HONEYMAN — ON THE GEOLOGY OF NOVA SCOTIA. 37 



mens is flesh coloured ; the quartz glassy white and red ; the mica 

 black and white. Some of the plates of black mica are 1 x J inch ; 

 others IJ x 1 inch. The inland specimen of granite is the exact 

 counterpart of the specimen from the mass of conglomerate in St. 

 George's Bay : this is a coincidence. Comparing a specimen of 

 the red syenite of the Laurentian at Arisaig, with a specimen of the 

 red syenite of the syenite and limestone mountain S. of Antigonishe 

 harbour, I find that the latter is much more homblendic than the 

 former. I find in the specimen of the Antigonishe harbour syenite 

 a plate of green mica, the same as the mica of the specimen of gra- 

 nite from the Big Baddeck mountain. Mr. Hendry has kindly 

 located Wagamatcook Gold Field and the St Ann's serpentine on 

 a map of Cape Breton, belonging to the Crown Land oflioe. This 

 map is on a scale of 2 J miles to the inch. Upon the same map, 

 Mr. Murray and Mr. Austin, of the Crown Land department, have 

 located for me the rocks in the district of Aspy Bay, which pro- 

 duced the specimen of granite. On drawing a straight line on this 

 map from Baddeck mountain so as to bisect the line connecting 

 Whitehead with the locality having the granite, seventeen and a 

 half miles S. of W. from it — of course this is only to be consider- 

 ed an arbitrary line — I find that Wagamatcook auriferous slates is 

 ^ve miles from the line on the one side, and St. Ann Laurentian 

 three miles from the same line on the other side. These facts are 

 somewhat striking, and may indicate Cape Breton as the meeting 

 place of undoubted Laurentian and auriferous silurian, and as 

 connecting Arisaig Laurentian with the granites of the Nova Scotian 

 Gold Field- 

 In this way we come to the conclusion at which Professor Hind 

 had arrived, by a shorter process, in reference to the Geological age 

 of the gneissoid rocks of JSTova Scotia and Cape Breton. 



It will be observed that there are certain great geological 

 formations that lie between the Laurentian and Middle Silurian 

 which have no representative at Arisaig or the other localities which 

 it represents, viz., the Huronian or Cambrian, and the Lower 

 Silurian. Dr. Dawson in his Acadian Geology, 1st Ed. pointed 

 out the band of rocks on the Atlantic coast which are the gold bear- 

 ing rocks as Lower Silurian^ I imitated his example in maintaining
