The United States National Herbarium, which was founded by the 

 Smithsonian Institution, was transferred in the year 1868 to the 

 Department of Agriculture and continued to be maintained by that 

 department until July 1, 1896, when it was returned to the official 

 custody of the Smithsonian Institution. The Department of Agri- 

 culture, however, continued to publish the series of botanical reports 

 entitled "Contributions from the United States National Herba- 

 rium," which it had begun in the year 1890, until, on July 1, 1902, 

 the National Museum, in pursuance of an act of Congress, assumed 

 responsibility for the publication. The first seven volumes of the 

 series were issued by the Department of Agriculture.
