H0NEYMAN GEpEOGY OF ANTIGONISHE COUNTY. 6T 



The members of the upper series are arranged in a synclinal 

 form, having a northern and a southern side. These are irregu- 

 larly distributed over the area. Regarding the area as divided into 

 eastern and western by section No. 7, the Arisaig Pier section. 



The lower member A is confined to the eastern division, begin- 

 ning between 3 and 4 and ending with the dividing line. The 

 second B is principally in the eastern division. It begins with 

 section 4 and ends in the western division, between the dividing 

 line and Smith's Brook, section No. 8. It is wholly on the 

 northern side of the synclinal. The third member B' occurs on 

 both sides of the synclinal, in the eastern division. In the western 

 division it occurs on the northern side, beyond Smith's Brook 

 section. 



The fourth member C occurs in the eastern division on the 

 southern side of the synclinal, beginning with section 3, McNeil's 

 Brook. It occurs next in section 5. It then occurs on the northern 

 side of the dividing line and extends beyond McAdam's Brook 

 section and beyond Moydart point to the vicinity of McAra's Brook. 

 The fifth member D occurs to the east of the dividing line on the 

 southern side. It occurs in the western division and north side in 

 McAdam's Brook section, and its principal part is in the shore 

 section, between Moydart point and McAra's Brook section. The 

 last member E appears on the south side of the dividing line, the 

 north side of McAdam's Brook section, and in the whole of McAjra's 

 Brook section, north and south sides of synclinal. 



These facts are important as shewing'the irregularity of occur- 

 rence and conditions of formations even in a very limited area. 



Correlation. 

 (I). — The Lower Arisaig series has its corresponding rocks in 

 the I. C. R. section of the Cobequids. 



On the Colchester side the syenites and diorites of the centre are 

 succeeded fey petrosiliceous rocks, jaspers, gneisses, diorites (cryp- 

 to-crystalline) and calcite, to which may be added the marbles of 

 Five Islands. This series has its counterpart on the Cumberland
