After they were seated, the calumet[130-18] was presented to them, and while the old men were smoking for their entertainment, the chief of all the Illinois tribes sent them an invitation to attend a council at his village. They were treated by him with great kindness, and Father Marquette, having explained to him the motives of this voyage, enforcing each part of his speech with a present, the chief in reply expressed his approbation; but urged him, in the name of the whole nation, not to incur the risks of a further voyage, and rewarded his presents by the gift of a calumet.

The council was followed by a feast, consisting of four courses, from each of which they were fed with much ceremony; and afterwards they were conducted in state through the village, receiving many presents of girdles and garters from the natives. The following day, they took leave of the chief, promising to return in four moons, and were accompanied to their canoes, with every demonstration of joy, by more than six hundred savages.

Before leaving this nation, Father Marquette remarked some of their peculiarities. The name Illinois, in the native language, signifies men, as if implying thereby, that other tribes are brutes in comparison, which in some sense Father Marquette thought to be true, as they were more civilized than most of the tribes. Their language, on the borders of the river, was a dialect of the Algonquin, and was understood by Father Marquette. In the form of their bodies the Illinois were light and active. They were skilful in the use of arms, brave, but mild and tractable in disposition. They were entirely ignorant of the use of leather, and iron tools, their weapons being made of stone, and their clothing of the skins of wild beasts. The soil was rich and productive, and game abundant.

After this peaceful interview with the natives, the voyagers embarked again, and passed down the stream, looking out for the river Pekitanoni (Missouri), which empties into the Mississippi from the northwest.

They observed high and steep rocks, on the face of which were the figures of two monsters, which appeared as if painted in green, red, and blue colors; frightful in appearance, but so well executed, as to leave Father Marquette in doubt, whether they could be the work of savages, they being also at so great a height on the rocks as to be inaccessible to a painter.[131-19]

As they floated quietly down a clear and placid stream, conversing about the figures they had just passed, they were interrupted by the sound of rapids before them; and a mass of floating timber, trunks and branches of trees, was swept from the mouth of the Pekitanoni with such a degree of violence, as to render the passage dangerous. So great was the agitation, that the water was thereby made very muddy, and it did not again become clear.[132-20] The Pekitanoni is described as a large river flowing into the Mississippi from the northwest, with several villages on its banks.

At this place Father Marquette decided, that, unless the Mississippi altered its previous course, it must empty its waters into the Gulf of Mexico; and he conjectured from the accounts of the natives, that, by following the stream of the Pekitanoni, a river would be discovered, which flowed into the Gulf of California.[132-21]

About twenty leagues south of the Pekitanoni, and a little more to the southeast, they discovered the mouth of another river, called Ouabouskigou (Ohio), in the latitude of thirty-six degrees; a short distance above which, they came to a place formidable to the savages, who, believing it the residence of a demon, had warned Father Marquette of its dangers. It proved nothing more than a ledge of rocks, thirty feet high, against which the waves, being contracted by an island, ran with violence, and, being thrown back with a loud noise, flowed rapidly on through a narrow and unsafe channel.
