This book contains nothing but information,"" states the author. He might have added, vital information. It is a survival kit for facing disaster of every nature or cause, natural or man-made, from fire to flood to atomic or personal violence. How to get help, or give it (the SOS, artificial respiration), how to help oneself are covered concisely in chapters headed to the point: too lonely, too crowded; too dry, too wet; too bright, too dark; too cold, too hot; too low, too high; too fast; too empty. On the premise that ""survival belongs not to the strong but to the prepared."" Mr. Greenbank has provided authoritative advice on a wide range of situations.
