Report on the Canal Zone Biological Area 



Sir: It gives me pleasure to present herewith the annual report 

 on the Canal Zone Biological Area for the fiscal year ended June 30, 

 1956. The principal portion of this report was prepared by James 

 Zetek, who retired from the position of resident manager of this 

 bureau on May 30, 1956. Mr. Zetek has been succeeded by Dr. Carl 

 B. Koford who assumed his duties as resident naturalist on June 30, 

 1956. 



SCIENTISTS AND THEIR STUDIES 



During the fiscal year 51 scientists, not including the Corrosion 

 Conference group, came to the laboratory. Some of these, such as 

 the research team from the University of Oslo, stayed for extended 

 periods. In addition, there were many scientists who wanted to "get 

 acquainted" with the island and had scheduled a one-day stopover 

 to inspect the laboratory and the forest area.
