tain range. They are in general rather round-backed, but the outline is not 

 even, being interrupted by craggy eminences rather obtusely conical. It is 

 very probable that they are a part of the range upon which Hearne bestowed 

 the name of Stony Mountains. 



We encamped on the night of July 6th in lat. 66° 45' U", longitude 115° 42' 

 23", and forty-three miles W.b. N. of the Sandy River, at the foot of the most 

 rugged part of the range, where it is washed by the river. A high peak, which 

 was examined here, consisted of red granite and sienite, and some large beds 

 of greenstone were also observed ; but perhaps all these rocks are subordinate 

 to the clay -slate formation, that rock occurring in considerable quantity here, 

 having a greenish colour, and continuous pearly lustre. The rocks at this spot 

 appear to be primitive, but they are soon succeeded by others, which have 

 more the aspect of the transition class. Seven miles further down the river, 

 at the encampment of July 7th, the hills shewed less elevation and a more even 

 » outline, with less exposed rock. That which was observed consisted of a more 

 dull and earthy clay slate . 



Leaving this place on July 8th, we continued our course down the river, 

 which flowed for some miles between two ranges of hills, pretty even in their 

 outline, and round-backed, but with rather steep acclivities. The immediate 

 borders of the stream were either high banks of fine sand, or steep gravel cliffs ; 

 and sometimes in places where the hills receded to a little distance, the inter- 

 vening space was occupied by high sandy ridges, apparently the ancient banks 

 of the river. We now approached a range of hills which were visible from 

 yesterday's encampment, and which in form bore a considerable resemblance 

 to those in the neighbourhood of Point Lake, but having more the appearance 

 of a connected range. We had no opportunity of examining these hills, but 

 judging from the analogous forms of those at Point Lake, we infer that they 

 consist of clay slate* hornblendic gneiss, and granite, connected with rocks 

 of the transition series. The Copper- Mine River runs to the westward in a 

 tortuous course along the foot of this range, until it succeeds in effecting a pas- 

 sage through it in 116° 31' west longitude. At this place, according to Indian 

 account, the Bear Lake approaches nearest to the Copper-Mine River, the 

 breadth of the height of land between them not exceeding thirty or forty miles. 

 Below this spot, which is marked by the influx of a small stream, the river 

 assumes a northerly course, and becoming much narrower and more rapid,
