45S HONEYMAN ON GEOLOGY OF NEW BRUNSWICK. 



It will be evident by a glance at the Geological map of New 

 Brunswick, that the pre-carboniferous formations traverse the 

 country in approximate parallels, running N. E. and S. W. The 

 so-called central band of granite appears as one of those parallels, 

 traversing the whole of New Brunswick. Of this the granite of 

 the Nepisiguit is the N. Eastern extremity. Although there is 

 nothing intervening between the carboniferous and the granite on the 

 Nepisiguit, there is an intervention of another formation, between 

 the granite and the carboniferous to the west. In this fossils were- 

 found, but not sufficiently distinct for determination. On the north 

 side of the granite graptolites were found, but not in situ. It was 

 regarded as probable that they came from the strata that occupy 

 the position of the metamorphic slates of the copper mines, which 

 we have regarded as Lower Silurian. 



SOMERSET VALE TO D LHOUSIE. 



On our way we had to pass over the crystalline rocks of the 

 railroad cutting, north of the Tattagouche. At Petit Rocker, 

 about twenty miles distant, we saw a limekiln on the road side in 

 active operation. This led to inquiry after the position of lime- 

 stone. It was seen at a short distance crossing the road. Search 

 was made for fossils but we found none ; the limestone was dark in 

 colour. We passed over a considerable width of diorite and grits 

 before we reached Belledune. 



At Chambers' inn I found that the Rev. Mr. Fowler had kindly 

 told our host to send me to the shore. I here found a very inter- 

 esting series of rocks, replete with fossil-corals. I collected a large 

 and fine specimen of Halysites, Oatenulatus (chain-coral), fine 

 specimens of Pavosites, Gothlandica,? Stromatopera,? a large 

 branching coral, gen. and spec.(?), and a besLUtifulOyathophyllum. 

 The rocks were singular in colour and having trap interbedded. 

 There was no difficulty in determining their age. The Halysites 

 Oatenulatus indicates Niagara limestone (Upper Silurian). Prof. 

 Hall, in a paper read before the American Association, August, 

 1873, "On the relations of the Niagara and Lower TIelderburg
