Report on the Canal Zone Biological Area 



Sib : It gives me pleasure to present herewith the annual report on 

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

 1957. 



SCIENTISTS, STUDENTS, AND OBSERVERS 



Anyone with serious interest in tropical wildlife may use the field, 

 laboratory, and living facilities on Barro Colorado Island. These 

 people may stay on the island overnight, or for periods of weeks or 

 months. Some who visit the island carry out technical scientific re- 

 search, while others come to familiarize themselves with the wildlife 

 and its environment. Most of them are residents of the United 

 States, but some are from the Canal Zone or Europe. Following is a 

 list of the 61 scientists, students, and observers who, during the past 

 year, used the island living facilities and stayed at least one night.
