“Sir: Since writing the letter to you of the 5th instant, Gov. Cass has arrived here, and submitted to the Secretary of War his views, as to the propriety of directing you to proceed into Lake Superior and the Mississippi country, &c. These views have been approved, and I am accordingly directed to instruct you to proceed as soon as your arrangements can be made for the purpose, on the proposed expedition. The objects to be accomplished are so well known, and have also been so fully explained in the letter of Gov. Cass to you of the 9th of August last, that it is deemed unnecessary to give you any further instructions on the subject. “Orders will be issued through the proper department, to the Commanding Officer at the Sault Ste. Marie for a detachment of the troops, to form a part of the proposed expedition. “Very respectfully, &c. SAMUEL S. HAMILTON.” “DEPARTMENT OF WAR, } _Office of Indian Affairs, May 3rd, 1832_. } “Sir: Your letter of Feb. 13th has been received, and its general views are approved. The Secretary of War deems it important that you should proceed to the country upon the heads of the Mississippi, and visit as many of the Indians in that, and the intermediate region, as circumstances will permit. “Reports have reached the department, from various quarters, that the Indians upon our frontiers are in an unquiet state, and that there is a prospect of extensive hostilities among themselves. It is no less the dictate of humanity, than of policy, to repress this feeling, and to establish permanent peace among these tribes. It is also important to inspect the condition of the trade in that remote country, and the conduct of the traders. To ascertain whether the regulations and the laws are complied with, and to suggest such alterations as may be required. And finally to inquire into the numbers, standing, disposition and prospects of the Indians, and to report all the statistical facts you can procure and which will be useful to the government in its operations, or to the community in the investigation of these subjects. “In addition to these objects, you will direct your attention to the vaccination of the Indians. An act for that purpose, has passed Congress, and you are authorised to take a surgeon with you. Vaccine matter prepared and put up by the Surgeon General is herewith transmitted to you, and you will, upon your whole route, explain to the Indians the advantages of vaccination, and endeavor to persuade them to submit to the process. You will keep and report an account of the number, ages, sex, tribe, and local situation of the Indians who may be vaccinated, and also of the prevalence, from time to time, of the small pox among them, and of its effects as far as these can be ascertained.
