They recede with the aborigines, before the tide of civilization;but a diminished supply will remain in the mountains and uncultivated tracts of this and other countries, if the avidity of the hunter can be restrained within proper limitations.
* An animal called the stoat, a kind of ermine, is said to be found in North America, but very inferior to the European and Asiatic.
* * The finest fur and the darkest color are most esteemed; and whether the difference arises from the age of the animal, or from some peculiarity of location, is not known. They do not vary more from the common marten than the Arabian horse from the shaggy Canadian.
Height of the Rocky Mountains.
VARIOUS estimates have been made of the height of the Rocky Mountains, but it is doubtful whether any have, as yet, done justice to their real altitude, which promises to place them only second to the highest mountains of the known world. Their height has been diminished to the eye by the great elevation of the plains from which they rise. They consist, according to Long, of ridges, knobs, and peaks, variously disposed. The more elevated parts are covered with perpetual snows, which contribute to give them a luminous, and, at a great distance, even a brilliant appearance; whence they derive, among some of the first discoverers, the name of the Shining Mountains.
James's Peak has generally been cited as the highest of the chain; and its elevation above the common level has been ascertained, by a trigonometrical measurement, to be about eight thousand five hundred feet. Mr. Long, however, judged, from the position of the snow near the summits of other peaks and ridges at no great distance from it, that they were much higher. Having heard Professor Renwick, of New York, express an opinion of the altitude of these mountains far beyond what had usually been ascribed to them, we applied to him for the authority on which he grounded his observation, and here subjoin his reply:
Columbia College, New York, February 23, 1836.
Dear Sir, - In compliance with your request, I have to communicate some facts in relation to the heights of the Rocky Mountains, and the sources whence I obtained the information.
In conversation with Simon M'Gillivray, Esq., a partner of the Northwest Company, he stated to me his impression, that the mountains in the vicinity of the route pursued by the traders of that company were nearly as high as the Himalayas. He had himself crossed by this route, seen the snowy summits of the peaks, and experienced a degree of cold which required a spirit thermometer to indicate it. His authority for the estimate of the heights was a gentleman who had been employed for several years as surveyor of that company. This conversation occurred about sixteen years since.
A year or two afterwards, I had the pleasure of dining, at Major Delafield's with Mr. Thompson, the gentleman referred to by Mr.
M'Gillivray. I inquired of him in relation to the circumstances mentioned by Mr. M'Gillivray, and he stated that, by the joint means of the barometric and trigonometric measurement, he had ascertained the height of one of the peaks to be about twenty-five thousand feet, and there were others of nearly the same height in the vicinity.
I am, dear sir, To W. Irving, Esq.
Yours truly, JAMES RENWICK.
