HONEYMAN — ON THE GEOLOGY OF NOVA SCOTIA. 35 



months. I thouglit I had met my Canadian acquaintance at Ari- 

 saig. The discovery of Eozoon, by Drs. Dawson and Hunt, in 

 specimens of the Arisaig ophiocalcite has confirmed this opinion. In 

 all probability this band of metamorphic rocks is overlaid unconform- 

 ably by lower carboniferous strata. Passing from Malignant Cove 

 along the road to Antigonishe we meet with a good outcrop of sand- 

 stones These lie to the east of the terminal ran^fe of the Arisais: moun- 

 tains, e.g. Sugar Loaf and McNeiPs mountains already referred to. A 

 continuation of these sandstones eastward will pass south of the Lau- 

 ren tian rocks, without giving much room for intervening rocks. 

 This region is forest. In this Laurentian series, it will be observed, 

 . there exists mica sufficient to account for the micaceous character of 

 the grits and sandstones already referred to. Many of the pebbles 

 of the conglomerates also noticed may have come from this quarter. 

 The only desideratum is a rock which could furnish the red granite 

 boulder of the mass of conglomerate found on the shore of St. 

 George's Bay. Although the rock has not been found, there is 

 every probability that it may be found there. Of this we are cer- 

 tain at least, that all the constituent minerals are there, although I 

 , have not found them united in the same rock, so as to form the rock 

 required. I go a step farther, and regard the syenite of McKeil's 

 mountain with the middle and upper silurian metamorphic overlying 

 it, and also the syenite with the overlying Leperditia limestone as 

 outcrops of the Laurentian series ; and then I would adopt Profes- 

 sor Hind's view of the character and age of the granite, and regard the 

 Sherbrook and Country Harbour rocks as outcrops of the same se- 

 ries, and consider that one process of metamorphism affected the 

 whole of this class of rocks in Nova Scotia. 



I find the following observation in Acadian Geology, Ed. 1855, 

 chap. 14, Devonian and Upper Silurian Systems, page 311, *^ Gra- 

 nite composed of distinct crystals of quartz, felspar and mica. 

 Granite is a rare rock in this district, though found in great masses 

 in the other metamorphoric districts. 



In my paper on the Geology of Londonderry Iron Mines, read 

 before this Institute in winter 1866-7, I noticed the existence of 

 granite among the rocks underlying the slates containing the iron 

 ores. These observations converge to the same point.
