196 HONEYMAN— ON THE GEOLOGY OF NOVA SCOTIA. 



I found in them abundance of the EntoynostTaca^ Leperditia, and 

 Seyrichia. 



The examination of the metamorphic rocks of George's River, 

 led to a re-examination of those related at Arisaig : of this I now 

 give the results. This locality is unlike the other in this, that it is 

 well known. It has been the subject of papers which are to be 

 found in the Journal of the Geological Society and Silliman's 

 Journal, and it has been referred to in one of my papers read 

 before this Institute in 1870. 



This publicity is to be regarded as premature, for although it is 

 four years since I made the discovery of this series of rock, it was 

 only last summer that I had the opportunity of making such an ex- 

 amination of them as I regarded necessary for arriving at satisfac- 

 tory conclusions respecting their proper character, so that I am not 

 astonished that the conclusions formerly deduced are not altogether 

 so satisfactory as I could have wished. 



I have already given general descriptions derived from a cursory 

 examination made under very unfavourable circumstances. I now 

 give a very minute description resulting from a thorough examina- 

 tion made with an intelligent assistant, and under the most favour- 

 able conditions. The whole series is here beautifully exposed in a 

 fine shore section, so that on this consideration in addition to 

 priority and completeness, it is to be regarded as typical. Like the 

 George's River series, it has an easterly and westerly trend, so that 

 it is in a manner parallel to it. 



For the purpose of further comparison I shall commence at the 

 north end of the Arisaig series, as I did with that of Cape Breton. 



On the shore about miles from the north side of Cape George, 

 we have first syenites of three distinct colors, white, cream colored, 

 and red, with interbedded metamorphic quartzites of dark color. 

 These syenites are fine grained and have very little hornblende, 

 just enough to give them a syenitic character, and all contain crys- 

 tals of green feldspar. This is the only place where I have seen 

 these in the province. Its venation is also peculiar as far as my 

 experience shows. Besides being of quartz they are pervaded by 

 numerous veins of calcite ; some of these are from four to six inches 

 thick.
