Notes on the Ore Deposits of South Cheticamp, Cape 

 Bretow Island, N. S. — By M. Y. Grandin, Clieticamp. 



[Read 17th April. WOn.) 



One of the most interesting and instructive mining districts 

 ot' Nov^a Scotia, especially for the s^.udy of certain peculiar 

 structural features of ore deposits, is that of Cheticamp, 



PHYSICAL GFtOGRAPHY. 



The district lies in Inverness county, on the north-west side 

 of the Island of Cape Breton, about 110 miles north-east of 

 Pictou, from which place it may be reached by steamer during 

 the season of open navigation. During the winter, however, 

 the most direct route is by mail-coach from Inverness — the 

 terminus of the Inverness railway — a distance of about forty 

 miles. 



It comprises a tract of country about 13 miles in br-eadth, 

 extending along the Gulf of St. Lawrence in a north-easterl}^ 

 direction from Factory river to George's brook — a distance of 

 16 miles; its area being about 200 square miles. The most 

 trenchant and conspicuous natural division of the district is 

 into a narrow seaboard plain and a plateau lying to the east 

 and north-east of the plain. But for the purpose of this 

 description the great gorge of the Cheticamp river, which 

 traverses the district from south-east to north-west is taken as 

 the dividing line between North and South Cheticamp. The 

 principal metalliferous deposits are located in the southern 

 division which embraces almost the whole of the plain and 

 more than half the plateau area included within the district. 

 The barite and other deposits of the northern division have 

 been made the subject of investigation by Dr. H. S. Poole, so 

 they will not be described in this paper.*
