5. A course in Historical Geology, designed to give the student the 
training necessary to recognizing the principal geological horizons by 
their characteristic fossils. No lectures were given in this course, the 
instruction being altogether by directed study on the materials contained 
in the cabinet appropriated to students’ use. This course was attended 
by two students. 
Two courses of meetings for the discussion of work done by 
the students in Geology and Paleontology were held during the 
winter months. 
During the summer months ten of the advanced students 
in Geology received instruction in field work. Two graduates 
trained in this department, who received their degrees at the last 
Commencement, have been appointed to places in the United 
States Geological Survey. 
During the time when not occupied in teaching, I have been 
engaged as Geologist on the work of the United States Geologi- 
cal Survey on the coast line of New England. ‘The results of 
this work will in part be found in the forthcoming Report of 
the Director of that Survey.
