placements of the strata, from the vicinity of Westport Village, 

 on the Rideau, in North Crosby, through Wolf Lake, in Bed- 

 ford, to Eagle and Long Lakes, in Hinchinbrooke ; thence 

 through Horse Shoe Lake, on the Salmon River, in Kennebec, 

 to and through Kahidar, Elzevir, Tudor and Lake townships, in 

 all a distance of 52 miles. This line of dislocation is accom 

 panied, in Bedford, Tudor and Lake, by numerous parallel 

 galena lodes; in Kaladar and Luke, by lodes carrying the sul- 

 phuret of copper, and in one instance, in the last named town- 

 ship, by a lode containing the sulphuret of bismuth in crystalline 

 masses of considerable size. The cupriferous lodes are invariably 

 bounded by diorites, green slates, and chloritic schists, or dolo- 

 mites, while both the galena and the bismuth are associated 

 with limestones. It is also noticeable that in the localities where 

 the lodes traverse the green slates and chloritic schists, the 

 copper ore is not confined to the lodes themselves, but extends 

 from them along the planes of bedding of both slates and schists, 

 forming bedded cupriferous zones, which can be traced for some 

 distance on the strike of the rocks. These zones, however, do 

 not appear to be of economic importance, nor is the copper ore 

 in the main lodes in sufficient quantity to be worthy of special 

 consideration. 



To the south of this first great dislocation, and about ten 

 miles distant from it, a second and similar important break was 

 made out, and traced for some distance in a parallel course, 

 northward of east, towards and through Frontenac County. This 

 runs from the south-eastern corner of Methuen township in Pe- 

 terboro' County, where its position is marked by Parker's Galena 

 mine, through Marmora, Madoc and Elzevir in Hastings County ; 

 thence through the village of Troy or Bridgewater to a position 

 on the Salmon River in Sheffield, about nine or ten miles to the 

 southward of where the first described fault crosses the same 

 river in Kennebec. In this position, the correctness of this line 

 of fault is verified by a fact recorded by Mr. Alexander Murray 

 in his Geological Report for 1852-53, in which he states as 

 follows : ' ' Six miles further down ( the Salmon River ) it 

 (a band of limestone) was seen below the exit of Long Lake, 

 where it is brought in by a dislocation indicated by a coarse 

 grained quartzo-feldspathic dyke, transverse to the stratification ; 

 the mica slate abutted against the dyke on the north-east, and 

 the limestone on the south-west."
