Mul-tal-la explained the problem that confronted him, and the boys saw it was both difficult and dangerous. His plan was to press on till they arrived at the entrance to the pass, and then, instead of waiting until morning, do the utmost traveling possible by night. The Shoshones would not expect this. Therefore, if all went well, our friends would gain a good start and, by keeping it up as long as they could, might throw their enemies so far to the rear that they would be eluded. The Blackfoot thought they could reach the comparatively level country beyond at the end of three days, provided they made good use of the nights, which, you will remember, were partly lit by the moon, and provided also the weather continued fair. “The smoke of this fire will tell Black Elk where we are,” remarked George Shelton, when they were about to resume their journey. “Yes; had Mul-tal-la seen the signal of Black Elk the fire would not have been started, but it is too late now.” “It seems to me,” said Victor, “that since you have located Black Elk and his party, the only thing left is to keep a lookout for the Shoshones in front.” “My brother speaks the words of wisdom.” “Thanks—and now, Mul-tal-la, why not go by that pass you have been talking about and take a new one through the mountains?” The Blackfoot explained that that was the question he had been turning over in his mind, but the plan could not be followed, because he had no knowledge of any other path. There might be none, or, at best, he would have to spend a long time in hunting for it, and when found, they were likely to be turned back by obstructions of which they could know nothing until they faced them. The conclusion was therefore clear: they must use the old pass with which he was familiar. But the Blackfoot had a little trick in mind, which he explained to his friends. They would select a camping site among the foothills near where they would have to make the change of route to enter the mountains. They would start another fire, whose smoke would give their enemies the impression that they had halted for the night. The Shoshones, following the rule of their race, were not likely to molest the travelers until the night was well advanced, and by that time Mul-tal-la hoped to be beyond reach. Care and skill and not a little good fortune were necessary to success, but the faithful guide was hopeful.
