[N. S. Vol. XXVI. No. 665 



were set forth. Tile invariable association 

 even of the graphite-bearing pegmatites 

 with Grenville sediments was emphasized, 

 and the schists seemed most probably a 

 metamorphosed carbonaceous sediment, or 

 one which had been impregnated with a 

 heavy oil. 



The party next visited the potholes on 

 Indian Kettles point, two miles north of 

 Hague. These interesting relies of the 

 glacial epoch are on a rocky point, and 

 fifteen feet or more above the present lake. 



In the evening a brief exposition of the 

 local geology and physiography was given 

 by J. F. Kemp, and illustrated by manu- 

 script maps. The sediments of the Gren- 

 ville series are the oldest rocks, now greatly 

 metamorphosed. A syenitie series of erup- 

 tives, the most extensive of the local forma- 

 tions, succeeded the Grenville, and these are 

 also greatly metamorphosed. There are 

 also rocks intermediate between syenite 

 and gabbro; true gabbros and granites. 

 Lastly came a few basaltic dikes. There 

 are no late Paleozoics in the reigon, but the 

 Potsdam and Beekmantown are near or in 

 the Lake George basin. The physiography 

 was believed by the speaker to be chiefly 

 due to block faulting, which was freshened 

 up by the ice-sculpturing of the glacial 

 epoch. 



The next morning the party proceeded to 

 Hiiletts, and visited an igneous contact on 

 Tafts point. At Huletts dock interesting 

 pegmatites and the effects of shearing and 

 faulting were seen. Three sets of displace- 

 ment could be detected. The party were 

 kindly taken about the lake by Dr. Smith 

 Ely Jelliffe in his launch, adding greatly 

 to their pleasure and profit. After lunch 

 in the-charniing summer home of Professor 

 and Mrs. Kemp the members continued 

 south through the lake and dispersed. 



The following resolutions were passed 

 by Section E : 



Section E of the American Association 



for the Advancement of Science in sum- 

 mer session assembled desires to express its 

 high appreciation and gratitude 



To Dr. John M. Clarke and the members 

 of the New York Survey for valued ad- 

 vice in the preparations for this meeting, 

 and for guidance during its progress; 



To Professor and Mrs. George H. Hud- 

 son, to the Honorable Smith M. Weed, and 

 to Professor and Mrs. J. F. Kemp for most 

 gracious hospitality ; and 



To the governing board of the Ghamplain 

 Assembly for giving us an attractive and 

 convenient home during our session, and 

 the opportunity to become acquainted with 

 a valuable and interesting educational in- 

 stitution.
