auspices of the Teachers' School of Science a course of fifteen 

 lectures and laboratory exercises on the Geography of the United 

 States was given to a class of over one hundred teachers. During 

 the Spring recess Professor Johnson conducted a party of seventeen 

 students and teachers, representing eight New England and New 

 York educational institutions, on an excursion in the Catskill 

 Mountains. A two-days' excursion to Cape Cod was partici- 

 pated in by seven students. 



During the first half-year the work in Geology 12, conducted 

 by Mr. F. H. Lahee, consisted of the mapping and study of the 

 geology of an area, and, in the second half-year, of special field 

 problems. Mining 28, a half course in field geology and geological 

 surveying given to students in the Division of Mining and Metal- 

 lurgy, was completed by ten students. In the April Recess a 

 small party of graduates and undergraduates, under the direction 

 of Mr. Lahee, studied the structure and stratigraphy of selected 

 localities in the vicinity of Catskill, N. Y. Mr. Lahee devoted 

 most of the summer to the investigation of the petrology of the 

 Narragansett Basin.
