Above the Platte, the scenery of the Missouri becomes much more interesting. The bluffs on each side are more elevated and abrupt, and being absolutely naked, rising into conic points, split by innumerable ravines, they have an imposing resemblance to groups of high granitic mountains, seen at a distance. The forests within the valley are of small extent, interspersed with wide meadows covered with carices and cyperaceæ, with some species of limnetis, polypogon, and arundo, sometimes sinking into marshes occupied by sagittarias, alismas, and others of the hydrocharidæ. The woodlands here, as on the whole of the Missouri below, are filled with great numbers of pea vines,[171] which afford an excellent pasturage for horses and cattle. The roots of the apios tuberosa were much sought after, and eaten by the soldiers, who accompanied us in our ascent. They are little tubers about half an inch in diameter, and when boiled are very agreeable to the taste. Two and a half miles above the mouth of the Platte, and on the same side, is that of the Papilion, a stream of considerable length, but discharging little water.[172] Here we found two boats belonging to the Indian traders at St. Louis. They had passed us some days before, and were to remain for the winter at the mouth of the Papilion, to trade with the Otoes, Missouries, and other Indians. [pg221]
The banks of the Missouri, above the Platte, have long been frequented by the Indians, either as places {136} of permanent or occasional residence. Deserted encampments are often seen. On the north-east side, near the mouth of Mosquito river, are the remains of an old Ioway village. Four miles above, and on the opposite side, was formerly a village of the Otoes. On the 17th of September we arrived at the trading establishment of the Missouri Fur Company, known as Fort Lisa, and occupied by Mr. Manuel Lisa, one of the most active persons engaged in the Missouri fur trade. We were received by a salute from this establishment, and encamped a little above, on the same side of the river.[173]
{137} CHAPTER VIII
Winter cantonment near Council Bluff—Councils with the Otoes, Missouries, Ioways, Pawnees, &c.
The position selected for the establishment of winter quarters for the exploring party, was on the west bank of the Missouri, about half a mile above Fort Lisa, five miles below Council Bluff, and three miles above the mouth of Boyer's river.[174] At this place we anchored on the 19th[pg222] of September, and in a few days had made great progress in cutting timber, quarrying stone, and other preparations for the construction of quarters.
Cliffs of sparry limestone rise in the rear of the site we had selected, to an elevation of near three hundred feet.[175] At times of low water, strata of horizontal sandstone are disclosed in the bed of the Missouri. These pass under and support the limestone. Both these strata probably extend in connexion, some distance to the west; but as they are deeply covered with soil, we could not accurately ascertain their boundary in that direction. On the map accompanying this work, we have traced a line running from the Canadian river of the Arkansa, to the Elk Horn, between 96° and 98° west longitude, and marking what we supposed nearly the westernmost limit of the horizontal limestones, and the argillaceous sandstones, disclosed in the beds of the larger rivers.
{138} Both these strata embrace numerous relics of marine animals, many of which we collected.[176]
Immediately after our arrival, an interpreter had been sent across the country, to intercept the traders then on their way to the Pawnees, with considerable quantities of merchandize. It was thought proper to suspend all intercourse with those Indians, until an adjustment of the recent difficulties should take place. In addition to the outrage committed on Mr. Say's party, they had made prisoners of two white hunters from the Arkansa, a father and son, who had been found hunting in the Indian territories. These men had been liberated through the interference of some of the members of the Missouri Fur Company, and had recently arrived at Fort Lisa. During their captivity, they had been treated with such severity by the Pawnees, that they had often entreated an end might be put to their lives.[pg228]
