Note 25 — INTRODUCTION.

(25) A few extracts concerning them will be interesting. “The chain of the Rocky Mountains, after being considerably depressed in latitude 46° and 48°, attains a much higher elevation from latitude 48° to 49°, and, continuing in a westerly direction, it separates the affluents of the Saskatchewan and MʻKenkie from those of Columbia or Oregon and other rivers which flow into the Pacific. These mountains appear to decrease again from about 58° to 62° northern latitude, where probably they do not exceed 4000 feet in height; and, still further north, are estimated at less than 2000 feet, between the latitudes of 42° and 58° north. Several peaks rise far above the snow line.
