188 ON THE ROCKS OF THE QUEBEC GROUP. 



be capable of division into more tban one mass of conglomerate. 

 To the south westward of the extreme point to which this band has 

 been traced, there occurs in the cliff, to the southeast of the Lower 

 Ferry, the band A ; one of those referred to in the description of 

 1860. Its exact relation to the other bands has not yet been 

 satisfactorily determined. 



Southward of A 3 you will remark A 4 , and you will perceive 

 that these two bands somewhat converge to the southwest, in which 

 direction they are not traceable for over a quarter of a mile. At 

 the time of the previous description, it was left undecided whether 

 these were to be considered distinct bands, or a repetition of one 

 another. They are now assumed to be distinct. On the Middle 

 Ridge, the band 4, at P, is followed by B 1 ; which is a band of slate 

 with nodules of limestone. On the North Ridge its place would 

 be between A 3 and A 4 . It would therefore be band 5, and A 4 

 would be band 6. The bands 7, 8, and 9 succeed on the north 

 side of the Middle Ridge, the band 9 being B 2 of the former des- 

 cription ; like B 1 , it is composed of slate studded with nodules of 

 limestone. This band appears to have a considerable develop- 

 ment southwestwardly, in a long shallow trough-like form, ex- 

 tending to the Grande Cote road. From this, its outcrop returns 

 on the south side of the Middle Ridge anticlinal, and points to B 3 ; 

 which however differs from it in character, having a base of mag- 

 nesian limestone instead of slate. What is seen of the band B s 

 is broken into three portions by transverse faults. It is evidently 

 on the south side of the Middle Ridge anticlinal, and may corres- 

 pond with band 8, but this has not yet been satisfactorily made 

 out ; nor has it yet been found possible to arrange the complicated 

 exposures to the southeast of it, on the South Ridge. 



On the southwest boundary of the fief Ste. Anne, near the 

 quarry there indicated, the beds appear to be dislocated on the 

 north side of the Middle Ridge anticlinal, by faults, which do not 

 affect the outcrops on the south side. These faults may be small 

 breaks accompanying twists in the strata, the connecting parts of 

 which may be concealed by drift ; but it would require additional 

 facts to make their arrangements certain. Though the number 

 of bands is assumed to be nine, some of them may be repetitions 

 through the effect of plaits suddenly starting up, like that at y, or 

 through undetected faults running with the stratification. The 

 distribution of the outcrops in the southwest part of the South 

 Ridge shows the very complicated character of the disturbances, 

 and is a warning against over-confidence in respect to minute de-
