are building new lands for future aeons. 

 The sea is also guardian of the past — in 

 its depths live creatures who found earth 

 life too difficult and retreated to the pro- 

 tecting ocean while their less flexible 

 contemporaries merely subsided into 

 extinction. 



IN SCIENCE OF THE SEVEN SEAS, a 

 seagoing scientist explains how Nature's 

 laws govern the unquiet waves, the shape 

 and movement of clouds drifting through 

 the sky in seeming aimlessness, the storms 

 of wind and rain and snow that peril 

 ships at sea. 



In his lively text, punctuated with 

 sketches and photographs, the author 

 turns scientific discoveries in ocean- 

 ography, geophysics, hydrodynamics, 

 meteorology and astronomy into easily 

 understood descriptions of waves, ocean 

 currents, submarine topography, icebergs, 

 marine animals and plants, cyclones, 

 clouds, mirages, winds, stars and planets. 

 Ocean birds, fishes, aquatic animals 

 and plants are featured in a photographic 

 section that will delight those interested 

 in ocean life. 



Natural science enthusiasts, seamen, 

 Scouts, students, pleasure voyageis — all 

 who sail the sea or dream of sailing the 

 sea — will find SCIENCE OF THE SEVEN 

 SEAS a fascinating, nontechnical intro- 

 duction to natural phenomena observed 

 at sea.
