PHYSIOGRAPHIC EVIDENCE OF RECENT SUBSIDENCE ON THE COAST OF 



MAINE 



BY CHARLES A. DAVIS 



(Abstract) 



For several years the author has been collecting evidence which seemed to 

 him to prove a recent subsidence of the North Atlantic coast, still in progress. 



Some of these evidences have already been presented before this Society. 

 During the summer of 1915 some attention has been given to the physiographic 

 evidence of subsidence presented by certain beaches in southwestern Maine, 

 where an ancient beach was found almost buried in a salt marsh, which clearly 

 must have been formed subsequent to the beach. The unaltered crest of this 

 old beach is several feet lower than that of the modern beach of exactly the 

 same type. Other beaches with multiple ridges in the same region give note- 

 worthy confirmation of the evidence furnished by the one mentioned. 



Some other physiographic evidence of subsidence now in progress was pre- 

 sented, and this was shown to be fully in harmony with other types of evidence 

 already presented in former papers. 



Presented in abstract extemporaneously. 



PHYSIOGRAPHIC NOTES ON THE WHITE MOUNTAINS 

 BY DOUGLAS W. JOHNSON 



(Abstract) 



The paper presents certain observations made during a brief visit to the 

 White Mountains in the summer of 1914. 



The origin of the felsenmCer or block moraine, the date of cirque forma- 

 tion, and the position of the New England peneplain with reference to the 

 mountains are briefly treated. 



Presented by title in the absence of the author. 



POSITION OF THE NEW ENGLAND UPLAND IN THE WHITE MOUNTAINS 

 BY ARMIN K. LOBECK * 



(Abstract) 



An attempt to trace the New England peneplain from the base of Mount 

 Monadnock to the White Mountains has led to the unqualified conclusion that 

 in the latter region the peneplain lies near the base of the mountains, and that 

 the mountains represent monadnocks rising far above the badly dissected 

 upland surface. In addition to the field evidence, a study of the topographic 

 sheets east of the mountains and Hitchcock's Atlas of New Hampshire, by 

 means of projected sections, decisively supports the conclusion. 



Presented in abstract extemporaneously.
