and angular, light coloured fragments lying with very 

 little evidence of bedding, in a dark matrix of the nature 

 of a coarse, quartz sandstone or quartzite. The embedded 

 fragments vary in size from very small up to one foot or 

 more in diameter, and when broken out from the matrix 

 may be seen to possess smooth, rounded, waterworn outlines. 

 As may be noticed in this and other exposures, certain beds 

 of the conglomerate are characterized by the uniformly 

 small size of the contained fragments, others by the relative- 

 ly large size of the fragments. The fragments consist 

 chiefly of limestone, the most abundant variety being a 

 dense, bluish-grey type. Pebbles and boulders of sand- 

 stone, quartzite, quartz, limestone conglomerate, sandstone 

 conglomerate, etc., are also present. 



- Towards the west end of the exposure of conglomerate, 

 a small body of dark shale is exposed on the roadside in 

 contact with the conglomerate. The same dark shale 

 or slate is exposed westward along the shore. Apparently 

 this locality is at the contact of the conglomerate with 

 the large body of shales extending to the south. If it be 

 true, as has been assumed, that the shales lie on the northern 

 limb of a syncline, then the conglomerate and quartzite 

 band to the north belongs to a horizon lower than that of 

 the body of similar strata forming the ridge southwest of 

 Bic station. 



Westward from the exposure of conglomerate, the high- 

 way approximately follows the boundary between the 

 conglomerate and quartzite on the north, and the shales 

 on the south. The line of contact between the two 

 divisions is very irregular in detail probably as a result of 

 deformation that took place during the folding and sub- 

 sequent faulting of the measures when, doubtless, the 

 shales as a whole acted as a relatively plastic body and the 

 conglomerates and quartzites as a brittle mass. Along this 

 portion of the road, the quartzite beds associated with the 

 conglomerates, are exposed. The quartzite composes the 

 bulk of the formation. It is usually fine grained but in 

 places is sufficiently coarse to be termed a grit and is 

 composed almost exclusively of rounded quartz grains 

 in a silicious matrix. 



No rocks outcrop along the road where, after passing 

 through a cut in conglomerate, it bends to the eastward 

 along the edge of the low ridge. The quartzites and con- 

 glomerates in this ridge are vertical or dip steeply to the
