Mountain, which ia entirely composed of them, rises aboul 350 to iui> 

 feet bigh, for the most pari Laic and rocky, and extending along the 

 margin of the lake for nearly three miles. The fragments in the con- 

 glomerates in the last localities are chiefly of Laorentian rocks, and the 

 enclosed masses are often many tons in weight. In -..in.' parts, 

 without close examination, the conglomerate might be mistaken for 

 Laurentian gneiss. In many parts of this liill considerable exposures 

 of red Bhale are met with, as well as grey and chocolate-brown Band- 

 stones made op of fine grains of reddish feldspar and white quartz. 

 Althongb linos of deposition were observable in these sandstones, 

 I could tract.' no regular line of strike or dip." 



On the Little Perch River, which flows into Chabestachuan Hay, and 

 three miles from its mouth, Mr. McOual met with some small exposures 

 "t a reddish feldspathic rock, apparently of a brocciated character, 

 with calcareous -rain-, and Bhowing a considerable amount of a dull 

 green steatitic mineral. This rock occupies, as nearly as possible, the 

 position in which one mighl expect to meet with Mr. Richardson's 

 group, and may represent some of the conglomerates of that group. 

 Nothing was seen at all like the chloritio slates of Lakes Wakinichi 

 and Chibogomon. The above hand is not over one mile wide, coming 

 in between the Laurentian gneiss and the Cambrian limestone. 



Farther to the eastward, on the Temiscamie River, I tailed to find 

 any trace of these rocks, and am of the opinion that the belt due- nol 

 extend that far to the eastward. 



The following i- the description of the economic minerals found in 

 these rocks, as given by Mr. Richardson: — 



"Copper. — Copper pyrites ha- already been mentioned as occurring 

 in the neighborhood "t Paint Mountain, on Lake A-batagomaw. Ai a 

 point a little to the Bouth-wesl of the mountain, on the lake shore, this

 but no well-defined bed or vein was observed. The rock a green, 

 slightly calcareous, chloritic slate. These indications of copper, are 



seen \<>r nearly halfa mile north-easterly along the lake shore, to 



another point, where a bed or vein, two feet thick, containing copper- 

 pyrites, i- -ecu in chloritic rock for ahout twenty feet Its strike

 percent. For about three-quarters of a mile farther along the shore, 

 -pecks of the yellow sulphuret and the green carbonate of copper 

 are met with wherever the rook appears, At the end of this distance, 

 and just under Paint Mountain, the rock i- Largely charged with
