This work deals with a very interesting and important subject, 

 which appeals no less to the layman than to the scientific student. 

 The habits of sea-fish have only recently begun to be investi- 

 gated seriously, but their importance in connection with our great 

 fishing industries can hardly be overestimated. A great deal of 

 information relating to the migrations of fish has already been 

 accumulated, but it is scattered in books and periodicals fre- 

 quently difficult to obtain. The author has aimed at giving a 

 systematic account of the knowledge acquired, developing at the 

 same time a theory of migrations based upon the various stages in 

 the growth of fish in connection with currents. The book con- 

 tains descriptions of the spawning habits, the eggs and the young, 

 the passive drift to the feeding grounds, and the distribution of 

 the species due to migrations. Practically all families of fish 

 have been considered, but the important food fishes of the Northern 

 Hemisphere have received specially detailed treatment.
