SOUTH COAST OF NEAV BRUNSWICK. 109 



occurs in Irregular beds and pockets in the conglomerate at Quaco, 

 and has probably been derived from veins of the mineral which occur 

 in the Lower Carboniferous rocks. 



Westward of Quaco the Trias occurs near Gardener's Creek, in a 

 patch about one mile and a half long and half a mile wide. The 

 character of the deposit is similar to that at Quaco, but the upper or 

 conglomerate member is wanting. 



Eastward of Quaco, but more than thirty miles distant, another small 

 area of Triassic sandstone has been recognised at Salisbury Cove. The 

 beds dip E.N.E., at an angle of 10°, and are of a paler red than at 

 Quaco. 



These remnants of New lied Sandstone on the New Brunswick side 

 of the Bay of Fundy concur, with the similar deposits in Nova Scotia, 

 in showing that the depression occupied by that bay had already 

 assumed nearly its present form ; and this, together with the fact that 

 the Carboniferous rocks had been disturbed and hardened before the 

 deposition of these later beds, affords, as Mr Matthew has well 

 remarked, strong evidence that the New Red Sandstones of the Bay of 

 Fundy are Triassic rather than Permian. 



5. General Remarks on the Trias of Nova Scotia and New 



Brunswick. 



It will be observed that, in the notes referring to the coast sections of 

 the New Red Sandstone, I have given especial attention to its relations 

 to the older rocks, especially those of the Carboniferous system. I 

 have done so, because much doubt formerly existed as to the precise 

 limits of this formation. The earlier writers on the geology of Nova 

 Scotia and New Brunswick associated it with the red sandstones and 

 gypsums of the Carboniferous period, and described the whole as " New 

 Red ; " and it was not until the first visit of Sir Charles Lyell that the 

 great beds of gypsum and limestone of Windsor, the Shubenacadie, 

 and other places, with their associated sandstones and marls, were 

 recognised as Lower Carboniferous. Even after Sir Charles had pub- 

 lished his results, these were dissented from both by Logan and 

 Gesncr, though both these geologists subsequently convinced them- 

 selves, and admitted that they had been in error ; and the latter even 

 went so far as to believe that the red sandstones of Bloinidon and 

 Cornwallis were also Carboniferous. It then became a question whether 

 there were really any rocks of the Triassic period in the province, and 

 to determine this point, the writer undertook, in 184G, a careful ex- 

 amination of the red sandstone and trap on both sides of the bay, the 

 results of which were published in the Proceedings of the Geological
