58 H0XEYMAX GEOLOGY OF ANTIGOXISHE COUNTY. 



of McAra's Brook, we find fin outcrop of slates in a little brook. 

 This brook proceeds through a hollow which seems to be a short 

 way to Moydart. 



We now descend into the bed of the brook and make it our 

 pathway as there is none other to be found. Coming into the 

 line of the mountains of our sections we see lofty exposures of 

 rocks. They are sections of the putrosilex band. Descending the 

 brook the lofty mountains rise on either side without showing out- 

 crops of rocks. We find that the path instead of being a compara- 

 tively straight and short one is tortuous and long, as the brook 

 makes considerably west of south. We are diverted from our path 

 as Bruin is seen to lie in our way ; we climb and pass him by on 

 the steep mountain side. After some time we descend and reach a 

 saw mill on the side of the road. To the left the mountain rises, 

 an outcrop of slates is seen and examined. We proceed. 



Coming to the side of the advanced mountain we see an outcrop 

 of rock towards its summit. We climb and find the outcropping 

 rocks to be slates, but not red slates. The Lower Carboniferous 

 Formation succeeds, having a brine spring on the roadside, a com- 

 mon occurrence in this geological horizon in Nova Scotia. 



We are now on the west of the upper Arisaig series. The east- 

 ern branch of Knoydart Brook here unites with the branch which 

 we have just traversed. We are again in Bruiiis Highway, and 

 near the Pictou County line. A range of lower carboniferous 

 mountains and level ground now take the place of the upper Arisaig 

 rocks. These mountains on the north and the continuation of 

 Arisaig mountains on the south bound a beautiful and fertile valley, 

 which is hid from the traveller who passes along the shore road. 



Section 12. — The Coast from Morristown Township to the 

 mouth of Knoydart Brook. 



Beginning at the line of Morristown and Arisaig Townships, i.e. 



about miles from the north side of Cape Sc. George, we find 



exposed on the shore mctamorphic slates of dark colour. These 

 slates escaped observation until 1871. I was equally astonished 

 when I found them, as I had been in 1868, when I. discovered those
