Gradually enlarging, in a few days' march it became a river eighty yards in breadth, wooded with occasional groves of cottonwood. Our road was generally over level uplands bordering the river, which were closely covered with a sward of buffalo-grass.
On the 10th we entered again the buffalo range, where we had found these animals so abundant on our outward journey, and halted for a day among numerous herds, in order to make a provision of meat sufficient to carry us to the frontier.
A few days afterwards, we encamped, in a pleasant evening, on a high river prairie, the stream being less than a hundred yards broad. During the night we had a succession of thunder-storms, with heavy and continuous rain, and towards morning the water suddenly burst over the bank, flooding the bottoms and becoming a large river, five or six hundred yards in breadth. The darkness of the night and incessant rain had concealed from the guard the rise of the water; and the river broke into the camp so suddenly, that the baggage was instantly covered, and all our perishable collections almost entirely ruined, and the hard labor of many months destroyed in a moment.
On the 17th we discovered a large village of Indians encamped at the mouth of a handsomely wooded stream on the right bank of the river. Readily inferring, from the nature of the encampment, that they were Pawnee Indians, and confidently expecting good treatment from a people who receive regularly an annuity from the government, we proceeded directly to the village, where we found assembled nearly all the Pawnee tribe, who were now returning from the crossing of the Arkansas, where they had met the Kioway and Camanche Indians. We were received by them with the unfriendly rudeness and characteristic insolence which they never fail to display whenever they find an occasion for doing so with impunity. The little that remained of our goods was distributed among them, but proved entirely insufficient to satisfy their greedy rapacity; and, after some delay, and considerable difficulty, we succeeded in extricating ourselves from the village, and encamped on the river about 15 miles below.
[Footnote: In a recent report to the department, from Major Wharton, who visited the Pawnee villages with a military force some months afterwards, it is stated that the Indians had intended to attack our party during the night we remained at this encampment, but were prevented by the interposition of the Pawnee Loups.]
The country through which we had been traveling since leaving the Arkansas river, for a distance of 260 miles, presented to the eye only a succession of far-stretching green prairies, covered with the unbroken verdure of the buffalo-grass, and sparingly wooded along the streams with straggling trees and occasional groves of cottonwood; but here the country began perceptibly to change its character, becoming a more fertile, wooded, and beautiful region, covered with a profusion of grasses, and watered with innumerable little streams, which were wooded with oak, large elms, and the usual varieties of timber common to the lower course of the Kansas river.
As we advanced, the country steadily improved, gradually assimilating itself in appearance to the northwestern part of the state of Missouri. The beautiful sward of the buffalo-grass, which is regarded as the best and most nutritious found on the prairies, appeared now only in patches, being replaced by a longer and coarser grass, which covered the face of the country luxuriantly. The difference in the character of the grasses became suddenly evident in the weakened condition of our animals, which began sensibly to fail as soon as we quitted the buffalo-grass.
The river preserved a uniform breadth of eighty or a hundred yards, with broad bottoms continuously timbered with large cottonwood-trees, among which were interspersed a few other varieties.
While engaged in crossing one of the numerous creeks which frequently impeded and checked our way, sometimes obliging us to ascend them for several miles, one of the people (Alexis Ayot) was shot through the leg by the accidental discharge of a rifle--a mortifying and painful mischance, to be crippled for life by an accident, after having nearly accomplished in safety a long and eventful journey. He was a young man of remarkably good and cheerful temper, and had been among the useful and efficient men of the party.
After having traveled directly along its banks for 290 miles, we left the river, where it bore suddenly off in a northwesterly direction, towards its junction with the Republican fork of the Kansas, distant about 60 miles; and, continuing our easterly course, in about 20 miles we entered the wagon-road from Santa Fé to Independence, and on the last day of July encamped again at the little town of Kansas, on the banks of the Missouri river.
