vi PREFACE 



great detail in the consideration of the multitude of 

 marine products. This book, however, will give the 

 reader a general conception of the fishery and 

 marine products industries. If further details or 

 statistical data are desired, they may be found in 

 the author's "Marine Products of Commerce." ^ 



Since it is not possible to discuss the fishery 

 methods employed in all parts of the world in the 

 space of a few hundred pages, American methods 

 and products have been described in most instances. 

 In the case of products which are not produced in 

 quantity in this country, such as pearls and coral, 

 the more important foreign methods have been given 

 consideration. 



In order to make the book interesting to the 

 general reader, the descriptions of technical proc- 

 esses have been made simple, non-technical, and brief. 

 Scientific names and technical terms have been 

 omitted in nearly all cases, and care has been used 

 to define all unusual words and phrases. While the 

 author has attempted to make the book a readable 

 one and has for this reason included some unusual 

 and curious tales of the fisheries, those which are 

 not absolutely authentic are clearly indicated. 



The author owes much to those who aided in the 

 preparation of this book. Special thanks are due 

 Dr. Samuel F. Hildebrand, of the U. S. Bureau of 

 Fisheries, for the preparation of the sections 

 "Fishes" and "Marine Turtles and Terrapins." Mr. 

 M. P. Greenwood Adams, of Melbourne, Australia,
