and Fisheries and his aids at Washington, and to 

 the Fish Commissioners of New England States 

 and Canada, I am greatly indebted for placing at 

 my disposal valuable literary data and for facilita- 

 ting careful and minute study of fish in the various 

 hatcheries. 



From Dr. James A. Henshall, Superintendent 

 of the United States Fish Commission Station at 

 Bozeman, Montana, I have received much encour- 

 agement from the inception of the work ; and dur- 

 ing its preparation I have had the advantage of his 

 long experience and his deep knowledge of the 

 subjects treated. 



Mr. E. T. D. Chambers, of Quebec, kindly 

 consented to cover the field embracing the fishes 

 of Eastern Canada, and Mr. G. M. Fairchild, Jr., 

 of Cap Rouge, Quebec, has favored me with the 

 benefit of his experience. 



The author is under deep and continued obliga- 

 tion to many kind friends and fellow-anglers who 

 have aided him greatly in the production of the 

 work. To the following gentlemen, among 

 others, he wishes to express his earnest apprecia- 

 tion : Mr. Eugene McCarthy, of Syracuse ; Mr. 

 Archibald Mitchell, of Norwich, Connecticut ; 

 Mr. Charles Frederick Stansbury, of New York ;
