ANNUAL REPORT OF THE 



REPORT OF THE DEPARTMENT OF GEOLOGY AND 



GEOGRAPHY. 



By Reginald A. Daly. 



This year the permanent staff of the Department remained the 

 same as in 1913-1914. The assistants appointed for the year were : 

 Dr. W. P. Haynes and Messrs. Francis Chamberlain, F. L. Cole, 

 Sidney Powers, H. M. Sampson, E. W. Shuler, Edward Wiggles- 

 worth, and H. N. Witt. The Department was fortunate enough 

 to secure the services of Dr. Ralph Arnold, who in April gave a 

 course of ten lectures on the Geology of petroleum. He came at 

 the joint invitation of this Department and the Department of 

 Geology at the Massachusetts Institute of Technology, half of 

 the course being given at each institution. The lectures were 

 most stimulating and the geologists of Boston owe much to Dr. 

 Arnold for his generosity in interrupting his busy professional life 

 to give his masterly summary of a subject so important in eco- 

 nomics and technology. The success of this informal course 

 illustrates the need of a permanent professorship in the geology 

 of the non-metals. 



The number of students reached by the Department shows 

 another gratifying increase. A comparative table gives its 

 amount; it refers, however, only to courses taken during the winter 



sessions.
