Now commenced the rapid advancement in photog-

 the arts and sciences took greater and greater interest 

 in photograph)', until, finally, when the apparatus had 

 reached that stage of perfection that permitted it, 

 nature workers took up the camera. 



Nowadays the equipment of a worker in any of the 

 branches of the natural sciences is incomplete unless 

 it includes a photographic outfit, and it should be so 

 with the sportsman. 



It is in the hopes of inducing many who have here-

 those who wish to photograph the wild denizens of our 

 woods, fields, and streams, that this book is written. 



It is distinctly a book for the beginner, and to the 

 expert in nature photography it will probably prove of 

 little or no use. The suggestions and advice which I
