The obscurity did not prevent the brothers gaining a good view of the five warriors, who surveyed them with unconcealed interest as they came into the trail and halted behind the Blackfoot and several paces from the nearest Shoshone. The strangers resembled the warriors who were the companions of Black Elk, the chief. Though he could not be certain, George believed that one at least whom they had met that morning was with the party before him. Mul-tal-la now told a remarkable story—so remarkable, indeed, that the boys could not credit it. These five Shoshones were the ones to whom Black Elk had signaled by means of his camp-fire, and to which they had replied later in the day. But the exchange of messages was meant as a friendly interference in behalf of the Blackfoot and his companions. The chief had good reason to believe that a hunting party of Cas-ta-ba-nas were in the mountains, and a meeting between them and the travelers was almost certain. The Cas-ta-ba-nas were a small tribe whose villages and hunting grounds were to the eastward of the principal range of the Rockies. They were small in numbers, but of warlike disposition, and were often engaged in hostilities with others of their race. They were wise enough, however, not to molest the Shoshones or Snakes, who were so much more numerous and powerful that they would have exterminated the whole tribe had provocation been given. It would not be far from the truth to say the Cas-ta-ba-nas were vassals of the Shoshones. It appeared to be the fate of the smaller tribe to become involved to a greater degree with the whites than were others of their race. This may have been because the most productive beaver-runs were in their section of the West, and consequently more trappers were drawn hither. There had been a fight the preceding winter between three white men and a party of Cas-ta-ba-nas, in which two of the latter were killed. This inflamed the anger of the tribe toward the palefaces. What more likely, therefore, than that, when they came upon a couple of the hated race under the escort of a single Blackfoot, they should destroy all three? Black Elk, therefore, as the extraordinary story ran, had signalled to the Shoshones to warn the Cas-ta-ba-nas that they must not molest the little party on their way through their country. If they violated the command Black Elk would make sure that they suffered therefor. This was the story told to the boys, and which impressed them as incredible. “I don’t believe a word of it,” said Victor, who did not hesitate to speak plainly, inasmuch as Mul-tal-la was the only Indian present who could understand his words; “do _you_?” “Mul-tal-la does not know; it may be true.” “How could Black Elk tell all this to another party of Shoshones by means of the smoke of his camp-fire?” asked George Shelton. “He could not.” “Then how did these people get his message?”
