"I think we have proved that Charlie Fortescue is innocent," he said. "Don't you?"

"Yes," Percy nodded. "But I wouldn't tell any of Dick's chums, here, anything about it, eh? You'll keep it quiet, won't you?"

"Why, cert'nly!" agreed Silk.


CHAPTER III

THE MYSTERY OF GREY WOLF FOREST

There were two boys in the household of Rattlesnake Ranch—Percy Rapson, who had come out from England to learn farming, and Dan Medlicott, the sixteen-year-old son of the ranch mistress. They were different in many ways, these two, as might be expected when one had been brought up in an English public school and the other had spent the whole of his life in the wilds of Western Canada. But there was one thing in which they were entirely alike: they both had a tremendous respect and admiration for Sergeant Silk.

He was their hero, and they were proud to count him also as their friend. They admired him especially because he was such a splendid horseman; he could manage any horse you liked to offer him, and could subdue even the wildest of bucking bronchos. He was a sure shot, too, with rifle and revolver, and an extraordinarily fine swimmer. He excelled in all the outdoor exercises that appeal to most boys, and as for pluck and endurance, he was a constant marvel.
