part of the section. Boulders from the bed, lying on the shore had 

 long attracted attention and excited enquiry in reference to their 

 origin. Proceeding, limestone occurs having bold sections, and 

 then we have projecting into the sea lofty cliffs of hard and soft 

 gypsum and beds of clays, with fibrous gypsum, and red in great 

 variety. 



The intimate connection manifest between the carbonate and 

 sulphate of lime when the two occur in contact, seems to me at 

 variance with some theories that have been advanced relating to the 

 origin of gypsum. We have now come to the mouth of Antigo- 

 nishe harbour. Monk's Head beyond the harbour at a distance of 



miles from Ogden's, shows a continuation of the gypsum 



deposits. Here there is a section of gypsum, which seems to be 

 the southern limit of these deposits. These limestones with gyp- 

 sum, are also of great longitudinal extent. 



At Ogden's Point they are seen leaving the shore. Their 

 course indicated by a series of elevations of 50 feet on Bayfield 

 Plan of the harbour, run parallel with the mountains described, and 

 show occasionally conglomerate underlying, until we reach Xorth 

 River — the line between Morristown and Dorchester Township. 

 On this river the gypsum is prominent and well exposed. It rises 

 in hills and is also exposed in the river and road sections. It 

 reaches to the mouth of the river and is exposed on the opposite 

 side of the harbour in bold sections. It is not again seen on the 

 north side of the harbour, as it has passed over to the south, appear- 

 ing on that side of the harbour, extending southward on South 

 River, and crossing the road from Antigonishe to the Strait of Canso. 

 On the south side of the harbour it is associated with syenite and 

 fossiliferous limestone. Sometimes the syenite apparently stands 

 alone — at other times it is in direct contact with the fossiliferous 

 limestone — one instance is notably so. AVe have an elevation 

 which rises 300 feet above the sea level. I have elsewhere referred 

 to this case as subversive of the theory advanced by some geologists 

 — maintaining that the marbles of Cape Breton are lower car- 

 honiferous limestones, metamorphosed by the action of syenite.
