 collection to the custody of the Congressional, and gave to 

 it yearly accessions. The magnitude of this renunciation is

 archives to the new organization. 



The growth of the National Museum, and its management,

 them were offered to our government, on the understand-

 Smithsonian was the custodian of important collections 

 made by the explorers of this country in our Western Ter-

 together by the Wilkes expedition. Baird saw the oppor- 

 tunity to combine these elements and institute a national
