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.

Suggestions with respect to the Indian tribes,

and the protection of our Trade.

IN the course of this work, a few general remarks have been hazarded respecting the Indian tribes of the prairies, and the dangers to be apprehended from them in future times to our trade beyond the Rocky Mountains and with the Spanish frontiers. Since writing those remarks, we have met with some excellent observations and suggestions, in manuscript, on the same subject, written by Captain Bonneville, of the United States army, who had lately returned from a long residence among the tribes of the Rocky Mountains. Captain B. approves highly of the plan recently adopted by the United States government for the organization of a regiment of dragoons for the protection of our western frontier, and the trade across the prairies. "No other species of military force," he observes, "is at all competent to cope with these restless and wandering hordes, who require to be opposed with swiftness quite as much as with strength; and the consciousness that a troop, uniting these qualifications, is always on the alert to avenge their outrages upon the settlers and traders, will go very far towards restraining them from the perpetration of those thefts and murders which they have heretofore committed with impunity, whenever stratagem or superiority of force has given them the advantage. Their interest already has done something towards their pacification with our countrymen. From the traders among them, they receive their supplies in the greatest abundance, and upon very equitable terms; and when it is remembered that a very considerable amount of property is yearly distributed among them by the government, as presents, it will readily be perceived that they are greatly dependent upon us for their most valued resources. If, superadded to this inducement, a frequent display of military power be made in their territories, there can be little doubt that the desired security and peace will be speedily afforded to our own people. But the idea of establishing a permanent amity and concord amongst the various east and west tribes themselves, seems to me, if not wholly impracticable, at least infinitely more difficult than many excellent philanthropists have hoped and believed. Those nations which have so lately emigrated from the midst of our settlements to live upon our western borders, and have made some progress in agriculture and the arts of civilization, have, in the property they have acquired, and the protection and aid extended to them, too many advantages to be induced readily to take up arms against us, particularly if they can be brought to the full conviction that their new homes will be permanent and undisturbed; and there is every reason and motive, in policy as well as humanity, for our ameliorating their condition by every means in our power. But the case is far different with regard to the Osages, the Kanzas, the Pawnees, and other roving hordes beyond the frontiers of the settlements. Wild and restless in their character and habits, they are by no means so susceptible of control or civilization; and they are urged by strong, and, to them, irresistible causes in their situation and necessities, to the daily perpetuation of violence and fraud. Their permanent subsistence, for example, is derived from the buffalo hunting grounds, which lie a great distance from their towns. Twice a year they are obliged to make long and dangerous expeditions, to procure the necessary provisions for themselves and their families. For this purpose horses are absolutely requisite, for their own comfort and safety, as well as for the transportation of their food, and their little stock of valuables; and without them they would be reduced, during a great portion of the year, to a state of abject misery and privation. They have no brood mares, nor any trade sufficiently valuable to supply their yearly losses, and endeavor to keep up their stock by stealing horses from the other tribes to the west and southwest. Our own people, and the tribes immediately upon our borders, may indeed be protected from their depredations; and the Kanzas, Osages, Pawnees, and others, may be induced to remain at peace among themselves, so long as they are permitted to pursue the old custom of levying upon the Camanches and other remote nations for their complement of steeds for the warriors, and pack-horses for their transportation to and from the hunting ground. But the instant they are forced to maintain a peaceful and inoffensive demeanor towards the tribes along the Mexican border, and find that every violation of their rights is followed by the avenging arm of our government, the result must be, that, reduced to a wretchedness and want which they can ill brook, and feeling the certainty of punishment for every attempt to ameliorate their condition in the only way they as yet comprehend, they will abandon their unfruitful territory and remove to the neighborhood of the Mexican lands, and there carry on a vigorous predatory warfare indiscriminately upon the Mexicans and our own people trading or travelling in that quarter.

"The Indians of the prairies are almost innumerable. Their superior horsemanship, which in my opinion, far exceeds that of any other people on the face of the earth, their daring bravery, their cunning and skill in the warfare of the wilderness, and the astonishing rapidity and secrecy with which they are accustomed to move in their martial expeditions, will always render them most dangerous and vexatious neighbors, when their necessities or their discontents may drive them to hostility with our frontiers. Their mode and principles of warfare will always protect them from final and irretrievable defeat, and secure their families from participating in any blow, however severe, which our retribution might deal out to them.

"The Camanches lay the Mexicans under contribution for horses and mules, which they are always engaged in stealing from them in incredible numbers; and from the Camanches, all the roving tribes of the far West, by a similar exertion of skill and daring, supply themselves in turn. It seems to me, therefore, under all these circumstances, that the apparent futility of any philanthropic schemes for the benefit of these nations, and a regard for our own protection, concur in recommending that we remain satisfied with maintaining peace upon our own immediate borders, and leave the Mexicans and the Camanches, and all the tribes hostile to these last, to settle their differences and difficulties in their own way.

