We now come to the great map of Franquelin, the most remarkable of all the early maps of the interior of North America, though hitherto completely ignored by both American and Canadian writers. It is entitled _"Carte de la Louisiane ou des Voyages du St de la Salle et des pays qu'il a decouverts depuis la Nouvelle France jusqu'au Golfe Mexique les annees 1679, 80, 81 et 82. par Jean Baptiste Louis Franquelin. l'an 1684. Paris."_ Franquelin was a young engineer, who held the post of hydrographer to the king, at Quebec, in which Joliet succeeded him. Several of his maps are preserved, including one made in 1681, in which he lays down the course of the Mississippi,--the lower part from conjecture,--making it discharge itself into Mobile Bay. It appears from a letter of the Governor, La Barre, that Franquelin was at Quebec in 1683, engaged on a map which was probably that of which the title is given above, though, had La Barre known that it was to be called a map of the journeys of his victim La Salle, he would have been more sparing of his praises. "He" (Franquelin), writes the Governor, "is as skilful as any in France, but extremely poor and in need of a little aid from his Majesty as an Engineer: he is at work on a very correct map of the country which I shall send you next year in his name; meanwhile, I shall support him with some little assistance."-- _Colonial Documents of New York_, ix. 205. The map is very elaborately executed, and is six feet long and four and a half wide. It exhibits the political divisions of the continent, as the French then understood them; that is to say, all the regions drained by streams flowing into the St. Lawrence and the Mississippi are claimed as belonging to France, and this vast domain is separated into two grand divisions, La Nouvelle France and La Louisiane. The boundary line of the former, New France, is drawn from the Penobscot to the southern extremity of Lake Champlain, and thence to the Mohawk, which it crosses a little above Schenectady, in order to make French subjects of the Mohawk Indians. Thence it passes by the sources of the Susquehanna and the Alleghany, along the southern shore of Lake Erie, across Southern Michigan, and by the head of Lake Michigan, whence it sweeps north-westward to the sources of the Mississippi. Louisiana includes the entire valley of the Mississippi and the Ohio, besides the whole of Texas. The Spanish province of Florida comprises the peninsula and the country east of the Bay of Mobile, drained by streams flowing into the Gulf; while Carolina, Virginia, and the other English provinces, form a narrow strip between the Alleghanies and the Atlantic.
