THE CHALLENGE OF THE SEA

At a moment where interplanetary travel is the focal point of man's pioneering vision, the author, twice Chairman of the British Interplanetary Society, turns downward. In a fascinating and compact text he explores the mysteries of the earth's great frontier, the sea. He emphasizes the vast riches it contains, goes into dramatic detail as to the difficulties in penetrating its boundaries, describes its topography, vegetation, and fish-life. Many interesting projections into future sea life are indicated here in this lucid and stimulating text which will be equally enjoyed in school and home libraries.
