"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.
