194 THE ICE AGE IN CANADA. 



present level; and in the meantime the high cliffs now 

 fronting the coast must have been cut out of the rocks of 

 the Quebec group. 



The order of succession of beds, as seen in the banks of 

 the Little Biviere-du-Loup, may be stated as follows, in 

 descending order : 



1. Large loose boulders, mostly of Laurentian rocks, seen 



in the tops of ridges of rock and gravel. One angu- 

 lar mass of Quebec group conglomerate was observed 

 ninety feet in circumference and ten to fifteen feet 

 high. Near it was a rounded boulder of Anorthosite 

 from the Laurentian. 13 feet long. 



2. Stratified sand and gravel resting on the sides of the 



ridges of rock projecting through the drift. Thick- 

 ness variable. 



3. Stratified sandy clay and sand with Tellina Grcenlandica 



and Buccinum. 10 feet. 



4. Gray clay and stones. Rhynconella psittacca, and 



Terebratulina ^ntzbergensis, &c, L foot or more. 



5. Gray clay with large stones, often covered with Bryozoa 



and Acorn-shells. Tellina calcarea very abundant, 

 also Leda arctica. 3 feet. 



6. Tough, hard, reddish clay, with stones and boulders, 



passing downward into boulder-clay, and holding 



Leda arctica. 6 feet or more. 



It was observable that the boulders were more abundant 

 on the south side of the ridges than on the north ; and 

 between Kiviere-du-Loup and Quebec there are numerous 

 small ridges and projecting masses of rock rising above 

 the clays, which generally show the action of ice on their 

 N.E. sides ; while the large boulders lying on the fields are 

 seen to have their longer axes N.E. and S.W.
