Shea states, in his “Discovery and Exploration of the Mississippi,” that Nicolet descended the Wisconsin to the Mississippi. This opinion was adopted by Parkman in his “Jesuits in North America,” p. 166, but his later judgment is given in the “Discovery of the Great West.” A more careful examination of the evidence demonstrates the improbability that his travels extended farther than the Wisconsin, and in the opinion of Butterfield, the latest writer upon this voyage, he did not reach that river, but stopped at the country of the Mascoutins upon Fox River. Benjamin Sulté, a Canadian historical writer, in writing upon Nicolet, in his “Mélanges d’Histoire et de Littérature,” Ottawa, 1876, shows, for the first time, that this journey was probably made in 1634, instead of 1638 or 1639, as before thought. Sulté’s article with notes by L. C. Draper, is printed in the “Wisconsin Historical Society Collections,” vol. viii., pp. 188–194; also in the “Canadian Antiquarian,” vol. viii., pp. 157–164. Butterfield, who has carefully investigated the records, agrees with Sulté in assigning 1634 as the true date, and brings out additional, if not conclusive evidence to support this theory, in his monograph cited above. Margry, in the “Journal de l’Instruction publique,” 1862, under the caption, “Les Normands dans les Vallées de l’Ohio et du Mississipi,” describes Nicolet’s travels and Gravier’s “Découvertes et établissements de la Salle;” Harrisse’s “Notes pour servir à l’Histoire [etc.] de la Nouvelle France,” and Parkman’s “La Salle,” also give some account of the expedition. In 1642 Jogues and Raymbault, two missionaries, penetrated as far west as Sault Ste. Marie, at the outlet of Lake Superior. See account of this mission in the Jesuit Relation of 1642. Margry’s Collection, vol. i., pp. 45–47, contains a reprint of the narrative of this journey. See also Shea’s Charlevoix, vol. i., p. 137, for notice of the undertaking. The next recorded visit to the West is that of two French traders, who wintered upon the shores of Lake Superior in 1658. See the Jesuit Relation of 1659–60, and the extract in Margry’s Collection, vol. i., pp. 53–55, and translation in Smith’s Wisconsin, vol. iii., p. 20. Father Ménard began a mission at St. Theresa Bay, Lake Superior, in 1661. See Lallemant’s letter in the Relation of 1662–63. A translation of this letter is in Smith’s Wisconsin, vol. iii. See also Perrot’s “Mémoire sur les mœurs des sauvages,” Paris, 1864; Shea’s Charlevoix, vol. i., p. 49, and a note by Shea in _Historical Magazine_, vol. viii., p. 175. Ménard’s letter, written just before his departure for Lake Superior, with notes by E. D. Neill, may be found in the “Minnesota Historical Society Collections,” vol. i., pp. 135–138.
