In August, 1867, we were sent to Fort Lyon, and on this trip we saw thousands of buffaloes. The breeding season was now approaching its close, and at night and early morning could be heard the constant, low thunder of the bulls, their grunting rising into a roar that was one of the most striking of the natural phenomena of the Plains country. The calves, by this time, were alert, active little fellows, closely guarded by their mothers. Later in the season, all the bulls would segregate themselves from the cows, to range apart until the next breeding season. West of Fort Dodge we saw Indians in war paint, and expected to be attacked, but the rascals veered round us and went on their way. Fort Hayes was on a tributary of the Smoky Hill River; old Fort Zarah, on Walnut Creek; Fort Larned on Pawnee Fork, and Fort Harker on Big Creek. All these forts were being remodeled and improved. In this way we put in all that summer, hauling supplies to one fort or the other, and when not engaged in this, we hauled rock for the foundations of the buildings. Along in October, 1867, while several Government trains were at Fort Harker, waiting for orders, we were notified to make ready to accompany a party of peace commissioners that had been authorized to treat with several of the main plains tribes of Indians in the Southwest, at Medicine Lodge, Kas. These negotiations were afterwards known as the Medicine Lodge Treaty. Like most other treaties with these tribes, it was soon broken. Several trains, with a part of ours, were to accompany this expedition. I was eager to go, but as no orders had been given to my outfit, I was fearful that I might be left behind. Here was the opportunity I had long looked for--to see a big gathering of Indians close at hand, without danger of getting scalped. I had almost given up in despair, when an orderly galloped up from headquarters, saying that two more wagons must be sent forward at once. It was now 6 o'clock in the evening. Simpson, our wagon-master, approached me and said: "Billy, you and Frickie (Frickie drove the wagon next to mine) get ready at once and go into Fort Harker." As a rule, nothing ever greatly excited me in my frontier days, but I am bound to admit that I was now going round and round, so overjoyed was I at my good luck. My agitation came near causing me to be left behind.
