2. Another important object is, to procure the extinction of Indian titles to the land in the vicinity of the Straits of St. Mary's, Prairie du Chien, Green Bay, and upon the communication between the two latter places.
I will not trouble you with any observations respecting the necessity of procuring these cessions. They are the prominent points of the country—the avenues of communication by which alone it can be approached.
Two of them—Prairie du Chien and Green Bay—are occupied by a considerable population, and the Straits of St. Mary's by a few families. The undefined nature of their rights and duties, and the uncertain tenure by which they hold their lands, render it important that some step should be taken by the Government to relieve them. I think, too, that a cession of territory, with a view to immediate sale and settlement, would be highly important in the event of any difficulties with the Indians.
My experience at Indian treaties convinces me that reasonable cessions, upon proper terms, may at any time be procured. At the treaty recently concluded at Saginaw, the Indians were willing to cede the country in the vicinity of Michilimackinac, but I did not feel authorized to treat with them for it.
Upon this subject, I transmit extracts from the letters of Mr. Boyd and Colonel Bowyer, by which it will be seen that these gentlemen anticipate no difficulty in procuring these cessions.
3. Another important object is the examination of the body of copper in the vicinity of Lake Superior. As early as the year 1800, Mr. Tracy, then a senator from Connecticut, was dispatched to make a similar examination. He, however, proceeded no farther than Michilimackinac. Since then, several attempts have been made, which have proved abortive. The specimens of virgin copper which have been sent to the seat of Government have been procured by the Indians, or by the half-breeds, from a large mass, represented to weigh many tons, which has fallen from the brow of a hill.
I anticipate no difficulty in reaching the spot, and it may be highly important to the Government to divide this mass, and to transport it to the seaboard for naval purposes.
It is also important to examine the neighboring country, which is said to be rich in its mineral productions.
I should propose that the land in the vicinity of this river be purchased of the Indians. It could doubtless be done upon reasonable terms, and the United States could then cause a complete examination of it to be made.
Such a cession is not unimportant in another point of view. Some persons have already begun to indulge in speculations upon this subject. The place is remote, and the means of communicating with it are few. By timely presents to the Indians, illegal possessions might be gained, and much injury might be done, much time might elapse, and much difficulty be experienced, before such trespassers could be removed.
