What provides ""the springs of adventure""? This is what Wilfrid Noyce, of Everest fame, sets out to explore. He finds varying answers in the writings of adventurers -- and has compiled here a blending of his own many-faceted interests and experiences as touchstone for what others have said and done:- airmen, speleologists, frogmen and divers, explorers and of course mountain climbers- these provide his main channels of investigation. From their writings he has culled revealing passages. While this has not the personal adventure angle of autobiographical appeal, it does touch on a common urge of youth.
