6 78 The Smithsonian Institution 



In 1891 Secretary Langley deposited in the United States 

 Signal Office all the voluminous monthly records of the Insti- 

 tution and all the manuscripts and printed observations re- 

 lating to meteorology, subject to recall, but with the under- 

 standing that the entire official record of research and pro- 

 gress in this connection should be preserved intact by that 

 office, now the Weather Bureau, which has these investiga- 

 tions in charge. 1
