(c) Dark slates, in places weathering with a purplish 

 colour; occasional relatively thin beds of limestone 

 conglomerate. 



(d) Interbedded quartzites and conglomerate. 



(e) Dark slate. 



(f) Conglomerate and quartzite. 



The total thickness of the series displayed must be 

 considerable, perhaps in the neighbourhood of 3,500 feet 

 (1,066 m.), but no reliable estimate of the thickness has 

 been formed. Regarding the age of the strata it may be 

 stated that it cannot be older than Lower Cambrian since 

 the fauna of the limestone pebbles in the conglomerates 

 is of this age. Presumably the series is at least as young 

 as Middle Cambrian and possibly still younger. It is 

 noteworthy that lithologically the quartzites are identical 

 with the quartzite or quartzose sandstone displayed at 

 Riviere du Loup below High Falls. The somewhat scanty 

 fossiliferous evidence obtained at Riviere du Loup indicates 

 that there the quartzite is of Lower Ordovician age ; possibly 

 the strata at Bic are of about the same age.

 SUBMERGENCE.

Just to the west of Bic railway station one may see a 

 record of glaciation towards the north, — according to 

 Chalmers' interpretation — by the ice from the Appalachian 

 highlands. A well formed roche moutonnee close beside 

 the track is severely scrubbed on the south side and torn 

 and roughened on the north. Among the ledges of lime- 

 stone and conglomerate which outcrop in the hills south
