THE AMERICAN ASSOCIATION FOB THE 

 ADVANCEMENT OF SCIENCE. 

 SUMMER MEETING OF SECTION E. 



Section E of the American Association for 

 the Advancement of Science will hold a sum- 

 mer meeting at Syracuse, N. Y., July 19-22. 

 Arrangements have been made for making the 

 meeting enjoyable and profitable to all mem- 

 bers of the section. The vicinity of Syracuse 

 is one of great interest in several branches of 

 geology: the fossiliferous rocks of the New 

 York series are well exposed in many ravines ; 

 the surface shows most of the phenomena of 

 chief interest in glacial geology; the pre- 

 glacial and the modern topography have been 

 worked out by specialists, and the economic 

 geology of the district is important. The chief 

 study in the field during the meeting will be 

 the gorges and lakes of the glacial drainage, 

 which are the most novel features of the dis- 

 trict. 



In making its plans for the meeting the 

 sectional committee has accepted the cordial 

 invitation of the committee having in charge 

 the joint summer courses in geology for several 

 eastern universities and colleges to hold a 

 meeting in conjunction with the summer 

 school.
