On the evening of the 20th of May, we encamped in a low, muddy bottom, overgrown with nettles and phacelias; but the only place we could find combining the three requisites—grass for our horses, and wood and water for ourselves. Here we were so tormented by the mosquitoes, harassed and goaded by the wood-ticks, {108} that we were glad to seek relief by mounting our horses, at the earliest appearance of light on the following morning. The dew had been so heavy, that it was falling in drops from the grass and weeds where we had lain, and our blankets were dripping as if they had been exposed to a shower. We proceeded on our course about thirty miles, and encamped early in the afternoon. Having ascended Grand river nearly to the point, where we believed Field's trace must cross it, we directed our course more to the west, and had already crossed several streams running to the south, supposed to be the upper branches of the Little Platte. The utmost uniformity prevails in the appearance of the country about the sources of the Little Platte, Nishnebottona, and other northern tributaries of the Missouri. Near one of these small rivers we discovered the trace of an Indian war party, which appeared to have passed very recently towards the Missouri. After our arrival at Council Bluff, we had farther information of these Indians, who were a war party of Sauks and Foxes from the Mississippi, and had committed many depredations upon the Missouri Indians, and some upon the whites. We were considered very fortunate in not having fallen in with them, as it was believed, they would not have hesitated to rob, and perhaps destroy, any party of whites as weak as ours. Remains of bisons, as bones, horns, hoofs, and the like, are often seen in these plains; and in one instance, in a low swamp surrounded by forests, we discovered the recent track of a bull; but all the herds of these animals have deserted the country on this side of Council Bluff. The bones of elk and deer are very numerous, particularly about certain places, which, from the great number of tent poles, scaffolds, &c. appear to be old Indian hunting camps; and the living animals are still to be found here in plenty. As we rode along these boundless meadows, {109} every object within several miles became visible; the smallest shrub rising a few inches above the surface of the green expanse, could be seen at a mile distant.[66] Some large agarics, and a gigantic lycoperdon, peculiar to these regions, are the most conspicuous objects by which the uniformity of the plains is varied; and these may be seen sometimes at the distance of two or three miles. [66] A ceanothus, smaller than C. americana, the amorpha canescens, and the symphoria racemosa, are almost the only shrubs seen in the prairies.—JAMES.
