206 NOVA SCOTIAN GEOLOGY.—HONEYMAN.

Canada. 
DIvIsIon (4.) 
Archean. 
I found and examined these rocks outcropping in all directions 
along the road which leads to Blue Mountain. I have examined 
them to a distance of two miles. These are separated from the 
river by a band of Middle and Upper Silurian? strata, which 
borders on the north side of the river, and comes into contact 
with a considerable bed of Lower Carboniferous Limestone. 
The archzean rocks are felsites. In some places they have ap- 
pearance of copper and micaceous iron ore. An outerop of these 
appears at McPhee’s giving the series a width of 2.5 miles. 
This may be the west side of the archwan of the Keppoch and 
Ohio, Antigonish County. I have not had an opportunity of 
tracing a connection between the two areas of crystalline rocks. 
Division 5. 
Iron Ore, (No. 3. 
The rocks of this division contain the specular Iron ore at Me- 
Donald’s on the south side of the river and S. of Blanchard’s. 
This ore 17 situ was first shown to me by Mr. Donald Fraser in 
1861, when I collected specimens of the various ores of the dis- 
trict for the London Exhibition of 1862. It seemed to indicate a 
deposit of economic importance, subsequently in 1869 when I 
investigated its geology the outcrop was obscured by an enormous 
pile of stones on its top, and it was with difficulty that I secured 
a passable specimen of the ore for our Museum collection. I ex- 
amined the containing strata and found them to be dark coloured 
“metamorphic strata. On emerging from the woods on my return 
to the river, crystalline rocks were observed in a field on the 
right. The outcrop of these is of considerable extent. The rocks 
are igneous and intrusive, like other rocks of the section on the 
north side of the river. We had thus the appearance of a mono- 
clinal, the dip being southerly and the strike east and west. 
The extreme metamorphism of the rocks and the general aspect 
gave no encouragement for the search for palxeontological evidence 
of age in the rocks themselves. I therefore searched for other
