4. To ascertain the views of the Indians in the vicinity of Chicago, respecting the removal of the Six Nations to that district of country, an extract from the letter of Mr. Kenzie, sub-agent at Chicago, upon this subject, will show the situation in which this business stands. 5. To explain to the Indians the views of the Government respecting their intercourse with the British authorities at Malden, and distinctly to announce to them that their visits must be discontinued. It is probable that the annunciation of the new system which you have directed to be pursued upon this subject, and the explanations connected with it, can be made with more effect by me than by ordinary messengers. 6. To ascertain the state of the British fur trade within that part of our jurisdiction. Our information upon this subject is very limited, while its importance requires that it should be fully known. In addition to these objects, I think it very important to carry the flag of the United States into those remote regions, where it has never been borne by any person in a public station. The means by which I propose to accomplish this tour are simple and economical. All that will be required is an ordinary birch canoe, and permission to employ a competent number of Canadian boatmen. The whole expense will be confined within narrow limits, and no appropriation will be necessary to defray it. I only request permission to assign to this object a small part of the sum apportioned for Indian expenditures at this place, say from 1,000 to 1,500 dollars. If, however, the Government should think that a small display of force might be proper, an additional canoe, to be manned with active soldiers, and commanded by an intelligent officer, would not increase the expense, and would give greater effect to any representations which might be made to the Indians. An intelligent officer of engineers, to make a correct chart for the information of the Government, would add to the value of the expedition. I am not competent to speculate upon the natural history of the country through which we may pass. Should this object be deemed important, I request that some person acquainted with zoology, botany, and mineralogy may be sent to join me. It is almost useless to add that I do not expect any compensation for my own services, except the ordinary allowance for negotiating Indian treaties, should you think proper to direct any to be held, and intrust the charge of them to me. I request that you will communicate to me, as early as convenient, your determination upon this subject, as it will be necessary to prepare a canoe during the winter, to be ready to enter upon the tour as soon as the navigation of the Lakes is open, should you think proper to approve the plan. Very respectfully, &c. LEWIS CASS. Hon. JOHN C. CALHOUN, _Secretary of War_. II. DEPARTMENT OF WAR, January 14, 1820.
