of alternating beds of coarse and fine quartzite, and con- 

 glomerate either disposed vertically or dipping to the 

 south. At the foot of the northern slope, the quartzite 

 and conglomerate are interbedded with black slate, while 

 along the railway line the strata are entirely composed 

 of black slates. The interbedding of the quartzites and 

 slates along the boundary of the two divisions and the 

 absence of any appearances of structural unconformity 

 indicate that the slate series and the quartzite series are 

 conformable, while the uniform southerly direction of 

 dip in the eastern part of the ridge and an open synclinal 

 fold developed to the south indicate that the quartzite 

 series overlies the black slate division. 



The road leading southward from Bic station ascends a 

 gently rising slope and passes a few hundred feet to the 

 east of the abrupt end of the quartzite ridge. Along the 

 roadside are exposed nearly vertical beds, striking west- 

 ward, of purple weathering dark shales; these shales 

 at the southern end of the exposure contain thin beds 

 (i to 6 inches; 2 cm. to 15 cm.) of fine-grained sandstone 

 and these dip southward at an angle of 6o°. The slates 

 strike directly towards the quartzite ledges exposed along 

 the east slope of the hill and, evidently, must be separated 

 from them by a fault plane. 



No further outcrops occur along the road for some 

 distance. As the road is followed southward, the out- 

 cropping ledges of white quartzite to the west, may be 

 seen to approach closer and closer to the road. Just 

 beyond where a branch road leads to the west and close 

 to the Bic river, an exposure of dark weathering, greenish 

 slate occurs on the roadside while, just beyond at the turn 

 of the road, are outcrops of quartzite and conglomerate. 

 These two exposures are believed to lie on opposite sides 

 of the above mentioned fault plane. In the general 

 area to the east of the fault plane, — along the river, over 

 the ridge on the southern side of the river, and elsewhere, 

 only dark slates and the associated thin beds of sandstone 

 are exposed. West of the fault plane the strata are 

 almost entirely light coloured quartzites and conglom- 

 erates. 



At the bridge over the river the quartzite beds are 

 displayed in the crown of an anticline. On the river below 

 the bridge, the quartzites dip southerly at angles of 20° 

 to 30 , while those above the bridge dip at low angles to
