Conclusion of the Notice on " Gesner's Geological Surveys of 

 the province of New-Brunswick,^' and Jackson and Alger s 

 Geology of Nova Scotia'' — (From p. 301.) 



We have learnt in our former perusal of Gesner's Geolo- 

 gical Reports, that New-Brunswick presents a singular 

 aggregation of the older stratified rocks, and trappean and 

 other volcanic productions. These not only appear through- 

 out the interior of the district, but upon a general view, 

 they will be found to extend from the Scoodiac on the 

 American Boundary, in a north-easterly direction, along the 

 coast of the Bay of Fundy to the County of Westmoreland 5 

 " Presenting,^' as Mr. Gesner says, a vast basin, or trough, 

 which is occupied by the waters of the bay; and perhaps it 

 would not be speculating too far to assume, that the opposite 

 side of this basin, or trough, appears in Nova Scotia, where the 

 schistose rocks are seen sloping from a granite ridge, and 

 dipping towards the centre of this basin. 



Here again, we will remark, that the Greywacke and 

 slate rocks, not having been disturbed in their general di- 

 rection and inclination, have enabled Mr. Gesner to deter- 

 mine their relative positions, and he has, in consequence, 

 declared their identity with the Cambrian and Silurian sys- 

 tems of British geologists ; " Terms,^^ he adds, equally 

 applicable to an extensive class of rocks in New- Bruns- 

 wick.^^ 



By far the most interesting parts of the third report are 

 the several notices relating to the New Red Sandstone and 

 Coal formations of the County of Westmoreland, portions of 

 that to which had been noticed already in the second report. 

 That to which we now refer, the discovery of coal at Fre-
