NOTE 
This volume contains the administrative reports of the Chief of 
the Bureau to the Secretary of the Smithsonian Institution covering 
the five-year period from July 1, 1919, to June 30, 1924. 
During a long period these reports have fallen behind, through 
lack of sufficient funds to publish and for other reasons, and it has 
been decided to print the five reports in this volume in order to give 
subsequent administrative reports current publication. 
This will not change the numerical order of the annual reports.
