kenzie river, (lat. 69°, long*. 130^), more than 

 twelve degrees west of the green-Stone moun- 

 tains *, known by the denomination of the 

 Copper Mountains, and visited recently by Cap- 

 tain Franklin. The colossal peak of Saint 

 Elia, and that of Mount Fairweather, of New 

 Norfolk, do not belong, properly speaking, to 

 the northern prolongation of the Cordilleras of 

 the Andes, but to a parallel chain (the mari- 

 time Alps of the north-west coast), stretching 

 towards the peninsula of California, and con- 

 nected by transversal ridges with a mountain- 

 ous land, between the 45° and 53° of latitude, 

 with the Andes of New Mexico (Rocky Moun- 

 tains). In South America (and my geognostic 

 table is particularly restricted to that part of 

 the New Continent), the mean breadth of the 

 Cordillera of the Andes is from 18 to 22 



135° : mouth of the Copper-mine river, according to Franklin, 

 115° 37'; according to Mackenzie and Hearne, 111°: mouth 

 of the Slave River, in the lake of that name, according to 

 Franklin, 112° 45' 5 according to Mackenzie, 113° west of 

 Greenwich). From these statements it results, 1st. that the 

 Rocky Mountains are in the parallel from 60° to 65°, at 124° 

 to 125° long, west of the meridian of Paris ; 2d. that the 

 northern extremity of the chain, west of the mouth of Mac- 

 kenzie river, is 130° 20' of long. 3 and, 3d. that the groupe 

 of the Copper-Mountains is 118° and 119° long., and 67° and 

 G8° latitude. Franklin's Journal to the Polar Sea, p. 638.
