"The Medicine of the Arrows depended on the Mysteries which are made in the camp before the Arrows go out. But if any one goes out from the camp toward the enemy before the Mysteries are completed, the protection of the Arrows is destroyed. Thus it happened when the Potawatami helped the Kitkahhahki, and the Cheyennes were defeated. This was my doing, mine and Red Morning and a boy of the Suh-tai who had nobody belonging to him. "We three were like brothers, but I was the elder and leader. I waited on War Bonnet when he went to the hunt, and learned war-craft from him. That was how it was with us as we grew up,--we attached ourselves to some warrior we admired; we brought back his arrows and rounded up his ponies for him, or washed off the Medicine paint after battle, or carried his pipe. "War Bonnet I loved for the risks he would take. Red Morning followed Mad Wolf, who was the best of the scouts; and where we two went the Suh-tai was not missing. This was long after we had learned all the tricks of the Ho-He by fighting them, after the Iron Shirts brought the horse to us, and we had crossed the Big Muddy into this country. "We were at war with the Pawnees that year. Not," said the Dog Chief with a grin, "that we were ever at peace with them, but the year before they had killed our man Alights-on-the-Cloud and taken our iron shirt." "Had the Cheyennes iron shirts?" Oliver was astonished. "Alights-on-the-Cloud had one. When he rode up and down in front of the enemy with it under his blanket, they thought it great Medicine. There were others I have heard of; they came into the country with the men who had the first horses, but this was ours. It was all fine rings of iron that came down to the knees and covered the arms and the head so that his long hair was inside. "It was the summer before we broke the Medicine of the Arrows that the Tsis-tsis-tas had gone out against the Pawnees. Arapahoes, Sioux, Kiowas, and Apaches, they went out with us. "Twice in the year the Pawnees hunted the buffaloes, once in the winter when the robes were good and the buffaloes fat, and once in the summer for food. All the day before we had seen a great dust rising and all night the ground shook with the buffaloes running. There was a mist on the prairie, and when it rose our scouts found themselves almost in the midst of the Pawnees who were riding about killing buffaloes. "It was a running fight; from noon till level sun they fought, and in the middle of it, Alights-on-the-Cloud came riding on a roan horse along the enemy line, flashing a saber. As he rode the Pawnees gave back, for the iron shirt came up over his head and their arrows did him no harm. So he rode down our own line, and returning charged the Pawnees, but this time there was one man who did not give back.
