PREFACE 



The Tenth Expedition of the Department of 

 Tropical Research of the New York Zoological 

 Society was made possible by generous contribu- 

 tions from members of the Society. Its work 

 was carried on in the Bay of Port-au-Prince, Haiti, 

 where we studied the coral reefs and the fishes. 



The final results will materialize in a series of 

 scientific papers, which, it is hoped, will add 

 something to our knowledge of the life of the sea. 

 These will hardly be read by the general public, 

 hence I have chosen a few high -lights of the 

 expedition and crystallized them into these thirteen 

 chapters. 



As far as the actual experiences are concerned, 

 any reader of this volume may duplicate them. 

 The diving helmet, hose and pump, with which all 

 the research was done, are as inexpensive as they 

 are simple in operation. 



1 have had so many inquiries as to the inception 

 and cost and operation of a scientific expedition, 

 that I have thought it worth while to add several 

 appendices, giving, in brief form, the gist of this 

 information.
