112 PEOCEEDINGS OF THE BOSTON MEETING 



Wisconsin ice-caps, and around the ice-caps of other continents. Questions 

 arise as to the possibility of evidence from the warped strands of the lakes 

 ancestral to the existing Great Lakes, the submarine channel of the Hudson 

 River, the "deeps" of the Susquehanna River, the abandoned channels of the 

 Ohio Valley, and the belt marginal to the Scandinavian ice-cap. These ques- 

 tions are raised as means of advertising a problem which clearly needs, for 

 definite solution, cooperative attack by many specialists.

RECEIPT WORLD-WIDE SINKING OF OCEAN LEVEL 

 BY EEGINALD A. DALY 



{Abstract) 



In the Gulf of Saint Lawrence, along the New England coast, in Florida, 

 and in Samoa field observations have shown that the sealevel has recently 

 fallen about 20 feet. In each region the shift of level has been practically 

 uniform. This regional uniformity and the accordance of the shifts registered 

 in four mutually distant areas have prompted explanation by a general fall 

 of ocean level to the extent of about 20 feet. Evidence from the British Isles, 

 the Atlantic seaboard south of New England, the West Indies, South America, 

 New Zealand, Australia, and the Pacific islands seems to strengthen the ex- 

 planation offered for the facts personally observed in the field. 



Presented Avithont mann script. 



Discussion 



Dr. E. O. HovEY cited observations on a 15-20-foot raised beach noted at 

 many places on the Greenland coast from Cape York to Etah. 



SUBMERGENCE AND POST-GLACIAL UPLIFT IN NEW HAMPSHIRE 

 BY JAMES WALTER GOLDTHWAIT 



(Al)stract) 



Recent tield-M^ork in the southeastern part of New Hampshire affords dis- 

 tinct evidences of the late glacial, or "Champlain," marine submergence and 

 reelevation of that district. Delicate yet unmistakable shoreline features, 

 such as curved bars built between drumlin islands and short-hooked spits at- 

 tached to the rear ends of these islands, occur not only in Stratham and 

 Dover, where they are nicely shown by contours on the new Dover quadrangle, 

 but also in North Hampton, Kensington, and Seabrook, where earlier and less 

 accurate topographic sheets offer no suggestion of their presence. Outwash 

 aprons associated with water-laid moraines in the Dover region and several 

 cliffed drumlins agree with the better evidence of the raised beaches in fixing 

 the amount of the postglacial uplift here at about 150 feet. 



From the coastal district inland the old marine and estuarine deposits give 

 way to disconnected valley trains and local wash plains whose levels appear
