THE CONTRIBUTIONS OF ZOOLOGY 

 TO HUMAN WELFARE' 



To indicate the contributions of zoology 

 to human welfare as related to or dependent 

 upon the aquatic resources is the task which 

 has been assigned to me, but because of 

 time limitations the subject must neces- 

 sarilj^ be covered in a superficial way. The 

 consideration of this phase of the general 

 topic, whose application may for present 

 purposes be restricted to the United States, 

 is based on the assumption that the condi- 

 tion of aquatic resources affects our na- 

 tional prosperity, and that full and accu- 

 rate knowledge of those resources is a pre- 

 requisite to their proper utilization. 



The theme is fertile and inviting, and 

 there should exist no difficulty in establish- 

 ing a case for zoological research as a note- 

 worthy contributor to our welfare. My 

 task is lightened by the readiness with 

 which nearly every one will recall important 

 roles that zoology has played in the modern 

 history of the fishing industry. 



It is doing no violence to truth or justice 

 to claim that the beginnings of sane and 

 beneficent fishery administration in the 

 United States date from the time when a 

 man, already eminent in science, with many 

 years' experience in zoological work, was 

 chosen by the President of the United States 

 as the proper person "to prosecute investi- 

 gations on the subject of the diminution of 

 the valuable fishes with a view of ascertain- 

 ing whether any and what diminution in
