HONEYMAN — GEOLOGY OF ANTIGONISHE COUNTY. 77 



the red and grey band of the Middle Arisaig series, and to regard 

 them and the rocks of the rest of our line of section which extends 

 to South River Lake, and Upper South River, consisting of 

 slates, diorites and quartzites, with cavities lined with large and 

 pellucid crystals of vitreous quartz, as having more resemblance to 

 the middle Arisaig series than to the metamorphic upper. The 

 absence of fossils and the isolation of these rocks, may, however, 

 render their relations and age doubtful. 



In the part of these around Poison's Lake, there is evidence of the 

 existence of iron and copper. Excavations have shown the exist- 

 ence of veins of hematite. Masses of micaceous oxide of iron are 

 scattered around^ and also oxide of iron with pyrite and calcho- 

 pyrite. The last have, at various times for a quarter of a century 

 excited interest, as indications of copper ore of economic value. 

 Two great searches had been made over twenty years ago. While 

 I resided in Antigonishe two others were made, and two or three 

 since that time. Considerable excitement was manifest in the 

 summer before last, when D. Donald Eraser of Springville in his 

 excavations, came upon a mass which seemed to be the desired lode. 



This excitement subsided when it was found that after all it was 

 only a mass ; it is likely however that the search will be resumed. 



Poison's Lake is on the border of Guysboro County. It and the 

 .South River Lake on our line of section, empty into South River 

 which flows through a long and fertile country and then enters into 

 Antigonishe Harbour, so that the waters of the district flow towards 

 the Atlantic on the south and the Gulf of St. Lawrence on the 

 north. 



Terminating our line of section — we have after the quartzite 

 with quartz crystals, Lower Carboniferous , unconformable, with 

 sandstone and limestone of St. Andrew's, we noticed the latter in 

 connection with the previous section. 



The Upper Palaeozoic part of the coast section as I have des- 

 cribed it seems to throw some light upon the character of the Lower 

 Palaeozoic or Eozoic ( ?).
