iferous limestone, lying on the middle silurian slate, and coalescing 

 with it, forming a breccia. Connected with this is a band of green 

 pyritiferous marble, which is exposed on the bank and in the bed of 

 the river, beside a bridge, and near the mouth of McDonald's Brook, 

 which enters from the opposite side. I shall have occasion to refer 

 to this brook again. 



Proceeding farther up the river, I found at Kennedy's, on a road 

 to Blanchard, a small outcrop of breccia, having limestone like a 

 paste, with angular pieces of metamorphic argillite. This outcrop 

 was about twenty paces in length, occupying an elevated position 

 in contact with the greenstone of anticlinal No 2. Starting from 

 the breccia and skirting the greenstone according to the course of 

 the river, we come to Squire McDonald's, and find above his house 

 the termination of the greenstone, and below his store, on the bank 

 of the river, an exposure of a band of lower carboniferous lime- 

 stone, which, above the bridge of Pleasant Valley, forms a wall on 

 the opposite side of the river, and re-crosses the river, v/here we 

 shall meet it again. 



Keturning to Blanchard, I find the bed of fossiliferous ore to be 

 of considerable thickness — forty feet or thereabout — and extendiu^^ 

 the length of McDonald's property, but not beyond it ; — a supposed 

 extension of it northward being an outcrop of reddish slate. 

 Passing over to the other side of axis No. 2, I found, beyond an 

 interval between the greenstone on the other side of Squire 

 Campbell's marsh, a fine outcrop of slate, with abundance of cri- 

 noids, and a Dalmania Sp? characteristic of the Clinton of Arisaig. 

 Proceeding onward to East River from this point, I found another 

 outcrop of similar slates. I saw several outcrops of slates, but did 

 not particularly examine them. They extend to a brook which enters 

 East River, near the bridge at Pleasant Yalley. They outcrop at the 

 mill dam and up the brook for some distance. I now come to 

 notice the relation that the band of limestone which I described as 

 forming a wall on the opposite side of the river, bears to the slates 

 that underlie it. The river separates this wall from the strata of 

 argillites which are finely exposed on the side of the river opposite 

 to it ; i. e. on the north side of the river. Proceeding along this 

 side of the river I pass five exposures of slate, and at last come to
