will be visited. The quarry lias produced in 

 recent years a greater variety of interesting 

 minerals than any other in this locality, and 

 is always an attraction to visiting mineralo- 

 gists. 



Saturday the party will devote its attention 

 to the faulting within the Triassie valley. 

 The fault-line between the Lamentation 

 Mountain block and the Hanging Hills block 

 will be the particular study. Step faults and 

 drag dips are frequent along the fault-line and 

 give clear evidence of the magnitude of the 

 faulting movements. 



On Friday evening Professor W. M. Davis 

 will speak on the Connecticut Triassie area as 

 a whole. Professor W. 'N. Eice will then out- 

 line the details of the Saturday excursion and 

 Professor W. G. Foye discuss the pegmatite 

 quarries in the vicinity of Middletown. Im- 

 mediately before these talks a luncheon will be 

 served to the visiting geologists by Wesleyau 

 University. 



A collection of minerals f ro-m the pegmatites 

 including one of the largest known collections 

 of uraninites in the country will be on exhibi- 

 tion. 



A cordial invitation is extended to all teach- 

 ers and graduate students of geography and 

 geology in the high schools, normal schools and 

 colleges of New England.
