It is an interesting fact that the Potawatomi of the west shore of Lake Michigan, notably those of Milwaukee, and probably those farther north, under the influence of Siggenauk or the Blackbird made a treaty at Cahokia, Illinois, with George Rogers Clark in September, 1778, and were thereafter for a time American allies. There was no actual service under Gen. George Washington, but the chiefs probably received medals or certificates in his name, and thus considered themselves fighting under his care. The Potawatomi returned to the British allegiance later, and opposed the Americans during all of the Indian wars. If our surmise of what Quitos means about Old Thunder is correct, it is a remarkable instance of the persistence of tradition concerning an American alliance, and a corroboration of Col. George Rogers Clark’s testimony about the attitude of the Milwaukee Potawatomi. Clark calls the two chiefs Saguina or “Mr. Black Bird and Nakiowin, two chiefs of the Bands of the sotairs [Chippewa] and Outaway Nation bordering on Lake Michigan and the River St. Joseph.” De Peyster, the British commandant at Mackinac, speaks in his poem or rhymed chronicle of 1779 of “Those runagates at Milwakie” and calls them in a footnote “A horrid set of refractory Indians.” Thus in the Revolution, while most of the Wisconsin Indians were strong British supporters, the mixed band of Chippewa, Ottawa, and Potawatomi west of Lake Michigan were American sympathizers. With regard to your second question: There is no record in the _Jesuit Relations_ of any visit of Allouez and Dablon to Milwaukee in 1670. Such a statement was made before Dr. Thwaites’s edition of the _Jesuit Relations_ appeared. Upon the publication in English of the exact text of the _Relations_ it was seen that Allouez visited the Kickapoo in 1670 (not accompanied by Dablon) at their village four leagues (about fifteen miles) from the Mascouten village which was near the site of the modern Berlin, on the upper Fox River. Thus it was impossible for the Kickapoo village to have been at Milwaukee. It is quite probable that Perrot and other traders may have been at Milwaukee and along the shore of Lake Michigan before Jolliet and Marquette, but there is no recorded voyage before theirs. THE INDIAN TRIBES OF IOWA Please send me the name and history of any or all the Indian tribes that at first occupied the state of Iowa. Also give me the name and history of any Indian tribe that once lived for a time, either long or short, in Iowa. DANIEL MCKENNA, _Charles City, Iowa_. The Indian tribes who are known to have dwelt in Iowa since historic times are the following: The Illinois were found there by Marquette and Jolliet in 1673, but returned to the east side of the Mississippi in a few years.
