ON THE ROCKS OF THE QUEBEC GROUP. 187 



Church road to the main road. It traverses this obliquely, a little 

 beyond the church, and its turn upon the synclinal axis is seen on 

 the north side of the road, about 400 yards beyond. In the lime- 

 stone of Guay's quarry there is a small notch-like turn, which serves 

 to augment somewhat its apparent volume ; a corresponding twist 

 is more conspicuous in the outcrop of band 3, and in band 2 it 

 assumes a still further prominence at y. These successive forms in- 

 dicate a plait in the stratification, commencing at the quarry, and 

 rapidly augmenting northeastwardly in the space of 350 yards. 

 The importance of its effect on the distribution of the strata would, 

 at this rate of increase, soon become considerable, and it serves to 

 show some of the complications of the neighborhood. 



Without going into detail, it is evident from the map that the 

 Middle Ridge is an anticlinal form, and that the South Ridge is 

 another. On this, the exposures of the bands 2 and 3 conspicuous- 

 ly mark the turn on the axis, as they do in the synclinal between 

 the ridges. It will be perceived that between the synclinal and 

 anticlinal axes, the outcrop of band 2 is represented as showing 

 a very sharp twist. The evidence of this is not quite satisfactory, 

 and the apparent arrangement may possibly be due only to a 

 swelling in the volume of the band, with parts obscured by drift. 



The Temperance Monument stands on band 1, with which are 

 associated some layers of sandstone. This band is easily traced 

 to the northeastward, across the fief Ste. Anne ; but between that 

 and the fault, it becomes broken down and obscured, and it will 

 require farther investigation. Nothing like it, nor indeed any con- 

 glomerate band has been yet observed following, in its relative place, 

 the sinuosities of band 2, where the strata are affected by the 

 synclinals and anticlinals that have been described. Eastward of 

 the fault, and northward of band 2, there is an exposure of conglo- 

 merate close upon the southeast side of the main road, the bearing 

 of which would carry it under the church of St. Joseph ; and two 

 years ago it was observed in an excavation for the foundation of a 

 house on the northwest side of the road, close by the church. In 

 the strike of these exposures, about 400 yards beyond the church, 

 there is a band of conglomerate, which continues in the same strike 

 for about a hundred yards. This strike would carry the band away 

 from those of the North Ridge, and gradually bring it towards those 

 of the Coast Ridge; and it appears probable that the bands of the 

 Coast Ridge may be only a repetition of some of those of the North 

 Ridge. The main band of the Coast Ridge is associated with sev- 

 eral beds of sandstone ; and from its great breadth it may possibly
