20 ANNUAL REPORT OF THE 



REPORT ON COURSES IN MINING GEOLOGY. 



By Assistant Professor H. L. Smyth. 



During the past year the course in Mining Geology (Geology 10) 

 was given in the Mineralogical Section of the University Museum, 

 continuing the arrangement of the preceding two years. It is ex- 

 pected that this course will eventually find permanent quarters 

 in the Cary Building. 



The lamented death of Professor Whitney in the summer of 

 1896 made necessary a rearrangement of the courses in Economic 

 Geology. Geology 18 became a half-course in the first half-year, 

 instead of a full course, and was devoted to the consideration of 

 the non-metalliferous minerals. Professor Shaler undertook the 

 greater part of the work of this course, Mr. Smyth dealing only 

 with sulphur and the salts. It is proposed to continue this arrange- 

 ment for the coming year. Professor Whitney's course in the 

 Metals and Metalliferous Ores is represented by the parallel course 

 Geology 10. 



The collections in Economic Geology have received important 

 accessions during the year from Butte, Cripple Creek, Mercur, 

 Leadville, etc. Mr. Henning Jennings of Johannisberg has con- 

 tributed an interesting and valuable collection of ores from the 

 Witwaters Rand district in South Africa. 



During the year much time was spent in preparing for publica- 

 tion the results of geological field work done in the Upper Penin- 

 sula of Michigan in 1891 and 1892. While the work itself was 

 a private enterprise, an arrangement has been made whereby the 

 results are to be published under the auspices of the Lake Superior 

 Division of the United States Geological Survey. One instal- 

 ment of the final paper is mentioned in the list of publications 

 which follows.
