If you have the misfortune of finding yourself drifting on a raft at sea or desperately foraging for food in the deep woods, you'd be lucky if you remembered to bring your SAS Survival Guide: How to Survive in the Wild, in Any Climate, on Land or at Sea (HarperCollins, $19.95). John "Lofty" Wiseman of the British Special Air Service provides a compendium of esoteric information for the stranded: cook ants for at least six minutes, zigzag when fleeing a rhino, and don't urinate while swimming in the Amazon because a catfish might swim up your urethra. For the more conventionally adventurous, Wiseman provides basic information, with color illustrations, of poisonous and edible fruits and fungi and of dangerous snakes. He illustrates knots and covers first aid. And for the stay-at-home, he provides food for the imagination. What if I did get stranded? Could I survive?
