16 PHOTOGRAPHY FOR NATURALISTS. 



This instance is, of course, an extreme one, but 

 an almost equal incongruity of surroundings can be 

 easily effected by a little want of thought and pre- 

 liminary preparation. One is often sorely tempted to 

 seize the opportunity of securing a good photograph of 

 an animal, if one has the chance, regardless of its sur- 

 roundings. Sometimes one is compelled to do so. 



The proper course to pursue subsequently is to 

 block the animal out and make a fresh negative with 

 a suitable background. The labour is quadrupled, but 

 in such cases this is unavoidable.
