Piers Vitebsky is Head of Anthropology and Russian North- ern Studies at the Scott Polar Research Institute, an appealing Cambridge institution whose lecture halls are hung with polar bear skins and whose staff and students are summoned to tea and biscuits every morning by the ship’s bell of the Terra Nova. Part memoir, part social study, his book is a warm and lucid tribute to the Eveny, a 17,000-strong reindeer-herding people from the far north-east of Siberia. Vitebsky has been visiting them since 1988, and thus witnessed the tail-end of the old Soviet system for dealing with the Siberian minorities and its replacement, amidst the chaos of the Nineties, with free enterprise and an embryonic native-rights movement.
