PREFACE 



book: "No other sources of information can ever make 

 up for that uUimate master knowledge revealed by men's 

 eyes, or for that less tangible but even profounder 

 knowledge attained emotionally by the soul of man 

 rather than his mind." 



If this book increases a sense of wonderment in its 

 readers' minds regarding the sea, in the sense indicated 

 by these quotations, its purpose will be fulfilled. 



I must express my sincere gratitude to Frank W. Lane, 

 author of that monumental and fascinating book King- 

 dom of the Octopus, for checking my chapter on the 

 cephalopods. My thanks are also due to Mr. H. A. 

 Humphrey of the Oldbourne Press for creative criticism ; 

 to correspondents in several countries (particularly 

 Fletcher King of Florida and others in the U.S.A.) for 

 news clippings ; and especially to my wife for her invalu- 

 able help in reading the MS. of this book.
