Aside from the indefinite phrases of this paper, it is characterized by so many geographical errors that it would possess little value without the support of the following statement of La Salle himself: In the year 1667 and following years he La Salle made many voyages, at much expense, in which he was the first discoverer of much country south of the great lakes, between them and the great river, Ohio. He followed it to a place where it falls from a great height into marshes, in latitude 37°, after having been enlarged by another very large river, which comes from the north, and all these waters, according to appearances, discharge into the Gulf of Mexico, and here he hopes to find a communication with the sea. No conjecture respecting La Salle’s operations on the Ohio has yet been formed that reconciles these conflicting accounts. In nothing direct from his pen does La Salle refer to the desertion of his men after leaving the falls of the Ohio. According to the supposed recital of Armand de Bourbon, he had made a long journey from thence by land, the direction of which is not known. He may have been at that time in Kentucky or Tennessee, Indiana, Illinois, or Ohio. If he proceeded westerly he was constantly increasing the distance from Montreal, and whether he was north or south of the Ohio it is scarcely credible that he should find his way back alone in the winter of 1669–70. In the spring of 1681 he made that sad trip from “Crèvecœur” to Niagara, with an Indian and four men, which occupied sixty-five days. It would consume fully as much time to return from the falls of the Ohio. He could not have examined the country near the river, below the falls, or he would not have reported that it is a vast marsh, with intricate channels, along which it flowed a great distance before uniting in a single bed. He could not have traveled far west of the meridian of the falls without hearing of the Mississippi, and making an effort to reach it, for it was only through this river that he then expected to reach the Red Sea on the route to China. La Salle could not have explored the falls very minutely, and have spoken of them as very high, nor of the country below as a vast marsh with numerous and intricate channels. If, in his land journey, he had gone in a northwesterly direction, he would have struck the Wabash or its main branches in about one hundred and twenty-five miles. In a southwesterly direction, the Cumberland and the Tennessee are rivers of equal magnitude, the waters of which he must have encountered in a few days’ travel.
