Our first thought had been a suspicion of treachery, but we now saw that the Cheyennes had faced toward the hills, and, following their gaze, we beheld coming down their trail, and upon the tracks of our wagon, another band of mounted Indians. It soon became clear to us that the Pawnees, the Wolf's failure to find whom had made that noble red man feel "heap bad," were coming to find him. We counted them riding along, twenty-five in all--inferior in numbers, it was true, but superior to the Cheyennes in respect to their arms, so that, upon the whole, the two forces now about to come together were not unevenly matched. The Pawnees live beyond the Platte, and for years have been friendly to the whites, even serving in the wars against the other tribes on several occasions. What a stir there was in the late peaceful valley! The buffalo that were lately feeding along the brow of the plateau had all fled, and here right before us were sixty-five native Americans, bent upon killing each other off, directly under the eyes of their traditional destroyer, the white man. The Professor said it forcibly suggested to his mind some of the fearful gladiatorial tragedies of antiquity. Sachem responded that he wasn't much of a Roman himself, but he could say that in this show he was very glad we occupied the box-seat, the safest place anywhere around there; and we all decided that it must be a face-to-face fight, in which neither party dare run, as that would be disorganization and destruction. It was strange to see these wild Ishmaelites of the plains warring against each other. Over the wide territory, broad enough for thousands of such pitiful tribes, they had sought out each other for a bloody duel, like two gangs of pirates in combat on mid-ocean; and, like them, if either or both were killed, the world would be all the better for it. It was clearly what would be called, on Wall street, a "brokers' war," in which, when the operators are preying on each other, outsiders are safe. While we were looking, a wild, disagreeable shout came up from the twenty-five Pawnees, as they charged down into the valley, which was promptly responded to by fierce yells from the forty Cheyennes. "Let it be our task to bury the dead," said the Professor, looking toward the wagon in which rested his geological spade. "It is extremely problematical whether any of these red men will go out of the valley alive." And thus another wonderful change had come over the spirit of our dream. From being a scientific and sporting expedition, we had been suddenly metamorphosed into a gang of sextons, who, in a valley among the buffaloes, were witnessing an Indian battle, and waiting to bury the slain.
