THE EXTERMINATION OF WILD LIFE 25 



sands, and certain of these haunts, such as Marsh Island 

 and Klamath Lakes, have been set aside as bird refuges.

 of any animal cannot be prevented unless such an animal is 

 sufficiently protected to obviate the danger of its destruc- 

 tion at a greater rate than its natural increase.
