Dining 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 1890, forty-two students received in- 

 struction in the field. This instruction was given in three 

 graded schools, one of which, the elementary school, was taught 

 in Cambridge, and the other two in New York, Connecticut, 

 Massachusetts, New Hampshire, and Maine. Instruction in 

 these courses was given by N. S. Shaler, W. M. Davis, J. E. 

 Wolff, and T. W. Harris, with the assistance of Prof. H. S. Wil- 

 liams of Cornell University and Dr. W. B. Clarke of Johns 

 Hopkins, who collaborated , with the other instructors in the 

 work done in New York and Massachusetts. 



During the year, the following books and papers of a scientific 

 nature have been published by N. S. Shaler: — 



1. Aspects of the Earth. The Popular Account of some Familiar Geo- 

 logical Phenomena. New York, Charles Scribner's Sons, 1889, pp. xix. 

 and 344. Sixty-eight Illustrations.

The course in Elementary Physical Geography and Meteo- 

 rology (Natural History 1) was again in the hands of Professor 

 Davis. It was attended by seventy students. The increasing 

 development of laboratory methods in this course make the 

 employment of an Assistant desirable in the coming year. The 

 advanced course in the same subjects was attended by one 

 Graduate and one Senior. 



The most important additions to the collections of the Labo- 

 ratory during the year was a set of colored plaster models,
