CARBONIFEROUS AREA OF NEW BRUNSWICK. 



225 



1. Gray sandstone, often coarse and pebbly, with shales and conglo- 



merate, Hopewell Ferry, etc. These beds perhaps correspond to 

 the great sandstone ledges of Seaman's Quarries, Joggins. They 

 may be traced through Albert County to the south-west for a 

 considerable distance. 



2. Reddish sandstones and shales. 



3. Limestone and gypsum. 



4.. Red sandstone and conglomerate. 



0. Gray and dark-coloured conglomerate. 



G. Calcareo-bituminous shales of the Albert Mine, Hillsborough. 



These beds appear here to lie at the very base of the lower 



Carboniferous series. (See Section, Fig. 60.)

The Lower Carboniferous and Millstone-grit series of southern New 

 Brunswick thus appear to consist of the same elements as in the part 

 of Nova Scotia just described, with the exception of the occurrence 

 of a representative of the Lower Carboniferous Coal measures in the 

 bituminous shales of Hillsborough. In the vicinity of the Albert 

 Mine these seem to be the lowest member of the series ; but Professor 

 Bailey describes a lower conglomerate as underlying shales, similar to 

 those of Hillsborough, farther west at the Pollet River. In 1852, I 

 determined the geological age of the Albert deposits on stratigraphical 

 grounds, and since that time Mr C. F. Ilartt has added the confirmatory 

 evidence of fossils, having found specimens of Cyclopteris Acadica and 

 Lepidodendron cot^rugatuin, the characteristic plants of this portion 

 of the Carboniferous series, as seen in the cliffs at Horton Bluff in 

 Nova Scotia, to be described in the sequel. 



At the Albert Mine, the geologist stands at the extremity of a long 

 range of metamorphic (Devonian) rocks, stretching along the south 

 coast of New Brunswick, and terminating in Shepody Mountain. The 

 Lower Carboniferous rocks bend around the end of this ridge, and are 

 thrown off from its north-east and north-west sides. On the former 

 they extend in a belt of no great breadth to Salisbury Cove, beyond
