THE FIRST FIVE FATHOMS

As the first five fathoms—approximately thirty feet—are the most vivid and the most accessible to man, this excellent text on diving restricts itself to that area of underwater life. The authors describe man's capacity in diving, both with and without mechanical aids, suggests various sports and activities available to the diver—hunting, photographing, salvaging— and describe the various forms of life, dangerous and friendly that reside beneath the sea. With skin diving reaching ever greater dimensions of popularity, this illustrated book is both informative and inviting and should appeal to any reader who in any form enjoys water sports.
