GEOLOGY AND GEOGBAFHY AT THE AMERI- 

 CAN ASSOCIATION MEETING. 

 I. 



By the invitation of Section E (Geology 

 and Geography) of the American Associa- 

 tion, meetings of the Geological Society of 

 America and of the National Geographic 

 Society were held with this Section, the 

 former in three sessions on Tuesday fore- 

 noon, afternoon and evening, August 23d, 

 and the latter on Thursday afternoon, the 

 25th. These sessions, and those of Section 

 E, were held in the lecture room of the Bos- 

 ton Society of Natural History, excepting 

 the final session, on Friday forenoon, which 

 was held in the geological lecture room of 

 the Museum of Comparative Zoologj', in 

 Cambridge. 



The address by the Vice-President of 

 Section E, Professor Herman L. Fairchild, 

 of Eochester, N. Y., on 'Glacial Geology 

 in America,' was presented on Monday af- 

 ternoon. It reviewed the history of the 

 development of this branch of geology in 

 the United States and Canada, concluding 

 with the assertion that the origin of the 

 North American drift through the action of 

 a continental ice-sheet is now, after fifty 

 years of exploration and discussion, as fully 

 proved as any of the principles of geology. 

 It is published in the September American 

 Geologist and in the Scientific American Sup- 

 plement for September 3d, 10th and 17th. 



In the opening session of Section E, with 

 the Geological Society, on Tuesday fore- 

 noon, short memorial addresses on the life 

 and work of the late Professor James Hall 

 were given by Professors Emerson, Fair- 

 child and Niles, and by Dr. Horace C. 

 Hovey, noting Hall's earnestness in boy- 

 hood and youth to acquire knowledge of 

 geology and allied sciences, walking twenty
