the Middle Silurian to a base of strata of Lower Carboniferous 

 age. We thus take a greater leap upwards than was done down- 

 wai'ds on our entering upon the Barney's River Basin. The 

 difference is measured by our descent geologically in passing 

 through the Middle Silurian series. Proceeding onward we pass 

 from the Lower Carboniferous into a great Metamorphic series 

 which enters largely into the constitution of the mountains 

 through which passes the remarkably picturesque "Marshy Hope." 



Through this pass flows the eastern branch of Barney's River 

 and proceeds the line of Railway, in two sub-parallel lines. 



A beautiful section of a part of the metamorphic strata is 

 seen on the side of the railway. The latter proceeds onwards, 

 through the valley without any other rock exposures being ap- 

 parent. About a mile from the county line, strata A, (Middle 

 Silurian) are observed on the side of Barney's River. These ex- 

 tend onward into the County of Antigonish, and are cut by the 

 railway before it reaches the county line. We discontinue our 

 journey until I read notes on the map of Antigonish County. 

 General Sections. 

 On the map. 



Section line, No. 1. — This section commences on the Pictou and 

 Antigonish Co. line, 2 miles from Northumberland Strait and the 

 same distance from the N. west corner Arisaig Township, the 

 county line being the western boundary of the township. The 

 portion indicated is 3 miles distant from the top of the upper- 

 most member (D) of the typical " Upper Arisaig Series," situate 

 near the mouth of McAra's Brook in the county of Antigonish, 

 and on the Northumberland Strait. This line is zigzag, consist- 

 ing of three straight lines, which I shall designate respectively 

 1, 2, 3. 



Line 1. — Beginning at the starting point proceeds in a direc- 

 tion S. 25 W. to Sutherland's Mountain, Kenzieville, a distance 

 of 9 miles. In it course it traverses, 1st. The metamorphic rocks 

 of the Antigonish and Pictou Mountains. 2d. A carboniferous 

 band of rocks of the same mountains. 3d. A. B. & B'. of eastern 

 and middle branches of Barney's mountains, and ends at strata 

 with Diorite, of Sutherland's mountain at the west branch of
