NOVA SCOTIAN GEOLOGY. — HONEYMAN. 199 



tain side above, Mr. Goodfellow brought a piece of rock which 

 was found to be a conglomerate of peculiar character. It is al- 

 most identical with the dioritic conglomerates which I found at 

 Went worth, I. 0. R., with other conglomerates and rocks, which 

 led me to proper views of the age of rocks of the Arisaig moun- 

 tains, and to distinguish them from the "Lower Arisaig series," 

 (Archaean, Dana) and " Upper Arisaig series," (Middle and Upper 

 Silurian,) by making a "Middle Arisaig series" and correlating it 

 with Professor Ramsay's "Cader Idris" (Lower Silurian). The 

 distance from the north side of Bayley's Brook to the south side 

 McLean's is 5 miles. 



Other Mountains. 



My attention was also directed to the mountains on the south 

 side of the Marshy Hope railway. Opposite the Middle Silurian 

 (A) strata last examined, is a Brook (Bryan Daley's) which pene- 

 trates these mountains. Ascending this brook the first rocks 

 that I met with were apparently carboniferous strata consisting 

 of clayey shales and conglomerates. Succeeding these are ex- 

 posures of metamorphic slates — argillites. I shall have to 

 investigate these before I can arrive at any satisfactory conclu- 

 sion regarding their age. In the meantime I regard them as a con- 

 tinuation of whatever rocks may form the mountains at Mclver's, 

 and, therefore, as underlying the strata A, B of the Barney's 

 River Middle Silurian area. The same, doubtless extend farther 

 west behind Sutherland's Middle Silurian Mountain of our sec- 

 tion, so that they may be regarded as Pre-Middle Silurian and 

 therefore, Lower Silurian. 



Section line 1, division 2 extends from Sutherland's Mountain 

 to French River — a distance of 9 miles. Its course is N . 80 W. 

 It begins in the diorite of Sutherland's mountain, crosses A 

 strata of the mountains, passes through B strata with its Lin- 

 gula nodule bed, traverses B v south of Cooper's and at Turner's 

 with its Graptolithus clintonensis (priodon), Dalmanites Lepto- 

 ccelia, Strophomena, etc.. and ends at an igneous rock in French 

 River (a Lower Carboniferous rock). 



This Middle Silurian area is intersected diagonally by the line 

 of section. It is bounded on the north by the Carboniferous
