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 enthusiasis, seamen, 
Scouts, students, pleasure voyagers — 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 sed.
