OCCURRENCE OF GLACIAL DRIFT ON THE MAGDALEN ISLANDS^ 

 BY J. W. GOLDTHWAIT 



(Abstract) 



These islands, which lie in the Gulf of Saint Lawrence, 50 miles northwest 

 of Cape Breton, have been reported by James Richardson (1881), Robert 

 Chalmers (1895), and Dr. John M. Clarke (1910) to be non-glaciated. Dur- 

 ing a rapid reconnaissance last summer the discovery was made of glacial 

 boulder-clay containing soled and striated stones of both local and foreign 

 derivation. Some of this evidence of glaciation will be exhibited and its value 

 discussed in the face of the seemingly contradictory evidence presented by 

 earlier observers.

EVIDENCE OF A GLACIAL ICE-DAM IN THE ALLEGHENY RIVER BETWEEN 

 WARREN, PENNSYLVANIA, AND TIONESTA, PENNSYLVANIA 



BY G. FREDERICK WRIGHT 



(Ahstract) 



The high level glacial gravel deposits on the east side of Conewango Creek 

 at Warren, Pennsylvania, which were originally supposed to rest on a rock 

 shelf, prove on closer examination to be continuous deposits from the bottom 

 of the valley up. The course taken by the glacial stream which laid down 

 these glacial deposits has been a puzzling one, until in a recent examination 

 of the locality it was discovered that the more southern one of these gravel 

 terraces, beginning near the golf links east of Warren, runs for a mile or more 

 up the Allegheny Valley to the mouth of Glade Run, thus showing that the 

 current was aiming toward the well known Tionesta outlet, in which there
