SIR: In all my official relations I have endeavored to be governed strictly by the instructions of my superior officers, and in reference to the alledged real or imaginary impropriety of my course towards Buffalo Hump in your letter of the 12th Oct. last, I must plead my instructions in mitigation which I followed strictly, not being in possession of any, except the verbal instructions of Commissioner Hubbard, which was in effect to exercise my best judgment in the management of the affairs of the Reserve, but in all things to be governed by strict rules of economy. In my report to you of the 12th Augst. I solicited written instructions, a copy of the Intercourse Laws and of the Contract for furnishing supplies for the Indians, but as yet, have not received even a reply to my communication. There is no Indian with whose character and habits I am more familiar than with Buffalo Humps; he is a fugitive from the Texas Agency of which I was placed in charge; the late Superintendent of that State worried with him for three years before he could induce him to settle, he would come in and make promises to do so, and the Superintendent would load him with presents, he would return to the prairies depredate upon the country until his blankets were worn out, then return with a plausible excuse for not coming in with his people, receive other presents return again to the prairies and repeat the same thing over again until the Superintendents patience became exhausted, and informed Buffalo Hump that he would not submit to any further trifling on the subject, that he had nothing more for him, but as he had come in peace, he might return in peace, but that afterwards he would pursue and hunt him down with the troops; Buffalo Hump then changed his tone, begged to be permitted to have a certain length of time allowed him to bring in his people without renumeration or presents, at that time it was granted, and at the appointed time he brought in his people and settled on the Reserve, where he remained until a feud took place between him and the Chief of the band located previously, which caused him to abandon the Reserve and pursue his former predatory habits. I induced him to come in this time, in addition to the other wild chiefs, who met Commissioner Pike in Augst. last, and entered into an informal treaty with them, it was the result of a years negotiation, which was carried on by means of messengers from this Reserve; it was attempted years ago by Judge Rollins, one of the ablest Indian Agents perhaps the U. S. ever had, who spent eighteen months in attempting to accomplish the object; Agent Stemm lost his life in efforts of the kind; Major Neighbors a very ingenious and competent Agent exerted his influence for six or seven years to no purpose:--Dr. Hill, a most popular Indian Agent and influential man, labored four years without effect, and Capt. Ross' influence was equally ineffectual, yet I am informed in your letter of the 12th Oct.
