Instruction in Summer Schools. 



15. Geol. S. 1. An elementary course, beginning July 6th and lasting 

 five weeks, was held in Cambridge, in the Geological Laboratory, by T. W. 

 Harris and H. B. Kummel. This course is parallel to Geology 5, as given 

 in the University. Meetings were held five days each week, with field- 

 work in the vicinity of Cambridge. One excursion was made to the Cam- 

 brian and Carbouiferous deposits in the town of Attleborough, Mass. 

 This course was attended by sixteen students. 



16. Geol. S. 2. An advanced course in field-work on the geology of 

 the stratified rocks was given at the following places during the summer 

 of 1892. The class met at Utica, N. Y., July 7, under the charge of 

 T. W. Harris. On July 20, the class moved to Catskill, N. Y., and on 

 the 4th of August went to Meriden, Conn., where the work of the class 

 was in charge of H. B. Kummel. This course closed on August 19. 

 Twelve students attended the course. 



17. Geol. S. 3. A half-course in independent field investigation and 

 geological surveying, under the supervision of N. S. Shaler, W. M. Davis, 

 J. E. Wolff, and T. W, Harris. Two parties of students began work in 

 this course in Eastern Massachusetts in the summer of 1892, one with 

 Dr. Harris on the Structure of the Boston Basin, and a second with J. B. 

 Wood worth on the Carboniferous and Cambrian Rocks of Norfolk and 

 Bristol Counties. The work in this course lasts for six weeks, and will 

 be completed before October 1st. Six students have taken this instruction. 



Additional Instruction. 



During the year, the students in the advanced courses at- 

 tended regular Tuesday evening meetings in the Geological Labo- 

 ratory, which were designed to serve the purpose accomplished 

 by the Seminaria of the German Universities. A number of the 

 papers read at these conferences have been announced in the 

 College Calendar. In addition to the papers presented by stu- 

 dents, a paper was read by Baron de Geer, of Sweden, " On the 

 Changes of Level on the Atlantic Coast."
