There appears to be no uniformity in the spelling of the name of Groseilliers. Under May, 1662, is this entry: “I departed from Quebek on the 3d for Three Rivers; there met Des Grosillers, who was going to the Sea of the North. He left Quebek the night before with ten men.” Under August, 1663, is the following: “The 5th returned those who had been three years among the Outaoouac; nine Frenchmen went, and seven returned. The Father Menar and his man, Jean Guerin, one of our _donnés_, had died,—the Father Menar the 7th or 8th of August, 1661, and Jean Guerin in September, 1662. The party arrived at Montreal on the 25th of July, with thirty-five canoes and one hundred and fifty men.” Of Creuxius’ _Historia_ and its relations to the missionaries’ reports, there is an account in the next chapter. =1660-1680.=—The documents from the French archives in the Parliament Library at Ottawa, Canada (copies in manuscript), and those translated and printed in the _New York Col. Docs._, vol. ix., give much information on this period; and so do the _Jesuit Relations_, and the first volume of the Collections edited by Margry and published at Paris in 1875.[532] The _Mémoire sur les Mœurs, Coustumes, et Réligion des Sauvages de l’Amérique septentrionale, par Nicolas Perrot, publié pour la première fois par le R. P. J. Tailhan, de la Compagnie de Jésus_, Leipsic and Paris, 1864,[533] was examined by Charlevoix one hundred and fifty years ago, when it was in manuscript, and afforded him useful information. It is the only work referring to the traders at the extremity of Lake Superior between 1660 and 1670, and to the migrations of the Hurons from the Mississippi to the Black River, and from thence to Lake Superior. Much of interest is also derived from the _Histoire de l’Amérique septentrionale_. Par M. de Bacqueville de la Potherie, Paris, 1722, 4 vols.[534] =1680-1690.=—There are differences of statements regarding the Upper Mississippi Valley, but nevertheless much information of importance, in the letter of La Salle from Fort Frontenac, in August, 1682,[535] in Du Lhut’s _Mémoire_ of 1683, as printed by Harrisse,[536] and in Hennepin’s _Description de la Louisiane_.[537] Perrot, in the work already quoted, gives the best account of this region from 1683 to 1690. For the whole period of the exploration of the Great Lakes, the works among the secondary authorities of the chief value are Charlevoix in the last century, and Parkman in the present; but their labors are commemorated elsewhere.
