NOVA SCOTIAN GEOLOGY.—HONEYMAN. 197 
We proceeded onward to Mr. Melver’s at the back of Cameron’s 
mountain, no outcrops appeared. We then descended Mclver’s 
Brook proceeding northward, no strata were seen for a consider- 
able distance, at length strata appeared in great mass, which 
were found to be our Silurian (A) strata succeeded by B, crossing 
the brook to proceed westward as mountain strata, including 
Sutherland’s mountain of our section. Their boldness, and hard- 
ness of A, have constituted them mountain rocks. Sutherland’s 
mountain strata are tilted ; fossils abound in them, such as Arisaig, 
and quartz veins are also abundant. 
A great proportion of the mountain consists of Diorite. - It is 
well exposed on the back of the mountain reaching nearly to its 
summit. This is the usual association in Nova Scotia, east and 
west. In Antigonish, Pictou, Annapolis and Digby counties, 
strata A of the upper Arisaig series are invariably associated 
with intrusive Diorite. Succeeding this band are B. & B’. strata, 
these contrast strikingly with the preceding. They are generally 
very soft furnishing the pencil stone of How's Mineralogy of 
Nova Scotia, when exposed they become clay. The lower strata 
contains my “ Lingula nodule bed.” As usual at my last visit I ex- 
tricated a great number of nodules from its two exposures 
These contain beautiful lingulew of several species. B strata as 
usual furnish a great variety of genera and species peculiar to 
our Clinton period. They will be found included in our lists of 
fossils in the sequel. The west branch of Barney’s River is the 
approximate boundary of this Middle Silurian area. The Car- 
boniferous begins in the river at the mill north of McPhee’s 
Silurian (A) strata. At Dewar’s Furniture Factory strata B ex- 
tended beyond the river. Between Robertson’s and the Rev. Mr. 
McKeehan’s, the carboniferous mountains south of Piedmont 
Valley, have their extremity on the east. This apparent intrusion 
into the Middle Silurian originally led me to infer a connection 
with Cameron’s mountain already referred to. 
ANTIGONISH AND Pictou MOUNTAINS. 
From McPhee’s extremity of A (Middle Silurian strata) I cross- 
ed the Middle Silurian and then the Carboniferous, and reach- 
ed the old mountain road at Bailey’s Brook. At the bridge and
