PREFACE 



various government documents; Mr. Alexander 

 Walker, of Butte, Montana, for valued informa- 

 tion given me on the Montana rainbow- trout; 

 and many others, among them those anglers who 

 have written me of their pleasure and success in 

 the use of my nature lures. 



All but three of these chapters have been printed 

 in various sporting magazines during the last five 

 years, but so much has been added and changed 

 to include my latest studies as to make them en- 

 tirely new. The periodicals in which these arti- 

 cles have appeared are the following: American 

 Angler, Field and Stream, National Sportsman, 

 Forest and Stream, Rod and Gun in Canada, 

 Metropolitan, New York Herald, Outing, Outer s 

 Recreation.
