The next morning we had a specimen of the false alarms to which all parties in these wild regions are subject. Proceeding up the valley, objects were seen on the opposite hills, which disappeared before a glass could be brought to bear upon them. A man who was a short distance in the rear, came springing up in great haste, shouting "Indians! Indians!" He had been near enough to see and count them, according to his report, and had made out twenty-seven. I immediately halted; arms were examined and put in order; the usual preparations made; and Kit Carson, springing upon one of the hunting horses, crossed the river, and galloped off into the opposite prairies, to obtain some certain intelligence of their movements. Mounted on a fine horse, without a saddle, and scouring bare-headed over the prairies, Kit was one of the finest pictures of a horseman I have ever seen. A short time enabled him to discover that the Indian war-party of twenty-seven consisted of six elk, who had been gazing curiously at our caravan as it passed by, and were now scampering off at full speed. This was our first alarm, and its excitement broke agreeably on the monotony of the day. At our noon halt, the men were exercised at a target; and in the evening we pitched our tents at a Pawnee encampment of last July. They had apparently killed buffalo here, as many bones were lying about, and the frames where the hides had been stretched were yet standing. The road of the day had kept the valley, which is sometimes rich and well timbered, though the country generally is sandy. Mingled with the usual plants, a thistle (_carduus leucographus_) had for the last day or two made its appearance; and along the river bottom, _tradescantia_ (virginica) and milk plant (_asclepias syriaca_) [Footnote: This plant is very odoriferous, and in Canada charms the traveler, especially when passing through woods in the evening. The French there eat the tender shoots in the spring, as we do asparagus. The natives make a sugar of the flowers, gathering them in the morning when they are covered with dew, and collect the cotton from their pods to fill their beds. On account of the silkiness of this cotton, Parkinson calls the plant Virginian silk.--_Loudon's Encyclopaedia of Plants_. The Sioux Indians of the Upper Platte eat the young pods of this plant, boiling them with the meat of the buffalo.] in considerable quantities.
