Early adventures among the people, birds and wildlife of remote South Hampton Island -- "a nineteen-thousand-square-mile heap of rock that sprawls almost across the mouth of Hudson Bay." Sutton's account of a year among the Aivilikmiut, the walrus-hunting Eskimos in the 1930s, is full of enthusiasm, warmth and vivid detail of people and place. Along the way we learn a great deal about High Arctic birds and their biology. Illustrations based on the author's photographs and line drawings.  (ARC04, $24.95)
