in terraces and recent small canons now 

 submerged. Also the modern coralline for- 

 mations and harbors are notable. 



On the completion of the paper the Society 

 adjourned its business session until the 

 following morning. 



In the evening many members attended 

 Professor Wm. Libbey's lecture on Green- 

 land, and afterwards the reception which 

 was hospitably tendered the visiting socie- 

 ties by the Johns Hopkins University in 

 McCoy Hall. On reassembling Friday morn- 

 ing the council presented some minor points 

 of business, and Mr. J. S. Diller, the chair- 

 m.an of the committee on photographs, read 

 his annual report. It showed that some 

 1,200-1,500 photographs of geological phe- 

 nomena and scenerjf had been presented to 

 the Society, the same being on exhibition in 

 the hall. The negatives of the U. S. Geol. 

 Survey in many instances and also those of 

 not a few geologists have been made acces- 

 sible to the fellows for prints at cost. Mr. 

 Diller finally tendered his resignation, which 

 was accepted with regret. Mr. G. P. Mer- 

 rill, of the U. S. National Museum, was ap- 

 pointed to the vacancy. The committee now 

 consists of G. P. Merrill, W. M. Davis and 

 J. F. Kemp. 



The first paper on the programme was — 

 11. Observations on the Glacial Phenomena 



of Newfoundland, Labrador and Southern 



Greenland. G. Frederick Weight. Ob- 



erlin, Ohio. 



N"ote was made of the direction of the 

 glacial scratches in ITewfoundland and of 

 the evidences of a preglacial elevation of the 

 island ; also of the contrast between the 

 flowing outlines of the coast range of moun- 

 tains in Labrador and the jagged character 

 of the coast range of Southern Greenland. 

 A description was also given of the projec- 

 tion of the inland ice which comes down to 

 the coast near Sukkertoppen, in Lat. 65° 

 50', and of the phenomena which indicate 

 the former extension of the Greenland ice 



far beyond its present boundaries. Still, 

 the bordering mountains were never cov- 

 ered with ice. 



12. Highland Level Gravels in Northern 

 Neio England. C. H. Hitchcock, Han- 

 over, IST. H. 



Eecent observations prove the existence 

 of a glacial lake in the basin of Lake Mem- 

 phremagog, whose beaches exceed a thou- 

 sand feet above sea level, and others 

 1,500 feet above sea level in northern New 

 Hampshu-e. The author wished to present 

 a preliminary notice of what may prove to 

 be of great service in a more exact defini- 

 tion of glacial woi"k in New England and 

 Canada. 



The paper was discussed by Professor J. 

 W. Spencer, who spoke of his ovm. studies 

 in the same region. 



During the reading of the following six 

 papers the petrographers and mineralogists 

 adjourned to the room above and listened 

 to the reading of papers of a petrographic 

 character, as subsequently outlined. The 

 principal session then listened to the follow- 

 ing: 



13. Variations of Glaciers. Harry Field- 

 ing Reid. 



The paper called attention to the desira- 

 bility of keeping accurate records of the 

 movements of glacial ice wherever possible. 

 A committee was appointed to further this 

 movement at the Geological Congress in 

 Zurich last summer, and the writer urged 

 the importance of the work, especially as 

 regards our western glaciers. 



] 4. Discrimination of Glacial Accumulation 

 and Invasion. Warren Upham, Somer- 

 ville, Mass. 



The accumulation of ice-sheets bj^ snow- 

 fall on their entire area was discriminated 

 from an advance or invasion bj^ the fi-ont 

 of the ice, extending thus over new terri- 

 tory. The former condition is shown to 

 have been generallj' prevalent, on the gia-
