During the summer of 1887, twenty-two students, eight of 

 whom had been previously trained in the classes of the Univer- 

 sity, received systematic training in field-work. Sixteen of these 

 persons were included in the Summer School of Geology, which 

 was taught in Cambridge, at two points in Southern Connecticut, 

 in the Catskills, and at North Adams, by the officers of this 

 department. 



During the year the following papers of a scientific nature 

 have been published by N. S. Shaler : — 



1. The Fluviatile Swamps of New England. American Journal of 

 Science, March, 1887. 



2. Preliminary Report on the Sea-coast Swamps of the Eastern United 

 States, in the Sixth Annual Report of the Director of the U. S. Geologi- 

 cal Survey. 



3. Notes on Taxodium distichum, or Bald Cypress. Memoirs of the 

 Museum of Comparative Zoology, Vol. XVI., No. 1. 



4. On the Original Connection of the Eastern and Western Coal Fields 

 of the Ohio Valley. Memoirs of the Museum of Comparative Zoology, 

 Vol. XVI., No. 2. 



5. Four papers on the study of Field Geology, in the Boston Journal 

 of Science. 



6. On the Stability of the Earth. Scribner's Magazine, Vol. I., No. 3. 



7. On the Forests of North America. Scribner's Magazine, Vol. I., 

 No. 5. 



8. On the Instability of the Atmosphere. Scribner's Magazine, Vol. 

 II., No. 2. 



9. On the Origin and Nature of Rock Gas. The Forum, April, 1887. 



During the past year, the in-door work of Professor W. M. 

 Davis has been carried on in the Lawrence Scientific School 

 building, on account of lack of room in the Museum ; but it is 

 hoped that this arrangement may be only temporary. His Ele- 

 mentary Course in Meteorology and Physical Geography (N. H. 

 1) was attended by twenty-eight students ; the Advanced Course 

 (N. H. 20), by two students. It is proposed in the coming year 

 to give even more attention than heretofore, in the course in 

 Physical Geography (Physiography), to the description of the 

 form and development of geographic types, thus introducing into 

 geography the principle so successfully employed at present in 

 biological teaching. 



The share of Mr. Davis in geological instruction has been
