Father Marquette and M. Joliet had astronomical instruments with which they ascertained, with much accuracy, the latitude of all their important stopping places. As they state that the two villages, which they visited, were on the western side of the Mississippi, at the latitude of forty degrees north, and upon the banks of a stream flowing into the Great River, it is supposed that these villages were upon the stream now called Des Moines, which forms a part of the boundary between Iowa and Missouri. The Indians called the villages Pe-ou-a-sea and Moing-wena. They were probably situated about six miles above the present city of Keokuk.

It was three o'clock in the afternoon, of a day near the end of sunny, blooming June, when our voyagers resumed their adventurous tour. Nearly the whole tribe they had visited stood upon the bank to bid them adieu. They floated along through a very dreary country of precipitous rocks and jagged cliffs, which quite shut out from their view the magnificent prairie region which was spread out beyond this barrier.

Upon the smooth surface of one of these rocks, apparently inaccessible, they saw, with surprise, two figures painted in very brilliant colors and with truly artistic outline. They thought that the painting would have done honor to any European artist. The figures were of two rather frightful looking monsters, about the size of a calf, in red, green, and black. Stoddard, in his history of Louisiana, says that these painted monsters, between the Missouri and the Illinois Rivers, still remain in a good degree of preservation.

"As we were discoursing of them," writes Father Marquette, "sailing gently down a beautiful, still, clear water, we heard the noise of a rapid, into which we were about to fall. I have seen nothing more frightful. A mass of large trees, entire, with branches, real floating islands, came rushing from the mouth of the river Pekitunoüì, so impetuously that we could not, without great danger, expose ourselves to pass across. The agitation was so great that the water was all muddy, and could not get clear."

This was the rush and the roar of the incoming billows of the terrible Missouri, the most tremendous river upon this globe. It enters the Mississippi through a channel half a mile in breadth, rushing down with a sort of maniacal fury, from its sources among the Rocky Mountains at the distance of three thousand and ninety-six miles. Its whole course, from its rise to its entrance into the Gulf of Mexico, is four thousand three hundred and forty-nine miles. More than two hundred and fifty years after this, Mr. George Catlin ascended this river in the first steamer which ever ventured to breast its torrent.

It took the steamer three months to ascend to the mouth of the Yellowstone, two thousand miles from the city of St. Louis. At this point the American Fur Company had erected a very substantial fort, three hundred feet square, for the protection of their property against the savages. The banks of the stream were lined with the villages of the Indians. Their wigwams were of a great variety of structure. The scenes presented were astonishing in their wild and picturesque aspect. Crowds of weird-like savages would often be collected on the bluffs, watching the appalling phenomenon of the passing steamer.

The Missouri is different, perhaps, from any other river in the world. Its boiling, turbid waters rush impetuously on, in an unceasing current, for hundreds of leagues, with scarcely a cove, an eddy, or any resting place where a canoe can be tranquilly moored. The Indian name of the river signifies Muddy Water. It is so opaque, like a cup of chocolate, that a newly coined shilling, placed in a tumbler, cannot be seen through the eighth part of an inch of the water.

For nearly a thousand miles the whole bed of the stream was impeded with gigantic trees, torn from the rich alluvial banks, forming snags and sawyers and rafts, through which, often with difficulty, the steamer cut her way. Every island and sandbar was covered with dreary looking masses of driftwood of every conceivable variety.

This desolate and savage aspect of the rushing flood is much relieved by the aspect of marvellous beauty often presented on the banks. It was almost a fairy scene. Hills and vales, bluffs and ravines, were continually presented in successions of sublimity and beauty which charmed the eye. Prairies were often spread out before them of boundless expanse, upon which vast herds, often numbering thousands, of buffaloes, elks, and antelopes, were seen grazing. In the gloomy forests, wolves were roaming. Mountain goats bounded over the cliffs. And at times, the air seemed darkened with the myriad birds which rose from the tall grass.

There was one twelve-pound, and three or four eight-pound cannon on board the steamer. At every village which was passed, the banks would be crowded with the astounded natives. Mischievously, the captain would order all the cannon to be simultaneously discharged. The effect upon the terrified savages was ludicrous in the extreme. They were all thrown into utter consternation. The more devout threw themselves upon the ground, and, hiding their faces, cried to the Great Spirit for protection. The cowards, with the women and the children, ran screaming back into the prairie, or behind the hills. Occasionally, a little band of veteran warriors, the bravest of the brave, would stand their ground, ready to meet the terrors of even a supernatural foe.
