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 Palaeontology 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.
