Continuing their descent, the confluence of the Arkansas with the Mississippi was attained. The voyagers were now under the thirty-third parallel of north latitude, at a point of the river-course reported to have been previously reached, from the opposite direction, by the celebrated Spanish mariner De Soto. Here the Illinois chief's present stood the party in good stead, for on exhibiting his ornate calumet they were treated with profuse kindness. Bread, made of maize, was offered by the chief of the horde located at the mouth of the Arkansas River. Hatchet-heads of steel, in use by the natives, gave intimation that they traded with Europeans, and that the Spanish settlements on the Bay of Mexico were probably not far off. The waxing summer heats, too, gave natural corroboration to the same inferences. The party had now, in fact, attained to a region without a winter, unless as such be reckoned that part of its year known as "the rainy season." It now became expedient to call a halt, for the stored provisions were beginning to fail, and chance supplies could not be depended upon in such a wilderness as the bold adventurers had already traversed; and they were still more uncertain as to what treatment they might receive from savage populations if they proceeded farther. One thing was made plain to their perceptions: the Mississippi afforded no passage to the East Indian seas. They rightly concluded, also, that it found its sea outlet in the Bay of Mexico, not the Pacific Ocean. They had therefore now done enough to entitle them to the grateful thanks of their compatriots, and for the names of their two leaders to take a permanent place in the annals of geographical discovery. The task of ascending the great river must have been arduous, and the return voyage protracted. Arrived at the point where it is joined by the Illinois, they left it for that stream, which, ascending for a part of its lower course, Pere Marquette elected to remain with the natives of tribes located near to its banks; while M. Joliet, with the rest of the party, passed overland to Chicago. Thence he proceeded to Quebec, and reported his proceedings to the Governor, M. Talon at that time being in France. This duty he had to perform orally, having lost all his papers when shooting the rapids of the St. Lawrence, above Montreal. He afterward drew up a written report, with a tracing of his route, from memory.
