Created by Act of Congress in 1849, the Department of the Interior 

 is responsible for a wide variety of programs concerned with the manage- 

 ment, conservation, and wise development of America's natural resources . 

 For this reason it often is described as the "Department of Natural

 are managed to produce optimum yields, and that all resources contribute 

 their full measure to the progress, prosperity, and security of America, 

 now and in the future .
