1853.] DAWSON ON THE ALBERT MINE. 109 



at Minudie, Napan River, and other places, and extending eastwardly 

 to Pugwash, and, as I am informed, westwardly to Cape Merangouin. 

 Proceeding to the N.W., however, we do not continue to find a de- 

 scending series ; but, on the contrary, passing over an antichnal Hne, 

 we find at Fort Cumberland and other places in New Brunswick, a 

 repetition of the carboniferous rocks with northerly dips. The 

 highest beds seen on this line of section appear at the Ferry, east side 

 of Petitcodiac River ; these are grey sandstones with Calamites, Ar- 

 tesia, and trunks of Coniferous trees, probably belonging to the lower 

 part of the coal-measures. At Dorchester, and near Bennett's ship- 

 yard, on the west side of the Petitcodiac, the same beds are repeated 

 with southerly dips (S.S.E. to S.E.), and thence to the Albert Mine, 

 distant about ten miles. "We have, as far as the nature of the ground 

 will allow us to ascertain, a descending series, apparently as follows : 



Grey sandstone, often coarse and pebbly, with shales and con- 

 glomerate ; 

 Reddish sandstone ; 

 Limestone and gypsum ; 

 Red sandstone and conglomerate ; 

 Grey and dark conglomerate ; 

 Calcareo-bituminous shales of Albert Mine. 



In the vicinity of the beds last mentioned are the metamorphic 

 schistose rocks of Shepody Mountain, which I had an opportunity of 

 examining in 1849 ; these are probably older than the Carboniferous 

 system, and underlie the Albert shales, which seem to occupy the 

 centre of an anticlinal running out from the metamorphic rocks into 

 a carboniferous country. The order of superposition sketched above 

 I have endeavoured to represent in fig. 1, which differs from a section

 and Albert Mine.

which I have seen in an anonymous pamphlet on the Albert contro- 

 versy, principally in shovidng the anticlinal intervening between the 

 Petitcodiac River and the South Joggins. 



In the position above indicated as that of the Albert shales, and 

 especially in the vicinity of the older formations, we should expect 

 to find in Nova Scotia a group of rocks corresponding to them in 

 lithological character, (except that the Albert shales are more highly 

 bituminous than any yet known in that country) . On the other hand, 

 no group of shales in the higher members of the Carboniferous system
