 part of the operator is therefore a large part of the game. It 

 sometimes happens that individual chipmunks or other animals 

 are found which refuse to tolerate the camera, and then a new 

 subject must be hunted up. In my own experience, certain in- 

 dividuals have been found that were much easier to photo- 

 graph than others of the same species at the same time and 

 place. 



The success of the photographer in this field will depend on 

 three things: suitable equipment, patience, and some knowl- 

 edge of the habits of the individual animal to be photographed.
