THE SMITHSONIAN INSTITUTION. 



THE ESTABLISHMENT. 



The Smithsonian Institution was created by act of Congress in 

 1846, according to the terms of the will of James Smithson, of Eng- 

 land, who in 1826 bequeathed his property to the United States of 

 America "to found at Washington, under the name of the Smith- 

 sonian Institution, an establishment for the increase and diffusion of 

 knowledge among men." In receiving the property and accepting 

 the trust Congress determined that the F.ederal Government was 

 without authority to administer the trust directly, and therefore 

 constituted an " establishment " whose statutory members are " the 

 President, the Vice President, the Chief Justice, and the heads of 



the executive departments."
