At the close of the parade and review referred to, the officers and the ladies attended an Indian dance, given by the Pawnees, which climaxed a rather exciting day.
The following morning an expedition moved back to the Republican River, to curb the high spirits of a band of Sioux, who had grown boldly troublesome. This was the sort of service the Pawnees welcomed, as they and the Sioux were hereditary enemies.
At the journey's end, camp was made at the mouth of the Beaver, and the Sioux were heard from within the hour. A party of them raided the mules that had been taken to the river, and the alarm was given by a herder, who dashed into camp with an arrow sticking in his shoulder.
Will did not wait to saddle his horse, but the Pawnees were as quick as he, and both of them rather surprised the Sioux, who did not expect such a swift response. Especially were they surprised to find themselves confronted by their tribal foe, the Pawnee, and they fell back hastily, closely pressed by Will and his red allies. A running fight was kept up for fifteen miles, and when many of the Sioux had been stretched upon the plain and the others scattered, the pursuing party returned to camp.
Will himself, on a fine horse, had been somewhat chagrined at being passed in the chase by a Pawnee on an inferior-looking steed. Upon inquiring of Major North, he found that the swifter horse was, like his own, government property. The Pawnee was much attached to his mount, but he was also fond of tobacco, and a few pieces of that commodity, supplemented by some other articles, induced him to exchange horses. Will named his new charge "Buckskin Joe," and rode him for four years. Joe proved a worthy successor to Brigham for speed, endurance, and intelligence.
This was the first adventure that Will and the Pawnees had pursued together, and they emerged with an increased esteem for each other. Not long afterward, Will's skill as a buffalo-hunter raised the admiration of the Indians to enthusiasm.
Twenty Pawnees that circled around one herd of buffaloes killed only twenty-two, and when the next herd came in view Will asked Major North to keep the Indians in the background while he showed them a thing or two. Buckskin Joe was a capital buffalo-hunter, and so well did he perform his part that Will brought down thirty-six, about one at every shot.
The Pawnees were delighted. They held it considerable of an achievement to kill two or three of the monarchs of the plains at a single run, and Will's feat dazzled them. He was at once pronounced a great chief, and ever after occupied a high place in their regard.
Moving up the Republican River, the troops went into camp on Black Tail Deer Fork. Scarcely were the tents pitched when a band of Indians were seen sweeping toward them at full speed, singing, yelling, and waving lances. The camp was alive in an instant, but the Pawnees, instead of preparing for defense, began to sing and yell in unison with the advancing braves. "Those are some of our own Indians," said Major North; "they've had a fight, and are bringing in the scalps."
And so it proved. The Pawnees reported a skirmish with the Sioux, in which a few of the latter had been killed.
