Yet he felt a momentary exultation. Boyd and he would find a path through every peril. His walk brought him back to the edge of the brook, where for a little space thick bushes grew, and he heard a snarling growl, followed by a rush that could be made only by a heavy body. He started violently, the pulses beat hard in his temples and he promptly presented his rifle. Then he laughed at himself. He caught a glimpse of a long, yellowish body and he knew it was a mountain lion, much more alarmed than he, and fleeing with all speed to the hills.

He must be steadier of nerve and he gave himself a stern rebuke. Farther down the valley the brook widened again into a deep pool, and in the water, as clear as silver, he saw fine mountain trout, darting here and there. If they stayed a day or two in the valley he would come and catch several of the big fellows, as they were well provided with fishing tackle, which Boyd said would be a great resource, saving much ammunition.

He went farther, and then climbed the hill which enclosed the valley on that side, obtaining from its crest a northern view of rolling plains, with the dim blue outline of the high mountains far beyond. He surmised that the group of hills in which they now lay was of limited area, and that when they continued their journey they must take once more to the plains, where they would be exposed to the view of roving Sioux. His heart throbbed as he looked over that great open expanse, and realized anew the danger. The pocket in the hills in which they lay was surely a safe and comfortable place, and one need be in no hurry to abandon it.

When he went back to the camp Boyd was just awakening, and as he looked at Will his eyes twinkled.

"Well, what did you find?" he asked. "Anything besides tracks of animals?"

"I found an animal himself," replied the lad. "I scared him up in the bushes at the brook's edge. It was a mountain lion and he ran away, just as I felt like doing at first."

The hunter laughed with genuine pleasure.

"I'm glad you kept down the feeling and didn't run," he said. "You'll get over such tremors in time. Everybody feels 'em, no matter how brave, unless he has a lot of experience. Now, since you've been scouting about, what do you think we ought to do?"

"I looked from a hill and saw open plains, extending maybe forty or fifty miles. Red Cloud and his men may have gone that way and I'm in favor of giving 'em a good start. Suppose we stay here another night and day and let 'em reach the mountains."

"Seems a good plan to me."
