An immediate success when if was first published in 1653, Walton's classic celebrtion of the joys of fishing continues to captivate anglers and nature lovers with its timeless advice and instruction.  Originally cast in the form of a dialogue between an experienced angler named Piscator and his pupil Viator, the book details methods for catching, eating, and savoring all varieties of fish, from the common chub to the lordly salmon. More than an engaging guide to the subtle intricacies of the sport, Walton's reflective treatise is a graceful portrait of rural England that extols the pleasures of country life.   'The Compleat Angler  is not about how to fish but about how to  be ,' said novelist Thomas McGuane. '[Walton] spoke of an amiable mortality and rightness on the earth that has been envied by his readers for three hundred years.'
