202 THE ICE AGE IN CANADA. 



erable depth, and present certain remarkable modifications. 

 The section observed at this place is as follows : 



ft. in. 



1. Hard gray laminated clay, Foraminifera and Leda, in thin 



layers 7 



2. Red layer, in two bands 6 



3. Sandy clay 1 



4. Gray and reddish clay 9 



5. Hard buff sand, very fine and laminated 15 



6. Sand with layers of tough clay, holding glaciated stones, and 



very irregularly disposed 4 



7. Fine sand 1 



8. Gray sand, with rounded pebbles, and laminated obscurely 



and diagonally 4 



9. Fine laminated yellow sand 3 



10. Gravel 4 



11. Very irregular mass of laminated sand, with mud, gravel, 



stones and large boulders 12

The whole of these deposits, except the Leda clay, are 

 very irregularly bedded, and are apparently of a littoral 

 character. They seem to show the action of ice in shallow 

 water before the deposition of the Leda clay. The only 

 way of avoiding this conclusion would be to suppose that 

 the underlying beds are really of the age of the Saxicava 

 sand, and that the Leda clay has been placed above them 

 by slipping from a higher terrace ; but I failed to see good 

 evidence of this. A little farther west, at the gravel pits 

 dug in the terrace for railway ballast, a deep section is 

 exposed, showing at the top Saxicava sand, and below this 

 a very thick bed of sandy clay with stones and boulders, 

 constituting apparently a somewhat arenaceous and par- 

 tially stratified equivalent of the boulder-clay. A little 

 above this place, at the brick-works, the Saxicava sand 

 is seen to rest on a highly fossiliferous Leda clay, which
