exhibition buildings are under construction at the National Zoological 

 Park and are expected to be completed by January 1937. 



Toward the end of the year a weekly radio program on the activi- 

 ties of the Smithsonian Institution was put on the air by the Office 

 of Education, Department of the Interior, in cooperation with the 

 National Broadcasting Company. The program consists of weekly 

 half-hour dramatizations of science and art over a Nation-wide 

 hook-up. The mail response from listeners has been enthusiastic. 

 The sales of the Smithsonian Scientific Series, a set of 12 popular 

 science volumes written by members of the Smithsonian staff and 

 collaborators, have continued to increase until at the present time a 

 total of nearly $150,000 has been received by the Institution in royal- 

 ties for the furtherance of its researches. In the will of the late 

 Dr. William L. Abbott, long a collaborator and friend of the Institu- 

 tion, a one-fifth share of his residuary estate was left to the Smith- 

 sonian to promote zoological researches. The executors state that 

 this share will be in the neighborhood of $100,000. 



The Institution has continued its w^ork on the problem of Folsom 

 man through the investigations of Dr. F. H. H. Roberts, Jr., near 

 Fort Collins, Colo. Additional information has been obtained on' 

 this earliest known Amxcrican aboriginal culture, as well as further 

 evidence of the contemporaneity of Folsom man with extinct species 

 of bison. In Alaska Dr. Ales Hrdlicka and Henry B. Collins, work- 

 ing independently, have continued to seek for direct evidence of the 

 ancient migration of the American Indians from Asia, with valuable 

 results. 



Outstanding among the year's publications were : Solar Radiation 

 and Weather Studies and The Dependence of Terrestrial Tempera- 

 tures on the Variations of the Sun's Radiation, by C. G. Abbot, 

 summarizing his investigations on the relationship of our weather 

 to variation in the sun's radiation; An Introduction to Nebraska 

 Archeology, by William Duncan Strong, a monographic work on 

 the archeology of that important region; and MoUuscan Intermedi- 

 ate Hosts of the Asiatic Blood Fluke, Schistosoma japonicum, and 

 Species Confused with Them, by Paul Bartsch, a definitive classifi- 

 cation of the intermediate hosts of this human parasite, which( 

 affects millions of Orientals, particularly the Chinese. Suggestions 

 for its control are included.
