PREFACE 



of Antarctica. Some readers may feel that other re- 

 gions have been somewhat neglected, but I think that 

 if the whole body of Antarctic literature be examined 

 it will be found to deal very dominantly with this 

 sector, i.e., that behind the coasts explored by Ross, 

 Scott, Shackleton, Mawson, Byrd, and others. Almost 

 all branches of science have been studied as regards 

 their Antarctic aspects more fully in this sector than 

 in any other. Moreover, it is the region with which 

 I have personal acquaintance. 



If this book gives the reader some conception of the 

 last great unknown area of the earth it will have accom- 

 plished its purpose.
