the date 1629 is the last one in which Champlain could have obtained his information for his map published in 1632, since he was deported by English conquerors from his colony in the former year, and did not return until 1633. Next to Brulé must be placed Jean Nicolet, who visited the Sault in 1634; whether he ascended the strait to the lake itself is conjectural. Then in 1641 came the great gathering of Indians attended by the Jesuit fathers, Jogues and Raymbault. (See L. P. Kellogg’s _Early Narratives of the Northwest_, New York, 1917, 19-25). The first description of Lake Superior is given by Pierre Esprit Radisson in his _Journal_. The probable date of his voyage thereon is 1661, but Father René Ménard arrived at Keweenaw Bay in the autumn of 1660. It appears probable that the date of the discovery of Lake Superior cannot be determined with accuracy, and must remain uncertain unless scholars accept the conclusions of Butterfield and Sulte concerning Brulé. The same is true of the discovery of the upper Mississippi; it has been claimed for Nicolet in 1634, for Radisson in 1659, for La Salle in 1669, all antedating the voyage of Jolliet and Marquette in 1673. The truth is that from the beginning of French settlement on the St. Lawrence there was much roving to the sources of the great river. Many of these coureurs des bois were brave and courageous explorers, but they kept no records. It is thus dogmatic to say that the visit of the first white man to any given point occurred on such or such a date. We can only say when the first records were made describing such an event. The records for the voyage of Brulé and Grenolle in 1622 have not yet been universally accepted. THE POTAWATOMI DURING THE REVOLUTION: FATHER ALLOUEZ AMONG THE KICKAPOO I am sending you some more letters from Quitos. In one of these letters he refers to War Chief Thunder fighting with George Washington against the Canadians. I would like to find out what fight that was. Can you tell me? I would also like to find out whether Fathers Dablon and Claude Allouez visited the Kickapoo Indians on Milwaukee River in 1670 a few years before Jolliet and Marquette discovered the Mississippi. I have seen something to this effect somewhere. A. GEREND, _Cato, Wisconsin_.
