worthy of examination. There is at Hard Ledge an exception- 

 ally well exposed syncline with its axis inclined* 15° towards 

 Shepady Mountain, and an unconformity with members of the 

 so-called Permian series. When in the neighborhood one 

 should not fail to see The Rocks of Demoiselle Cape below 

 Hopewell ; conglomerate clitFs, caved by the sea, and on a grand 

 scale carved into pinnacles and buttressed. 



Mill Cove, the base of Logan's measurements, lies opposite 

 Minudie, and between them, it is said, gypsum beds occur 

 agreeing with the horizon of the Pink Rocks of Maringouin. 



Section of the A^ova Scotia Coal Measures, as developed at the 

 Joggins, on th? Bay of Fandy, in descending order, from the 

 neighbourhood of the West Ragged Reef to Minudie, reduced to 

 vertical thickness.
