University College of Addis Ababa 



The University College of Addis Ababa is planning 

 to open a field station located at Lake Awassa in October 

 1963. The site for the station was chosen because of its 

 accessibility and its central location among the lakes of 

 the Ethiopian Rift Valley. Inquiries may be addressed 

 to Prof. J. T. Macfarlane, Dean, Faculty of Science, 

 University College of Addis Ababa, P. O. Box 399,
