REPORT ON COURSES IN MINING GEOLOGY. 



By Assistant Professor H. L. Smyth. 



The courses in Mining Geology and allied subjects given by Mr. 

 Smyth were, by arrangement with the Department of Chemistry, 

 held in the Mineralogical Lecture Room of the University Museum. 

 The three courses began early in December, 1894, and ended in 

 the April recess, 1895 ; the open season before and after these 

 dates being reserved by Mr. Smyth for his own field-work and 

 other studies. During the April recess, a voluntary excursion 

 was made for the benefit of the students in the course on Mining 

 Geology to Pennsylvania and New Jersey, in the course of which 

 the nickel mine at Lancaster Gap, the iron mines at Cornwall, 

 several blast furnaces at Lebanon, the Bethlehem Iron Works at 

 South Bethlehem, the zinc deposits at Franklin, and the experi- 

 mental magnetic concentrating plant at Ogden were visited, the 

 latter by the permission of Mr. Edison. 



During the year the scientific library of Professor Raphael 

 Pumpelly was made accessible to the students in these courses, as 

 well as to those in the courses in Mineralogy, the Department of 

 Mineralogy having provided the room in which the library is 

 temporarily installed in the University Museum. The collection 

 includes upwards of three thousand bound volumes, besides nu- 

 merous pamphlets and maps ; it is especially strong in economic 

 geology, metallurgy, and mineralogy. 



Numerous additions have been made to the collections of mine 

 maps and of photographs illustrating the structural relations of 

 ore bodies. A number of typical specimens of ores were collected. 

 About one hundred thin sections were added to the series available 

 for study in the course on Pre-Cambrian Geology. 



The most pressing need in these courses is room for the proper 

 storage and arrangement of geological specimens, so that they can 

 be conveniently examined by students. During the past year two 

 rooms in the basement of the University Museum were used for 

 these purposes ; but in the coming year the rooms will be needed 

 by the Department of Mineralogy and Petrography. A number of 

 nstruments are needed in 'the course on geological surveying.
