62 HOXEYMAN GEOLOGY OF ANT1GONISHE COUNTY. 



sections is at the mouth of Smith's Brook, being the first rocks 

 of the section No. 9. Here by a. fault they are thrown forward 

 upon the shore ; another set of strata coming in between them and 

 the lofty bank of drift on the south. 



Large boulders of amygdaloid are seen on the shore at this point. 

 These seem to indicate the existence of a continuation of the trap 

 dyke, covered by the sea. 



The character of the strata now reached differs very much from 

 the preceding. 



On palasontological considerations, I have separated them from 

 the others. This conclusion has been confirmed by the analogy of 

 the Upper Arisaig series of Springville, East River of Picton. 

 Peculiar organisms, found nowhere else, are common in the same 

 position to both. [Collections in the Provincial Museum, and

 Street, Montreal. .] 



Being palasontologically and lilhologically different, I regard the 

 strata in the section as the beginning of C, Aymestry limestone. 

 These strata are black, coarse, hard slates and shales. The one is 

 so hard that it is scarcely possible to extract fossils from them — the 

 others are so yielding that it is almost equally impossible to pre- 

 serve the fossils taken out of them. 



These rocks extend along the shore in ledges as far as McAdanrs 

 Brook. They have a southerly dip. Succeeding them in the sec- 

 tion are shaly strata, also of dark colour, having numerous and 

 large concretions, regularly rounded. Beautiful fossils abound in 

 them, but they cannot be extracted, as the concretions are very 

 hard, besides they have a cross fracture. 



After these come the ledges of Moydart Point. Those consist 

 of compact argillaceous strata with shales. They are very fossil- 

 iferous ; the fossils being highly characteristic of C. 



Extending alonjj the shore to some distance south west of this 

 point, and strongly resisting the elements by their hardness, they 

 form bold ledges, precipices and deep recesses. They pass into 

 D, Upper Ludlow. These strata present the same general aspect 

 as the preceding. Only the highest strata become beautifully
