76 H0NEYMAN — GEOLOGY OF ANTIGONISHE COUNTY. 



Section 8. — Continued. 



This section from Arisaig Pier to the Mountains extending south- 

 west to the point where the Marshy Hope Road intersects the county 

 line between Antigonishe and Pictou Counties, passes through a 

 table-land which is covered by forest. On the north side of the 

 road at the county line there is a band of strata A of the Upper 

 Arisaig series with characteristic fossils. This outcrops on the side 

 of the road at the place indicated, and also on the road at the 

 coach stables, east. The section has an obscure passage — from 

 this south to the Ohio Mountains above Addington Forks. It 

 then traverses the red syenites which form the western boundary 

 of a considerable part of the southern carboniferous area of Antigo- 

 nishe. This syenite extends westward into the County of Pictou, 

 and southward into the County of Guysboro. At a distance of 

 about eight miles from Addington Forks — the section now running 

 eastward to Lochaber Lake, at right angles to its former course, 

 crosses the Ohio River, and passes to the Mountain west of Lochaber 

 Lake, with its granitoid diorite. Overlying this is a band of strata 

 A, Upper Arisaig, or (Middle Silurian), having abundance of 

 characteristic fossils. 



It is worthy of notice that this was the position where I first 

 discovered this member of the series in 1858. The fossils here are 

 generally casts, some of them are silicified. Perfect specimens 

 are occasionally found. Overlying this are strata of C and D, 

 Upper Arisaig (Upper Silurian), having also abundance of fossils. 

 On the side of the lake were found in situ, Chonetesi N. Scotica, 

 Crania acadiensis, Dalmania Logani and Clidophori, characteristic 

 of the upper part of D. Lochaber Lake in the line of section 

 lies beautifully between two parallel ranges of hills, its length 

 is 4 miles. The opening which is at the south end conveys its 

 waters to St. Mary's River, which empties into the Atlantic Ocean. 



The lake is about half a mile wide. Near the opposite side is 

 an islet, which is formed by tilted shales of red and grey colours. 

 This band of slates is of considerable length and breadth. They 

 form the elevated ridge on the east side of the lake. They are non- 

 fossil iferous. I am disposed to regard these as corresponding with
