During the winter season the students in advanced classes 
attended regular evening meetings designed to serve the purpose 
accomplished by the Seminaria of the German Universities. 
During the summer of 1888, twenty-three students, twelve 
of whom had been previously trained in the classes of the Uni- 
versity, received systematic instruction in field-work. Fifteen 
of these persons were included in the Summer School of Ele- 
mentary Geology, which was taught in Cambridge, in Rhode 
Island, Southern Connecticut, and the Catskills, by the officers 
of the department. Hight of these students received instruc- 
tion in an Advanced Summer School of Geology, under the 
direction of N.S. Shaler. 
The Summer School of Geology was in charge of Professor 
Davis during its two weeks’ stay at Meriden, Conn., and 
Catskill, N. Y. 
During the year, the following papers of a scientific nature 
have been published by N.S. Shaler : — 
1. Caverns and Cavern Life. Scribner’s Magazine, Vol. II., No. 4, 
October, 1887, pp. 449-472.

The course in Physical Geography and Meteorology (N. H. 1) 
was given to fifty students. During the absence of Professor 
Davis in the second term, the lectures were given by Mr. T. W. 
Harris. Laboratory work, chiefly on weather charts and geo- 
graphic models, together with frequent oral and written exer- 
cises, occupied one of the three weekly appointments.
