leased the land to Barnes for his picnic grounds. THE DISCOVERY OF LAKE SUPERIOR In Volume Seven of the _American Nation_ Mr. Thwaites states (page 52) that Lake Superior was discovered in 1616. All other secondary accounts give 1629. Can you tell me whether or not the date 1616 is a misprint? If not where can I get the information about its discovery? E. G. DOUDNA, _Eau Claire, Wisconsin_. The dates of the discoveries of the several great lakes are not definitely known, and there is no uniformity of statement concerning their first exploration. Dr. Thwaites’s works reflect this uncertainty. In the _American Nation_ volume to which you refer he was inclined to accept the theory of Etienne Brulé’s exploration of Lake Superior, and thought it might have occurred after his journey to the Susquehanna in 1615, and before his return in 1618 to Quebec. Therefore he gives the date as 1616. In his _Wisconsin_, published in 1908, he appears to have rejected the theory of Brulé’s explorations, and states that Jean Nicolet in 1634 was probably the discoverer of Lake Superior. In his school _History of the United States_ (Boston, 1912) he shows his doubt by giving “about 1629” as the date of the discovery. Not all secondary accounts give the date as 1629. Our own opinion is that there is no authority for this date, and that it arises from a misinterpretation of Edward J. Neill’s statement in Justin Winsor’s _Narrative and Critical History of America_, IV, 165. One of the latest histories of the Great Lakes (Channing and Lansing’s _The Story of the Great Lakes_, New York, 1909) gives no date for the discovery of Lake Superior, but assigns 1610 to the first white man’s voyage on Lake Huron, five years earlier than the traditional one of 1615 for Champlain’s first voyage. The whole matter turns on the career of Etienne Brulé, one of the youths selected by Champlain to reside among the Indians and learn their language. His adventures were first discussed in detail in C. W. Butterfield’s, _Brulé’s Explorations and Discoveries_ (Cleveland, 1898). A more recent discussion in French, by the eminent Canadian authority Benjamin Sulte, appeared in the Canadian Royal Society _Proceedings and Transactions_, 3d series, vol. 1, section 1, 97-125. Butterfield and Sulte substantially agree, and both consider that Etienne Brulé with a companion named Grenolle probably visited Lake Superior and explored it in 1622-23. The evidence is somewhat circumstantial, and the point may never be determined; but Champlain must have had some information, aside from that furnished by the Indians, for upon his map of 1632 appears the outline of Lake Superior entering Lake Huron by the “Sault de Gaston,” as he calls the present Sault Ste. Marie. If one rejects the evidence of Brulé’s voyage, which rests upon inference chiefly,