"In order to give full security and protection to our trading parties circulating in all directions through the great prairies, I am under the impression that a few judicious measures on the part of the government, involving a very limited expense, would be sufficient. And, in attaining this end, which of itself has already become an object of public interest and import, another, of much greater consequence, might be brought about, namely, the securing to the States a most valuable and increasing trade, now carried on by caravans directly to Santa Fe.

"As to the first desideratum: the Indians can only be made to respect the lives and property of the American parties, by rendering them dependent upon us for their supplies; which alone can be done with complete effect by the establishment of a trading post, with resident traders, at some point which will unite a sufficient number of advantages to attract the several tribes to itself, in preference to their present places of resort for that purpose; for it is a well-known fact that the Indians will always protect their trader, and those in whom he is interested, so long as they derive benefits from him. The alternative presented to those at the north, by the residence of the agents of the Hudson's Bay Company amongst them, renders the condition of our people in that quarter less secure; but I think it will appear at once, upon the most cursory examination, that no such opposition further south could be maintained, so as to weaken the benefits of such an establishment as is here suggested.

"In considering this matter, the first question which presents itself is, where do these tribes now make their exchanges, and obtain their necessary supplies. They resort almost exclusively to the Mexicans, who, themselves, purchase from us whatever the Indians most seek for. In this point of view, therefore, coeteris paribus, it would be an easy matter for us to monopolize the whole traffic. All that is wanted is some location more convenient for the natives than that offered by the Mexicans, to give us the undisputed superiority; and the selection of such a point requires but a knowledge of the single fact, that these nations invariably winter upon the head waters of the Arkansas, and there prepare all their buffalo robes for trade. These robes are heavy, and, to the Indian, very difficult of transportation. Nothing but necessity induces them to travel any great distance with such inconvenient baggage. A post, therefore, established upon the head waters of the Arkansas, must infallibly secure an uncontested preference over that of the Mexicans; even at their prices and rates of barter. Then let the dragoons occasionally move about among these people in large parties, impressing them with the proper estimate of our power to protect and to punish, and at once we have complete and assured security for all citizens whose enterprise may lead them beyond the border, and an end to the outrages and depredations which now dog the footsteps of the traveller, in the prairies, and arrest and depress the most advantageous commerce. Such a post need not be stronger than fifty men; twenty-five to be employed as hunters, to supply the garrison, and the residue as a defense against any hostility. Situated here upon the good lands of the Arkansas, in the midst of abundance of timber, while it might be kept up at a most inconsiderable expense, such an establishment within ninety miles of Santa Fe or Taos would be more than justified by the other and more important advantages before alluded to, leaving the protection of the traders with the Indian tribes entirely out of the question.

"This great trade, carried on by caravans to Santa Fe, annually loads one hundred wagons with merchandise, which is bartered in the northern provinces or Mexico for cash and for beaver furs. The numerous articles excluded as contraband, and the exorbitant duties laid upon all those that are admitted by the Mexican government, present so many obstacles to commerce, that I am well persuaded, that if a post, such as is here suggested, should be established on the Arkansas, it would become the place of deposit, not only for the present trade, but for one infinitely more extended. Here the Mexicans might purchase their supplies, and might well afford to sell them at prices which would silence all competition from any other quarter.

"These two trades, with the Mexicans and the Indians, centring at this post, would give rise to a large village of traders and laborers, and would undoubtedly be hailed, by all that section of country, as a permanent and invaluable advantage. A few pack-horses would carry all the clothing and ammunition necessary for the post during the first year, and two light field-pieces would be all the artillery required for its defense. Afterwards, all the horses required for the use of the establishment might be purchased from the Mexicans at the low price of ten dollars each; and, at the same time, whatever animals might be needed to supply the losses among the dragoons traversing the neighborhood, could be readily procured. The Upper Missouri Indians can furnish horses, at very cheap rates, to any number of the same troops who might be detailed for the defense of the northern frontier; and, in other respects, a very limited outlay of money would suffice to maintain a post in that section of the country.

"From these considerations, and my own personal observations, I am, therefore, disposed to believe that two posts established by the government, one at the mouth of the Yellowstone River, and one on the Arkansas, would completely protect all our people in every section of the great wilderness of the West; while other advantages, at least with regard to one of them, confirm and urge the suggestion. A fort at the mouth of the Yellowstone, garrisoned by fifty men would be perfectly safe. The establishment might be constructed simply with a view to the stores, stables for the dragoons' horses, and quarters for the regular garrison; the rest being provided with sheds or lodges, erected in the vicinity, for their residence during the winter months."
