“How about that?” broke in Victor, pointing to the westward, in which direction the pass extended.

The others turned and saw that which they had been hoping not to see. A spiral, oscillating line of smoke was creeping slowly upward in the clear air. Moreover, it was not more than half a mile distant. Although the reply of the Shoshones to their chief had been delayed, it had come at last. The warriors were on hand, and in the path which the travelers had intended to follow.

The three scanned the telltale column of vapor in silence. In the circumstances the glass could give no help. The interval was too brief and the object itself too ethereal and vague to call for any strengthening of vision. Finally George asked, involuntarily dropping his voice, as one does in the presence of danger:

“Will that change your plans, Mul-tal-la?”

He thought for a minute, with his eyes still on the smoke, before answering.

“Mul-tal-la cannot speak of a surety, but he does not think so.”

As he explained matters from his point of view, the former course that he had indicated remained the right one to follow. The discovery simply added another element of danger to that which was there from the first. By kindling the fire where they had halted, they would give the impression that they had gone into camp for the night. This subterfuge ought to lure the Shoshones to the place in order to make their attack during the darkness.

The situation could not have been more delicate. To carry out the plan of the Blackfoot it was necessary for him and his companions to set out over the pass as soon as it became dark. They would thus be going directly toward the hostiles, who, in case they did not wait until a late hour, would be coming at the same time toward the travelers. Using the one road, it would seem that an encounter was inevitable.

The hope of averting such a meeting rested on the fact that the pass was of varying width, and in many places two or three routes were open. Two men following opposite directions might miss each other by a half-mile interval, and without the possibility of mutual discovery. Again there were stretches where they would have to come face to face. A not important advantage of our friends was that they would be expecting—and would, therefore, be on the lookout for—the Shoshones, while it was not likely the latter would be watching for the Blackfoot and the boys, who were supposed to be at the entrance to the pass, where the smoke of their camp-fire spoke of their presence.

A vigorous blaze having been started, Mul-tal-la took the lead as before. It was understood that he was to hold his place considerably farther in advance than usual. Upon the first sign of their enemies he would warn them by signal, when they could conceal themselves, if possible, until the hostiles passed down the trail to the supposed camp. If this could be accomplished, the danger would be past and the problem solved. Everything depended upon the skill of the Blackfoot.
