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 dioritie conglomerate which I found at 
Wentworth, I. C. 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 Arvisaig series,” 
(Archean 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 6 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‘ south of Cooper’s and at Turner's 
with its Graptolithus clintonensis (priodon), Dalmanites, Lepto- 
coelia, 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
