Thames River Terraces. F. P. Gulliver, 



Southboro', Mass. 



Cuts have recently been made for a new 

 line of railway on the east bank of the 

 Thames river between New London and 

 Norwich. They expose the structure of 

 many terraces which were regarded as 

 Champlain deposits by the late Professor 

 J. D. Dana, and which were referred to the 

 post-glacial, flooded rivers. The presence 

 of eskers at lower levels has, however, al- 

 ways been a fact difficult of explanation on 

 this hypothesis. The railway cuts expose 

 many delta lobes of fine sand which point 

 down stream and toward the sides of the 

 old vallejr and rest upon its covering of 

 till. In instances their axes point up side 

 valleys and away from the central axis of the 

 main valley. The fine sand is covered by 

 coarse boulders, such as are found in front 

 of Alaska glaciers. The speaker explained 

 them as due to a retreating glacier which 

 filled the center of the main valley and dis- 

 charged its waters and sediment laterally 

 as well as longitudinally. This raised the 

 question of possible side-ponds to the glacier, 

 at one or several altitudes and of the cor- 

 I'esponding new interpretation of the ter- 

 races that would follow as a result of the 

 suggestion. 



The Gold-hearing Veins of Bag Bay, Western 

 Ontario. Petee McKellar, Fort Wil- 

 liam, Ont. 



The object of this paper is to show the 

 peculiarities of the gold-bearing veins in the 

 granite area at Bag Bay, Shoal Lake, west 

 of the Lake of the Woods, Ontario. These 

 veins are characterized by the smallness of 

 the quartz fissures compared with the quan- 

 tity of valuable ore they yield under devel- 

 opment. The paper was read by Robert 

 Bell in the absence of the author. At its 

 conclusion the following were read by title :
