1. — That the Lower Arisaig series is distinct from the Middle series. 

 2. — That by volcanic agency the lower series was elevated above 



the sea, prior to the formation of the middle scries. (?) 

 3. — That while the latter is regarded as Lower Silurian the former 



may be regarded as Cambrian (?) or Laurentian, tuili" 



palaeontology has decided the question. 



In my paper on the I. C. R. section, (Transactions 1873-4), 

 I correlated the Wentworth section with a section of the Wales" 

 Silurian rocks, according to Professor Ramsay's authority. The 

 difference between the Wales and I. C. R. section, now seems to 

 be that the latter seems to have a greater range downward. 



Morristown Township. — {Continuation of Section 12.) 



Traversing the shore of Northumberland Strait, eastward of the 



Arisaig Township. Before reaching the north side of Cape George 



we pass out of the metamorphic (?) middle, and upper silurian slates 



into lower carboniferous conglomerate. This conglomerate varied 



by a projecting trap-rock (diorite), here and there, especially at the 



point of the Cape, constitutes the section to the south-east side of the 



Cape in St. George's Bay. These form the north-east part of the 



north side of the northern carboniferous area of the County. 



The remaining part of this side westward extending to the Arisaig 

 or o o 



mountain (Sugar Loaf), is separated from the strait by the meta- 

 morphic slates and the Lower Arisaig series of the section already 

 described. In the part that overlies the Lower Arisaig series there 

 occurs lower carboniferous limestone. Continuing the section on 

 St. George's Bay we have coarse sandstones, with shrinkage cracks, 

 and sandstones with scales of paloeoniscu. At Graham's Brook 

 we found flora in the sandstone, casts of lepidodendron, &c. 



Between this and the north side of the Morristown lakes there is 

 no outcrop of interest — the ground being flat. From the Cape to 

 Morristown lakes the carboniferous series ascends ; after that there 

 comes another series which descends. The Morristown lakes' strata 

 include a coal field — Daioson's Acadian Geology, Ed. 1867. This 

 coal field has a history. —
