“And if he doesn’t, I will!” asserted Roger, impulsively, for he hated a coward and a bully above all things.

“What does Beaver Tail mean to do?” Dick asked.

“I think his first act will be to send the spy back again, so as to keep track of what is going on in the French camp,” Mayhew told him. “Then at a later hour all of us will creep over and surround the place. Any Blackfeet who may be found are apt to be given a short shrift, because they are the mortal foes of the Sioux; but I do not believe the traders will be harmed, unless they should be unwise enough to shoot one of Beaver Tail’s warriors.”

Shortly afterwards Dick saw the same skillful scout go forth, and he knew that Mayhew had guessed the truth when he said a close watch was to be kept over the camp on the lake shore.

In good time the signal would be given for the general advance. Until then, all of them must possess their souls in patience. As the cold of the night increased it was likely to prove no laughing matter, since they were unprovided with blankets, and dared not build a fire. Still, with success so close to their hands, the pioneer boys felt that they could put up with almost anything.

How slowly the time passed, in spite of all these brave resolutions! Roger found it necessary several times to get up and, as noiselessly as possible, thresh his arms around him, so as to start his stagnant blood into renewed circulation. Had it not been for this expedient he believed he would be unable to respond when finally the signal was given to move on.

When it appeared to Roger that many hours must have passed, he was elated to discover that the chief, Beaver Tail, had begun to show signs of life. He had been sitting like a block of stone, simply casting a look up at the stars occasionally, as though one of the heavenly bodies must reach a certain altitude before the time could be reckoned as up.

This must have been a signal to the others, for immediately each warrior was on his moccasined feet, and on every side bows could be seen being strung in readiness for twanging, while quivers of arrows were fastened over the left shoulder of each soft-footed brave.

Once the expedition was in motion, the chill soon left Roger’s body. In its place he experienced a gratifying warmth that must have started through the increased pumping of his youthful heart due to excitement.

The boys found as they advanced that the crafty Sioux chief had made as complete arrangements as any war captain could have done. He had divided his force into three sections of about equal numbers. One of these was sent ahead, and it was easy to surmise that the duty of these warriors was to proceed to the further extremity of the Frenchmen’s camp, so as to cut off escape from that quarter.
