It was not till the voyagers had descended sixty leagues of the great stream that they discovered any signs of the presence of man; but at length, observing on the right bank of the river a foot-track, they followed it for six miles, and arrived at a horde _(bourgade),_ situated on a river called by the natives Moingona, an appellation afterward corrupted into "Riviere des Moines." Seeing no one, the visitors hollowed lustily, and four old men answered the call, bearing in hand the calumet of peace. "We are Illinois," said the Indians: "you are our fellow-men; we bid you welcome." They had never before seen any whites, but had heard mention of the French, and long wished to form an alliance with them against the Iroquois, whose hostile excursions extended even to their country. They were glad to hear from Joliet that the colonists had lately chastised those whom no others could vanquish, and feasted the visitors, to manifest their gratitude as well as respect. The chief of the tribe, with some hundreds of his warriors, escorted the party to their canoes; and, as a mark of parting esteem, he presented a calumet, ornamented with feathers of various colors; a safe-conduct this, held inviolable among the aborigines. The voyagers, again on their way, were forewarned of the confluence of the Missouri with the main stream, by the noise of its discharging waters. Forty leagues lower, they reached the influx of the Ohio, in the territory of the Chouanows. By degrees the region they traversed changed its aspect. Instead of vast prairies, the voyagers only saw thick forests around them, inhabited by savages whose language was to them unknown. In quitting the southern line of the Ohio, they left the Algonquin family of aborigines behind, and had come upon a region of nomads, the Chickasaw nation being here denizens of the forest. The Dacotas, or Sioux, frequented the riverain lands, in the southern region watered by the great flood. Thus interpreters were needed by the natives, who wished to parley from either bank of the Mississippi, each speaking one of two mother-tongues, both distinct from those of the Hurons and Algonquins, much of the latter being familiar to Joliet and others of the party.
