HONETMAN — ON THE GEOLOGY OF NOYA SCOTIA. 69 



Returning to the greenstone of axis No. 2, on the line of Simon 

 Fraser's mountain, we ascend to the summit, and find outcropping 

 the strata of the other side of the anticlinal. The numerous out- 

 crops shew that this band is of considerable width. These outrcops 

 also extend in a northerly direction, and run up against or to the 

 east of- Wier's mountain , — the most northerly outcrop being in 

 David McLean's brook. The distance between the two extremities 

 of this anticlinal being nine and a half miles. These strata are all 

 metamorphic, being apparently destitute of fossils. To the north 

 of the extremity of second anticlinal, lies the lower carboniferous, 

 having an outcrop of limestone. This is situate on the north side 

 of a little brook at the seat of a saw mill. The lower carboniferous 

 strata are not seen in contact with the underlying silurian strata. 

 The general direction of the two anticlinals that I have described, 

 is north-west. The next in order takes a different course. I have 

 said that the last outcrop of the eastern side of anticlinal No. 2, 

 lies to the west of Wier's mountain. This mountain is a great mass 

 of greenstone, being apparently bounded on the north by carbon- 

 iferous conglomerates, &c. The axial line of this mountain takes a 

 direction north east; while the axis No. 2 has a north west direc- 

 tion. On the south east side of the mountain, not far from Mr. 

 Wier's house, there is an outcrop of metamorphic silurian strata, 

 which are undoubtedly the Medina sandstone equivalent. These 

 have a north east strike ; they are continued onward in the same 

 direction, outcropping on the lower side of an old road, and then 

 they terminate at Sutherland's river, forming a somewhat im.posing 

 fall, which has been made the seat of a factory. Overlying these, un- 

 conformably , are lower carboniferous strata, conglomerates and grits : 

 these are well exposed in the river. The carboniferous formation 

 comes up against the lowest part of the silurian strata. We have 

 thus reached the extremity of the lower carboniferous of the Pictou 

 Coal Field. Returning to the silurian outcrop at Wier's, we pro- 

 ceed south east to Cameron's brook, where I found soft argillaceous 

 strata, like the Clinton of Arisaig, with abundance of characteristic 

 fossils ! These overlie the metamorphic of Wier's mountain. I 

 found no appearance of higher strata connected with those. Where 

 the brook enters Sutherland's river, in front of and above the falls,
