By this time we thought we understood why a kind Providence had caused that cottonwood tree to lodge at such an angle that a buffalo could not climb it, but we could--and we did. Getting ourselves safely into the fork of the tree, we continued to shoot from our coign of vantage till the big fellow dropped. When he ceased to kick or give any sign of belligerency, we came down and approached him, carefully. Then we dressed him, or as much of him as we could carry in two bags that we had strapped behind our saddles, and rejoined the train after our people had gone into camp for the night. [Illustration: Chimney Rock] We had our first buffalo steak for supper that night. We also had the satisfaction of observing signs of jealousy on the part of the other men who had never killed a buffalo. One of the first natural curiosities we saw was Chimney Rock; a vertical column of sandstone something like forty feet high, with a rugged stone bluff rising abruptly near it. Its appearance, from our distant view, resembled a stone chimney from which the building had been burned away, as it stood, solitary on the flat earth at the south side of the Platte River, we traveling up the north shore. Such a time-chiseled monument was a novelty to us then. To the early emigrants it was the first notable landmark. While some distance farther west, as we scaled the higher slopes, we could see to the southward the snow-capped peaks of that region which long afterward was taken from western Nebraska to become the Territory of Colorado, and later still, the State of that name. Looking over and past the locality where, more than a year thereafter, the town of Denver was laid out, we saw, during several weeks, the summit of Pike's Peak, hundreds of miles away. One evening when we were going into camp we were overtaken by a man trundling a push-cart. This vehicle had between its wheels a box containing the man's supplies of food and camp articles, with the blankets, which were in a roll, placed on top; all strapped down under an oilcloth cover. With this simple outfit, pushed in front of him, this man was making his way from one of the Eastern States to California, a distance of more than three thousand miles. He was of medium size, athletic appearance, with a cheerful face. He visited us overnight. The next morning he was invited to tie his cart behind one of our wagons and ride with us. He replied that he would be pleased to do so, but was anxious to make all possible speed, and felt that he could not wait on the progress of our train, which was somewhat slower than the pace he maintained. It was said that he was the first man who made the entire trip on foot and alone, from coast to coast, as we were afterwards informed he succeeded in doing.
