Jim Corbett was every inch a hero, something like a ''sahib'' Davy Crockett: expert in the ways of the jungle, fearless in the pursuit of man-eating big cats, and above all a crack shot. Brought up on a hill-station in north-west India, he killed his first leopard before he was nine and went on to achieve a legendary reputation as a hunter. Corbett was also an author of great renown. His books on the man-eating tigers he once tracked are not only established classics, but have by themselves created almost a separate literary genre. Man Eaters of Kumaon is the best known of Corbett's books, one which offers ten fascinating and spine-tingling tales of pursuing and shooting tigers in the Indian Himalayas during the early years of this century. The stories also offer first-hand information about the exotic flora, fauna, and village life in this obscure and treacherous region of India, making it as interesting a travelogue as it is a compelling look at a bygone era of big-game hunting.
