B.— SPECIAL TOPICS OF THE YEAR. 



CLASSIFIED SERVICE OF THE MUSEUM. 



A schedule representing the present actual needs of the service was, 

 in response to a Senate resolution, submitted by the Secretary of the 

 Smithsonian Institution. By this it was shown that the sum of $200,000 

 at least was required to pay the salaries of the necessary scientific 

 assistants, the clerical force, mechanics, and laborers, for the construc- 

 tion of suitable cases, and for the employes connected with the heating, 

 lighting, electrical, and telephonic service.
