On the 20th of August the voyagers, with great difficulty, passed the Rapids des Moines. These are eleven miles in extent; and, with successive ledges and shoals, reach from shore to shore, across the bed of the river. Mr. Pike had here an interview with four chiefs, and fifteen men of the Sac nation, accompanied by a French interpreter, and an agent who had been sent from the United States to teach them agriculture. These men assisted him in his progress up the Rapids; and, in recompense for the service, they were presented with some tobacco, knives, and whiskey.

At some distance beyond the Rapids the voyagers had a beautiful prospect, at least forty miles in extent, down the river. Their average daily progress appears to have been betwixt twenty and thirty miles.

Above the river Jowa, which is one hundred and fifty yards wide at its mouth, the shore of the Mississippi consists of high prairie, with yellow clay-banks, and, in some places, banks of red sand: the western shore also is prairie, but bounded by wood. About ten miles up the Jowa is a village of Jowa Indians. This people subsist chiefly by hunting, but they cultivate some corn-land. Their chief residence is on the small streams in the rear of the Mississippi. From the Jowa to Rock river, there are, on the west, beautiful prairies, and, in some places, rich land, with black walnut and hickory timber.

On the 28th of August the vessel was much injured in passing up a series of rapids nearly eighteen miles in extent, and, in some places, reaching from shore to shore. Four days after this they arrived in the vicinity of some extensive lead-mines, which belonged to a Frenchman named Dubuque. The only animals they had hitherto seen were a few wild turkeys and some deer.

From the lead-mines to Turkey river, the Mississippi continues nearly of the same width, and the banks, soil, and productions appear precisely similar. On the bank of the Turkey river is a village of Reynard Indians, who raise there a considerable quantity of corn. The Reynards reside in three villages on the Mississippi, two of which Mr. Pike had already past. They grow corn, beans, and melons; and they annually sell many hundred bushels of corn to the inhabitants of the United States.

On the 2d of September, Mr. Pike and some of his men landed for the purpose of shooting pigeons; but the guns were no sooner fired, than a party of Indians, who were on shore at a little distance, ran to the water, and escaped in their pirogues or canoes, with great precipitation. After this the voyagers passed the mouth of the Ouisconsin river, which enters the Mississippi in latitude 43 degrees 44 minutes, and is nearly half a mile wide. This river is an important source of communication with the great American lakes, and is the route by which all the traders of Michillimackinac convey their goods to the Mississippi.

On the 6th of September, a council was held with a party of Puant or Winebagoe Indians, and one of the Sioux chiefs. The former occupy seven villages, and are supposed to be a nation who originally emigrated from Mexico, to avoid the oppression of the Spaniards. They are reputed to be brave; but their bravery resembles the ferocity of tigers, rather than the deliberate resolution of men. They are so treacherous that, it is said, a white man should never lie down to sleep in their villages, without adopting the utmost caution to preserve himself from injury. The Sioux are a powerful nation, the dread of whom is extended over all the adjacent country. They are divided into numerous bands, headed by celebrated chiefs. Few of them cultivate land; but they chiefly live on the production of the chase, and on a kind of bread which they make from wild oats. This species of grain is here produced in such abundance, that a sufficiency for their subsistence is easily collected in the autumn, without any trouble whatever in cultivating the land.

Not long after their interview with these Indians, the voyagers reached the Prairie des Chiens. The houses of this village, about eighteen in number, are arranged in two streets, along the front of a marsh. They are chiefly built of wood; are daubed on the outside with clay, and white-washed within. The furniture in most of them is decent, and, in those of the most wealthy inhabitants, displays a considerable degree of taste. The Prairie des Chiens was first settled under the protection of the English government, in the year 1783; and derives its name from a family of Reynards, who formerly lived there, and were distinguished by the appellation of Dog Indians. It is a place of resort for Indian traders and others, who reside in the interior. Mr. Pike here engaged two interpreters to accompany him; one of whom was to perform the whole voyage, and the other to sail with him as high as the falls of St. Anthony.

On the 9th of September he had an interview with a party of Sioux Indians. When he went towards the shore to meet them, they saluted him by firing three rounds from their muskets, loaded with ball. On landing, Mr. Pike was met by the chief, and invited to his lodge. This invitation he complied with, having first stationed some of his men as guards, to protect him in case of danger. In the lodge he found a clean mat and a pillow arranged for him to sit upon; and the complimentary pipe of peace was placed before him, on a pair of small crutches. The chief sate at his right hand, and the interpreter at his left. After they had satisfied each other of their mutual good wishes, and Mr. Pike had accepted the pipe, dinner was prepared. This consisted of wild rye and venison.

Mr. Pike was afterwards conducted by the chief to a dance, the performance of which was accompanied by many curious gestures. Men and women danced indiscriminately. They were all dressed in the gayest manner imaginable. Each had, in his hand, a small skin of some kind of animal. They frequently ran up, pointed their skin, and gave a puff with their breath; on which the person blown at fell, and either appeared lifeless, or in great agony; but afterwards slowly recovered, rose, and joined in the dance. This was understood to be of a religious description; and the Indians believed that they actually puffed, into each others bodies, something which occasioned them to fall. For persons to be permitted to take a part in these dances, it was requisite that they should make valuable presents to the society, give a feast, and be admitted with great ceremony. When Mr. Pike returned to his boat, he sent for the chief, and presented him with a quantity of tobacco, four knives, half a pound of vermilion, a quart of salt, and several gallons of spirits.
