THE AMERICAN ASSOCIATION FOR THE 



ADVANCEMENT OF SCIENCE 



SECTION E~GEOLOGY AND GEOGRAPHY 



In spite of the fact that Section E held 

 a summer field meeting^ at Plattsburg, 

 N. Y., during the week of July 3 last, the 

 interest of its members in the winter 

 meeting showed no abatement. A large 

 niunber of its geological members attended 

 the meeting of the Geological Society of 

 America at Albuquerque, and consequently 

 there was not a large attendance of those 

 whose special interest is geology. But, on 

 the other hand, the Association of Amer- 

 ican Geographers met in Chicago at the 

 same time as Section E, and this attracted 

 a large number of geographers, many of 

 whom are members of the section. 



Immediately after the general session of 

 the association, the Association of Amer- 

 ican Geographers and Section E held a 

 joint meeting for the purpose of arranging 

 the program, after which the two organiza- 

 tions separated. The geological members 

 of the section held six sessions in the 

 Walker Museum, University of Chicago, 

 during Tuesday, "Wednesday and Thurs- 

 day, with the vice-president of the section 

 presiding, and the geographical members 

 met with the American Geographers, ex- 

 cept during the early portion of Wednes- 

 day afternoon, when the entire section met 

 to listen to Professor Chamberlin's paper 

 on the influence of the tides. 



At the first meeting of the section Pro- 



• An account of the summer meeting is printed 

 in Science, No. 665, pp. 397-404, Sept. 27, 1907.
