sent in my collection of fossils to the Museum of the Survey,, 

 Canada. 



Division (4.) 

 Archaean. 



I found and examined these rocks outcropping in all directions 

 along the road which leads to Blue Mountains. I have examined 

 them to a distance of two miles. These are separate 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 archsean rocks are felsites. In some places they have ap- 

 pearance of copper and micaceous iron ore. An outcrop of these 

 appears at McPhee's giving the series a width of 2.5 miles. 

 This may be the west side of the archcean 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, (JS T o. 3.) 



The rocks of this division contain the specular Iron ore at Mc- 

 Donald's on the south side of the river and S. of Blanchard's 

 This ore in 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 1868 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 

 metamoiphic strata. On emerging from the woods on my return 

 to the river, crystalline rocks were observed in a field on the 

 right. The ouctrop 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 forpalseonotological evidence 

 of age in the rocks themselves. I therefore searched for other
