Mr. Mabie frowned.

"I won't ask you which man it was, Frank; but I must warn them again to be more than

ordinarily careful about throwing matches around and leaving a fire burning anywhere in the woods. Many a grand forest has been ruined by such carelessness," he said.

"How does that happen, sir?" inquired Bluff.

"It is easy. The careless hunter or trapper leaves his dying fire when he breaks camp. Then up comes a sudden wind and some of the red cinders are blown into the dead leaves or punk grass. Fanned by the breeze, they become a roaring flame in a minute, and the mischief is done. Be careful, boys, please."

"We certainly will, sir," replied Frank sincerely. "Not to speak of the damage done, it must be mighty unpleasant to be caught in a forest fire. I've read of such things, but never hankered for a personal experience."

On the following day they started to look into the possibilities for big game around the new camp.

"Reddy, here, says he knows of a bear den that we ought to visit some time later. While at it, you boys must see all there is going in the way of sport, for you may never come out this way again, though I hope that will not be the case. To-day, however, we will take things a bit easy," remarked the ranchman.

Although the stockman did not speak any plainer, Frank knew just what he meant.

"He thinks we must be feeling the effects of our little excitement yesterday, Jerry, and that the soreness in our muscles will take our ambition away for to-day," he said aside to his chum.
