You will therefore, so soon as Mr. Cowart shall report to you for duty, communicate to him the contents of this letter, and require him to investigate, as quietly as possible, the cases of all white persons found within the limits of his agency, and report to me, through you, such as are there without the authority of law, and such as may be unworthy longer to remain although they may have originally had permission to enter the country. Very respectfully, Your Obt, Sevt. A. B. GREENWOOD, Commissioner. Elias Rector, Esq.; Fort Smith, Arkansas. DEPARTMENT OF THE INTERIOR, OFFICE INDIAN AFFAIRS, June 4th 1860. SIR: The attention of this office has been called to an article which appeared in the Fort Smith Times (which is herewith enclosed) in which it will be seen that a secret organization has been formed in the Cherokee Nation, which is rapidly increasing. The existence of such an organization, the objects of which cannot be misunderstood, has caused in my mind the greatest apprehension as to the future peace and quiet of that country; and, if permitted to mature its plans, will be productive of the worst results. The article alluded to points to the Jones' as being the leaders in this movement, and who have been permitted for a long time to enjoy the privileges of that Nation. It is believed that the ultimate object of this organization is to interfere with the institutions of that people, and that its influences will extend to other tribes upon the Western border of Arkansas.
