pets. In fact, dogs are even banned in certain sectors. But the Russians are animal lovers and so is the audience for this book.
