Horizon of 

 Albert shales. 



1. Bed and grey conglomerates, Avith thin reddish shalos and beds of 

 gypsum, and flaggy, often bituminous, limestone. 



2. Eed and grey calcareous and argillaceotis beds in frequent alter- 

 nations, with thin conglomerates, and heavy beds of rubbly brownish- 

 red and fine-grained shales toAvards the top. 



3. Grey and red conglomerates of A r aried composition, with beds of 

 greyish and brownish oil-bearing micaceous and bituminous sandstones. 



4. Calcareous and bituminous shales, grey and dark brown, including 

 the so-called Albert shales, with an underlying set of greenish-grey 

 conglomerates. This series is overlaid unconformably by reddish or 

 brownish sandy shales, which form the basal beds of No. 3. 



Stratigraphically, the beds of Albert shales, or Division 4, as devel- 

 oped in Albert and Westmorland counties, may belong to a lower horizon 

 than the Carboniferous, and may constitute an upper portion of the 

 Devonian, but the prevailing fossils, both fishes and plants, seem to 

 indicate a Lower Carboniferous age. Bituminous shales, however, 

 are found to occur interstratified with undoubted Lower Carbonifer- 

 ous sandstones and conglomerates further west in Kings county, on 

 the South Branch of the Kennebecasis, as well as on the South-west 

 Branch of Trout Creek. On the latter stream the felsites of the moun- 

 tain are 0A 7 erlaid by red conglomerates and limestones, dipping north- 

 Avard at an angle of 20°. These, at the road crossing to Dutch 

 Valley, contain an interstratified band of highly bituminous shales of 

 the same type as those of the Albert Mines and Elgin, with numer- 

 ous scattered remains of the genus Palceoniscus. They are again 

 brought up by a fold about one mile doAvn the South-west Branch, and 

 are associated with the ordinary red sandstones and conglomerates 

 that mark the rocks of this age. Further doAvn on Ward's Creek, 

 about one and a quarter miles south of Sussex station, these 

 bituminous shales are again brought to the surface by another 

 undulation. Further west, about two miles below Norton station, 

 the extension of this anticlinal is seen on the post-road, where it 

 crosses the Moosehorn Brook. North of the railroad the bituminous 

 shales have not been met with, but on the road running west from 

 Butternut Bidge to Queensville, on Price's Brook, about five miles 

 west of the Bidge Corner, bituminous limestones similar to those of 

 Hillsboro' and the Albert Mines are seen, and would lead to the infer- 

 ence that the shales extend in a broad sheet across the intervening 

 country, brought up at intervals by the series of gentle undulations 

 which have affected the rocks of the central basin. In addition to the 

 localities already described, as well as those mentioned in the report of 

 1876-77, in Albert and Westmorland counties, shales of this character 

 are met with on the South Branch of the Kennebecasis, about six miles
