This book is an effort...to experience and appreciate the taiga world through the sense of the animals themselves."" Mr. Pruitt introduces the reader to the world of the red squirrel, the vole, the hare (whose horizon is limited to ten acres), and that of the wolf, the caribou, the moose. His story, particularly of the effect of poison on the population of the Great North woods, underscores his statement that the ""intricate interweaving of relationships that results in the tundra ecosystem is clearly a fragile thing."" The land also is vulnerable--to erosion and fire--when homesteaders destroy ground cover, but his epilogue offers hope for the preservation of the Northland. Mr. Pruitt sounds a woodland note that will appeal to nature lovers.
