HONEYMAN — ON THE GEOLOGY OF NOVA SCOTIA. 65 



aid's Brook, a small branch of East Eiver, where lower carbonifer- 

 ous sandstones outcrop. A continuation of these near Springville, 

 opposite the Bridge above Springville, shew a considerable area of 

 gypsum, with a continuation of funnels ; all to the S. of this is 

 lower carboniferous. 



The greenstone is homogeneous and ferruginous. It lies in the 

 axis of an anticlinal, which for convenience I shall designate anticlinal 

 No. 1. On the opposite side of this anticlinal, I found the lowest 

 strata highly metamorphic, and at the point of contact coalescing 

 with the greenstone. The Clinton slates above these are well ex- 

 posed in the Brook that passes immediately E. of the Presbyterian 

 Church. I did not find any fossils in these slates. The other 

 strata are covered by forest, until we get to Blanchard, in the vi- 

 cinity of the bed of fossiliferous iron ore, referred to in Dawson's 

 Acadian Geology, last ed., p. 591. In John McDonald's hill, I 

 found lower Helderberg strata with their characteristic fossils. 

 These appear to be the uppermost strata of this other side of the 

 anticlinal, and corresponding with the lower Helderberg of Spring- 

 ville, which I have already noticed. Situate in Blanchard, and 

 nearly opposite McDonald's hill, with its outcrop of fossiliferous 

 lower Helderberg strata, is the bed of fossiliferous iron ore referred 

 to. This evidently lies in Clinton slate, having a high dip. This 

 series forms a synclinal with the preceding series ; below the bed of 

 ore are strata which I conceive to be the equivalent of the Medina 

 sandstone. These are highly metamorphic, — the lines of stratifi- 

 cation being occasionally exhibited by weathering, and by beautiful 

 banded structure. 



Below these is an outcrop of homogeneous and ferruginous 

 greenstone. The preceding strata are finely exposed in a brook 

 which, issuing from Blanchard, enters East River. The exposure 

 forms a bold section, with a fine waterfall. The greenstone last 

 mentioned proceeds onward parallel with the exposure of strata, 

 and in the rear of it, widening as it proceeds, and ending in lofty 

 mountains, having their termination at East River. 



I would designate this greenstone as axis of anticlinal No. 2. 

 Near the point of contact of the slates and greenstone, where they 

 terminate near the river, is a considerable deposit of lower carbon-
