Appendix. 



In the description which followed upon the reading of this paper 

 Dr. L. W. Bailey called attention to the facts which both in New 

 Brunswick and Nova Scotia indicate the former higher elevation of the 

 Aoadian region in pre-Glacial and Glacial times. 



As regards New Brunswick this is indicated not only by the exten- 

 sion of the channels of the St. John and other rivers debouching into 

 the Bay of Fundy, as indicated by soundings and the arrangement of 

 isobaric lines upon the north side of depression, but also by the fact 

 that the present river St. John, as indicated by the depth of the 

 Pleistocene clays at Fredericton, eighty miles from the mouth, is flow- 

 ing at a level at least 200 feet above its former rock bottom, and again 

 by the fact, recently pointed out by Prof. Ganong, that the streams 

 which drain the eastern sea-board of New Brunswick at one time ex- 

 tended across Northumberland Straits and were coincident with the 

 more marked valleys now indenting the coast of Prince Edward Island, 

 these being tributary to the main channel of the St. Lawrence then 

 traversing the entire length of the latter. 



In Nova Scotia like conditions are indicated by the fiord-like 

 irregularities of the present southern or Atlantic shore and of its sub- 

 merged platform, as indicated by Prof. Poole, but also by the evidences 

 of unusual glaciation there exhibited, as shown by the character and 

 extent of the moraines, eskers and kames met with, and especially the 

 size and depth of glacial troughs, which, in some instances, traverse 

 the hard quartzites of the Cambrian system with a depth of not Jess 

 than twenty feet! Photographs of the latter were exhibited to the 

 members of the section.
