This Smithsonian radio series has proved to be an excellent means 

 of disseniinatin*^ authentic scientific information, and Mr. C'lark 

 had already begun at the close of the fiscal year to arrange the 

 program for the coming year. It is intended to increase not only 

 the scope of the talks, but also the audience to be reached by 

 exchanging material with Westinghouse station WBZ, of New 

 England. 



Plans were under way also, near the close of the year, for a distinct 

 series of radio talks on the National Zoological Park, to be presented 

 by the superintendent of the park and others who have a special 

 Imowledge of certain groups of animals shown in the pai'k. It is 

 expected to begin this series in October, 1925.

The publications of the Institution constitute its principal means 

 of carrying out one of its main piu'poses, "'the diffusion of knowl- 

 edge among men." With the 11 distinct series now issued, a very 

 wide field of readers is reached, as in addition to the technical 

 papers, intended for use by scientists and students, a semipopular 

 account of progress in all branches of science is presented to the 

 general reader in the appendixes to the annual reports of the Institu- 

 lion. As explained in last year's report, these reports have since 

 the war been issued over two years late. Last year, however, funds 

 were provided to enable the Institution to bring them up to date
